How to cache information in a DAO in a threadsafe manner

<p>I often need to implement DAO's for some reference data that doesn't change very often. I sometimes cache this in collection field on the DAO - so that it is only loaded once and explicitly updated when required. </p> <p>However this brings in many concurrency issues - what if another thread attempts to access the data while it is loading or being updated. </p> <p>Obviously this can be handled by making both the getters and setters of the data synchronised - but for a large web application this is quite an overhead.</p> <p>I've included a trivial flawed example of what I need as a strawman. Please suggest alternative ways to implement this. </p> <pre><code>public class LocationDAOImpl implements LocationDAO { private List&lt;Location&gt; locations = null; public List&lt;Location&gt; getAllLocations() { if(locations == null) { loadAllLocations(); } return locations; } </code></pre> <p>For further information I'm using Hibernate and Spring but this requirement would apply across many technologies. </p> <p>Some further thoughts:</p> <p>Should this not be handled in code at all - instead let ehcache or similar handle it? Is there a common pattern for this that I'm missing? There are obviously many ways this can be achieved but I've never found a pattern that is simple and maintainable.</p> <p>Thanks in advance!</p>

Re-order Items in a ListBox - Windows Forms - (Java programmer learning C#)

<p>There is the first time I'm going to do a particular control in C#. The control is a ListBox of items that will have an up arrow and a down arrow on the side. When you select an item in the ListBox, you can use the up and down arrow arrows to reposition that item in the ListBox. </p> <p>My two questions are: (1) Is there a prebuilt control for something like this, before I start writing my own?</p> <p>and if not</p> <p>(2) I'm not sure what control to use for the up / down arrows. I could use buttons that say "Up" and "Down", but I'd prefer actual arrows and am not sure the best way to go about making those.</p> <p>I am using VisualStudio2008 and .NET Framework 2.0.</p>

How can I create a tabular report in SQL when the column names are in the database, not the query?

<p><a href="http://www.geocities.com/colinpriley/sql/sqlitepg09.htm" rel="nofollow noreferrer">http://www.geocities.com/colinpriley/sql/sqlitepg09.htm</a> has a nice technique for creating a tabular report where the column names for the table can be coded in the query but in my case, the columns should be values from the database. Say I have daily sales figures like:</p> <pre><code> Transaction Date Rep Product Amount 1 July 1 Bob A12 $10 2 July 2 Bob B24 $12 3 July 2 Ted A12 $25 ... </code></pre> <p>and I want a weekly summary report that shows how much of each product each rep sold:</p> <pre><code> A12 B24 Bob $10 $12 Ted $25 $0 </code></pre> <p>My column names come from the Product column. Say, any product that has a row in the specified date range should have a column in the report. But other products -- which weren't sold in that time frame -- should not have a column of all 0s. How can I do that? Bonus points if it works in SQLite.</p> <p>TIA.</p>

C# call a static method at runtime without a build time reference?

<p>I am writing a system in C# .net (2.0). It has a pluggable module sort of architecture. Assemblies can be added to the system without rebuilding the base modules. To make a connection to the new module, I wish to attempt to call a static method in some other module by name. I do not want the called module to be referenced in any manner at build time.</p> <p>Back when I was writing unmanaged code starting from the path to the .dll file I would use LoadLibrary() to get the .dll into memory then use get GetProcAddress() get a pointer to the function I wished to call.

What is the best way to post a date/time into a django view?

