won't put a final zero in a.
coherent with the unix point of view "everything is file", including
"files" that have no intrinsic length

How do you validate a URL with a regular expression in Python?
...tloc to always be "www.somename.somedomain"? Do you want the path to look unix-like? Or windows-like? Do you want to remove the query string? Or preserve it?

Is SHA-1 secure for password storage?
...he system for not letting an attacker build an offline attack. That's what Unix systems do: the hashed passwords, which used to be in the world-readable /etc/password file, are now in the /etc/shadow file which is protected against read access, except by a few privileged applications.

Why do I need 'b' to encode a string with Base64?
...gt;
There are two problems I planted:
If I tried to send that email in Unix, the email would send as soon as the \x04 character was read, because that is ASCII for END-OF-TRANSMISSION (Ctrl-D), so the remaining data would be left out of the transmission.
Also, while Python is smart enough to esc...
What's “wrong” with C++ wchar_t and wstrings? What are some alternatives to wide characters?
...only on it to decide that you can use wchar_t this way because, while most unix platforms define it, Windows does not even though Windows uses the same wchar_t locale in all locales.
The reason Windows doesn't define __STDC_ISO_10646__ is because Windows use UTF-16 as its wchar_t encoding, and beca...
