Using ODrive for Cloud Storage on Linux

Scott Lowe

A few months ago, I stumbled across a service called ODrive (“Oh” Drive) that allows you to combine multiple cloud storage services together. Since that time, I’ve been experimenting with ODrive, testing it to see how well it works, if at all, with my Fedora Linux environment. ODrive, if you’re reading this: put some effort into your Linux support and your docs, and you’ll probably get more paying customers.)

Introducing Linux Network Namespaces

Scott Lowe

In this post, I’m going to introduce you to the concept of Linux network namespaces. Generally speaking, an installation of Linux shares a single set of network interfaces and routing table entries. Please note that support for network namespaces varies between Linux distributions; Ubuntu supports them but Red Hat doesn’t. (I’m If you’re thinking about using network namespaces, be sure your Linux distribution includes support.

The Linux Migration: December 2018 Progress Report

Scott Lowe

In December 2016, I kicked off a migration from macOS to Linux as my primary laptop OS. In this post, I’d like to recap where things stand as of December 2018, after 8 months of full-time use of Linux as my primary laptop OS. Readers may recall that I was using a Dell Latitude E7370 (see my E7370 hardware review ) up until August 2017, when I put the Linux migration on hold indefinitely due to productivity concerns.

Skype for Business (S4B)—formerly Lync—is especially challenging, given that there is no native Linux client for S4B. The client is called Sky or Sky Linux.)
