37,534,548 | How to access a gmail account I own using Gmail API? | <p>I want to run a node script as a cronjob which uses Gmail's API to poll a gmail account I own.</p>

<p>I'm stuck on the first step. When requesting credentials for a cron script it tells me that "User data cannot be accessed from a platform without a UI because it requires user interaction for sign-in":</p>

<p>The docs are confusing in general, and mention "service accounts," "OAuth," and other things -- I cannot tell which apply to my use-case and which don't. I've used many SaaS APIs, and the typical workflow is to login to your account, get an API key and secret, and use those in your script to access the API. It seems this is <em>not</em> the paradigm used by the Gmail API, so I'd appreciate any guidance or links to clearer instructions.</p>

37,535,241 | Generating A List of Possible Moves | I am trying to generate a list of possible moves for a checkers-like game. For example, at the start of the game the board would look like [[1,1,1], [0,0,0], [2,2,2]]. My function would take the color (one for white, or two for black) and move the pieces either one space forward, or one space diagonal to capture another piece. So the first possible list of moves with white going first would be [[0,1,1], [1,0,0], [2,2,2], [1,0,1], [0,1,0, [2,2,2] etc. etc.
So far I have:
def generateMoves(color, board):
newboard = []
subboard = []
board = [[1, 1, 1], [0, 0, 0], [2, 2, 2]]
x = 0
for i in board:
while x < len(board):
subboard.append(board[x])
newboard.append(subboard)
x += 1
return newboard
but I can't figure out what modifications I need to make to it to calculate the new list of possible moves. | <python> | 2016-05-31 00:43:14 | LQ_EDIT |

37,540,616 | Do we have any possibility to stop request in OkHttp Interceptor? | <p>In our app we met with one special case - if our <code>App.specialFlag == true</code>, we need stop any request from our code. And we think, that the best approach in this situation is include special <code>Interceptor</code> which will stop any our requests, something like this:</p>
<pre><code>if (App.specialFlag) {
// Somehow stop request
} else {
return chain.proceed(chain.request());
}
</code></pre>
<p>Also, we should note, that we use <code>RxJavaCallAdapterFactory</code> for wrapping responses into <code>Observable</code>s.</p>
<p>But we don't see any methods for stopping request in OkHttp Interceptors. </p>
<p>We came up with two ways to solve our issue:</p>
<p>a) Create special <code>ApiService.class</code> for wrapping every request in our API like this:</p>
<pre><code>public Observable<User> getUserDetails() {
if (App.specialFlag) {
return Observable.just(null);
}
return api.getUserDetails();
}
</code></pre>
<p>But we think that it is ugly and cumbersome solution.</p>
<p>b) Throw a <code>RuntimeException</code> in Interceptor, then catch it in every place we use our API. </p>
<p>The second solution is also not good, because we need to include a lot of <code>onErrorResumeNext</code> operators in our chains.</p>
<p>May be someone knows, how to handle our situation in more 'clever' way?..</p>

37,544,410 | sonar-maven-plugin: extending sonar.sources in multi-module project | <p>I want to extend <code>sonar.sources</code>, which by default is <code>pom.xml,src/main/java</code>, by <code>src/main/resources</code> in order to check XML files that are located there.</p>
<p>This seemingly simple task turned out to be difficult since I have a multi-module maven project (> 100 modules, nested) with a lot of them don't have a <code>src/main/resources</code> folder and most of them not even a <code>src</code> folder (e.g. for packaging=pom). This leads to a build error if I set <code>sonar.sources</code> to <code>pom.xml,src/main/java,src/main/resources</code> or <code>pom.xml,src/main</code>:</p>
<pre><code>[ERROR] Failed to execute goal org.codehaus.mojo:sonar-maven-plugin:2.5:sonar (default-cli) on project xyz-parent: The directory 'C:\...\submodule\src\main\resources' does not exist for Maven module ... Please check the property sonar.sources -> [Help 1]
</code></pre>
<p>The sonar-maven-plugin itself uses <code>${project.build.sourceDirectory}</code> to do it right in every module.</p>
<p>I tried to use regular expressions to set <code>sonar.sources</code> to <code>src/main</code> by cutting off <code>/java</code> (or <code>\java</code> on Windows) via</p>
<pre><code><plugin>
<groupId>org.codehaus.mojo</groupId>

