Parsing json directly using input stream

<p>I am doing a api call and in response i am getting json. So for that I want to parse it directly through input stream so that there would not be need of storing it in memory. For this I am trying to use JSONReader but that i am unable use for api's less than 11. So i dont know how to proceed with. I want it to be done from 2.0 version onwards. Even parsing through JsonReader is not working. I was thing of having GSON parser but i am not getting how to implement the same with Inputstream.</p> <p>EDIT: My code for the same:</p> <pre><code>HttpClient client = new DefaultHttpClient(); HttpGet httpGet = new HttpGet(url); try { HttpResponse response = client.execute(httpGet); StatusLine statusLine = response.getStatusLine(); int statusCode = statusLine.getStatusCode(); Log.e("123", "Status code ----------- "+statusCode); if (statusCode == 200) { HttpEntity entity = response.getEntity(); InputStream content = entity.getContent(); // for showing it on textview i am storing in in builder BufferedReader bReader = new BufferedReader(new InputStreamReader(content)); String line; while ((line = bReader.readLine()) != null) { builder.append(line); } //////////// JsonReader reader = new JsonReader(new InputStreamReader(content)); reader.setLenient(true); readGson(reader); } else { Log.e("TAG", "Failed to download file"); } } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } return builder.toString(); } private void readGson(JsonReader reader) { // TODO Auto-generated method stub Log.e("TAG", "inidde readgson"+reader); try { Log.e("TAG", "inside try"); reader.beginObject(); Log.e("123", "inside try "); while(reader.hasNext()){ Log.e("TAG", "reader values"+reader); String name = reader.nextName(); if (name.equals("max_id")) { long max_id = reader.nextLong(); Log.e("TAG", "sdbfhsajfgsdjbgksdfjv------------------"+max_id); } else { Log.e("TAG", "c skfnvklsfvn skip value"); reader.skipValue(); } } reader.endObject(); } catch (IOException e) { // TODO Auto-generated catch block Log.e("TAG", "inside catch"); e.printStackTrace(); } } </code></pre> <p>output:</p> <pre><code> 01-28 10:20:53.519: E/TAG(420): Status code ----------- 200 01-28 10:20:53.679: E/TAG(420): inidde readgsonJsonReader at line 1 column 1 01-28 10:20:53.679: E/TAG(420): inside try 01-28 10:20:53.679: E/TAG(420): inside catch 01-28 10:20:53.679: W/System.err(420): java.io.EOFException: End of input at line 1 column 1 01-28 10:20:53.689: W/System.err(420): at com.google.gson.stream.JsonReader.nextNonWhitespace(JsonReader.java:954) 01-28 10:20:53.689: W/System.err(420): at com.google.gson.stream.JsonReader.consumeNonExecutePrefix(JsonReader.java:405) 01-28 10:20:53.689: W/System.err(420): at com.google.gson.stream.JsonReader.peek(JsonReader.java:364) 01-28 10:20:53.689: W/System.err(420): at com.google.gson.stream.JsonReader.expect(JsonReader.java:337) 01-28 10:20:53.689: W/System.err(420): at com.google.gson.stream.JsonReader.beginObject(JsonReader.java:322) 01-28 10:20:53.689: W/System.err(420): at com.example.httpconnectiondemo.MainActivity.readGson(MainActivity.java:136) 01-28 10:20:53.699: W/System.err(420): at com.example.httpconnectiondemo.MainActivity.readTwitterFeed(MainActivity.java:116) 01-28 10:20:53.699: W/System.err(420): at com.example.httpconnectiondemo.MainActivity.onCreate(MainActivity.java:64) 01-28 10:20:53.699: W/System.err(420): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) 01-28 10:20:53.699: W/System.err(420): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1611) 01-28 10:20:53.699: W/System.err(420): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:1663) 01-28 10:20:53.699: W/System.err(420): at android.app.ActivityThread.access$1500(ActivityThread.java:117) 01-28 10:20:53.699: W/System.err(420): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:931) 01-28 10:20:53.699: W/System.err(420): at android.os.Handler.dispatchMessage(Handler.java:99) 01-28 10:20:53.699: W/System.err(420): at android.os.Looper.loop(Looper.java:123) 01-28 10:20:53.699: W/System.err(420): at android.app.ActivityThread.main(ActivityThread.java:3683) 01-28 10:20:53.710: W/System.err(420): at java.lang.reflect.Method.invokeNative(Native Method) 01-28 10:20:53.710: W/System.err(420): at java.lang.reflect.Method.invoke(Method.java:507) 01-28 10:20:53.710: W/System.err(420): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:839) 01-28 10:20:53.710: W/System.err(420): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:597) 01-28 10:20:53.710: W/System.err(420): at dalvik.system.NativeStart.main(Native Method) </code></pre> <p>Thanks in advance.</p>

How do you dynamically create an AWS IAM policy document with a variable number of resource blocks using terraform?

<p>In my current terraform configuration I am using a static JSON file and importing into terraform using the file function to create an AWS IAM policy.</p> <p>Terraform code:</p> <pre><code>resource "aws_iam_policy" "example" { policy = "${file("policy.json")}" } </code></pre> <p>AWS IAM Policy definition in JSON file (policy.json):</p> <pre><code>{ "Version": "2012-10-17", "Id": "key-consolepolicy-2", "Statement": [ { "Sid": "Enable IAM User Permissions", "Effect": "Allow", "Principal": { "AWS": "arn:aws:iam::111122223333:root" }, "Action": "kms:*", "Resource": "*" }, { "Sid": "Allow use of the key", "Effect": "Allow", "Principal": { "AWS": [ "arn:aws:iam::777788889999:root" ] }, "Action": [ "kms:Decrypt" ], "Resource": "*" }, { "Sid": "Allow use of the key", "Effect": "Allow", "Principal": { "AWS": [ "arn:aws:iam::444455556666:root" ] }, "Action": [ "kms:Decrypt" ], "Resource": "*" } ] } </code></pre> <p>My goal is to use a list of account numbers stored in a terraform variable and use that to dynamically build the aws_iam_policy resource in terraform. My first idea was to try and use the terraform jsonencode function. However, it looks like there might be a way to implement this using the new terraform dynamic expressions foreach loop.</p> <p>The sticking point seems to be appending a variable number of resource blocks in the IAM policy. </p> <p>Pseudo code below:</p> <pre><code>var account_number_list = ["123","456","789"] policy = {"Statement":[]} for each account_number in account_number_list: policy["Statement"].append(policy block with account_number var reference) </code></pre> <p>Any help is appreciated.</p> <p>Best, Andrew</p>

Add embedded image in emails in AWS SES service

<p>I am trying to write a Java app which can send emails to specify emails. In the email i also want to attach some pic.</p> <p>Please find my code below :-</p> <pre><code>public class AmazonSESSample { static final String FROM = "abc@gmail.com"; static final String TO = "def@gmail.com"; static final String BODY = "This email was sent through Amazon SES by using the AWS SDK for Java. hello"; static final String SUBJECT = "Amazon SES test (AWS SDK for Java)"; public static void main(String[] args) throws IOException { Destination destination = new Destination().withToAddresses(new String[] { TO }); Content subject = new Content().withData(SUBJECT); Message msg = new Message().withSubject(subject); // Include a body in both text and HTML formats //Content textContent = new Content().withData("Hello - I hope you're having a good day."); Content htmlContent = new Content().withData("&lt;h2&gt;Hi User,&lt;/h2&gt;\n" + " &lt;h3&gt;Please find the ABC Association login details below&lt;/h3&gt;\n" + " &lt;img src=\"logo.png\" alt=\"Mountain View\"&gt;\n" + " Click &lt;a href=\"http://google.com"&gt;here&lt;/a&gt; to go to the association portal.\n" + " &lt;h4&gt;Association ID - 12345&lt;/h4&gt;\n" + " &lt;h4&gt;Admin UID - suny342&lt;/h4&gt;\n" + " &lt;h4&gt;Password - poass234&lt;/h4&gt;\n" + " Regards,\n" + " &lt;br&gt;Qme Admin&lt;/br&gt;"); Body body = new Body().withHtml(htmlContent); msg.setBody(body); SendEmailRequest request = new SendEmailRequest().withSource(FROM).withDestination(destination) .withMessage(msg); try { System.out.println("Attempting to send an email through Amazon SES by using the AWS SDK for Java..."); AWSCredentials credentials = null; credentials = new BasicAWSCredentials("ABC", "CDF"); try { // credentialsProvider. } catch (Exception e) { throw new AmazonClientException("Cannot load the credentials from the credential profiles file.

Running multiple async queries with ADODB - callbacks not always firing

<p>I have an Excel workbook that fires three queries to a database to populate three tables on hidden sheets, and then runs three 'refresh' scripts to pull this data through to three visible presentation sheets (one per query). Running this synchronously is quite slow: The total time to refresh is the sum of the time of each of the three queries, plus the sum of the time for each 'refresh' script to run.</p> <p>I'm aware that VBA isn't multi-threaded, but I thought it would be possible to speed things up a bit by firing the queries off asynchronously (thus allowing some clean-up work to be done whilst they were executing), and then doing the population / refresh work for each sheet as the data comes back.</p> <p>I rewrote my script as follows (note that I've had to remove the connection strings, query strings etc and make the variables generic):</p> <pre><code>Private WithEvents cnA As ADODB.Connection Private WithEvents cnB As ADODB.Connection Private WithEvents cnC As ADODB.Connection Private Sub StartingPoint() 'For brevity, only listing set-up of cnA here. You can assume identical 'set-up for cnB and cnC Set cnA = New ADODB.Connection Dim connectionString As String: connectionString = "&lt;my conn string&gt;" cnA.connectionString = connectionString Debug.Print "Firing cnA query: " &amp; Now cnA.Open cnA.Execute "&lt;select query&gt;", adAsyncExecute 'takes roughly 5 seconds to execute Debug.Print "Firing cnB query: " &amp; Now cnB.Open cnB.Execute "&lt;select query&gt;", adAsyncExecute 'takes roughly 10 seconds to execute Debug.Print "Firing cnC query: " &amp; Now cnC.Open cnC.Execute "&lt;select query&gt;", adAsyncExecute 'takes roughly 20 seconds to execute Debug.Print "Clearing workbook tables: " &amp; Now ClearAllTables TablesCleared = True Debug.Print "Tables cleared: " &amp; Now End Sub Private Sub cnA_ExecuteComplete(ByVal RecordsAffected As Long, ...) Debug.Print "cnA records received: " &amp; Now 'Code to handle the recordset, refresh the relevant presentation sheet here, 'takes roughly &lt; 1 seconds to complete Debug.Print "Sheet1 tables received: " &amp; Now End Sub Private Sub cnB_ExecuteComplete(ByVal RecordsAffected As Long, ...) Debug.Print "cnB records received: " &amp; Now 'Code to handle the recordset, refresh the relevant presentation sheet here, 'takes roughly 2-3 seconds to complete Debug.Print "Sheet2 tables received: " &amp; Now End Sub Private Sub cnC_ExecuteComplete(ByVal RecordsAffected As Long, ...) Debug.Print "cnC records received: " &amp; Now 'Code to handle the recordset, refresh the relevant presentation sheet here, 'takes roughly 5-7 seconds to complete Debug.Print "Sheet3 tables received: " &amp; Now End Sub </code></pre> <p>Typical expected debugger output:</p> <pre><code>Firing cnA query: 21/02/2014 10:34:22 Firing cnB query: 21/02/2014 10:34:22 Firing cnC query: 21/02/2014 10:34:22 Clearing tables: 21/02/2014 10:34:22 Tables cleared: 21/02/2014 10:34:22 cnB records received: 21/02/2014 10:34:26 Sheet2 tables refreshed: 21/02/2014 10:34:27 cnA records received: 21/02/2014 10:34:28 Sheet1 tables refreshed: 21/02/2014 10:34:28 cnC records received: 21/02/2014 10:34:34 Sheet3 tables refreshed: 21/02/2014 10:34:40 </code></pre> <p>The three queries can come back in different orders depending on which finishes first, of course, so sometimes the typical output is ordered differently - this is expected.</p> <p>Sometimes however, one or two of the <code>cnX_ExecuteComplete</code> callbacks don't fire at all. After some time debugging, I'm fairly certain the reason for this is that if a recordset returns whilst one of the callbacks is currently executing, the call does not occur. For example:</p> <ul> <li>query A, B and C all fire at time 0</li> <li>query A completes first at time 3, <code>cnA_ExecuteComplete</code> fires</li> <li>query B completes second at time 5</li> <li><code>cnA_ExecuteComplete</code> is still running, so <code>cnB_ExecuteComplete</code> never fires</li> <li><code>cnA_ExecuteComplete</code> completes at time 8</li> <li>query C completes at time 10, <code>cnC_ExecuteComplete</code> fires</li> <li>query C completes at time 15</li> </ul> <p>Am I right in my theory that this is the issue? If so, is it possible to work around this, or get the call to 'wait' until current code has executed rather than just disappearing?</p> <p>One solution would be to do something extremely quick during the <code>cnX_ExecuteComplete</code> callbacks (eg, a one-liner <code>Set sheet1RS = pRecordset</code> and a check to see if they're all done yet before running the refresh scripts synchronously) so the chance of them overlapping is about zero, but want to know if there's a better solution first.</p>

