Trying Out Linux
Is there any way to try out Linux without any risk and without making a commitment? The answer is yes, and in fact there are several options for the translator who is curious but hesitant to switch before learning more.
Before trying out Linux, you might want to "break the ice" by trying out some applications produced by the open source community that can run on your proprietary operating system. First, there is a web browser called Firefox and a mail client called Thunderbird. These are both available free from the Mozilla website. There is also an office suite called OpenOffice.org that is similar to the proprietary one you are already using. Once you satisfy yourself that open source software is not only as good as proprietary software, but in many cases it is much better than it, you will have more confidence and will probably have a more open mind to trying Linux. (If you subscribe to the Open Source Update newsletter for translators you will already have read about these.)
There are at least four possible ways of trying out Linux without abandoning your proprietary operating system. The first and simplest is to get a Linux distribution on a "live" (bootable) CD-ROM. This will allow you to boot your computer to run Linux without making any changes to your hard disk. Once you are done experimenting with Linux, simply eject the CD-ROM, shut down and/or reboot the computer, and voilà: Your computer is back the way it was.
In order to do this, your computer's BIOS has to support booting from the CD-ROM drive (this is true for most newer computers). Please note that this is different from the feature called "Autorun" or "Autoplay": This feature tells the operating system to run a program on a CD-ROM that is inserted after the computer is already running. By contrast, booting from the CD-ROM means having the computer look for a "boot record" on the CD-ROM when the computer starts up. Not only must your computer have this capability, but it must also be configured to try to boot from the CD-ROM drive before the hard disk. Your computer may already configured this way, so the best thing to do is save your work and close all your programs, put the bootable Linux CD-ROM in the CD-ROM drive, and restart the computer. You will see a lot of messages on the screen, but you shouldn't have to do anything. If your computer stops responding or complains about something like video resolution, try rebooting the computer or turning it off and restarting it. Don't worry about anything: It won't touch your hard disk. Once your computer boots into Linux, you will see a desktop environment that is very similar to the one your proprietary system uses. When you're done experimenting, you can easily shut down Linux (usually by clicking on a button at the bottom left of the screen, as in many propriety operating systems), but even if you can't figure out how to do this, you can simply reboot or turn the computer off. Make sure to eject the CD-ROM at some point, or your computer will boot into Linux again the next time you start it. (If you can't get the CD-ROM to eject in Linux for some reason, you can do so at an early point when the computer is rebooting.) Just one word of caution: Make sure that the CD-ROM you have is a "live" version of Linux, not a regular installation version. If the computer starts asking you questions about partitioning or formatting, you may have gotten ahold of the wrong CD-ROM. In this case, exit from the program and eject the CD-ROM.
If your computer does not boot into Linux when you reboot with a "live" CD-ROM in the CD-ROM drive, you will have to configure your computer to try to boot from the CD-ROM drive before the hard disk. This setting does not have anything to do with Linux, does not affect the normal operation of your computer, and does not have to be changed back after you have tried Linux. Older computers may not have this capability.
A few distributions which have "live" CD-ROMs that are suitable for this are the following (there are many others):
Knoppix Gnoppix Damn Small Linux PCLinuxOS SLAX Linux
All of these can be ordered from the Linux CD website: Click on the "Live CDs" category on the left side of the page. Another website where these CD-ROMs can be purchased cheaply is BudgetLinuxCDs. The live CD-ROM I recommend is Knoppix. It costs US$1.99 (plus shipping) for the CD-ROM, or, if you have a high-speed Internet connection and a CD writer, you can download the ISO image and create the CD-ROM yourself.
Note: There are many distributions of Linux that can run very nicely with less powerful hardware than current proprietary operating systems require. However, the "live" versions of Linux typically require a respectable amount of memory: Because they cannot write to the hard disk, they have to keep more in memory. If you try to run a "live" CD-ROM on a very old computer, it is possible that you will have difficulties, even though it might be possible to perform a regular installation of Linux on that same computer.
Another way to experiment with Linux is to install it on your old computer. I know you have one under your desk or in your closet. You haven't turned it on in several years, but you can't bring yourself to give it to charity. You thought that your children could use it, but then you found that the games they wanted to play on it required a more powerful computer than the one you use to earn a living. If you are certain that you don't need any information on the old computer's hard disk, you can simply install Linux on this computer. Of course this will wipe out the hard disk, so think carefully and/or make backup copies before doing this. If you choose to do this, you will need to select a version of Linux that you can install. Three very popular ones right now are Mandrake, Fedora (the successor to Red Hat), and SuSE (which has been purchased by Novell but whose distribution is still very popular in its own right). These are also available from the website mentioned above. I recommend going to the DistroWatch.com website and reading about various distributions. Details about performing a regular Linux installation go beyond the scope of this article. If you are reluctant to attempt this on your own and have a little bigger budget, you might consider purchasing a commercial package which provides manuals and some installation support: The DistroWatch.com website has links to the home pages for the various distributions, where you can buy a package including support. (A regular Linux installation may be covered in a preconference seminar at the ATA's 46th Annual Conference in Seattle.)
Several other solutions are mentioned below, but they are not discussed in detail here since they either involve additional costs or are more difficult to carry out. However, although these solutions are not good ways to try out Linux, they do represent ways to run Linux in parallel with a proprietary operating system, for people who feel they need both operating systems. (The following solutions may also be covered in another article at some point in the future or possibly at a preconference seminar at the ATA's 46th Annual Conference in Seattle.)
If you do not have an old computer, or if you use your extra computer as a backup and are reluctant to wipe out its hard disk, another possibility is to get an additional hard disk and install Linux on the second hard disk. If this is done properly, there is no danger of touching the data on the other hard disk. It will then possible to use either operating system. If you expect to use one of the operating systems only rarely, you can switch operating systems by turning off and unplugging the computer, unplugging one hard disk, and then plugging in the other one; if you expect to switch back and forth frequently, it is better to leave both hard disks plugged in and use a special program called a "boot manager" to select which one to boot from at startup. This approach can be used either with a backup computer or with your main computer. Since this involves the purchase of an additional hard disk (US$50.00-100.00 at today's prices), this approach is not the best way to try out Linux, and it will not be discussed here. (Please remember that even though this is not a good way to try out Linux, it is a very good solution for a person who wants to run both Linux and a proprietary operating system.)
It is also possible to have both Linux and a proprietary operating system installed in separate partitions on the same hard disk. In this case, as when the operating systems are installed on separate hard disks, a boot manager is used to select which operating system to boot when the computer is turned on or rebooted. If your hard disk is big enough this is a perfectly good solution, and does not involve any additional cost, but configuring it is tricky. There are utilities such as System Commander that can help guide a user through this, however this is still recommended only for people who are very experienced with computers, and it will not be covered here.
There is a software package available called VMware Workstation which allows another operating system to be installed like an application. For example, it is possible to run a proprietary operating system, install VMware Workstation, and then install Linux as you would an application. Linux is kept separate from your other operating system and cannot disrupt anything. (Even better, VMware Workstation can be installed on a Linux system, and then a less-stable proprietary operating system can be installed as an application from within Linux.) This solution involves purchasing VMware Workstation (US$189.00 as a download at the time this was written) and also requires a fairly powerful computer, so it is best suited to people who have to run both operating systems at the same time: This is not the way to experiment with Linux, so it will not be covered here.
Now,I would wish you good luck, but you won't need it.
