> "They are a battery company."

Not really. Tesla, like most automakers, purchases most of its battery cells from other companies (Panasonic, CATL, LG Chem). In recent years they have started to manufacture their own cells as well, with their 4680 cell manufacturing line at "Giga Texas". But this is a small portion of the cells they use globally.


That's interesting cause FY2025 had them do about 14 billion in battery/energy products (revenue). With auto being a little over 60 billion. The energy products seem to be growing in volume though

Yes, "Energy Products" refers to Tesla's energy storage products (home Powerwalls and industrial-scale "Megapacks"). Tesla manufactures these packs using battery cells they buy from 3rd parties. Tesla's value is added in the pack design, software, inverter electronics, branding, etc.

Didn't tesla got a bunch of US government money to install superchargers everywhere? Wouldn't that be under 'energy product'?

> "Edit: Tesla is 3 times Toyota in valuation, not 5 as I said earlier, not that it changes the argument much."

Per Google finance, Tesla's market cap today is $1.42T. Toyota's is ¥48.72T, or $307B USD. So that would make Tesla's valuation about 4.6 times Toyota's.


Of course thank you, Idk how my brain farted when I did the double check…

Sure and Toyota [1] has significantly more outstanding bonds than Tesla [2] which should depress it's market cap.

Hacker News itself is a prime example of a website that doesn’t support dark mode, but could do so trivially (and, IMO, would look so much better if it did!)

My HN is in dark mode, though the honors for that accomplishment go to the duckduck browser. Been reading HN on dark mode a while now (light mode burns me eyes, only way to use HN for me now is with the Duck)

P.S. the Duck browser literally has a universal dark mode setting, I don't recall a site it wasn't able to dark-force darkify for me (language is fun)


That browser, just like all Chromium based browsers, get that setting for free from Chromium making that a thing in the first place. Some browsers choose to bring up that option in settings, but it's still just the same thing as the #enable-force-dark flag. (What's really unfortunate is that Firefox doesn't have anything to match that feature, and all of those "auto dark theme" addons are just awful, they're less reliable and look worse.)

There is no downside to having prefers-color-scheme media query set up, even for HN. Too bad still roughly 1 in 4 popular websites support it.

no, choosing light/dark mode should be manual

Per website...? Why would anyone want that instead of just using the system-wide preference? Many sites/apps have an option of system/light/dark.

For me, most dark mode styles are awful (jet black background bright white text). I'd rather have per website toggle so I can apply my own styling when the site's styles suck.

But you can have both? Automatically switching between light and dark mode based on system preferences is handled by CSS, which you can override with your own styling.

I have found it incredibly hard to override dark styling, at most you're modifying/merging styles. Dark reader extensions don't work well turning a dark site light, and I've had limited success injecting styles with tampermonkey/stylus. Of course it can be done, just override every style set by the site. But this involves setting a lot of styles and must be done case-by-case rather than using an auto styler. The only thing that works reliably in an automated way is starting with a light style and then modifying it to dark styling.

I also detest the conflation of OS dark preference, browser chrome theme preference, and website rendering preference. It should be obvious to anyone that these are three different concepts where people can have different preferences for each. The cargo-culting in silicon valley drives me nuts.


> But this involves setting a lot of styles and must be done case-by-case rather than using an auto styler.

If the website is using modern CSS then the colors would be set via CSS variables instead of being set inline in lots of places.

> I also detest the conflation of OS dark preference, browser chrome theme preference, and website rendering preference. It should be obvious to anyone that these are three different concepts where people can have different preferences for each.

Most people definitely prefer consistency so I don't think it is unreasonable to default to following the system preference.


I don't mind the default, but it's the lack of customization in most apps that is a severe oversight. I can't change my theme in the OS without it telling apps I want a dark theme (I don't). I can't change the theme in the browser with it telling every website I want a dark theme (I don't). There are no overrides to force the website rendering theme to be decoupled from the browser/OS theme. In everyone's mad dash to implement a dark theme, no one stopped to think for half a second. It's asinine.

Hard disagree here. Follow my system default.

There should always be three options. System (default), Light, Dark.

Iam a both kind of guy.

No, it should follow system defaults with an option for a manual override. People like you are the reason the internet is broken.

there are a lot of design choices which Hacker News does not support ;)

Not sure if you would like my dark mode modifications to HN, but here are my CSS[1] and JS[2] modifications.

Javascript: https://pastebin.com/50EUfktL CSS: https://pastebin.com/nzEhxxBY


My Hacker News extension [1] re-applies the colours from HN's news.css (including the mistakes in it ^_^) using CSS variables [2] to make it themeable, and adds a default dark mode with an OLED variant, and a way to apply your own theme CSS.

Personally I'm using an HN version of Twitter's Dim theme [3]

The only chrome extension I have is to make hackernews support dark mode. Love having it

I do appreciate how minimalist hackernews tries to be, but I think respecting the operating system's theme can be considered very minimalist


This feature works well on Hacker News, just trying it on the beta.