<regex>[/\\]+java$</regex>
<replacement></replacement>
<failIfNoMatch>false</failIfNoMatch>
</configuration>
</execution>
</executions>
</plugin>
</code></pre>
<p>But this does nothing and I have no idea to which lifecycle phase I should bind it to have it executed.</p>
<p>Or is there a way to avoid the error due to missing directory in <code>sonar.sources</code>? According to <a href="https://github.com/SonarSource/sonar-maven/blob/master/src/main/java/org/sonarsource/scanner/maven/bootstrap/MavenProjectConverter.java#L433" rel="noreferrer">current sonar-maven source</a> missing directories are only ignored if the POM has <code>pom</code> packaging but not for <code>ear</code> or <code>jar</code> modules without resources.</p>
<p>Or should I ensure <code>src/main</code> exists before sonar start? What hook may I use for that?</p>

37,546,086 | Cannot find var in python | <p>At the beginning of my program, I am defining a simple object which sets the configuration for how I am going to call a service. Like so : </p>
<pre><code>document_conversion = DocumentConversionV1(
username='xxx',
password='xxx',
version='2016-05-31')
</code></pre>
<p>I then want to call a service on all files in a directory. I try to do it like so, but I believe the config object cannot be found - it seems to be out of scope, I get this error: </p>
<pre><code>NameError: name 'config' is not defined
</code></pre>
<p>Here is what I have directly after the object creation : </p>
<pre><code>yourpath = 'C:\\Users\\Desktop\\working_folder\\'
for root, dirs, files in os.walk(yourpath, topdown=False):
for name in files:
print(os.path.join(root, name))
config['conversion_target'] = DocumentConversionV1.ANSWER_UNITS
with open(join(dirname(__file__), os.path.join(root, name)), 'r') as document:
print(json.dumps(document_conversion.convert_document(document=document, config=config), indent=2))
</code></pre>
<p>I've tried defining the config object within the for loop/within the with clause, but it still seems to not work. Curiously, if I remove the for loop from the above, it does seem to work (if ran on one file, rather than a folder).</p>
<p>Any ideas what could be the problem here ?</p>

37,548,734 | tsc throws `TS2307: Cannot find module` for a local file | <p>I've got a simple example project using TypeScript: <a href="https://github.com/unindented/ts-webpack-example" rel="noreferrer">https://github.com/unindented/ts-webpack-example</a></p>
<p>Running <code>tsc -p .</code> (with <code>tsc</code> version 1.8.10) throws the following:</p>
<pre><code>app/index.ts(1,21): error TS2307: Cannot find module 'components/counter'.

</code></pre>
<p>It complains about all imports of local files, like the following:</p>
<pre><code>import Counter from 'components/counter';
</code></pre>
<p>If I change it to a relative path it works, but I don't want to, as it makes my life more difficult when moving files around:</p>
<pre><code>import Counter from '../components/counter';
</code></pre>
<p>The <code>vscode</code> codebase does not use relative paths, but everything works fine for them, so I must be missing something in my project: <a href="https://github.com/Microsoft/vscode/blob/0e81224179fbb8f6fda18ca7362d8500a263cfef/src/vs/languages/typescript/common/typescript.ts#L7-L14" rel="noreferrer">https://github.com/Microsoft/vscode/blob/0e81224179fbb8f6fda18ca7362d8500a263cfef/src/vs/languages/typescript/common/typescript.ts#L7-L14</a></p>
<p>You can check out my GitHub repo, but in case it helps here's the <code>tsconfig.json</code> file I'm using:</p>
<pre><code>{
"compilerOptions": {
"target": "es5",
"module": "commonjs",
"noImplicitAny": false,
"removeComments": false,
"preserveConstEnums": true,
"sourceMap": true,
"outDir": "dist"
},
"exclude": [
"dist",
"node_modules"
]
}
</code></pre>
<p>Funny thing is, building the project through <code>webpack</code> using <code>ts-loader</code> works fine, so I'm guessing it's just a configuration issue...</p>

