Matplotlib hangs when plotting | <p>I am trying to plot some datetime objects in Python with Matplotlib, <a href="https://stackoverflow.com/questions/7684475/plotting-labeled-intervals-in-matplotlib-gnuplot">just as I have seen at this question</a>.</p>
<p>But when it gets to the savefig call, it gets stuck. This is my code:</p>
<pre><code>import matplotlib as mpl
mpl.use('Agg') # Matplotlib backend to use without an X-server
import matplotlib.pyplot as plt
from matplotlib.dates import DateFormatter, MinuteLocator
from datetime import datetime
from datetime import timedelta

filepath=None):
fig = plt.figure()
ax = fig.add_subplot(111)
y = [0.3, 0.7]
timelines(ax, y[0], prediction_start, prediction_end, color='r')
for xstart, xstop in zip(outages_start, outages_end):
timelines(ax, y[1], xstart, xstop)
ax.xaxis_date()
myFmt = DateFormatter('%d %H:%M')
ax.xaxis.set_major_formatter(myFmt)
ax.xaxis.set_major_locator(MinuteLocator(0, interval=15))
# Delta needed to adjust the xlimits
delta = (prediction_end - prediction_start) / 10
#ax.set_yticks(['Prediction', 'Outages']) #Not working
ax.set_ylim(0, 1)
ax.set_xlim(prediction_start - delta, prediction_end + delta)
ax.set_xlabel('Time')
if filepath is None:
fig.show()
else:
# Save plot as PNG
fig.savefig(filepath) # Gets stuck here
print 'PGN file saved at ' + filepath
# plot timelines at y from xstart to xstop with a given color
def timelines(current_axis, y, xstart, xstop, color='b'):
current_axis.hlines(y, xstart, xstop, color, lw=4)
current_axis.vlines(xstart, y+0.03, y-0.03, color, lw=2)

<p>I'm using Agg since I'm working without X-server into an Ubuntu Server machine, but this can't be the problem because I made a simple range plot and the figure was saved correctly, so I must be making some mistake at the code.</p>

How to combine multiple object in Laravel | <p>I want to combine my ordered products and display the order list.</p>
<p>Controller :</p>
<pre><code>$orders = Order::where('customer_id', 1)->pluck('products');
print_r($orders);
</code></pre>
<p>This is what I receive:</p>
<pre><code>Array (
[0] =>
[

</code></pre>
<p>How I can do this?</p>
<p>I already tried a different way, but I can't do this. Firstly I was trying to convert it array and then use the array_marge() function for those arrays. but that array needs only two arrays but for my case, it is not specified how many arrays the user has given. And try to solve it with a loop (I just tried). I am new in this field.</p> | 3 | 1,070 |
Why data is not being added to database? Entity Framework, Blazor wasm | <p>I have 3 tables in my database: <code>Ingredient</code>, <code>IngredientRecipe</code> and <code>Recipe</code>. Adding data to <code>Ingredient</code> works correctly. <code>IngredientRecipe</code> is for making relation between <code>Ingredient</code> and <code>Recipe</code>.

AWS CloudFormation Create-Stack Service Resource Hanging at 'CREATE_IN_PROGRESS' | <p>I have the below cloudformation script that is running fine with my create-stack command other than the service resource hanging at 'CREATE_IN_PROGRESS.'

SQLite query failing but only when offline | <p>I have a simple SQLite method which returns a class given two parameters - the type T and the parameter value to be searched</p>
<pre><code>public T GetSingleObject<T>(string id) where T:IIdentity, new()
{
lock (dbLock)
{
using (var sqlCon = new SQLiteConnection(DBPath))
{
sqlCon.Execute(Constants.DBClauseSyncOff);
sqlCon.BeginTransaction();
string sql = string.Format("SELECT * FROM {0} WHERE id=\"{1}\"", GetName(typeof(T).ToString()), id);
var data = sqlCon.Query<T>(sql);
return data[0];
}
}
}
</code></pre>
<p>I also have another method that takes 3 parameters, T, the parameter to be seated and the value to search for</p>
<pre><code>public T GetSingleObject<T>(string para, string val) where T:IIdentity, new()
{
lock (dbLock)
{
using (var sqlCon = new SQLiteConnection(DBPath))

var data = sqlCon.Query<T>(sql).FirstOrDefault();
return data;
}
}

</code></pre>
<p>These methods work without an issue and return the values expected, but with one caveat - there is a single table which works fine when the phone has a connection, but not when it's in aeroplane mode. The table has nothing more in it than strings, doubles, ints, DateTime and bool values. </p>

$resource on DELETE does not serialize data in json | <p>When using $resource with POST method (the item i want to delete on the server is of type "Todo")
My java SpringREST back controller looks like :</p>
<pre><code>/**
* POST : delete an todo : /todos/DEL
*/
@RequestMapping(value = "/DEL", method = RequestMethod.POST)
public void deletePOST(@RequestBody Todo todo) {
todoRepository.delete(todo);
}
</code></pre>
<p>Angular code :</p>
<pre><code> vm.deleteTodoRes2 = function deleteTodoRes2(todo) {
console.log(todo);
var url = REST_SERVER_URL + "/todos/DEL";
var urlParamDefaults = {};
var action = {
removeResource: {
method: 'POST',
headers: {
'Content-Type': 'application/json'
},
isArray: false,
transformRequest : function(data, headers) {
console.log("data");
console.log(data);
var out = angular.toJson(data);
console.log("out ");
console.log(out);
return out;
}
}
};
var rest = $resource(url, urlParamDefaults, action);
// API : rest.<method> ( [param],
// if NON GET [entityData],
// [success(value, responseHeaders)], [error(httpResponse)] )
var param = {};
rest.removeResource(param, todo, successCallback, errorCallback);
};
</code></pre>
<p>It works perfectlt with POST,
Now if i try changing the http method from POST to DELETE, it does not work anymore.</p>
<p>Spring :</p>
<pre><code> @RequestMapping(value = "/DEL", method = RequestMethod.DELETE) <<< only change in JAVA
In JS
var action = { removeResource: { method: 'DELETE ', <<< only change in JS
</code></pre>
<p>It does NOT WORK ,
the console.log(data); => undefined
It seems the Angular does NOT want to take my "toto" data and serialize it in json,
why ?</p> | 3 | 1,167 |
Disabled button not being styled correctly | <p>I am trying to style a button that is disabled, but the styling doesn't take effect, and go back to the old styling. I have cleared my cache, to no avail. I have a button that gets disabled using JavaScript with <code>document.getElementById("updateAccountButton").disabled = true;</code>. This aforementioned button also has the class of <code>btn-signature-green</code>. Inside my stylesheet, I am trying to set the styling of this button when disabled using:</p>
<pre><code>.btn-signature-blue:disabled, .btn-signature-green:disabled, .btn-signature-red:disabled {
/* styles go here */
}

How can a attempt a call to rename and return the results even if there is an error? | <p>I would like to iterate over a list of data frames a rename function. Sometimes the DFs will be NULL.</p>

