This week, I went to the tinyML Summit in Burlingame, Calif. TinyML, or running small machine learning models on constrained devices, is one of the most exciting technologies I’ve encountered. But it’s also the one most likely to put people to sleep when I talk about it. Using local computing to handle object or even…
Devices based on the i.MX8 or i.MX8M (such as the Librem phone or MNT Reform) have received popular coverage recently. The number of firmware blobs involved in the bringup of these devices is often a point of discussion. At times, people have considered whether some of these blobs could be replaced with libre…
The physical data format on a Commodore 1541 5¼-inch floppy disk as used by the C64 is completely defined in software. The drive’s operating system fits 170 KB on a disk. This article explores different strategies, each with its pros and cons, to fit up to 246 KB.
A new CPU vulnerability, ‘Reptar,’ found by Google researchers, has been patched by Google and Intel. Here’s what you need to know.
The big question about Artificial Intelligence, other than whether it will destroy human civilization, is the effect it will have on employment.
I'm almost ashamed to admit it, but just 1 year ago when I started working on C64 OS, I didn't have the first clue how the C64 Keyboard worked. I knew there was a thing called the keyboard buffer, but I had cloudy thoughts of it being inside the keyboard itself. When I had to actually write the keyboard scanning…
I found this keyboard on eBay recently, although it wasn’t quite the one I was looking for I still think it is interesting. Let me show you why. This is the keyboard, and you would be forgiven for…
Detailed explanation on how RISC-V boot process works and what role SBI has in the RISC-V software stack. Concrete example with OpenSBI.
Using assembly language test loops to understand the differences between M1 Pro and M3 Pro CPU cores casts new light on their differences.
Raspberry Pi just announced their new Camera Module 3, which comes in four variations (standard and wide angle, normal and NoIR for infrared use), and costs $25 for the standard versions, and $35 for wide angle. That's a step up from the older Camera Module 2, which cost $25 and only came in a 'standard' focal length…
Latest Intel processors deliver world’s fastest desktop frequencies, the world’s best desktop experience for enthusiasts and unparalleled overclocking for incredible performance.
Introduction This part will primarily cover the hardware and related human physical and visual issues with the Apple Vision Pro (AVP). In Part 3, I intend to discuss my issues with the applications…
Intel investigated architectural enhancements and modifications for a 64-bit mode-only architecture.
In my video about the Raspberry Pi 5, I mentioned the new external PCIe port makes it possible to boot the standard Pi 5 model B directly off NVMe storage—an option which is much faster and more reliable than standard microSD storage (even with industrial-rated cards!). Enabling NVMe boot is pretty easy, you add a…
Ever dreamt of designing your own open-source laptop? For a while now I´ve been fascinated by this idea. As you can probably imagine, this is a monumental task that will require a lot of time and resources. Working alone on a project of this size makes matters even more difficult.
Why do the 8-bit designs of the 1970s still generate so much interest?
Background Back in April, the hardware news site cnx-software featured a very nice new small Linux board called Breadbee , that was design...
Stunning and adventurous, Roland's 50th Anniversary Concept Piano combines sound, design, and connectivity into an instrument of the future.
My children are hopelessly addicted to their gaming devices. This is a problem, but not one that I can directly solve because the school mandates that they have both an Android smartphone and a Windows laptop. Rather than to meet the problem head on I figured the better way to address it is to replace consumption with…
(Source: Infoworld, 25th May 1992, p56) We need to start at the beginning, because understanding the timeline of the 486 - Intel's 4th gener...
This is a DS 3600 analog telephone made by Tesla Stropkov in about 1982. It's still functional and to my mind it's absolutely beautiful. Bu...
Coral.ai TPUs are AI accelerators used for tasks like machine vision and audio processing. Raspberry Pis are often integrated into small robotics and IoT products—or used to analyze live video feeds with Frigate. Until today, nobody I know of has been able to get a PCI Express Coral TPU working on the Raspberry Pi…
[There is very lively discussion on Reddit, where it’s trending at #1 both on r/ios and r/apple . There are a bunch of worthy suggestions there on how to improve the feature even more, but one thing’s clear: iPhone users would love to see this come to more devices.]
The ARM powered Thinkpad x13s is the first truly premium Windows on ARM laptop. Let's see how that actually stacks up as a software engineer!
Windows XP I have a lot of fond memories of Windows XP and after feeling nostalgic, I was happy to find out that it’s relatively easy to take it for a spin on an ARM64 Mac using QEMU. I decided to install XP and an assortment of classic software one final time, taking screenshots of the whole process. This included…
