Iterator Loop vs index loop [duplicate]
I'm reviewing my knowledge on C++ and I've stumbled upon iterators. One thing I want to know is what makes them so special and I want to know why this:

...e should ever write readlines()[1] in example code. In this case you may know the file only has two lines, but someone else blithely assuming it's a good solution might try it on a million-line file and get a rather nasty surprise.

Process escape sequences in a string in Python
...Adding a regular expression to solve the problem
(Surprisingly, we do not now have two problems.)
What we need to do is only apply the unicode_escape decoder to things that we are certain to be ASCII text. In particular, we can make sure only to apply it to valid Python escape sequences, which are...
live output from subprocess command
...ou must call proc.stdin.close() to close the pipe, so that the subprocess knows there is no more data coming through.)
Suppose you want to capture stdout but leave stdin and stderr alone. Again, it's easy: just call proc.stdout.read() (or equivalent) until there is no more output. Since proc.stdo...

Why should casting be avoided? [closed]
...e cast does nothing more than tell the compiler (in essence): "shut up, I know what I'm doing" -- i.e., it ensures that even when you do a conversion that could cause problems, the compiler won't warn you about those potential problems. Just for example, char a=(char)123456;. The exact result of thi...
Why is volatile not considered useful in multithreaded C or C++ programming?
...mpiler. If the compiler understands the semantics of a memory barrier, it knows to avoid tricks like that (as well as reordering reads/writes across the barrier). And luckily, the compiler does understand the semantics of a memory barrier, so in the end, it all works out. :)

If your site performs sensitive operations, you really need someone who knows what they’re doing, because this can’t be covered in a single answer. You need to use HTTPS, HSTS, CSP, mitigate SQL injection, script injection (XSS), CSRF, and a gazillion of other things that may be specific to yo...
