I work about 100 Yards from ISM's building (the folks responsible for the lost drive).
Some interesting things have been reported in the media around here. Some have said the data was encrypted, and that it was unlikely that anyone could get the data. If it was encrypted with anything recent, it would be near impossible to get the information off of it. If I were talking to the media and new it was encrypted
It was also mentioned that information was in a database, and the tables couldn't be linked very easily... but who really knows.
Now please correct me if I'm wrong here (I'd rather learn something), but the reason I really like PHP is the fact that I can turn it off and on in an html document, something you can't do with PERL (unless I'm wrong here).
I started playing with PHP and MySQL sometime ago, just to see what it was all about, and all I can say is wow. I've learned so much, and started doing some small contracts with PHP. Its so nice to be able to take a.html doc from a web developer, cut the dummy data out and add in a couple of PHP lines, and bang, the page is now live to the database!
Had both, staying with Cable

DSL Rising
·
· Score: 1
I've used both and swapped back and forth a few times. Originally, I went with cable about 6 years ago, but it wasn't reliable enough. Switched to DSL, reliability was great, but they started changing plans where multiple static IPs were too much, plus they frowned upon running servers (no filters or anything against it).
Switched back to cable. Mainly so I could run servers (web, mail, DNS, HLDS off and on). The local cable company here doesn't care if you run servers or not. In fact, the head techie at the cable company is the founder and president of the local LUG.
For reference I'm in Regina, Sask. The DSL here is actually amazing. Communities of less than 5000 have access to DSL which I think compared to the rest of the world is pretty damn good. And I'm not talking suburbs here, I'm talking communites that are hundreds of KM from the nearest major centre. Of course around here, the major centres are only 200,000 or so people.
Start off by explaining "FREE". Explain both free as in speach and free as in beer... though maybe not in those terms considering the age group.
I would stay away from an install of Linux, you could be there all week answering questions on it alone (What does this package do?). Also, stick with a distro you know, but point out all the others. Nothing worse than not knowing right away where that config file is.
Next up, make sure they're familiar with whatever editor you plan to use. Leave it open to use more complicated editors (vi) if they know it, but otherwise stick to simpler ones.
Give lots of handouts/links to sites with further information
Pick a few languages that you are very familiar with, be it PERL, PHP, C, etc.
Get some interesting projects for them to work on, be it a webpage, game, utility, etc
We have a similar two stage system as mentioned above. When the installers came by a year later for a test, they must have "forgotten" how they hooked it up. Before the sprinklers actually start spraying water, the breaker that runs the power to that room is automatically flipped. The UPS we purchased for the servers is also hooked up so it doesn't do a safe power down, it just powers down.
Well, they came in to do the test, everything but actually spraying water, and managed to flip the breaker. It was interesting to note, that only a few of the machines actually powered off. Some are on smaller single machine UPSs, so those stayed running. The most expensive piece of equipment in there, a Nortel Telephony Switch which handles 6 PRI lines (almost 150 ISDN lines) is on battery backup, and kept running.
All in all very little powered down. In the even of a real fire, we would have had sparks flying everywhere. What did management do when I mentioned this to them? That's right, nothing.
I was at our LUG's first annual Expo a week or so ago (www.losurs.org/expo) and Jim Elliot from IBM was there. He said they are still working on it, but trying to bring the price down. They had hoped to release it for this holiday season, but it won't happen. I think they're now targetting this time next year.
Do you have a link to the article you mentioned? My finace loves the show and I occasionaly watch with her. I have no doubt that a lot of people would be repainting or what not as soon as possible. However, I do have to admit that some of the ideas on that show are very good.
Or, you could learn to drive in the snow and not need a big gas guzzling 4x4 that really only helps you get moving. For most people it provides a false sense of security as a lot of people seem to think that a 4X4 will actually help you stop quicker.
I've driven in Canda winters (and we're talking the praries) for over 10 years. Guess what, its not that tough. The biggest mistake people make is never inducing a skid to practice what to do. Find a nice open, empty parking lot. Get up to 40 or 50 km/h, crank the wheel and step on the gas. Now that the car is spinning, stop it, and do so in a stright line. Its not actually that difficult, and once you've done it a few times it becomes second nature.
Okay, ignore friction for a moment, we'll come back to that.
The antigravity shield is going to require energy to create an area where there is no gravity, or gravity is reversed.
In this area you put an object, which will then rise up. You turn off the shield, and the object falls, and you capture that energy.
What I'm saying is the energy captured from the falling object will at the very most, be just enough to power the anti-gravity shield long enough to raise the object again.
Now, take into account friction.
If the anti-gravity shield has any moving parts, the amount of energy you got from the falling object will not be enough to lift the object again. Moving parts generate friction. Friction uses energy in the form of heat which is dissapated to the surrounding area. However, this energy (heat) is not used to lift the object again.
Lets try it with numbers (physics majors will probably want to correct some things here)
Lets say it takes 100J to life the object, and you are able to extract 99J of energy, the other 1J is lost to friction (most likely) in taking the energy from the falling object. Now, you're already short 1J to raise the object again. Then when running the anti-gravity shield, you're going to lose another 1J to friction in the shield generator. Down to 98J. How can you lift the object again, when you don't have enough energy?
Simply build a machine which lets things fall down under normal gravity, extracts the energy, then moves them back up under your shield. Voila! Instant, infinite amounts of energy. I have yet to see anti-gravity that doesn't have these sorts of problems.
Um, how to you plan to maintain your anit-gravity shield? Since it will probably require more energy to generate the shield than you get from dropping your object (due to friction most likely) it doesn't violate anything.
Predator obviously has the weapons, but I think this would an intersting battle anyways. Predator seems to have the advantage in the games, however, Predator's cloaking is useless against Alien, so it becomes interesting. Take away Predator's weapons, and Alien has the battle no problem. However, between the disc and spear, Alien is in for a tough fight.
Of course the best fighter would obviously be an Alien spawned from a Predator! Hmmm, wonder if I can copyright this idea...
I work in a 6 story building, and our telephony room happens to be on the 5th floor. The space immediately above is leased by another group.
I get a call from the folks on the 5th floor saying there's water coming out from under the door (they don't have access to the room). Being the onsite telephony person, I rush up wondering what the hell is going on. Sure enough, water has soaked the carpet around the door. Opening the door I see as much as 5cm (2in) of water sitting around the base of the switch and various servers connected to the switch. All in all, probably around $300K worth of equipment, and I don't dare go in, because there are power cords lying in the water. Finally get the power turned off, the water out, clean everything up. All in all, costed us a couple hundred dollars for some new cables, one monitor, and various odds and ends.
Apparently what happened was someone on the next floor up was in a bathroom, turned on a faucet and forgot about it. The water managed to move about 5m (15ft) down the hall before deciding to pour out into our telephony room!
What does this say about the Canadian Government (whom I work for) when I try to access the 'Reporters without borders' site and get a message from the firewall saying that this site is forbidden by a rating check. Well, wherever Canada fell on the list, better knock us down a spot or two.
I used to think that too, until I did some reading. If a hydrogen tank is punctured, the hydrogen gas rises so quickly that there is very little danger. Even if it does ignite, it will burn up, and has the advantage of not sticking to things like gasoline will do. Hydrogen will dilute with the atmosphere so quickly, there's less danger than a similar incident with gasoline powered vehicle.
I always thought the idea that every possible game of freecell was winnable. Check Game #-1 - yup negative one.

