Editing and even viewing (raw) photographs can be a bit taxing on your CPU. If you have an Nvidia GPU, you can supercharge your photo editor by using its OpenCL extensions to offload operations to. Using darktable myself, I had to do a minor bit of research before it worked …

If you're not using webhooks yet to automate things from automatically generating documentation, running tests, updating websites and web applications based on events, please go read up on them.

I very recently moved this weblog to a new host, and in the process finally changed from Apache running mod_wsgi to nginx with uWSGI and supervisor (well, at least for the Python based web apps, as dammIT is a flat site). I'm using isso as commenting system, which runs as …

In my ~/.ssh/config file, I have been using a socket file for every host that I connect to, so TCP sessions can be re-used for faster connecting to a host I already am connected to. I had several iterations of the exact filename for this, as with longer hostnames …

You might be in that same situation as I was until recently: you open up your ssh config file and start scrolling through the long list of nicely aliased private machines, that organically grown list of work - project A and the comment-section-divided work - project B, work - misc, work - are these …

After Chromebook: for fun and profit? @ 2014-10-05 I got myself an Acer C720p for cheap. It's new, just cheap, as that's how Chromebooks go :) It has a new-fangled touchscreen, which I actually tend to use while on Chrome OS. I hadn't thought I would do so (hey, it's a laptop …

If you get an ugly rectangular dropshadow in Ubuntu Gnome 14.10 with the gnome-staging ppa (because Gnome 3.14 is so slick), install the Intel graphics driver from ppa:mgedmin/ppa; this ppa has a patched xserver-xorg-video-intel that fixes this for Utopic users. source

When your laptop is sitting on a table and you're doing some other stuff in the meanwhile, it might quietly be running out of battery. In that case, you likely want to be nudged to find it a power outlet before it has to shut down or hibernate. Wouldn't it …

While I was standardising my dotfiles I wanted to have an easy and quick way to update my projects so repositories weren't out of date when I wanted to use them (for example when being offline on the train), and I didn't want to go through them by hand every …
