  • I would be opposed to requiring it. I think that even an example from another state or country might have useful bearing on how things work elsewhere.

    I mean, end of the day, if you’re going to go out and ask anonymous people on a forum legal questions, I think that it’s safe to say that it might be a useful starting point for further investigation, possibly involving talking to a lawyer. But I wouldn’t go do something with major risk based just on what they say. I don’t think that it’s going to be really practical to change that.

    Some people can taste certain chemicals in some vegetables much more strongly than other people and really don’t like them.

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

    Supertasters are individuals whose sense of taste for certain flavors and foods is far more sensitive than the average person.[1] The term originated with experimental psychologist Linda Bartoshuk and is not the result of response bias or a scaling artifact but appears to have an anatomical or biological basis.

    Reports of variations in human taste perception date back to 1888.[5] The major advance in understanding human taste variation came in 1931 with the discovery of “taste-blindness” specifically for thiourea compounds, when Arthur L. Fox, a chemist at DuPont, discovered that some people found phenylthiocarbamide (PTC) bitter, while others found it tasteless.[6][7]

    Fox describes the event:

    Some time ago the author [Arthur L. Fox] had occasion to prepare a quantity of phenyl-thio-carbamide, and while placing it in a bottle the dust flew around in the air. Another occupant of the laboratory, Dr. C. R. Noller, complained of the bitter taste of the dust, but the author, who was much closer, observed no taste and so stated. He even tasted some of the crystals and assured Dr. Noller they were tasteless but Dr. Noller was equally certain it was the dust he tasted. He tried some of the crystals and found them extremely bitter.[8]

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

    Phenylthiocarbamide (PTC), also known as phenylthiourea (PTU), is an organosulfur thiourea containing a phenyl ring.

    It has the unusual property that it either tastes very bitter or is virtually tasteless, depending on the genetic makeup of the taster. The ability to taste PTC is often treated as a dominant genetic trait, although inheritance and expression of this trait are somewhat more complex.[2][3]

    https://www.compoundchem.com/2014/12/04/brusselssprouts/

    At this point, you’re probably wondering what this has to do with brussels sprouts. Whilst the compounds PTC and PROP aren’t found in the vegetables, they both contain within their molecular structure a thiocyanate group (nitrogen, carbon and sulfur bonded in series) which is thought to be related to their bitter taste. This same group is also present in compounds called glucosinolates, which occur naturally in brussels sprouts, as well as broccoli, cabbage and kale (collectively known as cruciferous vegetables). The glucosinolates are thought to form part of the plant’s defence systems , for example against diseases and creatures that feed on the plant. Additionally, the breakdown products of glucosinolates, the isothiocyanates, also contain the thiocyanate group within their molecules.

    So why is this structural similarity significant? Well, there seems to be a strong association between the ability to detect the bitter taste of PTC and PROP and a sensitivity to the bitterness of these vegetables. Of course, it’s not the case that sensitivity to PTC and PROP automatically implies a dislike of cruciferous vegetables; other factors may also have an effect, such as a person’s particular flavour preferences. However, if you’re a brussels sprout hater, you can now suggest a potential chemical reason for your dislike if you’re ever berated for your perceived vegetable prejudice.




  • I think that the mathematical concepts that I learned were mostly generally useful.

    But what was useless was the emphasis on doing work by hand. My particular pet peeve is all the time I spent in calculus classes being taught techniques to do symbolic integration by hand.

    I was doing a math project once, working with the husband of one of my calculus professors. He himself was a mathematics professor. I dropped by his office. He had to work something out that involved a symbolic integration and fired up Mathematica. I said “You can probably do all this by hand”. He laughed and said something like, “Nobody who has to do actual work with this is going to waste time doing this by hand”. He was right.

    Today, I use maxima to do symbolic integration. It’s in my Linux distro and on my Android phone.



  • Well, I’m here rather than on Usenet. Overall, I think that the Threadiverse is preferable — Usenet had real spam problems for a long time.

    But if you want some benefits:

    • Wide range of powerful, mature clients with extensive filtering functionality, offline reading support.

