Digital and Analog Circuit Simulation with Ksimus
May 18th, 2009 by Mike Diehl in
I took a Computer Logic Design class in college, so when I stumbled upon the Ksimus Circuit Simulator, I was intrigued. At the risk of waxing nostalgic, I remember what it was like to build circuits in school. We'd spend hours the night before the lab designing our circuit, being careful to list each interconnection. We had to keep track of which pin numbers on each chip were to be connected.
Would You Like Linux With Your Jello?
July 3rd, 2009 by Justin Ryan
It goes without saying that nobody wants to be in the hospital. Bland food, no privacy, and gowns that leave nothing to the imagination — not to mention the procedures being performed — don't exactly make ones visit a relaxing trip to the spa. We all know, however, that Linux can make anything better, and now, whether you're recovering from a lung transplant or liposuction, Linux is there to make your life in the infirmary just a little bit sunnier.

Reserve Your Space on the Australian Stage
July 1st, 2009 by Justin Ryan
The Triple Crown of Linux conferences — if there is one — is surely the Linux Symposium, the Linux Kongress, and linux.conf.au. It was just a month ago that we passed on the message to LinuxJournal.com readers that the time to get their name on the Kongress program was nigh, and now it is time to do the same for the southernmost jewel in the crown.

Happy Canada Day to all my Canadian friends, both at home and abroad. June was a very busy month for me, which is why there were so few postings and I wanted to jump on July with a really big bang, but I am having trouble finding a topic worth discussing.
Help Me Go Mano a Mano with Microsoft
July 1st, 2009 by Glyn Moody
Next week, I'm taking part in a debate with a Microsoft representative about the passage of the OOXML file format through the ISO process last year. Since said Microsoftie can draw on the not inconsiderable resources of his organisation to provide him with a little back-up, I thought I'd try to even the odds by putting out a call for help to the unmatched resource that is the Linux Journal community. Here's the background to the meeting, and the kind of info I hope people might be able to provide.

Could There Be an AndroidFox?

Google's Linux-based mobile operating system — Android — has become a popular choice for phonemakers worldwide. Now, if Firefox developers are getting what they think they are, we may finally see the combination of Google's power OS with Mozilla's groundbreaking browser
Pianoteq3 For Linux: A Product Review
June 29th, 2009 by Dave Phillips in
On the 15th of May 2009 the Modartt company announced the release of version 3.0.3 of their award-winning Pianoteq, a professional-quality digital keyboard instrument created by an audio synthesis method known as physical modeling. The program is vastly praised by its users, but in order to feel the love you've had to run a Windows machine or a Mac box. Until now, that is. The latest release introduces various new attractions, and the one that interests me the most is support for a native Linux version. Check it out, commercial music software's finest virtual keyboard instrument is now available for Linux.

Do You Do the Drupal?
June 27th, 2009 by Justin Ryan
The Drupal content management system is one of the most popular engines for dynamic websites — indeed, it powers the site you're visiting right now. All this powering doesn't happen by itself, though, and the developer community that does the dirty work behind the scenes is in need of a bit of Linux labor.
Asking a Yes/No Question from a Bash Script
June 26th, 2009 by Mitch Frazier in
In order to avoid this common mistake I often have my shell scripts prompt me for a yes or no answer before they proceed. The function described here is for doing that: asking a question and validating the answer.
Ksplice Boots the Reboot
June 26th, 2009 by Justin Ryan
It's doubtful that very many users enjoy reboots. Although system uptime is often worn like a badge of honor — as though power-cycling were some form of humiliating defeat — the majority of us can probably agree that having to restart is a pain, if only for the lost time involved. It almost seems as though the annoyance grows exponentially the more frequent they come.
Tech Tip: Determining What's Been Changed on RPM Based Systems
June 25th, 2009 by Vijay Avarachen in
As a consultant, I am often faced with an unfamiliar Linux system (usually RHEL). I always find it useful to understand which files that shipped with rpm packages have been modified, since it's usually a good indicator of what customizations have been performed on the system. To determine the modified files, I simply run:

News Flash: Linux Kernel 3.0 to include an on-the-go Expresso machine interface! Ok, maybe not, but Linux is definitely going mobile, from phones to e-readers. Find out more inside about Android, the Kindle 2, the Western Digital MyBook II, The Bug, and Indamixx (a portable recording studio). And if you've gone mobile and you been wanting more Emacs in your life then check out Conkeror.
To compliment the mobile we've got the stationary: parsing command line options with getopt, checking your Ruby code with metric_fu, and building a secure Squid proxy. How is this stationary you ask? What can we say? It's not. We just wanted to see if anybody actually read this part of the page :) .
All this and more, and all you have to do is get your hot sweaty hands on the latest copy of Linux Journal.
