Deja au intenția să elimine scutirea de impozit la cei ce întrețin software. Numai cei ce produc software sa fie scutiți de impozit.

Cand vine vorba de validare de email e mai complex. Ai aici explicatii + o expresie regulara la final. Daca sapi mai bine, este un site unde se compara diferite expresii regulare pentru email-uri. http://stackoverflow.com/a/201378/1886542

Merita. Daca lucrezi cu multe librarii care isi schimba API-ul sau raspunsul, e mult mai ok sa testezi cu o singura comanda toata aplicatia(mai ales daca e complexa) decat sa pargurgi aceeasi pasi la fiecare schimbare.

Iti recomand sa te bazezi pe programare dinamica, siruri de caractere(tot felul de algoritmi cum ar fi KMP) si grafuri. Deasemenea algoritmul lui Lee sau Fill sunt importanti la OJI pentru clasa a 10-a Ai aici cam ce ar fi necesar: Training path (pana la Grafuri - dar nu strica sa le stii si pe alea).

De curios, cum crezi ca poti pune Android pe Lumia 520? Ai gasit ceva concret? Nu cred ca poti pune Android pe Lumia 520 din varii motive(platforma, API, etc).

Mersi pentru recomandari. Am reusit cu chntpw din pack-ul care l-am precizat in primul post dupa mai multe incercari(nu mi-am dat seama ca, contul e blocat). Ophcrack era prea mare, desi l-am luat in calcul de prima data.

Daca aveam cum sa descarc imaginea, descarcam ophrack, sau altceva similar si nu ma oboseam sa mai caut. LE: O sa vad ce distributie o pot face sa porneasca si sa instalez chntpw @seboo00111 o sa reincerc.

Am nevoie de o distributie de linux cat de mica care stie sa reseteze parola la utilizatorii din Windows 7. S-a uitat parola la un pc si cred ca e inutil o reinstalare, iar o distributie ca si SystemRescue e prea mare pentru a fi downloadata(pentru ca am internet pe modem, contorizat). Am incercat acesta dar nu am reusit sa o schimb, desi scrie Password Changed. Mersi.

Stiu eu. Vezi ca ai un buton colorat, in partea stanga a spatelui monitorului, si care are o forma de paralelipiped bidimensional colorat in rosu si pe care scrie X. Da clic si asteapta ip-urile cu useri si parole.

@bcman - pentru datele puse de tine, trebuie programare dinamica, sau backtracking in cel mai rau caz. O sa retrimit solutia cand o sa am timp.

Mersi de challenge!

Cu functia exec() Ai aici mai multe(nu am experimentat niciodata pe Windows): http://www.php.net/manual/en/function.exec.php#43917

Nu stiu ce sa cred, avand in vedere ca e scris pe *protv.ro. Dar totusi, din cate vad, "se mareste gogoasa" si la un moment dat va exploda. Deci tind sa cred ca trebuie sa purced cat mai repede in a cripta hdd-ul, cumpara un VPS si facut VPN, utilizare de email-uri criptate, IM criptat, SSL pe RSA, samd.

Oare n-ar fi mai ok sa se implementeze un plugin/modul(nu stiu cum e treaba la vBulletin) care nu afiseaza categoria X sau Y daca nu ai Z posturi? Sau R reputatie? Sau V vechime?

Malware that takes computers hostage until users pay a ransom is getting meaner, and thanks to the growing prevalence of Bitcoin and other digital payment systems, it's easier than ever for online crooks to capitalize on these "ransomware" schemes. If this wasn't already abundantly clear, consider the experience of Nic, an Ars reader who fixes PCs for a living and recently helped a client repair the damage inflicted by a particularly nasty title known as CryptoLocker. It started when an end user in the client's accounting department received an e-mail purporting to come from Intuit. Yes, the attached archived zip file with an executable inside should have been a dead giveaway that this message was malicious and was in no way affiliated with Intuit. But accounting employees are used to receiving e-mails from financial companies. When the receiver clicked on it, he saw a white box flash briefly on his screen but didn't notice anything else out of the ordinary. He then locked his computer and attended several meetings. Within a few hours, the company's IT department received word of a corrupt file stored on a network drive that was available to multiple employees, including the one who received the malicious e-mail. A quick investigation soon uncovered other corrupted files, most or all of which had been accessed by the accounting employee. By the time CryptoLocker had run its course, hundreds of gigabytes worth of company data was no longer available. "After reading about the ransomware on reddit earlier this week, we guessed [that it was] what we were dealing with, as all the symptoms seemed to be popping up," Nic, who asked that his last name not be published, wrote in an e-mail to Ars. "We went ahead and killed the local network connection on the machine in question and we were immediately presented with a screenshot letting us know exactly what we were dealing with." According to multiple participants in the month-long discussion, CryptoLocker is true to its name. It uses strong cryptography to lock all files that a user has permission to modify, including those on secondary hard drives and network storage systems. Until recently, few antivirus products detected the ransomware until it was too late. By then, victims were presented with a screen like the one displayed on the computer of the accounting employee, which is pictured above. It warns that the files are locked using a 2048-bit version of the RSA cryptographic algorithm and that the data will be forever lost unless the private key is obtained from the malware operators within three days of the infection. “Nobody and never will be able to restore files” "The server will destroy the key after a time specified in this window," the screen warns, displaying a clock that starts with 72:00:00 and counts down with each passing second. "After that, nobody and never will be able to restore files. To obtain the private key for this computer, which will automatically decrypt files, you need to pay 300 USD / 300 EUR / similar amount in another currency." None of the reddit posters reported any success in breaking the encryption. Several also said they had paid the ransom and received a key that worked as promised. Full backup files belonging to Nic's clients were about a week old at the time that CryptoLocker first took hold of the network. Nic advised them to comply with the demand. The ransomware operators delivered a key, and about 24 hours later, some 400 gigabytes of data was restored. CryptoLocker accepts payment in Bitcoins or through the MoneyPak payment cards, as the following two screenshots illustrate. The outcome hasn't been as happy for other CryptoLocker victims. Whitehats who tracked the ransomware eventually took down some of the command and control servers that the operators relied on. As a result, people on reddit reported, some victims who paid the ransom were unable to receive the unique key needed to unlock files on their computer. The inability to undo the damage hit some victims particularly hard. Because CryptoLocker encrypted all files that an infected computer had access to, the ransomware in many cases locked the contents of backup disks that were expected to be relied upon in the event that the main disks failed. (The threat is a graphic example of the importance of "cold," or offline backup, a backup arrangement that prevents data from being inadvertently overwritten.) Several people have reported that the 72-hour deadline is real and that the only way it can be extended is by setting a computer's BIOS clock back in time. Once the clock runs out, the malware uninstalls itself. Reinfecting a machine does nothing to bring back the timer or restore the old encrypted session. Earlier this year, researchers from Symantec who infiltrated the servers of one ransomware syndicate conservatively estimated that its operators were easily able to clear $5 million per year. No wonder CryptoLocker has had such a long run. As of last week, more than three weeks after it was first published, the reddit thread was still generating five to 10 new posts per day. Also a testament to the prevalence and staying power of CryptoLocker, researchers from security firms TrendMicro and Emsisoft provided technical analyses here and here. "This bug is super scary and could really wipe the floor with lots of small businesses that don't have the best backup practices," Nic observed. "Given the easy money available to scam operators, it's not hard to see why."

What do you think?

Are un prieten, dar nu stiu exact modelul. Te anunt maine(1 oct) prin PM, daca mai esti interesat si daca mai e disponibil spre vanzare. EDIT @dukusss: nici nu ma uitasem in calendar.. Sorry.
