re··on Continuous Pitch Wind Instruments
I was curious about the name "glissotar" (less self-explanatory than the in-development glissoflute and glissoboe) but it appears to refer to the Hungarian Tárogató https://en.wikipedia.org/wiki/T%C3%A1rogat%C3%B3

Here's a playlist of songs composed for glissotar: https://www.youtube.com/playlist?list=PLHQMlBq9OKeXINkPCOrLy... (found at https://sonus.foundation/en/page/show/call-for-scores-new-pi...)

re··on Singapore doubles down on lab-grown meat as Silicon Valley backs off
No, the rest is plant-based (wheat- and soy-based protein), like traditional vegan meat alternatives. https://www.goodmeat.co/butchery
re··on “Attention assault” on Fandom
> what license is fandom content under?

Generally, CC BY-SA https://www.fandom.com/licensing

> can an independent entity scrape it and start over?

Sure. The difficult part is migrating the community and competing in search results. Fandom can and does fight efforts to direct people from fandom-hosted wikis to elsewhere. See this other sub-thread: https://news.ycombinator.com/item?id=40711726

re··on Bouba/kiki effect
I realize that, I more meant that I was wondering if the earlier post about the game reminded anyone else about this effect (hence its Wikipedia page being posted here one day later).
re··on Bouba/kiki effect
Not sure if this is a reference to the game "Baba Is You", recently discussed here: https://news.ycombinator.com/item?id=40689759

But that post did make me think of this effect, especially as another character in the game is named "Keke"

re··on Show HN: Shpool, a Lightweight Tmux Alternative
The standard Unix version of nohup does in fact redirect the output/error streams if they would otherwise go to a terminal. https://pubs.opengroup.org/onlinepubs/009695299/utilities/no... / https://en.wikipedia.org/wiki/Nohup
re··on Apple Intelligence for iPhone, iPad, and Mac
Yes. Siri debuted with the iPhone 4s (running iOS 5) in 2011. It wasn't until iOS 15 in 2021 that Siri gained the ability to do some things without an internet connection, on devices with the A12 Bionic chip (the 2018 iPhone XR/XS or later).
re··on Apollo 8 astronaut William Anders ID'd in WA plane crash
I think the parent comment was confusing/misremembering the rotational speed value in miles per hour as miles per second.
re··on How to chop off bytes of an UTF-8 string to fit into a small slot and look nice
Further reading:

* https://hoytech.github.io/truncate-presentation/ / https://metacpan.org/pod/Unicode::Truncate

* https://unicode.org/reports/tr29/#Grapheme_Cluster_Boundarie...

Truncating at codepoint boundaries at least avoids generating invalid (non-UTF-8) strings, but can still result in confusing or incorrect displays for human readers, so for best results the truncation algorithm should take extended grapheme clusters into account, which are probably the closest thing that Unicode has to what most people think of as "characters".

re··on Please support "skip to main content" on your docs site
> Firefox disables tab key navigation on macOS by default

To be more specific, it only navigates between form elements (including <button>) by default. I was curious why Tab was taking me all over a StackOverflow page but not the one linked here.

re··on Go east from Seattle
After this, let's have a calm discussion about whether an airplane can take off from a treadmill that exactly matches the plane's wheel's speed in the reverse direction.
re··on Go east from Seattle
Even if the prompt had been "Imagine a traveling from Seattle along a Great Circle path that initially heads east" to take out the "trick" part of the puzzle, I think I probably would have had a hard time visualizing the path without a physical globe in front of me.
re··on Go east from Seattle
The mental bias towards the Cartesian 2d map projections being what we're so familiar with is strong, and I too instinctively think of "a straight line" as being a straight line on a map. But if you think of the problem at a different scale — say you're standing 50 feet south of the north pole — I feel like you would consider the definition of "face east, then walk forward in a straight line" far less ambiguous.

I'd also point out that it's a puzzle, not a standardized test question. Wordplay, tricks and ambiguities are par for the course.

re··on Show HN: Every mountain, building and tree shadow mapped for any date and time
At zoom levels where buildings aren't loaded, they're treated as casting no shadow, which causes the site to hugely underestimate the amount of shade for dense urban areas. I can see how this would be a hard problem if you're doing the shadow rendering on the client side, but is it something that you have thought about trying to solve?
re··on Instead of “auth”, we should say “permissions” and “login”
They are excellent words but easily confused. See for example HTTP 1.0, which uses "unauthorized"/"authorization" to mean "credentials required"/"credentials", which persists in field names and status codes today.
re··on Show HN: I generated API documentation for all Java packages
1. The text field is actually a filterable "select"-type field, not a raw search. It should show you completions that you should click; if you're not seeing any, you might be encountering some JavaScript error somewhere. It does look like keyboard-only navigation is broken/unsupported, though, which seems important to add -- I'm forced to use my mouse to click the option I want.

