Answer : Yes, you can. But First argument should be an array. So, you must do it this way $_SESSION['names'] = array(); array_push($_SESSION['names'],$name); Personally I never use array_push as I see no sense in this function. And I just use $_SESSION['names'][] = $name; Try with if (!isset($_SESSION['names'])) { $_SESSION['names'] = array(); } array_push($_SESSION['names'],$name);

Example 1: size array python size = len ( myList ) Example 2: python get array length # To get the length of a Python array , use 'len()' a = arr . array ( ‘d’ , [ 1.1 , 2.1 , 3.1 ] ) len ( a ) # Output : 3 Example 3: find array length python array = [ 1 , 2 , 3 , 4 , 5 ] print ( len ( arr ) )

Answer : try with regular expresion: import re r = re.compile('.*/.*/.*:.*') if r.match('x/x/xxxx xx:xx') is not None: print 'matches' you can tweak the expression to match your needs Use time.strptime to parse from string to time struct. If the string doesn't match the format it raises ValueError . If you use regular expressions with match you must also account for the end being too long. Without testing the length in this code it is possible to slip any non-newline character at the end. Here is code modified from other answers. import re r = re.compile('././.{4} .{2}:.{2}') s = 'x/x/xxxx xx:xx' if len(s) == 14: if r.match(s): print 'matches'

Answer : Sounds like a job for VLOOKUP! You can put your 32 -> 1420 type mappings in a couple of columns somewhere, then use the VLOOKUP function to perform the lookup. Without reference to the original problem (which I suspect is long since solved), I very recently discovered a neat trick that makes the Choose function work exactly like a select case statement without any need to modify data. There's only one catch: only one of your choose conditions can be true at any one time. The syntax is as follows: CHOOSE( (1 * (CONDITION_1)) + (2 * (CONDITION_2)) + ... + (N * (CONDITION_N)), RESULT_1, RESULT_2, ... , RESULT_N ) On the assumption that only one of the conditions 1 to N will be true, everything else is 0, meaning the numeric value will correspond to the appropriate result. If you are not 100% certain that all conditions are mutually exclusive, you might prefer something like: CHOOSE( (1 * TEST1) + (2 * TEST2) + (4 * TEST3) + (8 * TEST4) ... (2^...

Answer : I'm not 100% sure. But IIRC, the problem with normal USB storage is Android has to partition your phone for internal storage and USB storage. Your computer can then umount the USB storage from phone and mount it in your computer. So in many phones without MTP, even though the internal storage had capacity like 16GB, only 1 or 2 GB was available for app installation. While some phone gave up to 8GB for app, that space was wasted for people who didn't need that much for app but needed space for music and photos. With MTP mode, there isn't separate partition but a whole single partition. So if you have 16GB internal storage in your phone, you can use whole 16GB for apps, music and photos. MTP mode is available from Honeycomb and I don't think it's an optional component. I mean I don't think you can say I don't want MTP mode, I want USB storage mode.

Answer : Imagine that we have 3 buttons for example public class MainActivity extends ActionBarActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); // Capture our button from layout Button button = (Button)findViewById(R.id.corky); Button button2 = (Button)findViewById(R.id.corky2); Button button3 = (Button)findViewById(R.id.corky3); // Register the onClick listener with the implementation above button.setOnClickListener(mCorkyListener); button2.setOnClickListener(mCorkyListener); button3.setOnClickListener(mCorkyListener); } // Create an anonymous implementation of OnClickListener private View.OnClickListener mCorkyListener = new View.OnClickListener() { public void onClick(View v) { // do something when the button is clicked // Yes we will handle ...

Answer : You have some options to handle this deprecation the right (and future proof ) way, depending on which kind of drawable you are loading: A) drawables with theme attributes ContextCompat.getDrawable(getActivity(), R.drawable.name); You'll obtain a styled Drawable as your Activity theme instructs. This is probably what you need. B) drawables without theme attributes ResourcesCompat.getDrawable(getResources(), R.drawable.name, null); You'll get your unstyled drawable the old way. Please note: ResourcesCompat.getDrawable() is not deprecated! EXTRA) drawables with theme attributes from another theme ResourcesCompat.getDrawable(getResources(), R.drawable.name, anotherTheme); Edit: see my blog post on the subject for a more complete explanation You should use the following code from the support library instead: ContextCompat.getDrawable(context, R.drawable.***) Using this method is equivalent to calling: if (Build.VERSION.SDK_INT ...

Example: heroku no web processes running spring boot Create Procfile with just web: java -Dspring.profiles.active=default -Dserver.port=$PORT -jar target/*.jar then on the heroku CLI : heroku ps:scale web=1

Answer : I quickly wrote a class with future method to test this behaviour. public class FutureClassLimitsTest { @future(callout=true) public static void docallouts(){ for(Integer i=0;i<200;i++){ Http http=new Http(); HttpRequest hr=new HttpRequest(); hr.setMethod('POST'); hr.setEndpoint('https://google.com'); http.send(hr); } } } This is the error I get. First error: Too many callouts: 101. So I believe this is uniform for the whole platform irrespective of the transaction(Sync or Async). Is there a workaround? Well unless there is a strong business requirement it is kinda bad doing so many callous in a transaction. We can call a Queauble Method from Queueable method,.. and you can chain them infinitely. Thus using proper implementation you can have 100+ callouts. Batch is another way to tackle this. You have to write /modify data model add a some queue cus...

Answer : I have tried this before, using an Avago sensor harvested from an optical mouse. It doesn't work. The resolution is excellent but the accuracy is terrible. And the calibration varies with distance from material to the sensor. I arranged a test with a 3" diameter wheel and the sensor reading the outside "tread" of the wheel. I also put a flag on the wheel, passing through an optical interrupter sensor. The number of counts read per revolution varied by a few tenths of a percent, nowhere near good enough repeatability for machining. I guess you could use the optical mouse sensor in combination with an accurate but low-resolution sensor to fill in the in-between points. But really, I think other sensor technologies are more appropriate for this. Neat idea. I considered using a hacked Livescribe pen with special dot rails for the same purpose, then an absolute location would be provided, rather than the relative location a basic optical mouse wou...

Answer : Okay, the solution is that I did not disable Time Machine and remove all backup drives first. Doing that solved the issue. So the full solution is: Disable "Backup Up Automatically" in Time Machine System Preferences, and remove all backup drives, such that it looks like this: Then run sudo tmutil thinlocalsnapshots / 999999999999 And try again. Optionally restart the computer and try again. In Mojave, what I had to do was turn off Time Machine and then run this command to force clean out the local snapshots: tmutil thinlocalsnapshots / 1000000000 1 where 1000000000 is the size of your drive and the "1" means urgent. This has to be done a few times since it only cleans up a few local snapshots each time. After that, you should be able to see sufficient space available with this command: diskutil apfs resizecontainer disk0s2 limits Open activity monitor and force quit backupd , then click continue in the bootcamp assistant.

Answer : I know this is a late answer, but it might be useful. Here's a proper and clean way to get this done, as @karima's mentioned above. You can actually fire two functions at once; trigger and dismiss the modal. HTML Markup; <!-- Button trigger modal --> <ANY data-toggle="modal" data-target="TARGET">...</ANY> <div class="modal fade" id="SELECTOR" tabindex="-1"> <div class="modal-dialog"> <div class="modal-content"> <div class="modal-body"> ... </div> <div class="modal-footer"> <!-- ↓ --> <!-- ↓ --> <ANY data-toggle="modal" data-target="TARGET-2" data-dismiss="modal">...</ANY> </div> </div> </div> </div> Demo Without seeing specific code, it's difficult to give you a precise answer.
