virtue3··on Testing a 1,000 player Minecraft server with Folia
I think EVE wins in this regard. But the sector ends up getting super degraded and going into time dilation to make it happen.

virtue3··on Sweden wants to build an entire city from wood
LEGO was one of the first ones I remember that did this. Almost all their promo material was pretty language agnostic if I recall. Even now the sets have multiple languages on the box
virtue3··on Android’s emergency call shortcut is flooding dispatchers with false calls
I ended up getting a wallet style case with a cover for this exact reason.

I'm not quite sure they are guaranteed to be deterministic across architectures either.

I think rounding up/down can vary across architectures. Mixing arm/amd/intel here should result in non-deterministic behavior potentially. https://en.wikipedia.org/wiki/IEEE_754#Reproducibility

Ah... I see. The game is using a software implementation of floating point maths to avoid this issue :). Smart. That in combination with the unified compiler should get you out of most of the trouble.

virtue3··on North Korean market prices suggest serious food shortages
I think you need to actually take a step back and realize how complicated the world actually is.

Brazil is one of the major exporters of food in the world. And they get most of their fertilizer from Russia. Russia is cranking up their prices because of the trade war being enacted on them because of their actions in Ukraine.

Brazil had also imported a ton of wheat from Ukraine before the war. And is full of people that couldn't really afford a 15% increase in price versus the over 100% increase in retail price of wheat.

Just ask google who the top producers of -fertilizer- are. You can't farm without it.

virtue3··on About GitHub’s use of your data
except you can't get free private repos anymore... oh wait...

Yeah they give you a lot more on the free account now, don't they? :/

It's fine, we can just develop AIs to find good content for us! /s
virtue3··on Building a Slack/Discord alternative with Tauri/Rust
The JVM being truly cross-platform was a bit of a lie depending on what you do.[1]

"Java is write once, test and debug everywhere."

Also the ui toolkits for JVM ecosystems are just not as nice to develop with. But I was pretty hardcore C#/.net back in those days so take what I say there with a grain of salt.

virtue3··on How Effective Is More Money? Randomizing Unconditional Cash Transfers in the US
"The data are most consistent with the notion that receiving some but not enough money made participants’ needs---and the gap between their resources and needs---more salient, which in turn generated feelings of distress."

I think the current title "Cash Transfers: No positive effect of cash – if anything, negative effects (ssrn.com)" is greatly missing the message here.

virtue3··on An Early Run-In with Censors Led Rod Serling to ‘The Twilight Zone’
I feel like TiVo actually opened up a lot of this and the nascent streaming available at the time (hulu/youtube?) is what kicked off the rise of actually serialized and episodic TV.

It is very funny having to explain to people why shows like "star trek: the next generation" basically had to reset everything by the end of the episode back into it's original state in order for syndication to work (episodes are basically played in any order aside from the few 2-parter episodes).

asphalt is already tar/oil anyway, wouldnt make up that much of a difference I'd think.
virtue3··on Show HN: AI generated Magic The Gathering cards
IMHO draft tournaments for "friday night magic" if that's still a thing were significantly better and more fun cuz of this.
virtue3··on Taking a break from social media makes you happier and less anxious
I think the nuance here might be in keeping your head still in the general news of the world but avoiding the things that cause "tribal syndrome" or anything with "keeping up with the joneses".
virtue3··on Ask HN: Free and open source distributed database written in C++ or C

virtue3··on A common sunscreen ingredient turns toxic in the sea – anemones suggest why
One could argue that the oil industries play to shift greenhouse gas emission responsibilities to consumers was pretty horse shit.

Especially since greenhosue gas emissions for the airline industry is about 3% of all greenhouse gas emissions.

Global variables in that kind of codebase might be -really- hard to keep track of how you are accessing and writing them :/.

This gets really fucking nasty when you're doing things like setting it to volatile and potentially accessing it across threads and you end up with a partial write and then doing a read, etc.

I'm sure the axiom of "it's never tested as much as we want" still probably applies here and that's slightly terrifying.

“Spaghetti code”: Incomprehensible code due to unnecessary coupling, jumps, gotos, or high complexity

Yeah that sounds fun. really fun. This is why I purposefully never work on any system that could kill someone. I just can't imagine being in charge of something like that and not wanting to go insane with knowing my code wasn't checked enough. or I wasn't careful enough.

virtue3··on SELinux is unmanageable; just turn it off if it gets in your way
when it comes to JS libraries I'm usually a lot more interested in how good their testing is. Code quality can be very subjective in some areas. But if the dang library doesn't have a lot of good testing then I can't really trust any updates from it :/
virtue3··on A naked skydive inspired a way to keep pilots oriented in flight
You are incorrect.

