AI Didn’t Destroy Your Company, Your Processes Did Some things happening in this industry are making me feel old lately. Problems we hit and solved decades ago are being hit again today. People are discovering the same solutions, just giving them new…

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.

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

I’ve taken to plan & implement tests and then plan & implement implementation. Especially for bug fixes. Otherwise it doesn’t always do it in the right order.

I’ve had a busy week…

I’ve created something new. Hopefully I can talk about it soon.

Bare Metal “Hello World” on an STM32MP135F-DK Whilst I do like working with STM32 development boards, some basic information I need can often be buried in pieces of documentation, videos and examples. Today I wanted to simply echo “Hello World”…

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 😂

I *think* I saw them in my local Tesco when I was last there. But it is getting harder to buy physical gaming magazines in shops.

The thieves take pity when they find it wasn’t an iPhone.

Yea, that one caused a lot of upset. WH Smith kept the profitable train station and airport ones. Sold off the rest, which got a rebrand.
A bit like why you only see Dixons in airports now.

Unless you are going to the train station, it is TGJones now. WH Smiths sold off their regular retail

WolfSSL Doesn't Suck You're Just Holding It Wrong My previous post made some rounds on the internet. However, there has been a happy ending to this saga. I've revisited my test environment as their requirement of building...

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...

Seeing them as a "cloud titan" reminds me of this meme.

In the tech world, the news often moves faster than you can type 🙂

I joined the MariaDB Foundation - lefred blog: tribulations of a MariaDB Community Advocate Last Friday was my last day at Oracle. Today is my first day at MariaDB.org! Of course, this move is a big surprise for many people, but not for me, and it might not be for those following the MySQL e...

@datadictum.bsky.social might need to edit this, Frederic Descamps announced today that he works for MariaDB Foundation 🙂

Ditching the Debug Probe: Using a Segger J-Link with a Raspberry Pi Pico I was working on benchmarking some new code on a Raspberry Pi Pico today and needed to debug it. This proved to be more difficult than it should be, so I figured I would document how I did it.

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.

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 🤦‍♂️

When PAL Goes Wrong: Repairing an Amiga CD32 What should have been a straightforward CD32 recap turned into something far more interesting. The CD32 belongs to Tony Warriner, known for Broken Sword and Beneath a Steel Sky, and more recently UrbX...

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.

#Amiga #RetroComputing

Not looking good, not handed in at the train’s destination.

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 😞

It is a development board designed around an STM32U585 MCU. The current firmware runs the wolfCrypt benchmark and spits out the results over UART.

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…

#curl stickers at the wolfSSL booth at #FOSDEM

Yep, it is a real PCB 🙂

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

LOL! I guess the fact that so many people get ill there that there is usually a “FOSDEM flu” probably doesn’t make it sound better 😂

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

That’s cool, but for full DOS compatibility for sound blaster, it is hard without ISA

CCTV image of me in my back garden with two police officers and two sheep.

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 😂