Stratified sampling with Random Forests in R

<p>I read the following in the documentation of <code>randomForest</code>:</p> <blockquote> <p>strata: A (factor) variable that is used for stratified sampling.</p> <p>sampsize: Size(s) of sample to draw. For classification, if sampsize is a vector of the length the number of strata, then sampling is stratified by strata, and the elements of sampsize indicate the numbers to be drawn from the strata.</p> </blockquote> <p>For reference, the interface to the function is given by:</p> <pre><code> randomForest(x, y=NULL, xtest=NULL, ytest=NULL, ntree=500, mtry=if (!is.null(y) &amp;&amp; !is.factor(y)) max(floor(ncol(x)/3), 1) else floor(sqrt(ncol(x))), replace=TRUE, classwt=NULL, cutoff, strata, sampsize = if (replace) nrow(x) else ceiling(.632*nrow(x)), nodesize = if (!is.null(y) &amp;&amp; !is.factor(y)) 5 else 1, maxnodes = NULL, importance=FALSE, localImp=FALSE, nPerm=1, proximity, oob.prox=proximity, norm.votes=TRUE, do.trace=FALSE, keep.forest=!is.null(y) &amp;&amp; is.null(xtest), corr.bias=FALSE, keep.inbag=FALSE, ...) </code></pre> <p>My question is: How exactly would one use <code>strata</code> and <code>sampsize</code>? Here is a minimal working example where I would like to test these parameters:</p> <pre><code>library(randomForest) iris = read.table("http://archive.ics.uci.edu/ml/machine-learning-databases/iris/iris.data", sep = ",", header = FALSE) names(iris) = c("sepal.length", "sepal.width", "petal.length", "petal.width", "iris.type") model = randomForest(iris.type ~ sepal.length + sepal.width, data = iris) &gt; model 500 samples 6 predictors 2 classes: 'Y0', 'Y1' No pre-processing Resampling: Bootstrap (7 reps) Summary of sample sizes: 477, 477, 477, 477, 477, 477, ... Resampling results across tuning parameters: mtry ROC Sens Spec ROC SD Sens SD Spec SD 2 0.763 1 0 0.156 0 0 4 0.782 1 0 0.231 0 0 6 0.847 1 0 0.173 0 0 ROC was used to select the optimal model using the largest value. The final value used for the model was mtry = 6. </code></pre> <p>I come to these parameters since I would like RF to use bootstrap samples that respect the proportion of positives to negatives in my data.</p> <p><a href="https://stackoverflow.com/questions/8704681/random-forest-with-classes-that-are-very-unbalanced">This other thread</a>, started a discussion on the topic, but it was settled without clarifying how one would use these parameters.</p>

how to drag and drop files from a directory in java

<p>I want to implement dragging and dropping of files from a directory such as someones hard drive but can't figure out how to do it. I've read the java api but it talks of color pickers and dragging and dropping between lists but how to drag files from a computers file system and drop into my application. I tried writing the transferhandler class and a mouse event for when the drag starts but nothing seems to work.

Butterknife is unable to bind inside my Adapter Class

<p>I have an Adapter that draws the layouts for my Navigation Drawer. My navigation drawer contains two inner xml files: One being the <code>Header</code> and the other being the <code>Row</code>. I draw these out in a single adapter, but when I'm trying to <code>setText()</code> on my header, I get failure to bind. Here is my adapter class:</p> <pre><code>public class DrawerAdapter extends RecyclerView.Adapter&lt;DrawerAdapter.ViewHolder&gt; { private static final int HEADER_TYPE = 0; private static final int ROW_TYPE = 1; private static Context context; private static DatabaseHelper databaseHelper; private List&lt;String&gt; rows; private List&lt;Integer&gt; icons; private String driverName; public DrawerAdapter(Context context, List&lt;String&gt; rows, List&lt;Integer&gt; icons, String driverName, DatabaseHelper databaseHelper) { this.icons = icons; this.rows = rows; this.context = context; this.driverName = driverName; this.databaseHelper = databaseHelper; } @Override public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { if (viewType == HEADER_TYPE) { View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.drawer_header, parent, false); return new ViewHolder(view, viewType); } else if (viewType == ROW_TYPE) { View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.drawer_row, parent, false); return new ViewHolder(view, viewType); } return null; } @Override public void onBindViewHolder(ViewHolder holder, int position) { if (holder.viewType == ROW_TYPE) { String rowText = rows.get(position - 1); int imageView = icons.get(position - 1); holder.textView.setText(rowText); holder.imageView.setImageResource(imageView); } else if (holder.viewType == HEADER_TYPE) { holder.driverNameText.setText(driverName); } } @Override public int getItemCount() { return rows.size() + 1; } @Override public int getItemViewType(int position) { if (position == 0) return HEADER_TYPE; return ROW_TYPE; } public static class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener { protected int viewType; @Bind(R.id.drawer_row_icon) ImageView imageView; @Bind(R.id.drawer_row_text) TextView textView; @Bind(R.id.drawer_row_id) FrameLayout listRow; @Bind(R.id.driverName) TextView driverNameText; public ViewHolder(View itemView, int viewType) { super(itemView); this.viewType = viewType; if (viewType == ROW_TYPE) { ButterKnife.bind(this, itemView); imageView.setOnClickListener(this); textView.setOnClickListener(this); listRow.setOnClickListener(this); } else { ButterKnife.bind(this, itemView); } } } </code></pre> <p>As you can see in my <code>onCreateViewHolder</code> method, I'm checking for both <code>viewType</code>'s so I know which layout to draw. This in turn will create a new object for the <code>ViewHolder</code> class in which I "TRY" to bind the elements inside my xml depending on the <code>viewType</code>. Am I missing something, or doing something wrongly?</p>

jQuery Validation plugin: submitHandler not preventing default on submit when making ajax call to servlet - return false not working

<p>I have a simple form that uses jquery and a servlet. The jquery makes an ajax call to the servlet, the servlet makes some server side calculations, then displays the results on the same page via jQuery. I don't want the form to do a default submit (and go to the servlet) because I want to stay on the same page and display results dynamically. It works exactly how I want it to as is:</p> <p>HTML:</p> <pre><code>&lt;form name="form1" action="FormHandler1" method="POST" class="stats-form"&gt; &lt;input class="stats-input" id="number0" type="text" name="number0"&gt; &lt;input id="number1" type="text" name="number1"&gt; &lt;input id="number2" type="text" name="number2"&gt; &lt;input id="number3" type="text" name="number3"&gt; &lt;input type="submit" value="Calculate" class="calculate-stats" name="stats-submit"&gt; &lt;/form&gt; </code></pre> <p>jQuery:</p> <pre><code>form.submit (function(event) { $.ajax({ type: form.attr("method"), // use method specified in form attributes url: form.attr("action"), // use action specified in form attributes (servlet) data: form.serialize(), // encodes set of form elements as string for submission success: function(data) { // get response form servlet and display on page via jquery } }); event.preventDefault(); // stop form from redirecting to java servlet page }); </code></pre> <p>Now, I wanted to add form validation, since the servlet expects decimal numbers to do it's calculations. The user should only be allowed to enter numbers, no other characters. To do this I adopted the popular <a href="http://jqueryvalidation.org/" rel="nofollow">jQuery Validation</a> plugin. </p> <p>The validation works as expected, but to make my ajax call to the servlet I have to use the submitHandler jQuery Validation provides, instead of the jQuery submit method shown above. When I use the validation submitHandler, the default action of the form on submit is executed, going to the servlet page instead of staying on the same page to display my results dynamically in jQuery. I have to pass the formHandler a form, instead of an event like before, which allowed me to prevent the default action. The only option is to return false, but it doesn't work. I've been trying to figure this out for the past two days, and have pretty much exhausted my google-fu. Here is the new code giving me grief:</p> <pre><code>form.validate({ rules: { number0: ruleSet, number1: ruleSet, number2: ruleSet, number3: ruleSet, }, submitHandler: function (form) { $.ajax({ type: "POST", url: form.attr("action"), data: form.serialize(), success: function () { // get response from servlet and display on page via jQuery } }); return false; // required to block normal submit ajax used } }); </code></pre> <p>Any help would be appreciated, I'd like to use this neat jQuery form validation, but I may just write my own jQuery validation from scratch so that I can use the form submit method that I already have working.</p>

The entity or complex type ... cannot be constructed in a LINQ to Entities query

<p>Why does one method work but not the other, when it seems they are both doing the same thing, i.e. constructing an entity. My question then, is there a way to construct the entity in a L2E query instead of having to use just Linq or indeed both?</p> <p>This works fine...</p> <pre><code>var queryToList = (from ac in ctx.AuthorisationChecks where wedNumbers.Contains(ac.WedNo) orderby ac.WedNo, ac.ExpAuthDate, ac.ActAuthDate select new AuthorisationCheck { Blah = ac.Blah }).ToList(); model.AuthorisationChecks = queryToList.Select(x =&gt; new AuthorisationCheck { Blah = x.Blah }).ToList(); </code></pre> <p>However, if i change...</p> <pre><code>var queryToList </code></pre> <p>to</p> <pre><code>model.AuthorisationChecks queryToList // Of type List&lt;AuthorisationCheck&gt; </code></pre> <p>i get the error in the Title...</p> <pre><code>The entity or complex type 'Model.AuthorisationCheck' cannot be constructed in a LINQ to Entities query. </code></pre> <p><strong>EDIT:</strong> In the model it is simply, nothing fancy here.</p> <pre><code>public List&lt;AuthorisationCheck&gt; AuthorisationChecks { get; set; } </code></pre> <p><strong>EDIT2:</strong> Tidied this up a little to be (which works fine)...</p> <pre><code>model.AuthorisationChecks = (from ac in ctx.AuthorisationChecks where wedNumbers.Contains(ac.WedNo) orderby ac.WedNo, ac.ExpAuthDate, ac.ActAuthDate select ac).ToList() .Select(x =&gt; new AuthorisationCheck { Blah = x.Blah }).ToList(); </code></pre> <p><strong>EDIT2: My Solution</strong> I wasn't happy with the anonymous type method and so went ahead and created a simple model containing only the properties I required to be used in the viewmodel.</p> <p>Changed the type of model.AuthorisationChecks</p> <p>from </p> <pre><code>List&lt;AuthorisationCheck&gt; // List of Entities </code></pre> <p>to</p> <pre><code>List&lt;AuthorisationCheckModel&gt; // List of models </code></pre> <p>which allows the following code to work, and without profiling it seems a lot quicker than using an anonymous type (and of course I don't cast to a list twice!).</p> <pre><code>model.AuthorisationChecks = (from ac in ctx.AuthorisationChecks where wedNumbers.Contains(ac.WedNo) orderby ac.WedNo, ac.ExpAuthDate, ac.ActAuthDate select new AuthorisationCheckModel { Blah = x.Blah }).ToList(); </code></pre> <p>P.S. I was once warned by a coworker (who used to work for Microsoft) that it isn't a good idea to directly use Entities in this manner, maybe this was one of the reasons he was thinking of, I've also noticed some odd behavior using Entities directly in other cases (mainly corruptions).</p>

How to set linker flags for OpenMP in CMake's try_compile function

<p>I would like to verify that the current compiler can build with openmp support. The application has do deploy across a wide variety of unix systems, some of which might have old versions of OpenMP, and I would like to test for important OpenMP functionality. So, I want to build a test source file that incorporates some of the OpenMP calls.</p> <p>Thus, I created a very simple test file, and attempted to use the try_compile function from CMake. Ufortunately, it doesn't seem to apply the -fopenmp linker flag correctly.

