Linux, Wikinomics and Mining the Gold!
Currently I am reading a book titled Wikinomics. This book is all about how web2.0 have changed the way we do business and how collaborative models are proving to be successful against those of conventional and closed approaches of doing businesses.
Very first chapter of the book starts with an impressive example of Goldcorp a gold mining comapny. It is simply more optimistic piece about the power of mass human collaboration to solve problems. It is interesting not only because it is about Goldcorp, but also because it is about a leader willing to take a big risk and put faith in the collective intelligence of the crowd.
You may get confused that what Linux has to do with Gold mining and why I am writing this blog entry in joyoflinux blog but let me uncover the blanket. The story goes like this:
It’s the year 2000 and the CEO of Goldcorp Inc., a gold producer headquartered in Vancouver, Canada was concerned about an underperforming mine in Ontario. The company’s Red Lake mine was only producing a relatively small 50,000 ounces of gold a year at a high cost of $360 an ounce. The main deposits were deeper underground, but his company’s geologists were not sure of the exact location of the precious metal.
Goldcorp was in trouble. Besieged by strikes, lingering debts, and an exceedingly high cost of production, the company had terminated mining operations. Conditions in the marketplace were hardly favorable. The gold market was contracting, and most analysts assumed that the company’s fifty-year old mine in Red Lake, Ontario, was dying. Without evidence of substantial new gold deposits, Goldcorp was likely to fold.
McEwen wanted new ideas of where to dig and he figured that if his Red Lake employees couldn’t find the gold then someone else would be able to.
McEwen Finds a way too simple but too hard to implement!
McEwen was not a miner, nor did he come from a mining background. Before being bitten by the gold bug he worked in the investment business for Merrill Lynch. And so he did not feel constrained to adopt conventional mining wisdom. Not having grown up with the assumptions of the industry he felt able to question them. Confidentiality and secrecy are industry watchwords and yet here was the CEO apparently giving away the family jewels.
The trigger for solution to his problem was an MIT conference he had attended in 1999. The story of Linus Torvalds came up and how he used the Internet as a collaborative resource to build the Linux software operating system. It fired up his imagination and he headed back to company headquarters full of ideas which culminated with the Goldcorp Challenge.
Gold Rush
So he triggered a new gold rush by issuing an extraordinary challenge. He put all his company’s geological data (which went back as far as 1948) into a file and shared it with the whole world. McEwen hoped that outside experts would tell him where to find the next six million ounces of gold. In return he offered $575,000 in prizes to the participants with the best methods.
Unsurprisingly his colleagues were skeptical, particularly as it was such a risky venture. The company was, after all, giving over its proprietary data as well as admitting to the industry that they were unable to find these elusive gold deposits.
The Goldcorp Challenge was launched in March 2000 and 400 megabytes worth of data about the 55,000 acre site was placed on the company’s website. Everything that the company new about the Red Lake mine was a mouse click away. Word spread fast around the Internet and within a few weeks submissions came in from all over the world as more than 1,000 virtual prospectors chewed over the data.
Some were from geologists, but many were from individuals in unrelated sectors. There were mathematicians, military officers, students, and consultants. The top winning entry was a collaborative effort by two groups from Australia. From the opposite end of the Earth and without having ever visited that part of Canada Fractal Graphics, in West Perth, and Taylor Wall & Associates, in Queensland developed a 3-D map of the mine. It included powerful computer graphics that allowed McEwen and his geologists to see the potential in Red Lake.
Goldcorp Challenge was a Goldmine
In all more than 110 sites were identified and 50% of these were previously unknown to the company. Of these new targets, more than 80 per cent yielded significant gold reserves. McEwen believes that this collaborative process cut two, maybe three years off the company’s exploration time. And the worth of this gold has so far exceeded $6 billion in value. The prize money was only a little over half a million dollars, so it was a fantastic value for money investment, and much cheaper than continuing with unproductive exploratory drilling.
By going outside his company’s walls McEwen turned Goldcorp from a struggling enterprise into one of the most profitable in the industry.

