Tech Tips

Open Formats, Open Editors

E-books are currently quite a hot topic in the publishing world. Heck, for the past few months, it's been quite a hot topic here as well! Thankfully, digital publication doesn't have to mean proprietary formats and DRM-laden files. more>>

Kill A Watt: Now with Less Math!

If you're interested in how much energy your electronics use, it's hard to find a device better than a Kill A Watt—except maybe the Kill A Watt EZ! P3 International now offers model P4600, which provides the same features as its predecessor, but it also automatically calculates device cost per day, week, month or year. more>>

Nuvola: the Linux Choice for Cloud-y Music

Nuvola Player (formerly known as google-music-frame) is a Linux application that integrates cloud-based music services into your Linux desktop. I've tested it only with Google Music, but Nuvola now supports Google Music, Grooveshark, Hype Machine and 8tracks. It also supports Last.FM scrobbling. more>>

Spice Up Your Desktop with Cinnamon!

If you are disgruntled by the new interfaces provided by recent distribution releases, namely GNOME 3 and Unity, you might want to take a look at Cinnamon. With its traditional feel and extreme theme-ability, Cinnamon is a desktop interface bound to spice up anyone's computer. more>>

Calibre in the Cloud

I've mentioned before that I keep my entire e-book collection in my Dropbox folder, and I can access it anywhere I have a Web connection. I didn't come up with the idea myself; instead, I shamelessly stole the idea from Bill Childers. I suspect he stole it from someone else, so feel free to steal the idea from me. more>>

Make TV Awesome with Bluecop

A few weeks back, I was whining that although Doctor Who was available on Amazon Prime streaming, I didn't have any way to watch it on my television. Thankfully, my friend Richard Servello pointed me to the bluecop repo for XBMC. Not only does bluecop support Amazon Prime streaming, but it also has add-ons for Hulu and countless other network-video-streaming collections. more>>

Cryptocurrency: Your Total Cost Is 01001010010

Most people have heard of gold. Most people are familiar with dollars. For a handful of geeky folks, however, the currency they hope will become a global standard is digital. Whether it's a problem or not, the currency you use on a day-to-day basis is tied to the government. more>>

Mercurial - Revision Control Approximated

A short while ago, an article appeared in Linux Journal implying Git was the be-all and end-all of source code revision control systems ("Git—Revision Control Perfected" by Henry Van Styn, August 2011). more>>

Science the GNU Way, Part I

In my past several articles, I've looked at various packages to do all kinds of science. Sometimes, however, there just isn't a tool to solve a particular problem. That's the great thing about science. There is always something new to discover and study. But, this means it's up to you to develop the software tools you need to do your analysis. more>>

Non-Linux FOSS: TrueCrypt

TrueCrypt is a fully open-source tool for encrypting data. That data can be on a completely encrypted hard drive, or just an encrypted image file. Thankfully, the encryption works the same regardless of your platform, so Windows and OS X users can share encrypted files between computers. more>>

EPUBReader

With our recent transition to a digital-only format, it's now possible to consume Linux Journal in a number of ways. For those so inclined, it's even possible to print each issue and bind it into a paper magazine. (The PDF lends itself quite nicely to that in fact) Electronically speaking, however, it's hard to beat the .epub/.mobi editions. more>>

Rock Your Webcam Like It's 1995

Many Webcam applications exist for Linux. If you want to play with self-portraits, there's Cheese. If you want to set up a security system in your office, there's Motion. But, if you just want to have some fun, give HasciiCam a try. more>>

You Need A Budget

This time of year is often rough on finances, and although there are many money-management tools available for Linux, none are quite like You Need A Budget, or YNAB for short. Unlike traditional budgeting programs, YNAB focuses on a few simple rules to help you get out of debt and, more important, to see where your money is going. more>>

Casper, the Friendly (and Persistent) Ghost

Creating a live Linux USB stick isn't anything new. And, in fact, the ability to have persistence with a live CD/USB stick isn't terribly new. What many people might not be aware of, however, is just how easy it is to make a bootable USB stick that you can use like a regular Linux install. more>>

gStrings in Your Pocket

What may sound like a perverse concept is actually one of the many ways smartphones can change your life. If you play a musical instrument but don't happen to have perfect pitch (most of us, sadly), you can buy a tuner, pitch pipe, tuning fork or any number of other aids to keep yourself in tune. If you have a smartphone in your pocket, however, you also can simply download gStrings. more>>

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale?
