Open Source Experts Since 1999

If you’re a student like I am, you know how important it is to save money. Some students are too busy with their studies to work at all, and those who can are usually only able to do so part-time. And, like books and tuition, software is a significant source of financial burden to the average student. While it’s true that student licensed versions of software are significantly discounted, popular titles such as Microsoft Office will still cost you somewhere in the ballpark of $130. And of course, that’s only if you don’t intend to use the software for anything other than your academic or personal endeavours. If you utilize the same applications on the job, you’ll find that you’re no longer eligible for student licenses, and suddenly you’ll discover that $130 magically turns into $300.

Fortunately, the current digital climate is rife with free software alternatives, which have the potential to save students (or parents!) hundreds of dollars.

The Operating System

Let’s start with the most fundamental bundle of software, the operating system (hereby abbreviated as OS.) The OS is what sits between the hardware and the user’s applications. Some examples are Microsoft Windows and Mac OS X.

For many students, purchasing an OS will be a non-issue, as most computers come with one pre-installed. For those in this category, most of the software mentioned below will run on both Windows and Mac. That being said, there are also a significant number of people who need to include an OS in their financial plans. Perhaps you purchased your computer used and without software. Or, maybe the OS on your machine is old and needs to be upgraded. You could have even assembled your own computer, as many hobbyists do.

It’s true that students can purchase Microsoft Windows at a discount of 30-60% off, but why would you do that when you can get your OS for free? Over the last few years, a veritable cornicopia of easy-to-use free software-based OSes have emerged, the most popular, and in my opinion, the easiest to install and use, being Ubuntu ( For the more technically inclined and perpetually curious, there are a slew of other Linux distributions, as well as the *BSD family of OSes — FreeBSD (, NetBSD (, OpenBSD (, PC BSD ( and Dragonfly BSD ( — and Sun’s OpenSolaris (

In reality, we do still live in a Windows world, so you may find yourself in a position where you have to use a program that only runs on Windows. Luckily, there’s a very mature and very complete open source implementation of the Windows API that’s been actively developed since 1993 called WINE ( You simply install WINE through the point-and-click interface provided by your OS and install your Windows applications on top of it. Many will run out of the box, and others will run with a minimal amount of tweaking.

Office Productivity

As mentioned earlier, a student copy of Microsoft Office will cost roughly $130, and in some cases, students won’t even qualify for the student license, making the product much more expensive. So then, simply by installing a single free software replacement, you’ve literally saved hundreds. There’s a fantastic open source alternative called OpenOffice (, a spin-off from Sun Microsystems, Inc. The download is a little large (over 100MB), but the price tag is worth it (it’s free), and OpenOffice really is a solid application capable of doing anything Office can. It includes components that replace Word, Excel, Powerpoint and Access, as well as additional components for drawing and for editing HTML documents.

In addition, you’ll find Scribus ( for desktop publishing and the creation of professional quality PDFs and Dia ( for drawing diagrams, roughly like Microsoft Visio.


Of course, no college-ready system is complete without the ability to play movies and music! Fortunately, open source has you covered there as well. With Totem ( and Xine (, playing your videos on Linux is a snap (Windows and Mac users of course have their own respective built-in players and don’t have to worry about this.) As well, there are applications like Banshee ( that do a great job of managing your music (it also plays videos.)

You’ll also more than likely be managing a great deal of pictures. For editing them, you’ll find the GIMP (, which is very similiar to Adobe’s Photoshop, and for browsing and managing your pictures there’s F-Spot (

You’ll only run into a couple of hitches when dealing with multimedia on an open source OS. The first is that you won’t be able to play many Windows Media files. Fortunately, this can remedied by purchasing the Fluendo Windows Media Playback Bundle ( True, it’s not free, but for $20 it’s a small price to pay compared to all the hundreds of dollars you’ll be saving on everything else, and if you can live without Windows Media, you can save yourself the expense. The second is that technically, according to the controversial Digital Millenium Copyright Act (, you’re in a legal predicament if you install software to decrypt your DVDs. More than likely nobody’s going to care, and the software to do so is readily available and in common widespread use, but if you choose to play your DVDs on an open source OS you should first take the time to thoroughly understand where you stand from a legal perspective. [Ed. note: there are fully licensed DVD players available for Linux, but even so, legal scholars now feel that this area of the DMCA has not yet been fully tested in court, but recent precendents suggest that if it were, in the end, that Fair Use doctrine would win out in the end over the DMCA – Ed.]