Resolving A Django Error on Form: Object has no attribute | <p>Hi I'm trying to create a form that will when used update one model (Command_Node), and at the same time create an instance of another model (EC_NODE) that has a many to one relationship with the Command_Nodes.</p>
<p>However when I go onto the update view and submit the form I'm getting the following error any ideas on how I can resolve this error?</p>
<p>Thanks for any help you can offer.</p>
<pre><code>AttributeError at /website/update/1

<p>This on traceback points to</p>

<p>Which I can understand. I think my intention here should be clear enough. I want to set an instance of EC_Node to hold the command just put in via the form, and I understand the error. I just don't know how to get around it so that the view/form does what I want.</p>

Keep scroll visible but disable when nav menu open | <p>I have a nav menu working but the page is still scrollable when that becomes visible over the top of the rest of the content. Because the button is positioned so it's in the same place the page would jump about too much if the scroll bar was hidden. I want to disable the scrollbar on the body when the active class is active. I had tried using CSS <code>position: fixed; overflow-y:scroll</code> on body but this adds double scrolling and doesn't always revert.</p>
<p>I'm hoping the JS can be modified to keep the scrollbar present but not scrollable while the nav is open I'm just not sure how to approach this in a workable way.</p>

<p>This forces the user to pick a date range before pulling back the data.</p>
<p>An example of the data received back is:</p>
<p><a href="https://i.stack.imgur.com/9r1nQ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/9r1nQ.png" alt="enter image description here"></a></p>
<p>What is the best way to then mark this data with the Month of the range the user picks?</p>
<p>For example if they choose <strong>startdate 01/01/2019</strong> and <strong>enddate 16/01/2019</strong> all records would be marked with an extra column showing Jan 2019 or something similar.</p>
<p>Additionally if there was a selection that spanned multiple months eg. <strong>01/01/2019 to 20/02/2019</strong> this would mark those relating to Jan and those relating to Feb in a new column?</p>
<p>Example of desired result:</p>

Create Query for getting value equals to Current User id | <p>I want to get all matching values with current user id from key "group_member". The key "group_member" consist of users id. Database screenshot:</p>
<p><a href="https://i.stack.imgur.com/pNqyx.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/pNqyx.png" alt="enter image description here"></a></p>
<p>For this, i create query <code>Query query = mGroupDatabase.child("group_member").equalTo(mCurrent_user_id);</code></p>
<p>but not getting any result.
afterwards, this result needs to shown into RecyclerView. </p>
<pre><code>mGroupList = (RecyclerView) mMainView.findViewById(R.id.group_list);
mAuth = FirebaseAuth.getInstance();
mCurrent_user_id = mAuth.getCurrentUser().getUid();
mGroupDatabase = FirebaseDatabase.getInstance().getReference().child("Groups");
LinearLayoutManager linearLayoutManager = new LinearLayoutManager(getContext());
linearLayoutManager.setReverseLayout(true);
linearLayoutManager.setStackFromEnd(true);
mGroupList.setHasFixedSize(true);
mGroupList.setLayoutManager(linearLayoutManager);
Query query = mGroupDatabase.child("group_member").equalTo(mCurrent_user_id);
query.keepSynced(true);

<p>in above code, <code>Log.d("sdfdfgghhjhj", group.getGroup_member());</code> doesnt give any value. </p>

<p>However, it doesn't provide this list with the response from the server. Only general data is displayed. I've tested and checked every article related to Alamofire, swiftyJSON, Swift .get requests and none of them works. </p>
<p>Considering this information: </p>
<ol>
<li>The connection with the server is being established (code)</li>
<li>If to launch the generated "shell" code and run through the "terminal"
(Mac OS) it returns the array.</li>
<li>Incorrect parsing? If yes - how to extract this data?</li>
</ol>
<p>Tried Dictionaries, swiftyJSON, NSSession ... but I did something wrong for sure. I'm dealing with JSON at SWIFT first time, so I can do silly mistakes!</p>
<p>Thanks to everyone who will try to help in advance!!!</p>

using animation_enabled boolean to prevent multiple jquery animations at once will break after being spammed | <p>I have 4 links on my page which fade their respective divs in and out as well as adjusting the containing div's height where necessary. I only want one div on a page at a time and the onload visible div is labels_div.</p>
<p>When the user spams these links the divs get out of sync or overlap each other. I have researched this and the best possible option is to use a boolean variable which is checked onclick of each link.</p>
<p>The issue arises that when a user spams the links eventually the boolean value gets stuck on false thus preventing any more animations.</p>
<p>Could somebody explain what I have done wrong? Thanks</p>

Kafka Connect in Docker container: Connector not added | <p>I'm trying to get a simple Kafka Connect container running. I did try the <a href="https://docs.confluent.io/5.0.0/installation/docker/docs/installation/connect-avro-jdbc.html" rel="nofollow noreferrer">Confluent Connect Tutorial</a>, but have a slightly different setup (no docker machine, no schema registry).</p>
<p>For the time being, I'm working with a Docker compose setup containing Zookeeper and Kafka.</p>
<pre><code>version: '3.1'
services:
zookeeper:
image: confluentinc/cp-zookeeper
ports:
- 2181
environment:
- ZOOKEEPER_CLIENT_PORT=2181
- ZOOKEEPER_TICK_TIME=2000
- ZOOKEEPER_SYNC_LIMIT=2
kafka:
image: confluentinc/cp-kafka
depends_on:
- zookeeper
ports:
- 9092
- 9094:9094
environment:
- KAFKA_ZOOKEEPER_CONNECT=zookeeper:2181
# setup :9092 for access inside the docker network, 9094 for outside (ie host)
- KAFKA_LISTENERS=INTERNAL://kafka:9092,OUTSIDE://kafka:9094
- KAFKA_ADVERTISED_LISTENERS=INTERNAL://kafka:9092,OUTSIDE://localhost:9094
- KAFKA_LISTENER_SECURITY_PROTOCOL_MAP=INTERNAL:PLAINTEXT,OUTSIDE:PLAINTEXT
- KAFKA_INTER_BROKER_LISTENER_NAME=INTERNAL
- KAFKA_OFFSETS_TOPIC_REPLICATION_FACTOR=1
- KAFKA_NUM_PARTITIONS=10
</code></pre>
<p>That works fine for different uses, so I don't expect this to be a problem.</p>
<p>Now I'm starting a Kafka Connect container which connects fine to Kafka. I use the following command which is adapted from the Connect Tutorial:</p>
<pre><code>docker run -d \
--name=kafka-connect-test \
--net=kafka-connect_default \
--expose 28083 \
-p 28083:28083 \
-e CONNECT_BOOTSTRAP_SERVERS=kafka:9092 \
-e CONNECT_REST_PORT=28083 \
-e CONNECT_GROUP_ID="quickstart-test" \
-e CONNECT_CONFIG_STORAGE_TOPIC="quickstart-test-config" \
-e CONNECT_OFFSET_STORAGE_TOPIC="quickstart-test-offsets" \
-e CONNECT_STATUS_STORAGE_TOPIC="quickstart-test-status" \
-e CONNECT_CONFIG_STORAGE_REPLICATION_FACTOR=1 \
-e CONNECT_OFFSET_STORAGE_REPLICATION_FACTOR=1 \
-e CONNECT_STATUS_STORAGE_REPLICATION_FACTOR=1 \
-e CONNECT_KEY_CONVERTER="org.apache.kafka.connect.storage.StringConverter" \
-e CONNECT_VALUE_CONVERTER="org.apache.kafka.connect.storage.StringConverter" \
-e CONNECT_INTERNAL_KEY_CONVERTER="org.apache.kafka.connect.storage.StringConverter" \
-e CONNECT_INTERNAL_VALUE_CONVERTER="org.apache.kafka.connect.storage.StringConverter" \
-e CONNECT_REST_ADVERTISED_HOST_NAME="localhost" \
-e CONNECT_LOG4J_ROOT_LOGLEVEL=DEBUG \
-e CONNECT_PLUGIN_PATH=/usr/share/java/kafka,/etc/kafka-connect/jars \
-v /tmp/quickstart/file:/tmp/quickstart \
-v /tmp/quickstart/jars:/etc/kafka-connect/jars \
confluentinc/cp-kafka-connect:latest
</code></pre>
<p>The most notable difference is that I'm using the <code>StringConverter</code>, because I'd like to use <code>kafkacat</code> to insert test data.</p>
<p>The container starts up fine and is running and reachable on all the exposed endpoints I tried.
Since I didn't add any connectors, I query the available ones:</p>
<p><code>localhost:28083/connector-plugins</code>:</p>
<pre><code>[
{
"class": "org.apache.kafka.connect.file.FileStreamSinkConnector",
"type": "sink",
"version": "5.4.0-ccs"
},
{
"class": "org.apache.kafka.connect.file.FileStreamSourceConnector",
"type": "source",
"version": "5.4.0-ccs"
},
{
"class": "org.apache.kafka.connect.mirror.MirrorCheckpointConnector",
"type": "source",
"version": "1"
},
{
"class": "org.apache.kafka.connect.mirror.MirrorHeartbeatConnector",
"type": "source",
"version": "1"
},
{
"class": "org.apache.kafka.connect.mirror.MirrorSourceConnector",
"type": "source",
"version": "1"
}
]
</code></pre>
<p>So for now it would be enough for me to create a file sink that writes data from a topic to a file. I POST to <code>localhost:28083/connectors</code></p>
<pre><code>{ "name": "file-sink",
"config": {
"connector.class": "org.apache.kafka.connect.file.FileStreamSinkConnector",
"tasks.max": 1,
"file": "/test.sink.txt",
"topics": "test-topic"
}
}
</code></pre>
<p>and receive <code>201 - Created</code>.</p>
<p>However, when querying that endpoint with <code>GET</code>, I get an empty array as a response. Trying around, I can also change the <code>connector.class</code> to <code>FileStreamSinkConnector</code> or just <code>FileStreamSink</code> and will still get a <code>201</code> (without a connector being added).</p>
<p>What am I doing wrong?</p>
<p>And why am I getting "success" responses when something obviously went wrong?</p> | 3 | 1,865 |

