I am trying to create a multi-select form control, however, whenever I select something it does not get rendered. The function handleChange does get the event.target.value but it does not seem to add to the roleIds state. Furthermore, the console.log for the variable selected does not log anything to console.

Component Code:

I'm following this tutorial and this Custom Detector Example in order to implement Custom Lint Rules. Basically what I've done is:

1. Create a new Android Project in Android Studio;
2. Create a java module for project created in step 1;
3. On module's build.gradle, import Lint API dependencies;
4. Create an Issue & IssueRegistry & CustomDetector;
5. Reference the IssueRegistry on module's build.gradle;
6. Create Unit tests;

My problem is, during the execution of my JUnits, I always receive "No Warning". When I debug the test, I can see that my Custom Detector isn't called, what am I doing wrong?

I would like to test the trained built-in VGG16 network in MxNet. The experiment is to feed the network with an image from ImageNet. Then, I would like to see whether the result is correct.

However, the results are always error! Hi, how stupid the network is! Well, that cannot be true. I must do something wrong.

I am trying to make a simple screen scraper on this site - List of Javascript libraries it should be run through console and return all the libraries as text without categories. I managed to get all of them with code below. They also mentioned we can use a map() function for mapping the contents however I was unable to do that. My question is how to loop through all the categories and concatenate various arrays into one single array of library names? Any help appreciated!
