When should I use Inline vs. External Javascript?

Since this execution is basically free (as the server side is talking to the database) it must be clear that all of these jumps would cost more than doing no jumps at all. If there were a browser quirk that said external js executes faster we could measure wh...

I am moving the free-function to create these to the end now:
A free-function (iterator version) would look like something this and you could even have defaults:

(Note: Use exec python -c ... to replace the current shell, this frees one PID. The solution can be improved with some IO redirection as well, freeing unused FDs. This is up to you.)
How this works (I think): ctypes.CDLL(None) loads the standard C library and runs the pause() function i...

My personal summary of SCTP is that it doesn't do anything you couldn't do another way (in TCP or UDP) with substantial application support. The thing it provides is the ability to not have to implement that code (bad...
Why does this C++ snippet compile (non-void function does not return a value) [duplicate]
...ndard does not require this to generate an error.
So compiler vendors are free to generate a warning if they are quite sure that a function is missing a return and the user is then free to ignore/mask that warning in those rare cases where the compiler was actually wrong.

How to add a new audio (not mixing) into a video using ffmpeg?
...ows you to manually select streams / tracks. See FFmpeg Wiki: Map for more info.

Difference between malloc and calloc?
...use malloc so it can (potentially) give you dirty memory from its internal free list instead of getting new pages from the OS. (Or instead of zeroing a block of memory on the free list for a small allocation).
Embedded implementations of calloc may leave it up to calloc itself to zero memory if ...
