Bash Sub Shells
35 minutes ago
When writing bash scripts you sometimes need to run commands in the background. This is easily accomplished by appending the command line to be run in the background with an ampersand "&". But what do you do if you need to run multiple commands in the background? You could put them all into a separate script file and then execute that script followed by an ampersand, or you can keep the commands in your main script and run them as a sub-shell. -
Linux: Should You Use Twice the Amount of Ram as Swap Space?
1 hour, 5 minutes ago
Linux and other Unix-like operating systems use the term "swap" to describe both the act of moving memory pages between RAM and disk, and the region of a disk the pages are stored on. It is common to use a whole partition of a hard disk for swapping. However, with the 2.6 Linux kernel, swap files are just as fast as swap partitions. Now, many admins (both Windows and Linux/UNIX) follow an old rule of thumb that your swap partition should be twice the size of your main system RAM. Let us say I've 32GB RAM, should I set swap space to 64 GB? Is 64 GB of swap space really required? How big should your Linux / UNIX swap space be? -
Linux distros and Apple beat Microsoft’s homepage uptime

Bash One-Liner Script To Produce Somewhat-Fancy Output Of Who's On Your Linux Or Unix Box
7 hours, 35 minutes ago
Today we're going to shoot out a quick one liner script that can come in handy from time to time. It doesn't fall under the "necessary" category (or, maybe not even the "useful" one ;), but it's nice to have for those times when you just don't feel like doing any extra typing or expending the effort required to separate the wheat from the chaff on a screen full of garbage output. That is, as I've always understood, one of the main reasons to script things out in the first place. The other reasons, like automation, efficiency, etc, are pretty much ignored here, even though we will be automating a repetitive action and that, by definition, will make our waste of company time more efficient. No matter how you look at them, automation and efficiency always seem to be a good thing ;) -
Good (Linux) Things on the Horizon
9 hours, 35 minutes ago
We seem to be in a particularly good period for Linux at the moment. We've recently gotten the Mandriva 2009.0 and Ubuntu 8.10 Intrepid Ibex releases, and both of them seem to be very good. There will be a number of new releases coming in the next few weeks, as well: -

Bash Cable, Dish and Local TV Listings Script For Linux Or Unix
13 hours, 35 minutes ago
I'm beginning to think that this script should be put on my SourceForge page and maintained there. It's not that I mind doing these weekly updates, but I feel like I'm writing the same thing over and over again, where I could be offering you, the reader, more value by producing different scripts in its place. If you have a few seconds, please answer the short poll on the right hand side of the blog. If public opinion wants this project worked out on the blog, then so be it. If you're all getting sick of these updates, I can move this to my SourceForge page, as a project, and produce more original content for our Monday script posts. -
The Individualism of Open Source

When most people hear about open source software, they think of charity, altruism, and "free stuff." At a deeper level, however, the open source movement is often highly individualistic. -

