S-a inchis proiectul. S-au strans foarte putine articole. Poate se va redeschide ideea dupa ce termin cu sesiunea, cand voi termina un articol deja inceput si poate voi mai scrie unul.

Inca o "chestie" aniversara. Multumim pentru activitate, sper ca veti fi activi si pe viitor, dar sper sa va mai si maturizati si sa va ganditi si la lucruri mai serioase cum ar fi temele acestui forum. PS: Daca vreti un viitor in domeniul informaticii, ar trebui sa va ganditi mai profund la ce am spus mai sus, aici va puteti forma o baza solida, dar totul depinde de voi. La cat mai multe posturi (de o calitate mai ridicata)!

Cred ca Viz0n. La profil scrie ca e o fata de 15 ani dar nu prea cred. Oricum, nu asta conteaza, conteaza ca se ocupa de problemele site-ului. Au fost niste probleme cu inregistrarile, cu DNS-ul pentru IRC si altele si au fost remediate foarte repede. Se ocupa de site.

Tampenie veche si inutile. Topic inchis.

E un forum mai serios, cateva persoane care posteaza, le pasa de forum si de informatiile care se posteaza, nu prea am vazut aberatii sau intrebari stupide. Imi place, cel putin momentan. Stiu ca probabil ati auzit de el. http://r00tsecurity.org/forums/

Si pe ce criterii se vor alege utilizatorii? Zicem ca imi fac contul "x". Cont care nu il am si pe alte site-uri, deci nu vei putea stii cine sunt. Cine va fi ales, si cine nu? Se pot face neaprobari pentru useri ca "HackerCracker1337", dar cred ca numele de utilizator nu este de ajuns.

"Security Stuff" este o arie vasta. Pe langa un numar limitat de utilizatori care vor fi alesi de tine si de membrii alesi de tine, care ar fi noutatile? Va fi strict tehnic si nu se vor permite aberatiile?

Anti-Trojan Elite 5.3.2 + Patch Anti-Trojan Elite™ (ATE) is a malware remover, it can detect and clean malware in disk or memory. Malware is software designed specifically to damage or disrupt a system, such as a trojan horse, a spyware or a keylogger. ATE contains a Real-Time File Firewall, it monitor system and clean malwares immediately. It is also a system security tools, you can view and control processes and TCP/IP network connections. Anti Trojan Elite provide a real-time malware firewall for user, once a trojan or keylogger would been loaded, the ATE can detect, block and then clean it in time. The ATE can detect more than 35000 trojans, worms and keyloggers currently, and the number of malware ATE could clean is growing up very quickly, we collect world-wide malwares, user can using our auto live update feature to get the power to clean these new malwares in time. Anti Trojan Elite has some useful utilities especially.

Yersinia: Network Exploition Tool Screenshot: http://www.yersinia.net/img/gui.png Yersinia is a network tool designed to take advantage of some weakness in different network protocols. It pretends to be a solid framework for analyzing and testing the deployed networks and systems. This is not any other network scanning and analysis tool like Nmap. This is a real hacking tool already loaded with exploits including the latest VTP(VLAN Trunking Protocol) DoS exploit. Attacks for the following network protocols are implemented: * Spanning Tree Protocol (STP) * Cisco Discovery Protocol (CDP) * Dynamic Trunking Protocol (DTP) * Dynamic Host Configuration Protocol (DHCP) * Hot Standby Router Protocol (HSRP) * IEEE 802.1Q * IEEE 802.1X * Inter-Switch Link Protocol (ISL) * VLAN Trunking Protocol (VTP) Attacks pertaining to specific network protocols: Spanning Tree Protocol 1.

700 Mbps = 700 / 8 MBps = 87.5 MBps. Insa nu cred ca se pot atinge asemenea viteze de pe un calculator simplu. Poate cu cine stie ce procesor, iar datele de se trimit sa nu fie citite de pe hard-disk. In RAM, in C, viteza de scriere (memset) era de de aproximativ 15 MBps, si 50 MPps la citire, desigur, asta tine de procesor. Deci sunt multe limitari, nu numai mediul de transmisie e important. Asta daca nu va referiti strict la transfer, asa da, cred ca se poate fara prea mari probleme, fibra optica rullz. Ca viteza, stiu ca facusera niste teste cu un satelit Alcatel si ajunsesera la 5 GBps, dar nu ai cum sa scrii atatea date intr-o secunda pe un hard-disk de exemplu. Dar da, se pot atinge 2000 GBps daca faceti suma la date trimise de la mai multe calculatoare... Oricum nu mi se pare prea amuzant, din moment ce am vazut sute de cazuri mai "naspa" decat acesta.

LibreOffice, alternativa gratis pentru Microsoft Office Cum s-a format LibreOffice: La data de 28 septembrie 2010, unii membri al proiectului OpenOffice.org au format un nou grup numit The Document Foundation, ?i au pus la dispozi?ie o noua versiune de OpenOffice.org, care s-a bazat pe versiunea OpenOffice.org 3.3 beta. Acest grup s-a format dupa ce compania Oracle a cumparat Sun Microsystems (fostul sponsor si fondator al OpenOffice.org), acestia urmând sa nu mai distribuie in format OpenSource, suita de aplicatii OpenOffice. The Document Foundation le-a propus celor de la Oracle sa doneze proiectul OpenOffice.org. Dupa ce acestia au refuzat sa doneze proiectul, la sfarsitul lui Octombrie 2010, 33 dintre developerii suitei OpenOffice s-au la The Document Foundation, pentru a sprijini LibreOffice. Ce este LibreOffice: LibreOffice este o suita de applicatii office, care este compatibila cu alte suite majore de birou (Microsoft Office), ?i disponibile pe o varietate de platforme. Scopul este de a produce un set de de aplicatii de birou compatibil cu cel distribuit de cei de la Microsoft, cu sprijinul ODF disponibile pentru toata lumea gratis. Ca software liber, utilizatorii sunt liber sa descarce, modifice, utiliza ?i distribui LibreOffice. Bla bla...
