I read years ago (and I'm sure it was made up) of a memo sent out to IT managers in the DOD (United States Department Of Defense). It went.
To properly dispose of hard drives which may contain Top secret information is a 5 step process to be performed in the order specified and by competent engineers.
1. Perform a triple overwrite security erase on the entire disk.
2. Use a bulk degausser (AKA a powerful electro magnet).
3. Crush the drive under a roller or tank tracks, whichever is more convenient.
4. Melt the scrap into slag.
5. Bury that Slag in a toxic waste dump to deter any attempts at data recovery.
That's not exactly how it went but I think this is pretty close. Can anyone find the original?
Could you clarify please? I thought this is why you can buy panels with a rack that tilts to follow the sun. Install such a system in a dessert (like Nevada) and you should get quite a bit of power.
But again. I am just trying to gather information so please explain why this is wrong. (As under informed speculation usually is.)
I remember reading that it takes more energy to build a Solar power system than that system will deliver in it's expected lifespan.
Is this true? If so is it true of all Solar power technologies or just some? Or is it a mild exaggeration like the Humer impacting the environment less than a Prios?
After reading the linked commentary, I can say there really is a better 4th option. It was even hinted at by the author.
Write your extension/hack as a modification of Rails and/or Ruby. Send them back to the maintainers of said products and see if you can get them inserted as a standard part.
If they do not exact a significant penalty elsewhere for the improved performance in your pretty mundane scenario. It is highly probeble, your changes will be accepted.
This isn't just true for Rails. It's true for any software (except stuff maintained by immature, anal retentive morons.
If it's L/GPL, BSD or other common free license, then this adoption of customer written code is a routine matter. If it's closed source and proprietary they may feel the need to get a lawyer involved and have you sign over all ownership rights to the code you wrote to improve their product (ask for money or stock when that happens).
Either way, in most scenarios good clean extensions tend to get adopted as part of the main program.
PS: Yes. Even "The Evil Empire" (Microsoft, Sun, Apple, IBM etc...) have been known to do this.
IANAL but I hang out with them and have run a network or two.
Actually this guy's best bet is to start collecting the purchase price from the students immediately. It dosn't matter how much. If you take $1 per month as higher purchase or even rental on these machines then you are not responsible for the misuse of them. Even illegal use.
If you do that then you can just filter P2P on the school network and log web traffic with a view to just warn those you spot wasting a lot of time on porn or social networking sites like Facebook and SlashDot (duck).
How many times per day you can have sex is heavily dependent on how you define "sex".
I remember President Clinton at one point narrowing the definition to exclude what he did with Monica Lewinsky, but dose that really hold true for all of us or just men in the white house?
The real downside is that women who live togather tend to have synchronised menstral cicles. Imagine your pain on that one weekend off when you get home to find 5 wives and nobody to screw.
Or worse. 5 wives with PMS all bent on "discussing" your failures with you.
I live in a country that denies it's citizens this right and guess what?
IT DOSE NOT WORK !
We have roughly 8 times the murder rate you Americans do, even though our people are no more ignorant or violent.
Violent crime (Especially murder and Rape) are primarily about power. Once the government creates an artificial power disparity between the law abiding and the criminal, those criminals will become more active and the rest of society will suffer.
The 2nd amendment is the only thing keeping America's crime rate close to that in other developed countries. The joke of it is that you Americans have to talk about this all the time and form organizations to maintain the status quo while other people just shut up and buy the tools they need with nary a peep from anyone. Canada and Switzerland come to mind.
I don't know. They are welcome to collect my previous bodily fluids for a small fee.
Back on topic: The US Military couldn't find that lost nuke because I already salvaged it and will use the components to build something far more dangerous than a conventional nuclear bomb.
With this device I will have leaders the world over cower in abject terror as I take command of the world throgh them.
Hmm... Funny thing is, when I check my SlashDot user page, the only comments from me that are ever modded down are about atheism.
Slashdot mods are willing to asses the merits of even a closed source argument or laugh at a Pro Republican joke, but give them anything involving Religion or Evolution and you get the instant knee jerk.
Since I work for a company which sells a Wireless broadband service I can confirm that WiFi is not "Wireless Broadband" just like Ethernet is not wired Broadband.
Wifi where it is available is a LAN. If you connect to Wifi at a coffee shop, travel 100 Meters then connect at a fast food joint, you are moving from one LAN to another. How those WiFi LANs connect to the internet is likely a Wireless or Wired Broadband service.
A scientist / clergyman argues that creation should be discussed in science class and 'scientists' want him fired or this?
WTF?
What ever happened to letting the facts prove themselves?
What ever happened to the notion that your scientific theories are better because they match the available evidence more closely than anything else available?
Now we have scientists trying to silence a dissenting opinion? You guys are starting to sound like the geniuses who after proving that the Earth was flat set out to imprison and torture those heretics who argued otherwise.
