Progenitor of the Weird Knife Wednesday feature column. Is “column” the right word? Anyway, apparently I also coined the Very Specific Object nomenclature now sporadically used in the 3D printing community. Yeah, that was me. This must be how Cory Doctorow feels all the time these days.

  • I’ve never seen naptha (i.e. Zippo lighter fluid) do anything to any painted or finished surface, nor any of the plastics I’ve ever tired it on. I’ve been using the stuff in that context for decades, to the extent that I literally purchase it by the gallon. (I also use it in my lighters, because painter’s naptha is like 2% of the cost per volume of brand name Zippo fluid despite being the same stuff.)

    WD-40 contains nonvolatile oils that will leave a difficult to clean off residue behind and if you use it on anything porous it will soak in and possibly stain the surface while being functionally impossible to remove without using yet more solvents. For that reason it’s not really a great way to get stickers off of things, especially things that you’d like to remain non-greasy or may need to stick something to again at some point in the future (paint, tape, etc.).

    Naptha will evaporate entirely on its own given enough time, and you can even use it on paper and printed surfaces (excluding inkjet printed things, in my experience, which it will smear) with no harm done after it fully dries.






  • I personally do not trust ISP provided routers to be secure and up to date, nor free of purposefully built in back doors for either tech support or surveillance purposes (or both). You can expect patches and updates on those somewhere on the timescale between late and never.

    Therefore I always put those straight into bridge mode and serve my network with my own router, which I can trust and control. Bad actors (or David from the ISP help desk) may be able to have their way with my ISP router, but all that will let them do is talk to my own router, which will then summarily invite them to fuck off.

    Likewise, I would not be keen on using an ISP provided router’s inbuilt VPN capability, which is probably limited to plain old PTPP – it has been on all of the examples I’ve touched so far – and thus should not be treated as secure.

    You can configure an OpenWRT based router to act as an L2TP/IPSec gateway to provide VPN access on your network without the need for any additional hardware. It’s kind of a faff at the moment and requires manually installing packages and editing config files, but it can be done.



  • You would be amazed in the industrial world. There are tons of large and incredibly expensive special purpose machines that are operated by super antiquated PC architecture computers running geriatric operating systems, sometimes still even DOS or Windows 3.x.

    Think industrial CNC mills and lathes, presses, pick-and-place machines, specialty lab testing equipment, electron microscopes, etc.

    Process control, i.e. production line automation, is usually driven by dedicated PLCs. But the user interfaces connected to them are almost invariantly some old ruggedized panel mounted PC running Windows. An absurd number of them in my experience are still on 2000 or XP. NT4 is pretty easy to find, too.

    Granted often these are not networked, and in cases where they are they’re not connected to the internet, or may even talk to other workstations via RS-485 serial (!) or some other gimcrack method that is unlikely to be a vector for modern malware.


  • What Microsoft probably expects you to do is get your management to buy new computers that support Windows 11 and/or whatever the hell their current server OS is, and in the process give them and their hardware vendor partners a lot of money.

    What you can do instead is switch to Windows 10 IoT Enterprise LTSC which is what I did at my workplace recently. It’s supported until 2032 with security updates. Not feature updates, but I suspect that business users probably don’t care about those much. In fact, most people would probably treat that as a benefit. It also comes with basically no bloatware (except goddamned Edge), which is surprising. No Copilot, no Cortana, no Recall. None of that shit.

    We have a fleet of machines that “can’t” be upgraded to Win11 because of hardware shortcomings, at least without overriding the requirements with Rufus or similar. Unfortunately we also rely on a small but important spread of proprietary Windows-only applications which have no open source or Linux replacements, and at least two of them absolutely will not run in Wine. Believe me, I tried.

    The only wrinkle with this is that you cannot upgrade or license swap in place. You have to do a full reinstall, which for us is not a problem because we have a modest number of computers and I have physical access to all of them. None are bricked up behind a wall or anything.


  • PC operating systems are, at least to a broad degree, generic. That’s because a huge amount of backwards compatibility is built right into the PC architecture, much to the delight or chagrin of everybody depending on who you ask. There’s silicon on your processor’s die right now that’s doing fuck-all except ensuring that if you were struck by the perverse urge, you could boot MS-DOS 1.0 onto it even though it’s virtually guaranteed that you never will.

