Linux: lubuntu

I decided to give lubuntu a try:
lubuntu is a faster, more lightweight and energy saving variant of Ubuntu using LXDE, the Lightweight X11 Desktop Environment.
If you already have Ubuntu installed, trying lubuntu is really easy; just run "sudo apt-get install lubuntu-desktop".

In summary, it's very pretty, super fast, and crazy small. In fact, its memory usage was almost laughable considering I was running it on a 4GB MacBook Pro. I think my total memory usage was something in the 200-300MB range.

The downside is that there are a lot of things that I've grown accustomed to in Ubuntu that I can't live without. Ubuntu has a GUI to swap the capslock key with the control key, and it has a GUI to tweak my touchpad and power management settings. There are probably ways to configure these things by hand under lubuntu, but I've grown mildly impatient in my old age ;)

The biggest challenge for me was that lubuntu doesn't know about encrypted home directories. I have an encrypted home directory, and Ubuntu knows that it has to run ecryptfs-mount-private when I log in; in fact, it doesn't even need to ask me for my password again since it does it as part of the login process. When I ran lubuntu, I had to log in, run ecryptfs-mount-private (typing in my password again), log out, and then log back in.

I have a couple more tips. To access the OpenBox menus, middle click on the desktop. If you decide to install lubuntu, don't tell it to switch to lxdm. Otherwise, if you remove lubuntu, you'll end up with a borked gdm setup. To fix it, you'll need to remove and reinstall gdm.

In summary, I really like lubuntu. It makes my machine feel lightning fast, faster than any other computer I've ever owned--at least until I fire up NetBeans ;) I'm not sure if they'll fix the things I mentioned, but if those things don't affect you, I think lubuntu is worth a try.

I've been wondering about the caps lock issue as well. I'd like it to act as the Super key by default which is easy to do in Ubuntu, but Lubuntu's lxinput GUI doesn't support that.

Actually, appending the following to /etc/xdg/lxsession/Lubuntu/autostart does the trick, at least when using the Finnish keyboard layout:

setxkbmap -option caps:super

Thanks for the tip :)

other possibilities are

setxkbmap -option ctrl:swapcaps # Left Control <-> Caps Lock

setxkbmap -option ctrl:nocaps # Caps Lock -> Control

That's really helpful. Thanks.

Ubuntu 20.04 on a 2015 15" MacBook Pro

I decided to give Ubuntu 20.04 a try on my 2015 15" MacBook Pro. I didn't actually install it; I just live booted from a USB thumb drive which was enough to try out everything I wanted. In summary, it's not perfect, and issues with my camera would prevent me from switching, but given the right hardware, I think it's a really viable option. The first thing I wanted to try was what would happen if I plugged in a non-HiDPI screen given that my laptop has a HiDPI screen. Without sub-pixel scaling, whatever scale rate I picked for one screen would apply to the other. However, once I turned on sub-pixel scaling, I was able to pick different scale rates for the internal and external displays. That looked ok. I tried plugging in and unplugging multiple times, and it didn't crash. I doubt it'd work with my Thunderbolt display at work, but it worked fine for my HDMI displays at home. I even plugged it into my TV, and it stuck to the 100% scaling I picked for the othe

ERNOS: Erlang Networked Operating System

I've been reading Dreaming in Code lately, and I really like it. If you're not a dreamer, you may safely skip the rest of this post ;) In Chapter 10, "Engineers and Artists", Alan Kay, John Backus, and Jaron Lanier really got me thinking. I've also been thinking a lot about Minix 3 , Erlang , and the original Lisp machine . The ideas are beginning to synthesize into something cohesive--more than just the sum of their parts. Now, I'm sure that many of these ideas have already been envisioned within , LLVM , Microsoft's Singularity project, or in some other place that I haven't managed to discover or fully read, but I'm going to blog them anyway. Rather than wax philosophical, let me just dump out some ideas: Start with Minix 3. It's a new microkernel, and it's meant for real use, unlike the original Minix. "This new OS is extremely small, with the part that runs in kernel mode under 4000 lines of executable code.&quo

Haskell or Erlang?

I've coded in both Erlang and Haskell. Erlang is practical, efficient, and useful. It's got a wonderful niche in the distributed world, and it has some real success stories such as CouchDB and Haskell is elegant and beautiful. It's been successful in various programming language competitions. I have some experience in both, but I'm thinking it's time to really commit to learning one of them on a professional level. They both have good books out now, and it's probably time I read one of those books cover to cover. My question is which? Back in 2000, Perl had established a real niche for systems administration, CGI, and text processing. The syntax wasn't exactly beautiful (unless you're into that sort of thing), but it was popular and mature. Python hadn't really become popular, nor did it really have a strong niche (at least as far as I could see). I went with Python because of its elegance, but since then, I've coded both p