The MCAS system was built to work on a very buggy angle of attack sensor. They are notoriously unreliable. The max kept one on each side of the plane (the airbus equivalent has 3 on each side). Further compounded by the fact that the (this was true at the time and theyve joined systems now) pilots computer only used the left side of the plane instruments and the copilots computer only used the right side.

So no. Boeing fucked up in the first place by trying to stealth fix a hardware problem (stalling at a new lower angle of attack in the "same model airplane") with software. And then lying through their teeth about the impact of this.

The equivalent military 737max with MCAS simply allowed the pilot to more forcefully adjust the flight control stick to turn it off. So they knew better.

Companies attempting to skirt legislation in the face of better profits is always going to cause issues here.

The entire max disaster was an attempt by management at Boeing to get pilots to be able to fly all 737s with basically no retraining.

virtue3··on The ‘uncured’ bacon illusion: It’s cured, and it’s not better for you (2019)
CO2 is one of the few gases our body can detect. Because C02 build up in our lungs means we aren't performing respiration.

I believe we can't detect C0 and things like N0 so they just straight up kill you once you pass out from oxygen deprivation

virtue3··on Analyzing Weapons of the War in Ukraine
I think once the Russian air force is actually pulled into the war it's going to be significantly less effective. And that's what Ukraine is really worried about.

I'm not 100% sure on why Russia is holding back their air force in this conflict but once it's engaged it's going to go very poorly for the Ukraine soldiers if they don't have a way to assert control of their airspace.

virtue3··on Taiwan hit by widespread power outages
No modern military would do a ww2 style beach landing. It's why we retired battleships.

You send in naval air forces to obliterate defenses on shore then send in marines.

This is probably why China is deeply invested in long range fighters (their modern fighter has significantly more range than US ones). And aircraft carriers as of late. That and enough surface warships to defend said carriers.

virtue3··on Why I will never buy another Samsung device
worked for a company doing apps for smartTVs. They all do it. Incessently. I made ad games that would pop up when the system recognized a certain ad was playing. you were supposed to be able to opt out of this but LG got busted in the UK for not listening to that option. This was back in 2013 era. It's worse by now I'm sure. They'd straight up send a screencap of whatever was on your screen every second for content recognition. Terrible shit.

virtue3··on Green steel without green hydrogen – can it work?
It is not trivial to store hydrogen. It takes a very large and expensive tank to store it at any practical level.

And it has a tendency to leak through most materials.

https://planetforlife.com/h2/h2swiss.html#:~:text=Hydrogen%2....

"B&E estimates that a liquid hydrogen tank designed for automobile use will loose about 5% of its capacity every day, which is to say that all of it will be gone in 20 days. Losses of this magnitude are acceptable for, say, a taxicab fleet, but unacceptable to most people."

Also new to me that it's a greenhouse gas: "Hydrogen cannot be vented to the atmosphere because it is an explosion hazard and because it is a greenhouse gas. The vented hydrogen must be burned. A continuously running gas stove with one burner set to "medium" would do it."

virtue3··on Ask HN: Am I being instructed to do something illegal? (DEI hiring practices)
It's not racism it's prejudice.

"According to the sociological perspective, members of privileged groups can experience prejudice, but their experience will be different than the experience of someone who experiences systemic racism."

One could argue that being in the majority you would have an easier time getting a lateral promotion than someone as a minority.

virtue3··on IBM’s Watson Health is sold off in parts
It's kind of similar in some ways to the traveling salesman problem. Which is not considered np-hard.

"How do you get to tokyo from paris", the cheapest, the shortest time, the least layovers, add a stop in X, etc. Not that easy.

Then you have to remember all the stuff under the hood like how are you caching all that information, how do you actually register the sales of all those tickets. Are they in your flight alliance? Are they goign through your regional airline systems too?

I would never want to touch that stuff. Way too hard. Way too many legacy systems powering it too, probably.

Which is now owened by google and probably powering google flights lol

virtue3··on Activision Blizzard pushes out dozens of employees over workplace misconduct

So when we see it being limited it freaks us out.
