- I'm not sure there are many countries that actually have free childcare and free buses. Talk about it, yes. Subsidized to a degree, yes. But pretty much every municipal transport is already heavily subsidized.
- It's... a bad article?
It takes as given that the tech is here, and it's economically feasible, but it's not giving any arguments. Just blames the people.
It's also not exactly defining the problem space. Is it talking about air-air AC with heating? Those are common and very cheap. Is it talking about large HVAC systems that include hot water? Those are indeed a hellof a lot more expensive, but also a hellof a lot more complex. And no matter what the author is saying, technology isn't to the point of giving us hot water from heat pumps. The math just isn't mathing - to take cold water and heat it up to "hot" by cooling off freezing air, you'd simply have to cool huge amounts of air. Yeah, probably, if you put a room-sized HVAC system and spend a ton on electricity - but that's where it stops being competitive.
Is it talking about geothermal heat exchangers? Because those are indeed a lot more efficient - but also more expensive for obvious reasons. You need to drill.
- Yeah, happened to me too. Brief but intense. Strangely, only the first time.
When I got out I told the technician (I though I had a panic attack, and was puzzled that it happened at the end of the session), and she said "oh, it was probably the contrast, happens rarely". Apparently rarely enough that they don't warn the patients. To be fair it was harmless, and they'd have many more cases of nocebo nausea than actual nausea.
- So that's an European thing? huh. We have this in Romania - a couple years back when the war in Ukraine started just as the green deal took effect, the gov started spending like crazy on subsidizing energy. But they did it in a convoluted way with a layer of intermediaries that basically were allowed to invoice the state for price differences from arbitrary price levels. Almost "I'd like to sell at twice the price but you're not letting me, so gimme the difference" - if not exactly that.
I'm not sure if I'm feeling better or worse that it's a EU invention. Either way, it's hellof a corrupt practice.
- Considering AI-pornbots are increasing the derivate of the function, they might actually be the right move.
- I'm not sure what your "obviously correct choice" here is, given the musk hate, but to me:
Option one basically lights a huge pile of money on fire, for a vanity goal.
Option two uses a much smaller pile of money to do something useful long term.
- I wonder:
- what's the actual oxygen carrying capacity? If they're up to human trials then I imagine they've already validated this step in animals
- can it also scrub CO2?
Without doing more research, I'm putting most of the probability mass into it being be a small but significant oxygenation aid. Not enough to let us survive without working lungs, but enough to push the odds in emergency situations, while also being harmless. Something like 5% extra survivability for a $100 cost and a sore butt. Well worth it, but not a revolution.
- That's an ECMO machine, and it works. It's also cumbersome and expensive. This kind of thing might easily become a standard resuscitation step in first responders.
- Yep, he was wrong about that one. He was also 20 something, I think.
- Comment was "of late".
If you want to look long term, well, they're still stellar :) Considering everything they're achieving, and how they're so much better than everybody else in the field.
It's a failure only if you look at a rather small time range and criteria. Which I don't think was a surprise for anybody - Elon is famous for going for moon shots and failing, but still delivering better than anybody else.
- The security implication here was writing a blog post. You're allowed to use a cheap box cutter even if you work at NASA, as long as you use it to open mail. That's what satisficing means.
- I do, which is why I specifically said:
> outside maybe PR and politics
It's still a bad idea, objectively.
- Except it kinda was stellar? When the test pad blew up I was absolutely sure we won't be seeing a V3 this year, but they recovered amazingly, with the last V2 test checking pretty much every goal they set for it.
- I'm not really sure if keeping a strict schedule has any real relevance here, outside maybe PR and politics. Starships will drop the cost to other bodies in the same way Falcon dropped the cost to orbit. Why would anyone want to invest in a technology and a project that will be obsolete by the time it's implemented?
- To most of the replies to my comment, the point is that:
- ChatGPT is _satisficing_, not optimal. It's definitely worse than a dedicated decoder tool.
- and it's also much more versatile, so it will be satisficing a large array of tasks.
So in scenarios where precision isn't critical and the stakes are mid, it'll simply become the default tool.
Like googling something instead of checking out wikipedia. Or checking out wikipedia instead of using those mythical primary sources. etc.
- "Why use a calculator all the time? Just use pen and paper!"
ChatGPT is the right tool here, because it does the job, and it's more versatile. And underneath the hood it most likely called a decoder anyways.
- Weeks. I'm talking about multiple business weeks to spin up a new server. Sure, in a pinch I can do it in a weekend, but adding up all the stakeholders, talking it over and doing things right it takes weeks. It's a normal timespan for a significant chunk of extra power - a modern day server from Hetzner comes with over 1Tb of RAM and around 100 cores. This is also where all the reserve capacity comes from - you actually do have this kind of time to prepare.
Sure, there are scenarios where you need capacity faster and it's not your fault. Can't think of any offhand, but I imagine there are. It's perfectly fine for them to use cloud.
- > What is old is new again.
Over the years I tried occasionally to look into cloud, but it never made sense. A lot of complexity and significantly higher cost, for very low performance and a promise of "scalability". You virtually never need scalability so fast that you don't have time to add another server - and at baremetal costs, you're usually about a year ahead of the curve anyways.
- You don't "build" such a system. You change the metering to follow supply, and everything else will follow naturally.
You'll have enthusiasts that'll do homebrew systems to take advantage of the economy, then you'll have companies catering to their (tbh, hobby), then you'll have products that are actually useful, then you'll see mass adoption. Like in everything else.
Trying to plan a huge strategy from the onset feels (and is!) daunting. Just make sure the price fits the reality, and savings will follow naturally.
And I'm pretty sure she did it just for laughs. I also built a listening device to hear what my mom was saying when I wasn't there. But it was too boring to me to actually listen to the conversations, I don't think I ever actually did it. But I did enjoy immensely setting it up.
