linux

 SnackLinux finally has a domain, snacklinux.org! The source is still on Github and all the ISO images have moved as well.

 For the most part, SnackLinux works. I've been having problems with Busybox, so I've made packages for coreutils, binutils, sed, grep and gawk. When compiling anything, I get:

segfault at 0 ip    (null) sp bfdb1cbc error 4 in busybox[8048000+e8000]

or something along the lines of that. I used the newest Buildroot, 2013.11, to create a new toolchain and cross compile uClibc 0.9.33 for SnackLinux. I have yet to recompile Busybox yet, but I'm working on getting gcc natively working on SnackLinux. Once that is completed, I should be able to compile SnackLinux from within SnackLinux.

 I recently bought another IBM Model M (1395660) on eBay the other day, not thinking that it is actually a terminal keyboard. I thought it has a detachable SDL cable like my current Model M (1391401). I was wrong. Turns out it has a non-removable RJ-45 plug instead, thus being a terminal keyboard. Well, aftering some researching, some were able to get it to work by using an ATMega. I was able to find a pinout of the RJ45 plug on the keyboard, and simply just wire it up to a PS/2 cable. Though apparently, the colour of wire for PS/2 is not standardized, which led to testing each pin to see what it does. I cannibalized an old Microsoft keyboard for the cable and was able to hook the wires up straight to each other.

 Four months later and I finally updated SnackLinux. I changed  SnackLinux from a ramdisk to initramfs, updated the Linux 3.10.1 and cleaned up how things build. The full project is available on my Bitbucket and ISOs are available to download here.

 I've spent the last week or two working on SnackLinux, a small Linux distro. I managed to get uClibc in there, as well as tcc, which makes it somewhat useful. The source of it all is there, so you can compile the distro yourself (sans the packages). There are also ISOs which you can download here and fire them up in a virtual machine.

 The processor on the Raspberry Pi isn't all that fast, so why not offload it? I have a HP ML350 that is mostly idling, except when I need to use PostgreSQL, so I thought to set it up as a desktop server for my Pi.

I set up a RDP server since it works well with Linux and also Windows. First thing's first, install xrdp and all other dependencies:

apt-get install build-essential libpam0g-dev libssl-dev x11vnc vncviewer fakeroot checkinstall x11vnc xrdp rdesktop

Then, install your desktop of choice. I chose XFCE since it's pretty lightweight

apt-get install xfce4

I've had problems getting it to start X remotely, so I fixed it with the following. Do this in the user's account (/home/pi for example)

touch .Xauthority

chmod 600 .Xauthority

Because I wanted the full experience, I wanted to hook up my NES controller to my Raspberry Pi and play NES games. I looked around and didn't find anything that fit my needs.

I wrote a script, that's up on Github now, that converts button presses on the NES controller to keyboard presses. So for example, by pressing the A button it registers as pressing the Z key on a keyboard. How to set it up is all right here.

I spliced the wires on the NES controller (thanks to this diagram) and used a breadboard to connect the appropriate wires to ground, +5V, the data, latch, and clock pin. Now I can play Mario in retroarch with a NES controller!

 I won a Raspberry Pi for getting 3rd place in the Open 7400 Logic Competition, of which HubCityLabs donated the Raspberry Pi. My initial project idea for it was to set up a wall mounted weather station. For the time being I thought I'd mess around with it and get somehwhat familiar on what I'm dealing with.

I downloaded the Rasbian image and wrote it to an SD card. It's recommended that the SD card is a minimum of class 4.

Linux, one way or another, really brings out your inner hacker. I've been tinkering quite a bit with DeLicate Linux. It's a lightweight distro made for old computers that uses the 2.4 kernel. Right now, I have DeLicate running on a Pentium 166 with 64MB of RAM. Surprisingly, Fluxbox and Xchat run without any huge problems. Replacing Bash with Dash helped free up some RAM as well. DeLicate uses pacman as the package manager, so building new packages is as easy as creating a PKGBUILD file.

I have also set up a DeLicate package repsitory and a Git repository for the PKGBUILD files.  So if you have an old Pentium laying around, go fire it up and check out DeLicate. There's an active community too.

So, I have this old Pentium 166 box laying around, so I thought I'd stick Linux on it (of course). At first, I used DeLi Linux and it ran quite well. The problem is, the project changed directions, to ConnochaetOS. They took a more modern take on things, using kernel 2.6 and other modern applications. Most of the newer applications don't run quite well on an older box. So, after finding a mirror of a DeLi Linux that I cloned to a local server, I now had a working respository.
