Software

Kernel

Get Fedora 12 kernels
Change the default kernel in the system's boot loader configuration.
/etc/sysconfig/kernel: 
UPGRADEDEFAULT - Controls whether new kernels will be booted by default (default value: yes)
DEFAULTKERNEL - kernel RPMs whose names match this value will be booted by default 
                (default value: depends on hardware configuration)
Build kernel: 
1. Obtain the kernel-<version>.src.rpm  file
	i.e: up2date --get-source kernel
2. Install kernel-<version>.src.rpm
	default to /usr/src/redhat/
3. Change directory to /usr/src/redhat/SPECS/, and issue the following command:
	rpmbuild -bp --target=i686 kernel-<version>.spec
	or
	rpmbuild -bp --target=x86_64 kernel-<version>.spec
	On a default RPM configuration, the kernel tree will be located in
	/usr/src/redhat/BUILD/.
4. In resulting tree, the configurations in the /configs/ directory.
	Place the desired configuration in the proper place for building:
	cp <desired-file>  ./.config
5. Issue the following command:
	make menuconfig
You can then proceed as usual.

Firefox

Setup

Here's something for broadband people that will really speed Firefox up:
1.Type "about:config" into the address bar and hit return. Scroll down and look for the following entries:

network.http.pipelining network.http.proxy.pipelining
network.http.pipelining.maxrequests

Normally the browser will make one request to a web page at a time. When you enable pipelining it will make several at once, which really speeds up page loading.

2. Alter the entries as follows:

Set "network.http.pipelining" to "true"

Set "network.http.proxy.pipelining" to "true"

Set "network.http.pipelining.maxrequests" to some number like 30. This means it will make 30 requests at once.

3. Lastly right-click anywhere and select New-> Integer. Name it "nglayout.initialpaint.delay" and set its value to "0". This value is the amount of time the browser waits before it acts on information it receives.

If you're using a broadband connection you'll load pages MUCH faster now!

Linux Plugins

On 64bit systems: 
yum install nspluginwrapper.i686  # or: yum install nspluginwrapper.i386
# nspluginwrapper.x86_64 is not enough !!!
Firefox & Konquerror plugins:
/usr/lib/mozilla/plugins
# /var/lib/firefox-ver/plugins/
After installing new plugins from Konquerror: rescan new plugins
PluginDoc

Adobe Flash Player

Get .tar.gz for Linux (x86) 
$ cp libflashplayer.so /usr/lib/mozilla/plugins

RealPlayer 10 for Linux

Get
Helix Community Helix Player project 
$ rpm -i RealPlayer10GOLD.rpm
$ cd /usr/local/RealPlayer
$ ./realplay
This make link "/usr/bin/realplay"
Test: LR 1, LR 2

Java Runtime Environment

Sun JRE 5.0
  1. Install Java Runtime Environment.
  2. Make a symbolic link to libjavaplugin_oji.so in your Mozilla Plugins directory. Unless you are using an old version of Mozilla, or one you compiled yourself with gcc 2.9x, use the copy located in the plugin/i386/ns7 directory of JRE 5.0, or plugin/i386/ns610-gcc32 if you are using JRE 1.4.2.
Note: java usually installs in /usr/java/ 
# var šādi:
$ ln -s /usr/java/jre1.5.0_06/plugin/i386/ns7/libjavaplugin_oji.so 
        /usr/lib/firefox-1.0/plugins/libjavaplugin_oji.so
        
# labaak (universālāk):
$ ln -s /usr/java/jre1.5.0_06/plugin/i386/ns7/libjavaplugin_oji.so 
	/usr/lib/mozilla/plugins/libjavaplugin_oji.so
For comand line java support edit /etc/profile 
pathmunge /usr/java/jre1.5.0_03/bin after
