When I first saw the headline, I assumed somebody had used carbon-fibre paper for the conductive parts, ceramic-fibre paper for the parts exposed to moving hot gas, and some very low-boom combustion mixture - maybe really-lean methane/air, at zero-compression, to make something that could actually turn itself with internal combustion, however inefficiently. It could certainly be done, though that in itself is the only reason to do it. I was disappointed to see the body of the post.
How about a new post, headlined "Functional thermoplastic V8 engine, in production since the 1960s"?
The only BPL tech that will work at all in the rural areas is the Motorola Powerline LV system which uses their "Canopy" wireless links for the long hauls and does short-range local distribution with HomePlug on the mostly-buried LV lines. The HV & MV lines are too lossy to cover significant distance without several repeaters per mile, and those systems will never be deployed anywhere but in areas of high population concentration, where cable & WISPs are already going to be. The companies using the crappy BPL don't intend to, and can't, bring broadband to low-density areas - they just want their piece of the high-yield business already covered by DSL & cable.
The only non-stupid reason this MUST be on the machine is that it is required that these users be permitted to run it, on this machine.
If it is on the machine, root shall be able to read it. If it is possible to execute it, the method of easily decrypting it is present on the machine.
Place it on another machine, executeable only through a network interface, thus making your program itself purely a "black box".
Example 1: Your program is an encryptor, and it takes a key and a data file.
The interface code could be as simple as a shell script that reads the key and filename, and uses a restricted ssh key (on application hosting server, the key is tied to a specific commandline) to transfer the file to a staging location on the application server through scp, run the command, and retrieve the resulting file.
Example 2: Your program passes down a directory tree and creates new files related to existing files.
Simplest solution is like example 1 - script tars up the directory tree and feeds it through ssh to an untar and calls your program on the new remote tree - it could even be a pipe then - you feed your tar directly to a script on the other end that picks a staging location, untars the stream, runs your program on the tree, and sends back the result as a new tar stream. Obviously, it wouldn't be a true stream since the output wouldn't even start until sometime after the completion of input.
If the tree is too big, you put a modified version of your command on the remote that does only the secret part, and a modified version that's publically available to do the obvious part, and outsource the secret work, again through restricted ssh keys.
Example 3: Your program really is a pipe.
You provide a script on your end that just execs an over to that other box with a restricted ssh key limited to running only your command, and runs it.
In my solutions, ssh is a theme - because I don't know the environment, and go with the most secure and flexible solution using service that's likely already approved. For many tasks, you could wrap your stuff up as a cgi script and call it through wget. Maybe write it to listen on a socket and be a plain old service on the box that you control.
If the customer insists that the program itself be present on a box to which he has privileged access and rejects all solutions that don't include that condition, he wants the code. Both of you drop the charade and start negotiating based on that fact.
It's probably not legal,
I don't know about full removal, but I have the fuses for my airbags in the glovebox. I always wheel with everybody belted in, but an airbag detonation would be worse than useless at low speed, and this way, my son gets to sit up front.
It's funny to me to see this idea brought up with a Jeep as the subject vehicle. I've never had anything to do with a Grand, but even though most offroad accessories purchased for them are for purely aesthetic reasons, I have seen some of them, particularly the older ones, which still had live axles, do some competent manoevering. Anyway: The architecture of a traditional body-on-frame engine/transmission/transferase/driveshaft/liveaxl e 4WD vehicle lends itself to just such modifications. If I ever implement the specific thing I have in mind, you'll see it on ROF, and maybe even on/..
The Cherokee is no joke
And neither is the Grand Cherokee(a completely different vehicle, not just a larger version of the Cherokee) - particularly the last generation back - with live axles. The extra width hampers them on narrow spots, but is doubtless a comfort when off-camber.
Everybody who cares, and has a claim, should do it on the phone, even if he has the required combination available, and make a big deal about it as well. Then, they should follow up with a letter to their congressman. Congress won't call hearings on this particular issue, but if there are any intelligent representatives, and they bring it up in the already-inevitable hearings...
Just once, I'd like to see one of these lazy MS-centric idiots in a nationally-televised "What were you thinking?!"
Actually, the morse guys were amateurs as well. Neither of them has ever had a job in which use of morse code was part of the job.
The earlier contest, on which this one was based, was held in Australia, and was much more lopsided. The SMSer was a high school girl who did NOT have the world record, and the morse code guys were 90-year-old retired telegraphers. It's been a very long time since anybody got paid to send morse code.
Chip and Ken are amateur radio operators, K7JA and K6CTW. The tonight show staff just dressed them up like old-time telegraphers. VILLAGER #1: Well, we did do the nose.
BEDEVERE: The nose?
VILLAGER #1: And the hat, but she is a witch!
The big advantage they had is not the quality of their paddles nor the lack of time shifting (the twirp wasn't anywhere near done sending when they finished). They could send every letter with their fingers on the same buttons. Sending text from a cell phone is like hunt-and-peck typing. Sending morse code is more like touch-typing. I personally could have beaten Chip and Ken 2:1 or better if I'd been there with a decent keyboard to enter the text, and I'm not a particularly good typist:

Another advantage morse has is that more-common characters have shorter symbols. At the extreme, an E is 1/19 as long as a 0(but only 1/9 as long as a 5 - an artifact of the system for numerics).
Few of these thoughts are my own. This was discussed to death on ham radio mailing lists, on the air, and in coffee shops nation-wide, 3 weeks ago.
