How do you remember that the brown wire is live? It is the color of your pants if you touch it.

probe-rs, rtt, and defmt will seriously spoil you. Semihosting is awfully slow in comparison. Rust will spoil you.

Sometimes I wish I wouldn't hear coil whine. Though, a $300 TB4 Dock from @razergermany.bsky.social really shouldn't have audible (and very annoying) coil whine.

Have the folks who are telling everyone that you can vibe code anything in a few hours these days actually tried vibe coding anything beyond a hello world? AI is still dumb as a nail.

Yeah, no, it was an absolute brilliant idea to write the Windows start menu in React and NodeJS. I totally wanted to have my start menu not accessible. /s

"A C program is like a fast dance on a newly waxed dance floor by people carrying razors." — Waldi Ravens (Seen on the C documentation of the Avro C library)

Actually, humanity deserves to go extinct. I'm slowly losing all hope.

Graphics user interfaces were a mistake. Text based interfaces are almost always superior.

I'm not queuing up in an online store to buy concert tickets or the latest iPhone, I'm queuing up to buy local, organic, grass-fed, Angus beef. This is what peak granny hobbies feels like.

Today I learned that there are colorful solar panels. And the FC St. Pauli soccer club has a pride flag 🏳️‍🌈 made from solar panels on their roof. I want a rainbow flag on my roof to trigger all the ultra conservative old people in my neighborhood.

The sound of spring in Germany is around: Lawn mowers!

If – on this grey Sunday morning – you would like to read a dozen pages about using tail calls for fast interpreters, then I have Excellent News for you: www.mattkeeter.com/blog/2026-04...

There are at least six or seven different formulas (that I know about) for calculating the impedance of a PCB microstrip track, and they all disagree. What a wonderful world ...

I have complained a lot about Altium Designer in the past, but at least it can render correctly on high-dpi screens. Many other, very expensive, software still can't do this. I'm looking at you Ansys SiWave, KeySight ADS, or OrCAD X.

I searched "data center coloring book" because I was trying to decide if I should make one and found this, from a power management company, and I don't think I can top this www.eaton.com/explore/_pfc...

Go to GitHub.com and change your settings to not allow your code to be used for AI training. MicroSlop is truly going back to the old ways of being evil.

The best ideas are always hidden in the threads.

In this year of 2026 if you absolutely have to run your mobile, international event in America - and you choose to run it in Texas, Tennessee, or Florida, that is certainly a choice that reflects which of your members or employees you see as human.

Any reading recommendations to more thoroughly understand (specifically) Linux networking? I do have good reading on the lower levels of the stack.

After literally years of using Remote Desktop with atrocious performance, I have finally figured it out. Two months after buying a ThinkPad so that I can do CAD on my couch. arvid.io/2026/03/25/f...

Another team joins the "probably don't use Tokio Mutexes" club

It's 2026. We have 10 Gigabit ethernet. Yet, Remote Desktop over LAN still has a delay of several hundred milliseconds and renders at what feels like 10 FPS. That's option 1. Option 2 is snappy but is illegible because it has graphics artifacts all over. I don't get it.

Announcing the Zero Token architecture. Instead of burning AI tokens, you learn to think for yourself, and complete tasks using your brain.

The aftermath of cutting a stencil free of the JLCPCB frame. Mistakes were made and the stencil was ordered with the frame. It's now got a more manageable size.

Manual assembly without KiCad's iBom plugin is possible but pointless. Seriously, I've got some projects that are still in Altium (hopefully fixed by KiCad 10 and better delay tuning tools) which I'm now importing into KiCad to get an iBom. I feel like a caveman with just pen and paper.

Arduino completely sold themselves out. The embedded world booth had zero mention of their traditional non qualcomm offerings. A shame. #ew26

Fuel is gonna bankrupt me if it continues going up like this. One tank of the small car is now 110€. One tank of the big car is now 172€. One tank is the even bigger one is now 860€.

I’m reminded of this comic almost every time I check LinkedIn

First assembly job with my new(ish) JBC manual pick'n'place. Board manufactured by @aisler.net.

It's time for embedded world again. I'll be in town on Tuesday. Who's there?

4500€ for a MacBook Pro and it doesn't even have a charger. This is ridiculous.

Of all the f**king cursed projects to see on Reddit today, a rust compiler written in PHP has to be top, right? ::ping @tschundler.leds.social.ap.brid.gy @xconstants.bsky.social:: github.com/mrconter1/ru...

If you don't know what the Baochip is, you need to watch this: media.ccc.de/v/39c3-xous-... It's brilliant, and pretty darn impressive for something created by just two people.

Now, on a dev drive, with the performance power mode enabled, all av scanning disabled, and plugged into the wall outlet, I managed to get it down to 2m 14s. This is "only" 31s slower compared to the MacBook Pro. The M1 compile-time was no different if on battery or not, funnily.

Do check out setting up a dev drive: learn.microsoft.com/en-us/window... It uses a much lighter file system and improves perf. You still won't get linux fs speeds, but it's noticeably better.

It's unfathomable to me how someone can use a mobile Intel platform for any sort of serious work. And then use Windows on top of that, which makes everything even worse. The fs perf on win32 is still garbage. Compiling the same Rust project takes 100% longer on Intel vs Apple ARM64 system.

I wish more people would realize just how much superior macOS as a platform and system really is. When comparing my 5 year old M1 Max MacBook Pro to a brand new, late 2025, ThinkPad with similar specs (64 GiB RAM, 16 Core CPU), the MacBook still fares better in almost all accounts. This is sad.

saw a reddit comment on the lenghth of modern dev cycles earlier that stuck with me: "The PS2 had three Grand Theft Autos, GTA5 had three Playstations"

TIL that I have something in common with Linus from @linusmediagroup.com. We both own a fire truck because we both apparently are children that earn money and spent it on things we think are fun.

Is it too much to ask for a car that you don't have to take to the shop for repairs multiple times a year? Especially for a six-figure car that's ridiculous.

If AI made building new software so much more quick, easy and approachable, where are all the new killer applications? I haven't seen anything.

I double and triple checked the datasheet, and the timing looks correct. A quick test revealed that adding a 100kR pull down on CS fixes the issue. Professionally jammed between the pins of the connector.

2006: Less is more, don’t repeat yourself 2016: Beautiful code prevents technical debt 2026: trillions of lines of generated spaghetti code that generate other spaghetti code will save us

Managed to get the SPI display working after all. I disconnect the logic analyzer and suddenly it doesn't work anymore. I guess the added capacitance from the probes affected the signal so that higher frequencies were stable, when they aren't actually?

AI is still useless. Billions wasted for this. RAM prices are up because we can now draw wrong things.

Incredible work!

What do you connect embedded Rust with? For me, embedded Rust is massively generic programming, to the point where it's almost ridiculous. The following is an entirely normal struct impl block, like I have in many of my generic drivers. #rust #embedded

The D keyboard shortcut in @kicad.org to open the datasheet of a selected component is simply brilliant. This makes checking your PCB and/or schematic.

Seeing some of the old aqua macOS interface makes me really nostalgic. I loved that style. And it still looks great and modern. I have yet to update my MacBooks to Apples new glass interface, but everything I have seen so far looks awful.
