Caps lock as super

17 August 2015 • Last edited 10 October 2015

I bought a Chromebook last year, and one of the (possibly) more notable things about its simplified keyboard is a complete lack of any caps lock key. Instead the super key is located where caps lock normally is. I quickly found this a far less awkward position for the super key, and realizing that I didn’t use caps lock anyway, I decided to remap caps lock on my other computers to the super key.

To do this, I just used the following ~/.Xmodmap

clear lock
keysym Caps_Lock = Super_L

Been running it like this for a little over 6 months now, and I couldn’t be happier.

Edit: After I’ve begun using IBus, I found it apparently doesn’t play well with Xmodmap. So I switched over to using XKb, which does work well with IBus. My new configuration (in my xorg.conf.d) is now:

Section "InputClass"
	Identifier "keyboard defaults"
	MatchIsKeyboard "on"

	Option "XKbOptions" "caps:super"
EndSection

Dynmap of all of Denmark

7 June 2015 • Last edited 18 August 2015

So I’m hosting a Minecraft server with all of Denmark in 1:1 scale (accessible on denmark.simpvp.net.) I’ve also put dynmap on the server, for a nice overview of the entire country. The settings are set to vlowres, flat map only. I added dynmap to the server on May 20th, starting the render of the whole world at 12:29 local time. The rendering finished on June 4th 06:12, meaning it took 14 days, 17 hours and 43 minutes to render. All in all dynmap currently takes up 81.2GB of space.

The problem now is that I originally just set the zoom level randomly to 4, given that I had no idea how much you would be able to see with any particular zoom level. Now that it’s finished, it’s clear that this is far too zoomed in, I really wanted the entire country to be visible when zoomed completely out. I did a little bit of math, and figured out that zoom level 8 should definitely show the entire country, and 7 possibly show enough. But the problem there is that it’s not possible to have it render higher zoom levels without redoing the entire render, so I’m going to just set it to 8, and then start the entire render all over again. I’ve also managed to disable the surface map and the caves map since it finished, so we’ll see if that makes any difference for the second render.

Update: Second complete render finished in 14 days, 10 hours and 55 minutes. It is accessible on simpvp.net/denmark

Analysing work during an exam

4 June 2015

I use git for all my digital exams, I have a simple script that just commits all changes every 5 minutes. That way I can go back to old revisions or undelete things as needed. This works pretty well as I write everything in LaTeX. This also means that I can see exactly how much I had done at any point in time. I’ve used this to graph the lines of code in my LaTeX document over time, for a 5 hour physics exam I took 2 days ago.

Exam analysis

It seems I worked more or less continuously for the first 60 or so minutes. After that it’s all in steps, where I’ve had a problem, thought about it, and then written the solution down.
