Sudden power vacuums are often filled by the most opportunistic individuals in human culture. People who are frequently more concerned with personal gain over the collective well-being of the group. It's why assassinating heads of state usually just makes the situation worse.
Plenty of people stepped into power vacuums not to make themselves rich but to save their nation Napolean, Tito, Cincinnatus, arguably George Washington.
It makes sense. Convincing someone to go kill other people so they can take their stuff and rape their women isn't that hard. The personal benefit is front and center, it aligns easily with human nature.
Convincing someone to go kill other people so you can get their stuff is a lot harder. You have to get creative with the reasons, and even then you had better be giving those fighters their cut unless you've really managed to get them fully committed to whatever excuse to made up. It helps a lot if there is some kind of wedge issue you can exploit, which is where religion and ethnicity come in handy.
The term of art is Profit Taking. When you cash out your reputation to make a big quarterly profit. Did they also slash the research and development teams? Classic VC behavior.
The fact that the average person is seemingly incapable of detecting LLM text drives me insane. Every aspect of that article screams LLM. The tone, the punctuation, the sentence structure, the overall structure, it's so incredibly obvious. But the average person really is oblivious to it.
why?
Before comments about LLM I didn't notice this. After I compared pre-LLM posts and post-LLM and looks like AI was used to write/edit this article.
But.. why should I matter? Why my ignorance of this fact insane you?
The incredible part about this is because their backend is all TCP/IP they were literally exhausting the ports by leaving all 65k of them in TIME_WAIT, and the workaround was to start randomizing the localhost address to give them another trillion ports or so.
This is a pretty interesting solution. I could see how this could useful for certain kinds of problems (as part of a ddos attack mitigation for example).
The good thing about nostr is that, contrary to popular federated protocols, your identity is not tied to any single server, you own the keypair to your account, so you can continue using it just fine even if some relays experience a downtime.
This presupposes that there are no alternatives to helium for off world exploration. Would be interesting if warp drives were real but required vast amounts of helium to operate with no substitutions possible.
It becomes a larger problem as the world moves away from fossil fuels like natural gas.
I'm not a chemist but are there really no alternatives? Running fusion plants to make helium seems very unlikely to become cost effective, but it would be quite the sci-fi future if we filled party balloons by bombarding hydrogen with free protons.
I guess there aren't any easy molecules to break apart to get helium either since its a noble gas. No hydrolyses type solutions because there aren't any molecules that incorporate helium. I guess radioactive decay, but even that is ultimately limited over long enough timescales.
The article itself spells out several alternatives to buying continuous amounts of Helium: high temperature semiconductors and zero boil-off systems that don't require a continual supply.
All these "we're going to run out" stories pretend that engineering cannot adapt to changing cost structures, which is just total nonsense.
Sure, there is nothing that can be directly substituted for how we use Helium today, but clearly we're using Helium inefficiently today and the answer is that once markets force us to change, we will find more efficient ways.
There are many cases in the news of accidents with sometimes a large number of party balloons filled with hydrogen or other flammable gases.
One of the larger episodes was in 2012 in Armenia, where thousands of balloons exploded during a meeting, injuring 154 people, of which 4 seriously (the video is of poor quality): https://www.youtube.com/watch?v=jWEm2sS7Dw8
a party balloon - say a cubic foot - is about 2g of hydrogen. Involves 16g of oxygen. So we're talking 18g of very fast burning, borderline detonating mass. Releases 240 KJ of energy.
To compare the hand grenade - 60g TNT https://en.wikipedia.org/wiki/F-1_grenade_(Russia) - releases the same 240 KJ of energy.
I had a science teacher that did this in class, then taped a match on the end of a yardstick and held it under the balloon. They made quite a bang. I wouldn't want to be right next to it when it went off.
While hydrogen-air mixes explode really readily (outstandingly wide flammability and pretty wide detonation range), and the energy released is considerable for the weight, the actual explosion does not produce a particularly high overpressure wave.
That's because the starting density of the hydrogen air mixes at near atmospheric pressure (such as in a balloon) is pretty low. Also, the balloon does not significantly contain the explosion, which reduces the danger a lot. I would not want to do it in a glass container.