I use Stylus to apply a dark theme to HN, and much prefer it. https://i.imgur.com/USbXXEK.png

People should stop using Imgur. 99% of the time when I click an Imgur link, I get a 403 Imgur is temporarily over capacity. Please try again later. I highly doubt that they are, and they are just blocking VPNs.

If you've got a better suggestion, I'm open to it. I generally just want a throwaway place to host an image publicly for a specific purpose.

Buy a domain and server, rack up the server in a nearby datacenter, and host on that. Easy.

If you go with a cheap enough colo provider, you can get it down to like $200/mo (depending on electricity prices and such where you are) with an initial cost of like $800 for some used server hardware.


Dark mode and some small improvements for mobile usage would be amazing and don't seem at all hard. It's pretty amazing HN hasn't implemented them.

HN works just fine on mobile. I am posting from a GrapheneOS phone. If it ain't broke, don't fix it.

I disagree. It's pretty terrible. I use hackerweb.app on mobile and it's much better however it doesn't support posting. Thus I have to torment myself with the regular website to post a comment such as this.

I misclicked "hide" on quite a few articles when I meant to read the comments

If anyone here is open to using the Stylus extension, I've re-shared a dark theme for Hacker News recently and it's been lovely. [0]

I hate that folks recommend random extensions. Browsers should include style/css editors (with the ability to save and reload styles later) for accessibility. Since we don't have that, uBlock Origin does a lot of heavy lifting, and can add a dark mode to HN and other sites.

I'd share my ruleset, however, I am missing one. Before I switched PCs (motherboard caught fire) I had one that made everything dark mode, didn't dim the text, and buttons/text inputs/other inputs were also properly inverted. I had to make it myself because googling Hacker News dark mode always led to the same broken themes. I forgot to back it up. Adding dark mode doesn't need a bunch of extensions, and while I'm sure the "stylus" extension is probably useful (I haven't used it, sounds like a CSS override extension), UBO does CSS and JS.

Just my thoughts. Don't mind me.


Indeed, I just figured I'd share the full setup. IIRC, Stylus was derived from "Stylish", which was a hugely popular CSS override extension that became spyware around 2016 and was taken down in 2018, and now Stylus (and others of course) fill the gap. It would be very nice to have this integrated into the browser, I agree.

Opera had this in 2003, but sadly none of the major browsers copied it.

I still miss Omniweb, a browser with user defined stylesheets, per site settings, and workspaces… so many good things. Free browsers killed it off.

And vertical tabs, only two decades before Safari did.

Safari and Firefox both support loading user styles from disk.

The latest Safari also supports creating limited extensions on the fly via AI.


No thanks. When you are my age you will understand.

I have no idea why all the fucking vibed websites that swank around the web these days are unable to do a simple thing:

  * Have one or more "themes" with dark and light variants
  * Query the browser for a preference of light or dark and offer the default theme with the probed variant.
There is also the rather wider issue of accessibility in general. I happen to be an older bloke with astigmatism and rapidly worsening ... fucked up focussing and glasses and that. I'm lucky to have both eyes and decent colour perception and general all around acuity (for a given value of acuity).

It's 2026 FFS. Why on earth is this even being discussed as an issue? We have all these cool vibed efforts that can't even be bothered with simple basics.


They’re now formally interested in doing one but, I imagine, not very urgently relative to flag reasons and other stuff.

I use a chrome plugin precisely for this and I can confirm - my eyes hurt less

https://hcker.news was originally made so i didnt solar flash my kid in bed while they were sleeping

it now has many dark themes, bloomberg is my favorite.


It's great!

Where are the themes? (I might be missing on mobile)


my bad, upper right corner half moon icon!

Gotcha I was looking for a Bloomberg terminal like theme, whoops

Whoops is on me, I misunderstood your question. That theme is there, you have to long press the theme button. Just realized how unintuitive it is, gonna move it to the settings.

I got neurological lyme disease a few years ago. Anything with a white background was like a VGA cable being half plugged in.

The fact that this website wasn’t capable of dark mode made me create a CSS overlay on desktop.

I am back to somewhat normal now with my eyes, but I feel really bad for anyone in the same position.

I know that the current exact HN is magic, but come on. There is CSS to detect the system’s theme. There is no need to create a button or anything.


Please no. Dark mode is extremely difficult to read for me.

Are you supposing they would they force it on for you? Or does your dislike of it mean nobody else should have the option?

This is, in fact, what drives a lot of politics. "I don't like X therefore nobody may have X."


That’s why it’s a mode :-)

I'd prefer dark mode because then I notice my eye floaters much less when reading.

Ironically this comment is now almost impossible to read.

They were at this long before crypto. Look up "Bangladesh Bank robbery", for example, where NK hackers attempted to steal almost $1 billion from the Bangladesh central bank in 2016 (and were partially successful).

Pretty wild that even the PS5 still has a blu-ray player and that PS5 games still come on optical discs. No doubt this adds significantly to the costs of both the PS5 hardware and to the costs of game distribution.

