Sony produces great stuff, but when it comes to the drivers support, they are unbelievably inconsistent and confusing with their driver releases.
I have a Sony Vaio VGN-SZ770N notebook and it was a painful experience to get Windows 7 32bit install with all the proper drivers, and for the 64bit, it was even harder.
Bluetooth was …

For example when you try to move …

Some of you probably use dedicated virtual hosting like Media Temple and are aware that the big hosting providers like to take their time and test all new versions of software prior to deploying it and making it part of their default server images.
Paralels Plesk version 8 for example is somewhat slow and not …

It is very sad to watch people struggle with the previous OS attempt (or should I say failure) of Microsoft called Vista. Especially now, when Windows 7 is out.
I am not a Microsoft hater, nor I am too attached to Linux as a …

I was a huge fan of Netstumbler (the WiFi SSID scan tool with GPS support), however their lack of imagination and willingness to advance together with the existing and future technologies and platforms somewhat rendered them non-attractive to me anymore.
Yes, their tool does not work on Windows 7 and I can state as …

Well, it has been a week since I got this phone.
It looks like the Nokia E73 was another rushed out product, this time unfortunately by Nokia (under pressure from T-Mobile I am sure).
Since I am so called “power user”, I tend to notice many things that can be really annoyed for people who want …

3. Set the php safe-mode …
Since it has been a real adventure to gather all the pieces from this puzzle, I decided to write a guide for folks who are about to do this.
