Smuggling USB Sticks
"This Is Not A Film" by Iranian director Jafar Panahi, who is under house arrest in his country for alleged “propaganda against the regime,” will be screened under the Free Jafar Panahi Program of the 13th Cinemanila. The film was smuggled from Iran in a Flash-Drive hidden inside a cake to Cannes for screening a few…

The Core Memory Module from my dad’s homebuilt PDP-11/05
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…

A dozen USB chargers in the lab: Apple is very good, but not quite the best
When you buy a USB charger, how do you know if you're getting a safe, high-quality charger for your money? You can't tell from the outside...

Why I'm returning my Microsoft Surface RT
Do not buy a Microsoft Surface RT yet. I’m typing this with gritted teeth. My 24 hours with the half-baked Surface have been a frustrating challenge, a mix of love and hate. I want want want this…

An Alternate Universe (Microsoft Surface)
On the way to the Apple Store today to buy AppleCare+ for my wife’s new iPhone 5, we passed the new Microsoft Store , coincidentally in the middle of their Surface with Windows RT launch. (That is actually the product’s name. “Surface with Windows RT”.)

The Hardware Renaissance
October 2012 One advantage of Y Combinator's early, broad focus is that we see trends before most other people. And one of the most conspicuous trends in the last batch was the large number of hardware startups. Out of 84 companies, 7 were making hardware. On the whole they've done better than the companies that…

Introducing the USB Stick of Death
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…

This Is Why They Call It a Weakly-Ordered CPU
On this blog, I’ve been rambling on about lock-free programming subjects such as acquire and release semantics and weakly-ordered CPUs. I’ve tried to make these …

A Modern Space Cadet
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…

How to build a windmill
Windmills have always fascinated me and for a long time I was dreaming of one day building my own. Where I live there are still machines from the 1600’s that are just as magnificent today as when they were first built. When you see one standing in a field rotating and converting passing air into usable energy they…

Thanks Mr. Jobs, But it Seems I Can Use a Linux Laptop Now
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

2012 MacBook Pro Powers on By Itself on Rough Roads
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.

The KindleBerry Pi
Curious, how’s the refresh rate? Does the e-ink display refresh fast enough to make typing bearable?

The Laser Doodler
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…

Camera Pi – DSLR Camera with Embedded Computer
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…