2. The homepage requires you to choose an artifact/package first. Click "java.base" and then you can find SimpleDateFormat with the "search" field on the subsequent page.

re··on Show HN: Slice Tap Toy
Nice. Despite the name "tap toy", swiping works well, which is significantly easier with a laptop trackpad than trying to click the pizzas.
re··on How to recover lost Python source code if it's still resident in a running inter (2017)
> If I open a PDF in Preview on my Mac and delete a page from it, it saves the change instantly. If I made a mistake, I can't just close it and re-open the original version.

There's a system setting to (mostly) restore the old behavior: Desktop & Dock > Ask to keep changes when closing documents. Apple applications will still immediately update the file and disk, but it's a lot easier to discard all changes since the last save by closing without saving, and the on-disk file will be rolled back to the previous version. This setting has been around since 2012, I think one OS after they introduced the "auto-save" feature, and I've been using it ever since.

re··on Ilya Sutskever to leave OpenAI
> Alan Turing on why we should never ever perform a Turing test

Can you cite specifically what in the paper you're basing that on? I skimmed it as well as the Wikipedia summary but I didn't see anywhere that Turing said that the imitation game should not be played.

re··on Static Chess
I did something nearly identical to this for the board game Reversi as part of an exercise to teach myself Python, except the opponent was always a simple minimax search-based AI. This was back in 2006, though, so I suppose doing it without JavaScript and putting all of the state into the URL was a lot more obvious of an approach back then compared to today. :)
re··on Show HN: I made an open-source Loom alternative
I'm curious about your plans around open-source, since you're using it as a selling point. There's been a lot of discussion about projects that start as open-source but then go to a more restrictive license once other companies start offering their own hosted versions. Is that a concern for you?

Do you plan to include any/all of the "pro" features on the roadmap in the open-source code?

re··on UTC, Tai, and Unix Time (2001)
Typically operating systems don't maintain a database but instead rely on network time servers to let them know that a leap second is about to occur.
re··on UTC, Tai, and Unix Time (2001)
Note that this page was written in 2001; the leap second situation has gotten a lot more complicated since then, with far more diverging implementations that handle it differently, and no real momentum towards widespread adoption of software that handles them "correctly" (explicitly), like the localtime() "fix" preferred by DJB.

Most people seem to prefer ignoring leap seconds, pretending they don't exist by "smearing" them across the surrounding day, or even getting rid of them entirely. https://news.ycombinator.com/item?id=33658541 https://news.ycombinator.com/item?id=32226414

re··on When do we stop finding new music?
> it’d make business sense to use the equivalent of store brand music

They've been accused of almost exactly this: https://www.musicbusinessworldwide.com/spotify-is-creating-i...

Spotify denies doing this but you can google to find a lot of controversy over fake artists on Spotify.

A more recent variation on the theme: https://www.theguardian.com/uk-news/2024/mar/19/swedish-comp...

re··on American flag sort
Looks like there's a Rust implementation: https://crates.io/crates/afsort

> When sorting English words, this implementation seems to be about 40% faster than sort_unstable from the Rust standard library.

That's better than I would have expected. It would be interesting to see how it does on other types of string sort problems.

re··on Understanding and avoiding visually ambiguous characters in IDs
That uses a different alphabet. https://www.rfc-editor.org/rfc/rfc4648.html#section-6
re··on Understanding and avoiding visually ambiguous characters in IDs
See also Douglas Crockford's Base 32: https://www.crockford.com/base32.html

This takes the approach of allowing ambiguous characters by decoding them to the same value, and also considers the problem of accidental obscenities.

re··on Ruby vs. Python comes down to the for loop (2021)
> his "Stuff" example can be reduced to [...]

The Python example is similarly unidiomatic, reduceable, and flawed for the sake of simplicity (the example doesn't allow multiple independent Stuff iterators), so it's not like Ruby is really at a disadvantage in the article. The point of the example is to illustrate the mechanics of custom iteration (which forwarding to the encapsulated implementation wouldn't accomplish, for either language) while keeping the rest of the Stuff definition as simple as possible. But yes, a brief mention of including Enumerable wouldn't hurt.

re··on My mother declared my bedroom a disaster area (1984)
Also curious that the letter was from May, before the start of the 1984 hurricane season. Per Wikipedia, 1984 did go on to have the highest activity since 1971, while 1983 the lowest since 1930. But 1983 caused more damage with Hurricane Alicia crossing Texas.

The Texas drought reference does appear to be accurate. https://www.nytimes.com/1984/10/16/us/crushing-drought-in-te...
