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.

  • The enzyme products are generally meant to be a maintenance thing, i.e. if you use them regularly they remove light buildups of crud stuck to the inner walls of your pipes before they build up into being thicker layers of crud, which become blockages (or just reduce the effective inner diameter of your pipes).

    This stuff might theoretically clear the right kind of total clog, but it’s likely to take a long time.

    My advice is to get yourself a drain snake. Chemical clog clearing products “may” work, with various pros and cons depending on the type of clog. But physical removal of the clog with a snake always works, you will never run out of your bottle of snake, and provided you manage not to fuck it up so badly that you break it the snake is also infinitely reusable.

    Just get one of those 50’ long jobbies you can put on the end of a drill. That’s just fine for most residential work and should only run you $20 or $30 at the hardware store.










  • This is the correct answer.

    For anyone who wants an acceptably flat surface on a shoestring budget — or free — any piece of modern glass will do it. Even that out of a cheap picture frame. Modern float glass is extremely flat. Maybe not to optical lab grade standards, but certainly enough to render the gap between any two given objects small enough to fit on any piece of glass you’re likely to be able to lay your hands on straight enough that you couldn’t slip a piece of paper in between. Supply your own wet-or-dry sandpaper.

    This is also useful for mirror-finishing the bottoms of heat sinks or the bevels on chisels.



  • I don’t think anyone has much issue with our current write speeds, even at dinky old SATA 6/GB levels. At least for bulk media storage. Your OS boot or game loading, whatever, maybe not. I’d be just fine with exactly what we have now, but just pack more chips in there.

    Even if you take apart one of the biggest, meanest, most expensive 8TB 2.5" SSD’s the casing is mostly empty inside. There’s no reason they couldn’t just add more chips even at the current density levels other than artificial market segmentation, planned obsolescence, and pigheadedness. It seems the major consumer manufacturers refuse to allow their 2.5" SSD’s to get out of parity with the capacities on offer in the M.2 form factor drives that everyone is hyperfixated on for some reason, and the pricing structure between 8TB and what few greater than 8 models actually are on offer is nowhere near linear even though the manufacturing cost roughly should be.

    If people are still willing to use a “full size” 3.5" form factor with ordinary hard drives for bulk storage, can you imagine how much solid state storage you could cram into a casing that size, even with current low-cost commodity chips? It’d be tons. But the only options available are “enterprise solutions” which are apparently priced with the expectation you’ll have a Fortune 500 or government expense account.

    It’s bullshit all the way down; there’s nothing new under the sun in that regard.
