Some of the best examples I’ve seen of anarchy working have been in corporate environments. This doesn’t mean that they were perfect or even as good as a theoretical system in which a competent manager controlled everything, but they often worked reasonably well. In a well functioning team members will encourage others to do their […] Since forking the Mon project to etbemon [1] I’ve been spending a lot of time working on the monitor scripts. Actually monitoring something is usually quite easy, deciding what to monitor tends to be the hard part. The process monitoring script ps.monitor is the one I’m about to redesign. Here are some of my ideas […] MBox is the original and ancient format for storing mail on Unix systems, it consists of a single file per user under /var/spool/mail that has messages concatenated. Obviously performance is very poor when deleting messages from a large mail store as the entire file has to be rewritten. Maildir was invented for Qmail by Dan […] Last year I wrote about how great my latest Thinkpad is [1] in response to a discussion about whether a Thinkpad is still the “Rolls Royce” of laptops. It was a few months after writing that post that I realised that I omitted an important point. After I had that laptop for about a year […] I’m currently doing some embedded work on ARM systems. Having a virtual ARM environment is of course helpful. For the i586 class embedded systems that I run it’s very easy to setup a virtual environment, I just have a chroot run from systemd-nspawn with the --personality=x86 option. I run it on my laptop for my […] I previously wrote about running my SE Linux Play Machine over Tor [1] which involved configuring ssh to use Tor. Since then I have installed a Tor hidden service for ssh on many systems I run for clients. The reason is that it is fairly common for them to allow a server to get a […] I decided to try packaging Mesos for Debian/Stretch. I had a spare system with a i7-930 CPU, 48G of RAM, and SSDs to use for building. The i7-930 isn’t really fast by today’s standards, but 48G of RAM and SSD storage mean that overall it’s a decent build system – faster than most systems I […] I have forked the “Mon” network/server monitoring system. Here is a link to the new project page [1]. There hasn’t been an upstream release since 2010 and I think we need more frequent releases than that. I plan to merge as many useful monitoring scripts as possible and support them well. All Perl scripts will […] Last year I blogged about blacklisting a video driver so that KVM virtual machines didn’t go into graphics mode [1]. Now I’ve been working on some other things to make virtual machines run better. I use the same initramfs for the physical hardware as for the virtual machines. So I need to remove modules that […] Debian/Stretch has been frozen. Before the freeze I got almost all the bugs in policy fixed, both bugs reported in the Debian BTS and bugs that I know about. This is going to be one of the best Debian releases for SE Linux ever. Systemd with SE Linux is working nicely. The support isn’t as […] |
