39,681,284 | Normalizr - How to generate slug/id related to parent entity | <p>How can I assign id/slug related to the entity's parent using <a href="https://github.com/paularmstrong/normalizr" rel="noreferrer">normalizr</a>?</p>
<p>Example:</p>
<p>API Response for a user call:</p>
<pre><code>{
id: '12345',
firstName: 'John',
images: [
{
url: 'https://www.domain.com/image0',
name: 'image0'
},
{
url: 'https://www.domain.com/image1',
name: 'image1'
}
]
}
</code></pre>
<p>I could define my schemas in the following way:</p>
<pre><code>const image = new Schema('images');
const user = new Schema('users');
user.define({
images: arrayOf(image)
})
</code></pre>
<p>The problem is that images don't have an <code>id</code> property, so normalizr will not be able to distinguish them unless we provide an <code>id</code> property. Of course, we could do something like </p>
<pre><code>const image = new Schema('images', { idAttribute: uuid.v4() });
</code></pre>
<p>and generate unique identifiers.</p>
<p>Suppose we receive a user update and an image's name has been updated. Because we generate unique identifiers in every normalization, we are not able to identify and update the existing image.</p>
<p>I need a way to reference the parent entity (user) in the image entity (either in its id/slug like <code>12345-image0</code>, <code>12345-image1</code> or as a separate property.</p>
<p>What would be the optimal way to achieve this?</p>

39,684,161 | Why an application starts with FPU Control Word different than Default8087CW? | <p>Could you please help me to understand what is going on with FPU Control Word in my Delphi application, on Win32 platform.</p>
<p>When we create a new VCL application, the control word is set up to 1372h. This is the first thing I don't understand, why it is 1372h instead of 1332h which is the <code>Default8087CW</code> defined in <code>System</code> unit.</p>
<p>The difference between these two:</p>
<pre><code>1001101110010 //1372h
1001100110010 //1332h
</code></pre>
<p>is the 6th bit which according to documentation is reserved or not used.</p>
<p>The second question regards <code>CreateOleObject</code>.</p>
<pre><code>function CreateOleObject(const ClassName: string): IDispatch;
var
ClassID: TCLSID;
begin
try
ClassID := ProgIDToClassID(ClassName);
{$IFDEF CPUX86}
try
Set8087CW( Default8087CW or $08);
{$ENDIF CPUX86}
OleCheck(CoCreateInstance(ClassID, nil, CLSCTX_INPROC_SERVER or
CLSCTX_LOCAL_SERVER, IDispatch, Result));
{$IFDEF CPUX86}
finally
Reset8087CW;
end;
{$ENDIF CPUX86}
except
on E: EOleSysError do
raise EOleSysError.Create(Format('%s, ProgID: "%s"',[E.Message, ClassName]),E.ErrorCode,0) { Do not localize }
end;
end;
</code></pre>
<p>The above function is changing control word to <code>137Ah</code>, so it is turning on the 3rd bit (Overflow Mask). I don't understand why it is calling <code>Reset8087CW</code> after, instead of restoring the state of the word which was before entering into the function? </p>

39,685,740 | Calculate sklearn.roc_auc_score for multi-class | <p>I would like to calculate AUC, precision, accuracy for my classifier.
I am doing supervised learning:</p>
<p>Here is my working code.
This code is working fine for binary class, but not for multi class.
Please assume that you have a dataframe with binary classes:</p>
<pre><code>sample_features_dataframe = self._get_sample_features_dataframe()
labeled_sample_features_dataframe = retrieve_labeled_sample_dataframe(sample_features_dataframe)
labeled_sample_features_dataframe, binary_class_series, multi_class_series = self._prepare_dataframe_for_learning(labeled_sample_features_dataframe)
k = 10
k_folds = StratifiedKFold(binary_class_series, k)
for train_indexes, test_indexes in k_folds:
train_set_dataframe = labeled_sample_features_dataframe.loc[train_indexes.tolist()]
test_set_dataframe = labeled_sample_features_dataframe.loc[test_indexes.tolist()]
train_class = binary_class_series[train_indexes]
test_class = binary_class_series[test_indexes]
selected_classifier = RandomForestClassifier(n_estimators=100)
selected_classifier.fit(train_set_dataframe, train_class)
predictions = selected_classifier.predict(test_set_dataframe)

accuracy += accuracy_score(test_class, predictions)
recall += recall_score(test_class, predictions)
precision += precision_score(test_class, predictions)

