Graphic card burning by malicious program or hacker: possible.

Since furmark has been limited in drivers I searched for a way to heat up my cards (2x GTX 580 SLI).
I came across MSI Kombustor, but I noticed only one card was used.
Playing with NVIDIA Inspector I created a profile for kombustor 3 and now both cards are used.
Fiddling with the settings I found a way to maximize heat.
For example: with my setting (air cooled, stock fans, custom fan curves and fully overclocked cards) using Valley in Extreme HD mode, my temps are 82 for the primary card and 69 for the secondary (after an hour of looping).
With kombustor3 and the profile I created, the cards heat with a steeper curve up and maximize (99 degrees) in a few minutes, then thing get weird and ugly :D

If you are interested in further testing here is the setup:

1) MSI Afterburner Version 4.1.0.7013
2) MSI Kombustor 3 (launched clicking the K in MSI Afterburner: this will run it in windowed furmark mode)
3) NVIDIA Display Drivers 335.23 (which are the fastest for my cards, the newer drivers are 5 to 10% slower)

Let me know and be careful to temps. If you don't have a good cooling this may harm your cards.

Here is a screenshot of a few seconds of run:

TP-LINK Configuration file encrypt and decrypt.

Here we go! TP-Link is another company that thinks that security by obscurity could ever work. If you "backup" the configuration from most TP-Link routers, you will get a .BIN file which is "encrypted". Use this utility below, to decrypt it (so you can edit it) and encrypt it again. Have fun.

Powerline Ethernet fun and secrets.

Many 200 Mb/s powerline adapters nowadays are based on the INTELLON 6300 chipset. Despite what can be thought looking at them, they are all using the same hardware and firmwares. I heard many people with Netgear XAV101 or Linksys PLK 200 or PLE 200 having problems after firmware updates and many other people with other brands having much more problems because of lack of support or configuration/upgrade utilities. So let me explain a few things I learnt studying them. Many of 200 Mb/s powerline ethernet adapters follow the "HomePlug AV" standard. (85 Mb adapters use HomePlug 1.0 standard which is completely different). This standard uses ethernet broadcast packets using the HomePlug AV protocol. The interesting thing is that their firmware is made of two different parts: a .PIB file (Parameter Information Block) and a .NVM file (the code itself). In the P.I.B. there are many interesting things: The branding (mac address, device name, etc) and the tone map. I test

Your own CORS ANYWHERE proxy on CLOUDFLARE

Hello again! Many of you probably hate as I do CORS because it hinders the very nature of internet, which is SHARING. There are some services to circumvent this commercial  restriction, one of these is the famous "cors anywhere". So yesterday I decided to make my own and allow you to make your own in only 2 minutes. To do so you just need a cloudflare account (can be set up in 1 minute). The you can upload my worker on it and have your personal very fast cors proxy! So, enough talk, just head to:  https://github.com/Zibri/cloudflare-cors-anywhere The is also a demo online at: https://test.cors.workers.dev Enjoy! Zibri
