  1. Well guys i need the help of a genius!! I have a question that i have to answer now i'm not looking necessarily for the answer but help, iv looked for weeks for the answer but i am just STUCK so here it is: The semSignal() and semWait() operations, provided as primitives by an OS kernel, are defined to be atomic. Explain how this atomicity can be provided in the following cases: a) hardware which provides test and set lock or other composite instruction b) a uniprocessor when no composite instruction is available c) a multiprocessor when no composite instruction is available thanx for any replies i appreciate it
  2. fair enough, but the wiki from Azureus is outdated as talktalk now traffic shape and they do limit downloads on certain times of day.
  3. nope tried those methods and still the same except for excrypted, im not sure how to do that? It works out they allow normal bandwidth for http but torrent activity they give no bandwidth to so could they not just say and if anything encrypted dont allow bandwidth to that too. Just a though but if you can get back to me with the encryption that would be great and ill give it a try. thanks
  4. hey guys just wanted to post this just to make everyone aware of staying away from talktalk. I should be on an 8Mb line and all was fine with download speeds of 800kb/s but now they have fallen to around 30-80kb/s and torrents have been totally blocked. If anyone has any other info or news about this topic i would be grateful to hear from you.
  5. anyone PM me or something if you actively reverse, thanks
  6. nothing much, i do it myself and just wondered where i would get in contact with other reverse engineers.
  7. thanks for that reply, yes this is definitively on lines of what i want. I remember at school we had to program the computer to interface with little lego models i remember mine was a green house and when the temp got to a certain point the vents would open until the temp dropped then they would shut. The other links from your boss would be fantastic, thanks alot.
  8. Hi guys another post lol, just wondering does anyone reverse engineer (before i get slammed for this there are always legal crackme's which i use) so yeh just wanted to get in touch with some people who could help me out or discuss things. thanks :D
  9. Hi guys not sure what to call the topic but im a keen programmer and wondered if there was any kits or just something that will get me on my way to be able to program hardware and some tutorials etc to get me on my way to learning how to. I imagine i would have to brush up on assembly or something. So any suggestions or help would be appreciated thanks :D
