On a Linux system if you upgrade a shared object that is in use any programs that have it mapped will list it as “(deleted)” in the /proc/PID/maps file for the process in question. When you have a system tracking the stable branch of a distribution it’s expected that most times a shared object is […]

My last post was read directly (as opposed to reading through Planet feeds) a lot more than usual due to someone sharing it on lobste.rs. Presumably the people who read it that way benefited from reading it and I got a couple of unusually insightful comments from people who don’t usually comment on my blog. […] For my ETBE-Mon [1] monitoring system I recently added a monitor for the Linux load average. The Unix load average isn’t a very good metric for monitoring system load, but it’s well known and easy to use. I’ve previously written about the Linux load average and how it’s apparently different from other Unix like OSs […] C is Not a Low Level Language [1] is an insightful article about the problems with C and the overall design of most current CPUs. Interesting article about how the Boeing 737Max failure started with a takeover by MBA aparatcheks [2]. Interesting article about the risk of blood clots in space [3]. Widespread human spaceflight […] Currently there’s two things I want to do with my PC at the same time, one is watching streaming services like ABC iView (which won’t run from non-Australian IP addresses) and another is torrenting over a VPN. I had considered doing something ugly with iptables to try and get routing done on a per-UID basis […] 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 […] |