Codeigniter Pagination From Database limit, offset

<p>I started a web application in CI 3.0, everything working smooth, I got my pagination working, but there is a problem wich I cannot figure out...</p> <p>For example, I have the following URL: <strong>localhost/statistics/api_based</strong> When navigate, $query results are displayed, links are generated, OK. But, when I navigate to <strong>page 2</strong> for example, the URL will become: <strong>localhost/statistics/dll_based/index/2</strong> and <strong>page 3</strong> will become <strong>localhost/statistics/api_based/index/3</strong> , so therefore I am using segments. Now the problem is the query that is generated:</p> <pre><code>SELECT * FROM `shield_api` ORDER BY `id` ASC limit 20 offset 2 </code></pre> <p><strong>offset 2</strong> - is the page number 2, and it should be 20, if I am correct. I am displaying 20 results per page, so first page is correctly showing results from 1 - 20, but then page 2 will display results from 2 - 21, so you get my point, it`s not OK...</p> <p>Here is my controller:</p> <pre><code>function index($offset = 0) { // Enable SSL? maintain_ssl ( $this-&gt;config-&gt;item ( "ssl_enabled" ) ); // Redirect unauthenticated users to signin page if (! $this-&gt;authentication-&gt;is_signed_in ()) { redirect ( 'account/sign_in/?continue=' . urlencode ( base_url () .

How Should VSCode Be Configured To Support A Lerna Monorepo?

<p>I have a <a href="https://github.com/lerna/lerna" rel="noreferrer">lerna</a> monorepo containing lots of packages.</p> <p>I'm trying to achieve the following:</p> <ol> <li>Ensure that VSCode provides the correct import suggestions (based on package names, not on relative paths) from one package to another.</li> <li>Ensure that I can 'Open Definition' of one of these imports and be taken to the src of that file.</li> </ol> <p>For 1. I mean that if I am navigating code within package-a and I start to type a function exported by package-b, I get a suggestion that will trigger the adding of an import: `import { example } from 'package-b'.</p> <p>For 2. I mean that if I alt/click on the name of a function exported by 'package-b' while navigating the file from a different package that has imported it, I am taken to '/packages/namespace/package/b/src/file-that-contains-function.js',</p> <p>My (lerna) monorepo is structured as standard, for example here is a 'components' package that is published as <code>@namespace/components</code>.</p> <pre><code>- packages - components - package.json - node_modules - src - index.js - components - Button - index.js - Button.js - es - index.js - components - Button - index.js - Button.js </code></pre> <p>Note that each component is represented by a directory so that it can contain other components if necessary. In this example, <code>packages/components/index</code> exports <code>Button</code> as a named export. Files are transpiled to the package's <code>/es/</code> directory.</p> <p>By default, VSCode provides autosuggestions for imports, but it is confused by this structure and, for if a different package in the monorepo needs to use <code>Button</code> for example, will autosuggest all of the following import paths:</p> <ul> <li><code>packages/components/src/index.js</code></li> <li><code>packages/components/src/Button/index.js</code></li> <li><code>packages/components/src/Button/Button.js</code></li> <li><code>packages/components/es/index.js</code></li> <li><code>packages/components/es/Button/index.js</code></li> <li><code>packages/components/es/Button/Button.js</code></li> </ul> <p>However none of these are the appropriate, because they will be rendered as relative paths from the importing file to the imported file. In this case, the following import is the correct import:</p> <pre><code>import { Button } from '@namespace/components' </code></pre> <p>Adding excludes to the project's <code>jsconfig.json</code> has no effect on the suggested paths, and doesn't even remove the suggestions at <code>/es/*</code>:</p> <pre><code>{ "compilerOptions": { "target": "es6", }, "exclude": [ "**/dist/*", "**/coverage/*", "**/lib/*", "**/public/*", "**/es/*" ] } </code></pre> <p>Explicitly adding paths using the "compilerOptions" also fails to set up the correct relationship between the files:</p> <pre><code>{ "compilerOptions": { "target": "es6", "baseUrl": ".", "paths": { "@namespace/components/*": [ "./packages/namespace-components/src/*.js" ] } }, } </code></pre> <p>At present Cmd/Clicking on an import from a different package fails to open anything (no definition is found).</p> <p><strong>How should I configure VSCode so that:</strong></p> <ol> <li><strong>VSCode autosuggests imports from other packages in the monorepo using the namespaced package as the import value.</strong></li> <li><strong>Using 'Open Definition' takes me to the src of that file.</strong></li> </ol> <p>As requested, I have a single babel config in the root:</p> <pre><code>const { extendBabelConfig } = require(`./packages/example/src`) const config = extendBabelConfig({ // Allow local .babelrc.js files to be loaded first as overrides babelrcRoots: [`packages/*`], }) module.exports = config </code></pre> <p>Which extends:</p> <pre><code>const presets = [ [ `@babel/preset-env`, { loose: true, modules: false, useBuiltIns: `entry`, shippedProposals: true, targets: { browsers: [`&gt;0.25%`, `not dead`], }, }, ], [ `@babel/preset-react`, { useBuiltIns: true, modules: false, pragma: `React.createElement`, }, ], ] const plugins = [ `@babel/plugin-transform-object-assign`, [ `babel-plugin-styled-components`, { displayName: true, }, ], [ `@babel/plugin-proposal-class-properties`, { loose: true, }, ], `@babel/plugin-syntax-dynamic-import`, [ `@babel/plugin-transform-runtime`, { helpers: true, regenerator: true, }, ], ] // By default we build without transpiling modules so that Webpack can perform // tree shaking.

How can I dynamically name an array in Javascript?

<p>I am using jQuery and JSON to pull data from a database. Each row of the database is a different product and each product has a number of properties associated with it.</p> <p>What I'm trying to do in js, is create a named array for each product containing all of the products properties. I know how to pull the data from JSON. I know how to construct the Array.</p> <p>What I don't know is how to create an array name dynamically. Can someone help me out?</p> <p>I am trying to name the array based on a field in the database. In the structure of my existing and working script, it's referenced as data.cssid. I'd like to use the value of data.cssid as the name of the array and then populate the array.</p> <pre><code>$.getJSON("products.php",function(data){ $.each(data.products, function(i,data){ var data.cssid = new Array(); data.cssid[0] = data.productid; ... etc }); }); </code></pre> <p>I know the code above is completely wrong, but it illustrates the idea. Where I declare "var data.cssid", I want to use the actual value of data.cssid as the name of the new array.</p> <p>EDIT:</p> <p>I've tried the methods mentioned here (except for eval). The code is below and is not really that different than my original post, except that I'm using a Object constructor.</p> <pre><code>$(document).ready(function(){ $.getJSON("productscript.php",function(data){ $.each(data.products, function(i,data){ var arrayName = data.cssid; obj[arrayName] = new Array(); obj[arrayName][0] = data.productid; obj[arrayName][1] = data.productname; obj[arrayName][2] = data.cssid; obj[arrayName][3] = data.benefits; alert(obj[arrayName]); //WORKS alert(obj.shoe); //WORKS WHEN arrayName = shoe, otherwise undefined }); }); }); </code></pre> <p>The alert for the non-specific obj[arrayName] works and shows the arrays in all their magnificence. But, when I try to access a specific array by name alert(obj.shoe), it works only when the arrayName = shoe. Next iteration it fails and it can't be accessed outside of this function.</p> <p>I hope this helps clarify the problem and how to solve it. I really appreciate all of the input and am trying everything you guys suggest.</p> <p>PROGRESS (THE SOLUTION):</p> <pre><code>$(document).ready(function(){ $.getJSON("productscript.php",function(data){ $.each(data.products, function(i,data){ var arrayName = data.cssid; window[arrayName] = new Array(); var arr = window[data.cssid]; arr[0] = data.productid; arr[1] = data.productname; arr[2] = data.cssid; arr[3] = data.benefits; alert(window[arrayName]); //WORKS alert(arrayName); //WORKS alert(shoe); //WORKS }); }); }); function showAlert() { alert(shoe); //WORKS when activated by button click } </code></pre> <p>Thanks to everybody for your input. </p>

Knockout.js mapping JSON object to Javascript Object

<p>I have a problem mapping a Json object recieved from the server into a predefined Javascript-object which contains all the necessary functions which are used in the bindings</p> <p>Javascript code is the following</p> <pre><code>function Person(FirstName, LastName, Friends) { var self = this; self.FirstName = ko.observable(FirstName); self.LastName = ko.observable(LastName); self.FullName = ko.computed(function () { return self.FirstName() + ' ' + self.LastName(); }) self.Friends = ko.observableArray(Friends); self.AddFriend = function () { self.Friends.push(new Person('new', 'friend')); }; self.DeleteFriend = function (friend) { self.Friends.remove(friend); }; } var viewModel = new Person(); $(document).ready(function () { $.ajax({ url: 'Home/GetPerson', dataType: 'json', type: 'GET', success: function (jsonResult) { viewModel = ko.mapping.fromJS(jsonResult); ko.applyBindings(viewModel); } }); }); </code></pre> <p>HTML:</p> <pre><code>&lt;p&gt;First name: &lt;input data-bind="value: FirstName" /&gt;&lt;/p&gt; &lt;p&gt;Last name: &lt;input data-bind="value: LastName" /&gt;&lt;/p&gt; &lt;p&gt;Full name: &lt;span data-bind="text: FullName" /&gt;&lt;/p&gt; &lt;p&gt;#Friends: &lt;span data-bind="text: Friends().length" /&gt;&lt;/p&gt; @*Allow maximum of 5 friends*@ &lt;p&gt;&lt;button data-bind="click: AddFriend, text:'add new friend', enable:Friends().length &lt; 5" /&gt;&lt;/p&gt; &lt;br&gt; @*define how friends should be rendered*@ &lt;table data-bind="foreach: Friends"&gt; &lt;tr&gt; &lt;td&gt;First name: &lt;input data-bind="value: FirstName" /&gt;&lt;/td&gt; &lt;td&gt;Last name: &lt;input data-bind="value: LastName" /&gt;&lt;/td&gt; &lt;td&gt;Full name: &lt;span data-bind="text: FullName" /&gt;&lt;/td&gt; &lt;td&gt;&lt;button data-bind="click: function(){ $parent.DeleteFriend($data) }, text:'delete'"/&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </code></pre> <p>My ServerSide MVC code for getting initial data looks like:</p> <pre><code> public ActionResult GetPerson() { Person person = new Person{FirstName = "My", LastName="Name", Friends = new List&lt;Person&gt; { new Person{FirstName = "Friend", LastName="Number1"}, new Person{FirstName = "Friend", LastName="Number2"} } }; return Json(person, JsonRequestBehavior.AllowGet); } </code></pre> <p>I am trying to use the mapping plugin to load the Json into my Javascript object so everything is available for the bindings (The add-function and the computed properties on the Friend objects).</p> <p>When I use the mapping plugin it does not seem to work. When using the plugin the AddFriend method is not available during the binding. Is it possible to populate the JavaScript Person object by using the mapping plugin or must everything be done manually?</p>

