I totally understand why they would do it. For awhile the shuttles were running machines with 256kB of RAM, I forget what architecture.
That's not code you want to revisit. That's code that goes through mountains of approval, documentation, testing. It's elephanting expensive to develop, and quite difficult to do correctly.
I haven't watched the video, but I run into a smaller version of the same problem with medical/clinical software.

I don't think I want to see any ifdefs in such software.

How do you stub missing/incomplete physical components for developing without ifdefs?

That sounds like a bad idea when dealing with the systems indicated.

It's SOP, it actually allows to build and test the software alongaside the hardware. Otherwise you'd have to wait for all the hardware to be finalized and in production, then start writing the firmware and the software over it... with the potential of discovering integration issues, in that case the hardware must be modified and the software development halted until everything is in production again.
Nope, software starts on its own and everything not yet existing is stubbed. Meanwhile all the development, testing and most importantly validation that can be done without the hardware is done.

Which is fine for the early stages of the development of commercial types of software, but when a rocket is about to be launched, that would not be an ideal situation.

8086. Sometime in the 2000's they went on an ebay shopping spree for old embedded systems they could harvest spare CPUs from.
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, weighing all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

Just a guess without seeing it...
because they are more reliable than any other current hardware?
M.D.V. 
If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?

Dunno, I am rather lucky, working on the cutting edge technology the 8051 core provides.

Ah, little endian and big endian processor handling?

In this case, yes. Apparently the PowerPC has a specialized instruction for what that routine does.

Hey,
If you are looking at a game/graphics library I just want to point out that the Xbox 360 uses the PowerPC instruction set. In fact I think Nintendo Wii-U was using it right up until a few years ago. So not really archeology.

Wow, I did not know that. That's interesting. I love when I can learn stuff. Thanks!

Darren Korb - God of the Dead[^]
A soundtrack this week, of one of the best games of 2020, Hades.
I remember the positive reviews from last year, but I'm a bit late in picking this up because I had doubts as to whether this would be my kind of game.
Then I played it at a cousin's house a few weeks back.
Let's just say it's my kind of game 
Unfortunately, I suck at it... Haven't heard this particular song all that much, as I rarely make it to the final boss 
You basically play the same thing over and over, trying to escape from the underworld, getting a bit stronger each escape attempt, until you finally make it.
Made it out a few times and this song makes the final boss all the more enjoying 
The entire soundtrack was composed by Darren Korb and he also composed other Supergiant games, so I'm guessing he's their house composer.
So anyway, I can recommend the game and the entire soundtrack (which features lots of calmer songs as well, this one is actually the most metal song on the OST).
Game of the week, sound of the week!

Very nice! Here's Obi-Wan Kenobi on the drums: Apparat dans Passengers
-- and a halfway nice mix of a band I usually find somewhat boring: Kraftwerk Megamix. There are some boring parts in it, but better than the past stuff I've heard.

I know Apparat, I think mostly from their work with Modeselektor as Moderat.
Good stuff

Agreed there 
Good stuff when you're in the mood for it though.

The game is a masterpiece, and the soundtrack is great too!

I have heard good things about this game but have yet to take the leap.
This might very well be the final nail in the coffin that sends me to the underworld.

You thought Blizzard had done enough miss-step of late, right?
But now they are snubbing their Australian players!
There is a new season for Diablo 3 starting this Friday night. But us Australians have to wait Saturday morning! Australianism!

Hmmm,
Is this the gamer version of trickle down economics? You know... with Australia being 'Down Under' and all that.

I know all about that, learned by watching Crocodile Dundee!

If you can keep your head while those about you are losing theirs, perhaps you don't understand the situation.
