Amazon Bedrock supports Claude 3.5, and you can use inference profiles to split it across multiple regions. It's also the same price.

For my use case I use a hybrid of the two, simulating standard rate limits and doing backoff on 529s. It's pretty reliable that way.

Just beware that the European AWS regions have been overloaded for about a month. I had to switch to the American ones.

And, really, wouldn't a car that had controls like a plane be awesome? Probably not everyone's cup of tea, but I'd adore a set of metal physical switches just above the windscreen. Add a HUD while you're at it...

I'm new to cars - I haven't passed my test yet. I also live in the UK, where manuals are the norm (and that's what I'm learning on). What is it that you dislike about CVTs? When you say a real gearbox, is it manual or automatic?

I got an email from Microsoft recently with that funny thin font used for headers. It reminded me that that was a trend around 2016 or so. The headers would have thinner font strokes than the body text, despite being substantially larger.

I remember that around that time (I was quite young) I was putting it in all my attempts at websites (all hideous, even at the time) and I thought it looked really cool. Funny the way trends go.

In the case of the email it was clear that it just hadn't been updated with the times.

BTW we all know this is LLM generated. It's really obvious. Please stop (entirely; don't just get better at hiding it).

It almost makes me want to find some use for them on my Linux box (not that is has an NPU), but I truly can't think of anything. Too small to run a meaningful LLM, and I'd want that in bursts anyway, I hate voice controls (at least with the current tech), and Recall sounds thoroughly useless. Could you do mediocre machine translation on it, perhaps? Local github copilot? An LLM that is purely used to build an abstract index of my notes in the background?

Actually, could they be used to make better AI in games? That'd be neat. A shooter character with some kind of organic tactics, or a Civilisation/Stellaris AI that doesn't suck.

Dark matter (matter that has mass but does not interact in any other way) might be the literal solution. But there are also other suggestions (MOND is a big one).

The https://en.m.wikipedia.org/wiki/Bullet_Cluster is pretty interesting.

My solution to this was to setup my laptop to boot in less than ten seconds. I could generally go from shut down to logged in with Obsidian, Firefox, and Anki open in about 30 seconds.

HS2 is more about NIMBYs and inefficiency than actual technical issues.

I think the prompt should be changed to commit to the joke a bit more. It keeps reminding me that it's ridiculous satire.

Falcon 9 launches every three days. It's not even fully reusable and it burns kerolox, requiring the engine be cleaned.

I doubt they'll have that cadence ready for Starship within NASA's ambitious timeframe, but if they can get orbital refuelling and full reuse working (which are big ifs) high cadence should only be a matter of time. And when you're just refueling it every flight, rather than building a bespoke new rocket (as with SLS), the cost for twelve launches would likely be significantly lower than one SLS launch.

The internal cost for a Falcon 9 is approximately 15 million, and that's including a thrown away second stage, drone ship usage, fairing recovery, and engine refurbishment.

100%. I see them conflated a lot, particularly outside of HN, and I think it really damages the discourse. Censorship for political or brand reasons (and I'm not making a moral judgement by my choice of language) is very different to aligning for safety reasons.

Would we know if they went to space? How long would a geostationary satellite remain?

It's both haunting and brilliant to think about the idea of entire other intelligent species and civilisations having lived on this planet without us ever knowing. Fire and iron and cities and empires and "great people", cultures and religions and stories and families... Civilisations and species rising and falling throughout the eons. It feels a little reminiscent of Sagan's "Pale Blue Dot", but on the scale of time, not space. I wonder if they might have considered this too.

I'm near Bristol. It's still absolutely stunning. It's not just to the north, either - it's everywhere.

It seems the paper made mistakes, using a non-standard model of the CMB that failed upon replication. It's an interesting theory thoughb.

I'm 18. I suspect this is related to attention span: Videos capture your attention far better and are more addictive. Additionally, while people can read, they're worryingly slow and they are so out of practice that the very act of extended reading tires them out - even if the subject itself is trivial. I think my reading speed is slightly above average among adults, and I can read text at my normal speed three times in the time it takes my peers to read it once. That's with brain damage.

These are very intelligent people, it's just that my generation is moving away from reading.

I've had discussions with friends who think academic papers should be replaced with videos. They find writing so time consuming and difficult that they think that an informative, animated video could be made with the same amount of effort as an academic paper. They also say that they're frequently distracted from the content due to the effort of reading itself.

I've been surprised by the extent to which people use "person talks to camera" style videos for revision and re-learning, rather than reading condensed notes. They are significantly slower, you can't scan through until you find something you're unfamiliar with, and they're just plain dull. Despite that, they're one of the most popular ways to revise. Perhaps it's because you can zone out of videos, convincing yourself that you're learning without actively engaging with the content. Again, I don't mean 3b1b style animated lectures, I mean someone essentially paraphrasing the textbook to the camera.

An similar phenomenon that also worries me is the lack of distinction between how people speak and how people write, and not in the "use straightforward language, not purple prose" way. People comma-splice entire paragraphs (if they use paragraphs at all) in a stream of consciousness rather than organising their thoughts.
