In my latest article for Linux Journal, I explain the process by showing you how to build a web application for tracking books you’ve… Read More »
Every once in a while, I come across a concept that strikes me as a game-changer, and Kubermesh is one. The idea, put into action by the folks at Ocado Technology, uses Google’s Kubernetes, existing hardware and containers to deploy services across a mesh network instead of standing up dedicated servers in a data center.… Read More »

When Wim Coekaerts, Microsoft’s vice president for open source, took the stage at LinuxCon 2016 in Toronto last summer, he came not as an adversary, but as a longtime Linux enthusiast promising to bring the power of Linux to Microsoft and vice versa. With the recent launch of SQL Server for Linux, Coekaerts is clearly… Read More »
This three-part series teaches anyone interested in learning about Linux how to build what is essentially a tiny, self-contained Internet. Using old equipment and free software, you’ll build a private network (with your own domain name), build Web sites, set up an e-mail server, install and use a database, and set up a Linux distro… Read More »