Why html player doesnt play audio blob on IOS safari? | <p>So I have two buttons(start/stop), canvas with sound visualizer and html5 audio player.
Everything works cool, but not on IOS Safari (tested on 15.3).
On IOS it shows that recording was started, that everything is going ok, but when the recording has stopped and blob inserted into audio tag, it shows "error" message inside audio-tag instead of playing this blob.
Here is the code:</p>
<pre><code> var stop = document.querySelector('#rec-stop');
var player = document.querySelector('#rec-player');
var totest = document.querySelector('.test-choice-btn');
navigator.mediaDevices.getUserMedia({audio:true})
.then(stream => {handlerFunction2(stream)})
function handlerFunction2(stream) {
rec = new MediaRecorder(stream);
audioContext = new AudioContext();
analyser = audioContext.createAnalyser();
microphone = audioContext.createMediaStreamSource(stream);
javascriptNode = audioContext.createScriptProcessor(2048, 1, 1);
analyser.smoothingTimeConstant = 0.8;
analyser.fftSize = 1024;
microphone.connect(analyser);
analyser.connect(javascriptNode);
javascriptNode.connect(audioContext.destination);
canvasContext = $("#rec-canvas")[0].getContext("2d");
javascriptNode.onaudioprocess = function() {
var array = new Uint8Array(analyser.frequencyBinCount);
analyser.getByteFrequencyData(array);
var values = 0;
var length = array.length;
for (var i = 0; i < length; i++) {
values += (array[i]);
}
var average = values / length;
canvasContext.clearRect(0, 0, 150, 270);
canvasContext.fillStyle = '#BadA55';
canvasContext.fillRect(0, 270 - average, 150, 270);
canvasContext.fillStyle = '#262626';
}
audioChunks = [];
rec.start();
stop.onclick = e => {

totest.classList.add('shown');
}

Unity game crash on some Android 6 (API 23) | <p>We have recently launched our android game ^_^ It it working fine for all users <strong>except for a few</strong>.</p>
<p>The has complained that it <strong>suddenly crashes in-game</strong>. We couldn't track or reproduce the issue but we know that they all have the same android version which is <strong>Android 6, API 23</strong>.</p>
<p>We tried running it on android 6 devices in our company but it just works fine.</p>
<p>I suspect it has something to do with something's version.</p>
<p>Any sort of idea?</p>
<blockquote>
<p>Unity version: 5.4.1f1</p>

How to save a nested many-to-many relationship in API-only Rails? | <p>In my Rails (api only) learning project, I have 2 models, Group and Artist, that have a many-to-many relationship with a joining model, Role, that has additional information about the relationship. I have been able to save m2m relationships before by saving the joining model by itself, but here I am trying to save the relationship as a nested relationship. I'm using the <a href="https://github.com/jsonapi-serializer/jsonapi-serializer" rel="nofollow noreferrer">jsonapi-serializer</a> gem, but not married to it nor am I tied to the JSON api spec. Getting this to work is more important than following best practice.</p>
<p>With this setup, I'm getting a 500 error when trying to save with the following errors:
<code>Unpermitted parameters: :artists, :albums</code> and <code>ActiveModel::UnknownAttributeError (unknown attribute 'relationships' for Group.)</code></p>
<p>I'm suspecting that my problem lies in the strong param and/or the json payload.</p>
<p><strong>Models</strong></p>
<pre><code>class Group < ApplicationRecord
has_many :roles
has_many :artists, through: :roles
accepts_nested_attributes_for :artists, :roles
end
class Artist < ApplicationRecord
has_many :groups, through: :roles
end
class Role < ApplicationRecord
belongs_to :artist
belongs_to :group
end
</code></pre>
<p><strong>Controller#create</strong></p>
<pre><code>def create
group = Group.new(group_params)
if group.save
render json: GroupSerializer.new(group).serializable_hash
else
render json: { error: group.errors.messages }, status: 422
end
end
</code></pre>
<p><strong>Controller#group_params</strong></p>
<pre><code>def group_params
params.require(:data)
.permit(attributes: [:name, :notes],
relationships: [:artists])
end
</code></pre>
<p><strong>Serializers</strong></p>
<pre><code>class GroupSerializer
include JSONAPI::Serializer
attributes :name, :notes
has_many :artists
has_many :roles
end
class ArtistSerializer
include JSONAPI::Serializer
attributes :first_name, :last_name, :notes
end
class RoleSerializer
include JSONAPI::Serializer
attributes :artist_id, :group_id, :instruments
end
</code></pre>
<p><strong>Example JSON payload</strong></p>
<pre><code>{
"data": {
"attributes": {
"name": "Pink Floyd",