37,551,900 | Index and length must refer to a location within the string when I try to add an extra digit? | <p>Hello so I have a program that generates a Key when you fill in some info in some text boxes. When ever I generate a key that adds an extra 1 or 0 it tells me Index and length must refer to a location within the string, this is the code: </p>
<pre><code>public virtual string GenerateKey(string BreedPub)
{
return GenerateKey() + BreedPub.Substring(0, 3);
}
</code></pre>
<p>and I think it's conflicting with this:</p>
<pre><code>public override string GenerateKey(string BreedPub)
{
string key = null;
if (Pedigree == "1")
{
key = GenerateKey() + BreedPub.Substring(0, 3) + "1";
}
else
{
key = GenerateKey() + BreedPub.Substring(0, 3) + "0";
}
return key;
</code></pre>
<p>now i've tried to change the substring to (0,4) or doing this:</p>
<pre><code>public virtual string GenerateKey(string BreedPub)
{
if (Pedigree == "1")
{
return GenerateKey() + BreedPub.Substring(0, 3) + "1";
}
else if (Pedigree == "0")
{
return GenerateKey() + BreedPub.Substring(0, 3) + "0";
}
else
{
return GenerateKey() + BreedPub.Substring(0, 3);
}
}

<p>but it still gives me the same error message, what could I be doing wrong?</p>

while(True):
# Capture frame-by-frame

<p><em>Avoid providing static methods that alter static state. In common server scenarios, static state is shared across requests, which means multiple threads can execute that code at the same time. This opens up the possibility of threading bugs. <strong>Consider using a design pattern that encapsulates data into instances that are not shared across requests.</strong> Furthermore, if static data are synchronized, calls between static methods that alter state can result in deadlocks or redundant synchronization, adversely affecting performance.</em></p>
<p>I understand all the rest except for the one sentence that is in bold.</p>
<p>How would you do this without essentially changing the field from a static one to an instance one? Isn't that saying, "In a server scenario, avoid using static class-level members as much as you can?"</p>
<p>If it isn't, could you please provide an implementation of the design pattern it is alluding to?</p>

37,558,899 | Efficiently Finding Closest Word In TensorFlow Embedding | <p>Recently, I've been trying to find the closest word to an embedding. The two most notable ways of doing this is by cosine distance or euclidean distance.</p>
<p>I'm trying to find how to efficiently compute the cosine distance for a tensor of shape <code>[batch_size x embedding_size]</code></p>
<p>One approach is to unpack the tensor and the compute the cosine distance</p>
<pre><code> #embedding is shape [vocab_size x embedding size]
array_list = tf.unpack(batch_array)
word_class_list = tf.unpack(embedding)
index_list_of_closest_word = []
for eacharray in array_list:

for eachwordclass in word_class_list:
list_of_distances.append(cosine_distance(eacharray, eachwordclass))
index_list_of_closest_word.append(tf.argmax(tf.pack(list_of_distances)))

<p>However, this approach is terribly inefficient. Is there perhaps a more efficient manner to do this? I know word2vec does this pretty fast and tensorflow, with the power of a gpu, should be able to do these batch calculations in parallel. </p>

37,561,067 | Java Application JMenuBar for all Jforms | I am new to Java. I have programming experience on other programming languages , especially in PowerBuilder
I am writing a Java application with many forms and reports
I want to have a menu common for all jforms and reports ( any window on my application ).
I thought I could create a basic mainframe with the menu on it and the open any other window inside this main frame. I can't figure this out , only with InternalFrames but this is not what I want.
I made my JmenuBar , I put it on JPanel and then I put Jpanel on a maximized JFrame i called "mainframe". Any window from JmenuBar opens in front of "mainframe" Jframe. When I click on "mainframe" any open window goes back of cource , focus is on the "mainframe".
I wrote a mouselistener for Jpanel which brings any open window toFront except "mainframe" of cource. That seems to make the job but I have to write the same listener for the JMenuBar and this has the disavantage of windows "flashing" any time they are coming toFront.
My truly question is :
What is the way you work with JmenuBars?
Do I have to put JmenuBar to any JForm I create?
How can I have a mainframe ( maybe maximized) with the JMenuBar on it always on back and any other window opens inFront of this frame?
What I realy need is a main frame with menu for my application and everything happens inside this frame.
Thanks a lot

