Avand in vedere lipsa de activitate la aceasta sectiune, am decis sa deschid acest thread, care probabil va fi urmat de altele daca este primit cu bine Scopul este sa invatati ceva din discutiile ce vor urma si din writeup-urile postate, nu sa concurati intre voi.

Day 01: Detours
Santa receives an email with links to three pictures, but every picture is the same. He talks with some of his elves and one says, that there is some weird stuff happening when loading these pictures. Can you identify it?

Day 03: Manufactory
Today's gift is ready to be manufactured, but Santa's afraid that his factory won't manage to do a production run before christmas. But perhaps you can create it yourself?

Day 04: Language Of Us
You all should know this language, but this one is not that consequent as it should be.

Day 05: Boolean Fun
Santa found a paper with some strange logical stuff on it. On the back of it there is the hint: "use 32 bit".
He has no clue what this means - can you show him, what "???" should be?

Day 07: TrivialKRYPTO 1.42
Today's present is encrypted. Luckily Santa did not use Kryptochef's KRYPTO 2.0 so there might be a slight chance of recovering it?

Day 08: Lost In Encoding
Santa and his elves do not know good encryption, all they have heard about are some basic encodings. Unfortunately they all are bungling and forgotten the recipe.
It's now on you, who has to get it up.