How to create JS Canvas Top Down Rain Effect or Reverse Warp Speed | <p>I am trying to figure out how to create a canvas rain effect, but from the top down perspective. Basically it's like you are looking down at the ground and you are watching the rain fall around you and fall slightly to the center at an angle, but it falls a short distance before ending. I am not seeing anything in searches except some game development that isn't canvas.</p>
<p>I am also looking for a solution that doesn't require an external library.</p>
<p>I have been able to modify some warp speed effect code to reverse the direction on the particles to fall to the background instead of off screen, but it is continuing to infinity toward the center and not redrawing or looping the particles that are coming from off screen.</p>
<p>I think it has something to do with the particles not dropping off screen in this part of the code. Am I on the right track here or can I not accomplish this effect with the current code?</p>

different way to write a method | <p>I have a class to define a right hand side terms of differential equation:

<p><strong>EDIT</strong> thank for your answer so in my case it gonna be :</p>
<pre><code>foo_helper(foo &, int index);
operator()(int n, Type t, std::valarray<Type> u );

<p>right ?</p>
<p><strong>EDIT</strong> no I didn't get the point. I wrote :</p>
<pre><code>class dfdx {

void operator()(Type t, std::valarray<Type> u){

dfdx operator[](std::size_t index) {

<p>then I call it in this way : </p>
<pre><code>rhs.dfdx[j](t , uOld) )

How to judge bmp pictures from clipboard whether they are same using wxpython? | <p>Function that I want to realize:
when the bmp picture get from clipboard is changed, refresh window. If not, nothing will be done.</p>

every time my program goes into function UpdateMsgShownArea(), self.oldBmp will be diff with self.bmp, but I have already let self.oldBmp = self.bmp if they are different, and it prints "111111".

dynamic form funky behavior in vuejs | <p>I am using VueJS 2.6.11 and bootstrap 4 to create two dynamic sections(Category and Product) that contain divs and input fields. The product section is nested within the category section. When someone clicks the New Category button another category should get generated. The same behavior should also happen when someone clicks the New Product button, another Product section should get generated, but only inside the current category section.</p>
<p>Issue:</p>
<p>When someone clicks the New Product button, the Add Product section will get generated inside all current Category sections. Also, v-model appears to bind to every product name input. When someone clicks the X button for a specific Product section one product section would get deleted from all current Category sections.</p>
<p>I'm not exactly sure why this is happening.</p>

OpenCV corrupting HQ Rapsicam data above 4000x3040 resoution? | <h1>The Problem</h1>
<p>When I take an image using OpenCV that is larger than 4000 pixels wide, using a high quality picam, the image data appears corrupted (it's offset).</p>
<h2>More Detail</h2>
<p>As stated, I cannot get a good image when using OpenCV at over 4000 pixels wide of resolution. I know that the hardware is not the issue as I can get a clean full resolution (4056x3040) image when I use the raspistill command:</p>
<p><code>sudo raspistill -o testing.tiff -w 4056 -h 3040</code></p>
<p>Here is the clean output from raspistill:</p>
<p><a href="https://i.stack.imgur.com/EuE8o.jpg" rel="nofollow noreferrer">4056x3040 image - Clean Image produced by raspistill command</a></p>
<p>I am able to capture images using OpenCV in either Python:</p>
<pre><code>import cv2 as cv
def main():
cap = cv.VideoCapture("/dev/video2", cv.CAP_V4L2)
cap.set(cv.CAP_PROP_FRAME_WIDTH, 4056)#works fine up to 4000
cap.set(cv.CAP_PROP_FRAME_HEIGHT, 3040)
if not(cap.isOpened()):
print("could not open video device")
else:
print("cap opened")
ret, frame = cap.read()
if(ret):
cv.imwrite("./test_im.jpg", frame)
print("image saved")
else:
print("no capture data returned")
if __name__ == "__main__":
main()

<p>The Result is the same either way.</p>
<p>Here is the corrupted output from OpenCV:</p>

<p>To me it seems as if it something was going wrong with the timing of the capture. The format of which I save it to does not make a difference either. I have tried .png, .jpg, and .tiff. The result is always the same. After reboot the results remain the same.</p>
<p>If I reduce the desired capture resolution to only 4000x3040 then I am able to successfully make a capture. Here are the results:</p>
<p><a href="https://i.stack.imgur.com/1BMdC.jpg" rel="nofollow noreferrer">4000x3040 image - successfully captured by OpenCV</a></p>
<p>I am not sure why this is happening. And would really appreciate any help! Let me know if there is any other information that could be useful!</p>

How do I use SELECT LAST_INSERT_ID() without closing the connection | <p>I have table whose only column is an auto-incrementing primary key. I want to insert a new row into this table, and then get the ID generated by this insert. </p>
<p>Reading through StackOverflow, LAST_INSERT_ID() appears to be the standard solution. The caveat given is that it will return the last generated ID per connection. I wrote a new method to INSERT and then SELECT, all without closing the connection. Then I started getting "Operation not allowed after ResultSet closed" errors. Reading up on that in StackOverflow leads me to think I should not be preparing multiple statements on the same connection. </p>
<p>How should I be implementing this insert and select model? Am I misunderstanding what counts as the database connection concerning LAST_INSERT_ID()?</p>
<p>relevant excerpts:</p>

StringBuilder stmt2 = new StringBuilder("SELECT LAST_INSERT_ID()");
ResultSet resultSet = MysqlPortal.specialExecuteStatement(stmt.toString(), parameters, stmt2.toString());
if (resultSet.next()) {
returnConceptID = new ConceptID(resultSet.getLong(1));
resultSet.getStatement().close();

Fail to load ApplicationContext SpringBoot with SpringSecurity and JUnit Jupiter | <p>I'm working on a REST API using Spring Boot. Currently, the V1 of the API is complete. So, I'm implementing Spring Security to manage authentication and authorization.<br />
Since I've implemented Spring Security, my JUnit Jupiter tests does not work (no one works).</p>
<p>I searched a lot a solution on internet, but all answers I found are for JUnit4 and not JUnit5 (so I don't have all required classes).<br />

How to serialize json to sql? | <p>I have a list of words and I should send requests to an API and get the information about the words.

