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.

  • America.

    Retailers are allowed to disclaim the merchantability and fitness for any particular purpose of the items they sell and most do. The customer is free to refuse, of course, via the simple expedient of going away and buying it somewhere else.

    This is partially a blame-shifting exercise to reduce costs, yes, but it’s also a shield against the ceaseless horde of dipshits we have in this country who will willfully misuse a product and then immediately try to sue the retailer they bought it from when it doesn’t work or they hurt themselves with it via their own stupidity. It is much easier from a legal perspective to make a blanket “we don’t imply this product is applicable for any purpose” statement vs. having to explicitly predict whatever cockamamie thing someone might try it on and have to say “no, moron, that chainsaw is not suitable for cutting bricks,” etc.

    Read all that fine print on the back of your receipt some day. You will be enlightened and, most likely, also infuriated.







  • Was it actually him? I was under the impression that history did not relate what happened to him afterwards, nor who he was. That’s not to say the CCP did not murder a couple of thousand people during the crackdown regardless, because they did, but I have never seen a verifiable claim that a picture of any particular corpse actually was the Tank Man. There are numerous theories I’ve seen floated over the years alleging what may have happened to him afterwards ranging from him being caught and imprisoned, executed, living anonymously in China, or fleeing to Taiwan. All of them are unverified and, of course, mutually exclusive.

    The tank operators absolutely did attempt to (and succeeded at) avoid running him over. That much is plainly visible in the video. Whatever happened after the video ended is undocumented and pure conjecture. Plenty of well documented atrocities actually were committed that day, before and after that moment, so there’s not much sense in inventing new ones and bickering over details we haven’t actually got.



  • That’s probably because the current Abrahamic incarnation of god and his attributes are carefully designed to be a non-falsifiable claim.

    So the point is actually rendered moot. God is according to the True Believer invisible, intangible, only works in “mysterious ways,” and cannot be observed to have any influence on the universe, nor leaves any evidence of his existence except “faith.” By those metrics, it’s irrelevant whether he exists or not. A hypothetical force that exists but doesn’t affect anything is interchangeable from a functional standpoint from something that doesn’t exist.

  • For anyone wondering, belay carbiners typically lock in some manner but those used on quickdraws for anchors and removable protection (nuts, cams, etc.) typically don’t.

    A carbiner is strongest when its gate is closed, which is why load rated ones will have not only a gate closed rating (the highest, usually 20-22 kN or even more for steelies), a gate open, and also a lateral load rating. Your belay carbiner, that is the one clipped to your harness and is keeping you affixed to the rope so you don’t hit the deck, is typically not redundant. It absolutely, positively, cannot fail. This is typically the biggest, meanest, strongest 'biner you own and will also be a locking one. You do not want brushing up against things, knocking against it, etc. to cause it to come open. You don’t want it to be open if it suddenly experiences a shock load, i.e. you fall off the wall, or conversely on your belayer’s end if it needs to bear the load of you falling off the wall. And you don’t want it coming unclipped and lost when you’re halfway up, because that’s how you die.

    Meanwhile, the 'biners on your anchors and protection theoretically have some redundancy, i.e. you should be clipped to more than one point along your route with more than one anchor and carbiner. But you need to be able to clip and unclip these readily, because you may well be doing so with one hand while you’re dangling from your fingernails with the other. Thus they do not lock, and you can clip them to something by just slapping the gate against it.

    Your keychain says “not for climbing use” on it. My keychain says Desert Eagle .50 Petzl Angie S, 20 kN gate closed, 9 kN gate open, and 7 kN laterally.
