Recovering from a freeze in Linux

Ever had your Linux system freeze on you?  The mouse either doesn’t move, doesn’t register clicks, or both?  The keyboard seems completely unresponsive?  Can’t think of any way to regain control of your system except to press the power button?  Worried you might corrupt the filesystem if you do?  Fear not.

Tweaking Python programs

If you’re not a Python programmer but you’re trying to customise some Python code anyway, and your changes do not seem to make a difference, then there might be a simple explanation and fix.

Logging CRON messages to a different file

Noticed that a lot of the messages in /var/log/syslog are from CRON and anacron?  Would you prefer that they be directed to a different file?  Easy Peasy.

Lots of Linux users peek inside of the logs that accumulate in /var/log/ every-so-often to keep […]

Wooden doors and gates come in many different shapes, sizes and styles.  A very simple one would look something like this: Unfortunately, if you build […]

Passively-cooled CPU Thermals (Part 2)

In the first Passively-cooled CPU Thermals post I looked at how the completely fanless Streacom DB4 I built performed under various CPU loads.  A question over on Silent PC Review asked how the thermal curve looked when the CPU was unloaded.  Good question — let’s find out! It seems logical that a passively-cooled computer that […]