    • Better client-side accessibility. I mean, you can be blind and use a screenreader or something on Usenet. Going to be a lot less ideal on the Threadiverse.

    • Comment editors are probably better than the in-browser textarea editors or clients with limited text-editors that I’ve seen (though the Threadiverse has Markdown as a standard, which I think is generally preferable). Though I haven’t been browsing Usenet in some time, and maybe they have MIME-encoded Markdown or HTML or something as a common thing now.

    • More-standardized support for posting embedded binaries.

    • Commercial service is available. It’s great that people donate their time and funds to make Threadiverse servers run, but there’s something to be said for the resources available from commercial service. There’s nothing stopping someone from running a commercial Threadiverse instance, but AFAIK, nobody presently is doing so.

    • Newsgroups are more discoverable than are communities on the Threadiverse — you really need to use the https://lemmyverse.net/ index to find any communities out there, as otherwise you’ll only see it once the exact name “!community@instancename” has been searched for on your local instance. Usenet (mostly) propagated newsgroups everywhere.

    • Probably a larger userbase, though I haven’t dug up current numbers. Certainly a different group and set of interests.

    • Some PGP use and client support.

    • I would bet that Usenet servers can scale up to more load than can Threadiverse servers.


  • I’ve used a Kobo that has a limited browser, but if she wants to browse the Web, I’d just get an Android tablet rather than a dedicated hardware e-reader. She can run the Kobo or Amazon or whatever apps on an Android device, as well as run reader apps for PDF or whatever.

    IMHO, the major reason to get a hardware e-reader is to have an eInk screen. If she’s going to be doing anything other than the most minimal of web browsing, she’s most likely not going to want an eInk screen.


  • I just overheard a coworker saying “Oh, I would never try that in my life!”, in a discussion of food. (This was about consuming a steak cooked less than medium well). It made me wonder what life is like for those who refuse to try new food, especially those who refuse to try mundane things like fried shrimp.

    I mean, they might be concerned about health risks. Cooking is part of our process for making a lot of food safe to eat.

    I mean, I wouldn’t worry about a medium steak, but I wouldn’t eat steak tartare. It isn’t because I’m worried about the taste or texture, but because I don’t want to pick up parasites or similar.








  • The keyboard interface sucks

    I’m not sure if you’re going to see this if you’re avoiding social media for two months, but…while I don’t personally see much gain from using a phone rather than a PC for Internet access for two months, if it’s enough of a pain and it doesn’t violate whatever rules you’re setting for yourself, you can connect a keyboard. There are a bunch of Bluetooth keyboards aimed at Android devices, some of which fold and are themselves phone-sized for portability.

    https://www.amazon.com/s?k=folding+keyboard

    You can also get USB-C hubs with pass-through charging, stuff like this that will give you some USB-A ports to plug wired keyboards into, if you’re using the phone at a desk.

    Android won’t show the on-screen keyboard if you have a connected physical keyboard, so you also get a lot more screen space while doing text entry.

    Most if not all UIs for websites are shit in mobile.

    Firefox (and probably other browsers, but I use Firefox) can request the desktop version of websites. Tap the menu button in the lower-right, and then choose “Desktop site”.

    Now, the desktop site may not work well on a small screen either, but you will have access to it.


  • I think that it’s fine technically — the ML family of languages have extensive static typing functionality that I like — but Rust has enough overlap in functionality and has greater uptake. (I say this not having spent enough time to really come up to speed on Rust myself.) A quarter century back, ocaml was the language that I was most impressed with for strong static typing functionality. In 2026, I think I’d probably look at Rust and only go to ocaml if Rust doesn’t suit your needs.

    As to whether it can be a “daily driver”…I mean, you can use any language daily. I do think that it’s hard to appreciate how helpful it is to have all the examples and library support and tools until you move from a popular language to a less-used one and suddenly discover that you want something that isn’t there.

    So can you use it? Sure. Is it the first option I’d recommend to someone who — and I assume that this is why you’re looking at it, if your alternative is Python — wants to move to a statically-typed language? No. Is it a terrible choice? No, it’d also be a long way from the bottom of the list that I’d recommend.