This attitude makes me more weary of Evolution than of any other scientific theory. no matter how may ways people try to argue ague against gravity or electricity, they are simply confronted with the evidence or simply ignored.
Only Biologists try to get heretics fired or simply silenced in defense of the sacred Evolution dogma.
This is wrong!
You should all be ashamed of yourselves for not seeing why.
Seriously though, I wonder if this genetic defect correlates with any genetic traits that make kids more likely to enter politics?
I.e. Just like Dyslexic persons are usually able to see patterns and correlations that mis others, perhaps these none learners have that extra arrogance which says "a million strangers will choose me over you".
In the movie everyone will be discussing below, several proposals were bandied about to use gentler methods to move the asteroid.
The problem with every method but nukes was that they worked too slowly to be of use when the asteroid is already close and just days from impact.
If we can plot the course of an asteroid and discover years in advance that it's going to hit us, a tiny rocket mounted on the surface and fired at an angle would be enough to solve the problem. The difficulty is with calculating the trajectory far in advance because every other object who's gravitational field extends into the asteroid's path changes that path.
So for anything but nukes to help us, we would have to track not just the object likely to hit us but every object that it could come close to between now and the date of impact.
I'm building a hosted Email service and one of the things our clients demand is that we be able to keep all email (including the deleted ones) for 7 YEARS.
They site regulatory compliance issues and corporate governance rules that were changed after the whole Enron, Worldcom series of fiascoes.
So what your company and the original questioner's company are doing is illegal in some places. Jamaica only imitated America on this as far as I know but feel free to enlighten me.
Last night we had a power outage. I shut down the desktop and was able to continue working for almost 2 hours on the laptop because with the Desktop down the UPS was only carrying the DSL router and the WiFi box.
At work. Power is a whole enterprise within the company I work for.
Dual gas powered Generators at each location, Rooms full of Batteries for the Telecoms gear (most is straight DC) and Inverters for the Servers. (DC PSUs are available for some of the servers we use but at so high a premium that the inverters are cheaper.)
We can handle a dozen Power cuts in a day with no service interruption or data loss ("Tested" 2 weeks ago) and we can stay up without external power for more than a week. After that we have to start trucking in additional diesel.
Yep. That's right. With sufficient fuel we can be online indefinably. Which we will have to do if we get hit by a major hurricane.
Which means the phone network is a lot more reliable than the Power grid where I live.
As for Data loss. I have over the years done a lot of recovery work. "Morfy" of "Murfy's Law" fame isn't a guy or a girl. He is a deamon from the darkest pits of hell sent to torment the souls of IT workers everywhere.
Imagine a server, where UPS #2 is down for repairs, UPS #1 fails during a power cut, When everything comes back up we find 2 failed hard drives in the RAID 5 on the email server.
despite previous testing and confirmation that the backups work the most recent tapes failed to read.
Eventually we sent the failed drives off to a Data recovery company in Florida because
#1. The customer can afford it. #2. Simply "skipping" a few days of Email is not an option for a bank (hence the ability to afford data recovery).
So yeah. A UPS is essential. Just like RAID, Clustering and Backups but in the end it can all fail.
Best advise? Memorize all your important data. That way if you loose your mind, you are not responsible for the lost Data (or anything else).
The Radar units used by the police here work just fine. They have been tested at the Auto racetrack. The cop was lying. Which is why he abandoned the idea of ticketing me when I pointed out the gap in his statement.
As to why he would do that. It's called inviting a bribe. I was supposed to offer him some money to let me off the hook. It's a simple enough scam and cops can really enhance their incomes with it.
Another busted stereotype. Ever notice in movies how cops are threatened with traffic duty? As if that is a punishment, or a place for failed detectives?
Well around here, the traffic division has to turn down a ton of applications each year.
Not only that but you would be shocked at the assignment cops have to be forced into. Protective services. I.e. The guys assigned to protect Judges and Government Ministers. They get "appropriate cloths" (read nice suites) at government expense. They eat at government expense while on duty. They travel overseas as part of normal operations. Usually at the nice places where Ministers meet with visiting officials and best of all the people under protection are not really targets the way an American President is a target (how many have you guys attempted to assassinate?)
However they don't get to collect any bribes or skim anything off recovered assets.

Maybe they subscribe to something like the "Prime Directive". I.e. The real idea is to observe Earth life secretly and learn what they can.
Then they had an accident and in order to avoid discovery by intelligent life, they crash landed in America.
With that in mind which part of America would be the best choice for such avoidance? Why a Military base in the mid western desert areas.

This was on a Highway.
Except for the toll road which was constructed after that incident 80 Kph is the highest speed allowed on Jamaican roads (Toll road allows 110 Kph).
It was years ago. I would have been out by now :)
