AC will magnetize iron. With DC you can choose where North is. With AC North and South flips back and forth as the AC cycles through zero volts. When you turn off the AC, then the iron is magnetized in the last AC direction.
So to de-magnetize something, you need to put it into an AC field, then slowly pull it away. The magnetism will reduce as you get further away until it is effectivley nothing.
I forgot to mention that the LAN adim tested the backup each morning with a sample file restore. Which is why they thought that the backups were valid.
I heard a story about a LAN admin who was doing backups every night. The tapes would go into a safe, then would go offsite, then be used again.
Everything worked well(?) until they needed to do a restore. The tape in the safe was corrupt. The tape at the offsite storage was corrupt. No tape was good.
It seems that the LAN admin made tea every morning. The electric kettle sat on top of the steel safe.
So the backup tape was placed into the safe, then the kettle was started, magnetizing the safe, and erasing the tape.
Not ONCE did anyone try to do a test restore to prove the system.
Any IT person who says they will "never" upgrade, yet stay with Windows, is a crackpot.
Well then colour me crackpot.
I am about to buy my last Windows PC. It will be pre-loaded with XP. Once the service agreement runs out, and the hardware breaks, that is it for me and Windows.
Linux, ReactOS, MAC, or something, anything else.
And I am senior enough that the PHBs will not force Vista on me.
My Social Security card clearly states that it is for Tax and social security purposes only - not for identification. Yet every organization out there wants to use your SSN for an ID.
In Canada we have more-or-less the same wording for our Social Insurance Number (SIN). And the law has teeth. It is illegal to use the SIN for primary identification. The military had to re-vamp its own internal systems, as they started out using the SIN as a soldier's ID number. Now they generate some random number.
I refuse to give out my SIN to anyone who cannot prove to me they actually need it. If they say they will not give me a (membership | account | whatever) I simply leave.
The company could know more about web surfers than they know about themselves."
One the surfers who do not block these things.
What with AdBlock, selective blocking of cookies etc, my surfing habits are just about invisible. Only by tracking the IP address could anyone read my habits. But then, I am behind a NAT with many other people, so this is hardly reliable.
So what will happen (and probaly already has) is that the people who do not know any better will form the basis of what "surfers" do.
Much like a few people determine the TV ratings and so the really good shows go away. You know, the shows that require some modicum of intelligence to understand and appreciate.
At one point he rebooted from windows into OS/2 and executed a large copy (along with a few other things) in OS/2 and said: 'booting into OS/2 and doing this is a lot faster'.
I was using a DOS + Windows 3.11 machine, which had dual boot to OS2 v 3. We also had a Netware LAN. Close to me was a machine which was monitoring LAN traffic.
Doing a copy over the LAN using OS/2 used about 25% less LAN traffic than the same copy using DOS. I did tests before anyone else was using the LAN (this was an internal test LAN).
MS has always been less efficient in doing these mundane operations.
And copying one large file is much better than copying lots (1000+) of little files. In some cases I ZIP up the files, copy them, then unzip them (over a LAN/WAN).
Toggling in binary (from Hex cheat sheets) to get the CPU to the BIOS, so it could read enough to be able to read the tape drive which held the program to read the DASD to read the actual program.
This is yet to be determined. Until there are uptimes of over a year, you cannot say it has more stability. And more stabilty than what? I have seen Novell Netware machines with uptimes of over three years.
We had one Netware machine continue working after its drive fried (before the days of cheap RAID systems). We only found out because we were going to upgrade the RAM.
This switch to Windows servers is a step backwards.
Vista raises the bar on user interface
No, it just changes the way it works. I have not tried it so this is entirely form other posts and ads, but having little minature screens in some 3D effect showing me what is minimized is silly. Besides, I can get almost the same thing from the power tools. You ALT-TAB and you get little minature screens showing you what is minimized.
And as for the Office icon ribbons, yuk. I want to see and do what I want to do. I hate it when an application hides stuff from me. So yes, the first thing I do is turn off "personalized menus" in every MS app.
And I prefer WordPerfect to Word, mostly because I can have "reveal codes" show me exactly what markup codes are being used and where. Word just gets in my way. You turn something on, can't get rid of it, then wonder why your cursor and text are screwed up.
Do not forget Chicago, which turned into Windows 95.
MS was going to make a new OS from the ground up, completely object oriented, not DOS etc. Something like OS/2 but entirely from MS.
The first alpha releases were that, but then time lines stretched, marketing took over, and MS put a GUI layer over DOS, rolled out Windows 95, and said "Look at us, aren't we great!".
Plenty of people seem to think that the following is a valid argument: "There has to be a God, otherwise we would have no purpose and that's too depressing." And that dictates their entire thought process.
More like:
"Why did this <insert event here> happen to me. There must be a reason! It must be because <deity> <loves|hates> me. I must pray more to save myself!"
There are many people who cannot handle random chance as being the prime mover behind everything. Which is why the phrase "Oh God, why hast thou forsaken me?" exists.

Not at all an urban legend. Go to Tech Tales so see all the stupid things non-techy people do.
Over time, maybe the safe became magnetized. It probably was not a single event.
Never the less, backup tape testing should encompass the entire tape loop, from tape machine through offsite storage.
I forgot to mention that the LAN adim tested the backup each morning with a sample file restore. Which is why they thought that the backups were valid.
Moral? Test the entire backup loop.

Already there. Every four years, need it or not.
The hope that deprecated will never happen.

That quote is out of Space Balls (the movie).
Hmm, let's see:
- Cable MODEM - always on
- Hardware Firewall - always on
With a DHCP lease lasting 24 hours, I pretty well HAVE a static IP address.
Of course this is not good enough to run a business, but I have never had to change my FTP target address to get at my home machine.

Sure, and how much media coverage did it get?
One or two stories, and then back to celebrity tracking.
What SHOULD have happened was a long series of stories about the event and the consequences.
More like:
"Why did this <insert event here> happen to me. There must be a reason! It must be because <deity> <loves|hates> me. I must pray more to save myself!"

Well I set up a machine specifically for IE7 testing. This is on an Intranet that is isolated from everything.
After IE7 started it wanted to connect to the MSN site. I waited until it timed out, then set the start page to "about:blank".
The next time IE7 started, it again wanted to connect to MSN. In fact it ALWAYS wants to connect to MSN, regardless of the blank page setting.
Annoying as hell, and what is it reporting to Microsoft that is so important (to Microsoft)?
No program is foolproof, because fools are so ingenius....
Yes it is.
That would be OS/2's HPFS which had Extended Attributes.
All sorts of useless stuff was stored in there including file associations (ie: which program to use to read the file).
I believe that the MAC file system uses forks, which have similar functionality.
Well yes, but I have found that it does not work with all computer/keyboard/mouse combinations.
The keyboard I have has a DIN plug attached to a DIN->PS/2 converter.
