Data center mech eng here - from our perspective it's higher rack densities typically due to GPUs. It's certainly possible to have high densities due to CPUs as well but I've seen a significant spike in rack densities in the last couple of years which has caused a switch from air cooling to liquid to chip.
One side effect of higher density is less footprint on the building to exhaust the heat, which is one reason (the main one being efficiency) that cooling towers and indirect evaporative cooling are favoured over air cooled condensers which leads to large amounts of water consumption.
Cooling towers are also much quieter than air cooled condensers which is a significant factor near any residential areas. It would be great to see more use of data center waste heat for process or district heating to save on water consumption.
Another issue with AI training in particular is huge (multi-MW) swings in power consumption at the start and end of each training run which must be a nightmare for the sparkies.
That's a reasonable take - Apple had a gun to their head regarding tarriffs and exposure to China, but I'd still love to know how Steve would have played the same hand.
The issue is maximum take off weight. Presumably the discharged battery weight would be the one you use in the pre-flight MTOW calculations, because the worse case scenario is one where you're landing an almost discharged battery and have to go around.
Looking forward to seeing solid state batteries for aviation, but the scary part is that they get heavier when they discharge as oxygen from the air turns into solid oxide.
I suspect this unawareness of language use is universal. When I lived in the UK in the early 90's, people would discuss the weather in celcius when it was cold and fahrenheit when it was warm with seemingly no idea that they'd switched.
Easy transfers between different people's iThings with Airdrop. I got my CompSci degree over 30 years ago and yet my 74yo aunt taught me this - the shame!
Apologies for a trivial question. I have an odd fascination about the edge cases of birthright citizenship.
If a non- citizen gave birth in an American embassy, would their child be entitled to US citizenship? What about US Antarctic Territory or aboard a boat within US coastal waters?
Congratulations YC! I remember prior to HN, pg used to post his essays to Slashdot under the username Bugbear and all the attendant sniping and lame memes that would come back in response. Hacker News was a breath of fresh air and continues to be my favourite online community.
They like to showcase the visualisation and AI stuff but there's also a lot of development doing stuff like parametric modelling plus everyday CRUD apps for internal systems etc.
Fair point. I did my mech eng degree in Australia where university is heavily subsidised for citizens. Total cost for the 4 year degree here was $32,000 (roughly $21,560USD at today’s exchange rate)
