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. I recently installed mailnag to regularly check my IMAP mail account and notify me when new mail arrives.  Mailnag is really […]

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. I use cron to schedule the execution of a number of programs that perform a variety of tasks (e.g. backups).  By default, Ubuntu 18.04 is configured to log […]

Hmm. We’re having trouble finding that site.

Having problems connecting to sites with browsers like Firefox and Chrome?  Do pages seem to hang with a “Performing TLS Handshake” message at the bottom?  Is it particularly bad if you try to open multiple tabs all at once?  Here’s one reason why that happens, and how to fix it. I do most of my […]

Suppressing messages in /var/log/syslog

Running Ubuntu or some other Linux distro?  Seeing lots of pointless messages in /var/log/syslog?  Want to be able to stop/suppress/filter the entries from a particular program so that they don’t obscure the more important ones?  I’ll show you how. Lots of Linux users peek inside of the logs that accumulate in /var/log/ every-so-often to keep […]

The ‘best’ way to brace a wooden door or gate

Got a sagging wooden door or gate?  Building a new one?  Not sure how you should brace it?  Confused about the conflicting advice you may have read elsewhere?  Read on. 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 […]

Passively-cooled CPU Thermals

The Completely Silent Computer I built relies entirely on passive cooling.  Some folks are keen to know how well (or poorly) it works in the real world.  Can it adequately cool a loaded system, or does thermal throttling make it pointless?  Well, it’s time to find out. As can be seen in these images, the […]