android: Data refresh in listview after deleting from database

<p>I have an application which retrieves data from DB and displays it in a list view. I have a custom adapter for the same. So when I press the "delete" button, a delete button for each row in the list is displayed. If I press that, the particular row gets deleted in the DB and the same should be reflected in the listview also. The problem is, its not reflecting this change, I should close the app and reopen or move into some other activity and get back to see the updated results.</p> <p>So my question is: where do I call the <code>notifyDataSetChanged()</code> method to get it updated instantly?</p> <p>Here is my customadapter view:</p> <pre><code>public View getView(int position, View convertView, ViewGroup parent) { // TODO Auto-generated method stub MenuListItems menuListItems = menuList.get(position); if (convertView == null) { LayoutInflater inflater = (LayoutInflater) c .getSystemService(Context.LAYOUT_INFLATER_SERVICE); convertView = inflater.inflate(R.layout.customlist, parent, false); } Button ck = (Button) convertView.findViewById(R.id.delbox); if(i){ ck.setVisibility(View.VISIBLE);} else{ ck.setVisibility(View.GONE); } ck.setTag(menuListItems.getSlno()); ck.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub final Integer Index = Integer.parseInt((String) v.getTag()); final DataHandler enter = new DataHandler(c); DialogInterface.OnClickListener dialogClickListener = new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { switch (which){ case DialogInterface.BUTTON_POSITIVE: //Yes button clicked enter.open(); enter.delet(Index); enter.close(); notifyDataSetChanged(); dialog.dismiss(); break; case DialogInterface.BUTTON_NEGATIVE: //No button clicked dialog.dismiss(); break; } } }; AlertDialog.Builder builder = new AlertDialog.Builder(c); builder.setMessage("Are you sure you want to Delete?").setPositiveButton("Yes", dialogClickListener) .setNegativeButton("No", dialogClickListener).show(); } }); TextView id = (TextView) convertView.findViewById(R.id.tvhide); id.setText(menuListItems.getSlno()); TextView title = (TextView) convertView.findViewById(R.id.tvtitle); title.setText(menuListItems.getTitle()); TextView phone = (TextView) convertView.findViewById(R.id.tvpnumber); phone.setText(menuListItems.getPhone()); // ck.setChecked(menuList.) notifyDataSetChanged(); return convertView; } </code></pre>

Using javascript to set value of hidden field then access value from serverside c# code

Open downloaded file on Android N using FileProvider

<p>I've got to fix our App for Android N due to the FileProvider changes. I've basically read all about this topic for the last ours, but no solution found did work out for me.</p> <p>Here's our prior code which starts downloads from our app, stores them in the <code>Download</code> folder and calls an <code>ACTION_VIEW</code> intent as soons as the <code>DownloadManager</code> tells he's finished downloading:</p> <pre><code>BroadcastReceiver onComplete = new BroadcastReceiver() { public void onReceive(Context ctxt, Intent intent) { Log.d(TAG, "Download commplete"); // Check for our download long referenceId = intent.getLongExtra(DownloadManager.EXTRA_DOWNLOAD_ID, -1); if (mDownloadReference == referenceId) { DownloadManager.Query query = new DownloadManager.Query(); query.setFilterById(mDownloadReference); Cursor c = mDownloadManager.query(query); if (c.moveToFirst()) { int columnIndex = c.getColumnIndex(DownloadManager.COLUMN_STATUS); if (DownloadManager.STATUS_SUCCESSFUL == c.getInt(columnIndex)) { String localUri = c.getString(c.getColumnIndex(DownloadManager.COLUMN_LOCAL_URI)); String fileExtension = MimeTypeMap.getFileExtensionFromUrl(localUri); String mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension(fileExtension); if (mimeType != null) { Intent openFileIntent = new Intent(Intent.ACTION_VIEW); openFileIntent.setDataAndTypeAndNormalize(Uri.parse(localUri), mimeType); openFileIntent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY); try { mAcme.startActivity(openFileIntent); } catch (ActivityNotFoundException e) { // Ignore if no activity was found. } } } } } } }; </code></pre> <p>This works on Android M, but breaks on N due to the popular <code>FileUriExposedException</code>. I've now tried to fix this by using the <code>FileProvider</code>, but I cannot get it to work. It's breaking when I try to get the content URI:</p> <p><code>Failed to find configured root that contains /file:/storage/emulated/0/Download/test.pdf</code></p> <p>The <code>localUri</code> returned from the <code>DownloadManager</code> for the file is:</p> <p><code>file:///storage/emulated/0/Download/test.pdf</code></p> <p>The <code>Environment.getExternalStorageDirectory()</code> returns <code>/storage/emulated/0</code> and this is the code for the conversion:</p> <pre><code>File file = new File(localUri); Log.d(TAG, localUri + " - " + Environment.getExternalStorageDirectory()); Uri contentUri = FileProvider.getUriForFile(ctxt, "my.file.provider", file); </code></pre> <p>From <code>AndroidManifest.xml</code></p> <pre><code> &lt;provider android:name="android.support.v4.content.FileProvider" android:authorities="my.file.provider" android:exported="false" android:grantUriPermissions="true"&gt; &lt;meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/file_paths"/&gt; &lt;/provider&gt; </code></pre> <p>The <code>file_paths.xml</code>:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;paths xmlns:android="http://schemas.android.com/apk/res/android"&gt; &lt;external-path name="external_path" path="." /&gt; &lt;/paths&gt; </code></pre> <p>And I've tried all values I could find in that xml file. :(</p>

Python: simple list merging based on intersections

<p>Consider there are some lists of integers as:</p> <pre><code>#-------------------------------------- 0 [0,1,3] 1 [1,0,3,4,5,10,...] 2 [2,8] 3 [3,1,0,...] ... n [] #-------------------------------------- </code></pre> <p>The question is to merge lists having at least one common element. So the results only for the given part will be as follows:</p> <pre><code>#-------------------------------------- 0 [0,1,3,4,5,10,...] 2 [2,8] #-------------------------------------- </code></pre> <p><strong>What is the most efficient way to do this on large data (elements are just numbers)?</strong> Is <code>tree</code> structure something to think about? I do the job now by converting lists to <code>sets</code> and iterating for intersections, but it is slow! Furthermore I have a feeling that is so-elementary! In addition, the implementation lacks something (unknown) because some lists remain unmerged sometime! Having said that, if you were proposing self-implementation please be generous and provide a simple sample code [apparently <strong>Python</strong> is my favoriate :)] or pesudo-code.<br> <strong>Update 1:</strong> Here is the code I was using:</p> <pre><code>#-------------------------------------- lsts = [[0,1,3], [1,0,3,4,5,10,11], [2,8], [3,1,0,16]]; #-------------------------------------- </code></pre> <p>The function is (<strong>buggy!!</strong>):</p> <pre><code>#-------------------------------------- def merge(lsts): sts = [set(l) for l in lsts] i = 0 while i &lt; len(sts): j = i+1 while j &lt; len(sts): if len(sts[i].intersection(sts[j])) &gt; 0: sts[i] = sts[i].union(sts[j]) sts.pop(j) else: j += 1 #---corrected i += 1 lst = [list(s) for s in sts] return lst #-------------------------------------- </code></pre> <p>The result is:</p> <pre><code>#-------------------------------------- &gt;&gt;&gt; merge(lsts) &gt;&gt;&gt; [0, 1, 3, 4, 5, 10, 11, 16], [8, 2]] #-------------------------------------- </code></pre> <p><strong>Update 2:</strong> To my experience the code given by <strong>Niklas Baumstark</strong> below showed to be a bit faster for the simple cases. Not tested the method given by "Hooked" yet, since it is completely different approach (by the way it seems interesting). The testing procedure for all of these could be really hard or impossible to be ensured of the results. The real data set I will use is so large and complex, so it is impossible to trace any error just by repeating. That is I need to be 100% satisfied of the reliability of the method before pushing it in its place within a large code as a module. Simply for now <strong>Niklas</strong>'s method is faster and the answer for simple sets is correct of course.<br> <strong>However how can I be sure that it works well for real large data set?</strong> Since I will not be able to trace the errors visually!</p> <p><strong>Update 3:</strong> Note that reliability of the method is much more important than speed for this problem. I will be hopefully able to translate the Python code to Fortran for the maximum performance finally.</p> <p><strong>Update 4:</strong><br> There are many interesting points in this post and generously given answers, constructive comments. I would recommend reading all thoroughly. Please accept my appreciation for the development of the question, amazing answers and constructive comments and discussion.</p>

So if someone has any idea where should i look next it would be most helpful, thanks. </p>

Rails assign session variable

<p>Hi I'm hacking around Rails the last 8 months so don't truly understand a number of things. I've seen and used helper methods that set the current_user etc. and am now trying to replicate something similar. </p> <p>I'm trying to set a global value in the application controller for the current company the user is in. I know I'm doing it wrong but I can't quite figure out how to solve it or even if I'm approaching it correctly. I want it so that when the user clicks on a company, the global variable is set to the id of the company they are in. Then in any other sub-model, if I want info on the company, I use the global variable to retrieve the company object with that id.</p> <p>The code that's causing the problem is in my navbar in <strong>application.html.erb</strong></p> <pre><code>&lt;li&gt;&lt;%= link_to "Company", company_path, :method =&gt; :get %&gt;&lt;/li&gt; </code></pre> <p>This works when I'm using the companies controller etc. But when I try use any other controller I'm getting the error</p> <blockquote> <p>ActionController::UrlGenerationError in Employees#index</p> </blockquote> <pre><code>No route matches {:action=&gt;"show", :controller=&gt;"companies"} missing required keys: [:id] </code></pre> <p>which as I understand it means it can't render the url because no company id parameter is being passed?</p> <p>I was trying to hack a helper method I used in another project (for getting the current_user) but have realised that it uses the session to extract the user.id to return a user object. Here's my attempt at the helper method in <strong>application_controller.rb</strong></p> <pre><code>def current_company @company = Company.find_by_id(params[:id]) end </code></pre> <p>I'm not able to get the current company from the session so my method above is useless unless the company id is being passed as a parameter.</p> <p>I've thought about passing the company id on every sub-model method but </p> <ol> <li>I'm not 100% sure how to do this</li> <li>It doesn't sound very efficient</li> </ol> <p>So my question is am I approaching this correctly? What's the optimal way to do it? Can I create a helper method that stores a global company id variable that gets set once a user accesses a company and can then be retrieved by other models? </p> <p>I probably haven't explained it too well so let me know if you need clarification or more info. Thanks for looking. </p> <blockquote> <p><strong><em>Edit 1</em></strong></p> </blockquote> <p>Made the changes suggested by Ruby Racer and now I have:</p> <blockquote> <p><strong>application.html.erb</strong></p> </blockquote> <pre><code> &lt;%unless current_page?(root_path)||current_page?(companies_path)||current_company.nil? %&gt; &lt;li&gt;&lt;%= link_to "Company", company_path, :method =&gt; :get %&gt;&lt;/li&gt; </code></pre> <p>This is not displaying the link in the navbar, I presume because current_company is nil (the other two unless statements were fine before I added current_company.nil?</p> <p>I'm setting the current_company in </p> <blockquote> <p><strong>companies_controller.rb</strong></p> </blockquote> <pre><code>before_action :set_company, only: [:show, :edit, :update, :destroy, :company_home] def company_home current_company = @company respond_with(@company) end </code></pre> <blockquote> <p><strong>application_controller.rb</strong></p> </blockquote> <pre><code>def current_company=(company) session[:current_company] = company.id puts "The current_company has been assigned" puts params.inspect end def current_company @company = Company.find_by_id(session[:current_company]) puts "The current_company helper has been called" puts @company puts params.inspect end </code></pre> <p>Am I doing something wrong? </p> <blockquote> <p><strong><em>Edit 2</em></strong></p> </blockquote> <p>I have no idea why this isn't working.

