This would provide a surprisingly simple way to build an electronic keyboard with weighted keys to feel like piano keys, and a pressure sensitive sensor so that they *play like piano keys.
From the description it should be much more sensitive than piezoelectrics. Think about it, have an actual felt hammer hit something. Say a short length of taut nylong cord. Except you've got some of this material stretched over the hammer. You could build the whole mechanism as though it were a piano, but without the bulk of all that goes into the piano to actually make noise.
This should be a lot more responsive than keys that are merely velocity sensitive.
He's got some interesting theories. Most of them are crap, but I can forgive that. What confuses me is this statement:
"IT has a culture of its own, and it's a culture that's usually detrimental to keeping workers happy," Cappelli says. "It's amazing that IT management practices simply run counter to how human resources people feel employees in all other kinds of jobs should be managed. Organizations should apply basic management principles to keep IT people satisfied and engaged in their jobs."
Now, I know we have our own culture. But beyond that first statement, it's all very vague.
He seems to be implying that the demands of our culture result in us disliking our jobs. How does THAT follow? I need some specific examples, but hee doesn't offer anything.
He seems to be saying that the best way to keep IT employees is to treat them like assembly line workers. I don't get it. I'd never accept a position at such a company, so they'd have a hard time retaining me.
Furthermore, companies with deeply entrenched corporate culture like IBM are having an awfully hard time retaining young IT workers. And they see the problem as being specifically because IBM culture isn't a good substitute for the usual IT culture.
So is this guy talking out of his backside or what? Like I said, I want examples and reasoning, not just an opinion.

Read the post replying to the post above yours. Humanity is defined by what we can and can't do, and these parameters are what shape our consciouss and unconsciouss minds in the way we call "humanity". By altering these parameters we alter how we think, and thus become something other than human.
My fault for not reading all your drivel, but I disagree. I don't think that defines humanity. I also think that even if it did, anything we do to alter our own course can't possibly be argued as diverging from humanity.
Moreover, hasn't this been going on since the discovery of cannibis? Probably further back than that. People have been entering altered states of conciousness through asphyxiation, starvation, meditation, and whatever else they can do to adjust their alpha waves since well before biblical times.
That we continue to advance without trying to throw away that which we are and that which has gotten us this far? Not too much to ask IMHO.
I think it's foolish to assume that anything is being thrown away. It's being built upon.
You heard me. You're just a slightly more up to date version of the folks who speak out against ATM machines, electro-magnetic radiation from home appliances, and the Evil Internet, yet accept technologies like refrigeration and internal combustion engines, because we've had that technology "forever".
Why is it so common to predict the end of the world (what do you think Escatology is about?) based on a pretty graph that shows steadily increasing technology?
How do you define this "Humanity" that you propose we are abandoning in favor of technology? How, exactly, are we going to go about abandoning it?
What humanity is doesn't change, and hasn't changed. We are still the same race, with the same problems, the same hopes, and the same daily social trials as humanity had one thousand years ago.
You people love to propose that as a whole we are less than we were because we can do something differently. I say we are not.
Security guards have reportedly been confiscating cocacola products. It seems Pepsi is the official soft drink of the 2000 olympics, and someone thinks "official" ought to mean "the only thing allowed".
Also, a food vendor that was selling an item with egg and ham was booted because it sounded too much like an egg mc muffin.
The IOC is getting way out of hand. I live in Utah, so I've heard all the bad there is to hear about the SLOC-IOC scandals. I'm embarrased that we even wanted the winter olympics here. I'm planning to be on vacation out of state when they happen.
No, they were really cracked. I've seen the data. It was posted to a publically accessable web server for quite some time.

Try running the software instead of judging it just from the author's rants. djbdns fully supports CNAME records. DJB simply does not provide a command line utility for adding them, like it does for A, NS and MX records. Big deal. The utilities are provided as a quick-start for newcomers. There are some other esoteric BIND features missing from djbdns, but simplicity is one of djbdns' features. It was never meant to be a replacement for BIND, so criticizing it for not being a drop-in misses the point.
Alright, my bad. I sure thought i had read somewhere that it simply couldn't serve them up.