My 8(-3.5)year 2.11GPA degree showed that eventually, I would put up with the bullshit and get the requirements completed. My career has no subject-related benefit from my Biology major/Chemistry minor Liberal Arts (A.B. (our diplomas were in Latin - that's a B.A. to all you Philistines)). I had the piece of paper and bullshitted my way into my first P/A position. Good work since then has resulted in kept me (mostly) gainfully-employed.
Beyond what it takes to graduate, take classes that interest you.
distributing the cost across the nodes of the tree
Just like on a CW net - the cost (about.000000001/char) is spread among the sender and all the receivers... except those damn freeloading solar-power users.
Cheaper than an equivalent Leatherman branded device, and it's a knife company. The blade (and other tools) lock securely and are made of VERY good steel. It holds a good edge for a very long time. 5 years now (second one - I lost the first).
That is also true. If you have not consented to the installation, you have no responsibility to preserve it for the use of the entity that placed it there, even if they had a warrant. Can you imagine someone getting an additional sentence for destroying government property for destroying a phone bug, for instance?
wd-40 his break pad
Isn't his "break pad" where he takes his breaks with the cute AA? It's probably so slippery with K-Y already that a little WD-40 wouldn't make any difference... now, some heavy grease on the brake pads on his car... that'd be something.
I really do. It's solid. It's flexible. It's convenient. It's really free. If you insist on it, you will fail. Get RedHat Enterprise Linux 3. Workstation will do. If you're going to knock their socks off with a proof of concept, use Fedora Core. That way they can see a clear relationship between what you're showing them and what they would accept in production. The RH stuff is good, AND, it provides the requirement for all serious businesses "Who can we call if something goes wrong, and who can we sue if it can't be fixed?". I don't like it. You don't like it. It's reality. Who knows? In a few years, once they're comfortable, maybe you can use the prestige you gain in this endeavour to do something purer.
I don't know whether you're ignorant enough to lump this with Cold Fusion to associate it with the fraud that it is, or you're implying that you think there's really something to the Adams Platform.
he probably wastes a bit of his focus and attention thinking
I've got to disagree. According to the parent, the box actually gives a warning noise when he manoevers too close to its defined envelope. Now, if he's pathetic enough to try to manoever around right against those limits all the time, yes, the box can add distraction.
If his dad confronts him about a brake dump followed by a 5-second burst of full throttle, and the kid explains getting cut off on the freeway followed by boosting like hell to get away from traffic coming up behind him unable to stop, he walks away scot-free, with no consequences beyond an "attaboy" for competent driving. On the other hand, if he has a 20 second dead stop followed by 20 seconds of full-throttle (I'm assuming somebody who'd buy a black box would be putting it in a wussy import), there's not a lot the kid can say in his defense. When he pays for his own car and insurance, he can take it up a notch (see my other post concerning brakes and ground contact).
breaks too hard I'm not sure exactly what you mean. You mean he himself breaks, or he breaks the car? I'd say either one is an indication of dangerous driving. If you break the car, or (heaven forbid) yourself, you're not doing it right. If you mean "breaks" in the sense of having one's trajectory affected by the bernouli effect from rapid rotation, I can sympathize as well, having done that myself, over a very short distance. Fortunately, the plowed and disked soil was dry, and let me do a sliding, spinning stop, instead of somersaults. Anyway, if you're flying through the air and spinning, that's right out, now isn't it? As old men in my hometown used to jokingly remind me, "The brakes only work on the ground, so try to keep it on the ground.".
Oh, you mean he "brakes too hard"? Why didn't you say so?
Don't get me wrong, rsync rulz. I haven't used it myself, but I've heard cwrsync solves the remaining problems.
Cygwin will do much more, though - apache, postgresql(probably mysql too, but I haven't seen it), etc. - almost any unix app you can get the source for, you can compile(and use) in Cygwin.
I keep getting in jobs that require the use of windows. I'm a unix guy. I retain my sanity by doing everything in cygwin. I'm wasting an exceed license right now because while they can require that I have it installed, I greatly prefer cygwin X and fvwm. I build most of my applications in shell or perl, sometimes with fakes of the unix apps they'll run against, to feed in the inputs or take the outputs.
Specifically, you say your product is mostly Perl and bash? You write in two of the most-portable languages of all, and you're worried? Jeez, man, it's RedHat! I assume you're using db::oracle or some such perl module for your fancy work. Your porting is likely to be no porting at all, i.e., you'll probably be able to scp your stuff in and just run it without further work. The ease of acquisition and configuration of the platform is such that determining details is honestly trivial. Install, run, try your apps, tell us what you find out.
I hung on for quite a while, in the hopes that they'd regain quality. Running it on a shit network like WB, though, made it impossible to keep up with it anyway. After 2 or three unannounced schedule changes, I stopped keeping up with it and started looking for the reruns to catch up, then stopped trying.
What is it about these networks, that they think it makes sense to run overtime with a game, then join a first-run episode of a series "already in progress", or if the game ends early, start the show early? These same morons who think "he caught the ball, and ran to the left, then he ran straight, then he ran left again" or "the next guy is going to try to hit the ball" is riveting, and no piece of it must be missed, think a story, with a plot arc, is like background music... filler that you just turn off and on and interrupt as needed.
I started to use "water faucet" instead of "background music", but that lead to "My pain belongs to the divine...". Yeah, when they lost Rev Bem, it just sort of deflated. He must have been reading ahead in the scripts.
beginning, middle, end. Beginning and end are discrete points. Middle fills the space between. Even the penultimate episode is part of the middle.
Oh, and unless I misunderstand the concept of "end", it appears that it has ended, therefore, by definition, the last episode is, in fact, the end.

Just remember to use that everywhere the word "me" should go (my personal pet peeve).