<p>I'd like to build a view that allows the user to get a list of things that are happening around a certain time.</p> <p>What is the best way to build this request? E.g. If I wanted to get all of the events that are happening right now I could post to /events/2009/09/29/8/23/</p> <p>That seems rather tedious especially if I want to have multiple dates in a request. I could end up with urls that look like /events/between/2009/09/29/8/23/2006/11/16/14/45/</p> <p>Is there a simple (javascipt) way to convert a date/time to a timestamp and pass that in as an int, which I can then convert to a datetime inside the view?</p>

Rails questions, SQL statement in logs

<p>So I am new to Rails, so pardon the basic question. </p> <p>I see rails spits this out (in the console) for every request I make to my controller. Why? I'm not even doing any DB operation, I just started writing a HelloWorld rails app. I did pick mysql as the db when creating this rails project (rails -d mysql helloworld)</p> <pre><code>SQL (0.1ms) SET NAMES 'utf8' SQL (0.1ms) SET SQL_AUTO_IS_NULL=0 </code></pre> <p>So I noticed, that rails attempts to establish a DB connection for every request, irrespective whether you do a DB/ActiveRecord operation. It does this right after it does action_controller/dispatch. This seems like a waste of DB resource to me, why establish a connection to DB when I may not even do a ActiveRecord operation??</p>

What I want to do is sort the <code>event_dates</code> array in order, but if I do that, I'll lose the order of the <code>event_prices</code>.

Tkinter: Set a 'scale' value without triggering callback?

<p>I have a Tkinter GUI where there is a <code>Scale</code> object. I have a callback assigned (by the <code>command</code> constructor parameter) to perform an action when the user changes the scale position. However, there is also a case where the value represented by the scale is modified externally, and so I set the scale position using <code>Scale.set()</code>. In this case, I want to set the scale, but <em>not</em> trigger the callback, since the rest of the program already knows about the change. However, I notice that the callback is indeed triggered by <code>set()</code>.</p> <p>Is it possible to do one of:</p> <ol> <li><p>Set the scale value without triggering the callback.</p></li> <li><p>Differentiate in the callback whether it was triggered by user interaction or by <code>Scale.set()</code> being called.</p></li> </ol> <p>Thanks.</p>

access same class across two web service references in C#

<p>I'm trying to create a C# class that can call the same methods on the same classes, but the classes can come from two different web service references. I am accessing <code>SomeWebService</code> and <code>SomeWebServiceAlt</code>, where they have the same classes but are on different servers. The goal is to be able to first try using the methods in <code>SomeWebService</code>, and if that one wigs out, to try <code>SomeWebServiceAlt</code>. I was hoping to have some kind of generic class for accessing either web service, but I'm having trouble with type constraints because there aren't any common interfaces or base classes for the different classes I use from within either reference. That is, I use <code>ConnectionClass</code> from both the <code>SomeWebService</code> namespace and the <code>SomeWebServiceAlt</code> namespace, but the two <code>ConnectionClass</code> classes are not seen as related by C#, so I can't just say <code>where TClass : CommonBaseClassAcrossWebServices</code>. How should I do this? I'm ending up repeating code and doing:</p> <pre><code>if (typeof(SomeWebService.ConnectionClass) == typeof(TConnection)) { ... } else if (typeof(SomeWebServiceAlt.ConnectionClass) == typeof(TConnection)) { ... } </code></pre> <p>This seems really redundant and dirty. I'm using .NET 3.5, and I don't have control over the two web services. That's a difference between my question and similar questions I've seen on here: other people had control of the web services.</p> <p>I feel like my solution is going to end up using reflection to somehow check and see if an expected method exists, and then call that method on whichever web service's class I'm working with.</p>

How can i make writes to a gzip file from my perl script non-blocking?

<p>I'm currently writing a script that takes a database as input and generates all valid combinations from the 10+ tables, following certain rules. Since the output is pretty darn huge, i'm dumping this through gzip into the file, like this:</p> <pre><code>open( my $OUT, '|-', "gzip &gt; file" ); for ( @data ) { my $line = calculate($_); print $OUT $line; } </code></pre> <p>Due to the nature of the beast though i end up having to make hundreds of thousands of small writes, one for each line. This means that between each calculation it waits for gzip to receive the data and get done compressing it. At least i think so, i might be wrong.</p> <p>In case I'm right though, I'm wondering how i can make this print asynchronous, i.e. it fires the data at gzip and then goes on processing the data.</p>

Missing values of map(key, value) in Freemarker when access randomly?

