Python 3.0 Introduction

Leave a comment


Python is a freeware open-source cross-platform interpreted scripting language used by NASA ,
Google , Honeywell and many other companies and now days its also being distributed along
with all the major GNU/Linux distros.


Its been one the most favoured scripting languages due to its short and easy syntax which can
perform complex tasks and is easily extended with new functions and data types implemented in C
or C++ (or other languages callable from C). Python is also suitable as an extension language for
customizable applications.


Many people might have tried using python before but on 03 Dec 2008 Python 3.0 was released
which is a major update to python syntax making its interpreter faster and more efficient.

Installing ATI fglrx for compiz Fedora 10

11 Comments

These instructions are for installing fglrx on ATI cards it also removes the flickering that radeon might be giving.
You could also follow the guide at fedora forums but this is more simple.(Using 8.12 Driver)

(if you have followed other methods, please roll-back to previous system state,remove related packages)

1)Get Fedora 9s libdrm

32 Bit

rpm -ivh --nodeps --oldpackage http://mirror.yandex.ru/fedora/linux/releases/9/Everything/i386/os/Packages/libdrm-2.4.0-0.11.fc9.i386.rpm

64 Bit

rpm -ivh --nodeps --oldpackage http://mirror.yandex.ru/fedora/linux/releases/9/Everything/x86_64/os/Packages/libdrm-2.4.0-0.11.fc9.x86_64.rpm

2)Go to AMD official Site Download the driver:

http://ati.amd.com/support/drivers/linux/linux-radeon.html

3)Install driver

./ati-driver-installer-8-12-x86.x86_64.run

4)Create a blank xorg.conf in /etc/X11 (if u have a xorg.conf ,delete and make empty file)

5)

aticonfig --initial -f

6) Edit xorg.conf

Add following to “Device”

   Option      "OpenGLOverlay" "off"
   Option      "VideoOverlay" "on"

7)In the end add

Section "DRI"
Mode 0666
EndSection

Save

8)Backup Old initrd

mv /boot/initrd-`uname -r`.img /boot/initrd-`uname -r`.img.0

9)Remake initrd for the kernel (So the radeon module is not force loaded)

mkinitrd  /boot/initrd-`uname -r`.img `uname -r`

10) Prevent libdrm from being upgraded 

perl -i -pe "s/([.*])/1nexclude=libdrm/"  /etc/yum.repos.d/fedora.repo
perl -i -pe "s/([.*])/1nexclude=libdrm/" /etc/yum.repos.d/fedora-updates.repo

11)Open 

/boot/grub/grub.conf in root mode

Go to

kernel

line and add

vga=0xmode

mode for me was

323

which was 1024×768 32 bit

12)Edit /etc/modprobe.d/blacklist

Add radeon

13)Reboot and Voila !!

VlC , KAFFEINE , REALPLAYER Problems Fedora 10

Leave a comment

Well Just as Fedora 9 , Fedora 10 media players couldn’t play my videos by default.

1)VLC(only for below 0.9+):

1) Go to Settings>Preferences>Check Advanced Options
2)Audio>Output Modules>Select ALSA Audio output >ALSA>Refresh List>Select Device
3)Video>Output modules>Select X11 Video Output

2)KAFFEINE:

1)Settings>Xine Engine Parameters>Video>Select Beginner Options

2) Select xv or xshm (Previously xshm used to work now xv does)

3) REAL PLAYER:

Tools>Preferences>Hardware

For me Alsa couldn’t be initialized. Hence RealPlayer 11 can be used on OSS. (You may have to disable XVvideo)

Fedora 10

Wifi in Fedora 10 (broadcom wl)

3 Comments

To make them work you have 2 ways:

1)Install Ndiswrapper

or

2)Install Broadcom Driver for linux

Faster is the Broadcom route so here goes:–

You need to install these packages either through package manager or download them seperately from

http://download1.rpmfusion.org/nonfree/fedora/releases/10/Everything/i386/os/

and use rpm -ivh <name>  (Remember: ALT+F2>gnome-terminal>su – >then yum install <name> or rpm -ivh <name>)

kmod-wl-*

broadcom-wl-*

* means all packages for your kernel version and architecture
to find kernel version uname -r

