This post is dedicated to people who like me have OS X 10.6 (Snow Leopard) disk image and have no DVD disk or 6Gb flash drive and want to upgrade from OS X 10.5

I’m a total OS X newbie, but this way works for me and probably will help to someone. If you decided to try the way described below, you are doing this on your own risk!

Recently I needed to install Windows XP under VirtualBox on my Fedora Core 9 mashine.

After a successfull VirtualBox installation, I got an error when trying to install Windows from .iso image:

VirtualBox can’t operate in VMX root mode. Please disable the KVM kernel extension, recompile your kernel and reboot (VERR_VMX_IN_VMX_ROOT_MODE).

The error message means your kernel has loaded kvm module which conflicts with VirtualBox.

How to fix the problem?

Do you know IE has a limit of 32 external CSS files? Do you know each file should be up to 288Kb to get parsed?

I didn’t know and found this just a little bit of time ago. As Google says IE has a bug (well, someone names this a limitation which makes sense): number of external CSS files you can import is 32, everything beyond the 32th file will be ignored. In addition to this - CSS file size cannot exceed 288Kb, otherwise it will be ignored as well. This limit is present in Internet Explorer 6/7 and 8.

Seems IE is the only browser with such a limit, other browsers worked well for me with 33 external style sheets (Firefox, Opera, Safari, Google Chrome, Konqueror).

Solution: aggregate multiple CSS files in bigger ones. As my experience shows - most files are 5-20Kb in size, and one 40Kb file is faster than 8×5Kb.

I have problems with my video card detection/drivers from time to time due to automatic updates of my Fedora Core 9 system. The old driver I used to fix the problem doesn’t work anymore, thus I run this to get things working:

#nvidia-installer -f

This command will cause connect to the NVIDIA FTP server ‘ ftp://download.nvidia.com ‘ and determine the latest available driver version. If there is a more recent driver available, automatically download and install it.

Why don’t I just run

#nvidia-installer --update

?

Because if you have to do this from time to time, there may be no newer driver available, thus the system may believe the latest driver is already installed and will do nothing.
With the ” -f ” flag nvidia-installer performs “forced update” - the driver will be downloaded and installed forcedly.

Now, just reboot your mashine.

Sometimes I play Internet Backgammon when I’m on Windows box (can be found under Start->Programs->Games in a standard Windows installation). I haven’t ever played the game in offline nor even knew its rules, but after a few tries found the game is interesting - mostly due to the fact you play over internet with live people, not with the computer - thus it could be quite hard to prognose turns of opponent.

I cannot say I’m very successful player, but sometimes I have a luck to win

After some time I was playing Internet Backgammon I figured there is a special category of players - Read the rest of this entry »
