    You know, not really a problem that I’ve thought about, but outerwear is gonna limit what people can show from a fashion standpoint.

    I’m not aware of any effort by clothing designers to really work on the problem, but I wonder if it’s possible to make outerwear that thermally-insulates, but is transparent.

    I don’t know if it would run into problems like fogging up on the inner surface and that messing with transparency. If so, it might be possible to mitigate that via use of forced ventilation coupled with an inverse-flow heat exchanger, or maybe using some kind of hydrophilic insert to absorb moisture.

    goes searching

    What I get for “transparent jackets” is mostly raincoat-type things, thin sheet of plastic.

    The problem with those is that those can’t do much to insulate.

    There’s also this:

    Which probably will do something to insulate, since air insulates pretty well, but the bending plastic on the sides of the air pockets are going to do a number on the aesthetic, since one can’t see clearly through it.

    What I guess one would want would be a substance that thermally-insulates, is transparent, and also doesn’t act like a lens to distort what’s on the other side.

    Aerogel is one of the best thermal insulators we have, so you’d need very little thickness to provide a very great amount of thermal insulation.

    It can be at least somewhat-transparent; most shots I’ve seen look kind of like a cloud:

    And it looks like people are looking into using a thin layer on windows, as effectively-transparent insulation:

    It’s also extremely strong.

    However:

    • It’s rigid, which isn’t ideal for clothing; the human body moves, and if you want it to fit to form, it has to be able to contour to it. That being said, we have made human clothing out of rigid substances before, like chain mail — you just need to segment the stuff into small pieces. To some extent, outerwear doesn’t need to contour to form; hoop skirts, for example, didn’t. We have made clothing out of joined, rigid metal plates before; it’s clearly at least possible, though outside of armor and sheer novelty of aesthetic, I don’t think that we’ve ever really had a practical reason to actually do so:

    • I understand that it’s also damaged by contact with water. This can be dealt with by coating it with something that protects against water, but that stuff has to be able to resist being punctured. Need a transparent coating, maybe some kind of plastic, maybe Gorilla Glass or something.

    • It’s presently (relatively) expensive to make. My guess is that that can probably be overcome; industrial diamonds used to once be pretty expensive too.

      searches

      It looks like these people have a flexible, composite blanket partly made out of aerogel and billed for use in apparel, though they’re not trying to make something that’s transparent (and their composite is even more expensive).



  • It’s not, and I think that Excel is often used where other tools would be more-appropriate because of existing expertise with Excel, but you don’t necessarily need to use a database for all tasks where a bunch of data gets stored.

    I have plenty of scripts that deal with large amount of schlorped up data that just leave it in a text file, and Unix has a long and rich tradition and toolset for using text files for data storage and processing data in them in bulk.

    GNU R, a statistics package, has a lot of tools to schlorp up data from many sources, including scraping it from the web, and storing it large data frames to be processed and maybe visualized. It’s probably rather more performant than databases for some kinds of bulk data processing.

    Okay, so…is it appropriate here?

    One thing that spreadsheets can be handy for is for making specialized calculators that plonk some data into some simple model and spit out a result. Having, say, the current temperature in a given city may be a perfectly reasonable input to make available to a spreadsheet, I think.




  • “They’ll find a reason to impeach me,” Mr. Trump said. “I’ll get impeached.”

    Maybe. They almost certainly won’t have enough to convict you, though, can’t remove you. I do expect that you and several of your cabinet are probably going to spend the second half of your term sitting in front of House investigations, though. You’ve done probably enough things that probably warrant investigations for a dozen Presidents.

    I’d also add that in 250 years, we’ve had four impeachments of Presidents:

    • Andrew Johnson

    • Bill Clinton

    • Trump.

    • Trump. Again.

    Somehow, all this time, opposing parties haven’t generally gone out and impeached the President. The X factor here is you.



  • I’m not familiar with FreshRSS, but assuming that there’s something in the protocol that lets a reader push up a “read” bit on an per article basis — this page references a “GReader” API — I’d assume that that’d depend on the client, not the server.

    If the client attempts an update and fails and that causes it to not retry again later, then I imagine that it wouldn’t work. If it does retry until it sets the bit, I’d imagine that it does work. The FreshRSS server can’t really be a factor, because it won’t know whether the client has tried to talk to it when it’s off.

    EDIT: Some of the clients in the table on the page I linked to say that they “work offline”, so I assume that the developers at least have some level of disconnected operation in mind.

    The RSS readers I’ve always used are strictly pull. They don’t set bits on the server, and any “read” flag lives only on the client.


  • If you mean Battle Angel Alita, wasn’t it based on a manga or something? That should have more story.

    searches

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

    Battle Angel Alita, known in Japan as Gunnm (銃夢, Ganmu; lit. ‘gun dream’),[a] is a Japanese cyberpunk manga series created by Yukito Kishiro and originally published in Shueisha’s Business Jump magazine from 1990 to 1995. The second of the comic’s nine volumes were adapted in 1993 into a two-part anime original video animation titled Battle Angel for North American release by ADV Films and the UK and Australian release by Manga Entertainment.

    looks further

    Oh, you’re probably talking about the 2019 live-action movie. Didn’t even know that they’d done that. Huh. Kinda like Ghost in the Shell, I guess.



  • A second problem is that if a much beloved movie (or video game) comes out, there’s a window of time where you can make a sequel with the same team, actors that are about at the same age, and so forth.

    But if you let 20 years go by, that team is gone. Some may be retired, some are doing other things and won’t come back, actors will have aged, etc. You’re going to have a hard time assembling a group with the same chemistry again.

    I think that in many cases, it’s better to do a similar work. Like, okay, say you like a space opera like Battlestar Galactica or Firefly or something. I liked both. But…trying to do more of same is going to be a tall order. A lot of times a new team tries to get continuity by lots of in-jokes or allusions to the original that the original team probably wouldn’t have, and I think that that can be a negative. If it’s a live movie, it’s probably going to be hard to get ahold of props from the original and such any more. Like, I’d rather just have someone go do a new, good space opera in the same vein that tries to emulate the good bits of what I liked about the original. A spiritual successor rather than an actual one.

    I’m not saying that it has never been the case that there have been good sequels done by other people. I like the Fallout video game series, and it’s had a variety of teams and companies that have done entries. But I think that there have been a large proportion of attempts to build on past IP using a new team that just don’t work out.



  • Minutes after that exchange, the libertarian pundit took to X/Twitter and ripped Trump supporters who were attacking her over a long-held position

    Yeah, I suspect that Trump’s going to make a bunch of right-libertarians pretty unhappy, many of whom want less US foreign involvement. He basically spent a long time appealing to people who wanted less US foreign involvement (e.g. with Ukraine) and then turned around and jumped right into foreign involvement in South America, which probably isn’t going to sell well with them.

    I saw several articles over the past couple days where Rand Paul and Thomas Massie, who are pretty visible Congressional voices along right-libertarian lines, were complaining about Trump intervening in Venezuela.

    Probably fewer of those than there are, say, social conservatives, but I expect that for a lot of them, Venezuela is gonna be a sticking point.

    Secondly, is there a benefit to creating an LVM volume with a btrfs filesystem vs just letting btrfs handle it?

    Like, btrfs on top of LVM versus btrfs? Well, the latter gives you access to LVM features. If you want to use lvmcache or something, you’d want it on LVM.
