This is not done for the love of humanity. Walmart takes the effort to work in the open because there is a return to be had from that investment. When other companies adopt Hapi, Walmart expects their internal implementations will lead them to improve the code to better suit their needs. Since the majority of these improvements are likely to be integral to the code in the commons, any rational actor will make pull requests attempting to have their work integrated in the project trunk.
Of course -- otherwise, the team making the changes would be eternally burdened with the need to refactor and test their changes each time the trunk is updated. Successful pull requests lead to merges that bring the whole community together for the upkeep of the code, not just the developers who originally wrote it.
In a nutshell, IoT is about using smart devices to collect data that is transmitted via the Internet to other devices. It's closely related to machine-to-machine (M2M) technology. While the concept had been around for some time, the term "Internet of Things" was first used in 1999 by Kevin Ashton, who was a Procter & Gamble employee at the time.
While the open source approach to software development has proven its value over and over again, the idea of opening up the code for security features to anyone with eyeballs still creates anxiety in some circles. Such worries are ill-founded, though.
One concern about opening up security code to anyone is that anyone will include the NSA, which has a habit of discovering vulnerabilities and sitting on them so it can exploit them at a later time. Such discoveries shouldn't be a cause of concern, argued Phil Zimmermann, creator of PGP, the encryption scheme Yahoo and Google will be using for their webmail.
The logic is understandable - how can a software with source code that can easily be viewed, accessed and changed have even a modicum of security?
Open source software is safer than many believe.
But with organizations around the globe deploying open source solutions in even some of the most mission-critical and security-sensitive environments, there is clearly something unaccounted for by that logic. According to a November 28 2013 Financial News article, some of the world's largest banks and exchanges, including Deutsche Bank and the New York Stock Exchange, have been active in open source projects and are operating their infrastructure on Linux, Apache and similar systems.
Greg Avola loves beer and coding. He loves beer so much that he made an app, Untappd, where users track their favorite brews. He loves coding so much that he wrote a book about mobile web development. According to him, if it weren't for open source software, his app—and the projects of many other developers—simply wouldn't exist.
Read more in my interview with Greg about his open source journey, his favorite beer, and why check-in apps are still relevant.
Docker has quickly become one of the most popular open source projects in cloud computing. With millions of Docker Engine downloads, hundreds of meetup groups in 40 countries and dozens upon dozens of companies announcing Docker integration, it's no wonder the less-than-two-year-old project ranked No. 2 overall behind OpenStack in Linux.com and The New Stack's top open cloud project survey.
This meteoric rise is still puzzling, and somewhat problematic, however, for Docker, which is “just trying to keep up” with all of the attention and contributions it's receiving, said founder Solomon Hykes in his keynote at LinuxCon and CloudOpen on Thursday. Most people today who are aware of Docker don't necessarily understand how it works or even why it exists, he said, because they haven't actually used it.
“Docker is very popular, it became popular very fast, and we're not really sure why,” Hykes said. “My personal theory … is that it was in the right place at the right time for a trend that's much bigger than Docker, and that is very important for all of us, that has to do with how applications are built.”
