Ripping a DVD, Linux style

Recently we got a DVD. After turning it around in our hands a few times and giggling at our reflections, we ordered an external USB DVD/CD eater so we actually could ingest some of its contents. As the hip techy people we are, having this material available to us …

projectM on Ubuntu

Lately, I was thinking back to the time when I had my 15" CRT monitor (and later my whopping 19" flat CRT) tuned to the beats that Winamp was playing for me. It was a famous plugin called Milkdrop, and it provided nicely psychedelic looking visuals based on the audio …

Roundcube webmail and Google contacts

Draft digging time! Something I've had in my drafts since the 25th of October, 2014, apparently: Roundcube is a decent self-hosted webmail solution, which benefits from integrating Google Contacts so you do not have to duplicate your address books (assuming you use Google for yours). Luckily someone wrote a plugin …

vim reloaded

An update about what I do with vim, making it more powerful and taking away some of the envy I have for the excellent IDE's out there (for example PyCharm and the rest of the IntelliJ family by JetBrains - try it, it's awesome). Also, it makes vim look a lot …

Ever needed to unzip a bunch of zip files into their own directory and you don't want to do so one by one? No? Well, here I have a oneliner for you anyway: ls -1 *.zip | while read zf; do echo ${zf::-4}; unzip "$zf" -d "${zf::-4}"; done This …

darktable and opencl in Ubuntu 19.04

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 …

webhaak all the things

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. In the meanwhile, I've basically hooked up all my personal projects based on webhooks in GitHub and gitea, powered by my …

isso commenting system in a subdirectory on nginx

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 …


Andromeda, Substratum and a Chromebook

Andromeda is a way to theme an Android device with Substratum without needing root. You need adb though, so a desktop or laptop computer is needed to initiate the connection between the Andromeda app and Substratum. On regular machines this is not much of an issue, but Chromebooks are both …

ssh config.d to tidy up that archeology-worthy ~/.ssh/config

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 …

How to smooth up your Firefox on Linux, including video

After having one of our Hangouts videocalls, I started looking into why the browser plugin takes so much CPU-time (and makes the laptop hot and breezy in the process). Is stumbled upon the article How to tell if you're using hardware acceleration and dove into my own about:support page …

A solution to some odd Gnome 3.16 issues

I'm running Ubuntu Gnome 15.04 with the ppa's to bring me Gnome 3.16 (gnome3-team and gnome3-staging). After a bit of fiddling (removing some old extensions and packages), I got it to show me GDM. After getting into the desktop, there were some odd issues though. These issues also …

Acer C720p Chromebook: my new hacktop

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 …
