November 27th, 2014
Comments Off on Test drive Linux

If you have a USB flash drive lying around, you can test drive Linux by creating a live USB. It’s a USB flash drive that contains an operating system that can start from the flash drive.

Comments Off on Raspberry Pi B+

The Model B+ is the higher-spec variant of the Raspberry Pi. It replaced the original Model B in July 2014. Compared to the Model B it has:

  • More GPIO. The GPIO header has grown to 40 pins, while retaining the same pinout for the first 26 pins as the Model B.
  • More USB. We now have 4 USB 2.0 ports, compared to 2 on the Model B, and better hotplug and overcurrent behaviour.
  • Micro SD. The old friction-fit SD card socket has been replaced with a much nicer push-push micro SD version.

Linux on a 68000-based protoboard computer

November 24th, 2014
Comments Off on Linux on a 68000-based protoboard computer

What does it take to build a little 68000-based protoboard computer, and get it running Linux? In my case, about three weeks of spare time, plenty of coffee, and a strong dose of stubborness. After banging my head against the wall with problems ranging from the inductance of pushbutton switches to memory leaks in the C standard library, it finally works! I’ve built several other DIY computer systems before, but never took their software beyond simple assembly language programs. Having a full-fledged multitasking OS running on this ugly pile of chips and wires is a thrill, and opens up all kinds of interesting new possibilities. I’ve named this plucky little machine 68 Katy.

KDE4 Productivity Tips and Tricks

Comments Off on KDE4 Productivity Tips and Tricks

Time is money, so I set up my main PC for maximum productivity. Everything I use the most is no more than a click away, and I have a batch of fave useful CLI and keyboard shortcuts and commands. Life is too short to wade through inefficient GUIs. I like all Linux graphical environments, and the one I keep coming back to the most is KDE. I loved it when it was pixely and not very pretty and had tons of customizability, and now it is sleek and gorgeous and has tons of customizability.
