3D-printed legs for a nightstand
08 Nov 2019Looks like I’m printing a lot of legs for different things, just to make life of our home robotic cleaner easier. Now it’s for a nightstand, which was of exactly wrong height for our robot.

25 Oct 2019Our robotic vacuum was constanstly being stuck by trying to go over a clothes drying rack. So I’ve decided to raise it a bit about the floor, and 3D-printed some legs for it.
Read more…Fully reproducible NixOS builds
28 Sep 2018One of big strengths of NixOS is reproducible builds. Yet achieving
full reproducibility requires a bit of effort. The minimal set of
things needed is a configuration.nix and a reference to a
nixpkgs commit. And the easiest way to achieve this is to have a
git-repo with configuration, which also references nixpkgs as a
submodule.
Sharing code position from emacs
23 Jul 2018 There are times when you want to share an exact code location with somebody. Maybe you’ve just shown them something and want to follow up with an IM message. Or you want to add something to a bug tracker issue. The thing is that a code is opened in your favorite editor, so you know everything about a commit, a file and a line number. But to share a link you need to go to some kind of a web git UI and search for exact same things there. Read more…Salomon X Ultra MID 2 GTX aren't good
18 Mar 2018Looks like there are no normal boot manufacturers left on the planet. I welcome Salomon to my shit-list with their X Ultra Mid GTX (not sure about the exact model). Here what they look like after everyday use for just 8 months:

17 Mar 2018When you are developing a threepenny app, you need to perform the
same dance after every change: recompile and restart the app, and
then manually reload a page in a browser. This becomes tiresome
very quickly. But with the help of ghcid and with small changes
to your Haskell code you can completely automate this process.
Notes about installing Lineage OS on Nexus 6P
15 Mar 2018Checklist for myself for the next time I’ll be flashing my Nexus 6P (because official Lineage OS instructions are missing some important parts).
Read more…Perl `JSON::XS` can produce un-canonical JSON
14 Mar 2018Sometimes you want to produce a canonical version of a data
structure in JSON - with keys sorted and no additional
whitespace. JSON::XS promises us that we can achieve such result
with a canonical option. It only notes that canonicalization
doesn’t work for tied hashes. But I’ve just spent half a day
debugging to learn that this is a bit more complicated.

19 Apr 2017As RabbitMQ is gradually adopting Elixir (i.e. for the next generation of its CLI tools), it’s natural that one would also want to use Elixir for writing plugins. There is a blog post from 2013 on that topic and most things there are still relevant - except the build instructions, as there was a complete revamp of build system in RabbitMQ. And I’m going to fill that gap.
