Off-and-on trying out an account over at @tal@oleo.cafe due to scraping bots bogging down lemmy.today to the point of near-unusability.

  • I use “mono-9” in all my terminals, including for emacs. On my Debian trixie system, that maps to DejaVu Sans Mono in the fonts-dejavu-mono package.

    $ cat ~/.config/foot/foot.ini
    [main]
    font=mono-9
    $ fc-match mono-9
    DejaVuSansMono.ttf: "DejaVu Sans Mono" "Book"
    $ fc-list|grep DejaVuSansMono.ttf
    /usr/share/fonts/truetype/dejavu/DejaVuSansMono.ttf: DejaVu Sans Mono:style=Book
    $ dpkg -S /usr/share/fonts/truetype/dejavu/DejaVuSansMono.ttf
    fonts-dejavu-mono: /usr/share/fonts/truetype/dejavu/DejaVuSansMono.ttf
    $
    

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

    The DejaVu fonts are a superfamily of fonts designed for broad coverage of the Unicode Universal Character Set. The fonts are derived from Bitstream Vera (sans-serif) and Bitstream Charter (serif), two fonts released by Bitstream under a free license that allowed derivative works based upon them; the Vera and Charter families were limited mainly to the characters in the Basic Latin and Latin-1 Supplement portions of Unicode, roughly equivalent to ISO/IEC 8859-15, and Bitstream’s licensing terms allowed the fonts to be expanded upon without explicit authorization.

    The full project incorporates the Bitstream Vera license, an extended MIT License, which restricts naming of modified distributions and prohibits individual sale of the typefaces, although they may be embedded within a larger commercial software package (terms also found in the later Open Font License); to the extent that the DejaVu fonts’ changes can be separated from the original Bitstream Vera and Charter fonts, these changes have been deeded to the public domain.[1]



  • There are some memory latency benefits to putting memory on a single chip, but to date, that’s largely been handled by adding cache memory to the CPU, and later adding multiple tiers of it, rather than eliminating discrete memory.

    The first personal computer I used had 4kB of main memory.

    My current desktop has a CPU with 1MB of L1 cache, 16MB of L2 cache, 128MB of L3 cache, and then the system as a whole has 128GB of discrete main memory.

    Most of the time, the cache just does the right thing, and for software that is highly performance-sensitive, one might go use something like Valgrind’s cachegrind or something like that to profile and optimize the critical bits of software to minimize cache misses.

    I could believe that maybe, say, one could provide on-core memory that the OS could be more-aware of, say, let it have more control over the tiered storage. Maybe restructure the present system. But I’m more dubious that we’ll say “there’s no reason to have a tier of expandable, volatile storage off-CPU at all on desktops”.

    EDIT: That argument is mostly a technical one, but another, this one from a business standpoint. I expect PC builders have a pretty substantial business reason to not want to move to SoCs. Right now, PC builders can, to some degree, use price discrimination to convert consumer surplus to producer surplus. A consumer will typically pay disproportionately more for a computer with more memory, for example, when they purchase from a given vendor. If the system is instead sized at the CPU vendor, then the CPU vendor is going to do the same thing, probably more effectively, as there’s less competition in the CPU market, and it’ll be the PC builder seeing money head over to the CPU vendor — they’ll pay a premium for high-end SoCs.

    In Apple’s case, that’s not a factor, because Apple has vertically-integrated production. They make their own CPUs. Apple’s PC builder guys aren’t concerned about Apple’s CPU guys extracting money from them. But Dell or HP or suchlike don’t manufacture their own CPUs, and thus have a business incentive to maintain a modular system. Unless one thinks that the PC market as a whole is going to transition to a small number of vertically-integrated businesses that look like Apple, I guess, where you have one or two giant PC makers who basically own their supply chain, but I haven’t heard about anything like that happening.



  • Aside from them, discrete graphics cards are history, just as disk controllers were a few decades earlier. DIMM slots are going too. The primary storage will be built in. (The industry missed a great deal there.)

    Discrete disk controllers are still around.

    My last desktop had a PCI SATA card that I added after I exhausted all of the on-motherboard SATA slots.

    My current one has a JBOD SATA USB Mass Storage enclosure.






  • Ehhh.

    When I saw the title, I thought that someone was trying to use LLM-backed bots to drive some sort of marketing campaign or something.

    But this sounds like it’s just someone plugging in something into an LLM and it returning the same kind of stuff that a Web search engine would.

    Reporters fed national-language versions a range of prompts, including requests for online casinos with the biggest bonuses and websites that don’t ask for proof of age to register.

    In three quarters of replies, chatbots recommended gambling sites not licensed in Europe, describing them variously as “secure and fast”, “perfect for competitive players”, or “great for novice gamblers”.

    Casinos that lack national licenses for countries where they operate do not offer the same consumer protections as legal operators, and may expose players to the risk of scams or fraud.

    When prompted, the chatbots explained how software could be used to access unclicensed platforms and promoted sites registered in offshore territories. One Meta AI chatbot wrote that online casinos with no identification checks were the “Holy Grail!”. Google’s Gemini said crypto sites offered players “anonymity” and a “lack of rigid limits”.

    I have a hard time calling that “luring”.


  • cheaters

    If I were set on that, I’d probably play on a console. I prefer keyboard+mouse for shooters, but…

    The PC’s strength is that it’s open. You can do whatever you want. Want to mod a game to have more features or make it look prettier? Go for it. Tweak it? Sure. Get more-powerful or newer hardware to get a more-attractive appearance in a lot of games? Sure. Cheat to skip that annoying grindy bit in game X? Sure thing. Use whatever new and interesting input devices you want to add quality-of-life features with an extra button or macros? Sure.

    Works beautifully for single-player games.

    But by the same token, attempts to resist cheating in multiplayer competitive games are ill-suited to the platform and rely on developers trying to hack together attempts that tend to have performance and compatibility implications and work imperfectly. It’s hard to try to lock down an open platform.

    Whereas the strength of the console is that it’s closed. You can’t do whatever you want. You don’t get to mod or tweak games much, which eliminates routes to get an edge via exploiting that. Everyone has (more-or-less) the same hardware, so nobody can “pay-to-win” in the sense of getting a performance edge in multiplayer competitive games — there’s a level playing field. A lot of PC gaming hardware is ultimately driven by trying to sell some way to basically let players pay-to-win, to get some edge in competitive multiplayer, which isn’t something that most players much like having around — and consoles don’t have that problem. Cheating is a pain. I understand that these days, console vendors blacklist and authenticate alternative input devices, so that players can’t use alternative controllers and the like, which prevents them from getting an edge.

    Works beautifully for competitive multiplayer games.




  • Kinda shooting for the feel of like an old school Lenovo laptop keyboard

    If you’re specifically set on that, there used to be a USB-attached version of those. Dunno if they still make them. Wasn’t really interested myself, since I don’t like low-key-travel keyboards if I can avoid them, but I distinctly remember seeing them.

    searches

    Apparently it was called the “Ultranav”. I don’t see new ones on Amazon (other than someone trying to sell one at an exorbitant $400), but there are used ones:

    EDIT: Well, some of those say that they’re new. shrugs
