    Or just fix the original machine? Older micros were quite simple, often using widely available microprocessors, memory, and glue logic. There's not much prior to 1983 that can't be fixed with new parts from Mouser/Digikey/whoever, a soldering iron, some time, and possibly a low-end oscilloscope.

    We have precise head aligning technology that can hover easily just nm above the platters, we have printer heads capable of printing nm-scale.

    Zips wouldn't be able to come close to the areal density or speeds of today's hard disks. They're still floppies, just with better media and a better enclosure. Plastic film that thin isn't dimensionally stable enough to work under the conditions required even if you could get the oxide coating fine enough.

    And I'll bet my Disk IIs are older than your 1541s, and will read/write a hell of a lot faster. Having said that, I have quite a few Amiga 3.5" disks from 1986 or so that still read just fine. I've since transferred them to ADF files, and almost all my Amiga stuff gets done in an emulator now.

    And rest secure in the knowledge that in many cases, they're made up of entirely off-the-shelf parts and are easy to fix if something breaks. Part of the reason I prefer the Apple II+ over the IIe.

    I remember having to cram some sparse information into the tiniest amount of memory I could devise because more memory wasn't an option.

    It's often still like that in the embedded world. Hand these folks one of the original TI Launchpad experimenter boards and see what they think of a 256 byte memory limit.

    In a normal person there is a known relationship between breath alcohol level and blood alcohol level.

    It's a *presumed* relationship, not a known one, and can be skewed by any number of variables. Plenty of cases based on Intoxylizer results in particular have been thrown out because CMI refuses to allow courts to know exactly what the assumptions made by the device are.

    This shows you why America's liberal weapon laws are advantageous . . . if your kid runs up high costs on games . . . you can take him or her out in the backyard and blast their brains out with your Heckler & Koch MP7!

    Funny that you mention "liberal weapon laws" and "MP7" in the same sentence. Full-auto MP7s aren't legal for any regular citizen to own in the U.S. *at all*. If you can manage to find someone that can actually import an SF model, good luck finding ammo for it.

    Many ISPs do have the flexibility for alternate handling of DDoS, up to a certain point, they can avoid Null-routing an IP, or avoid the Null-routing of one IP from making your service unavailable.... generally, the cost will be much higher --- E.g. $10,000 per month instead of $100 per month.

    This is what it comes down to. If you want real DDoS protection, it's going to cost real money. If you can't/don't want to pay that, then you'll just have to deal with the nullroute. Cheap prices mean cheap service.

    I hope so, but I don't think there's going to be a quantum leap in performance with the laser machines until you can get a decent beam-steered galvo head + flat field lens for under a few thousand bucks.

  13. What didn't exist - I don't think - was decent, affordable, small mills.

    That, and the widespread knowledge of how to run the axes safely (accel/decel curves and whatnot) without tearing things up. I was in a similar situation as you, but with laser marking/engraving machines. The desktop laser machines of today, while useful and wonderful to be able to have on your desktop, still don't really compare even to the industrial machines of 20 years ago. Moving the beam with a cheap pair of steppers is quite different than running it with high-end servos and having to deal with accel/decel periods and delays that have to be accurate to the microsecond.

    Milling metal, even something soft like aluminum, will still result in razor-sharp chips getting everywhere. Cleaning the machine and your work area is something that will require some care, and heavy gloves because those chips can cut your hands to ribbons if you're not careful.

  21. Re:Good for them on Dutch City To Experiment With Paying Citizens a "Basic Income" (theguardian.com) · · Score: 1

    Just using quick back of napkin calculations, if you enacted a $10k / year basic income for all adults you could get rid of almost all welfare programs.

    I'm not sure how that works. $10K/year is about 2/3 of minimum wage, and plenty of people making more than that are still on some kind of assistance. Even in a two-parent home with both parents getting $10K each, it's going to be very tight.

    This would probably greatly decrease the costs of low-skill labor intensive expenses I have like the $3200 per month I spend on daycare

    Now that's just silly. $100/day for daycare? That's more than twice the U.S. national average and closer to about 5 times what most people actually pay. That kind of money would pay for a full-time nanny to watch the kids the entire day. If you do have a nanny, be advised that there are already plenty of ways to bring your costs down.

    But.. it does at least feel right for the first half.

    For the most part. It still bugged me to no end that Rey was familiar with the Falcon's legendary feats, and familiar enough with it to fly it, but didn't recognize it during all the years it sat there in town, or even when they were looking for a ship for their escape from Jakku - the moment it touched down at the lot for storage, I'd have thought it would have become an instant celebrity. It also bugged me that Finn went to the lower gun seat and somehow still managed to pick off the TIEs even though Rey was hugging the ground for a good part of the chase - the upper gun would have made a lot more sense. And snap zooms had no business being in there *at all*. This is Star Wars, not Firefly or BSG.

    I need to stop now, or else I'm going to come up with more.

    Really? From your link:

    USB Type-C devices also support power currents of 1.5 A and 3.0 A over the 5 V power bus in addition to baseline 900 mA

    3 amps x 5VDC x 4 power conductors is roughly 60 watts. With a 5V supply, 150 watts would require 7.5 amps per conductor, which is just barely accommodated by four 13 gauge conductors. Of course, the four ground conductors are going to need to be just as big as well, so you're looking at a damned big cable unless you've got some DC/DC converters in the cable ends to step the voltage up.
