Well that headline looks weird. I mean. You click √ on your calculator. Or you type Math.sqrt() or something similar. But what if you’re writing code on ancient low spec systems and there’s just no way you can take the time to actually...
(No, this is not about Musk supporting a racist, homophobic, bigoted authoritarian - others will write endlessly about that today) Tesla is valued as a software company, not a car company. This is an image they’ve pushed endlessly -...
What you’re seeing in this picture is a screenshot from our “family chat”. It’s a locally hosted Matrix server, with Element clients on all the computers, phones and tablets in the family. Fully End2End encrypted of course - why should...
With Facebook’s release of LLaMa, and the subsequent work done with its models by the open community, it’s now possible to run a state of the art “GPT-3 class” LLM on regular consumer hardware. The 13B model, quantized to 4-bit, runs...
Docker is a powerful tool for managing and deploying applications, but it can sometimes be frustrating to work with. In this post, I want to share my experience with a recent issue I had with rootless Docker, and what I did to resolve...
When people talk about the Atari ST range of computers, most mean the common form factor of the times where the computer and keyboard were all one unit. This was true for most of Atari’s machines - but for a few exceptions. The Mega ST,...
Update 2021-07-14: Ben of The Overlanders commented on my Facebook post that there was yet another optimization possible on the depack-routine. I have edited the source listing below. This weekend yet another instance of the very popular...
(Also includes how to seriously mess something up creating even bigger repair needs) When we bought our property we also purchased a lot of the equipment the previous owner had acquired. An integral part of that is the lawnmower tractor...
Above you see two probes that came with my DSLogic Analyzer. You also see two EZ-Hook XKM-S probes bought from Digikey at 30 SEK each. The latter are vastly higher quality - and much easier to work with since you can place them closer...
I bought a DSLogic Basic USB Logic Analyzer a few years back. It has worked perfectly fine for my use cases. Recently I’ve begun using a Ubuntu desktop more than my Macbook laptops in the workshop, and when it came to installing the...
Love the Tesla Model 3. When I got it I thought the clever way to route a charger cable up from the front USB ports was nice, but after a while I got real tired of having to poke the phone onto the plug whenever I got in the car. The...
Even the retro world is moving away from the regular DIP packaging sometimes. The Atari Falcon, and third party ROM boards from Exxos, use the 27C4096 PROM in PLCC packaging to hold TOS (the operating system). The TL866 with its DIP40...
I own a TL866CS IC programmer. Wonderful device - I truly recommend it (and I assume its successor is even better). It’s been known for many years that the company who made them had one hardware revision, and limited the CS revision...
[this post has been updated, see additional edits being made at the bottom] April 2018 I saw a Facebook ad for a pair of headphones that sounded like the perfect match for my needs. I’m a severe insomniac, and a frequent flier. I’ve had...
