Current defense worker here:

Was talking with a coworker recently about how ITAR/EAR rules are hilariously out of date. Basic IMUs coming from China these days are good enough that you can establish a reasonable dead reckoning nav to where those parts of the munitions list are just defunct. Shit I did that in college ten years ago with high power rockets and things have only gotten better.

The new proposed regulations over AI chips are also wildly misguided and demonstrate how Congress/Executive branch have no idea what the tech even is. The top of the line chips today are needed for LLMs, fast fixture acquisition and tracking can be done on a way less powerful piece of hardware that new regulations will fail to stop (that's even assuming that the bans would have worked in the first place, which they won't)

I mostly listen to just LTTs podcast WAN show and on there Linus has said several times over the years that he doesn't like having his kids in videos, he finds it grimy and takes a real issue with family YouTube channels since the kids don't have a say.

His family only appears in videos when they ask to be in a video, and even then he makes the kids do the pitch so they have a real vested interest in wanting to be in the video.

That's why his one son has been in several videos, one daughter has been in a couple, and the third I think was just in one video years ago. The videos can be a bit clunky because while the adults in the room try to make a video engaging and interesting there's only so much they can do. Linus has also stated that he'd sooner let LMG as a company fold than just hand the reigns to his kids.

The clunky pool and yard video iirc was a case of the business development team signing a brand deal and the video production team not knowing what else to do

I'm a gun owner, I enjoy shooting, and I agree that carrying a rifle is more terrifying than a hand gun here.

It's a power play, and a fantasy attempting to become reality.

You carry a rifle like that because you want to be seen with it. You want others to fear you because they see that you have the power of death in your hands. You want to feel like you're the big man in the situation, and if that's your line of thinking, I'm more inclined to think that you're the type to escalate a situation where you'll feel justified to use that power of death and and actually shoot someone.

If you were actually concerned about defense you'd carry a small pistol that you can grab in a moments notice, action it to put one in the camber, aim, and pull the trigger. A rifle like that you're not carrying loaded, maybe you have a loaded magazine in your pocket but you're still several seconds away from me able to actually shoot it. It's bad theater

After you beat Ganon in OoT, as he's spinning in the void, there are dialogue boxes of "CURSE YOU ZELDA! CURSE YOU SAGES! CURSE YOU insert name here"

Since the game just pastes your name in directly, the capitalization will be wrong unless you name yourself LINK. Now, on every playthrough I do of any Zelda game I name myself that because when I was a teenager it bothered me that the capitalization was wrong in that one instance and I thought it was funny to effectively make all characters shout just the name

Tears of the Kingdom does have Palpatine Ganon say Links name

A link to the past might have him say the input name (the randomizer has ruined my ability to remember what is and isn't in the base game), but in all other titles I don't think Ganon says the players name

Fun fact:

Internally they switch between imperial and metric all the time. The broadcast is in imperial for US viewers.

Sauce: once upon a time I worked there

Carrying forward technical knowledge is definitely a big help. I suspect that's why Atlas V was able to pay for itself because the booster was so similar to Atlas III which itself was similar to Atlas II.

The satellites I work on play this game constantly. Mission A and B both use the same underlying tech that needs to be developed, but mission A is first. So we charge mission A with all of the cost and then mission B looks a lot cheaper on the books

I work in the aerospace industry, mainly to satellites these days but I've worked in launch in the past and have plenty of friends who have as well.

That 450 figure is probably all of Falcon 9s development which has gone through several design iteration cycles. Industry rumors point to a new Falcon 9 booster being around $50 to build and a million or two to refurbish on average. The re-use is saving them a significant amount, but the upfront design cost was just so stupid high.

It's also worth noting that Starlink supposedly launches at near cost meaning little profit for each of those, but then SpaceX turns around and prices Falcon 9 close to Atlas V for government contracts (90-150m total price so probably 60m profit) and gouges people on Transporter (they're almost certainly pulling in 150-200m on each of those)

Nuance on the Internet? Not allowed, fuck off

Senior embedded C developer here in the US. I can speak first hand experience at people applying to be on my team that have reasonable sounding experience and then collapse under interview questions.