Open Source Studies

· Score: 2, Informative
I'm sure others can do a better job explaining, but I'll try...
There are so many working in the open source projects.. who pays them ? Is everything a volunteering work ????
A lot (most?) of OSS is volunteer work. However, some businesses do pay people to develop for open source. I know IBM does, and I'm sure there are others.
how do they manage to put in so much effort apart from their regular job at some commercial company ? what is the driving force ?? interests in programming ? or not satisfied with their regular job? or is it do something to STOP microsoft !! i am really not clear about this !!
Everyone's drive is different. The little bit of OSS development that I've done started out as, "Why hasn't anybody done this? Guess I'll do it myself.". However, it soon turned into wanting to give back something to the community that has given so much to me. Some people do dislike MS enough to work against them. Others do it just because they want to develop and their regular jobs don't satisfy that need.
how do they find time to do so much ?
Ask them. For me, I usually spend an hour or so after supper doing either contract work when it comes my way, or developing to learn. Personally, development has become something of a hobby. I hardly watch TV anymore, partly because I sit and fidget because I find TV boring, and when I fidget, I get nasty glares from my fiance.
* is the company they work for aware of the employee who is working for them spending so much time for some thing not useful to them !! (either during the work or after work !! )
Again, ask them. For everyone its different. For me, I had to fill out a conflict of intrest form when I started getting contract work to do in my spare time. I work for the Government so I had to say I wouldn't use work time/materials on these contracts (nothing about posting to slashdot though).
Take a sufficiently large amount of water, freeze it, put enough pressure on it, and the internal temperature will be somewhere around 4C (~39F).
So, on a planetary scale, you're pretty much guaranteed to have liquid water at some depth. Otherwise, we'd have a lot more ice in the oceans and lakes of this planet then we actually do.
Now admittedly, Pluto isn't pure H20, but having water, this effect will be true to one degree or another.
Had the same thing here. When I came in, the intranet web server was IRIX. They wanted to move away because of the HW support contracts being too expensive. I suggested going to an Intel platform (we had extra machines around that had plenty of power) running Linux. Same excuse, if you leave, who's going to support it? Well in a systems group of about 20 people, 3 others ran Linux servers at home.
And when you're only talking about FTP access for a few web developers and a simple Apache install (our Intranet doesn't use any scripting, all static HTML) its not difficult to maintain. Instead, we spent several hundreds on a Windows NT license, and just recently another $1500 on a 2000 Server license. Meanwhile, there have been several applications that I could have built in a couple of days using PHP/Perl and a database like our room booking software (over $1000) and a telephone directory (still using an Excel spreadsheet).
If security was Easy, it would be less secure. For something to be secure, it needs to be sufficiently different and obscure to prevent 95% of all attacks
That sounds suspiciously like security through obscurity, which we all know *DOES NOT WORK*.
I've done some web apps that require a login, either to the standard/etc/password (/etc/shadow) or to a database of some sort. Sure I could make it very obscure, but if instead of validating that username and password everytime a page loads and instead passing a variable saying LOGGED_IN="TRUE", I defeat my own security by making it vary easy to bypass my login.
As the article says, validating input, and failing securely are two of the most important things you can do. If you're expecting a phone number, don't accept anything except numbers (and possibly -) as input. And make sure that if the system fails, it doesn't leave you wide open, it actually shuts down.
