How many times you have been hit by unit tests failing because of environment differences between you and other team members? How easy is it to build your project and have it ready for development?...

Android Candy: Google Keep

I love Evernote. I pay for a premium membership, and to be honest, I don't think I even use the premium features. I just love Evernote so much, I want to support the company. But in the spirit of fair comparison, I forced myself to try Google Keep. more>>

Handling the workloads of the Future

The history of computing can be traced by the popular buzzwords of the day. In fact, at some point we should run a contest where everyone submits their 5 all-time favorite computer industry buzzwords. There have been dumb terminals, smart terminals, client server, thin client, peer-to-peer, virtualization, containers, cloud, paas, saas, iaas…the list, and the acronyms stretch to the horizon. more>>

Raspi-Sump

In June 2013, we had the unfortunate luck of a basement flood, caused by a tripped electrical breaker connected to our sump pump. There are so many things that can go wrong with a sump pump. You always are on guard for power outages, blown breakers, sump pump failures, clogged pipes and all manner of issues that can arise, which ultimately can end with a flooded basement. more>>

diff -u: What's New in Kernel Development

Containers are very tricky to implement. Trying to isolate sets of resources from each other completely, so that they resemble a discrete system, and doing it in a secure way, has to be addressed on a feature-by-feature basis, with many caveats and uncertainties. more>>

Non-Linux FOSS: Don't Type All Those Words!

We've mentioned Autokey as a great tool for text replacement in real time on Linux. Thankfully, there's an option for Windows users that actually is even more powerful than Autokey! AutoHotkey is a similarly named application that runs strictly under Windows. more>>

Computing without a Computer

I've covered a lot of various pieces of software that are designed to help you do scientific calculations of one type or another, but I have neglected a whole class of computational tools that is rarely used anymore. Before there was the electronic computer, computations had to be made by hand, so they were error-prone. more>>

Autokey: Shorthand for Typists

For years I avoided installing keyboard shortcut tools on my computers. I thought dog-gonnit, if something needed to be typed out, I'd type every letter myself. Recently I capitulated, however, and I must say, going back seems unlikely. If you've never tried a text-replacement app, I highly recommend doing so. more>>

How Can We Get Business to Care about Freedom, Openness and Interoperability?

They use our stuff. Why not our values too?

At this point in history, arguments for using Linux, FOSS (free and open-source software) and the Internet make themselves. Yet the virtues behind those things—freedom, openness, compatibility, interoperability, substitutability—still tend to be ignored by commercial builders of new stuff. more>>

December 2014 Issue of Linux Journal: Readers' Choice

The Best of the Best

I love the Readers' Choice issue. I jokingly say it's because all the work is done by the community, but honestly, it's because I love hearing the feedback from everyone. Year after year, I inevitably learn about a new technology or application, and I'm usually surprised by at least one of the voting results. more>>

Non-Linux FOSS: XAMP

One of my career iterations put me in charge of a Windows server that had Apache and PHP installed on it to serve as a Web server for the corporate intranet. Although I was happy to see Apache used as the Web server dæmon, the installation on the Windows server was the most confusing and horrifying mess I've ever seen. more>>

The Awesome Program You Never Should Use

I've been hesitating for a couple months about whether to mention sshpass. Conceptually, it's a horrible, horrible program. It basically allows you to enter an SSH user name and password on the command line, so you can create a connection without any interaction. A far better way to accomplish that is with public/private keypairs. more>>

Days Between Dates?

Alert readers will know that I'm working on a major revision to my popular Wicked Cool Shell Scripts book to come out later this year. Although most of the scripts in this now ten-year-old book still are current and valuable, a few definitely are obsolete or have been supplanted by new technology or utilities. No worries—that's why I'm doing the update. more>>

Synchronize Your Life with ownCloud

Like most families these days, our family is extremely busy. We have four boys who have activities and appointments. My wife and I both have our own businesses as well as outside activities. For years, we've been using eGroupware to help coordinate our schedules and manage contacts. The eGroupware system has served us well for a long time. However, it is starting to show its age. more>>

A GUI for Your CLI?

For new Linux users, the command line is arguably the most intimidating thing. For crusty veterans like me, green text on a black background is as cozy as fuzzy slippers by a fireplace, but I still see CLI Companion as a pretty cool application. more>>

One Click, Universal Protection: Implementing Centralized Security Policies on Linux Systems

As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
