40/2012 Vedic Maths ? Beware !

Vedic maths ! Beware !
I came across this incredible advert which claims that your child will become a "maths genius" if you put him in the course on Vedic mathematics which the advertiser was organising.

Don't fall into the trap.

Read the facts about vedic maths, and then take your own decision ::


There are much better ways to make your child a genius in maths.


PS :: Some questions to the advertiser. .

1. When do you call a child a "maths genius" (your own words) ? How do you confirm this ? By what measurements ?.

2. How many of the teachers of this course can themselves be qualified as "maths genius" ? Would they be ready to face a public jury of qualified mathematicians ?


39/2012 Rogue DNS malware --courtesy MSWin32

See my earlier post :: 31/2012 A new threat to the world

What is the point arresting those who created this malware. Why not shoot all the criminals who are responsible for this epidemic ? Start with the perpetrator MSWin32 who makes it easy for such crime to be committed again and again and again. Start with all the dumb asses who help MSWin32 by using the scum bag MSWin32. (Are you one of them ?)

If you are a victim or are wondering if you are a potential victim, take a look at::https://forms.fbi.gov/check-to-see-if-your-computer-is-using-rogue-DNS

Better still, just stop using Win32 and switch over to safer alternatives. Dont let your irresponsible and recklesses choices cause a disaster to innocent users of the w-w-web.

I wonder why. I wonder why.
I wonder why I wonder.
I wonder *why* I wonder why
I wonder why I wonder!

A tantalising way to teach/learn discrete mathematics (application of graph theory)

Ever wondered how a bunch of four (painted) wooden cubes can teach you discrete maths ?

Try the puzzle called "Instant insanity".

If you dont know about this puzzle, read::


And, if you cant figure out how to solve it, read ::
