I have assembled the original ErgoDox, that I bought ten years ago in 2015 and assembled incorrectly. Until a couple of months ago I was missing a good solder sucker and hot air to desolder the switches and reflow the bad joints.
Incredibly, it runs the same software as my newer ErgoDox EZ.

Scanning and parsing of the part barcodes from electronics part suppliers (Mouser, DigiKey, Farnell), so that I can easily and electronically manage my inventory of parts (and most importantly, record where I stored them).
Next step, getting order in my inventory.

This Chinese manufacturer of a water spray bottle was apparently fed up with their customers asking for the impossible.
The stupidity required to think something could spray literally forever is unfathomable to me.

Hobby Programmer is good. I've only triggered C++ programmers by claiming C is better. I think I had a similar badge at CppCon.

The folks at goodenough.us have a physical guestbook that prints entries on a thermal printer. So I drew (badly, if I may say so) the @rust-lang.org logo and it was print out. #rust

This funnel might not be a great funnel, but it's a decent funnel.

The question is, what lead to the layoffs? I don't know for certain, my source mentions Dave Herman and Brendan Eich being the two highest positioned Rust believers inside MOZ. brson.github.io/2021/05/02/r...

Rusts `const` and const generics just aren't there yet. I've been trying to generate USB HID report descriptors with purely `const fn` and some magic, but I've failed.
Back to macros.

Interestingly, all the Rust Cookbook links have been broken over the weekend and now return a 404. rust-lang-nursery.github.io/rust-cookbook/
It was somewhat abandoned before, but now it's completely dead.
RIP.

It's snowing outside. I'm sitting in a rocking chair in front of the fireplace, getting hot feet while working on some prototype in Rust using Embassy for a Bluetooth split keyboard based on a Nordi nRF52. At the same time, my girlfriend is next to me knitting wool socks. I'd be good at retirement.
