It would actually be easy enough for Walmart to switch to paper debit cards that had the amount of the card printed on the front. When you used that card, the cashier simply gave you lower-denomination of cards (say, a $5 debit card when you paid for a 5 dollar item with a $10 debit card).

Once this practice became pervasive enough, unfortunately the government would have to step in to create rules and regulations as to how all the printing would appear, and to prevent fraud. I suggest they mandate the use of engraved printing plates; green magnetic ink; and heavy cotton rag for the card. Oh, and to certain security features like holograms, watermarks, embedded plastic strips, etc.

My god, the level of convenience we'd enjoy would blow away any other form of paying for goods and services literally overnight.

Peasant Han: "Honest officer! Our child was sold into slavery over a year ago!"

Officer Zau kicks over the wood stove, lifts open a patch of the tile floor and shines his light into the darkness below. A dozen eyes shine back.

Officer Zau (screaming): Zui cha. Chaqu. Yongyuan!

Officer Zau unholsters her Type 15 pistol, takes aim at Han and puts her finger on the trigger.

Is there any other kind?</snark>

I recall an old Science Fiction story along the same lines, back in the early 80s.

The protagonist was a young man in a third-world middle-eastern shitehole. He was tired of war, of losing friends and families, when he had a revelation: the "Blue Hats" (UN) were neutral, so if he joined their "army" he'd be relatively safe and wouldn't have to fight any more.

So, he obtains a discarded steel pot and paints it blue. Reveling in his newfound "immunity," he convinces his friends and neighbors to do the same. Even the other side starts doing it until everyone is a Blue Hat -- and peace breaks out for the first time in living memory.

I forget how it ended, but the gist was that the First-World was using the Third-World as a "live culture" of warfare, to keep the former's own troops trained and budgets justified. The old sides were eventually convinced to go back to fighting one another.

google broke into internet search with the page rank algorithm whose essential purpose is to combat "search engine optimization."

Yeah. They destroy legitimate businesses with their wonderful algorithms...

SEO isn't a legitimate business. If your website is getting pushed into the search-result basement, odds are you're doing it wrong.

I think most doctors believe its beneficial but I also think they somehow see acetaminophen opiate formulations as some kind of bulwark against abuse. Either because they believe it is so much more effective paired with acetaminophen and you'll be inclined to take less overall or that people "know" acetaminophen is bad in quantity and it will serve as a deterrent to excessive dosage, especially people with a history of drug abuse.

Also, the DEA watches doctors who prescribe opiates very carefully. If some government goon believes a doctor's handing them out like candy, the doctor's most likely going to be called in for some very uncomfortable questions. See chapter two of Three Felonies a Day for some examples.

The way scripts for opiates are handled is also quite different. My wife's oncologist was able to submit the vast majority of prescriptions to her preferred pharmacy electronically; they would be ready for pick-up a short time after. The one time she was prescribed straight oxycodone (or whatever opiate), it was printed on security paper to thwart attempts at altering or copying. It was signed, and some sort of DEA ID number issued to the doc was printed in the header. I had to deliver the prescription to a pharmacy. Her usual pharmacy didn't have it in stock, so I had to find another that did. Once it was filled, I had to sign for it in a logbook (similar to when you buy products containing pseudoephedrine).

You went long on Demand Media stock, didn't you?

That butthurt's gotta burn!

As intrusive as the Google Glass has proven to be, it will only be worse when observation recording tech is more difficult to detect.

I disagree. The exact opposite: when people stop noticing, they will stop caring. It won't be perceived as intrusive anymore, and people will be less annoyed by it.

It's the conspicuousness of the camera in Google Glass, the constant reminder that you might be recorded, that makes most people feel creeped out. For the previous decade leading up to that product, nobody cared about small+cheap camera tech itself. And people walk/drive by fixed-position cameras all the time, and don't give a fuck there either. Peoples's behavior shows that "intrusiveness" happens when a cameras looks like a camera, and I suspect it also has something to do with being face-level, literally "in your face" and you're making eye contact with it, unlike the case with less conspicuous cameras. It was never about privacy; it's some aspect of self-consciousness kind of related to privacy, but a different thing.

You might say "maybe you, but I sure care. Hell yes it's about privacy." Of course you say that. I'm talking about how people behave and the emotions they display. Not their innermost secret thoughts that they are always terrified to express in voting booths or policy decisions, yet are happy to speak of on the Internet.

