I have a column in my dataframe that I want to recode into different values. I just started with Pandas and i'm a bit more confident with functions so I want to use a function that I can map/apply on that column. Most of the script is working as intended. but I can't seem to find the right syntax for the missing value check in this function.

I used MediaMuxer and MediaCodec to generate a mp4 video.

The video is playble after I call mMediaMuxer.stop()

However, when the user quit the app before I get the change to call the stop() method, I am left with a big mp4 file that is not playable.

Is there anyway to repair this mp4 file to make it playable?

Here is one example of a corrupted mp4 file

And I was able to repair the file using this online tool but this tool asked to upload a non-corrupted video as reference.

Here is the non-corrupted mp4 video that I used as reference. When I uploaded this video, the tool repaired my broken mp4 file.

So it is possible to repair the file but how did they do it?

If useful, here is the code I used to generate both corrupted and non corrupted

I'm following a super simple tutorial with minimal config edits. When I try to create a producer in a Java app it cannot find the broker. However when I set up a console producer I can produce and consume via the same broker.

I am a bit new to Qt C++ and I think there is a small thing I'm missing but can't figure what is it.

I am trying to make a simple Qt C++ application just to get familiar with it, but I face some problem, First, I have the votor class, which is the main application class, and another class which is called recorder, which will be used inside the main votor class. For simplicity, I omitted un-related parts, Here are the files:

I'll call the translationRecord as an Ajax when I need it will be called. However, an error occurs before the request because there is no value. That's why I want to know how to make an exception.

I already received the data in ajax and then I used that jquery to add that data to the blade template.
