Since I just received my Yubikey from Yubico I was eager using it, so I decided to start with my WP blog. It turned out to be an easy 2-step process once I’ve installed YubiKey WordPress plug-in:
The latest Yubikeys firmware supports 2 configurations – one is preloaded from Yubico. Both can be re-programmed to have two independent and separate configurations, including any two of the three alternatives:
The result: From now on, I will need to provide my username/password and Yubikey OTP in order to login to my blog. Yubiiiiiiii!…

Okay, so what /is/ 1337 in the first place? 1337 means Elite. The point of 1337 is to replace all the letters with symbols, and is quite fun to play with. 1337 was first created by some people would wanted to talk in a forum without any outsiders barging in. Some outsiders may have figured out the language and started using it as well. Eventually, 1337 became famous all over the internet. The original use of 1337 is hardly practiced any more, but it survives because many of peope use it for fun.
It takes a long time to translate between regular English and 1337 even if you know all 26 1337 secrets, unless you’re very skilled at it.

Hi there! Again, Overclocking day post. Its has been a while since my last OC day, but I have great news for you:
First, ASUS had released new BIOS versions (for various boards) with improved OC features which refine AMD Core unlocking! Yes, indeed, my AMD Phenom X2 550 processor was recognized as X4 with 4 cores working and unlocked. Pity, Windows always stopped with BSOD no matter what I did. But ASUS did their job well, and in BIOS settings under Unleashed more, you can specify which cores to be unlocked. In my case the faulty core was #3 (starting from zero). So, I was able to boot and load in Windows successfully with 3 working cores: #0, #1 and #2.
Second, I needed a better OC tool to stress the 3 cores. It happened that Orthos is running on 2 cores only, and Prime95 I don’t like since it downloads some data chunks to process, then uploads results. So, a new OC tool was born, and it’s named FFT-z! You can see it in action on the screenshots bellow, next to CPU-z, HWMonitor, FurMark, K10stat and TaskManager applications. FFT-z is not released yet officially, but you can grab a public preview release from here. Expect some new cool features added to it In the next releases.

Imagine your company has hundreds if not thousands of computers. Imagine they are running for at least of a year. How many applications, updates, SP-s were installed meanwhile? How many unused files are left after that? How many temporary files were placed anywhere on those computers? Are your users complaining their computers are getting slow, or that their system drive is full? You want to cleanup! But how?
First of all you download Cleanup Temporary Files (shortly “Cle”) tool. The you setup Logon script for your Active Directory’s users (or OU-s, if you prefer) as this:
REM -- Startup script "user.bat"
REM -- Cleanups the PC temporary and unused files from
REM -- various (hidden) places.
\\SRV-DFS\Files\Audit\cleanup\Cle.exe /custom 32839 /p
then on each user Logon this will happen in the top left corner of the Desktop:

Of course all this could be managed from Cle Configuration application, which brings lots of settings and allows you to cleanup custom specified folders. You can tune up the GUI as well, even you can disable the visuals at all, so Cle would work quietly in the background. Corporate admins could deploy a company-wide Cleanup Policy easily using command-line switches as shows above, and force it to computers using “/s” option.
Noted the magic number parameter after the “/custom”? Well it could be easily obtained from Windows Registry (using regedit.exe) once you have run Cle Configuration. It should be specified as a decimal and not hexadecimal number. Here is its location in the Registry:
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\5GROUP\Cle]
"Selection"=dword:00008047 (32839)
and here is a screenshot of Cle’s Configuration dialog:

I woke up, feeling like some Overclocking should be done today, so I fired my rig’s Power button and started few tools to help me out. The result is my AMD cpu OC from 2700 to 3200 MHz (+18.5%), and my ATI 3870 video card OC from 775/1125 to 837/1215 MHz (+8%). The latest could seems to be not a big deal, but it really helps gaming, I am sure.
Check out the screenshot above. You can click on image to expand it. Now, the Crysis64.exe is calling me…
Edit: Note that CPU OC is using stock voltage of 1.25V. By increasing it to 1.45V you can easily reach 3400 MHz. Quite impressive on air cooling. As for ATI 3870 OC, expect some interesting news next week when I will do ATI 4770 Crossfire testing, so until then.

I came across a very nice tool which could be quite handy when you upgrade your PC. Check it out:
Double Driver is a very simple and useful tool which not only allows you to view all the drivers installed on your system but also allows you to backup, restore, save and print all chosen drivers simply and reliably.

Hi there! I just completed my Intel rig and loaded it with Mac OS 10.5.5 without any issues. Now, that is a GUI (Graphical User Interface) and that’s how it should be done. Also I can tell you it starts in 10 seconds, and shuts-down in 5! Compare that with Windows Vista and you’ll definitely see the difference! I love BSD, so I’m going back to Mac OS exploration…