<p>I watched <a href="https://www.youtube.com/watch?v=wv5VFEcnb-8" rel="nofollow noreferrer">this video</a>, which made it seem sort of simple, but it is referring to Kotlin and my code is not far off.</p>
<p><a href="https://stackoverflow.com/questions/56219768/toolbars-back-button-not-working-when-using-with-navigation-drawer">This post</a> covers a similar challenge as well, though in Kotlin I tried adding a setNavigationOnClickListener and put a logd statement in it. It never got fired, but the solution itself seemed like it shouldn't be necessary.</p>
<p><a href="https://stackoverflow.com/questions/60030589/how-to-make-up-button-go-back-instead-of-opening-navigation-drawer">This post</a> seems to have cover the same issue but there are no answers. One of the responses says to setupActionBarWithNavController, which I have:</p>
<pre><code>NavigationUI.setupActionBarWithNavController(this, navController, appBarConfiguration);
</code></pre>
<p>This function has a lot of overloads and I've tried a number of them, but they seem to cause me to lose the set of top level destinations (hamburger icon for multiple fragments) and undue my the navigation which is working.</p>
<p>I tried to follow <a href="https://developer.android.com/guide/navigation/navigation-ui#add_a_navigation_drawer" rel="nofollow noreferrer">this documentation</a>, but it only seemed to step me back from where I was. This call:</p>
<pre><code> AppBarConfiguration appBarConfiguration =
new AppBarConfiguration.Builder(navController.getGraph())
.setDrawerLayout(drawerLayout)
.build();
</code></pre>
<p>Seems to replace the topLevelDestinations and use the navController.getGraph(), but since I have multiple ones, I have been referencing the <a href="https://developer.android.com/guide/navigation/navigation-ui#appbarconfiguration" rel="nofollow noreferrer">fragments themselves</a>.</p>
<p>I did <a href="https://stackoverflow.com/questions/63525227/navigation-drawer-hamburger-menu-working-but-back-arrow-opens-the-drawer">ask</a> about this problem previously but it was clear to me I did not explain it well (answers addressed how to pop back and not why the back arrow was not working). I would have deleted it but people did answer and the guidance SO provided was that I should not delete it in that case. I am sorry if I caused confusion.</p> | 3 | 1,364 |
Distribute values across subsequent rows in Postgresql | <p>I have two tables. One contains user state transitions.</p>
<pre><code>create table state (
id serial primary key,
ctime timestamp with time zone not null,
state text not null
);
insert into state (ctime, state) values
('2019-05-01 03:58:40+00', 'Busy')
, ('2019-05-01 03:58:42+00', 'Ready')
, ('2019-05-01 04:00:14+00', 'Busy')
, ('2019-05-01 04:16:26+00', 'Ready')
, ('2019-05-01 04:16:36+00', 'Busy')
;
</code></pre>
<p>And the other one contains user's actions.</p>
<pre><code>create table action (
id serial primary key,
ctime timestamp with time zone not null,
action text not null
);
insert into action (ctime, action) values
('2019-05-01 03:58:42+00', 'vasah')
, ('2019-05-01 03:58:42+00', 'mituh')

order by ctime;

Python Tkinter: Create a variable for each string inside a listbox? | <p>I'm (almost) a poor programmer-virgin so please go easy on me.</p>
<p>This is my second attempt at making a program and this is turning out to be a bit more than I can navigate, I am afraid. I ask for your help after a long time of trying to solve this.</p>
<p>I am basically making a ToDo-list but wanted it to have some more functionality than just being a boring list.</p>
<p>How I imagine it in my head is that the user adds a task into an entry widget, which would then be displayed in a Listbox. Each string in the Listbox would then have a value associated with it (which I need to some calculations for the functionality I want the program to have).
So what I think I kind of want is every string in the Listbox to be made a variable and then associated with that variable I want a value.</p>
<p>I will try to show you:</p>
<p>Here I am adding the string that I want to become a new variable</p>
<p><a href="https://i.stack.imgur.com/0aKiZ.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/0aKiZ.jpg" alt="Adding the string" /></a></p>
<p>Then I specify a number from a drop down menu. I want this number to be the value of the variable/string from previous step.</p>
<p><a href="https://i.stack.imgur.com/SuHsh.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/SuHsh.jpg" alt="Value that must be designated to the variable/string" /></a></p>
<p>I really hope one of you can lead me in the right direction in a way that (preferably) doesn't require me to change things up too much. Things are still very slippery to me and it is already fairly hard for me to navigate the code.
The purpose is simply that I want to do some calculations with the (hopefully) soon-to-be values associated with each task.
Thanks in advance if any of you dare!</p>

WPF Custom DependencyProperty Binding - SetValue set correct value but binded property set receive null | <p>I have issue with custom DependencyProperty in my control. Let me explain:</p>
<p>I have control with list of the checkable items. I need property binding to the IEnumerable SelectedItems. The logic of SelectedItemsProperty filling is inside of control, so it is not just simple binding. Here is code behind of my control:</p>
<pre><code> public static readonly DependencyProperty SelectedItemsProperty = DependencyProperty.Register("SelectedItems", typeof(IEnumerable<object>), typeof(ButtonColumnFilter));
public IEnumerable<object> SelectedItems
{
get { return (IEnumerable<object>)GetValue(SelectedItemsProperty); }
set { Debug.WriteLine("SelectedItems has been set in ButtonColumnFilter - Count:{0}", value?.Count());
SetValue(SelectedItemsProperty, value);
}
}
</code></pre>
<p>Here I get Debug message with correct number of selected items, so my logic inside of control is working well. The property in XAML is binded here:</p>
<pre><code> <MESControls:ButtonColumnFilter CanSearch="True" CanSort="False" DisplayMemberPath="DisplayName"
ItemsSource="{Binding Path=FilterAdapter.Drivers, Mode=OneWay, IsAsync=True}"
OnApplyFilter="Drivers_ApplyFilter"
SelectedItems="{Binding Path=SelectedFilterDrivers, Mode=TwoWay}"/>
</code></pre>
<p>And property is defined in my code here:</p>
<pre><code>public IEnumerable<Driver> SelectedFilterDrivers
{
get => _SelectedFilterDrivers;
set
{
Debug.WriteLine("SelectedFilterDrivers has been set in PlannerFilterAdapter - Count: {0}", value?.Count());
if (_SelectedFilterDrivers != value)
{
_SelectedFilterDrivers = value;
NotifyPropertyChanged("SelectedFilterDrivers");
}
}
}

<p>!!! But here I get Debug message 'value == null' !!!</p>
<p>The binding is working well, and property set is called correctly in time i suppose. The weird is, that SetValue inside control has correct value, but outside in code the propert set value is null.</p>
<p>What can be wrong?
Thanks.</p>
<p>UPDATE:</p>
<p>Here is code that changes SelectedItems inside control:</p>
<pre><code>private void CheckableItem_PropertyChanged(object sender, PropertyChangedEventArgs e)
{
if (e.PropertyName == "IsChecked" && !_IsChecking)
{
_IsChecking = true;
CheckableItem item = sender as CheckableItem;
if(item.IsChecked == true && InnerItemsSource.Where(ci=>ci.Item.ToString() != SELECTALL).All(ci=>ci.IsChecked == true))
{
InnerItemsSource.Single(ci => ci.Item.ToString() == SELECTALL).IsChecked = true;
SelectAllIsSelected = true;
}
else if (InnerItemsSource.Where(ci => ci.Item.ToString() != SELECTALL).All(ci=>ci.IsChecked == true) || InnerItemsSource.Where(ci => ci.Item.ToString() != SELECTALL).All(ci => ci.IsChecked == false))
{
InnerItemsSource.Single(ci => ci.Item.ToString() == SELECTALL).IsChecked = false;
SelectAllIsSelected = false;
}
else
{
InnerItemsSource.Single(ci => ci.Item.ToString() == SELECTALL).IsChecked = null;
SelectAllIsSelected = false;
}
SelectedItems = CheckedItems;
NotifyPropertyChanged("IsFilterUsed");
NotifyPropertyChanged("FilterIcon");
}
_IsChecking = false;
}
public IEnumerable<object> CheckedItems
{
get
{
return InnerItemsSource?.Where(ci => ci.IsChecked == true && ci.Item.ToString() != SELECTALL).Select(ci => ci.Item);
}
}
</code></pre>
<p>But as I written, the property set inside control receive correct value and I guess correct type. The return value of CheckedItems is IEnumerable'<<em>object</em>>'.</p>
<p>Thanks for help.</p>

