arh68··on Tell HN: I think I found Toyota's battery
Your numbers seem off...

Base models: 3,370 vs 3,968. Flagship models: 3,800 vs 4,663.

So 600-850 lbs differential. Not 1,000, but not just an extra person.

To be fair, the Hyundai does seem larger (12" longer wheelbase).

arh68··on First new US nuclear reactor in decades enters commercial operation in Georgia
2 units, both 1,100 MW each. So 2 cents / kWh.
arh68··on Lazydocker: a lazier way to manage everything Docker
Like Quick Find? The apostrophe? '

I agree this style of navigation is great. I don't know if it's in Chrome, though.

arh68··on LCD TVs won’t see any further development
Panasonic ended their Viera line about 10 years ago, unfortunately. AFAIK they were the last &/ the best.

Mine still works great, although it still draws ~200 watts of energy.

arh68··on The myth of the $600 hammer (1998)
The "myth" is quite real, e.g. the $1,000+ coffee cup

arh68··on Ask HN: A good IDE/environment for programming beginners?
> Java ... are easy enough to setup (thanks to JetBrains) but ... there are no good books teaching novices the CS foundations using these languages

Really? Is there no good Java book?

I can't actually name one off-hand, but surely... even if it covers only Java 8

arh68··on Gas-powered leaf blowers: The end is nigh (2021)
> But these machines persist in American landscaping because they are cheap.

I rarely see pros use cheap stuff. They're paying for Stihl eq and mowers I can't even afford.

2-stroke gas eq is incredibly powerful for the weight. More power, more done, more money.

Battery is catching up quick, and honestly will soon deliver even more power, and that's when I think most will switch. I bet many will pay more for a (more-powerful) battery trimmer. But it's not about "cheap" (imo).

arh68··on Chess, unlike war, is a game of perfect information
There is some truth to this.

In theory, chess is a game of perfect information.

But in practice, this is only true for ~6-piece endgames: every outcome has been / can be computed. But for any middle- or early-game position, the amount of finite information greatly exceeds any person's or computer's capacity, practically speaking.

In concrete terms, the tablebase for 6-piece endgames is ~150 GiB. For 7-piece, it's 16 TiB.

arh68··on Bookshop.org survives and thrives in Amazon’s world
I just bought some books from Powell's. It's kind of a landmark in Portland.

arh68··on All the Buns Are Blank
They hardly had any sesame seeds to begin with.

Big Marty's still have a ludicrous amount. I guess it's all or nothing.

arh68··on How to design a sailing ship for the 21st century? (2021)
> Two rowing machines could provide roughly 400 watts of power. If they are operated around the clock in shifts, they could supply the ship with an extra 9.6 kWh of energy per day

Rowing 200 watts is not exactly easy. That's like 2:00/- splits, "ramming speed" type power. Half that seems more reasonable.

I do like the idea, though, of a sailing ship with ad hoc erg/rowing power.

arh68··on Modern Mono
The tournament thing is kinda fun, but deep down I think we know which we like best.

For me, it's serif fonts

1. Triplicate A Code

2. NSimSun

3. Courier Prime

Sans serif fonts certainly have their own appeal

1. The Sans Mono (the O'Reilly book font) / Fira

2. APL385 Unicode (this font's got maybe the best numbers)

3. Mononoki

Pixel fonts, classics (but maybe best on low DPI)

1. Fixedsys Excelsior 3.01

2. 6x13

arh68··on ChatGPT: The Slickest Con Artist of All Time
I think "con artist" isn't too far off, but "dream simulator" also applies.

I think it's kind of an open question: can we learn anything from dreams? It's likely a yes, though I doubt we'll prove the Riemann hypothesis with it or anything like that.

arh68··on Cistercian Numerals
Reminds me a lot of the D'ni numbers from Riven.

