A couple of years ago a relative who uses a Linux workstation I support bought a 4K (4096*2160 resolution) monitor. That meant that I had to get 4K working, which was 2 years of pain for me and probably not enough benefit for them to justify it. Recently I had the opportunity to buy some […]

One problem I’ve had recently on two systems with NVideo video cards is KMail crashing (SEGV) while reading mail. Sometimes it goes for months without having problems, and then it gets into a state where reading a few messages (or sometimes reading one particular message) causes a crash. The crash happens somewhere in the Mesa […] It seems to me that Android phones have recently passed the stage where hardware advances are well ahead of software bloat. This is the point that desktop PCs passed about 15 years ago and laptops passed about 8 years ago. For just over 15 years I’ve been avoiding buying desktop PCs, the hardware that organisations […] A very famous blog post is Straight White Male: The Lowest Difficulty Setting There Is by John Scalzi [1]. In that post he clearly describes that life isn’t great for straight white men, but that there are many more opportunities for them. Causes of Death When this post is mentioned there are often objections, one […] One thing I should have learned before (but didn’t) and hope I’ve learned now is to photograph sysadmin work. If you work as a sysadmin you probably have a good phone, if you are going to run ssh from a phone or use a phone to read docs while in a server room with connectivity […] As a follow-up to my post with Suggestions for Trump Supporters [1] I notice that many people seem to have private definitions of words that they like to use. There are some situations where the use of a word is contentious and different groups of people have different meanings. One example that is known to […] In February I reviewed a Thinkpad X1 Carbon Gen 1 [1] that I bought on Ebay. I have just been supplied the 6th Generation of the Thinkpad X1 Carbon for work, which would have cost about $1500 more than I want to pay for my own gear. ;) The first thing to note is that […] I’ve recently setup fail2ban [1] on a bunch of my servers. It’s purpose is to ban IP addresses associated with password guessing – or whatever other criteria for badness you configure. It supports Linux, OpenBSD [2] and probably most Unix type OSs too. I run Debian so I’ve been using the Debian packages of fail2ban. […] Like most people I use Certbot AKA Letsencrypt to create SSL certificates for my sites. It’s a great service, very easy to use and it generally works well. Recently the server running www.coker.com.au among other domains couldn’t get a certbot certificate renewed, here’s the error message: Failed authorization procedure. mail.gw90.de (http-01): urn:acme:error:unauthorized :: The client […] I’ve had some discussions with Trump supporters recently. Here are some suggestions for anyone who wants to have an actual debate about political issues. Note that this may seem harsh to Trump supporters. But it seems harsh to me when Trump supporters use a social event to try and push their beliefs without knowing any […] |
