...econd set of credentials that would give them access - bad user experience all around.
Consider most operating systems - when you attempt to read a file you don't have permission to access, you aren't shown a login screen!
Thankfully, the HTTP specifications were updated (June 2014) to remove the...

...the text from OpenQA concerning this issue (found here):
HTML automatically normalizes
whitespace within elements, ignoring
leading/trailing spaces and converting

...GitHub’s official solution to this problem.
raw.githubusercontent makes all files use the text/plain MIME type, even if the file is a CSS or JavaScript file. So going to https://raw.githubusercontent.com/‹user›/‹repo›/‹branch›/‹filepath› will not be the correct MIME type but inste...

Peak-finding algorithm for Python/SciPy
...ant to understand well its parameters width, threshold, distance and above all prominence to get a good peak extraction.
According to my tests and the documentation, the concept of prominence is "the useful concept" to keep the good peaks, and discard the noisy peaks.

Passing references to pointers in C++
As far as I can tell, there's no reason I shouldn't be allowed to pass a reference to a pointer in C++. However, my attempts to do so are failing, and I have no idea why.

What exactly is nullptr?