A Plethora of Other Goodies

Depending on your field of study, you’ll find many other professional-quality free and open source applications that are outside the scope of this blog that will save you even more money. Just google around. You’ll find all sorts of amazing applications, all of them free.


Fellow students, let loose the shackles of expensive proprietary software and embrace the freedom of open source. Not only will you save hundreds of dollars, you’ll be drawn into a community of users and developers that are passionate about writing and supporting software. Once you get used to using free software alternatives like these one from, you’ll wonder how you ever got by without it.

Aside from all the usual green advice, what can a conscientious SysAdmin do to save money during this time of rising energy prices and a challenging economic situation?

Here is eRacks’ top-ten list of recession-proofing strategies:

    • 1 – Update the Linux OSes if they are older than kernel 2.6.21, to take advantage of the ACPI tickless idle. Install PowerTOP (on Intel-based desktops & notebooks) or other similar tools that examine power consumption by application.
    • 2 – Basic maintenance: vacuum the vents (from the outside of the chassis, with the computer off). The buildup of dust and dirt prevents airflow. After cleaning, the systems will cool more easily. The vacuum and/or the little bottle of compressed air are your friends. A word of caution though: don’t even think about reversing the vacuum to blow the dust inside the computer case. The household dust inside the vacuum is not a good thing for the computer (or you). In fact, don’t stick the vacuum inside the computer case at all, since vacuums create static electricity which can also damage your system.
    • 3 – Re-think your network diagram. Old systems are often wasteful of energy.
      • Consider consolidating systems; Own your own virtualization system:
        eRacks/SOLO and eRacks/SUITE are capable of running several virtual machines simultaneously.

        eRacks/SOLO Virtualization Server

        Your physical host server can be configured with your choice of a virtualization host, including the freely available version of VMWare or Linux-native KVM (Kernel-based Virtual Machine), as well as a large number of possible virtual operating systems and applications, including web, DNS, email, proxy and other infrastructure services.You’ll save power, save money, and also allow for more centralized administration and ease of backup. eRacks will even pre-install the targeted configurations of your choice. Just ask.
      • Or take advantage of a hosting solution like Libre Hosting. Get full (root) use of your own virtual server fast. This is a great way to test out a new project, minimizing both your financial investment and configuration effort.
      • Or use newer low power servers like the eRacks/LITE, eRacks/QUIET, and any of our desktop line. eRacks will happily customize a system for low power usage, with your requirements.
    • 4 – Plan for upgrades. Buy systems that use only industry-standard components (like eRacks!) so that you can upgrade without being tied to a manufacturer and higher prices.
    • 5. Plan for efficient scaling. This depends on the most likely way(s) your company/institution would require expansion in the future. An increase in number of users, production, machine power, etc would each create different infrastructure requirements. Planning longer term, could enable growth while minimizing costs. Using hosted virtualized servers could allow for more flexibility in scaling, up and down, – very handy in peak demand time.
    • 6. Rethink security and firewalls. Use preventive measures now, rather than costly fixes later. Read summaries of firewall logs to gauge how busy your firewall system is. Consider options like eRacks’ failover redundant firewall:

eRacks/TWINGUARD Redundant Firewall

  • 7. Update your sysadmin tools. Make a bootable DVD or USB drive with your favorite sysadmin utilities on it. Save time by setting up system monitoring and detect any issues before they become big problems.
  • 8. This one is for the marketing/sales dept: Find clients that are recession-proof. Where are your main profits coming from? Do you have a few clients in markets that are recession-proof? If not how can you attract those clients, now and get on their vendor lists? – Educational institutions like Trilogy Education Services are usually somewhat stable in their purchasing because people tend to return to school in times of a recession.
  • 9. Again to the marketing guys: Globalize your products and presentation with the help of SEO services. Keep in mind that a weak dollar may increase your international customers.
  • 10. Always wise: Keep notes – keep an internal company wiki. From our experience, this can be a great tool and reference, saving time, effort and money!

Remember, recession isn’t permanent, but can be long. And playing it smart now will help, and quite possibly make all the difference.
