Writing Your Own Sudo
What does sudo do? One might think that sudo is actually some binary deeply integrated into the kernel, relying on a special purpose-built system call to achieve its functionality. After all, it lets you use root without even providing the password for that account! But thanks to one bit inside file permissions, sudo can exist without any of this. Let's write our own version of sudo to prove this point.

Modern Python projects need a bit more than venv and pip - Learn about the best tools for package management and environment isolation.

Python support for regular expressions
Regular expressions are a common feature of computer languages, especially higher-level languages like Ruby, Perl, Python, and others, for doing fairly sophisticated text-pattern matching. Some languages, including Perl, incorporate regular expressions into the language itself, while others have classes or libraries that come with the language installation. Python's standard library has the re module, which provides facilities for working with regular expressions; as a recent discussion on the python-ideas mailing shows, though, that module has somewhat fallen by the wayside in recent times.
