On September 11, 2009,
then president of Russia Dmitry Medvedevsigned
the decree to make Day of the Programmer an official holiday
Programmers’ Day is celebrated on the 256th (hexadecimal 100th, or the 28th) day of each year.

“Writing the first 90 percent of a computer program
takes 90 percent of the time.
The remaining ten percent
also takes 90 percent of the time
and the final touches also take 90 percent of the time.” (N.J. Rubenking)
