Below function is returning None despite having return statement. This seems to be a simple problem but i am unable to figure out the solution being a python beginner. The findurls function works perfectly but the second function -"murls" seems to have a problem.

I am trying to develop a means of scheduling a Runnable after a least amount of time has elapsed. The code should start with a request being made and count down until an amount of time has elapsed, and then execute the Runnable. But I also need that there can be more than one requests made, and for each new request the delay will be renewed before the Runnable is executed.

The goal is to achieve the following behaviour: When the user scrolls a JList, an adjustment listener in the vertical scroll-bar of the JList's JScrollPane will request the delay before the Runnable is executed. Each time the user scrolls a new request is made, so the delay is renewed. The request returns immediately so that the EDT is blocked for the least amount of time. So the waiting and executing of the Runnable should occur in a different Thread (than the EDT). After a least amount of time has elapsed, from the last made request, the Runnable is executed.

I need this behaviour because the JList will contain many thousands of thumbnails of images. I don't want to pre-load all the thumbnails in the JList because they might not fit into memory. I don't want to load thumbnails as the user scrolls either, because he can make arbitrary fast scrolls let me put it. So I only want to start loading thumbnails after the user waits/settles in a single location in the JList for an amount of time (say for example 500 ms, 1 second, or something between).

What I have tried is to create an entirely handmade scheduler with worker Threads. Follows my effort, with relative explanations in the comments:

I take photos and record videos with my phone camera and keep all of them on my internal storage/sdcard. I periodically back them up on my PC, so I keep these camera photos on PC storage in sync with phone storage.

For years, I've been backing up my phone camera photos to my PC in the following way:

1. Plug in phone into PC and allow access to phone data
2. Browse phone storage → DCIM → Camera
3. Wait several minutes for the system to load a list of ALL photos
4. Copy only several latest photos which haven't been backed up yet

I figured that waiting several minutes for all photos to load is an unnecessary drag so I downloaded adb platform tools. I've added the folder bin to my Path environment variable (i.e. %USERPROFILE%\Tools\adb-platform-tools_r28.0.3) so that I can seamlessly use adb and not write its full path each time.

I wrote the following script for Git Bash for Windows. It is also compatible with Unix if you change the $userprofile variable. Essentially, the script pulls camera photos between two dates from phone storage to PC.

I have a Arraylist of items and I stored them inside my viewmodel and when I click on an item from the listview it has to store the details of the items and show them in the master detail page.

This is my viewmodel:

I need to write an application to open the browser (sample site www.onet.pl), which will restart every 3 hours. The commotion of restart was displayed. I managed to create such a layout, but I can not handle the cyclical restart. Please help where to add and what code? One class is enough.

This is my code:

My C++ teacher once told me that if I have to use a break to get out of a loop I didn't think enough about the loop condition.

So did she (very good teacher btw) just fail to mention that foreach loops are an exception to this rule (which I have generally found to be true) or is there indeed a way to get out of a foreach loop without using a break?

I am asking in general, but most interesting for me would be for Java or PHP.

Edit: In case I haven't made this clear, I am wondering if there is a way to get out of a foreach-loop without using a break. Not sure what this whole commotion is about, what's wrong with that question?

I have a fairly vanilla Vagrant setup running trusty64. It's being configured by a single shell file. Among others, it contains an aliasing of python3 to python and pip3 to pip, respectively:
