In this installment: some strange things I discovered when purchasing a FreeDOS laptop from Hewlett Packard. I suspect that the audience for this will be somewhat limited but I had fun exploring this. Perhaps you, dear reader, will find a chuckle in here too.
I'm increasingly of the view that both my time and my sanity are worth more and more as the years progress. Particularly in my independent life, it really can be that black and white - if I can't work, it costs me money. Plus, I want to be happy
There are many good, modern solutions for reading data off old floppy discs and drives. Perhaps the best is the Greaseweazle : it's capable,...
Alan Kay recently gave his 1970's Xerox Alto to Y Combinator and I'm helping with the restoration of this legendary system. The Alto was t...

[ An updated treatment of some of this material appears in Chapter 6 of the Energy and Human Ambitions on a Finite Planet (free) textbook. ]
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”.)
A few months ago I stumbled on a tweet pointing out a kind of SFP optic that claimed to be smart, made by a Russian company Plumspace . After going through their Smart SFP product listings I was on-board and decided I needed to have some of them.
There’s a great joke in Futurama, the cartoon comedy show, about a horror movie for robots. In the movie, a planet of robots is terrorized by a giant “non-metallic being” (a mons…
So Oxide is making some cool stuff huh? Big metal boxes with lots of computer in them. Servers as they should be! Too bad I can’t afford to buy one for myself… but wait, they’re open-sourcing the software they’re writing to do it. Mom said we can have Oxide at Home!

Today I want to show you a watch modification that I've been working on. I'm calling it the Data Runner, and it's another F91W mod, this time going the extra mile to make something functional and nice looking.
A lot of people have asked about the computers I used to train TorToiSe. I’ve been meaning to snap some pictures, but it’s never “convenient” to turn these servers off so I keep procrastinating. We had some severe thunderstorms today here i
I want to talk about the Nokia N9 (2011) alarm clock application because it’s a really nice example of thoughtful, functional design – and because it’s only on the N9, so a lot of people won’t have seen it.
Modified curve tracer is applying AC voltage. Horizontal axis represents voltage and the vertical axis represents current. In both cases, the curve always passes through zero voltage and current. This requirement must be met in order to be classified as a memristor.
This is one of these things that look very obvious to me, to the point where it seems not worth discussing. However, I've heard the idea that "hardware magically makes things cheap" from several PhDs over the years. So apparently, if you aren't into hardware, it's not obvious at all.
Note: I also posted a separate review of some A2 'Application Performance' class cards, see this post: A2-class microSD cards offer no better performance for the Raspberry Pi. As a part-time tinkerer and full-time developer, I have been fascinated by single board computers (SBCs) since the first Raspberry Pi was…
The Goal – Explain What is Magic Leap Doing Magic Leap has a way of talking about what they hope to do someday and not necessarily what they can do anytime soon. Their patent applications ar…
Today Raspberry Pi Trading announced the Raspberry Pi 400, the latest in the series of small education-focused computers that started with the original Raspberry Pi in 2012. For years, people have come up with creative ways to hack a Pi into keyboards, like the Original Pi in an old Mitsumi keyboard, or the Pi 3 A+ in…
The last 100 seconds of 8088 MPH sound very different to the rest of the demo. The end tune is actually a 4-channel Amiga MOD file (which you can download here ) composed by coda . Playing back a MOD through PC speaker on such a slow machine has never been done before. Here is how we did it.
AMD is sending us the two MI300X boxes we asked for. They are in the mail.

ARM64EC (and ARM64X) Explained Probably the most confused looks I get from other developers when I discuss Windows and ARM64 is when I used the term " ARM64EC ". They ask is the same thing as ARM64? Is it a different instruction set than ARM64? How can you tell if an application is or ARM64 ARM64EC?
