That 15% loss reduces your range from 1000km to 850km? That hardly affects how useful the vehicle is. For EV that’s different story.

How many vehicles have a 650 mile range? Almost none. Plus you can't fill up at home with gasoline, like you can with an EV.

'22 Ford Escape hybrid

The remaining miles thing shows less than that on a full tank, but I've been pretty consistently getting upper-600s between fill-ups.

I suppose it would probably be less if I went on the interstate more.


There's one. Go to a Car and Driver article about cars with extreme ranges, namely those over 650 miles, and they will start listing out particular years' models over a 10 year period in order to get to even ~10 models, and most of them are EcoBoost or variants or poor selling hybrid versions of other cars.

Assuming a 1000km range is a very strange thing to do, as it's a fringe feature that almost no one needs or wants! Recall that "almost no one" means that there's still some, an existence of a handful of people on HN is quite consistent with "almost none."


Of course I didn't pick it for range, I looked at price and miles of what the local carmax had and then separately looked up how tall the top of the windshield was.

Which I would expect to typically find something that's, um, fairly typical on characteristics I wasn't selecting on.


my 2010 F-150 with the notoriously terrible 5.4L gas engine seems to manage 1000km range. there's absolutely nothing efficient about it, it's just got a big gas tank.

Yep, Ford had to put really big tanks on even the F150 to make up for the horrid mileage. Even with a 36 gallon tank, when towing with an F150 you might only get 300 miles. It's one reason the Lightning had problems selling as many as they wanted (aside from the ridiculous pricing the first year or so). Most people who are serious about towing don't use an F150 anyway, but that doesn't mean that F150 buyers don't fantasize about their potential towing needs in the future.

Comparing range of gasoline cars is idiotic. There are plenty of cars with long range (1000km), and they all have 60L+ fuel tanks and most run on diesel (which gives you ~15% more range per liter). It'd even argue the same for BEVs. More battery is more range.

you can have drum of fuel enough for entire winter in your garage, the fuck you mean by "can't fill up at home"?

They mean that rounded to the nearest percent, 0% of people will be filling up their car at home from a drum.

rounded to nearest percentage zero people have winter-related car issues in the first place...

The point you are DESPERATELY trying to miss is you can easily "recharge", a "dead" ICE at home too


Every modern passenger car will show you 650 miles when driving at ~60mph. In the EU, anyway, and with a diesel engine.

90% of passenger cars in north america are gas powered

Not so in EU

You mean EVs? Yeah, none that I'm aware of. But petrol/diesel cars? Loads of them. Even my 400bhp Volvo XC60 will easily do 650 miles on one tank of fuel. A diesel one will do 700-800. And a diesel Passat will go over 1000 miles on a tank without trying. Hell, even my basic 1.6dCI Qashqai could do 700 miles on its 55 litre tank

Volvo xc60 has an estimated 25 mpg overall (https://www.volvocarsrichmond.com/volvo-xc60-mpg.htm)

It has an 18.8 gallon fuel capacity (https://www.volvocars.com/lb/support/car/xc60/article/dfc6f0...)

That’s a max range of 470 miles. You would need much greater fuel efficiency above 34 mpg to get to 650 miles on an 18.8 gallon tank.


Cool, I guess when I did 700 miles on a single tank of fuel driving Switzerland to Italy and then again driving Italy to Austria and then again Austria to Netherlands this summer I just imagined it. My total for the 3000 miles was 38mpg(imperial).

Also you are quoting a value for the B5, which is not what I have, mine is a T8(and before you ask - no, I didn't have any opportunity to charge it anywhere on the way).


Well the 1.44 MB, was called that because it was 1440 KB, twice the capacity of the 720k floppy, and 4x the 360k floppy. It made perfect sense to me at that time.

