At Square most of the applications run in the datacenters and this project allows AWS Lambda instances to seamlessly call into the datacenters -- basically developers can break out part of their apps and deploy them as Lambdas. This is a de

I don't know if it's true. People tend to conflate the price for cells with those of modules and entire battery packs. IIRC, the holy grail is < $100/kWh for a battery pack.

Batteries are a commodity, so I doubt Tesla would want to reduce themselves to an OEM and shrink their margins. Their energy business might eventually be bigger than their automotive one, but either way I think they will continue selling ve

I think the takeaway here is not that some corners of Go are not performant (and should be swapped for C++/D etc.), but that there are tools in the Go ecosystem that help you figure out what the issue is. Until Twitch hit the bottlenec

You're incorrect, Square has non-SF offices, too. I think @nrp has put it well in his comment https://news.ycombinator.com/item?id=21342101 . Square is categorized differently than Salesforce by SF tax law and pays a di

Agreed, but also we don't know what exactly Apple (and also Google) is collecting - Apple Maps might only have subset of their data. Not to mention, having a good way to build realistic virtual environment for acceptance testing is pro

potential bet on self-driving cars in the future - you'd want higher fidelity maps for those. Also, they can get more accurate navigation for pedestrians etc. Overall, IMHO, this is an investment in user experience.

Very recently there was a flurry of articles about Apple copying popular apps, among them woman health apps [1]. Although they were not wrong to voice their concerns about Apple, it's hard to cheer for the app makers when you later fin

It's so that you can have a seamless module version checksum [1]. The checksum in proxy ensures that you don't "trust on first use" whenever you update a module. [1] https://go.googlesource.com/proposal&#

Yes, we can definitely incentivize people to change their energy usage habits as well. EVs will come very handy if/when their charging schedule can be centrally managed (thru automaker car networks or smart chargers).

Yes, renewable energy like wind and solar are intermittent, so we will need to invest (a lot) more into energy storage. So far storage has been expensive and need to drop a lot, so it can reach mainstream [1]. [1] https://www.pv-

It definitely depends on your use case, so it's hard to tell what's better for you. HAProxy is solid and doesn't take a long time to get started. At the same time, some of the HAProxy 2.0 features have already been available

Tesla Semi has multiple packs that can be charged in parallel. The Megacharger will (likely) be 4 Superchargers combined. 1MW should be enough ;) re: announcement, I'm surprised not much has been said about the flagship cars (S/X)

Looks like they still don't have the "standard interior" option available, so that's extra $5k. Once (or if) they offer standard interior, we're talking $40k. If they're calling this battery option mid-range an

$78k is their most expensive version. The cheapest Model 3 you can get now is RWD + premium interior (no standard interior offered yet) + long range battery = $49k. Tesla still says that base version should come at $35k some time next year.

hardly a model T with ~50-60k cars produced a year. And it hasn't been scaling production fast enough.

by matahwoosh 9y ago
I believe Bolt is capped at 50kW fast charging, whereas superchargers provide 120kW, so not so fast for Bolt ;) (probably at least an hour to fully charge it's 60kWh battery)

Very good point! I was thinking about other potential drawbacks, but this must be the biggest! We're talking about PFS in the next article - https://fly.io/articles/how-ciphersuites-work/
