Random stuff I’m rambling about.

  • Writing systemd enabled applications in Go October 12, 2015 Writing a daemon in Go is really easy given the extensive language environment it provides out of the box. Making your daemon work nicely with Systemd is a little more challenging, especially if want to make use of the Systemd services like socket activations to spawn our daemon on demand and using the journal for ...
  • WiPy quicky October 10, 2015 I’ve received my WiPy + expansion board this week and was a bit disappointed that connecting the micro-USB connector did not provide me direct access to the Python REPL of the WiPy. After some tinkering and reading through the support forum, I found out that there is a rather easy way to enable the Python ...
  • USB armory JTAG port April 4, 2015 When reading further on the USB armory and thinking about the cool things I could do with it, it struck me that I couldn’t find any information on the JTAG port. There are a couple of pads on the bottom side that appear big enough for this purpose, but the documentation do not mention anything ...
  • Giving the USB armory a spin… April 4, 2015 Earlier this week I received my USB armory device, a small SBC made by the people from Inverse Path. The device is not much bigger than a regular USB drive, and contains a Freescale i.MX534 SoC (containing a ARM Cortex A8), 512 MB of memory, a SD card holder and nothing more. Oh yeah, there are ...
  • Tracking multiple service in Felix DM4 March 18, 2015 Apache Felix DependencyManager v4 is out with lots of new features and improvements, which are documented quite well and I’ll not repeat all. Instead, I’d like to highlight two new features that are really convenient in lots of situations where you want to track multiple components of the same type. Suppose we have a service named ...
  • Headless X11 March 17, 2015 updated 2015-12-16: added section on how to start x11vnc in Systemd. In many situations it is quite handy to have a working graphical environment for testing out websites, or doing other sorts of things in which a GUI is more suitable than the command line. When running in a headless situation, accessing the GUI on a ...
  • Tiny DNS server using RPi March 11, 2015 I’ve got numerous headless and virtualised machines up and running at my home. Accessing them by IP address is cumbersome (I tend to remember words better than numbers) and editing your /etc/hosts fileĀ on each and every machine is also not very convenient in this case. Sure, there are solutions like mDNS/Bonjour but this also involves ...
  • Moving in… March 11, 2015 Moved my site to a new hosting company, and am now in the middle of rearranging, migrating and deleting stuff. If you miss anything, feel free to contact me…
  • Debian on the WRAP router platform January 8, 2005 Through a friend of mine, I got my hands on very neat embedded PC from PCengines, the WRAP version 1C. This board contains a 266MHz Geode SC1100 processor (compatible and comparable with an i585 processor), 64Mb onboard DRAM, a compact-flash slot, one or two mini-PCI ports and up to three onboard network cards. All this ...
