So, back in 1997 I installed my first copy of FreeBSD. I had to do some major research to get X Windows up and running, and the next computer I bought I very carefully selected a video card to make things easier. I was happy, I was able to use gcc, but getting online via
I have a stack of half finished projects that I'm trying to complete. Happily, the first one was finished late last night: a long range Wi...
Several months back we have been playing with different file systems on various system platforms, examining the security posture and robustness of numerous device drivers’ implementations. One of the configurations we spent some time on was the commonly used NTFS on Microsoft Windows – as the file system is rather…
Last April I sent a weather balloon up into the stratosphere after months of preparation. You can read all the details starting here . I c...
Curious, how’s the refresh rate? Does the e-ink display refresh fast enough to make typing bearable?
Or, A Heterogeneous Supercomputer in Every Pocket In the twilight of Moore’s Law, the transitions to multicore processors, GPU computing, and HaaS cloud computing are not separate trends, bu…
As a child I'd made a crystal radio set and had been meaning to make one again when I came across stories of foxhole or PoW radios made f...
When I woke up, my RSS reader showed some "occupy thingiverse" things posted on Thingiverse. I'm still trying to figure out all that happen...
While driving around in the wilds on the bumpy roads of the White Mountains , my MacBook Pro with Retina display keeps waking up. When I pull it out of the leather bag I keep it in, I find that the battery is partly drained, and it is hot.
First, let me go on the record as saying I'm a huge Raspberry Pi fan. If you ...

A while back I wrote an analysis of fake microSD cards. As a result of the post, I’ve received this question regularly via email:
So, you're a decent paranoid person, running only open source software on your box: Linux, GNU, etc. You have the feeling you could, if you ...
I’ve had the idea of embedding a computer DSLR camera for a couple of years now, but for whatever reason I never got around to implementing it, mostly due to the cost of small single board computers. Until now, that is. With the release of the Raspberry Pi, embedded computing has all of a sudden become much more…
So I’ve got a project coming up (that may have something to do with this tweet ) that will require a few LED matrix displays. I found a suitable candidate online and ordered one to play around with. Since I already had the display, I thought it’d be fun to run it through the paces and build a little circuit out of it…
 Ideas for your Raspberry Pi!The chances are you have a Raspberry Pi or there's one on the way to you, n
This is basically the 1974 version of a DIMM. It measures 16″ by 11.5″ and holds 16 kilobytes. It’s technically 18 bits wide but only 16 were used in the PDP-11. The raised part in the middle is where the cores are actually stored. Each bit is a little ring with 3 wires running through the middle. By running current…
I spend a lot of my time (easily over 8 hours a day) at a keyboard. As you might have guessed from my previous entries about Vim and Mutt I'm not averse to spending a few hours to improve an environment I'm going to be spending tens of thousands of hours in over the next few years, so it shouldn't be a shock that my…