37,586,511 | History stuck cleared when clicking on recent apps button | I'm working on a launcher app that basically launches other installed apps on the device with an explicit intent and I have a edge case scenario:
An Activity (Act) creates an intent of an application (App) and starts it by calling startActivity(intent).
App get launched, my Activity going to "stop" state.
After a while I want to get back to my application so I click on "back" hard button that closes App and bring my Application to foreground (resume state).
This is the wanted behaviour.
Here is the edge case:
If I click on the "recent applications" hard button (square icon) while on App is launched, history stuck is lost, and when I return to App, and click on "back" hard button - App exists to the Launcher screen and onResume of my application is being called.
I searched the web for a solution for couple of hours now, maybe I'll find a solution here.

array_push($pieData1, array( "Available seat(s) of " + $pos_chart[$i], $slot_chart[$i]));
}
</code></pre>
<p>This is the code that I use for array that it use to create the chart. The chart is generated, the header of the chart should be "Available seat(s) of xxx position" but it turns out as "0". </p>
<p>So, what I should change?</p>

37,588,751 | SQL: Need to select items by different conditions | <p><strong>My table looks like this -</strong>
<a href="https://i.stack.imgur.com/yhpqJ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/yhpqJ.png" alt="enter image description here"></a></p>
<p><strong>Explanation</strong><br>
I'm working on an online shop that sells <strong>tours</strong> and <strong>spa</strong>. I'm showing all together on one page.</p>
<p></p>
<p><strong>What I need to select?</strong><br>
1. All spa products (based on "Spa" column), no conditions.<br>
2. All parent tours that have children with an upcoming date.</p>
<p></p>
<p><strong>Meaning</strong><br>
Products ID 1, 4, 5.</p>
<p></p>
<p><strong>Why?</strong><br>
Product 6 have a child, but from 1999. And although product 1 have one child at 2000, it has another one in 2017. All spa products are selected by default, without conditions.</p>
<p><br><i>I hope I made my question clear as I could. I would appreciate any help, my SQL is really bad.</i></p>

37,589,127 | What is the best way to create a simple slideshow into an Android project? | <p>I am absolutly new in <strong>Android</strong> development and I am developing my first app.</p>
<p>I have to create something like a <strong>slideshow</strong> that show an image, when the user moove to the right (with the finger on the screen, what's the correct name in Android jargon?) show the next immage, when it moove to the left the previous one is shown.</p>
<p>I have found this example, I have to implement something like the result shown in the attached video: <a href="http://androidopentutorials.com/android-image-slideshow-using-viewpager/" rel="nofollow">http://androidopentutorials.com/android-image-slideshow-using-viewpager/</a></p>
<p>But my doutbs are:</p>
<p>In the prvious tutorial it use 2 external library that have to be added to the project:</p>
<ul>
<li><strong>Universal Image Loader for Android:</strong> for asynchronous image loading.</li>
<li><strong>ViewPagerIndicator:</strong> library to bring circle indicator with ViewPager.</li>
</ul>
<p>Is it a good solution? Or can I obtain the same behavior without using external library but only stuff provided by the <strong>Android SDK</strong>?</p>
<p>I think that the result of the previous tutorial is what I need for my project but I prefer don't use external library and adhere as much as possible to the standard of Android development.</p>
<p>Can you give me some suggestion about the right way to implement this feature?</p>

Here,circle is added to .svg file.And then text to that circle is added. I want to add text at centre of circle and also if number is bigger like 10000 ,it should fit to that circle.
I tried with
.attr('height', 'auto')
.attr('text-anchor', 'middle')
But,as position of text is decided on which node is added(present in .svg file) and not on circle position,it is not working.
Thank you.
