A week ago I showed you Doom on the @wolfssl.com wolfDemo board I designed. This weekend I have: * VU meter using the wolf bark bars * Audio (OPL2 music and SFX) * I2C gamepad support * Massively enhanced rendering engine (maxes out the video SPI when music is off)

I bought a faulty Amiga A570 expecting a repair story. Instead, the black screen led me to a strange fault on my Amiga 500 Plus, and something other reproduction boards may have copied too. linuxjedi.co.uk/when-an-amig... #Amiga #RetroComputing

Fun finding of the day... Every Amiga Raemixx 500 motherboard I can find photos of has a hardware assembly fault which breaks Zorro compatibility. And it might be partly my fault. I'll be writing up everything later this week.

Wherever there is a new computer, embedded or not, someone asks if you can run Doom on it. Last year I created the wolfSSL wolfDemo board. Today I managed to get Doom running on it. There is no sound, so the LEDs act like a VU meter for the sound effects. I haven’t wired up a controller yet either.

I've had several people ask me why we use C instead of Rust or other languages at @wolfssl.com. One of my colleagues wrote an explanation: www.wolfssl.com/why-c-remain...

One of my colleagues named a feature in one of our AI scanning tools "Claudex". It sounds like a window cleaning chemical, but the description is: "Run Claude + Codex in parallel, then synthesize with Claude" I love it! 😁

“… they pointed Mythos at @wolfssl.com. Their findings generated 8 CVEs and triggered the release of wolfSSL 5.9.1. We already spend thousands of dollars a month testing with Opus and other models, and none of them found what Mythos did.” Thanks @linuxjedi.co.uk www.wolfssl.com/how-claude-m...

There has been a lot of opinion about Claude Mythos Preview. As we have had exposure to its output at @wolfssl.com, I wrote about our experiences. www.wolfssl.com/how-claude-m...

Designed something to fix the biggest flaw with my car. The cup holders are too big for my wife’s Pepsi Max bottles.

What does Claude Code's --max-budget-usd flag actually do when you hit the cap? The docs don't say, Claude itself didn't know, and I couldn't find it anywhere online. So I tested it and wrote up the findings. linuxjedi.co.uk/when-the-doc...

Even my hardware has bugs today!

My JBC tower of power (I have two more JBC stations too, but they are off to the side).

A lot of recent headlines blame AI for outages, lost data, or even companies collapsing. In most cases the real problem isn’t AI. It’s broken operational processes. Backups, staging, blast radius, monitoring, the boring stuff that actually prevents disasters. linuxjedi.co.uk/ai-didnt-des...

This is what happens when I let my wife name my car. It is the voice control wake word too 😂

I’ve had a busy week… I’ve created something new. Hopefully I can talk about it soon.

I was reminded why I keep a blog today. I was trying to remember how to flash the RAM in bare metal mode on the STM32MP135-DK today, my searches brought up my own blog post about it 😂 linuxjedi.co.uk/bare-metal-h...

I did a bit of developer relations last night after something kinda exploded on Hacker News. After a chat that ended rather pleasantly, this is the result: blog.feld.me/posts/2026/0...

My Debug Probe was dead, OpenOCD wasn’t cooperating, and I needed answers. Turns out the Segger J-Link is an excellent way to debug a Raspberry Pi Pico once you know the trick. linuxjedi.co.uk/ditching-the... #Embedded #RP2040 #RaspberryPi #Debugging

Related to my previous post, anyone know how to make OpenOCD actually work? Couldn't make it work with a genuine Pico debugger either. I had to use Segger's GUI to do this instead.

I was asked to run a benchmark for an algorithm on a Pico today. It turned into a complex debugging session to figure out I forgot to byte align correctly 🤦‍♂️

This Amiga CD32 arrived with no usable video output, but the real culprit turned out to be hiding in the colour clock circuit. Repairs like this are why I love working on retro hardware. linuxjedi.co.uk/when-pal-goe... #Amiga #RetroComputing

Time to admit dumb thing I did... I was using my Bose NC700 headphones on the Eurostar to Brussels for #FOSDEM. I was in a rush to grab all my things and leave the train. I realised on the return journey, when trying to find them, that I left my NC700s in the seat pocket of the first train 😞

This year for #FOSDEM I gave a demonstration of wolfSSL cryptographic benchmarks on the wolfDemo board I designed. Question for next year, should I demo it on an Amiga instead? 🙂

The fun thing about doing #FOSDEM is not many people come to see me due to my current day job. It is either for #Amiga stuff or my open source work in the past 😁 Time to return home…

A nice present from @daniel.haxx.se today 🙂

All packed and ready to travel to FOSDEM tomorrow. Pop into the AW building and say “hi” if you are around this weekend.

Police at my door this morning made me late for a meeting. Long story, I'll let you caption the CCTV grab of my back garden at the time. For the record, those aren't my sheep 😂

It seems that some people paid an average of over £80 for the ebook version of my 15 year old book this quarter 😂

The ChatGPT year in review is kinda cute.

Hackaday covered one of my blog posts! 🙂

Sometimes I'm proud of the small things I've done in the past. This is a glowing lightsaber for my LinuxJedi logo I designed into a PCB 4 years ago. It is brighter at the bottom than top (intentionally) and it worked first time. My theory worked perfectly.

I bought it a few years ago, in a broken state - and it was still stupidly expensive, but not obscenely stupidly expensive! 😂 @linuxjedi.co.uk then fixed it for me, and it's now an amazing machine, complete with ZZ9000, which also allows proper HDMI output - which is so cool.

Picked up a faulty #Amiga 600 motherboard for £41 and turned it into a fully working board. Reset issues, bad caps, dead composite output, all fixed. linuxjedi.co.uk/reviving-an-...

I recently repaired an A1200 with a tricky hidden fault, only for it to return with even stranger ones. Broken HSYNC trace, collapsing ceramics, PS/2 mouse weirdness, audio clipping… this board had everything. linuxjedi.co.uk/the-amiga-12...

Posted mostly because @kari.bsky.social said it would be cool to see it, my current soldering setup. JBC T210, T245, PA120 tweezers, DR560 desoldering gun, JT 6040 hot air / tripod vacuum system. Also, watch Kari's videos if you are into retro stuff and on a soldering journey.

It seems JBC used my nickname on a package. I can't see it on my account anywhere, but it put a smile on my face 🙂

17 years ago I was at MySQL and hacking in useful small UX features in my spare time. Today I’m still doing it for projects I work on. It is now much easier to see how much of an impact different compiler options have on memory usage as well as performance. www.wolfssl.com/benchmarking...

Medical Professional: "We usually only see this condition once or twice a year. Typically caused by stress. Are you going through some stress now?" Me: "Only all the time" MP: "Yea, you look tired" Erm... Thanks? 🙂

“Recap it!” isn’t always the cure. A badly recapped Amiga 1200 came across my bench, and what I found might surprise you. Full story: linuxjedi.co.uk/why-recappin... #Amiga1200 #RetroRepair #Commodore #RetroComputing

I’ve wanted an original copy of the CDTV version of Xenon II since I got my CDTV. It is extremely rare. I now finally have it!

Something I've been working on in the background this year 🙂

An #Amiga 1200 landed on my repair bench that was stuck in a boot loop. DiagROM showed Paula behaving weird. Found the Paula capacitor loose. Can you then see what I spotted was wrong with it afterwards? So obvious that I wasn’t even looking for it 🤦

Over a decade ago, a bunch of us inside OpenStack were teaching people about cloud resilience engineering. Glad to see that today's outages show many didn't listen...

I guess my bag was ejected 😂
