Best use of PlayStation 3
Filed Under Linux, news | Leave a Comment
Recently scientists discovered the power of Sony PlayStation 3.
But not to play games, but to crunch numbers.
Gravity project utilizes 8 PS 3 running Linux – connected in cluster to replace 200 Supercomputer nodes.
Overall, a single PS3 performs better than the highest-end desktops available and compares to as many as 25 nodes of an IBM Blue Gene supercomputer. And there is still tremendous scope left for extracting more performance through further optimization.
This “mini” supercomputer is used to help measure these theoretical gravity waves – ripples in space-time that travel at the speed of light that Einstein’s Theory of Relativity predicted would emerge when such an event takes place.

Does it worth repairing?
Filed Under Uncategorized | Leave a Comment
From my personal experience it does not worth to repair some electronics:
1. Computers
– Even when repairing it goes by blocks. So if your computer is 2-3 years old you may try replacing defective part (most of computers come with 1-2 years of guarantee). For computers 3 years and older simply buy new one and restore your data from recent backup (You are doing BACKUP, right).
2. MP3 players
– they became so cheap that it does not worth it.
3. DVD players
– same as 2. they are cheap and HD/Blu-ray is coming.
4. Cell phones
– Here the same principle rules.
5. Microwaves
– impossible(and really dangerous) to repair by yourself and better just buy new one.
Those are most common…
But this principle works also for many other things.
For example to clean a carpet (most common ones)Â you need to spend around $30 to borrow carpet cleaning machine but new carper will cost you $50-60.
Does it worth it?

MS Excel 2007 multiplication bug
Filed Under error, Windows | Leave a Comment
Multiplication bug in Microsoft Excel 2007 has been reported to Microsoft.
How to verify if your Spreadsheet has the same problem?
Simply put =850*77.1 in any cell the correct result is 65,535, but MS Excel 2007 calculated it as 100000.
There are several other “buggy”combinations reported by other users:
What’s even stranger is this: Â Suppose the formula is in A1.
=A1+1 returns 100001, which appears to show the formula is in fact 100000
and a very Serious problem.
And if you multiply be say, 2 you get something else:
=A1*2
returns 131070, as if A1 had 65535. (which it should have been)
=A1*1
Keeps it at 100000.
=A1-1 returns 65534
=A1/1 is still 100000
=A1/2 returns 32767.5
Using MAX() on a range appears not to see 100000.

New way of printing on CD/DVDs
Filed Under news | Leave a Comment
If a CD is round why we need to print on it as it was page of paper?
This was (probably) the question DYMO engineers were asked and they developed new way of printing on CD – just spin the media and print on it
The result is:
With this product they introduce new measuring format dpi/min and their firs product is intended to have 600 dpi/min which means 1 cd per 60 sec.
Expected price tag is: ~$280
One cartridge will last 100 CDs.
