• ⁨Comment⁩ on ⁨SpaceX is worth less than half of its $1.75 trillion IPO target, Morningstar says⁩ ⁨⁨1⁩ ⁨day⁩ ago⁩:

  They’re only going public with 5% of the shares to constrain supply and push up price and thus net evaluation. They’re also probably going to have to get rid of Xai as it is a dead weight on the company as a whole.

  It’s going to be very messy and if people want anything to do with it, probably best to wait a bit longer and buy when it’s dropped substantially in value.

• ⁨Comment⁩ on ⁨The Dead Economy Theory⁩ ⁨⁨5⁩ ⁨days⁩ ago⁩:

  at a certain point all you can do is laugh. Like, there is so much being left on the table, so many legitimately useful applications, but they only seem to care about chat bots and robots, because their conception of useful and powerful isn’t a better product, but how they can substitute capital expenditure for labor.

  Managing people is hard, developing new products is hard, implementing new technology is hard. Selling vapor wear to other business? Easy. Taking in a bunch of investment on outlandish promises and then selling the company before you have to deliver? Easy. Making usage numbers go up by forcing something infront of users? Easy.

• ⁨Comment⁩ on ⁨Utah tells porn sites to take the P out of VPNs, and it's their fault that they can't⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:

  I think in the case of Utah it’s something beyond just wanting to spy on people. I think the LDS(Mormon) church legitimately wants to stamp out porn all together among it’s members. The first step to that is of course, getting a comprehensive list of everyone viewing porn, via ID collection. Then hand that list over to the LDS church, who can name and shame members they find on it.

  Now, they probably will not be able do this everywhere, but, in Utah, it is absolutely with in their power given how much power it has over the state government.

  Or, 40% of users give up after being stonewalled by a bot.

• ⁨Comment⁩ on ⁨Science is iterative⁩ ⁨⁨4⁩ ⁨weeks⁩ ago⁩:

  Thermo dynamics, in short.

  In long, because adding some heat recovery system to the engine block would mean decreasing the cooling efficiency of that block, thus making the block hotter, and decreasing the efficiency of the engine. Since the engine makes power based on the differential of heat/pressure from the top of the stroke and the bottom of the stroke. If you make the system hotter, then less energy can be extracted per unit of heat produced from burning fuel. Any energy generation from the waste heat of the block would be offset by efficiency losses in the engine it’s self.

  Now, most engines don’t actually extract all the energy they could from that differential, which is why turbo chargers are a thing. They use excess heat in the gas exhausted out of the block, expand it to ambient pressure and temperature over a turbine, that turbine then runs a compressor, and that compressor raises the pressure at the air intake. More air entering the engine in the same volume allows for more fuel, thus increasing the energy density of the charge, increasing the differential in heat between the top and bottom stroke, increasing power and/or efficiency depending on it’s tuning. But that’s not utilizing heat from the engine block, but heat in the exhaust.

• ⁨Comment⁩ on ⁨Why Reddit blocked my daily visit to its mobile website⁩ ⁨⁨4⁩ ⁨weeks⁩ ago⁩:

  It’s not just Reddit, so many companies try and shunt you off a mobile web page and on to their app, despite many apps being little more than a pre loaded mobile web pages.

  Why? Because users can modify how they interact with a web page, they can install extensions that modify how the code from the website is run, or just deny web pages access to some other process. There is very little a company can do about that, they have no control on how the user chooses to run the page. But… with an app, users can’t modify how the program is run. No plug ins, no web extensions, no choosing not to run some part of it, just the software as distributed by the company. Meaning full fat ads and complete access to any information the OS will let them have, way easier to make money on users that way.

  Technically, it’s possible to alter any program, but it’s very hard if don’t have the source code, and it’s illegal to do so in many cases thanks to section 1201 of the DMCA, especially if you try and distribute that modification or tell others how to do it.

• ⁨Comment⁩ on ⁨Magnolias⁩ ⁨⁨4⁩ ⁨weeks⁩ ago⁩:

  Ginkos are crazy because like, they were the last branch of a dead tree of life, secluded deep in mountain range in central China, likely to go extinct next time there was a significant climatic shift in the area.

  And then humans were like “damn, I like this tree, I will plant it literally all over the world” and in all likelihood this just massively improved their chances of surviving a few more million years, since now they’re not liable to get one shot by a single event in the area they’re native to.

• ⁨Comment⁩ on ⁨Major L⁩ ⁨⁨5⁩ ⁨weeks⁩ ago⁩:

  In the us, there was a dark and dismal corner of poltical science called Kremlinology, where far to much attention was payed to the positions various people were during speeches and parades, trying to determine who was and was not influential with in party at any given time, and then try to determine Soviet policy and action based on this.

  Having access to the archives, we now know that they were almost entirely wrong, and the times when they were right were basically just random chance.

  Like, it was ancient divination more than it was real analysis. People called them out on it at the time, but, they were influential because the CIA was gullible and congress was desperate for any sort of insight.

• ⁨Comment⁩ on ⁨Google says 75% of the company's new code is AI-generated⁩ ⁨⁨5⁩ ⁨weeks⁩ ago⁩:

  *75% of code was written by people who were required to have an AI plug in installed.

  Probably also having their usage ranked.

  Also have had their work loads increased and their deadlines shortened.

  And if they don’t hit the metrics and meet the shorter deadlines… they get fired.

  I’m sure that’s a recipe for functional, well tested, efficient, and secure software. Definitely not creating a shit ton of technical debt.

• ⁨Comment⁩ on ⁨Land where⁩ ⁨⁨1⁩ ⁨month⁩ ago⁩:

  The nasa blog on the final day said. “At 5,400 feet, Orion’s drogue parachutes were cut and the three main parachutes deployed, reducing velocity to less than 200 feet per second and guiding Orion on its final descent and splashdown.”