    Phone operating systems absolutely are not generic, because each phone model is basically unique unto itself in terms of what hardware is in it, and backwards compatibility is not in any way a design goal. Furthermore, the entire package has to be rolled into a single unified ROM image.

    There are proprietary core components in phones, notably their SoCs (systems-on-a-chip) and modems (which are often built into the SoC) which their designers jealously guard and are loaded down with patents and other IP restrictions. This hardware requires closed source drivers which must be updated or at the very least recompiled for new kernel versions if the OS is to be updated. That’s for Android, anyhow. It’s even worse for Apple devices, because they’re entirely closed and Apple is in total control of both the hardware and the software. At least they bother to support their own devices with updates for quite some time, but even they’re not absolved of fuckery – see, for instance, the deliberate slowing-down-with-updates scandal from a few years ago.

    If nobody is providing source code or compatible binaries for the core hardware your phone needs in order to work, at minimum it’s going to be impossible to update your device beyond the kernel version that was last supported on it, even with a custom ROM. And all of this is before getting into locked bootloaders and other chicanery that prevents you from running your own code outside of user space on the hardware even if you had the code to run.

    At the end of the day: The hardware vendors are absolutely not interested in providing driver support to end users or source code to anyone, and the handset makers and most especially the cell service carriers, at least in the US where the majority of people buy or lease their phones from said carriers, literally have a vested interest in dropping support as soon as they can get away with it. That’s because rolling out updates to oodles of individual phone models costs money to do, but they only make more money off of you by selling you a new phone.


  • Just yesterday I created [email protected] for this very purpose, so I’ll plug it again. Well, not miniatures specifically, but rather a place for people who haven’t got printers to ask for help from people who do.

    I’m not in Oz so I figure shipping to you would be quite prohibitive. But you might be able to connect with someone in your country, who can ship printed stuff to you more cheaply and – importantly – without having to fuck around with customs.

    The go-to wisdom is that detailed miniatures are best printed with a resin printer. You can do it with a traditional FDM (filament) printer but it’s harder to get the small details reproduced, and FDM printers can’t print in midair so you either have to be very careful to take that into account with your design or do a lot of work with removing and doing the finish work around printed supports. So you probably want to find somebody with a resin machine.





  • There are oodles of commercial 3D printing services that will run off whatever you send them for a price. Craftcloud, Shapeways, Xometry, etc.

    Or printathing.com, if you’d like to get hooked up with a private(ish) person to do it for you.

    Or just ask at any of the innumerable online spaces where people talk about 3D printing (like right here) and someone can probably do it for you, too.

    My exception is not to people printing things for others for a specific purpose if asked to. It’s against stealing other people’s work and cynically trying to turn it around for a profit, without putting any effort into it and probably implicitly passing it off as if it were your own work in the process. Likewise, I don’t object to someone designing their own thing and selling their own thing on Etsy. But just to put it into perspective I imagine most people would also rank it as Not Cool to go on Etsy and start trying to sell, say, just printouts random stuff you downloaded from DeviantArt.



  • Pretty much all of those are characters from franchises that quickly jumped to consoles, or had the intention of multiplatform releases from the very start. I’m not sure any of them are very fitting.

    So on that note, the least nonsensical mascot for PC gaming in particular I can think of is that dwarf, whoever he is, from the box art of World of Warcraft. Or possibly the orc from the alternate version. WoW is earth-shatteringly popular and has basically defined the entire private lives of a depressing number of people, not to mention it’s the sole and singular thing even non-gamers think of when you mention MMORPGs. And it has only appeared on home computers. Never consoles. Other Warcraft properties have, but not WoW.


  • Define “long.” I disagree with the Doomguy proposal explicitly, because Doom appeared on the Sega 32x in November of 1994 which was barely a year after the initial PC release. One of the defining aspects of gaming in the mid '90s was the monumentally cynical gold rush of trying to cram Doom onto any damn fool console as fast as possible, in a vain attempt to capture part of the lightning and make those sales. And until the Playstation and arguably the N64, every attempt failed spectacularly in various ways.

    The definitive Doom experience remaining locked to the PC for those few years was absolutely not for a lack of trying. Every greedy video game exec on the planet wanted Doom on their system. id themselves assisted with several of these ports in various ways and they had absolutely no intention of leaving Doom only on PC, either, if they could help it.