How to propagate errors through catchError() properly?

<p>I wrote a function that is <code>pipe</code>-able:</p> <pre class="lang-ts prettyprint-override"><code>HandleHttpBasicError&lt;T&gt;() { return ((source:Observable&lt;T&gt;) =&gt; { return source.pipe( catchError((err:any) =&gt; { let msg = ''; if(err &amp;&amp; err instanceof HttpErrorResponse) { if(err.status == 0) msg += &quot;The server didn't respond&quot;; } throw { err, msg } as CustomError }) ) }) } </code></pre> <p>I can use this function this way in my <code>HttpService</code>:</p> <pre class="lang-ts prettyprint-override"><code>checkExist(id:string) { return this.http.head&lt;void&gt;(environment.apiUrl + 'some_url/' + id) .pipe( HandleHttpBasicError(), catchError((err:CustomError) =&gt; { if(err.msg) throw err.msg; if(err.err.status == HttpStatusCodes.NOT_FOUND) throw(&quot;It doesn't exist.&quot;); throw(err); }) ) } </code></pre> <p>It's working great. When I subscribe to <code>checkExist()</code>, I get a good error message, because <code>HandleHttpBasicError</code> first catches an error and throws it to the service's <code>catchError()</code>, which throwes the error message because it was not <code>null</code>.</p> <p>This way, it allows me to have a global <code>catchError()</code> which handles error messages that will always be the same. In the future, I will do it in a <code>HttpHandler</code>, but that's not the point here.</p> <p>Is it ok to chain the errors with the <code>throw</code> keyword?</p> <p>I tried to return <code>Observable.throwError()</code>, but the browser said</p> <blockquote> <p>Observable.throwError is not a function</p> </blockquote> <p>My imports are <code>import {Observable, of, throwError} from 'rxjs';</code>.</p> <p>Isn't it better to do this:</p> <pre class="lang-ts prettyprint-override"><code>return ((source:Observable&lt;T&gt;) =&gt; { return source.pipe( catchError((err:any) =&gt; { msg = ''; ... return of({err, msg} as CustomError) /* instead of throw(err) -or- return Observable.throwError(err) (which doesn't work) */ }) ) }) </code></pre> <p>?</p>

Partial results using speech recognition

<p>I created a simple application inspired by <a href="http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/app/VoiceRecognition.html" rel="nofollow">this example</a> in order to test all the available options (ie extra). I read about the <a href="http://developer.android.com/reference/android/speech/RecognizerIntent.html#EXTRA_PARTIAL_RESULTS" rel="nofollow"><code>EXTRA_PARTIAL_RESULTS</code> extra</a> and if I enable this option I should receive from the server any partial results related to a speech recognition. However, when I add this extra to the <code>ACTION_RECOGNIZE_SPEECH</code> intent, the voice recognition does not work anymore: the list does not display any results.</p> <pre><code>protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (requestCode == VOICE_RECOGNITION_REQUEST_CODE) { switch(resultCode) { case RESULT_OK: Log.i(TAG, "RESULT_OK"); processResults(data); break; case RESULT_CANCELED: Log.i(TAG, "RESULT_CANCELED"); break; case RecognizerIntent.RESULT_AUDIO_ERROR: Log.i(TAG, "RESULT_AUDIO_ERROR"); break; case RecognizerIntent.RESULT_CLIENT_ERROR: Log.i(TAG, "RESULT_CLIENT_ERROR"); break; case RecognizerIntent.RESULT_NETWORK_ERROR: Log.i(TAG, "RESULT_NETWORK_ERROR"); break; case RecognizerIntent.RESULT_NO_MATCH: Log.i(TAG, "RESULT_NO_MATCH"); break; case RecognizerIntent.RESULT_SERVER_ERROR: Log.i(TAG, "RESULT_SERVER_ERROR"); break; default: Log.i(TAG, "RESULT_UNKNOWN"); break; } } Log.i(TAG, "Intent data: " + data); super.onActivityResult(requestCode, resultCode, data); } private void processResults(Intent data) { Log.i(TAG, "processResults()"); ArrayList&lt;String&gt; matches = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS); // list of results ListView listOfResults = (ListView)(findViewById(R.id.list_of_results)); listOfResults.setAdapter(new ArrayAdapter&lt;String&gt;(this, android.R.layout.simple_list_item_1, matches)); // number of elements of above list TextView resultsCount = (TextView)(findViewById(R.id.results_count)); resultsCount.setText(getString(R.string.results_count_label) + ": " + matches.size()); } </code></pre> <p>When this option is enabled, the number of elements in the list of results is equal to 1 and this one result is an empty string. What is the reason for this behavior?</p> <p><strong>ADDED DETAILS</strong> I used the following code in order to enable <code>EXTRA_PARTIAL_RESULTS</code> option (on Android 2.3.5).</p> <pre><code>Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH); intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, ...); intent.putExtra(RecognizerIntent.EXTRA_PARTIAL_RESULTS, true); intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 3); intent.putExtra(RecognizerIntent.EXTRA_PROMPT, ...); startActivityForResult(intent, VOICE_RECOGNITION_REQUEST_CODE); // where VOICE_RECOGNITION_REQUEST_CODE is a "global variable" </code></pre> <p>However, enabling this option, the <code>ArrayList&lt;String&gt; matches</code> in <code>processResults</code> method has only one empty element.</p>

Pandas: for loop through columns

<p>My data looks like: </p> <pre><code>SNP Name ss715583617 ss715592335 ss715591044 ss715598181 4 PI081762 T A A T 5 PI101404A T A A T 6 PI101404B T A A T 7 PI135624 T A A T 8 PI326581 T A A T 9 PI326582A T A A T 10 PI326582B T A A T 11 PI339732 T A A T 12 PI339735A T A A T 13 PI339735B T A A T 14 PI342618A T A A T </code></pre> <p>In reality I have a dataset of 50,000 columns of 479 rows. My objective is to go through each column with characters and convert the data to integers depending on which is the most abundant character.</p> <p>Right now I have the data input, and I have more or less written the function I would like to use to analyze each column separately. However, I can't quite understand how to use a forloop or use the apply function through all of the columns in the dataset. I would prefer not to hardcode the columns because I will have 40,000~50,000 columns to analyze. </p> <p>My code so far is:</p> <pre><code>import pandas as pd df = pd.read_csv("/home/dfreese/Desktop/testSNPtext", delimiter='\t') df.head() # check that the file format fits # ncol df df2 = df.iloc[4:-1] # Select the rows you want to analyze in a subset df print(df2) </code></pre> <p>My function: </p> <pre><code>def countAlleles(N): # N is just suppose to be the column, ideally once I've optimized the function # I need to analyze every column # Will hold the counts of each letter in the column letterCount = [] # This is a parallel array to know the order letterOrder = {'T','A','G','C','H','U'} # Boolean to use which one is the maximum TFlag = None AFlag = None GFlag = None CFlag = None HFlag = None UFlag = None # Loop through the column to determine which one is the maximum for i in range(len(N)): # How do I get index information of the column? if(N[i] == 'T'): # If the element in the column is T letterCount[0] = letterCount[0] + 1 elif(N[i] == 'A'): letterCount[1] = letterCount [1] + 1 elif (N[i] == 'G'): letterCount[2] = letterCount [2] + 1 elif (N[i] == 'C'): lettercount[3] = letterCount[3] + 1 elif(N[i] == 'H'): letterCount[4] = letterCount[4] + 1 else: letterCount[5] = letterCount[5] + 1 max = letterCount[0] # This will hold the value of maximum mIndex = 0 # This holds the index position with the max value # Determine which one is max for i in range(len(letterCount)): if (letterCount[i] &gt; max): max = letterCount[i] mIndex = i </code></pre> <p>So I designed the function to input the column, in hopes to be able to iterate through all the columns of the dataframe. My main question is: </p> <p>1) How would I pass each in each column as a parameter to the for loop through the elements of each column?</p> <p>My major source of confusion is how indexes are being used in pandas. I'm familiar with 2-dimensional array in C++ and Java and that is most of where my knowledge stems from.</p> <p>I'm attempting to use the apply function: </p> <pre><code>df2 = df2.apply(countAlleles('ss715583617'), axis=2) </code></pre> <p>but it doesn't seem that my application is correct.</p>

Failed to build Android app (refer to both ActionBarSherlock & ViewPagerTabs) with Ant

<p>I have one Android app which uses ActionBarSherlock &amp; ViewPagerTabs. I use Eclipse to write and build it, and it just works well until I try to build it with Ant. Here's what I did:</p> <ol> <li>go to ActionBarSherlock folder, run "android update <strong>lib-project</strong> --path ."</li> <li>go to ViewPagerTabs folder, run "android update <strong>lib-project</strong> --path ." too</li> <li>go to app folder, run "android update <strong>project</strong> --path ."</li> <li>run "and debug" under app folder, and I got following errors:</li> </ol> <p>:</p> <pre><code>[javac] C:\Android\TestApp\src\com\test\App\TestActivity.java:46: cannot find symbol [javac] symbol : method getSupportActionBar() [javac] location: class com.test.App.TestActivity [javac] final ActionBar ab = getSupportActionBar(); [javac] ^ </code></pre> <p>So question NO. 1: <strong>I have correct library references in app's project.properties, and ActionBarSherlock &amp; ViewPagerTabs could be built successfully, why do I still get these errors?</strong></p> <p>There's a workaround for this issue -- copy all classes.jar under library's bin folder into app's libs folder, and run "ant debug" again. But I need to delete these .jar files under app's libs folder after all .java files of app could be compiled.</p> <p>Running "ant debug" again after this, I will get following errors:</p> <pre><code>[dx] processing archive C:\Android\ActionBarSherlock\library\bin\classes.jar...

I think this problem is easy if html allows me to define table column by column. But html table only allows me to do it row-wise.</p> <p>Thank you very much for any help.</p>

Implementing a slider (SeekBar) in Android

<p>I want to implement a slider, which is basically two lines, one vertical and one horizontal, crossing where the screen is touched. I have managed to make one but I have to issues:</p> <ol> <li>The slider is not very smooth, there is a slight delay when I'm moving the finger</li> <li>If I place two sliders it is not multitouch, and I'd like to use both of them simultaneously</li> </ol> <p>Here is the code: </p> <pre><code>public class Slider extends View { private Controller controller = new Controller(); private boolean initialisedSlider; private int sliderWidth, sliderHeight; private Point pointStart; private Paint white; private int mode; final static int VERTICAL = 0, HORIZONTAL = 1, BOTH = 2; public Slider(Context context) { super(context); setFocusable(true); // TODO Auto-generated constructor stub } public Slider(Context context, AttributeSet attrs) { super(context, attrs); setFocusable(true); pointStart = new Point(); initialisedSlider = false; mode = Slider.BOTH; } @Override protected void onDraw(Canvas canvas) { if(!initialisedSlider) { initialisedSlider = true; sliderWidth = getMeasuredWidth(); sliderHeight = getMeasuredHeight(); pointStart.x = (int)(sliderWidth/2.0); pointStart.y = (int)(sliderHeight/2.0); controller = new Controller(pointStart, 3); white = new Paint(); white.setColor(0xFFFFFFFF); } canvas.drawLine(controller.getCoordX(),0, controller.getCoordX(),sliderHeight, white); canvas.drawLine(0, controller.getCoordY(), sliderWidth, controller.getCoordY(), white); } public boolean onTouchEvent(MotionEvent event) { int eventaction = event.getAction(); int X = (int)event.getX(); int Y = (int)event.getY(); switch (eventaction) { case MotionEvent.ACTION_DOWN: if(isInBounds(X,Y)) { updateController(X, Y); } break; case MotionEvent.ACTION_MOVE: if(isInBounds(X,Y)) { updateController(X, Y); } break; case MotionEvent.ACTION_UP: if(isInBounds(X,Y)) { updateController(X, Y); } break; } invalidate(); return true; } private boolean isInBounds(int x, int y) { return ((x&lt;=(sliderWidth)) &amp;&amp; (x&gt;=(0)) &amp;&amp; (y&lt;=(sliderHeight)) &amp;&amp; (y&gt;=(0))); } private void updateController(int x, int y) { switch(mode) { case Slider.HORIZONTAL: controller.setCoordX(x); break; case Slider.VERTICAL: controller.setCoordY(y); break; case Slider.BOTH: controller.setCoordX(x); controller.setCoordY(y); break; } } private class Controller { private int coordX, coordY; Controller() { } Controller(Point point, int width) { setCoordX(point.x); setCoordY(point.y); } public void setCoordX(int coordX) { this.coordX = coordX; } public int getCoordX() { return coordX; } public void setCoordY(int coordY) { this.coordY = coordY; } public int getCoordY() { return coordY; } } } </code></pre> <p>And the XML file: </p> <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" &gt; &lt;TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" /&gt; &lt;com.android.lasttest.Slider android:id="@+id/slider" android:layout_width="100dp" android:layout_height="100dp" android:layout_gravity="center_horizontal" android:adjustViewBounds="true"/&gt; &lt;com.android.lasttest.Slider android:id="@+id/slider" android:layout_width="150dp" android:layout_height="150dp" android:layout_gravity="center_horizontal" android:adjustViewBounds="true"/&gt; &lt;com.android.lasttest.Slider android:id="@+id/slider" android:layout_width="200dp" android:layout_height="200dp" android:layout_gravity="center_horizontal" android:adjustViewBounds="true"/&gt; &lt;/LinearLayout&gt; </code></pre>