That's OK tho. There are plenty of other things wrong with djb software. like the licensing, and the attitude.
OK, I'm sorry. I shouldn't talk down to people, but that "cloaking debian" article, while definately helpful, smacked of an amateurish failure to fully comprehend how these things work. For starters he has you turn on ip forwarding w/o even mentioning what it's for and letting you decide if you really want it. (tip, unless your linux box is a router, you don't)
Run it. Read it. Study it. Compare it with the documentation. OK, just use it, but using it and working with it can help you get a far better grip on what's going on. The script it will generate for you is FAR better at keeping a lid on your network connection.
He *Says* it's never been broken into. qmail has been a vehicle for attacks in the past, he covers this by stating that it was a bug in the operating system that made it possible. Sure, whatever.
I respect his abilities, but he's unfortunately off his nut. That's the problem with fanatics, generally.
I've been disappointed with the quality of CMOS image sensors compared to CCD. They seem to be slower, produce somewhat distorted images, etc. Maybe it's just new technology, but I'd like to see sample untouched photos of moving objects outdoors.
What a lot of people are ignoring when they cite this definition is that making such a device available is explicitly *Not actionable. And i quote:
Sec. 1008. Prohibition on certain infringement actions
No action may be brought under this title alleging infringement of copyright based on the manufacture, importation, or distribution of a digital audio recording device, a digital audio recording medium, an analog recording device, or an analog recording medium, or based on the noncommercial use by a consumer of such a device or medium for making digital musical recordings or analog musical recordings.
The ammount of corporate buyin among radioshack store managment varies quite a bit. Tandy has a long history of abusing them.
Mostly it goes back to the way they reeled in their privately owned franchises. The way it used to work, every year the franchise owner had to fill out a silly form and send it to Tandy, and every year Tandy would send back a form letter letting them know they're still a franchise.
Then one year, an aquaintences father, who owned a 'shack franchise, sends his form in, and gets back a letter saying something like "your franchise has not been renewed, here is a check for your original investment. While ownership of this store has been shifted back to Tandy corporation you will be allowed to keep your position as manager at a salary of $26,000 per year" - of course, that investment was made in the early 70's and no account was made for interest, increased value of the property, inflation, etc. 20 years and they basically told him to take his ball and go home.
So he contacts some other private franchise owners, finds out they all got the same letter and check. At this point, they figure they're screwed out of their businesses but not out of the actual value of their stores, and contact a lawyer to see if they can sue Tandy for the increased value of the stores.
The lawyer does some research, finds out this was nation wide. In one fell swoop, Tandy shut down every privately owned 'shack in the nation and gave every one of them the shaft. This becomes a class action lawsuit. Other greivances are brought up.
For instance, the franchise agreement stated that Tandy would aquire the merchandise and then sell it to the franchise at 10% over wholesale cost. Many franchise owners suspected over the years that they were not getting this deal, but hadn't rocked the boat. Some investigation was done, and several of Tandy's asian suppliers were identified. Many of these suppliers were contacted and told that a group of investors was considering starting a chain of electronics stores, and was seeking sample merchandise and quantity pricing for a list of items. The suppliers responded with an exaustive price list and sample merchandise.
The sample merchandise proved to be identical to radioshack merchandise, and the price list showed that the wholesale cost of the items was far below what Tandy had represented. Indeed, some popular items were being marked up as much as 600% before being sold to the franchises.
In the end, Tandy lost. Big. In excess of one million dollars per franchise.
It would be safe to say that i have no love for Tandy or the shack. It would also be safe to say that this is a corporation that doesn't engender much loyalty in their lower management.
What's more, two out of the three I've got were handed to me by teenagers, who obviously don't care. There are five shacks within 10 minutes of home and they keep separate customer databases.
The way i see it, this will probably really only take the gloves off in the KDE vs Gnome battles.
I mean, these folks bicker constantly. Do you honestly thing that having compatible licenses will make everything better? Heck, I half expect to see a statement from debian to the effect of "We're still not going to package your desktop, because we just don't like you, Nyah!"
