|Searching google and exponential growth
searching for the word "google" in google search engine yields:
"Results 1 - 10 of about 893,000,000"
Due to their exponential growth, wait and see when it will reach 1,000,000,000 ...

|PageRank - can you find 10/10 ?
I didn't blog for quite a time, so...
I had started noticing the PageRank of google Toolbar;
I had tried to look for pages whose PageRank is higher than 8, but
could not find any. (except , of course, www.google.com - how humble ;
even gmail.com was only 8/10).
Even popular sites (just for example: http://www.nytimes.com/
and www.lwn.net) had a PageRank of 8/10.
Can you find one more 10/10 PageRanked page ?

|KVM and Windows under Linux
Haven't blogged for quite a time.
I finally had some time to try and install KVM (Kernel-based Virtual Machine), and
Windows under KVM on a Linux machine.
And it is SO good to see Windows under Linux. The
expression itself, "Windows under Linux", is also good to hear...
Works like a charm!
If you have one of the new processors with virtualization extension - try it!
Avi Kivity, who wrote KVM, tought the Xen team and the linux world a lesson;
while fruitless trials from the Xen team were made for quite a period to integrate
their project into the linux kernel, the KVM was integrated into the
Linux kernel quite nearly after the first KVM patches were sent to the
linux kernel mailing list. (LKML).
Avi Kivity is a very talented programmer who was the system architect
in an Israeli Start Up where I once worked. We all admired him;
first time we saw the code he developed we just couldn't believe - it was so
complex (including high level of nesting of templates). We all wish KVM and him

|Grub Tip (linux versus solaris)
A Grub Tip:
I had some feeling that there is some differnce between
the linux grub and the solaris grub.
The linux grub does not supports ufs; in fact, the solaris
x86 grub is a patch for linux grub. It was not sent yet upstream.
So I looked a bit at it.
When you inside a "grub" program (not
from a dedicated connected terminal,for example from ssh) and want
a quick way to know if it is the "grub" of solaris or "grub" of linux
(it happens sometimes, believe it or not,
especially when you mess with grubs all day)
You can run "TAB".
The TAB lists possible command completions.
In linux there 52 commands, in solaris there are 53 commands !
They are the same except the last one.
So Look at the last command:
in Solaris (x86) there is a command "verbose" at the end of
In linux (at least, FC5) the "verbose" command does not appear.

|Fedora Core 6 and virtulaization
1) I had installed Fedora Core 6 which was released 2 days ago (24.10.06).
Fedora Core 6 came bundled with xen virtulaization:
uname -r : gives
Also there are 2 virtualzation rpms bundled within Fedora Core 6 : gnome-applet-vm-0.1.0-1 and virt-manager (written in pyhton) inside.
2) There is a short article in lwn.net today (I'm subscribed on lwn.net , and it's certainly recommended for kernel hackers!)
about Avi Kivity virtualization patch:

|Fedora Core 6
Fedora 6 release was postponed to next week, 17 october ; There are some issues
regarding ext3, iscsi , SElinux, and more.
I hope that they will fix the annoying FC5 installation bug:
when you use the cd installer on a x86_64 machine with a SATA disk (maybe also
x86 ? I did not try) , in you press "Enter" to start the installation immediately
at the beginning, there is a kernel panic ! this does not occur in non sata
disks. It took me some scratching of head and googling to reveal what should be done:
simply enter gibrish instead "enter", it will give you an error message , and then
press "enter" ! clever and sophisticated . It was in linux-il mailing list
where I found this.
I am igor to see whether this bug is fixed in FC6.