For some reasons, we don't create hibernate relation for these domains.</p> <p>I added to model a list <code>carList</code> of <code>Car(id,name,ownerId)</code> and a <code>Map&lt;String, String&gt; map</code> which contains <code>(userId, name)</code> of <strong>all</strong> users.. It's because Freemarker only accept Map with key of type String.</p> <p>While looping through the carList, I try to get the owner name through the map.</p> <pre><code>&lt;#list carList as car&gt; ${map?values[car.ownerId]} - ${car.ownerId}&lt;br/&gt; &lt;/#list&gt; </code></pre> <p>But the strange thing is that the result I got:</p> <pre><code>Tom - 1 Jerry - 2 Jerry - 2 David - 4 - 5 - 5 </code></pre> <p>The name of user "5" is missing, but it exists in the database. Besides, when I loop through the map the result is right:</p> <pre><code>&lt;#list map?keys as key&gt; ${key} - ${map[key]} &lt;/#list&gt; </code></pre> <p>The results:</p> <pre><code>1 - Tom 2 - Jerry 3 - Mickey 4 - David 5 - Mike </code></pre> <p>The missing name happens for only a specific user.

Brand has a field called page_meta_data_id and Brand <em>belongsTo</em> PageMetaData</p> <p>Now on the view for Brand I can run this code:</p> <pre><code>if(!empty($data['PageMetaData']['title'])) { $this-&gt;set('title_for_layout', $data['PageMetaData']['title']); } else if(!empty($data['Brand']['name'])) { $this-&gt;set('title_for_layout', $data['Brand']['name']); } if(!empty($data['PageMetaData']['description'])) { echo $this-&gt;Html-&gt;meta('description', $data['PageMetaData']['description'],array('inline'=&gt;false)); } else if(!empty($data['Brand']['description'])) { echo $this-&gt;Html-&gt;meta('description', $data['Brand']['description'],array('inline'=&gt;false)); } </code></pre> <p>And if a PageMetaData has been associated to the current Brand and has a value for title, it will set that as the page title, otherwise if the brand has a field called name it will us that. Same for description.</p> <p>The problem is I don't want to have to diplicate this code in every view for every model that uses PageMetaData.</p> <p>I cannot figure out where I can abstract the code to, to avoid duplication.</p> <p>I cannot put it in a Behavior or a Helper because you cannot set the title from either. I cannot put it in a Component because it cannot access the data found from the model.</p> <p>Is there somewhere I can put this code for reuse?</p>

tomcat hbase jar inclusion

<p>I am trying to setup a simple hbase webapp using tomcat. To my knowledge I understand that i need to include the hbase jar, and hadoop jar in order to use hbase along with the zoopkeeper jar.</p> <p>The problem is when I include the hbase jar in my maven pom, it downloads all sorts od transitive dependent jars that I dont want (e.g. jetty, servlet-api etc) because hbase itself has its own in built jetty web app that is used for monitoring. I believe this conflicts with tomcat packaging and start up that results in my having the following exception:</p> <pre><code>HTTP Status 500 - type Exception report message description The server encountered an internal error () that prevented it from fulfilling this request. exception javax.servlet.ServletException: Servlet.init() for servlet jersey-serlvet threw exception org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:298) org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:857) org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:588) org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489) java.lang.Thread.run(Thread.java:619) root cause com.sun.jersey.api.container.ContainerException: No WebApplication provider is present com.sun.jersey.spi.container.WebApplicationFactory.createWebApplication(WebApplicationFactory.java:69) com.sun.jersey.spi.container.servlet.ServletContainer.create(ServletContainer.java:391) com.sun.jersey.spi.container.servlet.ServletContainer$InternalWebComponent.create(ServletContainer.java:306) com.sun.jersey.spi.container.servlet.WebComponent.load(WebComponent.java:607) com.sun.jersey.spi.container.servlet.WebComponent.init(WebComponent.java:210) com.sun.jersey.spi.container.servlet.ServletContainer.init(ServletContainer.java:373) com.sun.jersey.spi.container.servlet.ServletContainer.init(ServletContainer.java:556) javax.servlet.GenericServlet.init(GenericServlet.java:212) org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:298) org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:857) org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:588) org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489) java.lang.Thread.run(Thread.java:619) note The full stack trace of the root cause is available in the Apache Tomcat/6.0.28 logs. </code></pre> <p>When I comment out the hbase jar from my pom (all the dependent jars for hbase vanish too as expected), and tomcat deploys fine and I can access my rest/spring servlet.</p> <p>I have tried to use exclusions to excluse hbase direct dependencies with the following:</p> <pre><code>&lt;dependency&gt;

