Using Open Source Methods in a Private Company

Let’s say your business doesn’t have one bit of interest in sharing its internal code with the outside world. Does that mean that open source methods of programming can’t do you any good? Camille Fournier, Director of Engineering for retailer Rent the Runway, Apache ZooKeeper committer, and former Goldman Sachs VP, believes adopting open source software development methods can help even your organization.

At OSCon, the major open source convention in Portland, OR, Fournier opened her session, “Internal Open Source: Running internal projects with open source methods,” by observing that while “open source software is everywhere,” not all companies have adopted it.

“Most companies, big and small, have some code that is shared by many but owned by few. It may be in the form of useful libraries for common tasks like logging and configuration. It may be in the form of internal services that cross business functions,” she said. “Managing these libraries and services often falls onto the teams that originally created them, or on a core tech team that owns all shared software. This model has many drawbacks: slow changes, a lack of transparency for users, and a tendency to cause bottlenecks for other developers.”

Big data, metadata, and traffic analysis: What the NSA is really doing

What I find most remarkable about all the hubbub about the National Security Agency’s Prism program is how little new “news” there is to Edward Snowden’s “revelations.”

After all, the NSA’s mission has been to intercept communications and break codes ever since it was founded in 1952. Combine that with the Patriot Act, and anyone who’s bothered to read the books of NSA expert James Bamford over the last few years won’t find anything in the least bit surprising about Prism.

It’s possible, of course, that the NSA is doing something technically interesting, like intercepting and breaking SSL-protected Internet communications. But the NSA doesn’t have to bother with deciphering your PGP-protected love notes to your sweetie to know what you’re up to. No, they can combine their age old techniques of working with metadata and traffic analysis with 21st century big data analysis to have a darn good idea of what you, along with everyone else, are doing.

It’s not just the NSA, though. Big Internet businesses have been using the same techniques to deliver customized Web experiences to you for almost twenty years.