You know, the Internet, where they don't have a camera in their face making them all self-conscious! The Internet, where instead of a terrifying 1x1 pixel image that makes you think "WTF is that? That's weird! Are you watching me?" you now instead see a bunch of "like buttons" which are obviously for liking things, not getting your browser to send a request to an unrelated tracking server.

In addition, there's a certain inevitability about it all. The cameras have been there a long time, there are more today, and there will be even more tomorrow. You can't do anything about it, except stay at home. So you'll either accept or you'll go insane and get selected out. You'll handle it. (Contrast that to Google Glass, the one small camera out of the hundreds out there, that you actually recognize and is also rare enough that there's little social cost to shunning. With GG you can refuse to accept and also stay within social norms, so GG is different.)

Bitcoin's primary purpose is to traffic/launder money and goods.

Objection. Will stipulate that its primary purpose is to traffic. But I call mega-bullshit on its primary or even secondary purpose being to launder, though there might be a way one could use Bitcoin for that.

How does the Tor Project get safe harbor? They're not an ISP.

In that case, it gets thrown out one step sooner, since they're even less involved than an ISP would be.

Android 4.x devices like the Nexus 7 don't have a dedicated menu button. And in this copy of Google Maps, there's no "tricolon" button where the overflow menu is supposed to be.

https://support.google.com/gmm/answer/6054498?p=maps_android_tips_tricks&hl=en&rd=2

The first thing that came up on my phone for this? "Popular tip: View maps offline." I got to it from within Maps by opening the menu off to the left side and hitting "Tips and Tricks" down at the bottom.

(This was on a Moto X running Android 4.4. YMMV.)

IMHO all this tech is basically good, but I should point out that I also consider a large wooden horses to be basically good things, too. (They can be neat works of art, or convenient sources of fire wood.) That doesn't mean I'm saying you should wheel all the ones you find, through your city gates! There are other issues besides the utility value of wooden horses. It's the tech that should be celebrated, not necessarily all the products that use it. Tech and products are two very different things, even if related.

There's a pretty easy way to judge the ads for this stuff: what protocols does the product speak? Do you already have software in your repo that speaks that protocol?

And of course, you don't necessarily have to use someone else's service to get the device to work, right? (I'm not even saying you necessarily shouldn't use their service, but if you have to then the product is almost certainly garbage.)

Nice. "Darn it, this amusingly tiny-capacity obsolete tape drive isn't powering up. I must have forgotten to bring its .. uh .. [glance around suspiciously] battery. But I paid $800 for it in 1996! *sigh* Ok, TSA agent, you can have my tape drive.. and .. oh no! My ink jet printer isn't working either! You mean I forgot both batteries!? Dammit! So much for printing those colored pie charts on the plane for my .. uh .. presentation. Boy are your kids going to be happy Xmas morning. [glare slightly unconvincingly at TSA agent]"

[Later, on Xmas morning] "Here you go, Billy. You were a bad boy. I never loved you."

[But Billy turns out to be cool] "Whoa! I can salvage the head servo and reel motor from this tape drive, and build something nifty with my Arduino! OMG, does this printer have a stepper motor?"

I think this idea is getting up into the "three birds, one stone" territory.

Tried to read the first book. Barely literate drivel.

Sometimes people need a little help. Often (but not always!) they'll half-suspect the problem, and will prefix their remark with "is it just me, or..."

You didn't do that, but I'm going to be a pal and pretend you did, and then answer the question for you:

Yes, it's just you.

I say try because in a battle between a jet engine with the power to push 400 tons of steel into the sky VS a drone I'm going to put my money on the jet engine lasting long enough for them to turn around and land again.

You might want to rethink that after being reminded of jet airliners being brought down by birds - not an ounce of metallic content, just a few pounds of meat and soft lightweight bones - or the 747 which almost crashed after all four engines failed from ingesting some ash. (Fortunately, they happened to be relatively near an airport and were high enough to glide for over a hundred miles, which bought them just enough time to restart an engine while they had been preparing to ditch in the ocean, buying them enough time to limp to the nearest runway - although all four engines were damaged beyond repair.)

For that matter, the French Concorde which crashed in 2000 was destroyed by a single thin strip of metal, 17 inches long and just over an inch wide, less than four ounces: essentially, a slightly larger than average metal ruler. It didn't even go into an engine, it just burst a tire - violently enough that the ten pound lump of rubber ruptured the wing and number 5 fuel tank, causing the crash which killed everyone on board.

That was a single 4 oz strip of metal hitting a tire. A pound of bolts or nails will destroy the engine - or a metal drone engine that size.