Smaller UIView in UIScrollView to stop touches

<p>I've read the various threads on this but none have given me the exact solution I need, but they have got me pretty close</p> <p>I have the topmost UIViewController which contains a paging UIScrollingView (created via the xib)</p> <p>The UIScrollingView loads an array of dummy viewcontrollers which are swapped for various viewControllers as the user swipes through the pages.</p> <p>One of these subviews contains a bunch of sliders - the usual problem: if the user misses a slider slightly they scroll the page instead.</p> <p>Within the subview I placed a UIView behind the sliders partially covering the screen: 'uiviewblocker'</p> <p>The idea is that this 'uiviewblocker' eats any touches in the immediate area around the sliders, but swipes outside the uiview are handled by the parent UIViewController. I subclassed the UIView 'uiviewblocker' to a duplicate UIViewController 'MyView' so I can detect it.</p> <p>I've got as far as...</p> <p>The parent UIScrollView:</p> <pre><code>scrollView.delaysContentTouches = NO; </code></pre> <p>The subview UIViewController</p> <pre><code>-(void)touchesBegan:(NSSet*)touches withEvent:(UIEvent*)event { NSLog(@"touchesBegan"); //[self.nextResponder touchesBegan: touches withEvent:event]; UIView *touchView = [[touches anyObject] view]; if ([touchView isKindOfClass:[MyView class]]) { NSLog(@"funky shit"); [super touchesBegan:touches withEvent:event]; //[self.delegate touchesBegan:touches withEvent:event]; //[self touchesBegain:touches withEvent:event]; // View does not respond: crashes //UIView *parent = self.view.superview; //[parent setCanCancelContentTouches:YES]; // UIView does not respond //UIScrollView * parentScrollView = (UIScrollView*)self.superview; // Superview not in structure } else { NSLog(@"normal shit"); } } </code></pre> <p>So now I can detect when the user is touching the safety area UIview by testing for it's class 'MyView' but I can't work out how to either tell the parent UIScrollView to abort or just the touch there and then</p>

mySQL delete w/ join or subquery

<p>I have a select query which works:</p> <pre><code>SELECT actions.id FROM actions LEFT JOIN users ON users.id = actions.user_id WHERE users.id is null; </code></pre> <p>And I wanted to delete these records. I tried changing the select line to "DELETE" which produced an error. I also tried a subquery:</p> <pre><code>DELETE FROM actions WHERE id IN ( SELECT actions.id FROM actions LEFT JOIN users ON users.id = actions.user_id WHERE users.id is null ); </code></pre> <p>Both attempts cause errors. While I've already solved the problem via PHP, it seems like this ought to be something the database can do with a single command. Is there a way?</p> <p>The query is basically selecting all the rows in <code>actions</code> that do not have a corresponding entry in <code>users</code> ( the tables in question are now using foreign keys so this issue won't happen again ).</p>

Page jump on span.click()

