My name is Álefe because it’s in Psalms 119 from the Portuguese version of the Holy Bible.

My birthday is 1/19, but nothing was planned with the 119 above.

There is a programming language named Alef (in the English version of Holy Bible my name is Alef), this programming language influenced another named Limbo, and this Limbo programming language influenced the Go, the Google programming language.

Álefe or Alef is the first letter of the Hebraic alphabet, and means “beginning”.

The dates on old Unix systems are based in 32 bits, when we reach the second 2147483647 (the final int 32 bits number) from 1 January 1970 will occur something like the Millennium Bug, this date will be 19 January 2038, my 41 years old birthday.
