Google: is it the new microsoft??

I have read today that google is building a new OS called chrome OS. This new OS is based on linux and will be installed essentially on netbooks. With this OS, google aims to produce a secure, fast and reliable OS. But the main goal of google is to make the access easier to the web and its services

The big question is: is google following the same way as Microsoft did 20 years ago ??

I hope that google will not do the same mistake and to keep the Internet open to every one.

how do we have to expect from Fedora 11

I like fedora very much. I always install the last version as soon as it becomes available. However, I am still disappointed with the fact that Fedora (and more generally linux) does not still support many hardware. I think that at this step, linux commuties have to make a very hard work on this field.

In this period, I am finding great problems to install easycap video adapter on linux.

I hope that things will be easier soon.

reinstall grub

Often, when you use windows you will have to format you system because of virus and spyware.

If you are using linux in dual boot with windows, then, grub will be erased and you will not be able to boot to linux.

Fortunately, it is easy to reinstall grub if such situation happens. Just follow these steps:

1. Boot with the installation media (CD/DVD)
2. Choose rescue existing system
3. The system existing will be mounted on /mnt/sysimage
then, execute the following commands

chroot /mnt/sysimage

and then

grub-install /dev/sda

assuming the your fedora system is installed on /dev/sda. You can check this with fdisk -l.

good luck

Using the webcam with kernel 2.6.27

After updating you kernel to version 2.6.27, some applications like skype and cheese may crash or not be able to play webcam videos. This is due to the incompatibility between V4L1 and V4L2.

Note that drivers gspca has been integrated in the kernel starting from 2.6.27 and use V4L2 instead of V4L1.

The solution for this problem consists on downloading the compatibily labraries and then to load them before starting the application.

On Fedora, this can be done with the following commands (as root):

For i386

wget \

rpm -ivh libv4l-0.5.4-1.fc9.i386.rpm

LD_PRELOAD=/usr/lib/libv4l/ cheese

For x86_64

wget \

rpm -ivh libv4l-0.5.4-1.fc9.x86_64.rpm

LD_PRELOAD=/usr/lib64/libv4l/ cheese

How to change the mac adress in Fedora

Some people may need to change the mac address of their ethernet network cards. This can be easily done with fedora with command line. Just follow the steps below:
1. Log as root on a textual console (ctrl+F2) or through "su -" command in your console
2. Print your network configuration with ifconfig

[root@localhost ~]# ifconfig
eth0 Link encap:Ethernet HWaddr 00:23:8B:6A:7E:9E
inet addr: Bcast: Mask:
inet6 addr: fe80::218:8bff:fedb:7e9e/64 Scope:Link
RX packets:79086 errors:0 dropped:0 overruns:0 frame:0
TX packets:40319 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:72461556 (69.1 MiB) TX bytes:5245562 (5.0 MiB)

Here, eth0 is the ethernet interface of your system. The mac address is put in red.

3. Change your mac address using the following syntax

ifconfig eth0 hw ether 00:18:8B:CA:7E:90

The new value (in green) must be hexadecimal

4. if you have a dhcp server that distributes the adresses automatically, then request a new adress for your eth0 interface

[root@localhost ~]# dhclient eth0

5. Now, your interface is up and have a new mac and IP addresses. This feature may be useful if the network administrator ban you according to the mac adress, for example .........