<p>I have this weird thing happening: when clicking spans in the navigation the content has to switch. Everything works except that when you click a span the page jumps to it (the span will be right at the top then). All I find about page jumps is about anchor tags and return false; but nothing about spans. In my opinion, the switching content can't be to blame because there never is only one div that has display: none (and if that was the case the page should jump to the top instead of jumping to the span, right?) Preventing any actions doesn't seem to work on spans.</p> <pre><code>$("#subnavi span").click(function(){ $("#inner-content div:visible").animate({height: "toggle", opacity: "toggle"}, "slow"); $("#content-"+this.id).animate({height: "toggle", opacity: "toggle"}, "slow"); $("#subnavi span").attr("class", ""); $(this).attr("class", "active"); }); </code></pre> <p>If the explanation was confusing, go here: <a href="http://gaming-siblings.com/v2.0/#news" rel="nofollow">http://gaming-siblings.com/v2.0/#news</a> and click Statistics in the navigation on the left. The page will jump down to the span you just clicked and scroll back a little due to the div's height. Why does it jump to the span?</p> <p>It's probably not weird but reasonable. I just don't get it :-)</p> <p>I've tried this for 2 days now, taking breaks from it because that mostly helps but not this time.</p> <p>Any ideas / solutions? As mentioned return false; or preventDefault() didn't work when I tried (because it's spans I guess).</p>

I used onResume this code, but still not working.</p> <pre><code>edittext.requestFocus(); InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE); mgr.showSoftInput(etSearch, InputMethodManager.SHOW_IMPLICIT); </code></pre> <p>help me out in this. Thanks in advance.</p>

Callbacks for arguments in Scilab

<p>I'm writing a GUI in Scilab and assigning callbacks to <code>pushbutton</code> controls. When a button is pressed, another control is affected, e.g. text inside a textbox changes. This whole routine itself (creation and initialization of the GUI) lives inside a function, that is I have to call my <code>create_my_gui()</code> to run it.</p> <p>My problem lies in variable scope and callback usage. Several of my buttons affect several other controls in exactly the same way, so I would like to use the same callback function and pass a handle to the control I'm trying to affect into the callback.</p> <p>For example when I press the <em>N</em>-th button, I'd like to pass the handle <em>N</em>-th control into the callback:</p> <pre><code>function buttonPressCallback ( controlHandle ) controlHandle.string = 'Button pressed!'; endfunction </code></pre> <p>The problem is that callbacks are defined as strings:</p> <pre><code>myButton3.callback = 'buttonPressCallback ( myTextBox3 )' </code></pre> <p>And after I've run my <code>create_my_gui()</code> function, all variables go out of scope and are destroyed, <em>including</em> handles to all controls. When I press the button, Scilab tries to run whatever string was specified as the callback and complains about the variable, <code>myTextBox3</code> for example, not existing.</p> <p>Is there a way I can refer to uicontrols in Scilab after the function that created them exited? I understand that Scilab has very peculiar ways of addressing things and perhaps I'm just not thinking in correct Scilab programming patters just yet. Is there the "right way" of doing this?</p>

TextWrangler Color Formatting and File Extensions

<p>Is there anyway to force TextWrangler to make alternate file extensions format like html? I use Twig and I like to name my templates homePage.twig, login.twig etc... But, sometimes (I don't know why) the code will not format strings, nodes and what not with alternate colors and I just end up with a big block of dark gray text. If I put at the top of the page TextWrangler will format the text, but I can't save the file that way. AND, the kicker is, this doesn't ALWAYS happen. Sometimes it will format correctly, sometimes it won't and I can't tell what is triggering it.</p> <p>Thoughts?</p>

Truncating an int (or long, or whatever) to a specific size (n bytes), signed and unsigned

<p>Say I have these two variables:</p> <pre><code>size_t value; size_t size; </code></pre> <p>And I want to "cast" <code>value</code> to the size of <code>size</code>. So if <code>size</code> is 4, <code>value</code> is casted to be 4 bytes long. If <code>size</code> is 3, <code>value</code> is presumably truncated to 3 bytes long, preserving sign (assume a signed int may be loaded into <code>value</code> then taken out later to be cast back to signed) and stored in an int/uint depending on sign choice. Preferably with a method that would work to turn, for example, an unsigned long, or whatever other integral type, to any arbitrary size in bytes along with being signed/unsigned.</p>
