It is 100% a huge deal to be able to "listen" to data like this when you do fast digital/analog stuff.

It's from the late 70s, so for some things, there's a world where you could feasibly have used discrete logic (instead of CPUs) to display things, and being able to send BCD means a lot less transistors/logic!

James Munns @jamesmunns.com · 1h

A thing to remember is that some avionics (and their standards) are OLD. In some cases, it was just much easier to send BCD to allow for simpler displays and such.

Ben Eater doing an overview of Arinc429 is definitely a surprise. A429 is one of those things that was a huge deal when I worked in avionics, but used basically nowhere else.

It's a fun little 32-bit-word differential serial protocol used in aircraft electronics :D

it's true! though being able to commit your "core work hours" rather than "spare free/personal time" to work on project definitely helps to not *cause* the burnout, IMO.

I find money is fairly motivating as well, to be honest.

Please do not attempt to "motivate" open source maintainers with "community encouragement".

Should out to bahn.expert, literally the best train status website for Germany. Simple website with literally anything you could contextually want to know (all the stops, time at stops, platforms of stops, layout of trains, even *datasheets* for the train configurations of routes). Loads fast.

this is interesting because it lets you access basically the whole door panel (the one I had was probably like 1x1 foot, maybe a bit wider than tall)

"door in door" is what I saw in more recent models

yeah, that fridge was clearly old when we were renting that place, but I've not seen any one since that had it. I'm definitely jealous too.

I'm sure it's just a cost thing: it's an extra perimeter to seal, an extra set of hinges, an insulated door, etc. Would be a nice premium feature tho.

tbh, I'd probably take that over a built-in water dispenser (and a tv lol), same for getting ice cubes out of the fridge if it was a side-by-side unit.

The door-in-a-door even had a cover on the inner side (sort of like the butter penthouse has), so ideally almost NO temp loss to the core fridge.

I had a fridge in college (in the late 00s, but the fridge was old, probably late 90s) that had what I think is called a "door within a door", but basically JUST big enough to get to subsection of the door shelving, which made it perfect for grabbing milk or sodas/beers without a full opening

I'm fairly certain both the RP2040 and RP2350 only support USB-FS.

Oooh does new kicad have colored ratsnest wires? Or is that a hint you could always do and I just didn't?

j/k, I must have caught you right at a bad moment, now it totally loads, and pushing works fine. Hopefully it was just a little hiccup, or since I hadn't logged in to tangled directly for a bit and something was migrating or something :D

James Munns @jamesmunns.com · 2d

Is there still some kind of outage going on? tangled.org/@jamesmunns.... is something I've pushed to, but it currently shows as an empty repo for me, and trying to push shows:

exec request failed on channel 0
fatal: Could not read from remote repository.