Tee does not show output or write to file

<p>I wrote a python script to monitor the statuses of some network resources, an infinite pinger if you will. It pings the same 3 nodes forever until it receives a keyboard interrupt. I tried using tee to redirect the output of the program to a file, but it does not work:</p> <pre><code>λ sudo ./pingster.py 15:43:33 node1 SUCESS | node2 SUCESS | node3 SUCESS 15:43:35 node1 SUCESS | node2 SUCESS | node3 SUCESS 15:43:36 node1 SUCESS | node2 SUCESS | node3 SUCESS 15:43:37 node1 SUCESS | node2 SUCESS | node3 SUCESS 15:43:38 node1 SUCESS | node2 SUCESS | node3 SUCESS ^CTraceback (most recent call last): File "./pingster.py", line 42, in &lt;module&gt; main() File "./pingster.py", line 39, in main sleep(1) KeyboardInterrupt λ sudo ./pingster.py | tee ping.log # wait a few seconds ^CTraceback (most recent call last): File "./pingster.py", line 42, in &lt;module&gt; main() File "./pingster.py", line 39, in main sleep(1) KeyboardInterrupt λ file ping.log ping.log: empty </code></pre> <p>I am using <a href="https://pypi.python.org/pypi/colorama" rel="noreferrer">colorama</a> for my output, I thought that perhaps could be causing the issue, but I tried printing something before I even imported colorama, and the file is still empty.

Spark SQL UNION - ORDER BY column not in SELECT

<p>I'm doing a UNION of two temp tables and trying to order by column but spark complains that the column I am ordering by cannot be resolved.

Removing Previous Button on First Step jQuery Steps

Why is std::unordered_map slow, and can I use it more effectively to alleviate that?

<p>I’ve recently found out an odd thing. It seems that calculating Collatz sequence lengths with <a href="http://melpon.org/wandbox/permlink/xpx3rSzV6thjfz1q" rel="noreferrer">no caching at all</a> is over 2 times <em>faster</em> than <a href="http://melpon.org/wandbox/permlink/Omhqamehs2P6y7Or" rel="noreferrer">using <code>std::unordered_map</code> to cache all elements</a>.</p> <p>Note I did take hints from question <a href="https://stackoverflow.com/questions/11614106/is-gcc-stdunordered-map-implementation-slow-if-so-why">Is gcc std::unordered_map implementation slow? If so - why?</a> and I tried to used that knowledge to make <code>std::unordered_map</code> perform as well as I could (I used g++ 4.6, it did perform better than recent versions of g++, and I tried to specify a sound initial bucket count, I made it exactly equal to the maximum number of elements the map must hold).</p> <p>In comparision, <a href="http://melpon.org/wandbox/permlink/9YayIIQmPm8I1Hmm" rel="noreferrer">using <code>std::vector</code> to cache a few elements</a> was almost 17 times faster than no caching at all and almost 40 times faster than using <code>std::unordered_map</code>.</p> <p>Am I doing something wrong or is this container THAT slow and why? Can it be made performing faster? Or maybe hashmaps are inherently ineffective and should be avoided whenever possible in high-performance code?</p> <p>The problematic benchmark is:</p> <pre><code>#include &lt;iostream&gt; #include &lt;unordered_map&gt; #include &lt;cstdint&gt; #include &lt;ctime&gt; std::uint_fast16_t getCollatzLength(std::uint_fast64_t val) { static std::unordered_map &lt;std::uint_fast64_t, std::uint_fast16_t&gt; cache ({{1,1}}, 2168611); if(cache.count(val) == 0) { if(val%2 == 0) cache[val] = getCollatzLength(val/2) + 1; else cache[val] = getCollatzLength(3*val+1) + 1; } return cache[val]; } int main() { std::clock_t tStart = std::clock(); std::uint_fast16_t largest = 0; for(int i = 1; i &lt;= 999999; ++i) { auto cmax = getCollatzLength(i); if(cmax &gt; largest) largest = cmax; } std::cout &lt;&lt; largest &lt;&lt; '\n'; std::cout &lt;&lt; "Time taken: " &lt;&lt; (double)(std::clock() - tStart)/CLOCKS_PER_SEC &lt;&lt; '\n'; } </code></pre> <p>It outputs: <code>Time taken: 0.761717</code></p> <p>Whereas a benchmark with no caching at all:</p> <pre><code>#include &lt;iostream&gt; #include &lt;unordered_map&gt; #include &lt;cstdint&gt; #include &lt;ctime&gt; std::uint_fast16_t getCollatzLength(std::uint_fast64_t val) { std::uint_fast16_t length = 1; while(val != 1) { if(val%2 == 0) val /= 2; else val = 3*val + 1; ++length; } return length; } int main() { std::clock_t tStart = std::clock(); std::uint_fast16_t largest = 0; for(int i = 1; i &lt;= 999999; ++i) { auto cmax = getCollatzLength(i); if(cmax &gt; largest) largest = cmax; } std::cout &lt;&lt; largest &lt;&lt; '\n'; std::cout &lt;&lt; "Time taken: " &lt;&lt; (double)(std::clock() - tStart)/CLOCKS_PER_SEC &lt;&lt; '\n'; } </code></pre> <p>Outputs <code>Time taken: 0.324586</code></p>

Reading from a cryptostream to the end of the stream

This means that if I attempt to decrypt the file, I get a file already in use error! </p> <p>Tried all the usual and Ive looked on here at similar issues, any help would be great.</p> <p>Thanks</p> <pre><code>public void EncryptFile(String tempPath, String pathToSave) { try { FileStream InputFile = new FileStream(tempPath, FileMode.Open, FileAccess.Read); FileStream OutputFile = new FileStream(pathToSave, FileMode.Create, FileAccess.Write); RijndaelManaged RijCrypto = new RijndaelManaged(); //Key byte[] Key = new byte[32] { ... }; //Initialisation Vector byte[] IV = new byte[32] { ... }; RijCrypto.Padding = PaddingMode.None; RijCrypto.KeySize = 256; RijCrypto.BlockSize = 256; RijCrypto.Key = Key; RijCrypto.IV = IV; ICryptoTransform Encryptor = RijCrypto.CreateEncryptor(Key, IV); CryptoStream CryptStrm = new CryptoStream(OutputFile, Encryptor, CryptoStreamMode.Write); int data; while (-1 != (data = InputFile.ReadByte())) { CryptStrm.WriteByte((byte)data); } } catch (Exception EncEx) { throw new Exception("Encoding Error: " + EncEx.Message); } } </code></pre> <p>EDIT:</p> <p>I've made the assumption that my problem is with Encryption.

How to force FormRequest return json in Laravel 5.1?

<p>I'm using <a href="http://laravel.com/docs/5.1/validation#form-request-validation">FormRequest</a> to validate from which is sent in an API call from my smartphone app. So, I want FormRequest alway return json when validation fail.</p> <p>I saw the following source code of Laravel framework, the default behaviour of FormRequest is return json if reqeust is Ajax or wantJson.</p> <pre><code>//Illuminate\Foundation\Http\FormRequest class /** * Get the proper failed validation response for the request. * * @param array $errors * @return \Symfony\Component\HttpFoundation\Response */ public function response(array $errors) { if ($this-&gt;ajax() || $this-&gt;wantsJson()) { return new JsonResponse($errors, 422); } return $this-&gt;redirector-&gt;to($this-&gt;getRedirectUrl()) -&gt;withInput($this-&gt;except($this-&gt;dontFlash)) -&gt;withErrors($errors, $this-&gt;errorBag); } </code></pre> <p>I knew that I can add <code>Accept= application/json</code> in request header. FormRequest will return json. But I want to provide an easier way to request my API by support json in default without setting any header. So, I tried to find some options to force FormRequest response json in <code>Illuminate\Foundation\Http\FormRequest</code> class. But I didn't find any options which are supported in default. </p> <h2>Solution 1 : Overwrite Request Abstract Class</h2> <p>I tried to overwrite my application request abstract class like followings:</p> <pre><code>&lt;?php namespace Laravel5Cg\Http\Requests; use Illuminate\Foundation\Http\FormRequest; use Illuminate\Http\JsonResponse; abstract class Request extends FormRequest { /** * Force response json type when validation fails * @var bool */ protected $forceJsonResponse = false; /** * Get the proper failed validation response for the request. * * @param array $errors * @return \Symfony\Component\HttpFoundation\Response */ public function response(array $errors) { if ($this-&gt;forceJsonResponse || $this-&gt;ajax() || $this-&gt;wantsJson()) { return new JsonResponse($errors, 422); } return $this-&gt;redirector-&gt;to($this-&gt;getRedirectUrl()) -&gt;withInput($this-&gt;except($this-&gt;dontFlash)) -&gt;withErrors($errors, $this-&gt;errorBag); } } </code></pre> <p>I added <code>protected $forceJsonResponse = false;</code> to setting if we need to force response json or not. And, in each FormRequest which is extends from Request abstract class. I set that option. </p> <p>Eg: I made an StoreBlogPostRequest and set <code>$forceJsoResponse=true</code> for this FormRequest and make it response json.</p> <pre><code>&lt;?php namespace Laravel5Cg\Http\Requests; use Laravel5Cg\Http\Requests\Request; class StoreBlogPostRequest extends Request { /** * Force response json type when validation fails * @var bool */ protected $forceJsonResponse = true; /** * Determine if the user is authorized to make this request. * * @return bool */ public function authorize() { return true; } /** * Get the validation rules that apply to the request. * * @return array */ public function rules() { return [ 'title' =&gt; 'required|unique:posts|max:255', 'body' =&gt; 'required', ]; } } </code></pre> <h2>Solution 2: Add an Middleware and force change request header</h2> <p>I build a middleware like followings: <pre><code>namespace Laravel5Cg\Http\Middleware; use Closure; use Symfony\Component\HttpFoundation\HeaderBag; class AddJsonAcceptHeader { /** * Add Json HTTP_ACCEPT header for an incoming request. * * @param \Illuminate\Http\Request $request * @param \Closure $next * @return mixed */ public function handle($request, Closure $next) { $request-&gt;server-&gt;set('HTTP_ACCEPT', 'application/json'); $request-&gt;headers = new HeaderBag($request-&gt;server-&gt;getHeaders()); return $next($request); } } </code></pre> <p>It 's work. But I wonder is this solutions good? And are there any Laravel Way to help me in this situation ? </p>

