Warning: This site is primarily for myself, to lookup things I’ve already done in the past but could be interesting for you as well.

This page is an attempt to bring several things to paper, which are otherwise only in my head. There’s much I’ve done already in over 17 years of experience in computer & programming.

Programming

I’ll document some adventures encountered while programming several things.

Python

• Comparison of unicode strings doesn’t work

Computer

This is a section with mostly system related topics (ex. list open files in cmd.exe, SSH port tunneling, etc.). I’ve divided it in several categories beginning with Unix based operating systems such as Linux or macOS. For macOS specific topics I’ve put them in a separate category.

• Ubuntu: Apple Keyboard generates strange space character
• Use Linux behind a proxy

• Find empty directories
• Record traffic with tcpdump

MacOS

• Use CrossOver in a shell script
• Mac won’t go to sleep