D'ni numerals overlay two base-5 values in the same space, one horizontal & the other vertical, to represent 0–24. There's even a one-character numeral for 25, though it rarely comes up in-game. Different, of course, but I wouldn't be surprised if Cistercian was the inspiration.

arh68··on Moving the Ctrl Key
Or you're hunt-and-pecking at 30wpm on your coworker's QWERTY keys, and they start to look at you funny as you stammer something about "I'm not used to ..." and "... Dvorak"? Yeah.
arh68··on Fast midpoint between two integers without overflow
Erlang's got them, I'm pretty sure.
arh68··on Why do new cars look like wet putty?
2 things

1. it's not that the colors are themselves bad, but that the author feels the trend is being forced upon their whole generation

2. there are a number of not-very-grey pastels that I've seen on the road: Subaru's Hyper blue WRX STI, Toyota's Voodoo blue 4Runners, Dodge's orange Challengers, soon Nissan's new yellow Z, ... so maybe the author is too focused on what they dislike

Re: 1, it's funny because I always felt metallic colors were thrust upon us all for 20 years, a trend with its own missteps. Remember the green metallic early-00s Altimas? Worse than any grey pastel I've seen. But it doesn't indict the whole metallic category.

Personally, one of our first family cars was a pastel close to butter. (nowadays, my car is silver metallic)

arh68··on The factory that only builds white Toyota Land Cruisers
Tacomas switched to the 3.5L 2GR-FKS with port + direct injection (& Atkinson cycle), years ago.

4Runners still have the old 4.0L 1GR-FE, port-injected. (and a 5-speed automatic! you're right about low-change mentality)

Fuel economy is roughly similar (>= 11.0 L / 100 Km), as far as I know, as is power.

arh68··on DVD sales surpass Blu-ray in 2021: Physical format market
I used to buy more Blu-Rays but some TV series have stopped disc releases, presumably to drive streaming, or just aren't worth buying.

Expanse: Season Five, specifically: why must I get Prime when I've got Seasons 1 - 4 on disc? And who's gonna buy GoT S5-8? Westworld S4?

I've got no comment on any increase in DVD sales, though. That's not my market. I only rip CDs (which skip like crazy, while I've literally never had a disc issue with DVD/Blu).

arh68··on Software Mimicry
So are the birds mimicking the bees, or is it the other way around? Maybe I'm just missing the point.

I mean, is int[] a mimic of ArrayList<Integer>, or vice versa? Of course they're similar, of course they're different. Is "mimicry" just a pejorative thing?

arh68··on Copilot under fire as dev claims it emits 'large chunks of my copyrighted code'
Right. It just seems like a matter of time before MS strikes / takes down someone's original code for "infringing" upon Copilot output.

Seems like above a certain size, stealing becomes a great business strategy.

arh68··on Ask HN: Why don't I see gold at the end of the remote working rainbow?
> others that just abhor having to talk to real-life people

No, buddy, just people like you.

If you really feel your job is slaving at a digital conveyor belt if you can't socialize with coworkers/friends, I just don't know what to say.

No offense, but you kinda sound like an asshole.

arh68··on Lost something? Search through 91.7M files from the 80s, 90s, and 2000s
Your description reminds me of Crystal Quest / Crystal Raider.
arh68··on Go: Redefining For Loop Variable Semantics
This seems reasonable. As others state, this is hardly an issue specific to Go.

In CoffeeScript (which I think solves this nicely), it looks something like

  for i in [0...3] # 3 3 3
    setTimeout (() -> console.log "#{i}"), 100

  for i in [0...3] # 0 1 2
    setTimeout (do (i) -> () -> console.log "#{i}"), 100

  for i in [0...3] # 0 1 2
    do (i) ->
      setTimeout (() -> console.log "#{i}"), 100
arh68··on Why do all these 20-somethings have closed captions turned on?
FWIW, adding a Center channel to my former 2.0 seems to have really helped me hear dialogue.
arh68··on Dark Sky iOS app will no longer work from Dec 31
Along these lines, I also really like the Aviation Radar maps

(feel free to change, in the top left, Type = Comp Ref, and to Loop)

arh68··on Ask HN: Which password is more secure?
In theory, they could be seen as equivalent. In practice, they're not. Your "2,154" speaks to that.
arh68··on Ask HN: Why are chess problems attack oriented?
I'm not really sure what the difference is. The best defense is a good offense, no? I'm only about 600 puzzles in, on lichess. Sometimes you must out-attack (race to checkmate), other times you just want to get ahead before you disable their attack.

Maybe you like the Quiet Move type puzzles? Those are a weak spot for me.

arh68··on A pipe operator for JavaScript: introduction and use cases
The lodash equivalent, which I missed, is something like this:

  _.chain(inputSet)
      .filter((x) => x >= 0)
      .map((x) => x * 2)
      .thru((e) => new Set(e))
      .value()
I think it looks fine, works fine.
