Tips & tricks

Here is my “black book” with all the tricks I might forget. Some of them are odd, others may be useful.

Unlike articles, my tips are often not detailed at all, and I do not provide step by step instructions.

• Linode information script
• Build i386 Debian packages within an amd64 system
• Change the Subject: header of messages not going through antispam filter
• Clear dpkg status file
• Move SPAM to Junk folder and mark as read
• Numlock on startup
• Optimize MySQL tables
• Purge all packages
• Use secure-apt with unofficial repositories