The true is, that between theses steps is some external code - but I didn't get any error neither warning

<p>UPDATE - some progress</p>
<p>I tried change public IEnumerable<<em>Driver</em>> SelectedFilterDrivers to </p>
<pre><code>public IEnumerable<object> SelectedFilterDrivers
{
get => _SelectedFilterDrivers;
set
{
Debug.WriteLine("SelectedFilterDrivers has been set in PlannerFilterAdapter - Count: {0}", value?.Count());
if (_SelectedFilterDrivers != value)
{
_SelectedFilterDrivers = (IEnumerable<Driver>)value;
NotifyPropertyChanged("SelectedFilterDrivers");
}
}
}
</code></pre>
<p>And I receive correct number of items. So there is an issue during retyping of items in collection. So I need to kick forward with the better way, how to keep ability for SelectedItems to use generic IEnumerable<<em>object</em>> </p>
<p>Important is, that IEnumerable<<em>object</em>> is working well with simple binding (in this case ItemsSource - true is, that it si just OneWay binding)</p> | 3 | 2,624 |

How to pass 'quotaUser' parameter for queries to MySQL server in GCP from cloud function? | <p>I'm working on a project right now that shows a list of items. To retrieve this data, the page calls a callable cloud function which queries the data from a MySQL server. This MySQL server, like our cloud functions, is part of our project on the Google Cloud Platform.</p>
<p>The page that shows the items is used quite a lot by our customer and last Tuesday they reported some problems that the data wasn't showing or took a long time to show up.
Having looked at the cloud function logs at that time, we see a lot of timeouts followed by a few of these errors:</p>
<blockquote>
<p>CloudSQL warning: your action is needed to update your function and avoid potential disruptions. Please see <a href="https://cloud.google.com/functions/docs/sql#troubleshooting" rel="nofollow noreferrer">https://cloud.google.com/functions/docs/sql#troubleshooting</a> for additional details: googleapi: Error 429: Quota exceeded for quota group 'default' and limit 'Queries per user per 100 seconds' of service 'sqladmin.googleapis.com' for consumer 'project_number:[some number]'., rateLimitExceeded</p>
</blockquote>
<p>I'm not entirely sure if this is the cause of the issue, but it does seem like something we should do something about anyway.
As I understand it, we can send 300 queries per user per 100 seconds to the MySQL server. So about 3 per second. The cloud function itself only sends 2 queries to the server. One to retrieve the data for the current page with the applied filters and another one to get a total record count.
However, we don't send any user info when performing the query. So I think that if 150 users each trigger the callable, 300 queries will be performed and counted towards the quota as if they were done by a single user. Because it's a server, the cloud function, that actually performs the query. The error also mentions the quota group 'default'.</p>
<p>The following page tells me that I should be able to pass a 'quotaUser' parameter to specify a specific user that requests should count towards for the quota.</p>
<p><a href="https://cloud.google.com/apis/docs/capping-api-usage#limiting_requests_per_second_per_user" rel="nofollow noreferrer">https://cloud.google.com/apis/docs/capping-api-usage#limiting_requests_per_second_per_user</a></p>
<p>However... I have no idea how to pass that parameter with our queries. I've read something that this parameter can be used in the url parameters or in the headers, but we are using the Node.js mysql package to perform these queries, and I don't know how to tell it to send this parameter.
This is the guide we followed to set up the mysql connection. We are using the same mysql package.</p>
<p><a href="https://cloud.google.com/sql/docs/mysql/connect-functions#node.js" rel="nofollow noreferrer">https://cloud.google.com/sql/docs/mysql/connect-functions#node.js</a></p>
<p>I would think that if a GCP guide tells us to use that mysql package, it should also somehow be possible to specify this quotaUser.</p>
<p>If anyone can help me out with this, it would be greatly appreciated. I'm a bit stuck and can't find any documentation or examples on how to pass this parameter for MySQL queries.</p>
<p>This is how we connect to the MySQL server:</p>
<pre><code>import { config } from '../config';
import { createConnection, Connection, ConnectionConfig } from 'mysql';
export function connectToMySQLDatabase(): Connection {
const connectionName: string | undefined = process.env.INSTANCE_CONNECTION_NAME || `${config.firebaseProjectId}:${config.mysqlConfig.regionId}:${config.mysqlConfig.instanceId}`;
const dbUser: string | undefined = process.env.SQL_USER || config.mysqlConfig.user;
const dbPassword: string | undefined = process.env.SQL_PASSWORD || config.mysqlConfig.password;
const dbName: string | undefined = process.env.SQL_NAME || config.mysqlConfig.databaseName;
const mysqlConfig: ConnectionConfig = {
user: dbUser,
password: dbPassword,
database: dbName,
dateStrings: true,
socketPath = `/cloudsql/${connectionName}`;
};
return createConnection(mysqlConfig);
}
</code></pre>
<p>And how we perform a query:</p>
<pre><code>exports.itemQuerySQL = functions
.region(config.region)
.runWith({
timeoutSeconds: 60,
memory: '1GB'
})
.https
.onCall(async (request: GetItemsRequest, context) => {
const mysqlConnection: Connection = connectToMySQLDatabase();
try {
return await queryItems(request, mysqlConnection);
} catch (error) {
throw error;
}
finally {
mysqlConnection.end();
}
});
async function queryItems(request: GetItemsRequest, mysqlConnection: Connection): Promise<CallableQueryResponse<string>> {
let query = '';
let values = [];
// Removed a bunch of code irrelevant to the issue that builds up the query and values array.
const results: any[] = await performQuery(mysqlConnection, sqlQuery, sqlQueryValues);
return {
results: results,
// Some other properties
};
}
async function performQuery(mysqlConnection: Connection, query: string, values?: (string | string[] | number | null)[]): Promise<any> {
return new Promise((resolve: (value?: unknown) => void, reject: (reason?: any) => void): void => {
mysqlConnection.query(query, values, (error: MysqlError, results: any) => {
if (error) {
return reject(error);
} else {
return resolve(results);
}
});
});
}
</code></pre>
<p>Besides the code that constructs the query itself, I also left out most of the error handling to keep these examples small.</p> | 3 | 1,792 |

