The second TST day was worse than the first one.

There was a damn geometry-related problem which I couldn’t solve. I scored only 45/300. Totally, I have 140 points which isn’t enough for me to qualify to IOI and BOI.

Oh well, hope to do better next year.

I participated to the team selection test today where the BOI and IOI team should be selected. Unfortunatelly, due to a stupid mistake (declared integer type variables instead of longint and missed 105 points) I now only have 95 points.

There were three problems which were relatively easier then the IOI-type ones.

Tomorrow is the 2nd team selection test so I hope do better today.

P.S : I will never forget this longint-integer  stupidness.

I’m pretty sure many of you heard about the End of the world, which will occur on December 21st, 2012. We heard about reversion of magnet poles etc. The USA even bothered to write a press release related to this date.

From my point of view, here’s what it’s gonna happen:

- Earth’s magnetic poles will reverse, crushing millions of innocent GPS devices

- The well-known Mayan calendar is going to end which means…ye, Windows calendar will crash (again)

- A big fireball (similar to the Pyroblast from World of Warcraft, only 100000x bigger) will fall on earth, making all dinosaurs die (why does this remind me about something :S). Oh and you will die too

- Water will cost more then petrol since it will all evaporate because of the big bad fireball. Oh and as always, humanity will do something at wrong place at wrong time. Yes yes, until that, all the cars will run only on water so petrol will be basically useless! What a coincidence :S

- You won’t have internet because 21 is close to the end of month, and since you won’t be able to pay your internet (because everything will be destroyed) your internet will be closed.

I hope you take me in serious

I found an interesting article in Yahoo! (probably the only interesting article I found there) about the worst computer viruses ever existing. As we know, Yahoo! likes bull****** alot so I’ll just copy the virus name, the year discovered and a short description

Brain, 1986
It all started here: Brain was the first “real” virus ever discovered, back in 1986. Brain didn’t really hurt your PC, but it launched the malware industry with a bang and gave bad ideas to over 100,000 virus creators for the next 2 decades.

Michelangelo, 1991
The worst MS-DOS virus ever, Michelangelo attacked the boot sector of your hard drive and any floppy drive inserted into the computer, which caused the virus to spread rapidly. After spreading quietly for months, the virus “activated” on March 6, and promptly started destroying data on tens of thousands of computers.

Melissa, 1999
Technically a worm, Melissa (named after a stripper) collapsed entire email systems by causing computers to send mountains of messages to each other. The author of the virus was eventually caught and sentenced to 20 months in prison.

ILOVEYOU, 2000
This was notable for being one of the first viruses to trick users into opening a file, which in this case claimed to be a love letter sent to the recipient. In reality, the file was a VBS script that sent mountains of junk mail and deleted thousands of files. The results were terribly devastating- one estimate holds that 10 percent of all computers were affected, to a cost of $5.5 billion. It remains perhaps the worst worm of all time.

Code Red, 2001
An early “blended threat” attack, Code Red targeted Web servers instead of user machines, defacing websites and later launching denial-of-service attacks on a host of IP addresses, including those of the White House.

Nimda, 2001
Built on Code Red’s attack system of finding multiple avenues into machines (email, websites, network connections, and others), Nimda infected both Web servers and user machines. It found paths into computers so effectively that, 22 minutes after it was released, it became the Internet’s most widespread virus at the time.

Klez, 2001
An email virus, Klez pioneered spoofing the “From” field in email messages it sent, making it impossible to tell if Bill Gates did or did not really send you that information about getting free money.

Slammer, 2003
Another fast spreader, this worm infected about 75,000 systems in just 10 minutes, slowing the Internet to a crawl (much like Code Red) and shutting down thousands of websites.

MyDoom, 2004
Notable as the fastest-spreading email virus of all time, MyDoom infected computers so they would, in turn, send even more junk mail. In a strange twist, MyDoom was also used to attack the website of SCO Group, a very unpopular company that was suing other companies over its code being used in Linux distributions.

Storm, 2007
The worst recent virus, Storm spread via email spam with a fake attachment and ultimately infected up to 10 million computers, causing them to join its zombie botnet.
