#Euklidův algoritmus

Začnu tedy tím, co jsem se dočetla zajímavýho. 📖 Euklidův algoritmus byl napsán už asi 300 let př. n. l. a to panem matematikem Euklidem v knize Základy. Používá se pro výpočet největšího společného dělitele (greatest common divisor) přirozených čísel. Existuje taky Rozšířený Euklidův algoritmus, ale o tom zas jindy. Teď už matematika!

Příklad: Mám číslo 21 a 12

krok: 21 / 12 = 1 , zbyde 9

Cryptographic Best Practices

Putting cryptographic primitives together is a lot like putting a jigsaw puzzle together, where all the pieces are cut exactly the same way, but there is only one correct solution. Thankfully, there are some projects out there that are working hard to make sure developers are getting it right.

The following advice comes from years of research from leading security researchers, developers, and cryptographers. This Gist was [forked from Thomas Ptacek's Gist][1] to be more readable. Additions have been added from

Why F#?

I got inspired to answer the questions posed to F# experts on "Why F#?". I have no claims to be an F# expert but I thought the questions were interesting.

How and when did you get started programming in F#?

I believe I started to look at F# around 2008. I am a language-curious person and was at the time working as a .NET developer so I naturally was excited when discovering F#.

How long did it take before you could code real world apps as much or more productively as in C#?
