morepork··on Tesla Q4 2023 Earnings Report [pdf]
Maybe in the US, but if you live in less protectionist markets you'll find Chinese vehicles undercutting Tesla on drive away price.

For example my parents just bought an electric hatchback from GWM for ~27k USD, or ~21k USD after government rebates. Tesla doesn't even come close.

Yeah I don't understand this, they're a massive company now with over 100k employees. Surely they can focus on more than 2-3 projects at a time.
morepork··on Desalination can beat batteries for excess energy
There is certainly a trade off there, does the cheaper electricity compensate for the fact that you need to add say 20% extra capacity and the accompanying costs to your desalination plants as they will now be idle during low renewable production/times of high electricity costs.
morepork··on What will enter the public domain in 2024?
Somewhat tenuous, but Tolkien was taught Old English at Oxford by a New Zealander, Kenneth Sisam[1].

morepork··on Epic vs. Google: Google Loses
Apple didn't need to make as many deals as they're the only OEM. There's no real way to have a separate app store on Apple phones.

Smartphone makers need app store revenue to make the handsets competitively priced. It would really hurt Android market share if all non-Google Android phones were say 10-20% more expensive to compensate for that. Or alternatively if you had a fragmented ecosystem with a separate app store per OEM.

I'm not saying that it's a good thing, but it doesn't seem unreasonable to share app store revenue with the OEM making the device.

Can't speak to the deals with particular app developers like Riot or Spotify

morepork··on Fear of cheap Chinese EVs spurs automaker dash for affordable cars
For years automakers have been pushing people towards bigger and bigger vehicles as they have higher margins, but saying that it's due to consumer preference.

The Chinese automakers are showing that there certainly is demand in those segments if you actually make decent vehicles, and they don't mind operating on slim margins to take market share.

morepork··on Who makes the most reliable new cars?
I think the data is a bit skewed as Lexus/Toyota are the most reliable, and make many hybrid models.

The question should be, for a particular make, are hybrids more reliable than ICEs?

morepork··on Vehicles with higher, more vertical front ends pose greater risk to pedestrians
A station wagon (essentially the same vehicle, but not as tall), or a minivan could do the same, surely? The only thing an SUV is better at than those vehicles is some serious offroading

How often do those charges get used?

For example: https://www.nbclosangeles.com/news/driver-killed-south-la-si...

A driver, allegedly watching youtube, runs over and kills 2 children of 12 and 14 at a crosswalk. But they were only charged with the lesser vehicular manslaughter, not felony vehicular manslaughter.

morepork··on Running Speeds
For sprints in particular, the spikes make a decent difference on the track, more so for elite athletes as they need the extra traction more
morepork··on Running Speeds
A 14 second difference is less than 2% of the total time though, so it doesn't entirely disagree with them. Between dirt in casual running shoes to a track and top tech shoes, there would I guess be about a 15-20% difference, and most of that would be the surface. I would speculate more for a sprint as traction/acceleration is more critical.

If they have the fuel available, may as well be very conservative. Either burn the fuel on descent or have it sit in the tank forever on the lunar surface.
morepork··on Heat your house with a mechanical windmill (2019)
Depends where you live, for us it tends to be more cold and still in winter, but the warmer months are windier
morepork··on Backward Compatibility, Go 1.21, and Go 2
I was pleasantly surprised about 6 months ago when I went to run a game I wrote in Java when I was at university. Nothing huge, but still about 10k lines of code. I originally wrote it in Java 6, and it compiled and ran with no issues on Java 20.

I only used one 3p lib, otherwise just the standard library, which helped, but I was expecting something to be broken given it was over 10 years later.

morepork··on Java 21: What’s New?
Thanks that makes more sense, I had assumed it was for all types as Point used in the example has the same name as a class in the standard library
morepork··on Java 21: What’s New?
There's potential confusion whether the int x from the example comes from point.x (field), point.x() (method) or point.getX() (common getter pattern), just one more gotcha
morepork··on Java 21: What’s New?
It's a bit of an unkind example as most would write the latter as

    if (obj instanceof Point p) {
        System.out.println(p.x()+p.y());
    }
But I can maybe see the value if you need to use x/y more than once.

However in Java it's common to have getX() style accessors, for which this syntax doesn't seem that helpful as your variable would end up being called getX

morepork··on Tell HN: I think I found Toyota's battery
BYD Dolphin is 1285-1450 kg depending on which options you pick, which is in that range
morepork··on Tell HN: I think I found Toyota's battery
Because weight affects range, you could keep the same amount of energy and increase range at the same time as the battery would only weigh 1/3 as much and be maybe 400kg lighter
morepork··on Fitch Downgrades the US Rating to 'AA+'
Nominal debt / nominal GDP should be equivalent to real debt / real GDP, so it shouldn't matter

Looks to me like GDP is growing faster than the debt, at least over the past 2-3 years: https://fred.stlouisfed.org/series/GFDEGDQ188S

That Antarctic sea ice anomaly for this year is worrying
morepork··on Shortening the Let's Encrypt chain of trust
It's a good comparison. I would speculate that it's the target market. If you're buying a Linux laptop you are likely very technical, and know about and want the latest updates. I doubt System76 would get many sales if Pop OS was based on Ubuntu 20.04 and wouldn't get any updates.

However with Android, companies sell 100s of millions of devices to consumers that are more concerned about price point than updates. There just doesn't seem to be the incentive for OEMs to care about it, if the majority of consumers refused to buy devices based on old OS versions or ones that didn't get updates, those devices wouldn't get made.

morepork··on Shortening the Let's Encrypt chain of trust
Fortunately the community doesn't have the perverse incentive of a hardware manufacturer. If updates stop flowing it encourages people to buy new devices.
morepork··on Shortening the Let's Encrypt chain of trust
But Canonical isn't responsible for the Ubuntu forks, it's up to the community to get Kubuntu, Mint, etc. updates out
morepork··on Shortening the Let's Encrypt chain of trust
But Microsoft doesn't make Windows open source and allow customers to fork the OS.
morepork··on Shortening the Let's Encrypt chain of trust
6.1%, those using 7.0 and older will be affected. But that number will have fallen a bit by the time the certs actually expire in a year.

There's also the possibility that Chrome decides to bundle this CA like Firefox mobile does, which would mean the majority of users won't have a problem. From 5.0 the builtin webview is updatable too - I think it uses Chrome's engine.

That leaves other browser's such as Samsung's one which probably has the most usage, no idea if they bundle root CAs or not.

morepork··on Heat Pumps – The Well-Tempered Future of A/Cs
In a technical sense yes, outside of niche systems such as evaporative coolers.

Also all refrigerators contain a heat pump.

More than railways, imagine if roads were privatised and you had 2-3 roading networks trying to get to as many homes/business/etc. as possible