How to setup conditionals for BPMN2 Exclusive Gateway

<p>I'm using Camunda BPMN2 for the first time in my spring project and trying to get my head around a couple of things ...</p> <p>In my applicationContext, I have the following block to setup Camunda:</p> <pre><code> &lt;!-- Setup BPMN Process Engine --&gt;

I am getting the error in the line when i try to create the object for Parser1 class.</p> <pre><code>06-06 10:05:43.742: WARN/dalvikvm(224): VFY: unable to resolve static method 3084: Lorg/codehaus/jackson/JsonToken;.values ()[Lorg/codehaus/jackson/JsonToken; 06-06 10:05:43.742: DEBUG/dalvikvm(224): VFY: replacing opcode 0x71 at 0x0005 06-06 10:05:43.742: DEBUG/dalvikvm(224): Making a copy of Lcom/support/utils/Parser1;.$SWITCH_TABLE$org$codehaus$jackson$JsonToken code (522 bytes) 06-06 10:05:43.752: WARN/dalvikvm(224): VFY: unable to find class referenced in signature (Lorg/codehaus/jackson/JsonParser;) 06-06 10:05:43.752: INFO/dalvikvm(224): Could not find method org.codehaus.jackson.JsonParser.getCurrentToken, referenced from method com.support.utils.Parser1.addSectionContentData 06-06 10:05:43.761: WARN/dalvikvm(224): VFY: unable to resolve virtual method 3077: Lorg/codehaus/jackson/JsonParser;.getCurrentToken ()Lorg/codehaus/jackson/JsonToken; 06-06 10:05:43.761: DEBUG/dalvikvm(224): VFY: replacing opcode 0x74 at 0x0002 06-06 10:05:43.761: DEBUG/dalvikvm(224): Making a copy of Lcom/support/utils/Parser1;.addSectionContentData code (2421 bytes) 06-06 10:05:43.761: WARN/dalvikvm(224): VFY: unable to resolve exception class 685 (Lorg/codehaus/jackson/JsonParseException;) 06-06 10:05:43.771: WARN/dalvikvm(224): VFY: unable to resolve exception class 685 (Lorg/codehaus/jackson/JsonParseException;) 06-06 10:05:43.771: WARN/dalvikvm(224): VFY: unable to resolve exception class 685 (Lorg/codehaus/jackson/JsonParseException;) 06-06 10:05:43.771: WARN/dalvikvm(224): VFY: unable to find exception handler at addr 0x19b 06-06 10:05:43.771: WARN/dalvikvm(224): VFY: rejected Lcom/support/utils/Parser1;.addSectionContentData (Lorg/codehaus/jackson/JsonParser;Ljava/util/List;Lcom/support/ModelClasses/SectionContent;Lcom/support/ModelClasses/FeatureInfo;ZZLjava/lang/String;)Ljava/util/List; 06-06 10:05:43.781: WARN/dalvikvm(224): VFY: rejecting opcode 0x0d at 0x019b 06-06 10:05:43.781: WARN/dalvikvm(224): VFY: rejected Lcom/support/utils/Parser1;.addSectionContentData (Lorg/codehaus/jackson/JsonParser;Ljava/util/List;Lcom/support/ModelClasses/SectionContent;Lcom/support/ModelClasses/FeatureInfo;ZZLjava/lang/String;)Ljava/util/List; 06-06 10:05:43.781: WARN/dalvikvm(224): Verifier rejected class Lcom/support/utils/Parser1; 06-06 10:05:43.793: WARN/dalvikvm(224): threadid=15: thread exiting with uncaught exception (group=0x4001b188) 06-06 10:05:43.793: ERROR/AndroidRuntime(224): Uncaught handler: thread AsyncTask #1 exiting due to uncaught exception 06-06 10:05:43.812: ERROR/AndroidRuntime(224): java.lang.RuntimeException: An error occured while executing doInBackground() 06-06 10:05:43.812: ERROR/AndroidRuntime(224): at android.os.AsyncTask$3.done(AsyncTask.java:200) 06-06 10:05:43.812: ERROR/AndroidRuntime(224): at java.util.concurrent.FutureTask$Sync.innerSetException(FutureTask.java:273) 06-06 10:05:43.812: ERROR/AndroidRuntime(224): at java.util.concurrent.FutureTask.setException(FutureTask.java:124) 06-06 10:05:43.812: ERROR/AndroidRuntime(224): at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:307) 06-06 10:05:43.812: ERROR/AndroidRuntime(224): at java.util.concurrent.FutureTask.run(FutureTask.java:137) 06-06 10:05:43.812: ERROR/AndroidRuntime(224): at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1068) 06-06 10:05:43.812: ERROR/AndroidRuntime(224): at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:561) 06-06 10:05:43.812: ERROR/AndroidRuntime(224): at java.lang.Thread.run(Thread.java:1096) 06-06 10:05:43.812: ERROR/AndroidRuntime(224): Caused by: java.lang.VerifyError: com.support.utils.Parser1 06-06 10:05:43.812: ERROR/AndroidRuntime(224): at com.Sample.checkforversioning(Sample.java:652) 06-06 10:05:43.812: ERROR/AndroidRuntime(224): at com.Sample$checkVersionThread.doInBackground(Sample.java:682) 06-06 10:05:43.812: ERROR/AndroidRuntime(224): at com.Sample$checkVersionThread.doInBackground(Sample.java:1) 06-06 10:05:43.812: ERROR/AndroidRuntime(224): at android.os.AsyncTask$2.call(AsyncTask.java:185) 06-06 10:05:43.812: ERROR/AndroidRuntime(224): at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:305) 06-06 10:05:43.812: ERROR/AndroidRuntime(224): ... 4 more 06-06 10:05:43.832: INFO/Process(52): Sending signal.

select records from postgres where timestamp is in certain range

<p>I have arrival column of type timestamp in table reservations ( I'm using postgres ). How would I select all dates within this year for example?</p> <p>I know I could do something like this:</p> <pre><code>select * FROM reservations WHERE extract(year from arrival) = 2012; </code></pre> <p>But I've ran <strong>analyze</strong> and it looks like it require a sequence scan. Is there a better option?</p> <p><strong>P.S. 1 Hmm. both ways seem to require seq. scan. But the one by wildplasser produces results faster - why?</strong></p> <pre><code>cmm=# EXPLAIN ANALYZE select * FROM reservations WHERE extract(year from arrival) = 2010; QUERY PLAN --------------------------------------------------------------------------------------------------------------- Seq Scan on vrreservations (cost=0.00..165.78 rows=14 width=4960) (actual time=0.213..4.509 rows=49 loops=1) Filter: (date_part('year'::text, arrival) = 2010::double precision) Total runtime: 5.615 ms (3 rows) cmm=# EXPLAIN ANALYZE SELECT * from reservations WHERE arrival &gt; '2010-01-01 00:00:00' AND arrival &lt; '2011-01-01 00:00:00'; QUERY PLAN ----------------------------------------------------------------------------------------------------------------------------------------------- Seq Scan on reservations (cost=0.00..165.78 rows=51 width=4960) (actual time=0.126..2.491 rows=49 loops=1) Filter: ((arrival &gt; '2010-01-01 00:00:00'::timestamp without time zone) AND (arrival &lt; '2011-01-01 00:00:00'::timestamp without time zone)) Total runtime: 3.144 ms (3 rows) </code></pre> <p>** P.S. 2 - After I have created index on arrival column second way got even faster - since it looks like query uses index.

Why doesn't my <script> tag work from php file? (jQuery involved here too)

<p>Here is what I am trying to accomplish. I have a form that uses jQuery to make an AJAX call to a PHP file. The PHP file interacts with a database, and then creates the page content to return as the AJAX response; i.e. this page content is written to a new window in the success function for the <code>$.ajax</code> call. As part of the page content returned by the PHP file, I have a straightforward HTML script tag that has a JavaScript file. Specifically:</p> <pre><code>&lt;script type="text/javascript" src="pageControl.js"&gt;&lt;/script&gt; </code></pre> <p>This is not echoed in the php (although I have tried that), it is just html. The pageControl.js is in the same directory as my php file that generates the content.</p> <p>No matter what I try, I can't seem to get the <code>pageControl.js</code> file included or working in the resulting new window created in response to success in the AJAX call. I end up with errors like "Object expected" or variable not defined, leading me to believe the file is not getting included. If I copy the JavaScript directly into the PHPfile, rather than using the script tag with src, I can get it working.</p> <p>Is there something I am missing here about scope resolution between calling file, php, and the jQuery AJAX? I am going to want to include javascript files this way in the future and would like to understand what I am doing wrong.</p> <hr> <p>Hello again:</p> <p>I have worked away at this issue, and still no luck. I am going to try and clarify what I am doing, and maybe that will bring something to mind. I am including some code as requested to help clarify things a bit.</p> <p>Here is the sequence:</p> <ol> <li>User selects some options, and clicks submit button on form.</li> <li><p>The form button click is handled by jQuery code that looks like this:</p> <pre><code>$(document).ready(function() { $("#runReport").click(function() { var report = $("#report").val(); var program = $("#program").val(); var session = $("#session").val(); var students = $("#students").val(); var dataString = 'report=' +report+ '&amp;program=' +program+ '&amp;session=' +session+ '&amp;students=' +students; $.ajax({ type: "POST", url: "process_report_request.php", cache: false, data: dataString, success: function(pageContent) { if (pageContent) { $("#result_msg").addClass("successMsg") .text("Report created."); var windowFeatures = "width=800,menubar=yes,scrollbars=1,resizable=1,status=yes"; // open a new report window var reportWindow = window.open("", "newReportWindow", windowFeatures); // add the report data itself returned from the AJAX call reportWindow.document.write(pageContent); reportWindow.document.close(); } else { $("#result_msg").addClass("failedMsg") .text("Report creation failed."); } } }); // end ajax call // return false from click function to prevent normal submit handling return false; }); // end click call }); // end ready call </code></pre></li> </ol> <p>This code performs an AJAX call to a PHP file (<code>process_report_request.php</code>) that creates the page content for the new window. This content is taken from a database and HTML. In the PHP file I want to include another javascript file in the head with javascript used in the new window. I am trying to include it as follows</p> <pre><code>&lt;script src="/folder1/folder2/folder3/pageControl.js" type="text/javascript"&gt;&lt;/script&gt; </code></pre> <p>Changed path folder names to protect the innocent :) </p> <p>The pageControl.js file is actually in the same folder as the jQuery code file and the php file, but I am trying the full path just to be safe. <strong>I am also able to access the js file using the URL in the browser, and I can successfully include it in a static html test page using the script src tag.</strong></p> <p>After the javascript file is included in the php file, I have a call to one of its functions as follows (echo from php):</p> <pre><code> echo '&lt;script type="text/javascript" language="javascript"&gt;writePageControls();&lt;/script&gt;'; </code></pre> <p>So, once the php file sends all the page content back to the AJAX call, then the new window is opened, and the returned content is written to it by the jQuery code above.</p> <p><em>The <code>writePageControls</code> line is where I get the error "Error: Object expected" when I run the page.</em> However, since the JavaScript works fine in both the static HTML page and when included "inline" in the PHP file, it is leading me to think this is a path issue of some kind.</p> <p>Again, no matter what I try, my calls to the functions in the pageControls.js file do not work. <strong><em>If I put the contents of the pageControl.js file in the php file between script tags and change nothing else, it works as expected.</em></strong></p> <p>Based on what some of you have already said, I am wondering if the path resolution to the newly opened window is not correct. But I don't understand why because I am using the full path. Also to confuse matters even more, my linked stylesheet works just fine from the PHP file.</p> <p>Apologies for how long this is, but if anyone has the time to look at this further, I would greatly appreciate it. I am stumped. <strong>I am a novice when it comes to a lot of this</strong>, so if there is just a better way to do this and avoid this problem, I am all ears (or eyes I suppose...)</p>

how to dynamically add swt widgets to a composite?

