The Most Secure Way To Delete your Data On Your HDD

April 16, 2009

My earlier post pointed to a method to recover some of your data from your dead hard disk drive. Now, I have found a way to do just the opposite, annhilate every bit of information that ever existed on your hard disk (and along with it the HDD itself)

An article on the MIT website (http://web.mit.edu/newsoffice/2003/diskdrives.html) pointed out how vulnerable your deleted data is for recovery.

Consider this ” Scavenging through the data inadvertently left on 158 used disk drives, the students at MIT’s Laboratory for Computer Science found more than 5,000 credit card numbers, detailed personal and corporate financial records, numerous medical records, gigabytes of personal email and pornography. ”

These HDs were bought from eBay for less than $1000.

This and one of the most sophisticated techniques as explained at http://www.cs.auckland.ac.nz/~pgut001/pubs/secure_del.html can make you almost paranoid about the security of your data.

So, here is a grand method explained here.

Its simple, just melt the hardisk down! This will destroy the shape and the HD itself, also it will destroy all its magnetic properties.

Good luck to anyone who wants to recover credit card numbers from this!

Light Saber Farm

April 12, 2009

Now this is when physics meets new-age art. Richard Box from physics department at Bristol University has planted fluorescent tubes in a farm that give out light due to the electricity leaked by the high tension wires overhead. This project has been named FIELD.

1301 fluorescent tubes illuminated in an English farm due to the high tension wires overhead. The illumination is because of the electricty that "overflows" out of the wires

The high-tension wires are at about 400KV and because the earth is at ground, an electric field is set up between the two. This excites the mercury atoms in the tube and in turn makes the phosphor coating emit light.

The electric field excites Hg atoms, The excited mercury atoms emit UV rays which upon striking the phosphorous coating makes it glow.

Tesla had been working on similar ideas in his last days – wireless transfer of electricity. Altough, Richard Box’s idea is not new (ranchers in mid-west USA are known to use this technique), Box brought it to attention because of his artistic rendition.

This just goes to show how much we lag behind in the handling of electricity. But it did help Box to set up such a marvellous farm.

Here’s to the Crazy Ones

Here’s to the crazy ones.
The misfits. The rebels.
The troublemakers. The round
pegs in the square holes – the
ones who see things differently.
They’re not fond of rules and
they have no respect for
the status quo. You can praise
them, disagree with them,
quote them, disbelieve them,
glorify or vilify them.
About the only thing that you
can’t do is ignore them.
Because they change things.

– Jack Kerouac
quoted in an Apple Computer Ad, 1997

Play those good old MS-DOS games again

April 6, 2009

This page here takes you back to those times when Duke Nukem’s 10 size foot ruled. If you are wondering what I’m talking about then maybe this site is not for you. It hosts many games of the forgotten era of MS-DOS, and you can play them online. Ah, those were the days!

Graduation Speech to Live By

March 11, 2009

Written by Mary Schmich

Ladies and gentlemen of the class of ’97:

Wear sunscreen. If I could offer you only one tip for the future, sunscreen would be it. The long-term benefits of sunscreen have been proved by scientists, whereas the rest of my advice has no basis more reliable than my own meandering experience. I will dispense this advice now.

Enjoy the power and beauty of your youth. Oh, never mind. You will not understand the power and beauty of your youth until they’ve faded. But trust me, in 20 years, you’ll look back at photos of yourself and recall in a way you can’t grasp now how much possibility lay before you and how fabulous you really looked. You are not as fat as you imagine.

Don’t worry about the future. Or worry, but known that worrying is as effective as trying to solve an algebra equation by chewing bubble gum. The real troubles in your life are apt to be things that never crossed your worried mind, the kind that blindside you at 4 pm on some idle Tuesday.

Do one thing every day that scares you.

Sing.

Don’t be reckless with other people’s hearts. Don’t put up with people who are reckless with yours.

Floss.

Don’t waste your time on jealousy. Sometimes you’re ahead, sometimes you’re behind. The race is long and, in the end, it’s only with yourself.

Remember compliments you receive. Forget the insults. If you succeed in doing this, tell me how.

Keep your old love letters. Throw away your old bank statements.

Stretch.

Don’t feel guilty if you don’t know what you want to do with your life. The most interesting people I know didn’t know at 22 what they wanted to do with their lives. Some of the most interesting 40-year-olds I know still don’t.

Get plenty of calcium. Be kind to your knees. You’ll miss them when they’re gone.

Maybe you’ll marry, maybe you won’t. Maybe you’ll have children, maybe you won’t. Maybe you’ll divorce at 40, maybe you’ll dance the funky chicken on your 75th wedding anniversary. Whatever you do, don’t congratulate yourself too much, or berate yourself either. You choices are half chance. So are everybody else’s.

Enjoy your body. Use it every way you can. Don’t be afraid of it or of what other people think of it. It’s the greatest instrument you’ll ever own.

Dance, even if you have nowhere to do it but your living room.

Read the directions, even if you don’t follow them.

Do not read beauty magazines. They will only make you feel ugly.

Get to know your parents. You never know when they’ll be gone for good.

Be nice to your siblings. They’re your best link to your past and the people most likely to stick with you in the future.

Understand that friends come and go, but with a precious few you should hold on. WOrk hard to bridge the gaps in geography and lifestyle, because the older you get, the more you need the people who knew you when you were young.

Live in New York City once, but leave before it makes you hard.

Live in Northern California once, but leave before it makes you soft.

Travel.

Accept certain inalienable truths: Prices will rise. Politicians will philander. You, too, will get old. And when you do, you’ll fantasize that when you were young, prices were reasonable, politicians were noble, and children respected their elders.

Respect your elders.

Don’t expect anyone else to support you. Maybe you have a trust fund. Maybe you’ll have a wealthy spouse. But you never know when either one might run out.

Don’t mess too much with your hair or by the time you’re 40 it will look 85.

Be careful whose advice you buy, but be patient with those who supply it. Advice is a form of nostalgia. Dispensing it is a way of fishing the past from the disposal, wiping it off, painting over the ugly parts, and recycling it for more than it’s worth.

But trust me on the sunscreen.
