I wanted to play Doom 3 on my mac. I know that there's an App Store version but I had just bought the Windows version from steam and I didn't want to pay the extra $10 to buy the game again.
The game engine is open source and some good folks had already made it work on macOS so I just downloaded and compiled. I also fixed some configuration so that you can just unpack a zip file in the windows installation folder and run it with double click.
I tried creating a standalone .app but I failed as the app didn't seem to be able to find bundled libraries unless I set DYLD_LIBRARY_PATH so I did...

I find it useful to be able to open a picture's location with nautilus using a shortcut in darktable. This is only for gnome for the time being but I'm posting here in case somebody else finds it useful.

If you want to engrave things with your reprap you can add a laser diode. I have
come across some guides that explain how to salvage one from an old DVD burner.
There is also the quite expensive JTech Photonics addon which I'm certain would
provide some advantages over this solution, but it was out of budget.
However I saw that these things are available quite cheaply from the usual
places on the net and promise 3x the power of the DVD burner diode.
You will need a heatsink for that and a driver, that looks like this
There are quite some variations so I will not show a pinout, but...

I have a PC at home that works as an entertainment center. I run spotify on it and control it
with my smartphone so I don't even have to turn on the monitor to listen to my tunes.
However, I'm not alone at home and I'd like my SO to be able to do that too, without
having to log in and out of spotify all the time.
I triede creating a separate user account and run it as that with gksudo but I
ran into a number of permission issues. I was able to run it by doing xhost +
but it still was unable to play music.
The next step was to just override $HOME, which worked, but when I tried to...

My digital photography journey started with a 2mpix HP photosmart 315, and went on to a Pentax S4. In 2007 I decided I had to get on the DSLR bandwagon.
Note: I digress quite a bit in this article. As I find background info useful to understand if the writer fits my style and if I should actually give weight to the opinions present, I decided not to shorten it. But if you don't care about why I decided on the D750 and just want to actually read about the D610 and D750, scroll down to The present
The 350D
It all started with the Canon 350D, the kit 18-55 and a Sigma 55-200 which was soon...

I wanted to import my firefox passwords into a keepass2 .kdbx database. This guide was very helpful until the point where neither KeePassX2 Alpha nor MacPass have a way to import from XML (MacPass has the menu entry but as of this time it is not implemented)
From there, I downloaded the regular KeePassX (version 1.x) imported from the XML and saved as a normal .kdb file. MacPass fortunately handles .kdb files, and you can easily drag and drop groups from one MacPass window to another.
Thus the only thing left to do was to open the .kdb with the imported firefox passwords side by side...

Greek has only one (actually two, but the umlaut (διαλυτικά) is rare) accent character and it is used once in all words with more than one syllable. As such it is waaay faster to type the character before the corresponding letter than long pressing the letter to choose from the alternatives, especially since it is so frequently used. Most people leave this task to the auto-correct but as there are words that differ only at the place of the accent, and as I don't use autocomplete I prefer having a dedicated accent character.
Very few android keyboards have this and I couldn't find...

I've been playing around with blender and darktable recently. I was trying to use a highpass filter as a mask for soften in darktable but not have it affect the final image, which (except if I don't understand something correctly) is impossible. Immediately the node editor of blender sprang to mind.
This would allow the result of any filter (especially low and high pass) to be used as a mask (or factor as blender has it) of another filter. Another bonus is that it allows reordering of the filters, and that two completely different pipelines could be mixed right at the end.
Blender has...
Hi there. Mix't is my new weblog. I'm still debating if I should move over some, or all my blog posts from the old place, but from now on, you will find here lots of different subjects about the things I'm doing from time to time. Welcome, and I hope you enjoy the read.