  Which is to say “less than” roughly 60 meters per second. Somewhere else on the site I couldn’t find again they mentioned it being a touch down speed of 20 miles per hour, which is a fair bit slower at about 9 meters a second, but that’s still a car crash if you’re hitting a solid surface.

  The point remains. Getting a large object like that down to a soft, non injurious, speed is not practical with just a parachute. Other techniques must be employed.

• ⁨Comment⁩ on ⁨Land where⁩ ⁨⁨1⁩ ⁨month⁩ ago⁩:

  So, the issue does come down to the chutes. A chute capable of reducing decent speed to 10m/s is significantly larger than one capable of getting the speed to 60 m/s. Impractically large on a weight constrained thing like a space capsule.

  The Soyuz uses a small set of retro rockets to reduce speed in the last few seconds before touch down, and even then it’s like being in a car crash.

  On the Vostok capsules the astronauts didn’t even land with the capsules, they just bailed out and parachuted down.

  Landing in the ocean is significantly more comfortable and less complicated.

• ⁨Comment⁩ on ⁨Space Honey⁩ ⁨⁨1⁩ ⁨month⁩ ago⁩:

  This was legitimately a significant concern that early space programs had. Like, how well would people be able to swallow in free fall, would certain kinds of food cause problems? The food experiments during the Gemini program are pretty interesting

  So spraying Windows with the assistant, regardless of how users felt about it, was somehow an accident?

  Probably more that internal politics at the company lead a bunch of project leads to try implementing it. If leadership keeps emphasizing how important AI is, and people who have “done stuff with AI” keep getting promoted, then of course people are going to shove it anywhere they can, and of course the higher ups will approve it. It’s classic group/cult think in a hierarchical system.

• ⁨Comment⁩ on ⁨‘The era of invincibility is over’: the week big tech was brought to heel⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  Don’t let this become a “protect the kids” thing. The intentionally addictive and manipulative design of these platforms has been just as harmful to people across a wide spectrum of ages. The solution is not to ban kids from using these platforms, the solution is to hold these platforms accountable for their behavior and put regulations in to ban intentionally manipulative design. Adults are just as much victims of having their brains cooked by this shit, and it’s had larger scale societal consequences that we need to take seriously.

• ⁨Comment⁩ on ⁨That's how the world works.⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  Probably not, ammonia production isn’t exactly a huge portion of natural gas usage, it’ll just have to compete on price with other demands, other things with lower value will get priced out of the market long before nitrogen fertilizer. The price for it will probably go up, already has on futures markets, but not by a huge amount, not even the biggest blip in the past decade. And nitrogen fertilizer is a fairly small portion of overall costs for most agriculture, so it won’t be a significant increase in price.

  The places it might have an impact are on products with really narrow profit margins already, like commodity corn in the US (actually a lot of commodity corn breaks even or even is grown at a slight loss because reasons ) and a lot of that goes in to non-food uses like ethanol(for gas), chemical production, or even for use in construction materials.

  Ether the user who put the bot in a position to do something illegal is liable, or the person who made the bot that did something illegal is liable. But 90% of the reason hegseth want to use the bots is to avoid liability when doing illegal stuff, and if anthropic is saying “hey it’s not our fault if you break the law using our product, we told you not to use it like that” then they’re basically denying the main use case for hegseth, who really really wants a get out of jail free card for breaking the law.

• ⁨Comment⁩ on ⁨Block ditches 4,000 staff, because AI can do their jobs⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  Any job that can be done by an LLM wasn’t a job that needed to get done In the first place.

  any manager who tries to replace an actually useful job with an LLM is going to get bit in the ass as productivity slows to a crawl. Other people will hav to step in to clean up the mess and basically do the work that should have been done by the person replaced. Most of the jobs being “replaced by AI” are actually just routine layoffs or companies correcting from over hiring.

  I’ve read a story the other day from someone who said they left Amazon due to what a mess it was becoming internally. How increasingly managers were hiring people they didn’t need so their team would be bigger and they would seem more important. This is a well known phenomenon. I suspect a lot of people who did this and created a mess are using the excuse of “embracing AI” to give them selves an off ramp from the mess they created by bloating their departments.

  On the one hand, I’m skeptical of the assertions that pen and paper is inherently a better way to take notes and learn.

  But I do agree with the general aversion to a lot of ed tech. So much effort to shove kids faces in front of softwear and hardware that was sold to administrators by marketing teams from big tech companies. So many opportunities for those tech companies to exploit local school districts, ether to extract unreasonable profits, or for access to a mailable locked in user base.

  If a school is going to go all in teaching with computers, they need to be carefully choosing what they use and not just adopting a premade package from some tech company.

• ⁨Comment⁩ on ⁨The world’s oldest known vertebrates had two pairs of eyes⁩ ⁨⁨3⁩ ⁨months⁩ ago⁩:

  It seems likely that its external sensing function faded before the development of “hot blood” (endothermy) as it’s vestigial even in very basal reptiles like the tuatara, so likely it was already disappearing as a sensory organ fairly early in quadruped evolution. Snakes, crocodiles and turtles (all exothermic) all lost it completely as an external feature, snakes are particularly notable as they’re in the same branch as tuataras and lizards, many of whole still have it as a vestigial external structure. It also appeared in some extinct branches of therapsids(many appear to have been endothermic) in some form, but is completely absent in mammals, the only surviving branch of therapsids.

  It does function as a sensing organ in many amphibians, suggesting that it became vestigial for sensing some where in the early evolution of amniotes, but stuck around as an external structure across multiple branches but many have since convergently evolved to loose it as an external structure.