Using CUDA atomicInc to get unique indices | <p>I have CUDA kernel where basically each thread holds a value, and it needs to add that value to one or more lists in shared memory. So for each of those lists, it needs to get an index value (unique for that list) to put the value.</p>
<p>The real code is different, but there are lists like:</p>
<pre><code>typedef struct {
unsigned int numItems;
float items[MAX_NUM_ITEMS];
} List;
__shared__ List lists[NUM_LISTS];
</code></pre>
<p>The values <code>numItems</code> are initially all set to 0, and then a <code>__syncthreads()</code> is done.</p>
<p>To add its value to the lists, each thread does:</p>
<pre><code>for(int list = 0; list < NUM_LISTS; ++list) {
if(should_add_to_list(threadIdx, list)) {
unsigned int index = atomicInc(&lists[list].numItems, 0xffffffff);
assert(index < MAX_NUM_ITEMS); // always true
lists[list].items[index] = my_value;
}
}
</code></pre>
<p>This works most of the time, but it seems that when making some unrelated changes in other parts of the kernel (such as not checking asserts that always succeed), sometimes two threads get the same index for one list, or indices are skipped.
The final value of <code>numSamples</code> always becomes correct, however.</p>
<p>However, when using the following custom implementation for <code>atomicInc_</code> instead, it seems to work correctly:</p>
<pre><code>__device__ static inline uint32_t atomicInc_(uint32_t* ptr) {
uint32_t value;
do {
value = *ptr;
} while(atomicCAS(ptr, value, value + 1) != value);
return value;
}
</code></pre>
<p>Are the two <code>atomicInc</code> functions equivalent, and is it valid to use <code>atomicInc</code> that way to get unique indices?</p>
<p>According the the <a href="https://docs.nvidia.com/cuda/cuda-c-programming-guide/#atomic-functions" rel="nofollow noreferrer">CUDA programming guide</a>, the atomic functions do not imply memory ordering constraints, and different threads can access the <code>numSamples</code> of different lists at the same time: could this cause it to fail?</p>
<p><strong>Edit:</strong></p>
<p>The real kernel looks like this:</p>
<p>Basically there is a list of <em>spot blocks</em>, containing <em>spots</em>. Each <em>spot</em> has XY coordinates (<em>col</em>, <em>row</em>). The kernel needs to find, for each spot, the spots that are in a certain window (col/row difference) around it, and put them into a list in shared memory.</p>
<p>The kernel is called with a fixed number of warps. A CUDA block corresponds to a group of <em>spot blocks</em>. (here 3) These are called the <em>local</em> spot blocks.</p>
<p>First it takes the spots from the block's 3 spot blocks, and copies them into shared memory (<code>localSpots[]</code>).
For this it uses one warp for each spot block, so that the spots can be read coalesced. Each thread in the warp is a spot in the local spot block.
The spot block indices are here hardcoded (<code>blocks[]</code>).</p>
<p>Then it goes through the <em>surrounding</em> spot blocks: These are all the spot blocks that may contain spots that are close enough to a spot in the <em>local spot blocks</em>. The surrounding spot block's indices are also hardcoded here (<code>sblock[]</code>).</p>
<p>In this example it only uses the first warp for this, and traverses <code>sblocks[]</code> iteratively. Each thread in the warp is a spot in the surrounding spot block.
It also iterates through the list of all the local spots. If the thread's spot is close enough to the local spot: It inserts it into the local spot's list, using <code>atomicInc</code> to get an index.</p>
<p>When executed, the printf shows that for a given local spot (here the one with row=37, col=977), indices are sometimes repeated or skipped.</p>
<p>The real code is more complex/optimized, but this code already has the problem. Here it also only runs one CUDA block.</p>

<p>Each line is the output of one execution (the kernel is run multiple times). It is expected that indices appear in different orders. But for example on the third-last line, index 23 is repeated.</p>
<p>Using <code>atomicCAS</code> seems to fix it. Also using <code>__syncwarp()</code> between executions on the outer for-loop seems to fix it. But it is not clear why, and if that always fixes it.</p>

Data Validation should be pulling based off of previous Options. Returning Undefined | <p>The Bid Sheet is ultimately supposed to enable the user to enter the various Options and it will give them a list if Items with those Options. I suspect my attempt to use the same scripting as the single validation Option is insufficient to handle the multiple Options, but I am too inexperienced to know a better path.</p>
<p>Everything works except for this piece. Which returns "undefined".</p>

Client server authentication with self signed certificate - Curl is working but Apache HttpClient throws exception | <p>I'm trying to implement client and server authentication with Apache HTTPClient,
and to test it with a self signed certificate.
I've tried to follow several tutorials and answers to similar questions here but
with no success. I've tried to detail as much as possible all the steps that I've
been doing, hopefully someone can point out what I'm doing wrong:</p>
<ol>
<li><p>Created a file <code>req.conf</code> for configuration</p>
<pre><code>[req]
prompt=no
distinguished_name = req_distinguished_name
[ req_distinguished_name ]
O=selfSignedO
CN=selfSignedCn
DC=selfSignedDc
</code></pre></li>
<li><p>Generated server private key and the self-signed certificate</p>
<pre><code>openssl req \
-config req.conf \
-x509 \
-newkey rsa:4096 \
-keyout server/server-private-key.pem \
-out server/server.crt \
-days 3650 \
-nodes
</code></pre></li>
<li><p>Created PKCS12 keystore containing the private key and certificate created in the previous step</p>
<pre class="lang-sh prettyprint-override"><code> openssl pkcs12 \
-export \
-out server/server-key-store.p12 \
-inkey server/server-private-key.pem \
-in server/server.crt
</code></pre>
<p>let's say the password I used was <code>123456</code></p></li>
<li><p>Generated a client private key and a certificate signing request</p>
<pre class="lang-sh prettyprint-override"><code>openssl req \
-config req.conf \
-new \
-newkey rsa:4096 \
-out client/client-request.csr \
-keyout client/client-private-key.pem \
-nodes
</code></pre></li>
<li><p>Signed the client's certificate signing request with the server's private key
and certificate</p>
<pre class="lang-sh prettyprint-override"><code>openssl x509 \
-req \
-days 360 \
-in client/client-request.csr \
-CA server/server.crt \
-CAkey server/server-private-key.pem \
-CAcreateserial \
-out client/client-signed-cert.crt \
-sha256
</code></pre></li>
<li><p>Created a PKCS12 keystore containing the client's private key and certificate certificate created in the previous step.</p>
<pre class="lang-sh prettyprint-override"><code> openssl pkcs12 \
-export \
-out client/client-keystore.p12 \
-inkey client/client-private-key.pem \
-in client/client-signed-cert.crt \
-certfile server/server.crt
</code></pre>
<p>we used <code>123456</code> as password again.</p></li>
<li><p>Generated server trust store containing the client signed certificate</p>
<pre class="lang-sh prettyprint-override"><code>keytool \
-import \
-trustcacerts \
-alias root \
-file client/client-signed-cert.crt \
-keystore server/server-trust-store.jks
</code></pre>
<p>password? <code>123456</code></p></li>
<li><p>Curl is working, but only with <code>-k</code></p>
<pre class="lang-sh prettyprint-override"><code>curl -k \
--cert client/client-signed-cert.crt \
--key client/client-private-key.pem \
https://localhost:443:/my/endpoint
</code></pre>
<p>without the <code>-k</code> I get the error:</p>
<pre class="lang-sh prettyprint-override"><code>curl: (60) SSL certificate problem: self signed certificate
More details here: https://curl.haxx.se/docs/sslcerts.html
curl performs SSL certificate verification by default, using a "bundle"
of Certificate Authority (CA) public keys (CA certs). If the default
bundle file isn't adequate, you can specify an alternate file
using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
the bundle, the certificate verification probably failed due to a
problem with the certificate (it might be expired, or the name might
not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
the -k (or --insecure) option.
HTTPS-proxy has similar options --proxy-cacert and --proxy-insecure.
</code></pre></li>
<li><p>Configured Apache HTTPClient:</p>
<pre class="lang-java prettyprint-override"><code>private HttpClient createClient() throws Exception {
String keyPassword = "123456";
KeyStore ks = KeyStore.getInstance("PKCS12");
ks.load(resourceAsStream("/client/client-key-store.p12"), keyPassword.toCharArray());
SSLContext sslContext = new SSLContextBuilder()
.setProtocol("TLSv1.2")
.loadKeyMaterial(ks, keyPassword.toCharArray())
.loadTrustMaterial(null, new TrustSelfSignedStrategy())
.build()
return HttpClients.custom()
.setSSLContext(sslContext)
.setSSLHostnameVerifier(new NoopHostnameVerifier())
.build();
}
</code></pre>
<p>(The construction is done via multiple methods that I squeezed here to one, so if something is weird or missing please let me know, perhaps I miscopy-pasted something.) </p></li>
</ol>
<p>but when trying to send the same request as with Curl I'm getting:</p>

