Pretty low. Maybe 20 ms higher than normal cellular.

I would be surprised if it is worse than the audio latency in any of the standard video conference software. I expect it would have a ton less processing and less hops.

> if you have a site with regular user engagement.

Ah, gotcha: this is a new Google standard that helps Google sites when browsed using Google Chrome.

Everyone else will discover that keeping the previous version of a library around at build time doesn’t fit into the typical build process and won’t bother with this feature.

Only Facebook and maybe half a dozen similar other orgs will enable this and benefit.

The Internet top-to-bottom is owned by the G in FAANG with FAAN just along for the ride.

Cloudflare and similarly placed CDNs will likely make it enabling it for sites a checkbox like option, e.g., https://blog.cloudflare.com/this-is-brotli-from-origin/ That's where it will have the most savings globally.
uf00lme commented on Which Electric Cars Have Bidirectional Charging (V2L, V2G, V2H)   zecar.com/resources/which... · Posted by u/teleforce

You can buy EV for a few hundreds dollars (bike), cheapest Chinese cars are around $2k, European minis start at 10k EUR.

EVs are actually very cheap as basic city car, but you have to leave out extra features like long range, bidicharging, heating...

Zero emissions means much smaller car, not some monstrosity like 3 tons SUV ls for personal transport.

uf00lme · a year ago
A lot of safety features are mandatory in Eu/Aus/US/NA etc, making imported Chinese cars much more expensive than first thought. Bidirectional charging does not add much cost if planned ahead, since most of the effort is in implementing ISO 15118-20 rather than hardware.

I feel like the main issue with bidirectional adoption currently is the number of groups trying to maximise their profit, everyone wants a cut of the pie: the car companies, energy companies, ev charging companies, ev charging networks, solar/inverter manufactures and government standard groups. The needle won't move until California or other countries with influence force it. In Japan, from a technology perspective CHAdeMO has allowed for EVs to do bidirectional charging for years now.

Side note - I'm all for any extra safety features but I do find that a lot of the software driven features are poorly designed and implemented. I've had bad experiences with automatic braking and lane keeping when freeways driving where I was lucky to avoid having an accidents, so not being able to disable them permanently is a major annoyance to me. It seems like these features have very little real world testing.

I didn't care for the first one either. It was eye candy yet fundamentally hollow imo. I am skeptical this one will be better, but i'll see it in the theater and try to give into the spectacle.

The first Dune had an epic soundscape, it was the first movie I've watched where I thought the audio was doing a better job than the visuals in pulling viewers into the world. I'm going to see if I can pay a bit extra to see it in a cinema this time, and hopefully find one that has a good audio setup.

600% more, 0.60$ for extended support vs 0.10$

Still that might be cheaper if a product is going eol then fixing issues blocking an eks upgrade path. Inversely it’s hard to see any justification for the price increase, I can’t see support for these versions costing 600% more but I guess this is why AWS make so much money…

uf00lme commented on Ask HN: What is a 2024-2030 moat for AI    · Posted by u/jonas_kgomo
uf00lme · 2 years ago
Has a 1-3 team moat ever really existed with new technologies? My best guess would be to somehow get your tech embedded into the defence industry.

My goto moat test: is there an obvious ‘death by Amazon’ route? Amazon can strike fear into entire industries with scale and capital. Very few tech companies could withstand a full frontal assault by Amazon. I can’t see how this trend won’t get worse if AGI occurs during our lifetime.

The only reason there is not more AI or robots doing the majority of the work available to humans, is either it’s cheaper to hire humans or companies just haven’t gotten around to it yet.

uf00lme commented on A battery has replaced Hawaii's last coal plant   canarymedia.com/articles/... · Posted by u/toomuchtodo
jnsaff2 · 2 years ago
The capacity of the battery is 565 MWh.

The cycle life of these kinds of batteries is about 5000. Meaning they get about 5000 charge and discharge cycles before their useful life is over. It could be 2000 it could be 10000 and the definition of useful is also dependent on application.

So in it's lifetime this battery can store 5000 * 565 = 2825000 MWh

The cost of the system was $219M.

About 5% of energy is going lost due to inefficiencies.

$219M / (5000 * 565 * 0.95) = $81.6/MWh = $0.082 / kWh.

I am sorry for calculating the efficiency incorrectly in the original post.

This does not take into account the maintenance cost.

uf00lme · 2 years ago
At least in theory it should be possible to recondition these batteries to make them useful again, I'm not sure who/when/how much but I suspect they will never be completely worthless.

chii · 2 years ago
even a 5k spend on cloud compute is not going out outlast the expected 3-5 yrs of use that a mac M3 would have.
uf00lme · 2 years ago
Not many people use compute 24/7, so if your use cases can be ephemeral than spot/savings plans can be a good saving and using the cloud allows for opex rather than capex controls and taxes

Lovely. Can we have lower bills yet?
uf00lme · 2 years ago
As per other comments, I will likely net profit today from maxing out usage during negative pricing via octopus agile.
