Are you already using Windows 7? Well, create a new folder name it “GodMode.{ED7BA470-8E54-465E-825C-99712043E01C}” (without quotes) and hit Enter. Hahaaa Icon changed you see. So open it, to see what’s inside (:

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:

Just loved the HP Compaq LA2405wg 24-inch Widescreen LCD Monitor. Its specs are quite good with 1920×1200 resolution and DVI-D with HDCP support. It also has new DisplayPort interface (just in case I got a Mac notebook). I am looking for a new monitor recently and think this is a good replacement for my current HP 2045w one wich is just 1680×1050 resolution and lacks the HDCP support. With price at 240€ it is a good choice for everyone, I think.

Announced on Dec 3rd, just a week ago, Google Public DNS service is still in testing/beta phase, so no SLA is available, but I’ve decided to give it a try. Google Public DNS uses Anycast to connect you to the closest DNS server, which in my case happens to be at ~42 msec away. Which is better than OpenDNS one at ~55 msec, but worse than Level 3 DNS 4.2.2.2 at ~36 msec. Right now I am using both Google Public DNS servers 8.8.8.8 and 8.8.4.4 as forwarders to see if any change in end-user experience would be noticeble. Will see.

How To Upgrade Windows 7 RC To RTM? Check out the following article after the jump. Tested, and working just fine minutes ago. Just one side note: when prompted to download setup updates, chose not to do that…

Tired from all those commercial SMS games you receive now and then from your mobile operator?! Happily if you are on Mobiltel AD, just send text “stop 500″ to 17867:
Edit: 500 is the name/code of the specific game. To stop others send their name/code.

As I said I shall have any news about ATI Radeon HD 4770, I wouldn’t knew I will have to play with two of those. That’s right, I have setup two 4770 in cross-fire mode, but that’s not all of it - as a bonus a brand new AMD Phenom X2 II 550 BE is under the hood, bringing a huge increase of speed and cache compared to AMD 7750 BE (from 2MB to 6 MB L3 cache).
Check out the screenshot above. You can click on image to expand it. All is done on air-cooling. The CPU is OC from 3100 to 3511 MHz (+13.2%) without raising the voltage! And 4770 OC is quite limited by Catalyst Control Center from 750/800 to 800/850 MHz (+6%) which is nothing at all. The real potential of those cards is like 850/1100 MHz. To be continued…

I just posted a comment in Picasa Web Albums in Bulgarian, and it was automatically translated in English. Good work, Google!

So is CUDA doing anything? You bet. There’s a 35% drop in output time with GPU acceleration enabled, so CUDA is plainly throwing everything it can at the job. But here’s the interesting part: AMD and Nvidia show essentially the same encode time in CPU-only mode, but Stream yields a 108% performance gain, easily trouncing the CUDA result while averaging 40% less CPU utilization than CUDA (read more).

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.
