History of Open Source Coding and the Open Cloud

SHOW ME GHe Source: Open source THE EVOLUGION OF Fİrst the basics: WHab CkactLY IS Gource CODE? All computer programs that you run are actually files that contain nothing more than machine code, which looks like jibberish to humans. However computer programmers do not actually write in machine code. They write in any of the many available computer languages like C++, BASIC, Java, etc. When the program is completed, it is translated by software called "compilers" into the executable machine code. Software developers can't tell how a program was written simply by looking at or running the machine code, so companies can distribute their software to the entire world while keeping the actual source code secret. Source Code (in C): #include "stdio.h" int main() { EXAMPLE OF SOURCE CODE printf("Hello World!n"); return (0); what is open source? Open Source is the phrase used to describe the act of freely sharing the source code of a computer program with the world. The term "open source" gained recognition at the 1998 O'Reilly's Free Software Summit as replacement for the commonly used term "free software" (or "freeware"). open source isn't new. Source code has a lot of corollaries outside the realm of computer programs. Cooking recipes are a kind of source code, as are blueprints, as are manufacturing instructions. You can have secret recipes just as you can have secret computer code. There are reasons to keep recipes secret, just as there are opposing reasons to publish cookbooks. At its heart, Open Source is the idea of sharing plans, methods, instructions, and intellectual property. open source or closed source? CLOSED SOURCE A company has the right to hold on to a formula they created so that they can recoup the cost of development and make a profit. Drug companies invest millions of dollars to perfect a new medication and when they finally find the formula that works, they alone have the legal right to make it without releasing the formula for three years. After that, we see the cost plummet as KEEP OUT! other manufacturers access the formula to make generic versions. OPEN SOURCE Making money from the recipe is a secondary motive in open source. Most of the money in open source |Come in We're comes from companies providing services and support or asking for donations from happy users. Open source projects rely on the brainpower of the community by inviting collaborators to help perfect software. As a result, open source software can OPEN sidestep some of the problems that arise in closed source projects, like lack of resources and corporate constraints. open source helped win WWII! After the Pearl Harbor attack, the Automotive Council for War TWO FRONT Production was formed, bringing together 654 manufacturing companies. What did pooling these resources accomplish? • Cut the time to produce a British ack-ack gun by 4 months • Cut the 3.5 hour process of broaching the barrel operation down to 15 minutes HOME-FRONT DUTIES JOB • Cut automatic cannon costs from $1200 to $600 in 18 months • Cut production time on tank-engine sprockets from 8 hours to 6 minutes MOTOR TRUCKSs AUTOMOTIVE COUNCIL CARRY ON COMBAT and FOR WAR PRODUCTION OPen source in a can! OPENCOLA Like software, many consumer products are made with proprietary recipes that aren't available to the public. Coca-cola has a closely guarded blend - a closed source. OpenCola, on the other hand, publishes its blend allowing users to modify and improve it. opencola open source standouts The open or closed nature of a product typically goes unnoticed to average users. Many closed-source applications have popular open source equivalents and many applications we use daily are open source. LINUX Facebook, Twitter, and Google all use Linux to handle billions of users. The New York Stock Exchange, Tokyo Stock Exchange, London Stock Exchange and Chicago Mercantil Exchange all use Linux. In fact, over 75% (trillions of dollars) of all equities are exchanged on Linux. WORDPRESS This open source blogging platform is used by over 13% of the 1,000,000 biggest websites from personal blogs to WORDPRESs Fortune 500 websites including, the UPS Blog, PlayStation blog, and the Rackspace Blog. MOZILLA FIREFOX Built by the Mozilla to improve the way people experience the Internet, Firefox has become the second most widely used Internet Web browser at 30% of worldwide usage in less than ten years. ANDROID The open-source software stack for mobile devices enjoys 17.2% worldwide market share of smartphones and an estimated 400,000 new devices activated daily. CIOECUD who uses open source? in 2010, approximately 98% of enterprise-grade organizations use open source. Google facebook. twitter to the Future: OPen cloud From recipes in cookbooks, to wartime mobilization, to software, the open source philosophy continues to thrive with projects like these that combine cloud technologies with the spirit of openness: The Spirit of Openness Anyone can build their own cloud with OpenStack - a collection of open source technologies delivering a massively scalable cloud operating system thanks to the collaborative efforts of Rackspace, NASA, openstack and approximately 50 other contributing members. Facebook has one of the most efficient datacenters in the world full of vanity-free servers. These servers are 38% more OPEN Compute Project efficient and 24% less expensive to build and run than other state-of-the-art data centers. And, they're sharing it so others can implement it in their own businesses and suggest improvements. VMware just released the project Cloud Foundry, the world's first open Platform as a Service (PaaS) offering. Cloud Foundry provides a platform for building, deploying, and running cloud apps using Spring for Java developers, Rails and Sinatra for Ruby developers, Node.js and other JVM frameworks including Grails.
