Hassle-free computing with Linux

User friendly, stable and secure

This may be of interest to you if you're tired of the hassles and expenses associated with using Microsoft Windows – viruses, security threats, the version treadmill and the everyday problems one takes for granted with that blighted operating system. If you think it might be time for a change, read on.

The change you’re looking for could be another operating system. You'd be familiar with Mac OSX, which is a good alternative, but it's not the only one. The Mac has a free cousin, known as Linux, which also offers a way to escape the hassles of Windows. marbles the cat - and that's that!Mac OSX and Linux are related because they’re both based on Unix, a long-established, industrial-grade system commonly used on mainframes and supercomputers (the ‘X’ in both names comes from 'Unix'). Both have inherited Unix’s inherent reliability, stability and security.

You might not have heard of Linux before, but that doesn’t mean it hasn’t been around. It was first released in 1991 (Mac OS X was released in 2002), but was for some years too 'geeky' for the average computer user. However, Linux has come a long way, and these days it's probably more user-friendly than Windows – it's certainly less troublesome. The writer, who is no geek, has been using Linux since mid-2006.

Many others use it too, and not just on desktop PCs. For example, Android is a version of Linux, modified for use with touch screen devices. That alone makes it the most popular operating system in the world. The Google Chrome OS (used in ‘Chromebooks’) is a version of Linux as well. tux the linux mascotBehind the scenes, most web servers run Linux, and it is also embedded in the electronics of machines everywhere, from Blu Rays to BMWs to Boeings. PCs aside, wherever there’s a need for an operating system, you’re much more likely to find Linux than Windows.

And there are good reasons for this, reasons that also apply to your PC at home. Perhaps the most important is security, as Linux is not touched by the malware that afflicts Windows. This allows you to confidently do things that can be worrying with Windows. For example, you can use Firefox or Google Chrome (not Internet Explorer) to do your internet banking or online shopping in relative safety. You still have to be careful, but it’s much, much safer, and I think that's worth more than all the Windows anti-virus software in the world.

There are many other benefits too. One always has the latest version, and can freely download a program for almost any purpose. And the system is straightforward to use. You will have more control over your computer, and you’ll no longer be subjected to Windows’ quirks and annoyances.

What's the catch?

Sounds too good to be true? Well, there’s always a catch, and in this case it’s the fact that most Windows programs won’t work with Linux. In practice this is not a major problem; most users simply install Linux alongside Windows (it's an installation option) and choose one or the other when booting up. Choose Windows when you need to use your Windows programs, just as you always have. Or choose the Linux 'side' instead. The choice is yours and there is nothing to lose. This is called ‘dual booting’.

Some of the programs made for Linux will be familiar, such as Firefox and Chrome, but most Linux programs will seem like ‘generic’ equivalents of those you currently use with Windows. This doesn’t mean they’re less capable but, being different, there has to be a learning curve.

If you're too busy to get used to these programs, or not very confident with computers, consider using Linux for your online applications (e.g. banking/purchasing, email, Google Docs, web surfing, social media), which involves no learning curve, and Windows for the rest. This way you get most of the benefit for next to no effort.

You can see that the need for Windows will diminish as more and more online, browser-based apps replace the desktop variety.

Choose the right version of Linux

Linux is available in many flavours, or distributions (‘distros’). This is because, strictly speaking, Linux is just the nucleus of an operating system. The nucleus, or ‘kernel’ in Linux-speak, is supported by many other pieces of software to make up a complete system. Each distro is actually the Linux kernel with a unique mix of supporting software, and each is designed with a different type of user in mind.

You can choose the distro that suits you by using one of several online 'distro selectors'. A little homework will save some trouble, but you can afford to experiment because most distros are available free of charge. The most popular distros are Ubuntu, Fedora and Mint, foss street signbut only you can decide which is best suited to your needs. My choice is 'Ubuntu'.

Most distros are free because Linux is 'Free and Open Source Software' (FOSS), which is produced and constantly updated by volunteer programmers. FOSS can be used and changed by anyone. Being open to anyone, FOSS software is constantly under close scrutiny, and this is why you can be sure there are no nasties in it. Most of the programs that work on Linux are FOSS.

Potential pitfalls

Using Linux is generally a straightforward thing, but one potential source of angst is printing. This need not be an issue, as nearly any HP printer will work out of the box. However, if you have your heart set on another brand you will need to go to the 'Linux printing' website to check that it works with Linux. Alternatively, you can go to a site dedicated to selling printers (and other things) that are known to work on Linux, such as Think Penguin.

Obtaining and installing Linux

Some distros will send you a disc ready to use, but the most common way is to download something known as an ‘iso’ file and burn it to a disc. Insert the disc and follow the prompts. Some distros now allow you to install from a USB drive instead, but either way it's fairly straightforward and much quicker than installing Windows, with no 'authentications' or strings attached. The website for your distro will give you detailed instructions, but to get an idea, here's some instructions for installing Ubuntu.

Installation options

Most distros offer three installation options:

I would suggest another option: Many of us have an old laptop lying around the house; you know, the one that cost so much (ten years ago!) you can't bear to throw it out. If this applies to you, try installing Linux on it. This could be a good 'practice run' to see what's involved before you do anything to your everyday computer. What's more, you may be pleasantly surprised with how well it runs (much better than it ever did), as Linux has much lower system requirements than Windows.
