QUESTION
I built an app using Django 3.2.3., but when I try to settup my javascript code for the HTML, it doesn't work. I have read this post Django Static Files Development and follow the instructions, but it doesn't resolve my issue.
Also I couldn't find TEMPLATE_CONTEXT_PROCESSORS, according to this post no TEMPLATE_CONTEXT_PROCESSORS in django, from 1.7 Django and later, TEMPLATE_CONTEXT_PROCESSORS is the same as TEMPLATE to config django.core.context_processors.static but when I paste that code, turns in error saying django.core.context_processors.static doesn't exist.
I don't have idea why my javascript' script isn't working.
The configurations are the followings

Answered 2021-Jun-15 at 18:56Run ‘python manage.py collectstatic’ and try again.
The way you handle static wrong, remove the static dirs in your INSTALLED_APPS out of STATIC_DIRS and set a STATIC_ROOT then collectstatic again.
Add the following as django documentation to your urls.py
QUESTION
I wrote a demo with some inline assembly (showing how to shift an array of memory right one bit) and it compiles and functions fine in GCC. However, the with Clang, I'm not sure if it's generating bad code or what but it's unhappy that I'm using memory despite the "rm" constraint.
I've tried many compilers and versions via Godbolt and while it works on all x86/x86_64 versions of GCC, it fails with all versions of Clang. I'm unsure if the problem is my code or if I found a compiler bug.

The problem is your code. In GNU assembler, parentheses are used to dereference like unary * is in C, and you can only dereference a register, not memory. As such, writing 12(%0) in the assembly when %0 might be memory is wrong. It only happens to work in GCC because GCC chooses to use a register for "rm" there, while Clang chooses to use memory. You should use "r" (bytes) instead.
Also, you need to tell the compiler that your assembly is going to modify the array, either with a memory clobber or by adding *(unsigned char (*)[16])bytes as an output. Right now, it's allowed to optimize your printf to just hardcode what the values were at the beginning of the program.

I'm currently using Winsock2 to be able to test a connection to multiple local telnet servers, but if the server connection fails, the default Winsock client takes forever to timeout.
I've seen from other posts that select() can set a timeout for the connection part, and that setsockopt() with timeval can timeout the receiving portion of the code, but I have no idea how to implement either. Pieces of code that I've copy/pasted from other answers always seem to fail for me.
How would I use both of these functions in the default client code? Or, if it isn't possible to use those functions in the default client code, can someone give me some pointers on how to use those functions correctly?

select()can set a timeout for the connection part.
Yes, but only if you put the socket into non-blocking mode before calling connect(), so that connect() exits immediately and then the code can use select() to wait for the socket to report when the connect operation has finished. But the code shown is not doing that.
setsockopt()withtimevalcan timeout the receiving portion of the code
Yes, though select() can also be used to timeout a read operation, as well. Simply call select() first, and then call recv() only if select() reports that the socket is readable (has pending data to read).
Try something like this:

I am trying to use beginMoveColumns to move a single column over in a QTableView, but it doesn't work properly in my example below. The cell selections get shuffled and column widths don't move. Moving rows using the same logic seems to work correctly. What am I doing wrong?
ANSWER
Answered 2021-Jun-15 at 20:13Turns out it was a bug, I made a bug report here: https://bugreports.qt.io/browse/QTBUG-94503
As a workaround I just clear cell selection on column move, and use this snippet to move column widths

I'm trying to parallelize a merge-sort algorithm. What I'm doing is dividing the input array for each thread, then merging the threads results. The way I'm trying to merge the results is something like this:

Answered 2021-Jun-15 at 01:58I'm trying to parallelize a merge-sort algorithm. What I'm doing is dividing the input array for each thread, then merging the threads results.
Ok, but yours is an unnecessarily difficult approach. At each step of the merge process, you want half of your threads to wait for the other half to finish, and the most natural way for one thread to wait for another to finish is to use pthread_join(). If you wanted all of your threads to continue with more work after synchronizing then that would be different, but in this case, those that are not responsible for any more merges have nothing at all left to do.
This is what I've tried:
QUESTION
I've started to create UI tests for my PyQt5 widgets using QtTest but have run into the following difficulties:
In order to speed up things, some of my widgets only perform operations when visible. As it seems that QtTest runs with invisible widgets, the corresponding tests fail.
For the same reason, I cannot test program logic that makes a subwidget visible under certain conditions.
Is there a way to make widgets visible during test? Is this good practice (e.g. w.r.t. CI test on GitHub) and is QtTest the way to go?
I have tried to use pytest with pytest-qt without success as I couldn't find a proper introduction or tutorial and I do know "Test PyQt GUIs with QTest and unittest".

Answered 2021-Jun-15 at 17:01The problem is simple: QWidgets are hidden by default so isVisible() will return false, the solution is to invoke the show() method in init() to make it visible:

How to get the return value? Attach my code. My intention: Want to check the QListWidget and if it's empty, a message Box popup will raise and ask the option from the user. Problem: At the stage of beginning itself, a Message box popup will display, (I don't want it at the beginning stage), If the QListwidget is empty then the MessageBox popup will display as desired, and if we select "Yes" or " No" Button, Nothing will return/print in the first file.

Answered 2021-Jun-15 at 16:49In first it is not necessary to make the verification be done in a new class, it is also logical that you invoke func_create_newitem since as you point out that method must be invoked when the item was not found.

QUESTION
I am writing a program in C language using gtk3 library. I want it to be able to receive a h264 video stream from a certain IP address (localhost) and UDP/RTP PORT (5000).
In order to do it, I am using gstreamer to both stream and receive the video.
I managed to stream the video using the following pipeline :
send.sh :
gst-launch-1.0 filesrc location=sample-mp4-file.mp4 ! decodebin ! x264enc ! 'video/x-h264, stream-format=(string)byte-stream' ! h264parse ! rtph264p
I managed to display the video in a new window using the following pipeline :
receive.sh :
gst-launch-1.0 udpsrc port=5000 caps="application/x-rtp,encoding-name=H264" ! rtph264depay ! decodebin ! videoconvert ! autovideosink
At this point, everything works fine. But now I want to receive the stream and display it inside my C/GTK program. I am using the following code (found on internet and adapted to make it compile) :