3)Open /etc/sysconfig/network-scripts/ifcfg-wlan0 (assuming wlan0 is the wireless interface)

change ONBOOT=off to ONBOOT=on

Fedora 10

Fedora 10 Cambridge Essentials Guide Part 2: More Config

2 Comments

NOTE:All Commands to be entered in terminal in Super User/root mode. (.:. su – or sudo)

1) Setup sudo
In Fedora the root and normal user accounts are different and one can switch between them to do administrative tasks.
However if you want to give a user other than root administrative priviliges

nano /etc/sudoers

Add to the end

<name> ALL=(ALL) ALL

is the user name you want to give sudo privilige.

<name> ALL=(ALL) NOPASSWD: ALL

if you dont want to be asked the password .(NOT RECOMMENDED)

2)Permanantly Mounting Partitions:

Fedora 10 has ntfs 3g preinstalled but sometimes the partitions don’t get mounted (or you just may want to get rid of manual mounting)

Editing fstab gives read/write support on boot

a) use fdisk : /sbin/fdisk -l

b) note down partions u wnt to access name (eg sda1) type (eg ntfs or FAT32)

c)Make mount points:

mkdir /media/<name>
<name>can be replaced by whatever name you choose.

d)open gedit in sudo mode

e)Open /etc/fstab

f)For ntfs drive ( mount point here is DATA)

   /dev/sda1 /media/DATA ntfs-3g rw,defaults,umask=0000 0 0
or /dev/sda1 /media/DATA ntfs-3g defaults 0 0

if drive is FAT32/FAT16 use vfat instead of ntfs-3g , other lines are NOT REQUIRED

3)Macromedia Flash :

For 32 bit:

install the Adobe YUM repository, and install through yum:

rpm -ivh http://linuxdownload.adobe.com/adobe-release/adobe-release-i386-1.0-1.noarch.rpm
rpm –import /etc/pki/rpm-gpg/RPM-GPG-KEY-adobe-linux

yum install flash-plugin (if you dont do this no sound for flash applicatons)
For 64 bit:

There are 2 ways.

OLDER WAY:

mkdir -p /usr/lib/mozilla/plugins
yum install nspluginwrapper.{i386,x86_64} pulseaud/io-lib.i386
yum install flash-plugin
mozilla-plugin-config -i -g -v

NEWER WAY:

Download 64 bit Flash Player 10 (currently alhpa stage)
http://labs.adobe.com/downloads/flashplayer10.html

4) Installing Sun Java

a) Download JDK from http://java.sun.com/javase/downloads
To install rpm
rpm -ivh .rpm
To install bin
chmox +x .bin
./.bin

/usr/sbin/alternatives --install /usr/bin/java java /usr/java/jre/bin/java 100
/usr/sbin/alternatives --install /usr/bin/jar jar /usr/java/jre/bin/jar 100
/usr/sbin/alternatives --install /usr/bin/javavc javavc /usr/java/jre/bin/javavc 100
/usr/sbin/alternatives --install /usr/lib/mozilla/plugins/libjavaplugin.so 100

b) To use Switch among javas:
/usr/sbin/alternatives --config java
/usr/sbin/alternatives --config libjavaplugin.so
/usr/sbin/alternatives --config jar

c)For Java Programs(You Probably Already Have This):
yum install libXp compat-libstdc++-*

Fedora 10 Cambridge essentials guide

Well Howdy Folks ! ,thou having trouble with getting Fedora 10 Cambridge Up and Running ?

Well then you have come to the right place !!!
NOTE:all commands r to be typed in terminal with sudo or su login or su -c
PS: All yum commands can be replaced by package kit alternatives type “info pkcon” in terminal.

1)RPM-FUSION:Adding rpmfusion as a repository to get access to lot of other packages and features.