A graphical way to MySQL mastery
MySQL GUI Tools is a suite of graphical desktop applications for working with and administering MySQL servers. The suite consists of three tools: MySQL Query Browser, MySQL Administrator, and MySQL Migration Assistant (available only on Windows). We'll look at the first two to see how well they let us manage MySQL without using the command line.
Using external commands in Nagios
System monitoring tool Nagios offers a powerful mechanism for receiving events and commands from external applications. External commands are usually sent from event handlers or from the Nagios Web interface. You will find external commands most useful when writing event handlers for your system, or when writing an external application that interacts with Nagios.
SoftMaker Office 2008 focuses on compatibility with Microsoft Office
The free and open source office suite OpenOffice.org might be a killer app for many, but its inability to properly display documents created in the proprietary Microsoft Office formats hinders its widespread acceptance in multi-OS business environments with many legacy .doc and .xls files. If changing over to an open document format is not an option, try SoftMaker Office. It's no OpenOffice.org-killer, but it's a full featured office suite that has great compatibility with Microsoft Office. Sure, it costs $80, but you can increase your karma by running it on Linux.
Speed up your Internet access using Squid's refresh patterns
Bandwidth limitation is still a problem for a lot of people who connect to the Internet. You can improve your available bandwidth by installing Squid caching proxy server on your network with configuration parameters that will increase your byte hit rate, giving you about 30-60% more bandwidth.
Sun wrestles itself with StarOffice 9
StarOffice 9 reminds me of the classic Monty Python skit in which Graham Chapman wrestles himself. Although StarOffice is being aggressively presented as an alternative to Microsoft Office, it seems to be equally marketed and bundled to compete against OpenOffice.org, the free software project that is sponsored by Sun and that shares a common code base with StarOffice. The trouble is, the differences between the two have diminished with each release, until, with StarOffice 9, you have to wonder who the potential customers might be.
Manage your music with ID3 tag editors
The Linux desktop comes with a variety of multimedia players, such as Xine, MPlayer, and Amarok. Yet all digital media players are only as good as the files they have to work with, and preparing those files requires the best tag editor you can find. I checked out half a dozen of the more popular and stable graphical ID3 tag editors available for Linux. I found that going from no tags to great tags requires keeping more than one of these editors on hand.
Doing a diff without touching the command line
With diff-ext, GNOME users can compare and merge files from within Nautilus. If, instead, you use KDE 3, try out kdiff-ext from the same site, which works with Konqueror. Each utility handles paths to files and directories and invokes an external diff tool to perform the grunt work. With diff-ext you can easily compare two files with different names, from different directories, or whole directory trees.
iPhone applications for the Linux user
The iPhone and iPod Touch haven taken the mobile market by storm. Apple's AppStore is full of interesting applications that take advantage of the two devices's capabilities. But what's in there for Linux users? Sadly, GTKPod and Amarok cannot yet transfer files on an iPhone with the 2.x firmware upgrade, but there are other interesting ways your iPhone can interact with your Linux desktop and even servers.
sK1 vector in on good illustrations
From its name, you'd never know that sK1 is a good vector graphics drawing program, in the same category as better-known names like Inkscape, Dia, and OpenOffice.org Draw. Moreover, sK1 includes a feature that other Linux applications lack: it can read CorelDraw's CDR files and convert them to Linux-friendly formats.
Treat your C code like scripts with C Cod
C Cod is a front end to your C, C++, or Objective-C compiler that lets you treat C more like a scripting language. C Cod comes with C Server Pages, which provides support for CGI so you can write Web applications in C or C++ and have them automatically compiled on demand.
Slumberland rests easy after move away from proprietary Unix
In 2005, when Slumberland faced end-of-lifecycle replacements of its proprietary Unix platform, its warehouse management system (WMS) vendor suggested a move to Red Hat Linux and commodity x86 servers. Seth Mitchell, the infrastructure team manager at the large furniture retailer, gladly agreed. Upper management wasn't quite as quick to jump on the open source bandwagon, but once the cost savings started rolling in, everyone agreed that it was a profitable decision.
Crafting offers and invoice documents with Kraft
Kraft helps you keep track of business offers and invoices and can generate PDF files to help you easily issue these routine documents to third parties. Since Kraft is a KDE application, it can draw contact information directly from your KDE address book, so you don't have to duplicate or sync your contacts in order to generate an invoice.

Bug Labs creates open source Lego for software engineers
Most of the new breed of open source hardware centers on specific products. Bug Labs is taking a different approach. Instead of developing particular devices, Bug Labs' goal is to provide a Lego-like collection of open source hardware and software that customers can use to build their own devices. According to CEO Peter Semmelhack, the result should be not only a higher degree of innovation, but also a forerunner of the hardware business of the future.
Set Mantis to track your bugs
Mantis is that rare bug-tracking program for small projects that is neither too bloated nor too featureless. It's an excellent choice for developers who need a bug tracker that the average computer user can use. Its clean interface and numerous features make bug tracking fast and easy.
Back-of-the-napkin calculations with Frink
Linux users have a myriad of calculators and unit conversion tools at their disposal. To set itself apart, Frink aims to track units for you and give you a way to quickly perform little conversions and real-world calculations without burdening you with needless details.
Ace Suares: A big Linux advocate on a small island (video)
The word "big" has two meanings here. Ace Suares is not only a big-time GNU/Linux and FOSS advocate, but he is close to 2.5 meters tall and built like a football lineman. He lives on the island of Curacao in the Netherland Antilles, where he and his wife run a small Web design and hosting firm that (of course) runs Linux servers. But trying to convert other IT people on Curacao to the FOSS cause has not been easy, and has caused Ace plenty of frustration over the years. Somehow, he keeps going; arranging conferences, holding LPI Certification classes, and generally talking up Linux to his clients, friends, and even to strangers whose businesses or government agencies might be made more efficient by using FOSS instead of proprietary software. Now we'll get out of the way and let Ace tell his story directly to you in the following video. (It's about 13:20 long.)
Clone your Ubuntu installation onto a new hard disk
Just upgraded your system with a shiny new hard disk and want to make it your new book disk? Cloning Ubuntu to another hard disk is easy. In fact, Ubuntu provides tools to clone the entire hard disk -- including the Windows partition, if there's one on there. This is the kind of fundamental task that Linux excels at, in fact.
Tidy up your mailboxes with Archivemail
Over time, people tend to accumulate a large number of messages in various email accounts, most of which they never bother with again. The problem is particularly acute for administrator accounts that receive routine notifications of events that are viewed, if at all, no more than once. The archivemail tool lets you easily archive these old messages and thereby free up some disk space and improve your mail client's performance.
Portrait: FOSS legal leader Andrew Updegrove
Attorney Andrew Updegrove specializes in technology, intellectual property, and standards. While other lawyers can make the same claim, few have his credentials -- maintainer of an online repository about standards consortia, former board member of the Linux Foundation, and progenitor of a major open source license.
