| 246702 | 2004-06-22 06:03:00 | Again... here's another silly question? What is DEP (Date Execution Protection?) cheers chiefnz |

Yes it doesn't support hardware DEP, you would need an Athlon 64 for that, but it does say Software DEP is enabled, and how do you disable that? The option for disabling is greyed out on mine. Chief, DEP is supposed to stop certain code from executing inside the CPU, like viruses etc which can exploit certain areas of the memory in which only the OS is supposed to reside. I think Software DEP could be eventually expanded to stopping MP3s and all sorts of stuff from running. -> Coming to a windows update near you! |

DEP or "the NX bit" is a feture in new CPUs that meansa program can mark the data/stack part of the RAM or NX or "no-execute". the effect of this is to make buffer overflow exploits much harder to write. NX-bit has nothing to do with MS trying to run the world and is NOT related to software copy protection. to take advantage of the NX feture you need a CPU with NX support and an OS with NX support. linux is getting NX support, windows XP service pack 2 will give NX support. both AMD and Intel support NX-bit on newer CPUs. basicly the NX-bit is a backstop for bad programming :-) |

| 246705 | 2004-06-22 06:18:00 | Im pretty sure the 2.6 kernel series already supports the NX register. IMO its a good and bad thing... Basically lazy programmers now have even less reason to check and double check their code! |

I agree that it is both good and bad, but anything that slows down the hackers must be good. anything that makes life easer for programmers is good. anything that adds to the cruft in the OS/CPU is not so good...... |

| 246708 | 2004-06-22 08:00:00 | A bit more confused with all this technobabble. What is SP2 RC2 ?" Its at the "near" final stages at the moment (RC2), and are for public to download. Try it and see." And it is 230MB+ an all night job to download. And the download stalled halfway through due to some other techno stuff which would send me through the ceiling. When this programme is finally released to the public and for non techno idots like me, can one get it on a CD or do I hire an expert to put it into my machine. I am fast beginning to think that going on the internet is not worth all the trouble and I will reserve my computer for shooting down ME109's as well as doing my books. | heaton (3697) | ||

There are three camps in this Derek, it will be used for more than they're letting on (and to "our" detriment), it could be used for other than what the implementers/adherents intentions state it is for and, there is no way it is anything other than what the implementers/adherents state it is. So we're all allowed to be a little confused or in doubt as to where it is going. Heaton, yes you can download it and yes it's near the end of it's testing cycle (beta program) RC2 is Release Candidate 2 and the hope is there will not get to RC4 because, as above, the malicious amongst us will already be working on breaking its beefed up security and it will be giving them pointers as to how to crack un-patched XP machines which, is most them until the final SP comes out (assuming everyone is good and patches immediately).

I'm betting that within 2 weeks of the final of SP2 being released there will be a "critical" exploit which will require everyone to update their machines again. |