Personally, I'm riding the fence on this one. Hate the gnome panel, hate KDE's separate panel and taskbar, hate the look & feel of QT apps anyhow. I haven't seen a desktop environment since OS/2's Workplace Shell with StarDock's Object Desktop addon that i really liked, so I'm using IceWM with no file manager and no silly icons all over the screen. (For the record, Ice's toolbar looks like Lotus SmartCenter, and Win9x looks like SmartCenter)
But he said it was five years of hard work by *geeks*. base64+xor67 is pretty freakin easy.
It's hard to even call this reverse engineering. The first software that came out was the result of people scanning many barcodes and comparing the output on the screen to the numbers printed under the code, and then doing a simple deductive analysis. It was only after that that someone realized the encoding scheme was a very simple sort of conversion.
There's a simple reason you don't often see copper heatsinks - copper is a heck of a lot more expensive than aluminum.
Thus, a company that wants to price competitively will design a casing that will allow the larger aluminum heatsink to save a few bucks over using copper.
I imagine that copper or more exotic materials are used pretty often in tight spaces like notebooks tho.
There's *Got* to be a better reference on security with bluetooth devices than that web page.
Basically, the guy says "Oo! Radio waves! Anyone with a paperclip and a sheet of aluminum foil can listen to radio waves! The sky is falling! And i don't know *ANYTHING* more about it!"
The problem of securing data that will be heard by unwanted recipients is very, very old. It may surprise you to learn that your connection is no more secure through an ethernet hub than it is over a bluetooth link.
Or honestly, any information that's transmitted over the internet. Traceroute to something. Every host it lists between here and there can snoop your connection.
The problem is not in the encryption per se, but how it exchanges keys. This can be fixed.
Sure, no data transmission protocol is ever truly 100% secure. But there's "somebody maybe might find a way to get the inverse of my public key" and then there's "Any scriptkiddie can flip their device into promiscuous mode and have all the data fly into their lap."
A lot of people argue that mediocre encryption systems give people a false sense of security. In a mission critical operation, this is true, you shouldn't trust it just because it's not cleartext. But for me, for personal use and casual corporate use, I'll take any system that's difficult to snoop over any other system that's flat out easy to snoop. Wouldn't you?
I thought this was going to have something to do with the shell, ash, maybe it's time for me to go schedule some vacation time, somewhere without electricity . . . .
That's not possible. The FTP protocol doesn't include any name information. The FTP server doesn't know what host you think you're connecting to, it just knows it recieved a connection to a particular IP.
Name-based virtual hosts work because an HTTP 1.1 request includes the hostname. FTP requests don't. It's as simple as that.
Chances are your isp is doing something like I used to have to do, with the ftp server CNAME'd to the web server, and the web server ip based. The reverse works just as well but looks silly.
Most people running a web site don't actually need an ftp server for the public tho, and just use ftp to upload their web page. In that case, they should definately be using name-based virtual hosting, and the isp should be up front and honest and not even bother to tell them they can ftp to their "web server" and just tell them to ftp to web-farm.isp.com or whatever.
The business model this is going to kill is the one wherein the service gives the customer a whole virtual machine. That *Definately* requires an ip per customer.
Except all I need is a pickpocket and a photocopier to break into your system. Maybe just a good camera and photoshop.
password protected systems can include things like panic passwords - special password you give out when someone has a gun to your head, that works, but sets off alarms, destroys or encrypts sensitive data, etc.
Carrying around the code to get into something is just silly.

Well, it's a PCI bus on a Cardbus card. Regular pcmcia / pccard won't cut it.
.c0m and .n3t should do it :)

He's a great programmer, shame the elevator doesn't go all the way to the top.
Maybe it has an .avi extension because its in AVI format? Maybe?
.asf and .mpg files should also be .AVI, since they fit the same description. As should .MOV for that matter.
AVI isn't so much a format as it is a blanket description. Stands for Audio/Video Interleaved.
Given that,
Truth be told there are about a dozen proprietary codecs that you may find in an AVI file.
OK, I'll admit that there's probably a standard header to help your application find the codec. But it's still annoying.