Different types JSON file using ObjectMapper | <p>I am using AlamofireObjectMapper to communicate with a backend server. The result of one of the requests is an array of items, which contain two values:</p>
<ul>
<li>A "typeIdentifier" indicating which type of data the second value ("arbitraryData") is of</li>
<li>A "arbitraryData":
<ul>
<li>If "typeIdentifier" CONTAINS "X", arbitraryData is of type ArbitraryDataTypeX</li>
<li>If "typeIdentifier" CONTAINS "Y", arbitraryData is of type ArbitraryDataTypeY</li>
</ul></li>
</ul>
<p>The two ArbitraryDataType classes do not share any common ancestor (except Mappable). It could be even a primitive type, an array, an optional, etc.</p>
<p>How can I make AlamofireObjectMapper parse the "arbitraryData" field using the appropriate type.</p>
<p>See the following JSON file:</p>
<pre><code>{
"arrayOfItems": [
{
"typeIdentifier": "X",
"arbitraryData":
{
"value": "BLA",
}
},
{
"typeIdentifier": "Y",
"arbitraryData":
{
"anotherValue": "BLUBB",
}
}
]
}
</code></pre>
<p>My corresponding Swing file looks like the following:</p>
<pre><code>class Item : Mapping {
var typeIdentifier = "X"
var arbitraryData: Mappable? = nil
init?(_ map: Map) {
self.init()
mapping(map)
}
func mapping(map: Map) {
typeIdentifier <- map["typeIdentifier"]
// THIS LINE CONTAINS MY QUESTION: HOW CAN I TELL OBJECTMAPPER, THAT,
// IF typeIdentifier CONTAINS "X", arbitraryData IS OF TYPE
// ArbitraryDataTypeX, AND IF "Y" arbitraryData IS OF TYPE
// ArbitraryDataTypeY?
arbitraryData <- map["arbitraryData"]
}
}
class ArbitraryDataTypeX : Mapping {
var value = "BLA"
init?(_ map: Map) {
self.init()
mapping(map)
}
func mapping(map: Map) {
value <- map["value"]
}
}
class ArbitraryDataTypeY : Mapping {
var anotherValue = "BLUBB"
init?(_ map: Map) {
self.init()
mapping(map)
}
func mapping(map: Map) {
anotherValue <- map["anotherValue"]
}
}
</code></pre>
<p>Background information: I am using AlamofireObjectMapper to communicate with a backend server. The result of one of the requests is an array of Item. The typeIdentifier-mechanism (infact it is a little bit more complex, but let's leave this out) is given by the backend and cannot be changed.</p> | 3 | 1,058 |

How to run DatabaseUtil.precomputedKNNQuery method of LOF class on two different threads | <p>I want to reduce runtime of DatabaseUtil.precomputedKNNQuery method by running this method on two different threads and KNNQuery is an interface.</p>
<pre><code> KNNQuery<O> knnq = DatabaseUtil.precomputedKNNQuery(database, relation, getDistanceFunction(), k);
</code></pre>
<p>I divided this method of LOF class in two parts like this</p>
<pre><code> Callable<KNNQuery> task1(Database database, Relation<O> relation){
DBIDs idss = relation.getDBIDs();
ArrayDBIDs aids = (ArrayDBIDs) idss;
aids = aids.slice(0, (aids.size() / 2));
aids.size();
ProxyView<O> pv = new ProxyView<>(aids, relation);
return () -> {
return DatabaseUtil.precomputedKNNQuery(database, pv,
getDistanceFunction(), k);
};
}
Callable<KNNQuery> task2(Database database, Relation<O> relation) {
DBIDs idss = relation.getDBIDs();
ArrayDBIDs aids = (ArrayDBIDs) idss;
aids = aids.slice(((aids.size() / 2) - 1), aids.size());
aids.size();
ProxyView<O> pv2 = new ProxyView<>(aids, relation);
return () -> {
return DatabaseUtil.precomputedKNNQuery(database, pv2, getDistanceFunction(), k);
};
}
</code></pre>
<p>Then i invoked both these tasks on two different threads like this in run() method of LOF class </p>
<pre><code> public OutlierResult run(Database database, Relation<O> relation) {
StepProgress stepprog = LOG.isVerbose() ? new StepProgress("LOF", 3) : null;
DBIDs ids = relation.getDBIDs();
LOG.beginStep(stepprog, 1, "Materializing nearest-neighbor sets.");
ExecutorService executor = Executors.newFixedThreadPool(2);
List<Callable<KNNQuery>> callables = Arrays.asList(
task1(database, relation),
task2(database, relation));
for (Future<KNNQuery> future : executor.invokeAll(callables)) {
KNNQuery<O> knnq = future.get();
// Compute LRDs
// compute LOF_SCORE of each db object
// Build result representation
}
}
</code></pre>
<p>But i am getting exception which is saying something like this because forEach is providing only output of first future in knnq variable but not the combined output of both future's. Please help me how can i get rid of this exception with example thanks?</p>

JPA Hibernate Configuration Errors | <p>I want to enable JPA for an EJB module, in an IntelliJ J2E project. I don't have an existing database schema to import; I want to generate the schema and tables from my EJB POJO class. I then want to generate ORM mappings.</p>
<p>I've enabled JavaEE Persistence framework support in IntelliJ, with Hibernate as the provider. I've updated persistence.xml and assigned MySQL@localhost as the data source, to the JPA persistence unit. I've also added the JPA descriptor to the ear artifact.</p>
<p>When I try to add the JPA annotations to my POJO, e.g. @Table, @Column etc, I get an error "Cannot resolve table 'TABLE_NAME'"...same applies for columns. The context action I get is 'Assign Data Sources', but the data source is showing as assigned to the persistence unit.</p>
<p>I've run the code and now just get a huge stack trace.</p>
<p>The tutorials i've found are either for importing an existing schema (which I don't have), or use other IDEs. My persistence.xml and one of my pojos are included below</p>
<p>Thanks in advance..</p>
