| | 39 | * Warning with ''async, threads, and parallel tasks'': If you have things that runs in paralel, nothing ensures you that A would happen before B even if in the code its declared on this way. For example: You have a code that generates a temporal html file with statistics, then you open it with a browser in background to visualize it, then you copy it to a backup directory and finally since this is a temporal file you simply delete it, on this example you could experience that the browser fails, why this could happen? I used the example of a browser because is a bloated ton of crap and so it takes some time to open, in the meantime the script has continued and removed the file, when the browser is ready to print it the file is gone. |
