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…

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 automoti…

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 figur…

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…

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 real…

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 i…

Here's a neat demo in JS https://www.quaxio.com/steering/

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, i…

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.goo…

It's not as bad if you start your company outside of Bay Area or get remote employees.

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 autom…

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…

I just finished this book: https://books.google.com/books/about/Tesla.html?id=5I5c9j8BE... I thought it was really thorough and quite technical, so if you're interested in the earl…

probably 2170, but yeah, small cylindrical batteries

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 HAPr…

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 no…

Android-based.

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 th…
