I shouldn't have said that. My 3 year old Mercedes decided to die on my when trying to drive home from personal training. Turn the key. Nothing works. No ignition. No motor start. Nothing.

Modern cars are absolute garbage.
Some people dream of driving a new Mercedes. I dream of getting rid of my new Mercedes and buy some 90s Mercedes. They really have lost it. Absolute garbage cars for a six figure sticker price.

Set to zero again. It's been quiet for a while because I disabled updates, but I made an update recently that reverted this again.

I hate Windows.

How can anyone use this OS for serious work?
Days since a Windows 11 forced reboot lost work: 0

Somehow I expected the SMT stencil frame from JLC to be somewhat smaller and not the size of a DIN A3 picture frame.

My toaster oven has an exposed SWD header. Are you thinking what I'm thinking?

Raise your hand if you ever inadvertently caused a 2+ hour outage (which was impossible to fix in a deterministic manner) due to DNS misconfiguration. #itwasdns

I've invested (read: wasted) lots of time learning exactly how LLMs and "AI" work and they suck even more than before I did that.

Nice try at polarising tho m8
There are basically only two positions in the debate about AI.
1. I’ve barely invested any time in learning how to use it effectively. AI sucks.
2. I’ve invested in learning how to use this tool. Holy cow, it’s transformational.

Position #1 has lower barriers to entry.

Anyone got some suggestions for a good toaster oven to be transformed into a reflow oven?

On the weekend, I used my new stereo microscope for the first time on an actual soldering project.

God damnit, this is so much more relaxing compared to squinting over the PCB with magnifying goggles (or without any magnification).

Worth every penny.

Good. Let's kill it.
Today is a day when arts degrees are worthless, but the product of those degrees is so valuable it would kill an entire industry if they were made to pay for it.
Nick Clegg says asking artists for use permission would ‘kill’ the AI industry

And, I did it again. Why do I not learn?
Why did I use 0402 components, though?

In Deutschland wird jetzt 1 Mio. Euro aus Steuergeldern in Werbung für das Weintrinken investiert, um unsere junge Gesellschaft dazu zu animieren, mehr Wein zu trinken. Kannste dir den Scheiß nicht ausdenken.
rvgt.ch Reto Vogt @rvgt.ch · Apr 29
Vor allem Junge trinken weniger Wein. Das ist "besorgniserregend", heisst es vom Bundesamt für Landwirtschaft.

Ich mach dann mal me Guttere auf, ich will ja nicht so sein. 🍷(Ist aber ein Griechischer 😎).

“Opt in” will be persistent, annoying calls to action that get in the way of everything, as is tradition.

Spotify hasn’t been a music service for years. It’s just another tired SaaS, out of ideas, and doing nothing particularly well.
Spotify is partnering with ChatGPT

• Will personalize music and podcast recommendations

• Available on an opt-in basis

What makes a std Future non-Sync (i.e !Sync)?

My dependency injection framework requires futures to be Sync because they're constructors and might be called from any thread (as well as possibly concurrently).

Some libraries create !Sync futures and I'm struggling to find why.

"Every heartwarming human interest story in america is like "he raised $20,000 to keep 200 orphans from being crushed in the orphan-crushing machine" and then never asks why an orphan-crushing machine exists or why you'd need to pay to prevent it from being used."

You were looking for traceability tooling in Rust, weren't you? I dimly remember something from a podcast episode. Are you aware of duvet? I just stumbled upon it (internally). github.com/awslabs/duvet

When constructing tuple structs, you can use curly braces with integer keys. These are identical:

let x = MyType(1, “hello”, true)
let x = MyType{1: “hello”, 0:1, 2:true};
what's a bit of obscure rust/rustup/cargo/crates.io lore that you know?

This is, unironically, very pretty.
Together with Corintis, Microsoft is working on a liquid cooling based on microfluidics methods. Microfluidics could get datacenter chips to run at a higher efficiency and makes per package TDPs of 2+ kW even possible.
