  1. Solid State Drives are based on flash technology and thus are limited to how many times you can write to them. I would like to increase the life of mine by limiting the amount of writes to it. Ideally you would want to store the Operating System on it and any other applications that benefit significantly from quicker reading speeds that don't require a lot of disk writing. I was thinking that I should create some mount points of directories that are frequently written to so they point to my HDD instead. I am thinking about setting up mounts for C:\Users and C:\Windows\Temp. What would be some other good directories to move off my SDD? Also, I read about disabling certain services like Disk Defrag, Indexing, Super-fetch, and pre-fetch--which some software like SSDFresh does exactly this and more--I am going to check some of those out. What are some other good ideas for increasing the life? Thanks, ansichart
  2. I got my video card working now! There are two power cables, an 8-pin and a 6-pin connector, the 8-pin was not in all the way... I had to really force it in there. Using NovaBench3 I ran all the benchmarks and these are the results And in Windows 7 Experience Index (performance rating on a scale of 1.0 to 7.9):
  3. I got my parts and put everything together. Everything works great.... except for my video card, which is not being detected ): I see that the fan spins on it, so it is getting power. But Windows just fails to detect it. It is using Intel's integrated video card instead. I have tried installing the drivers but it does not recognize my card. I tried disabling the integrated card and installing the drivers and I get the same issue. I made sure that my video card is in the right PCI slot. I think the Video card is a defect/damaged. I'll probably have to send it in for a replacement.
  4. [EDIT]Changed the power-supply to the modular version for less clutter thus easier management and better air-flow. Also removed Windows 7 64-bit Professional on the list since I already have that. New total: $1743.50[/EDIT] Over the last few days I have been picking out parts for my new gaming PC. I have been going back and forth making changes and I think this is my final list for what I am getting: http://pcpartpicker.com/p/42HB After much contemplation I decided to go with Intel's i5 2500k processor as opposed to the i7 2600k. This surprised some people but check out this benchmark on anandtech: http://www.anandtech.com/bench/Product/288?vs=287 As you see the difference in performance is actually really close, especially when just looking at the gaming benchmarks, it is quite negligible; the price difference, circa $100, however is not. Since I plan on overclocking the CPU, I went with a higher quality CPU Cooler, the Thermaltake Frio. The cool (no pun intended) thing about this device is that it uses heatpipes, which takes advantage of the phase transitioning principle. It's a simple idea really; Inside It has a liquid under a low pressure that gets heated by the CPU turning it into a gas which takes energy with it, which then later condenses back into a liquid to repeat the cycle. Regarding the video card, I am going with the HIS Radeon HD 6970 2GB Video Card. Here is a benchmark test chart comparing it to others in the same league: http://www.videocardbenchmark.net/gpu.php?gpu=Radeon+HD+6970 It was difficult to decide weather to go with GeForce (NVIDA) or Radeon (AMD). They both have their pros and cons; My understanding is that the Radeon is better for really high resolution, since it packs in more memory, and it also focuses on the philosophy of giving you "more bang for your buck." On the other hand NVIDIA is higher performance but the price is not as reasonable. I feel like less money in my wallet would be more noticeable than the performance of a slightly better video card. For my purposes the Radeon will be sufficient. And later if I need a performance boost, I can always get another Radeon to crossfire it with. Also, I like to support AMD... but apparently not enough to go with their CPU, sorry AMD but as far as gaming is concerned, Intel is the best way to go. This system will have two hard drives. The OS and Games will go on a 120 GB Solid State Drive. I found that the Kingston HyperX is one of the best performing ones out there. It also is a fair price in my opinion. A lot of the other ones were cheaper but could not sustain a good throughput like this one. The other drive will be just a regular 2 TB SATA which I will be for my Music, Movies, Pictures, Ebooks, etc. I am going to order these parts later tonight unless someone here convinces me to change something up for a better item or deal. Let me know what you guys think, I am looking forward to your comments. (:

  6. If it can't find the function prototype in the configuration file, it will display 5 parameters. I'm not sure if those parameters were grabbed from the stack, or if they were in the registers. Since this is on x86-64 architecture, the function parameter are actually passed via registers.
  7. *SOLVED* Jester01 on ##asm@freenode figured out why. srand is missing from /etc/ltrace.conf Thus, adding "void srand(uint);" to it fixes the problem.
  8. OS: Ubuntu 10.04 LTS Kernel: 2.6.32-25-generic Architecture: x86-64 Compiler: GCC version 4.4.3
  9. Here's my C code #include <stdio.h> #include <stdlib.h> #include <time.h> int main(int argc, char **argv){ int i; srand( time(NULL) ); for (i = 0; i < 15; i++) printf("%d ",(rand() % 100)); printf("\n"); return 0; } Here is me executing ltrace on the compiled program For some reason, ltrace is showing that there are 5 parameters being passed to srand... I was expecting one. What's going on here?
  10. Thanks for the info army_of_one. I was intrigued by this and did some google searching. I found this article which has some good info regarding layer2 encryption (including MACsec): http://www.technewsworld.com/rsstory/57910.html?wlc=1286821396
  11. Just sharing a thought. When I first posted it, I thought it was brilliant. Then I thought about it some more, and I realized how impractical it would be.
  12. If someone is listening, they could grab the two keys out of the air and put them together. The two directional antennas are spaced apart, so the signal would intersect at 1 point, where the client is. * * \ / \ / \ / /\ / \ / \ If there was two computers with wifi NICs along the two paths were they don't intersect, they could put the two key halves together and get the key. I realize this isn't that great, but it's still an interesting concept. It would be better if both the client and the WAP generated a private/public key-pair and then using their private keys to encrypt a pseudo-random-generated chunk of data (of some prespecified size), and then digitally sign it. Then the WAP and Client would XOR together the two chunks of data to produce a key that will be used to encrypt/decrypt (symmetric key encryption) all further communication throughout the duration of their session. I know this procedure (or something close to it) is done in several different protocols, since symmetric key is faster. It uses the best of asymmetric encryption and symmetric encryption... virtually no down side to it as far as I am concerned.
  13. I thought of this neat idea, I don't know how practical it really is.. but an interesting concept none the less. Imagine a Wireless AP that has two directional antennas spaced a significant distance apart (each having a small motor so the antennas can pivot, and point in different directions), and 1 omni-directional antennas. The two directional antennas used to triangulate the client NIC. When a client NIC wants to associate to the WAP, a pseudo-random key is generated by the WAP. Half of the key is sent using 1 directional antenna to the client NIC, and the other half is sent using the other directional antenna. That way, only the client NIC will receive the full key. Then the rest of the communication can be carried out using the omni-directional antenna, encrypted with that key. That way, other clients on the wireless network cannot decrypt other peoples data, because everyone is using different keys that only the WAP knows, and the individual clients know. You could further expand on this, by having a GPS implemented on the WAP and the client's NIC. The GPS coordinates can be used as extra security parameters. Anyway, what are your thoughts about this?
  14. I am looking for a Linux program that creates a virtual interface device that transmits all data through a SOCKS proxy. That way certain applications that don't have proxy support built in can use this virtual device that does all the SOCKS proxy work behind the scenes. I am certain that programs like these exist, however, I am not sure what this would be called.
  15. If you have not had any real programming experience, getting a book is a good idea. I would check your local library first, before you go out and buy a book. Also, you might want to check out the PHP manual page. Even after you know the language, it is virtually impossible to remember all the functions, and it's a great reference page. Also, a good IDE might also be worth checking out, with nice features such as syntax hilighting, code folding, project management, code navigation, etc. Wiki has a nice comparison list of IDEs that is worth checking out.