Everything else you said applies here too, legally we don't have repercussions for firing someone quickly (once had a team member for two months), but a healthy org will try very hard to get hiring right because it can cause pretty bad morale to see a revolving door and there is a massive brain and resource drain having to constantly be training new people.

Smaller businesses or privately owned businesses with a smart owner do.

Large publicly traded companies are sustained by a perception that an investment in or loan to that company will pay off in a higher dollar amount in the future, so if the perception becomes the company is shrinking then the investments and loans slow down which makes the perception worse, you get that feedback loop which turns into the death spiral.

So the bigwigs at the top of these companies have to be professional liars and gamblers to change the perception and make it look like everything isn't just fine, they're doing great! The line must go up.

Yup, sometimes it's too easy for me to just slip into work mode when talking about this kind of stuff and I don't elaborate enough. Thanks for stepping in.

Based on industry rumors I believe the Orion capsule control computers are running VxWorks (I've heard that maybe a few boxes are using RTEMS?) All of that source code would have been reviewed, audited, and tested to hell and back.

The day-in-the-life stuff for the astronauts is entirely believable to be Windows. The risk of it failing is so low (medium probability, low impact), it's what they'd be familiar with, and it's part of daily life at NASA anyways. Linux is no better when it comes to safety critical components and the astronauts almost certainly wouldn't want to be dealing with Gnome's... uniqueness....

I have not worked on human rated launch vehicles, but I've been adjacent to them, saw what went into them, and a few close personal friends have worked it.

Anything that can jeapordize the safety of the crew must go through a rigorous independent validation and verification process that takes years, software included. No shot a Microsoft product was even in consideration for those systems.

Being in industry I find it crazy that so many people are freaked out by this. Astronauts have email, they have tasks and schedules and reports to make. Why would NASA reinvent the wheel on a task/schedule manager when the ground operators and astronauts are already used to using Outlook.

Distributed vs centralized has no impact here. It's all about excess power across the entire grid.

Sure, the solar system I own generates a few kilowatts and if I'm home cooking or running AC, I use almost all of it. But if I'm not home, my AC is off, fridge isn't running at that moment, all of that power gets dumped onto the grid. My neighbor's down the street do the same thing, their next door neighbor, the houses all in my neighborhood, and across the entire city, we're all doing this. A hundred or thousand homes generating excess few kilowatts adds up to megawatts

Sure, the energy company pays a pittance for the energy I put onto the grid, but it's still payment. I'm not gonna put a dummy load on my house to not export power

I too came in here thinking about outer wilds.

The controls are less realistic than you think, because they attempted to have the ship correct itself but it constantly fought me. I program spacecraft for a living, I know how the orbital mechanics and movement in 3D space works, and they made it super frustrating it made me rage quit the game for years. I only finished it because a close friend wanted me to experience the story.

For me, the story >!was the games weakest point. Putting together the history and the question of "what happened" was cool, but the dialogue was insufferable, I hated reading the story walls and having to string together the order things were said. Then to finally put everything together, get a half baked story about being marooned on effectively a desert island and it ends with a shrug and "yup, everyone died, you too"... Man fuck that.!<

Spacecraft software engineer here:

They are and they aren't. Radiation causes problems in terms of Single Event Upsets where a 0 turns to 1 and a 1 turns to 0 for a super tiny second. CPUs take some amount of time to let the transistor circuit stabilize before moving onto the next instruction so if an SEU happens in the beginning of this period it won't have any downstream effects. Like a bump on the road.

Memory however is vulnerable to this tiny amount of time and can flip a bit to a different state than it's supposed to be, but both are solvable problems with hardware and software based solutions, with ECC being the most common.

The other major problem is Total Ionizing Dose. Put silicon based semiconductors in radiation long enough and they will break down, and there's no real hardware or software based solution to that. But it takes a long time
