> The battery has a life of ~120k miles … This appears to be untrue. High-mileage Teslas are showing about 10% range degradation after ~250kms on the odometer: https://electrek.co/2020/06/06/tesla-battery-d

You're making a stock-vs-flows comparison: a battery is manufactured ~once for the lifetime of a car and then produces ~zero emissions per marginal mile driven. Combustion engines produce emissions for every mile driven (and require so

IIRC, the average price of a car last year in the US was around $41k. There are many options whose MSRP is under that price, e.g. https://www.myev.com/research/buyers-sellers-advice/comparin...

IMO it depends on what part of the ruby feel you most enjoy. Sorbet makes it harder to work with the runtime-magic parts of Ruby (and in some cases we rely on tooling-generated code instead of runtime dynamic stuff), but it doesn’t affect t

(Disclaimer: I work at Stripe and use Sorbet) IMO the Sorbet additions do impact readability, but it dramatically improves understandability. In a codebase past a certain size/number of contributors, you're always going to have am

I can't speak to your office environment, but in all the offices I've worked in, I haven't been "forced" to interact with coworkers more than I want to. Being at the office gives me the option to engage in high-band

My personal answer to the titular question is something like "there's only so much you can do with our predominant programming paradigm (i.e. plain-text)". Programming languages specifically can only make incremental improvem

Aesthetics matter to some people. I would be a little more sad if I had to plug in a chunky CCS charger rather than the relatively-small charger Teslas have now. (To be clear, standardizing on CCS is likely a good thing and I'd support

IMO browsing to the location first, and then creating the thing in that spot, is fuzzy search. The equivalent to "plonking a shovel" would be knowing exactly where a file should go in the hierarchy and touching/creating it

Is the "nested filing cabinet idea" just referring to the file system and explorer? Or are there other aspects to that idea as well?

by feifan 5y ago
"Create a thing here " is a really powerful interaction. You often start the process of creation by navigating near the relevant bit (path in the file system, module in the codebase, etc), and then realize that you need a new fil

To me, someone whose gaming experience rounds down to "never", but who's casually interested in maybe playing some games, this looks very appealing. Switch form-factor but it runs PC games? I don't need to carry around a

I'm early in the tinkering/prototyping phase of a developer tool (not a text editor) that is native AppKit, and it'll stay that way if/when I release it. I actually find myself a lot more productive (i.e. can build a g

This line of thinking very likely has the causation backwards — Tesla is a complex-enough business that they can determine how much they're gonna make in regulatory credits, and then turn opex up or down accordingly, with profit being

If you also have a direct line to your users, you could try asking them how much they'd be willing to pay for either some new feature that's about to come out, or for the right to early-access. Get maybe 3–5 data points and you sh

Deliveries are their most-watched top-line metric, and it's likely they can't delay deliveries anymore without significantly impacting their quarter.

The tone map "flickers" on/off unpredictably and in a non-undoable way (when it's off it appears to just be a flat plain RAW). If I actually try editing a ProRAW file, the whole photo area gets covered in green or red re

IME paying for rent and some utilities via cards (including debit) come with 3–5% additional fees — are you passing those costs directly to users?

For me, Halide lets me shoot regular RAWs, whereas the stock camera doesn't — I don't like working with ProRAW because it renders buggily in Photos and Lightroom and I don't find it worth the file size.

For my mom, her iPad (Mini) is her only computer, including for taking photos. She much prefers the large screen (vs a phone or camera-sized screen) and wouldn't know how to transfer photos over from a traditional camera. I imagine my

It does appear people are willing to pay those costs :) Also, electricity transmission appears to be much more expensive than generation. On my PG&E bills in California, delivery costs 2.5x as much per kWh as generation for 100% renewab

I'd imagine sensor fusion in this context isn't a singular problem right? It seems entirely plausible that for Tesla's system , it's straightforward to integrate cameras where the resolution is known and data is homogen

Same reason you have heating units in your house/building rather than at a municipal heating plant … people want to buy self-sufficiency for their house/building, and it's easier than scoping/building large-scale project

I'm not entirely convinced it's a good idea, but one convincing argument I've seen is that sensor fusion is hard and it's not a priori clear which sensor to believe when they provide conflicting information. It's en

I imagine most people on HN would take the latter, but most people in the broader population aren't that bothered by ads, and most people would probably put up with ads rather than pay e.g. an extra $50 (especially if it's a side-

I imagine for many (most?) people, it's not that they want the "internet connected garbage"; it's that they want the big 4k TV and they're wiling to put up with the garbage that comes with it.

Done — I think antialiasing looks better on Retina screens in dark mode so I kept it only for that case (removed it for non-dark mode or non-Retina).
