  1. Re:Hard to believe on The Last of the Punch Card Programmers · · Score: 1

    A screw machine is a super-specialized brother of a turret lathe but a CNC mill can machine pretty much anything. So its a "specialized task" vs "general purpose" battle.

    The article seems to focus on how the old machine uses punch cards to actuate instead of a PLC and some solenoids or servos, which seems irrelevant to making better lace. So its a binary data format battle.

    The best machinist analogy I can come up with is claiming an old bridgeport with a PDP-8 CNC controller reading gcode off papertape somehow magically produces higher quality parts than my current Linux/EMC2 controller system, which I find unlikely.

  2. Re:The Clorox solution on Researchers Develop "Tea Bag" Water Filter · · Score: 1

    One cap full for a bucket of water. It tasted terrible,

    The water treatment guys screwed up. Chlorinated water shouldn't taste awful after purification, certainly not even as bad as swimming pool water. The "art" of chlorination is to use just enough hypochlorite to oxidize all the microbial life, anything over and above that is wasting supplies, aim for the "faintest taste of chlorine". Also you can aerate the water, just pouring it from cup to cup for a few minutes will help noticeably. Storing treated water after Cl dissipates will allow whatever was growing in there to start growing again, so theres little point in stockpiling treated water. The point I'm making is, assuming the water treatment dudes were not totally incompetent (which is possible despite 3rd world conditions), a canteen full of dog pee would be perfectly safe to drink after treatment, but won't taste good. So there's some reason other than Cl2 content that the water tastes horrible, and frankly you probably don't want to know why. Dead animal carcass upstream, manure runoff/sewage leakage upstream, dead fish suction-stuck to intake grates, etc. The foulest "treated" water seems to come from swamps full of decaying everything.

    Now you want foul tasting treated water, try iodine purified water. That stuff is foul, but iodine stores better than chlorine compounds, more stable. Great for 3rd world. All halogens taste / smell pretty much the same and your Dr buddy might not have known better.

  3. Activated Charcoal on Researchers Develop "Tea Bag" Water Filter · · Score: 0

    Its just a bag of activated charcoal. Great at filtering out larger organics, not so good with microbial life forms and minerals.

    I bought "cassette tape" sized bags of activated charcoal for my tropical fish tanks in the 80s. Glad to see the technology reinvented.

    I'm not sure any amount of AC can protect fish from nearby rotenone spraying, then again its very hard to prove that without the AC bags my fish would not have died, its not like I was about to tempt fate. Thus plenty of opportunity for psuedo-science. Which MIGHT be where this product is headed, maybe.

    This could be due to many other factors than just alcohol. What about the food?

    The same people that don't want to live near a prison won't want to live next to a current prisoner.

    So, if the law is an offender can't live within 1000 feet, simply build a school or playground every 900 feet and its all good. This strategy is actively being done in my area. Admittedly, why you'd want to raise kids more than 1000 feet from a playground or school is a mystery to me, but it has the side effect of forcing the offenders into rooming houses literally built inside industrial parks... Which is not all that bad of an idea, unless your dream was always to live next door to a tannery or a chicken processing plant.

    Why lifetime punishment is considered acceptable for a crime generally considered less severe than murder is a whole nother topic.

    A bigger problem is ankle bracelets having iffy rx coverage inside a car/van.

    Also, understanding the system doesn't work too well, the punishment wasn't all that severe for screwing up. The idea being that this would be used as an "in-between" not as a replacement. Most people completely misinterpret it as being a replacement for prison, when its 50/50 that its actually a replacement for outright complete freedom. The original article is pretty misguided.

    You set a curfew. Either they are at work (at the times they are supposed to be working) or they are at home (at the other times). If they are not at home, the GPS system will detect that and alert the cops that they have broken the curfew (and may be committing a crime).

    Too simplistic, doesn't work. People also need to eat, go to the dentist, go to the emergency room, go to the doctor, apply for work at a better job, go to the pharmacy, get their interview suit from the drycleaners, work unanticipated mandatory overtime, AA meetings "often" intentionally scheduled during prime drinking time, etc. And if the criminal either has kids living in their house or even just has kids at all, its pretty much free range as long as there is a tenuous connection to "its for the children".

    I speak from experience given my neighbor has nearly double digit drunk driving convictions, and on his latest work-release / probation / house arrest / whatever the heck its called, he pretty much got around MORE than I did.

    From discussion, since its virtually impossible to live outside prison under house arrest, no one does, and it simply means the parole officer bullies folks she/he doesn't like as an individual or as a (protected minority) group. Being a married with children white semi-educated good ole boy sorta-middle class sportsfan, coincidentally pretty much identical to his parole officer with the exception of adding a serious drinking problem, he had few hassles, but I'm told minorities tend to have a very rough time of it.
