Fair points, I hadn’t considered the economic side of it; or even the mass beyond how it affects lift.

True, I hadn’t considered the economic angle at all!

Also for unmanned aircraft, using helium instead of hydrogen is just crazy
Is it? Hydrogen is about half the mass of helium, but the trick is what you’re displacing to generate lift.
1 cubic meter of air is around 1.2 kilograms, depending on a variety of factors.
1 cubic meter of helium is around 0.18 kilograms, displacing the atmosphere to generate about 1.02 kilograms of lift.
1 cubic meter of hydrogen is around 0.08 kilograms, displacing the atmosphere to generate about 1.12 kilograms of lift, a shade under a 10% increase over helium.
That can be significant, depending on other engineering constraints; but is it “crazy” different?
(Numbers will vary with temperature and pressure, back of envelope calculations, etc. etc.)

- Comment on Marketing Doesn't Work on Nerds 4 weeks ago:
Maybe - but the marketing that won’t affect you isn’t what you need to worry about. It’s the parts that do still work on you need to be careful of - and if you assume nothing will ever work on you, you won’t even notice when something does take. Whether that’s buying a trinket that doesn’t actually make you happy, or joining a group that turns out to be a cult.
Always better to assume you can be manipulated, and check in with yourself periodically.
- Comment on Marketing Doesn't Work on Nerds 4 weeks ago:
This… strikes me more as self-aggrandizing than informative.
Yes, many technical folks are put off by certain marketing tricks. Good marketers just use different techniques when targeting people in this market, when they bother to at all.
We’re not immune to manipulation; and thinking that we are makes us more susceptible to it.
- Comment on Why I Ditched Spotify, and How I Set Up My Own Music Stack 1 month ago:
Just went through this with both kids… The word “need” always implies a goal. “I need x (to do y)”. Without context, the goal is generally either survival, or more often, comfort: “I need a drink.” “I need a break.”
When you’re speaking in the context of doing something, as superglue was, that becomes the implied goal. “I need those recommendations to automatically populate (in order for my wife to be comfortable using this)”.
- Comment on That's an impressive drop. Any ideas why? 1 month ago:
Ah, okay, I didn’t see that from the comment tree. I don’t think that’s gender specific though; if anything, women seem even more likely to be rejected due to age than men. And there’s also other confounding factors with age: as your cohort ages, they get paired off, and have less time to devote to dating, and do have a somewhat decreased sex drive pushing them out there. So the dating pool is quite a bit smaller - even if your looks didn’t diminish, it likely won’t carry you as far as your dating pool ages regardless of economic factors.

Ever heard about STD rates in nursing homes? There may be a factor that’s correlated with age, but age itself doesn’t stop sex, or even slow it down that much.
- Comment on FTC chair Andrew Ferguson warns Google not to filter or suppress emails sent by Republicans over Gmail 1 month ago:
Ahh, fair point on the source. I should probably let myself wake up more before posting :P You’re right though, it’s a weird “study”… feels more like a quick test I’d run locally to check my processes than anything with real rigor.
- Comment on FTC chair Andrew Ferguson warns Google not to filter or suppress emails sent by Republicans over Gmail 1 month ago:
… doesn’t it say Republicans claim similar spam from Democrats got through?
My main takeaway is the Republicans want to block Democrat messaging, and via projection, assume Google is doing the reverse.

I feel like regular patrol cars might work like this already - who’s going to blow past a cop driving down the road?
- Comment on Teddybears - Punkrocker 1 month ago:
Okay, that’s the disconnect - you do not need to dehumanize someone to consider them an enemy. Police and militaries often do so, because it makes people easier to shoot; but it is not necessary. And the cognitive dissonance of dehumanizing their targets leads to a lot of the issues soldiers face later on. (And oh, hey - look who’s become rife with fascists!)
Fascism absolutely needs stopped. It and the people supporting it are an existential threat. But the way that fascism starts out is by treating some people as less than human, as something other. And if you have to make an enemy a nonperson to beat them, then the groundwork is already laid for fascism to return with the next generation - after all, you’ve just shown dehumanizing people can get the results you need, right? Why not make a habit of it?
- Comment on Not stealing 1 month ago:
I think that really depends on the kid too. I’ve had one behave like that fairly regularly until he grew out of it; the other will get upset rarely, and never in public.
The post read to me as the dad cracking a dry joke, not actually making an excuse.
- Comment on Teddybears - Punkrocker 1 month ago:
Who’s arguing against violence? I’m saying don’t dehumanize them. Humans are quite capable of being monstrous and horrible all on their own.
Absolutely fight back against the fascists! My grandad did, and I think he’s a fine example to follow. He didn’t have to treat them as something other than people to do that, though. He just treated them as the enemy they were.
- Comment on Teddybears - Punkrocker 1 month ago:
I’m not talking about name-calling. Go hog wild with that, it seems fairly effective.
I’m talking about dehumanizing them. Deciding that any means that will end them is justified. Treating them like feral animals. Harvesting their organs for profit, like outhouseperilous suggested further up. That’s what I’m pushing back on.
- Comment on Teddybears - Punkrocker 1 month ago:
Right - fight them! Resist them! But do not let them push you into being inhuman yourself.

At this point, my best guess is these guys just don’t actually read any Punisher material.
- Comment on Teddybears - Punkrocker 1 month ago:
Man, bit of a tangent, but even as a fast thought experiment, Thanos’s idea was bad. Just his motivation was (debatably) good.
The problem is, the vast majority of species populations can easily double in a generation, given plentiful resources - and plentiful resources was what he was aiming for! Even if everything went exactly as he thought it would, he’s just kicked the can down the road for one generation.
- Comment on Teddybears - Punkrocker 1 month ago:
Whether they deserve it or not, I won’t dehumanize them; because I don’t want to become someone who dehumanizes others.

Pretty sure this was just a play on the similar pronunciations between “Epstein files” and “Israeli pedophile”. It didn’t read to me as outrage bait, but a joke that keeps the Epstein file conversation alive as a side effect.

- Comment on How often do you take him for a walk? 2 months ago:
Raised properly… to not go exploring every nook and cranny? Personally, I’d rather let them be curious, and take steps to be sure they can explore safely.
Rather than thinking of it as a person on a leash, compare them to strollers. You see kids in strollers all the time; they’re strapped in, don’t really have any control over what’s happening, and kinda have to be passive. And they’re generally pretty happy like that for a while. But, not every kid is alike, and not every parent has the resources and help they should have. A leash lets a kid run around without the stroller, without getting into trouble where their parent can’t immediately see what they’re doing. It’s a step between being strapped into something, and running around freely.

You don’t usually feel better a few seconds after a concussion, do you? Even with lots of hugs and kisses?
- Comment on Incident 2 months ago:
I’m not sure I agree. 10 or so kids lets them get a lot of practice socializing, with 3-4 caretakers. Without a tool like this, it’s really easy to miss that nobody’s needed to change little Mikey’s diaper today - but that’s information that can be important for them and the parents to know.
- Comment on Schools are using AI to spy on students and some are getting arrested for misinterpreted jokes and private conversations 2 months ago:
Teachers are generally awesome. But school boards and superintendents are almost stereotypically control freaks; and that’s who sets this stuff up. There are plenty of good ones too, but it’s not nearly as selfless a group as teachers.

It seems like, if they’re publicly denying responsibility, Steam and Itch now have legal cover to restore everything.
I’m not a lawyer, etc. etc., but don’t public statements from these kinds of entities inform how these clauses are enforced?
