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. .

Nu a fost vorba de slowloris, ci de ceva mult mai naspa. Am pus un link la topicul lu' tromfil, in care intreba despre CloudFlare, dar nu cred ca a citit cineva. Istoria pe scurt, pentru cei care nu au chef sa citeasca in engleza: Site-ul Spamhaus a fost atacat si a fost pus repede jos. Metoda folosita: exploatarea open DNS-urilor, pentru a amplifica puterea botnet-ului propriu. Mai precis, ataci cu o putere mai mare de 1 pana la 100 de ori decat banda maxima pe care o are botnet-ul tau, ducand la cifre impresionante ( 300 Gbps DDoS ) , care se vor mari mereu, pana se ia vreo masura cu open DNS-urile nesecurizate. Cei de la Spamhaus i-au contactat pe cei de la CloudFlare, sa-i ajute in a mitiga atacul. CloudFlare a primit in prima faza un DDoS de 75Gbps, fiind cel mai mare de pana atunci, lucru insa care nu i-a afectat prea tare, reteaua lor fiind tocmai construita pentru astfel de lucruri. Am verificat si eu ... si cei care i-au atacat nu au mai reusit sa puna off-line Spamhaus. Zilele urmatoare, reteaua CloudFlare a fost atacata cu pana la 120 Gbps si iar nu a patit nimic. Atacatorii, vazand ca nu au succes cu ei , au zis sa atace furnizorii de internet ai CloudFlare ... si au facut-o cu un total de pana la 300 Gbps, rezultand o incetinire a internetului la nivel global. Daca doriti, puteti sa cititi in engleza, de pe blog-ul CloudFlare pentru ca acolo lucrurile sunt prezentate intr-o maniera tehnica ... si nu in una cancanisto-alarmistica, asa cum o face mass-media.

Nytro nu fi rau Daca ei o duc bine si se ard repede pe bani grei sa fie in bafta lor. Cine e baiat si stie sa ramana in banca lui, nu il deranjeaza nimeni si are si bani, si BMW-uri si e si interlop....
