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 […] I recently changed my KVM servers to use the kernel command-line parameter nomodeset for the virtual machine kernels so that they don’t try to go into graphics mode. I do this because I don’t have X11 or VNC enabled and I want a text console to use with the -curses option of KVM. Without the […] For a long time the Thinkpad has been widely regarded as the “Rolls-Royce of laptops”. Since 2003 one could argue that Rolls-Royce is no longer the Rolls-Royce of cars [1]. The way that IBM sold the Think business unit to Lenovo and the way that Lenovo is producing both Thinkpads and cheaper Ideapads is somewhat […] In late 2013 I bought a Nexus 5 for my wife [1]. It’s a good phone and I generally have no complaints about the way it works. In the middle of 2016 I had to make a warranty claim when the original Nexus 5 stopped working [2]. Google’s warranty support was ok, the call-back was […] I’ve just attended a lecture about improving memory, mostly about mnemonic techniques. I’m not against learning techniques to improve memory and I think it’s good to teach kids a variety of things many of which won’t be needed when they are younger as you never know which kids will need various skills. But I disagree […] |
