Getting VLC or x264 source code via Git
$ git clone git://git.videolan.org/vlc.git

The image shows an error which says, google-chrome-beta is conflicting package, so what is upgrade?

Google Chrome is stable true, but when will GNU/Linux users get Google's chat client? Do we really need it!

Notes:

Logic:

1. Checking if the host is alive.
2. Getting info about them, via remote commands.

Steps:

1. Prepare password free SSH access.
2. Make a simple script to get host info.

Surfraw provides a fast unix command line interface to a variety of popular WWW search engines and other artifacts of power.It reclaims google, altavista, dejanews,freshmeat, research index, slashdot and many others from the false‐prophet, pox‐infested heathen lands of html‐forms, placing these wonders where they belong, deep in unix heartland, as god loving extensions to the shell.

The flow of embedding a wave to any webpage

The URI will be like : google_wave_domain#Postion!w[Code]

The embed code will be:

DIV => id="waveframe" style="width: 500px; height: 500px"

JavaScript:

google.load("wave", "1");
google.setOnLoadCallback(initialize);
function initialize() {
var waveframe = document.getElementById("waveframe");
var embedOptions = {
target: waveframe,
header: true,
toolbar: true,
footer: true
};

Sample WAVES embedded

The idea was to make a desktop application for GNU/Linux where you could make searching Request for Comments (RFC), easier and full, later one the idea is to make a panel app to do the same.
As a open source and free software under GNU GPLV3, indeed the power is of the open source world is 'you' can contribute and help it to improve.

Status report form From: Richard Guenther

Status
=======
The GCC 4.5.0 release has been created and the branch is now open for regression and documentation fixes again.The release will be announced once the upload to ftp.gnu.org finished and the mirrors had a chance to catch up.

Most of us would have attended many conferences and seminars, with an agenda a topic too and yes indeed lunch and back home, but it was a year back when i read the mail which said , "Come, join this innovative unconference session anchored by IBM developerWorks. Because You Matter. ", it was called Unconference!

Wondering what an Unconference is i asked Mr.Google who had then returned an IBM link to the same event!
But today there are many links, wikis and many other social networking updates on the same, the same is making it clear what impact does an Unconference can have.

Go is a compiled, garbage-collected, concurrent programming language developed by Google Inc.

Below is a simple script to intsall it:

There are many ways to achieve the same, after meddling with different ways and from the help of few ruby clans, I could decide upon the most reliable and the best way to achieve this as below.

Logic:
Given a length 'len', here its 6 generate a series of unique random strings. Makes use of rand() with max value as 36^@len -1
As [a-z] and [0-9] makes 36 chars and to_s(base=10) along with a simple right justification rjust()

From docs :

rand(max=0) => number

Converts max to an integer using max1 = max.to_i.abs. If the result is zero, returns a pseudorandom floating point number greater than or equal to 0.0 and less than 1.0. Otherwise, returns a pseudorandom integer greater than or equal to zero and less than max1. Kernel::srand may be used to ensure repeatable sequences of random numbers between different runs of the program. Ruby currently uses a modified Mersenne Twister with a period of 2**19937-1.

to_s()

fix.to_s( base=10 ) → aString

Returns a string containing the representation of fix radix base (between 2 and 36).

rjust()

str.rjust(integer, padstr=' ') => new_str

If integer is greater than the length of str, returns a new String of length integer with str right justified and padded with padstr; otherwise, returns str.

    end while @generated.member? rstr
 
    @generated << rstr
 
    rstr

end
 
if $0 == __FILE__

Customizing Bespin with syntax and code highlighting
Read the intro to bespin before you continue
Prereq:
Python 2.5 with simplejson or Python 2.6

Peek into dryice.py :

#!/usr/bin/env python
# Simple script to run dryice conveniently in the Customizable package
import sys
import os
mydir = os.path.dirname(__file__)
sys.path.insert(0, os.path.join(mydir, "lib"))
from dryice import tool
tool.main()

Sample json {manifest} :

"Bespin is a Mozilla Labs experiment on how to build an extensible Web code editor using HTML 5 technology."

To install The Network Simulator - ns-2 we need to bit of circus.

Install dependencies :
$ sudo apt-get install libpcap-dev gcc-4.3 g++-4.3 tcl  tk  tk8.4-dev tcl8.4-dev xorg-dev sgb

By default gcc version is 4.4, but has ns2 compiles well only will 4.3 we need to downgrade gcc !

Backup the current links and update symbolic links :

$ sudo mv gcc gcc.old
$ sudo mv i486-linux-gnu-gcc i486-linux-gnu-gcc.old 
$ sudo ln -s gcc-4.3 gcc 
$ sudo ln -s gcc-4.3 i486-linux-gnu-gcc 

Download and Install ns2:

My 55 ideas for Google Wave :{Some are on it's way} :
Go and vote here : You liked any?

1."Alloww grouping in contacts list like Friends,Co-workers,Bots so on. So when i click on Friends all of them in that group must be added to a single wave, so we need not add each of them."

2."Block/Ban/Kick users, sometimes spammers or sometimes from contact list itself!"

3."Ability to drag and drop media from hard-disk to wave"

As the latest firfox came up was were happy to read the below in there site :

"Currently, an entirely new spec is being drafted for file objects and handling within HTML5. It will provide a much more robust interface for accessing content in local files, in addition to extending functionality for file objects within Javascript/DOM. The primary additions include:

* Drag n' drop of local files into a web page.
* Asynchronous file data access via callback methods.
* Sending file objects via XMLHttpRequest.

DB replication/reflection is on the most import process while achieving a distributed system, which helps in the DB synchronization between remote hosts.

The concept is pretty simple :

1.Setting up the Master.

2.Setting up the Slave.

3.Let the Slave receive events from master and update DB.

Creating a read-only mirror of a repository from a HTTPS which is in sync helps to maintain an local repo which is in sync with the global and is much faster and reliable for a group working locally.
Achieving this is pretty simple,svnsync - Subversion repository synchronization tool which makes the job easier.

The idea is pretty simple, the steps followed are :

1.Setting up a mirror repository.
2.Initialize (init) the sync.
3.Synchronizing the data.
4.Making a sync job.

Setting up a mirror repository:

#Create a mirror repository

Simple but effective and handy utility for people dealing with hell lot of zips.

# Test if the program is installed 
   type -P $1 &>/dev/null || echo $1 not installed! ; exit 1;
# Try to extract 
  Switch for the appropriate case.
