What Is Open Source?

The Linux penguin.

Entrepreneurs, especially those outside of software development, may find this article useful.

When Performance Matters

Over seventy percent of the web servers on the planet run Linux, the open source operating system. Google, Facebook, and Amazon all run Linux. They bet their companies on this decision every day.

Given that thousands of successful companies have bet their livelihood on open source, an observer might ask these questions:

  • What is open source?
  • Why should one care about open source?
  • How can a company profit from software that is given away for free?

SGI & Big Data

SGI's logo from the 1990s.

Silicon Graphics International Corporation (SGI) computers rendered the special effects for the original Jurassic Park movie. Computer enthusiasts coveted SGI machines throughout the 1990s.

But success in the computer industry is fleeting. A few years after Jurassic Park, a convergence of tech advances (Moore’s Law, x86 architecture, and Linux) made it possible for commodity PCs to perform as well as SGI’s premium workstations. Wall Street traders and other power users abandoned workstations in favor of Linux-based PCs. High-end makers like SGI fell on hard times.

Today, SGI is fighting back. The company is blending x86, Linux, and (buzzword alert) big data to attack the high performance computing market. The vision was presented at this month’s Chicago ACM meeting by Brian Freed, VP of Strategy for SGI.

Homebrew Fundamentals

Spend enough time developing software on Mac OS X, and you will eventually need to install libraries that were written for Unix, but not specifically for OS X. Fortunately we have Homebrew, which makes it easier to install Unix libraries on the Mac.

Why Homebrew?

Before installing any new software, it is helpful to have a clear view of why we need it.

Homebrew is a package manager. It differs from earlier package managers like Fink and MacPorts because it is written in Ruby and based on Git. The Ruby/Git foundation means that developers from around the planet can easily contribute to Homebrew’s growth.

Before package managers, developers who needed a particular library would have to:

  • Manually download source code for the library.
  • Manually compile using gcc or another compiler.
  • Resolve dependencies manually.

Manually, manually, manually… The old way was long and error-prone. Max Howell created Homebrew to download, compile, and resolve dependencies automatically. Now developers can focus more attention on solving problems that are directly related to their work.

Installing Rubinius Using RVM

Rubinius is an implementation of the Ruby language designed for concurrency. The lead developer of Rubinius, Brian Shirai, will present Rubinius at ChicagoRuby on March 4, 2014. ChicagoRuby will follow-up with a Rubinius-themed hack night on March 12th. Details.

To prepare for the Rubinius events, some people may choose to install Rubinius locally. RVM makes the process smooth.