<p>I'm trying to add widgets like text boxes, buttons to a composite on click of a button. I've tried , but i could only add these widgets dynamically only up to the size of the composite. My jface dialog is such that, it has a scrolled composite in which it holds a composite. In the main composite i have 3 other composites where i have to achieve this functionality, so if i add dynamic widgets to a composite it might expand, but it should not overlap existing composites down to it, rather it should adjust other composites accordingly and also i should be able to dispose those widgets on a button click. Did any one try this dynamic addition and removal of widgets before, I'm new to swt, jface .

Downloading Xcode with wget or curl

<p>I am trying to download Xcode from the Apple Developer site using just wget or curl. I think I am successfully storing the cookie I need to download the .dmg file, but I am not completely sure.</p> <p>When I run this command:</p> <pre><code>wget \ --post-data="theAccountName=USERNAME&amp;theAccountPW=PASSWORD" \ --cookies=on \ --keep-session-cookies \ --save-cookies=cookies.txt \ -O - \ https://developer.apple.com/ios/download.action?path=/ios/ios_sdk_4.1__final/xcode_3.2.4_and_ios_sdk_4.1.dmg &gt; /dev/null </code></pre> <p>A file called <code>cookies.txt</code> is created and contains something like this:</p> <pre><code>developer.apple.com FALSE / FALSE 0 XXXXXXXXXXXXXXXX XXXXXXXXXXXX developer.apple.com FALSE / FALSE 0 developer.sessionToken </code></pre> <p>I'm not completely certain, but I think there should be more to it than that (specifically, an alphanumeric string after <code>sessionToken</code>).</p> <p>When I try to do the same thing with curl using this:</p> <pre><code>curl \ -d "theAccountName=USERNAME&amp;theAccountPW=PASSWORD" \ -c xcode-cookie \ -A "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1" \ https://developer.apple.com/ios/download.action?path=/ios/ios_sdk_4.1__final/xcode_3.2.4_and_ios_sdk_4.1.dmg </code></pre> <p>I get a file called <code>xcode-cookie</code> that contains the same information as the <code>cookies.txt</code> file wget gives me, except that the lines are reversed.</p> <p>I then tried to download the .dmg file.</p> <p>Using wget:</p> <pre><code>wget \ --cookies=on \ --load-cookies=cookies.txt \ --keep-session-cookies \ http://developer.apple.com/ios/download.action?path=/ios/ios_sdk_4.1__final/xcode_3.2.4_and_ios_sdk_4.1.dmg </code></pre> <p>This gives me a file called <code>login?appIdKey=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX&amp;path=%2F%2Fios%2Fdownload.action?path=%2Fios%2Fios_sdk_4.1__final%2Fxcode_3.2.4_and_ios_sdk_4.1.dmg </code>, which is just an HTML page containing the login form for the developer site.</p> <p>Using curl:</p> <pre><code>curl \ -b xcode-cookie \ -c xcode-cookie \ -O -v \ -A "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1" \ https://developer.apple.com/ios/download.action?path=/ios/ios_sdk_4.1__final/xcode_3.2.4_and_ios_sdk_4.1.dmg </code></pre> <p>Which prints basically the same thing as wget (minus the HTML).</p> <p>I want to say it has to do with the sessionToken not being in the cookie, but like I said before I am not sure.

VBA Excel - Compile Error Object Required

<p><strong>Disclosure: I'm fairly inexperienced at coding of most sorts but have a reasonable understanding of the logic behind it and quite often just need a little push with getting syntax's right etc.</strong></p> <p><strong>I posted the same code earlier but with a different problem and have no discovered this issue so I thought it best to create a new question for it</strong></p> <p><strong>Objective:</strong> What I'm trying to do is create a spreadsheet where across the top row is a list of consecutive dates. In the first few columns is data for bills etc. What I want my macro to do is look at the amount of a bill, the start and end dates and the frequency of the bill (weekly/monthly etc) and then populate the cells in that same row in the columns of the dates where the bill is due. I've spent the last day coming up with this code and I was pretty happy with it until I went to run it. I've already got rid of a few bugs where I was using a variable.Value which apparently doesn't exist and I had messed up the syntax for Cells(row, column).</p> <p>The problem that I'm coming up against now is Compile Error: Object Required on this line: </p> <pre><code>Set dateAddress = Range("J1:AAI1").Find(currentDate, LookIn:=xlValues).Address 'find the current date within the range of dates in row 1 </code></pre> <p>What that line is supposed to be doing is searching across all the dates in the first row for that 'currentDate' and then storing that as dateAddress so that I can then use the dateAddress.Column in the next line of code along with the currentRow, to find the right cell that is to be populated with the bill amount.</p> <p>Am I being clear enough?

Disable all dialog boxes in Excel while running VB script?

<p>I have some code in VB that saves all XLSM files as XLSX. I already have the code that will do that for me, but dialog boxes show up for every action. This was fine for a few dozen files. However, I'm going to use this on hundreds of XLSM files at once, and I can't just sit at my computer all day clicking dialog boxes over and over. </p> <p>The code I've tried is pretty much:</p> <pre><code>Application.DisplayAlerts = False </code></pre> <p>While this doesn't cause an error, it also doesn't work. </p> <p>The boxes give a warning about enabling macros, and also warn that saving as XLSX strips the file of all macros. Considering the type of warnings, I suspect that they've restricted turning off those dialog boxes due to the security risk. </p> <p>Since I'm running this code in Excel's VB editor, is there perhaps an option that will allow me to disable dialog boxes for debugging?</p> <p>I've also tried:</p> <pre><code>Application.DisplayAlerts = False Application.EnableEvents = False ' applied code Application.DisableAlerts = True Application.EnableEvents = True </code></pre> <p>Neither of those worked. </p> <p><strong>Edit:</strong></p> <p>Here's what the code above looks like in my current code:</p> <pre><code>Public Sub example() Application.DisplayAlerts = False Application.EnableEvents = False For Each element In sArray XLSMToXLSX(element) Next element Application.DisplayAlerts = False Application.EnableEvents = False End Sub Sub XLSMToXLSX(ByVal file As String) Do While WorkFile &lt;&gt; "" If Right(WorkFile, 4) &lt;&gt; "xlsx" Then Workbooks.Open Filename:=myPath &amp; WorkFile Application.DisplayAlerts = False Application.EnableEvents = False ActiveWorkbook.SaveAs Filename:= _ modifiedFileName, FileFormat:= _ xlOpenXMLWorkbook, CreateBackup:=False Application.DisplayAlerts = True Application.EnableEvents = True ActiveWorkbook.Close End If WorkFile = Dir() Loop End Sub </code></pre> <p>I also surrounded the <code>For</code> loop, as opposed to the <code>ActiveWorkbook.SaveAs</code> line:</p> <pre><code>Public Sub example() For Each element In sArray XLSMToXLSX(element) Next element End Sub </code></pre> <p>Finally, I shifted the <code>Application.DisplayAlerts</code> above the <code>Workbooks.Open</code> line:</p> <pre><code>Sub XLSMToXLSX(ByVal file As String) Do While WorkFile &lt;&gt; "" If Right(WorkFile, 4) &lt;&gt; "xlsx" Then Workbooks.Open Filename:=myPath &amp; WorkFile Application.DisplayAlerts = False Application.EnableEvents = False ActiveWorkbook.SaveAs Filename:= _ modifiedFileName, FileFormat:= _ xlOpenXMLWorkbook, CreateBackup:=False Application.DisplayAlerts = True Application.EnableEvents = True ActiveWorkbook.Close End If WorkFile = Dir() Loop End Sub </code></pre> <p>None of those work as well.</p> <p><strong>Edit:</strong></p> <p>I'm using Excel for Mac 2011, if that helps. </p>

How to refresh Material-Table (Material-ui) component in ReactJS when data changes

Typescript build getting errors from node_modules folder

<p>I am running a typescript build and getting errors in node_modules. Why isn't it ignoring this folder? I have it in the exclude section of my tsconfig.json. The really strange thing is that I have another project that I have done a file comparison with and it does not throw these errors even though gulpfile.js, tsconfig.json and the node_modules folders are identical.

Hibernate Session is closed in spring transaction after calling method second time

<p>First of all I am a beginner in spring.I have created a simple Spring service that has DAO injected and transaction is managed by HibernateTransactionManager of spring, like as below.(And transaction configuration is used using annotations )</p> <pre><code>@Service(value="daopowered") public class UserServiceImplDao implements UserService { @Inject private UserDao userDao; @Override @Transactional public User autheticate( String userId, String password ) { return userDao.findByIdAndPassword(userId, password); } </code></pre> <p>My transaction configuration is following </p> <pre><code>&lt;bean id="txMgr" class="org.springframework.orm.hibernate3.HibernateTransactionManager"&gt; &lt;property name="sessionFactory" ref="sessionFactory" /&gt; &lt;property name="dataSource" ref="dataSource" /&gt; &lt;/bean&gt; &lt;tx:annotation-driven transaction-manager="txMgr" /&gt; </code></pre> <p>Now the problem is when I call authenticate method first time using some controller then it works fine ( does DB operations successfully) but after calling it again second time hibernate session is closed exception is coming ?

Getting bad_array_new_length error when trying to load a text file into a dynamically allocated 2d array

<p>So the issue I'm having with this code is that when I run it, I get the error: <code>terminate called after throwing an instance of "std:bad_array_new_length" what(): std:: bad_array_new_length</code> There are no errors otherwise and the code compiles just fine. Below is the text file I'm trying to load:</p> <pre> 10 8 0 255 255 255 0 0 255 255 255 0 255 0 255 255 0 0 255 255 0 255 255 255 0 255 255 255 255 0 255 255 255 255 255 0 255 255 0 255 255 255 255 255 255 355 0 0 255 255 255 255 255 255 255 255 0 0 255 255 255 255 255 255 255 0 255 255 0 255 255 255 0 0 0 255 255 255 255 0 0 0 </pre> <p>The first two values (10/8) are the length(rows) and height(columns) and the rest are meant to be stored in the 2d array.</p> <pre><code>#include &lt;iostream&gt; #include &lt;fstream&gt; #include &lt;string&gt; #include "image.h" // Has the prototypes for the functions using namespace std; int** load(string imageFile, int &amp;length, int &amp;height) { int** array = new int*[length]; ifstream file(imageFile); if(file.is_open()) { file &gt;&gt; length; // Takes the first value and stores it as length file &gt;&gt; height; // Takes the second value and stores it as height for(int i = 0; i &lt; length; i++) { array[i] = new int[height]; for(int j = 0; j &lt; height; j++) { file &gt;&gt; array[i][j]; } } } else { cout &lt;&lt; "Unable to open file." &lt;&lt; endl; return 0; } return array; } int main() { int height, length; int **image = load("../resource/imagecorrupted.txt", length, height); } </code></pre> <p>I should add that this is for a homework assignment, so I'm therefor pretty restricted in the things I can do. In main I do need to store the values from load into **image, as well as the function parameters being set out for me, and are unchangeable. Also, it's still pretty early on in the class so for this assignment we aren't expected to use structs or classes or anything like that. Thanks for any help/advice you can give me!</p> <p>EDIT:</p> <p>Thanks to @IgorTandetnik talking me through my issue, I found the fix. This new code works, should anyone have the same issue in the future and needs help:</p> <pre><code>int** load(string imageFile, int &amp;length, int &amp;height) { ifstream file(imageFile); if(file.is_open()) { file &gt;&gt; length; int** array = new int*[length]; file &gt;&gt; height; for(int i = 0; i &lt; length; i++) { array[i] = new int[height]; for(int j = 0; j &lt; height; j++) { file &gt;&gt; array[i][j]; } } return array; } else { cout &lt;&lt; "Unable to open file." &lt;&lt; endl; return 0; } } int main() { int height = 0; int length = 0; int **image = load("../resource/imagecorrupted.txt", length, height); } </code></pre>
