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.

  • Apparently Valve experimented with melee weapons early in development, but intentionally decided to cut them because of the perceived lack of impact and weightlessness of held items, but the main thing was that playtesters kept getting their long melee weapons snagged on stuff. Alyx notably does not allow your hands or held items to intersect with other objects, nor does it let your hands get too far away from your body’s position to prevent shenanigans. If you unexpectedly hook your crowbar on a door frame or a table or something you’ll find yourself inexplicably leashed to it after walking a couple of feet and then not be able to find your hands.

    This article goes into some detail. Apparently the crowbar specifically was removed to prevent players from assuming they were Gordon Freeman, despite the constant stream of evidence to the contrary. But it doesn’t seem like too much of a leap to replace that with Alyx grabbing a random length of pipe or chunk of rebar or something from the multitudes of trashed urban environments she traverses throughout the game.

    Anyway, as soon as modding support was opened up for HL:A the first things that inevitably appeared were about 4,987 mods that added the crowbar back in. So it’s an easy enough wish to fulfill, if that’s what you want.



















  • The TLC NAND chips used in most commodity memory cards these days are only good for something like 1500 write cycles per cell before they are prone to wearing out and coming back with errors. The difference between a dedicated SSD and a dinky memory card is partially the amount of extra space reserved for relocating data as the memory cells wear out, of which a consumer MicroSD card typically has little (on expensive ones) or none (on cheap ones).

    I’ve heard it said, or rather seen it written, that some TLC NAND can endure “up to” as many as 3000 write cycles, but everyone is cagey about the true number and most consumer grade card vendors are tight-lipped about what kind of chips are actually in their products. So in other words, if you’re just scarfing a cheap card off of Amazon or from Microcenter or whatever, don’t expect ironclad longevity.

    The one thing with flash storage writes that’ll bite you and it’ll bite you fast is logging. Unix-like systems love to incessantly write little one line additions to oodles and oodles of log files all the time, and if you want to extend your poor overworked little SD card’s lifespan you can dabble in turning some of that stuff off, once you’re positive you don’t need it for troubleshooting.

    There also exist high reliability cards sold for industrial embedded applications, which will use lower capacity SLC but be able to endure upwards of 100,000 write cycles (per the marketing literature, at least). Expect capacities to realistically top out at about 64 gigs and for a single unit at that capacity expect to pay north of $100 for the privilege. It may be more appealing to use an NVME SSD at that rate and connect it with USB adapter or a hat.


  • Interesting to see where this leads, but I’m not terribly excited about this yet. The article mentions, but doesn’t necessarily explain, how these are supposed to work with pancake lens assemblies — only that they propose that they are. One of the major problems with those is light loss, which is the stated reason Valve went with LCD rather than OLED for the Steam Frame. LCD brightness can be fairly trivially increased simply by… well, making the backlight brighter. LEDs, on the other hand, largely provide their luminance as a function of the surface area of the die. If you make them smaller it also makes 'em dimmer, and there isn’t any mention of whether or not TCL has somehow managed to overcome this. That may explain the rather underwhelming bump in panel resolution.

    Option B is just to drive them harder, which is probably not a great plan for an OLED panel’s already finite lifetime. The blue subpixels die first, then the greens, then the reds…
