CS50 (computer science 50 harvard-course)

[Usr6]

Introduction to Computer Science I is a first course in computer science at Harvard College for concentrators and non-concentrators alike. More than just teach you how to program, this course teaches you how to think more methodically and how to solve problems more effectively. As such, its lessons are applicable well beyond the boundaries of computer science itself. That the course does teach you how to program, though, is perhaps its most empowering return. With this skill comes the ability to solve real-world problems in ways and at speeds beyond the abilities of most humans.

Wow, imi place vocea lui chiar ma ajuta sa ma concentrez, dar exista vreo versiune downloadabila a cursurilor? chiar mi-ar placea asa ceva

[adonisslanic]

Hmm uite, mai simplu ia linkul asta Introduction to Computer Science I / OpenCourseWare are si alte cursuri decat cs50. Eu o sa fac ca la scoala o ora pe zi un clip si invat, fac temele de acolo etc. E chiar super ca ne lasa sa vedem aceste cursuri

Edit: Mai tare chiar, uite cursurile curente, daca reusiti sa ajungeti la zi, puteti lucra odata cu studentii "realtime" http://cs50.tv/2010/fall/

super tare m-am uitat la ala cu "Introduction to Programming and Scratch" si e super tare

LE: Foloseste mult acest program Scratch la cursuri...

dar exista vreo versiune downloadabila a cursurilor?

support , me wants too.

[adonisslanic]

Matzo, uite aci This is CS50 / Lectures e siteul lor pentru elevi, sunt uploadate cursurile in aceeasi zi in care sunt facute, au si download, au si notite, si exemple de cod

[black_death_c4t]

thnx pisi .

[Usr6]

pt practica ei au servere linux dedicate;)

am gasit un shell free pe care se pot pune in practica exercitiile respective (nano,gcc, php,mysql, etc)

Creare cont nou:

Host shellmix.com port 30

Login : newuser

Password : newuser

conectarea se face pe portul 22 cu datele personale

shellmix

*poate foloseste cuiva:)

Daca fiecare profesor ar fi explicat cu o asemenea pasiune si nu numai, ce bine ar fi fost, chiar m-as fi dus la scoala de placere.

Multumesc pentru link-uri si info, nu stiam de ele, sunt super.