Along with the other commenter, I'll add that a classroom is usually a lot bigger than a home dining room or other domestic party locations. That size also helps things dissipate instead of reflect. Not sure by how much but I'm sure it does something.
My chemistry teacher told us how once when he ignited helium in a test tube, the tube broke and he ended up with pieces of glass embedded in his skin. The students had face masks and he was looking the other way "just in case" for this "safe" experiment but he could have easily been blinded.
Things can always go wrong. We probably shouldn't strive for 100% safety because they we'd spend our lives in a padded cell. But we also shouldn't assume things are safe because they're common or routine.
We did this. One balloon with plain air. One with pure hydrogen. One with 50/50 hydrogen and air. The one with pure hydrogen popped closer in magnitude to the pure air than it was to the 50/50 mix.
ETA: I may be misremembering, the more I think about it, the more I recall that we did not use air, we did use pure oxygen. Not like it was hard to get (and we had lots more interesting stuff than that in the lab, this was the 80s...). But the outcome I do remember. The entire point of the experiment was to examine the difference between the individual pure elements and the mix. We expected the pure hydrogen to be far more interesting than it turned out.
Pure hydrogen in a balloon produces a low, loud, very satisfying bang. Completely different from a sound of an air balloon popping. Here is a video from a very good Royal Society of Chemistry demonstration series on various unusual combustion process:
Hydrogen mixed with air or with oxygen produces an ear piercing supersonic detonation, exceedingly loud and unpleasant. Not recommended for demonstrations.
As a kid I took a lot of classes at the Lawrence Hall of Science in Berkeley, which was paradise for fledgling nerds. On the last day they would have a little closing ceremony with some cute little science experiment. One of my favorites was "Going Out With A Bang".
The instructors would bring out a helium balloon and a candle on a meter stick. The balloon goes pop, huzzah.
Then the twist. "Hey, wanna do it again?" All the kids would be like "meh, I guess?" They would then bring out a balloon full of hydrogen (maybe some oxygen too?). It would look identical to the first one, floating there tethered to the lab bench.
When the candle hit the second one, it made a white flash and a really sharp BANG. It was an order of magnitude louder, and you could hear the transient bouncing off the walls and echoing in the halls. It made an impression.
> It becomes a larger problem as the world moves away from fossil fuels like natural gas.
I actually remember a similar problem from some compound that was mainly formed as a byproduct of some old Canadian nuclear reactor design. As the tech gets phased out, the material is no longer available in significant quantities, with consequences for a projects that need it (like Iter).
Some things can be cheap if they are produced as a byproduct, but very expensive if they have to be obtained directly.
That rule caught me up too. In regular chess if it is your opponents turn and their only pieces are a king in the 1,8 square and a pawn that is pressed up against one of your pawns and you have rooks in the 2,1 and 8,7 squares that counts as a victory does it not?
No. That is a draw assuming it is the player with only a king’s turn to move.
Translating your notation to normal chess notation:
White king on h1, black rooks on a2 and g8, black king in some random other place, white to move.
That is a draw, because white is NOT in check, but has no legal moves. That scenario is called stalemate. If white were in check, it would be checkmate and a win for black. Set it up on any chess analysis board website and it will say the game is a draw.
Maybe some bot signed up using your email and then did bot things on it. I've had that happen a lot over the years. My Microsoft account is still stuck in German because that's the language the bot used when creating the account (to spam X-Box apparently).
I got a 20y old hotmail/live account deleted by Microsoft because a bot tried to reset my password too many times. Considering the magnitude of the targeted attack, MS found the safest way to keep me secure was to wipe my account. That way the attacker could not get into my account.
I had something similar with a 6-letter apple account that has never been compromised but I guess got put on some kind of list, because I had to go through account recovery almost every time I logged in, which wasn't a big deal until I got an iphone. Apple support was completely useless. Random old buried forum post in a stall marked "beware the leopard" mentioned the behavior and suggested changing the account name.
Nothing in the Apple site or phone stuff would even clue the user in to what was happening, much less how to resolve it.
