Durability is the guarantee that data can be accessed after a failure. It seems like this should be very simple: either your system provides durable data storage, or it does not. However, durability is not a binary yes/no property, and instead should be defined as the kinds of failures you want your data to survive…
One under-appreciated characteristic of early microprocessors is the difficulty of distributing power inside the integrated circuit. While...
It's late 2020 and you just got a brand-new Mac with Apple's own ARM processors. Exciting! But what will development be like?
Buckle up kids, as this is a tale. As you may know, I have a lovely podcast at ...
I've previously covered writing my own virtual CPU , but I never really fleshed it out and it was never a real thing... For a while, wel...
This blog post examines a 1980s chip used in a Soyuz space clock. The microscope photo below shows the tiny silicon die inside the package, ...
The Launch Vehicle Digital Computer (LVDC) had a key role in the Apollo Moon mission, guiding and controlling the Saturn V rocket. Like most...
What do you do when you’re stuck at home with a 16-year-old son during a pandemic lockdown? Well, the first answer is that you build a gaming PC. That was a good project with a lot of incentives to complete, but that also meant it was soon over. So, what next? I spotted a post about an outreach project from CERN to…
Since the Raspberry Pi 4 came out last year, we now have an excellent candidate to base the mini server on. The faster processor and option for up to 8GB of RAM opens up more possibilities for what you can do with it, including now being more than capable as a general Linux desktop system, so with all that in mind…
You can upgrade the storage in your Raspberry Pi 4 with an NVMe drive using USB3 to get more reliable storage and faster I/O than an SD…
The Problem Video playback looks better with a higher scan rate. A lot of content that was designed for TV (EG almost all historical documentaries) is going to be 25Hz interlaced (UK and Australia)…
Latest on the 3d-printed keyboard switch project: I've reached a switch design that I think is probably reliable enough, and I've put 3 of them together to form a macro keypad just to see how it all goes together before I commit to a full keyboard. I don't have a number for how many presses the switch lasts, other…
Intel introduced the 8087 chip in 1980 to improve floating-point performance on the 8086 and 8088 processors, and it was used with the ori...
Dmitry.GR: Complete device takeover by blinking at it!
The Intel 8086 microprocessor is one of the most influential chips ever created; it led to the x86 architecture that dominates desktop and...
A few months ago, after my System76 Galago Pro had its second experience with a dead/swelling batery, I decided that it was time to replace it. On February 15th, I ordered a Dell Latitude 7390.
Hard to believe that I’ve had the same PC case since 2011, and my last serious upgrade was in 2015. I guess that’s yet another sign that the PC is over, because PC upgrades have gotten really boring. It took 5 years for me to muster up the
Introduction ARM CPUs have long dominated the mobile world, nearly all Apple and Android phones and tablets utilize some model of ARM processor. However Intel and AMD still dominate the laptop, des…
I wanted to share my journey from start to finish to restore a 1983 IBM Model F XT mechanical keyboard to it's former glory. It includes...
One of the three basic circuit elements just got a lot smaller for the very first time, in what promises to be a trillion-dollar…
This story, like another in the past , started as an eBay purchase that I would soon regret. I was scrolling through my favorite eBay supplier when I found a listing titled Job Lot Of Roughly 350 Various Network Cards . This of course piqued my interest. Some close photo inspection identified a whole load of cards in…
Last year, I was lucky enough to be gifted a Gameboy Color in great shape. Apart from its intended gameplay features, I also wanted to try and build something meaningful with it, so I made this application to control my air-conditioner over its existing, reverse-engineered infrared protocol.
Some people may think some of my past posts get into the weeds, exploring the technical depths of Windows Autopilot, Intune, Windows 10, ConfigMgr, etc. But I would say those generally only g…
My macOS Big Sur Patcher allowed countless users of older Macs to enjoy the new design and features of macOS Big Sur.
While the last few updates about Precursor have focused on evidence-based trust and security, this update is more about the process of making Precursor itself. There is an essential link between evidence-based trust and understanding the manufacturing process: to convince yourself that something has been constructed…
