Advantages and disadvantages of the open source software such as Linux

Advantage #1 - Stability

If you have used other operating systems, once you have made the switch to Linux, you will notice that Linux has an edge over Windows here. I can remember rebooting Windows many times over the years, because an application crashed, and I couldn't continue working. Linux can crash also, but it is much harder to do. If an application crashes in Linux, it will usually not harm the kernel or other processes.

Advantage #2 - Free Software

Most software can be obtained without cost for Linux. For example, one thing that has kept people from Linux is the lack of office software. That has changed with Open Office, and now you can edit documents and presentations from the popular Microsoft software. The conversion isn't 100% perfect, but it has worked remarkably well in allowing me to correspond and use documents that people send me via e-mail or the web.

Advantage #3 - Runs on old hardware

If you have an old 386 or 486 laying around collecting dust, you can use this to run Linux. I remember running Linux just fine on a Pentium 100 with a 1 GB disk drive, and 16 MB of memory. One use of an old machine like that could be a file server. Just go to your computer store, buy a large hard disk (as long as your old stuff can support it), and you can make a great storage server. With all the digital pictures and movies around today, this could be a great use for Linux. Look into using Samba, a server application for Linux that allows you to make your machine share the disk as a Windows share.

Advantage #4 - Security

Linux has the advantage of the code being in the public domain. This can be a double-edged sword; while you can look at the code, and developers can fix holes rapidly, it also means hackers can find bad code. I have been very impressed with the security of Linux, and the programs that run on it. I think having the code out in the open, and the ability to fix things yourself if necessary is a big plus. Who likes to work blind? With some distributions, on installation the computer will ask you what levels of security you would like for your system. You can be very trusting, or you can be paranoid. Linux gives you this flexiblity.

Disadvantage #1 - Learning curve

I won't lie to you; Linux is going to take some time to learn. I know that our society likes to be instantly gratified. Learning Linux is definitely worth your time, but to really master it, you will need to spend some good time in front of your machine tinkering with things. Don't expect to be an expert after reading something like "Linux for Dummies". If you are contemplating this for your company, you will need to budget some money for training and learning time.

Disadvantage #2 - Equivalent programs

While I gave the example before of an office suite of programs that is working well, there are still applications that do not exist in Linux. Thankfully, this list has become much more narrow in recent months. You will want to think carefully when you switch to Linux about what programs you currently use, and if they have Linux support for them. It may not make sense for you to switch if you are going to spend tons of time converting databases and application data.

Disadvantage #3 - More technical ability needed

You will want to make sure that you train someone in Linux really well. Alternately, you could hire someone who has experience with Linux. A good Linux administrator needs to be on hand as you start to migrate your systems over. This is a disadvantage financially, at least in the beginning. You may find over time, however, that you only need a temporary administrator to handle the routine tasks.

Disadvantage #4 - Not all hardware compatible

Some of the latest and greatest hardware that is being produced is not compatible with Linux. At least, not yet. The people that contribute program code and drivers to the Linux kernel are great at including support fairly quickly. Until that time, not everything you buy for hardware in your system may work. I've had to rely on third-party drivers and other means to make hardware like a new Ethernet card work. Eventually, the support will be built in. One thing you can do is before your purchase, ask if the hardware vendor has support for Linux. Some manufacturers do write their own Linux drivers and distribute them with your purchase, making it very easy to integrate with your existing system.

Disadvantages of open source software

Are you or your organization planning to jump onto the bandwagon of “the open source software revolution”? In case you’re not aware of what is open source software it is supposed to be free software. Open source software can be modified by anybody and then redistributed because its code is supposed to be freely available, unlike the commercial software applications that you cannot alter and redistribute. The only caveat is that you cannot alter the open source software and then sell it commercially. Some prevalent examples of open source software are OpenOffice.org, a Microsoft office alternative, Ubuntu (a variant of Linux), a Windows operating system alternative, and Gimp, a Photoshop alternative.

So if all these alternatives are freely available why do people go for the commercial versions and spend so much money on non-free source software? Contrary to the popular beliefs the open source software is not as free as it seems. In fact sometimes it can prove to be more expensive than the commercial software. Here are a few reasons that caution most of the serious organizations to steer clear of open source software applications:

Most open source software applications are not reliable

Although big multinational companies like IBM and Sun Microsystems are backing the open source software movement there are no great financial stakes involved and the motivation mostly originates from a prevalent anti-Microsoft feeling. So there is no clear-cut discipline in this field and everything is emotion driven. Most of the developers and promoters of free source software believe in an obscure, idealistic world where intellectual property rights do not exist and software companies do not sell commercial software. Hence most of the applications are not reliable and you cannot run critical business operations on them.

No support exists for open source software

Once you decide to use open source software you are on your own. Agreed, that lots of help is available on the Internet and there are many self-motivated forums that can help you install and run open source software, there is no qualified support available. You have to figure out on your own how to install and use applications without sabotaging your data and hardware. For instance, every second kid in the neighborhood exhorts you to ditch Windows and switch to Linux; many have lost their years of data trying to make the shift. No help documents and manuals are made available since the software is being changed every second week.

Higher installation costs

It is a total misconception that you save money by switching over to open source software. More than 99% of PCs and laptops come with Windows operating system preinstalled and very few open source software applications adjust well with Windows. I don’t mean to say that once we are stuck with Windows we shouldn’t try another operating system; the incompatibilities are there just because nobody cares for the quality of the software. After the installation — if at all you can install it without destroying your digital resources — you have to put lots of effort into integrating the applications and make them give some decent output. Further, many open source software applications depend on the whims and fancies of the developers and they are not specifically developed by keeping the end user in mind; so once you decide to use it you have to really figure out how to excess various things. Sometimes even the menu conventions are not followed.

Another great problem is that most of the open source applications are incompatible with the present day gadgets. For instance if you use some open source operating system you can forget about the cool plug and play hardware that you have been using for so many years. Sometimes people can’t even get their modems working with open source operating systems.

Technical support too is costlier compared to commercial software because people who provide support for free source and open source software expect to earn lots of money providing support and in fact this is the only revenue model perceived in favor of the open source software movement.

No guarantee of updates

Since you are not paying for the open source software nobody is bound to give you regular updates. You can get stuck with the same old version for years without ever getting an update.
I wouldn’t like to paint the entire open source movement with a black color. Of course commercial software is sometimes too expensive and people who don’t have big budgets cannot afford them. Some buggy software is better than no software. For instance, OpenOffice.org with all its quirks is far better than Microsoft Office for those who cannot afford Microsoft Office and hence wouldn’t have such a product if it were not for the OpenOffice.org providers. Similarly there are many poor countries where low cost open source software can be used without incurring huge costs. But open source software shouldn’t be promoted as a commercial alternative.