(VERY ESSENTIAL ALL OTHER STEPS REQUIRE THIS)

rpm -ivh http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm  http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm

yum update

To install something in command line use

yum install Name of Packages Seperated by spaces -y

of course to find the exact package name use

yum search Package


2)Package Management Frontend GUI :

Fedora already has PackageKit (System>Administration>Add/Remove Software)

but it doesn’t quite compare up to yumex

yum install yumex

3)MP3 Support:

Well, everybody loves their songs right ?

yum install gstreamer-plugins-ugly gstreamer-plugins-bad gstreamer-plugins-good gstreamer-plugins-pulse libmad libid3tag xine-lib-extras xine-lib-extras-freeworld


4)Music Players:

Everybody has a different choice of a music player , I personally prefer Amarok which has everything from cover management ,id3tag editing,online Music Store Support and Global key Shortcuts.

Few of the most used players.

                     -Amarok
                     -Audacious
                     -Banshee
                     -Exaile
                     -Listen
                     -Rhythmbox
                     -Xmms

4)GCC compatibility:

GCC is the GNU compiler supporting a lot of languages.Its needed for

yum install gcc gcc-c++ compat-libstdc++-33 compat-libstdc++-296

5)Video Codecs:

Fedora doesn’t with proprietary codecs for playing Codecs.

Download them.

wget  http://www.mplayerhq.hu/MPlayer/releases/codecs/all-20071007.tar.bz2

then

mkdir -p /usr/lib/codecs

tar -jxvf all-20071007.tar.bz2 --strip-components 1 -C /usr/lib/codecs/

5)Video Players:

Totem is installed by default but its not a favourite of mine.

Real Player

Download RealPlayer 11 GOLD from: http://www.real.com/linux/. ( preferably use .bin file)

Select: “Advanced Installation RedHat Package”

Before installing RealPlayer, make sure to have the compat-libstdc++-33 compatibility libraries installed.
yum install compat-libstdc++-33

chmod +x name.bin

./name.bin

Read Agreement Go to end and press y and enter (keep pressing enter, till it starts installing)

For RPM:
sudo rpm -ivh RealPlayer11.rpm

note:if real/helix or any plugin doesnt load in firefox use:
sudo /usr/bin/mozilla-plugin-config -i -f

Other Players

mplayer: yum install mplayer mplayer-gui mplayer-skins mplayer-fonts mplayerplug-in mencoder
xine:       yum install xine xine-lib-extras xine-lib-extras-nonfree libdvdcss
vlc:         yum install vlc

kaffeine yum install kaffeine kdemultimedia kdemultimedia-libs

Dragon : yum install dragon kdemultimedia kdemultimedia-libs

Note: After this if it doesn’t work refer to my other posts

Using Mandriva 2009 , GeexBox 1.2 beta

1 Comment

I think its a kernel issue with 2.6.27 that acpi is switched on unsupported bios models.

Hence In Mandirva 2009

boot to live cd Press F3 then F4 select acpi=off. (Or the system will crawl)

If you are not able to get a GUI boot like me then ..

1)login with username  root

2)run drakX11 then configure various your graphics card and Resolution (Dont forget to use the ‘Test’ option)

(For ATI x1250 use fglrx (faster) or radeonhd (slower))

3) After install  edit /boot/grub/menu.lst

and add acpi=off to your options in kernel line if ts not there already

GeexBox 1.2 beta

Same story

While booting press ‘TAB’ add acpi=off in kernel line.

Currently HDMode doesn’t work with many Graphics Cards like ATI x1250 (again xorg issues)

so Start in non HD mode only.

Intrepid Ibex comes with the Broadcom STA driver which has wl.ko module but ssb and b43 modules r loaded..

Add folowing lines to /etc/modprobe.d/blacklist

blacklist ssb

blacklist b43

Reboot and check if your wifi is working or not .

If not (and the modules still got loaded into memory)

delete following modules

/lib/modules/’uname -r ‘/kernel/drivers/ssb/ssb.ko

and

/lib/modules/’uname -r ‘/kernel/drivers/net/wireless/b43/b43.ko