The watch command executes another command periodically, in this case “cat /proc/interrups”. The -n1 option tells watch to execute the command every second.
Linux: Designed for the Cloud
Linux: Designed for the Cloud
Linux is the natural technology for enabling cloud computing: it’s modular, it’s performant, it’s power efficient, it scales, it’s open source, and it’s ubiquitous. And, as the platform upon which the largest cloud infrastructures, in the world have been built, Linux – unlike other available operating systems – has little left to prove as a component of cloud infrastructures be they public or private. “Every time you use Google, you’re using a machine running the Linux kernel,” as Google’s Chris DiBona has said.
Following are cloud computing products powered by Linux.

How to change root password in Linux
This is one of the problem faced by many person’s“what if i lost the root password”First thing that comes in mind is “use single user mode” but the answer is NO.
So the BIG QUESTION IS HOW TO proceed further
follow these steps
1) on grub-boot prompt. press “e” to enter edit mode
2) then press downarrow to reach the line that starts with “kernel “ press “e” again
3) at the end of this line type in “init=/bin/sh” or “/bin/bash”
4) then press enter to make that change and press “b” to boot in a few seconds you will be on your “#” prompt
5) only one step left “mount -o remount rw /”
this step is necessary coz in this case root file system is mounted as read only.
6) finally type “passwd” and you get the screen to change the password
and then type in “init 6″ or “reboot”
NOTE FOR TECHNICAL USERS
those who are looking for the technical details, the main work is the init command that we passed as an argument to kernel, it told kernel to specifically run the command specified in parameter instead of working on normal routine.
TRICK = if you have any program you wish to run instead of this then you can do that too using init command only.
Netbooks, based on Ubuntu
Canonical, the commercial sponsor of Ubuntu, on June 3, 2008 announced that it will be demonstrating a reworked desktop image of Ubuntu built specifically for a new category of portable Internet-centric devices – netbooks. These affordable, power-efficient, small screen devices, based on the ground breaking low-power micro-architecture of the Intel® Atom™ processor, and Ubuntu allow consumers to enjoy email, instant messaging, Internet surfing and on-line access to photos, videos or music with an affordable, reliable device.
Ubuntu Netbook Remix leverages Moblin technologies optimized for the Intel Atom processor. Intel and Canonical are working to create a next generation computing experience across a new category of affordable Internet-centric, portable devices; including Mobile Internet Devices (MIDs), netbooks, nettops and embedded devices based on Intel Atom processor technology. Canonical is a founding contributor to Moblin and will continue to work with Intel to ensure the best open source applications become available to users and OEMs through Moblin.
Goosh – the Google Shell
It’s an ever-continuing debate: what is better, a graphical user interface, or a command-line interface? Graphical user interfaces may be easier to learn, but complicated operations may require a lot more user input than with a command line interface, which can perform several complicated operations by using a short sequence of words and characters. However, a CLI has a much steeper learning curve than a GUI. Google has always had a certain CLI-quality to it, and Stefan Grothkopp decided to take this a few steps further: say hello to Goosh.
Goosh, the Google Shell, is a command-line interface of the many functions Google provides, allowing you to do all sorts of cool things. For instance, translate nl en “lang leve de CLI!” will translate said sentence from Dutch (Netherlandic, “nl”) to English. See the image below to get an idea.
goosh. It’s essentially a browser-oriented, shell-like interface that allows you to quickly search Google (and images and news) and Wikipedia and get information in a text-only format. This is quite possibly the coolest thing I’ve seen in a good while.”
Quick look at goosh
Installing Ruby in Ubuntu 8.04
Today I have started learning ruby and was really curious of how to install it on GNU/linux as I am newly wed with Ubuntu. Recently I divorced with Fedora and decided to happily live with Ubuntu.
So I can’t believe that it may be so simple.
Just one command sudo apt-get install ruby
And if your repository settings are upto date and if your system is well configured then here it goes.
It took just one minute to configure everything
Here is console output.

BBC interviewed Mark Shuttleworth
I think almost every linux user knows about mark shuttleworth. He is founder of canonical foundation and above all he is founder of Ubuntu Linux Operating System. Ubuntu have created win-win situation in desktop market and is rocking day by day.
More importantly Mark is among those people who are non-astronauts and traveled in space.

So here is the link of the interview taken by BBC.
It’s really inspiring.