I have a feeling the PS6 won’t have an optical drive…


Don't need to guess, they literally told us there will be no more physical media, ever.


Sony has already announced the end of physical games for the PS5. If the PS6 will have an optical drive, it'll be an add-on and only for backwards compatibility purposes. Any kind of a PS6 optical drive will definitely not add significantly to its retail price though.


The PS5 optical drive is still incapable of handling Dolby Vision, which is a massive shame.


I think it's just that Sony doesn't want to pay to license Dolby Vision, not any actual technical reason.


and the disks are only used for entitlements, not for the game. when you stick the disk in, the game is downloaded.


Why is this downvoted it’s exactly how it works, you can see in the UI that the game is downloaded when you insert a disk, and you can’t play until the download completes.


If the PS5 is offline it will install the game from disc. If it's online it will auto-download patches (which may be the entire game).


When you insert a disk, the game gets COPIED to the hard drive, not downloaded. Some games need additional downloads or patches that they will download, but that's up to the editors. Nothing is preventing them from releasing a finished game that fits on a disc (with some exceptions for some huge AAA games that won't fit, of course)



How do you get to this URL without iOS wanting to open/download Apple Music? I don’t even have Apple Music installed…


Long click and choose open


long press the link


If I had to pick one tune to listen to every day, that wouldn’t be the worst one.


If there's anything I've learned from using my favorite tracks as a daily alarm: there is no music that I won't eventually start to hate :(

It's gotten to the point after 15 years that I've stopped trying, for fear of ruining even more good music.

I have noticed too that some people are more/less prone to this, which makes me wonder: is anyone completely immune? Are there people who, no matter how often they hear a song, will still love it?


... and the updates that come through the beta channel aren't clearly labelled as "beta" or "release candidate".


I've always found that quite strange. Clearly the information is present because they're not signed with the same keys.


Maybe it could be sold as a safety feature.

Suppose you accidentally drive your car off a cliff. Accelerometers and other sensors (cameras) could detect the fall and activate the cold gas thrusters to rotate the car into a safe orientation and bring it to a soft landing.

It should even be possible to use the thrusters as an emergency braking system in case of loss of traction, rollovers, departing the roadway, etc, to avoid or reduce impact damage and injuries.


In theory it could be a car that avoids nearly every accident. Say you're at a red light behind a semi truck and an SUV is about to rear end you. The car could detect the impending crash and lift you up and away from danger.

A supercar that can't crash would be very popular among the ultra rich even at 5 mil a pop.


> Maybe it could be sold as a safety feature.

Yeah, loading high pressure gas into tanks in your vehicle structure is a "safety feature"...


it won't be street legal pretty much anywhere, to quash any further speculation


I would love a non-street legal car ... that didn't need streets.

The car is fun as a concept. Amazing as a demo. And the actual street legal versions will still be fun and amazing to drive relative to "ordinary" hypercar criteria.


"hypercars" should be illegal on streets too


> ”It's being sold in two modes. One with cold gas (no combustion) … and one with real combustion rocket engines”

No, both versions use cold gas thrusters. There are no combustion rocket engines involved here.

The difference between the “thrust” and “rocket” versions is the number of thrusters: “rocket” has additional thrusters that enable it to fly. The “thrust” version just has them at the back for acceleration.


Can't help but recall the JATO Rocket Car

https://en.wikipedia.org/wiki/JATO_Rocket_Car

The famous JATO Rocket Car story was one of the original Darwin Awards winners. I remember reading it out loud to my buddies and us all rolling withlaughter when it was published in News of the Weird. pre-Internet.


One of the best episodes of Mythbusters when they recreated this.


The first or second time?


I think this was the FIRST episode.


Rocket version also has an additional 400 liter COPV which takes up the passenger seat. Thrust version has a 200 liter COPV behind the seats.


Interesting. Air is approx 1 kg/m^3, so that tank is 0.4 kg at 1 bar, and a typical COPV can go to say 300 bar, so we're talking 120 kg.

For a 1000 kg car and with 200 m/s nozzle exit velocity, to hover the car you need (with m_0 g = m_a v/t) about 50 kg of air per second, so we're talking about roughly 2.5 seconds of flight (from those 400 litres).


I believe the COPV was capable of 10k psi [1] or ~690 bar. The 400L is in addition to the 200L tank giving 600L total, which means roughly 300 kg of nitrogen. At that pressure the Z factor is around 1.5, so it’s closer to 500 kg/m³ than the 690 the 1 kg/m³ approximation gives. With the car at just under 1700 kg [2] you need about 83 kg/s to hover at 200 m/s, so you get roughly 3.5 seconds. That’s before tank mass and pressure falloff though.

Damn, maybe it doesn’t matter and a flying car has many other things to worry but I’d be shitless scared to sit next to anything that has 690bar of hydrogen (or even air).


You need to use 150 bar on average because the pressure will drop while it is being used.


You're right, there's a factor 1/2 missing. Should've studied my integrals.


It look to me you also forgot to account for the weight of the propellant still in the tank.