<p>In the end I divided the results in K of course for getting average AUC, precision, etc.
This code is working fine.
However, I cannot calculate the same for multi class: </p>
<pre><code> train_class = multi_class_series[train_indexes]
test_class = multi_class_series[test_indexes]
selected_classifier = RandomForestClassifier(n_estimators=100)
selected_classifier.fit(train_set_dataframe, train_class)
predictions = selected_classifier.predict(test_set_dataframe)
predictions_proba = selected_classifier.predict_proba(test_set_dataframe)
</code></pre>
<p>I found that for multi class I have to add the parameter "weighted" for average.</p>
<pre><code> roc += roc_auc_score(test_class, predictions_proba[:,1], average="weighted")
</code></pre>
<p>I got an error: raise ValueError("{0} format is not supported".format(y_type))</p>

39,691,186 | How to make a mobile designed site appear similar on differn't screen resoloutions | <p>I am currently designing a mobile site, that would work perfectly on a 320x480 screen. The issue comes, as newer phones don't use that size anymore, and are much much bigger. (As I found out after I put all that effort in and read it on my phone.) I was wondering if there is any easy way to make it all expand the the proper size I would like it to look without going ahead and giving everything a view-width/vw or view-height/vh rating. (Nvm, I wonder how that would impact the font size.)</p>
<p>Or would I need to go ahead and do that, or something similar? (As it would be particularly bad if it wasn't mobile friendly, for a variety of reasons involving it's creation.)</p>

39,696,038 | Why using Bash readonly variable to capture output fails to capture return code $? | <p>Here's example that tries to execute command and checks if it was executed successfully, while capturing it's output for further processing:</p>
<pre><code>#!/bin/bash
readonly OUTPUT=$(foo)
readonly RES=$?
if [[ ${RES} != 0 ]]
then
echo "failed to execute foo"
exit 1
else
echo "foo success: '${OUTPUT}'"
fi
</code></pre>
<p>It reports that it was a success, even there is no such <code>foo</code> executable. But, if I remove <code>readonly</code> from <code>OUTPUT</code> variable, it preserves erroneous exit code and failure is detected.</p>
<p>I try to use readonly as for "defensive programming" technique as recommended somewhere... but looks like it bites itself in this case.</p>
<p>Is there some clean solution to preserve <code>readonly</code> while still capturing exit code of command/subshell? It would be disappointing that one has to remember this kind of exceptional use case, or revert to not using <code>readonly</code> ever...</p>

39,702,135 | Pin one cell in a horizontal UICollectionView to the right | <p>I am implementing a control that behaves like an <code>NSTokenField</code> (the address picker in Mail, for example) for use in iOS. I use a horizontal <code>UICollectionView</code> and my rightmost cell is a <code>UITextField</code>. This control will appear in a form with other textfields that have right-aligned text. For my new control to look right in this context, I'd like for the <code>UITextField</code> to always be at the right edge of the <code>UICollectionView</code> and for selected tags to appear to the left of it.</p>
<p>At the moment, when I first click into this row, the textfield scrolls to the left and then it gets pushed to the right as more tags are added. Once it is flush with the right edge of the <code>UICollectionView</code> (when 'Appetizer' is added in the image below), then I start getting the behavior I want.</p>

Or alternately, some way to pin the fixed-with field to the right. I haven't found a way to implement these ideas, though! </p>
<p>How can I make it so the textfield is always at the right of the <code>UICollectionView</code>?</p>

}
@Module
public final class NetModule {
@Provides
@Singleton
public OkHttpClient provideOkHttp() {
return new OkHttpClient.Builder().build();

<pre><code>@Singleton
@Component(modules = AppModule.class)
public interface AppComponent {
@AppContext Context appContext();
}
@Singleton
@Component(dependencies = AppComponent.class, modules = NetModule.class)
public interface NetComponent {

<p><code>Error:(12, 1) error: This @Singleton component cannot depend on scoped components:
@Singleton com.myapp.service.dagger.AppComponent</code></p>
<p>I understand why depending on <em>different</em> scopes would be bad and disallowed. But why is Singleton depends-on Singleton not allowed? This feels like it should work, since all I'm doing is declaring sibling components. What am I missing?</p>

39,716,796 | Spring Boot Executable Jar with Classpath | <p>I am building a software system to interact with an enterprise software system, using Spring Boot. My system depends on some jars and *.ini files from that enterprise system, so I cannot pack all dependencies in Maven. I would like to be able to run Spring Boot as Executable Jar with embedded Tomcat. I would also like to be able to set the classpath via the command line. So something like:</p>
<pre><code>java -classpath /home/sleeper/thirdparty/lib -jar MyApp.jar
</code></pre>
<p>However, -classpath and -jar cannot co-exist. I have tried "-Dloader.path". It was able to load all the jar files under the folder, but not other things, like *.ini files in the folder.</p>
<p>So is there a way we can make -classpath to work with an Spring executable jar with embedded Tomcat?</p>
<p>Thank you in advance for all the help.</p>