It may "make sense" but that's actually a false equivalence. The raw disk space for a 3.5" high-density floppy disk for IBM PCs is 512 bytes per sector * 18 sectors per track * 80 tracks per side * 2 sides = 1,474,560 bytes. It is 1.47 MB or 1.40 MiB neither of which is 1440 KB or KiB. The 1440 number comes from Microsoft's FAT12 filesystem. That was the space that's left for files outside the allocation table.

Sectors per track or tracks per side is subject to change. Moreover a different filesystem may have non-linear growth of the MFT/superblock that'll have a different overhead.

Not my downvote, good chart actually.

It is worse of a downer when there is a complete failure to make further sense like that, but I'll try to do something.

Of course one chart does not an expert make, I don't understand half of it but at least I worked with 3.5 floppies since they first came out.

3.5 floppies are "soft sectored" media and usually the drives were capable of handling non-standard arrangements too. What made non-standard numbers of sectors uncommon was it would require software most people were not using. DOS and Windows simply prepared virgin magnetic media with 2880 sectors, or reformatted them that way and that was about it.

PC's were already popular when 3.5 size came out, and most of the time they were not virgin magnetic media, they were purchased pre-formatted with 2880 sectors (of 512 bytes per sector) already on the entire floppy, of which fewer sectors were available for user data because a number of sectors are used up by the FAT filesystem overhead.

On the chart you see the 1440kb designation since each sector is considered 1/2 "kilobyte".

512 bytes is pretty close to half a kilobyte ain't it?

(The oddball 1680kb and 1720kb were slightly higher-density sectors, with more of them squeezed into the same size media, most people couldn't easily copy them without using an alternative to DOS or Windows. Sometimes used for games or installation media.)

With Windows when partitioning your drive if you want a 64 GB volume you would likely choose 64000 MB in either the GUI or Diskpart. Each of these GB is exactly 2880000 sectors for some reason ;)

But that's the size of the whole physical partition whether it contains only zeros or a file system. Then when you format it the NTFS filesystem has its own overhead.



Maybe more like a fatbike for the mind: pretending to cycle with zero effort and exercise.


Do you mean the column artifacts in the 3d rendering? It is rendering incorrect on my aging iPad.


Watch the video to the very end: the final splat is not a gaussian one.


The article didn’t go into this, but I suspect that a large part of the dark mode trend is due to evening/night computer use. If you don’t light your room, the screen is the only light source which is unpleasant.


I would argue that you don’t need to learn string theory as it currently does not predict anything we can realistically observe (as you need energies that occurred only at the big bang). If string theory is correct we could observe a “supersymmetric” twin of all known particles, however we haven’t seen these, and they could exist even if string theory is false.

String theory aims to explain all physics as manifestations of a mathematical concept best understood as a vibrating string.

Initially, the hope was that string theory could predict the particle masses we observe, but that hasn’t worked as it turns out there were many different predictions possible. String theory has also struggled to develop a version of the theory that does not contradict known properties of our actual universe.

Loop quantum gravity is not equivalent to string theory, except that it also tries to unify gravity and quantum physics.

As things stand, string theory is not falsifiable, while that is the case, you could argue it does not count as physics.

But, by multiple accounts, it is interesting math, which can be worth doing for its own sake, and it’s happened often enough that interesting math turned out to be useful somewhere. Just not for explaining physics.


Maybe the following helps: if you have a an analog signal where there are no frequencies above 22.05 khz, it is in principle possible to sample it at 44.1 khz and then perfectly reconstruct the original signal from those samples. You could also represent the same analog signal using 48 khz samples. The key to resampling is not finding a nice looking interpolation, but rather one that corresponds to the original analog signal.


This is a story about a unique 1947 Chinese typewriter prototype that never got built. It could type thousands of characters by combining keystrokes. The prototype was presumed lost, found this year and it is now at Stanford.

This is not news, but I read about it here today in a Dutch newspaper article (paywalled, untranslated): https://www.nrc.nl/nieuws/2025/12/27/lang-verloren-gewaande-...
