The fake PIN would work against trojan ATMs. I've seen more than one story on the news where fraudsters install a fake, free-standing ATM in a public shopping area (mall). It reads the cards and PINs, and maybe dispenses cash (or some sort of error message). The "service technicians" later remove the machine with all the recorded info. for cloning the cards.
People love the heydays, though. Ah, for the days when you could teach yourself to fly in an Army-surplus Jenny! Now you need a license to be a passenger.;) My most recent hero-god engineers died (in happy retirement) a decade ago. Possible sign of a muturing market: art majors started finding that they needed specific graphic arts degrees in order to make it to the end of job interviews. "Nice portfolio, but your degree is in the wrong field."
In short, your industry is "mature" when you need standardized govt-/industry-approved training and licensing to practice your craft. "May I see your Z-Java license sir? Your C++ license is worthless here."
The upside is that you don't have amateurs building public bridges or skyscrapers, or screwing up expensive print jobs. What about the software?
It's not "on fire", it's 17 billion Joules worth of electrons screaming "wheee!" as they jump back down through their energy levels (I love Forrest Mims' smiley electrons). There's no air in an incandescent lightbulb, either.
One thing I miss about the old This Old House is the DIY aspect. The homeowners were expected to do some of the work, and most of the clean-up. So, what used to be Bob saying "Now Norm will show us how to raise this wall and put in new blocks" is now Steve saying "Now Tommy's crew will show us how they use several rams to lift this wing while injecting new poly-cement to level the structure."
At the risk of wandering into OfftopicTrollsville, it's the advertizers that are buying a product from the broadcasters. The product? US. The viewers. Eyeballs, hearts and minds.
At that point, why not just use a barcode or magnetic strip, like current documents? It ends up the same as a shielded RFID tag: official/clerk must open document and pass over scanner. Sure, that may require connection to a central database, but the main drawback is that there are no high-tech taggy thingies!
This drilling, as well as trepanning and some forms of massage, could also be explained as a method of releasing or removing the "evil wind" from the body part. Your tooth feels like it's about to explode with pain? Let's drill a hole in it to release that pesky demon!
My 10-yr-old bought three UMD movies after he first got his PSP. He watched them on road trips and sleep-overs with his friends. Now I find the movies in a drawer in the kitchen, with the scissors and tape! This boy obsesses easily, but lately the handheld/console market has him yawning. Now he's got to have a pair of (expensive) Heely wheely shoes.
I went through an "All Ellison, All the Time" phase. The stories are fantastic, and generally warped my outlook. As a side affect, I spent some of my time between volumes just thinking "Get it out! Get it out of my brain!" Ah...good times.
I imagine the same research could help develop human prosthetics. Having to grow and feed a sensor might someday apply to artificial skin or retinal tissue. Or maybe just a better connection between the mechanical implant and the cells that control it.
I have an old Kensington Expert Mouse trackball, and I think they're still about the same size. I've switched to the Microsoft Trackball Explorer on my new system, but the Kensington is still on the older "game" machine. And yes, I have to keep my 2-year-old from running off with the ball.
The point is that collisions between the debris already up there are enough to continue to drive up the piece count, even if no one launches any more mass.
Atmospheric drag is like a little retro-thrust at perigee, which will not change the perigee altitude, but will lower the apogee alt until the orbit is roughly circular. After that it tends to decay "circularly". Highly eccentric orbits (geo transfer) have other non-intuitive effects.
But Kessler's "cascade theory" allows for stable populations. Once a certain critical density is reached, collisions will quickly drive up the debris population; but the increase may reach a new (higher) stable density of debris objects (objects per cubic km). The overall risk of collision is then higher, and a new critical density can be defined which would lead to the next run-away cascade.

Reaction probably varies from person to person, since some people in this study of poison ivy became more sensitive with repeated exposure.
Personally, I'd squish the buggers anyway, rather than let them reproduce.

A quick check shows they'll all reenter within (at most) 5 to 15 years, which is within the usual safety standards. See some related NASA materials.

Maybe they could modify the process to drool out biodiesel.

I'm turning Japanese I think I'm turning Japanese I really think so.
Hmm... Maybe I can go down to the siezed-property auction to bid on some MP3s? They'd sound really great in a siezed drug-boat.

It's no joke, it's The Voluntary Human Extinction Movement!
It will also drink all your beer and give you Dutch Elm disease. Over here is more, equally vital information.
There are a lot of interesting tips for up-and-comers. The site could be anywhere from a missile silo to a private island.
Also check out the K-12 Linux project. They have lots of info on installing and running Linux classroom workstations.

I saw this referred to in the Encyclopedia Astronautica (no images). There's also a section that lists the "leading" proposed manned Mars missions.
