When it comes to security, versatility and stability, there is no better solution in information technology than open source. From operating systems to Web development to just about any common application, the open-source revolution finally has taken hold.

Businesses have started to truly understand the benefits of opting for open source, not only to save money, but also for the peace of mind it brings to their IT environment.

The term “open source” has a variety of meanings in the IT world. It is used to describe initiatives and collaborations ranging from software projects to enterprise environments with source code that is accessible to anyone. It stands as perhaps the ultimate example of the process of continuous improvement by encouraging everyone to make it better – and share how they did it.

Many open-source-based solutions like RedHat, Ubuntu and Suse are becoming down-right mainstream, drawing offers for proprietary partnerships from hardware giants like Dell, HP and IBM. So far, each has maintained its autonomy and reiterated its commitment to furthering “the movement” rather than its bottom line.

The issue of support no longer keeps businesses from buying in to open-source technology either. Most are fully supported, either through packages by their distributors, as in the case of RedHat and Suse, or via the well-rounded Internet network.

Open-source now is possible – and pragmatic – for every new Web development project. By using LAMP – that’s Linux, Apache, MySQL and PHP – an open-source solution can be created that is versatile and secure.

Pros and Cons of the Major Operating Systems

Posted by Dean Walden | Posted in General, How To, Ubuntu, distributions | Posted on 10-02-2010-05-2008

There are several options when it comes to choosing an operating system for your computer. Of course Windows is the overwhelming heavyweight in the market place and it isn’t a bad choice in some ways, especially for those not interested in the nuts and bolts of things. Also looking for users are Linux, BSD and Leopard.

1. Windows

The good side of Windows is that it is made to operate programs. The rich variety of software that works here is a huge selling point. You don’t have to be a programmer or even a techie to be a user. Everything comes from a disc or a download. Click the install button and away you go. Word processors, Spreadsheets, Games, Synthesizers, Photo Editors, Art Creators, Email Handlers, Bookkeepers and Website Makers are some of the most common. Then there are the not so popular yet also intriguing out of the mainstream volumes such as File Converters, Iso File Makers, Virus Hunters, Adware Killers and endless utilities you may discover once you start looking. There is a small utility that saves clips (as many as you want) that can be pasted anywhere so you don’t have to retype all the time.

That’s the good side of Windows. Just so you know it’s not all roses and candlelight you should know there are some drawbacks too. Everything you do on Windows should be backed up regularly. Why? Because just about the time your five week project is within a few paragraphs of completion, Windows will have a hiccup and lose the whole thing or some virus will erase your hard drive, or you’ll press the delete button accidentally. Boom, it’s all toast. Another thing about Windows is that it’s already programmed, you have to accept it as it is. If it doesn’t have a feature you need, you’re out of luck. If the button arrangement is not convenient (although there is some flexibility), you must adapt. Don’t need all the bells and whistles? Your stuck with them. Then there are the slow days when it all just seems to sit there and mock you taking it’s sweet time. It’s no wonder someone occasionally tosses one out the 10th story window.

2. Leopard

So, what are the other options? Well, first is Leopard which is the Macintosh operating system. Macintosh is made by Apple Computers. If you don’t know who Steve Jobs is, you must live in a dark and deprived world. Macs, as they are known, cost a little more than others systems (about twice the price of a Windows machine). I will tell you right here that I have yet to meet a Mac user that has a bad word to say about his or her machine. If you get one, you are practically guaranteed to love it. They are the choice of graphic artists almost universally. The local ad sheet for the city is made on them, so they make commercially viable tools.

The negative side. Not a lot really. There isn’t as much software made for them, but the ones you get are extremely well made. A lot of the less popular stuff doesn’t exist for Macs. That along with the higher price are the main hitches.

3. Linux

Another option is Linux. The Linux operating system is actually free at this time so the price is right. There are many flavors (versions) of Linux, so you don’t have to use the same thing everyone else has. Some that I know of are:

* Red Hat
* Ubuntu
* Suse
* Damn Small

Each one has advantages and limitations because they are geared toward a certain area such as games or internet or servers. They have a ways to go to become popular, yet are making great strides in market share. Also, if you can do the programming, Linux offers wonderful access to the code. In the last year or so, it has become quite easy to obtain and install Linux on any computer. In fact it will coexist right alongside Windows, so now there is little excuse for not trying it out. They offer a GUI similar to Windows and Leopard which is fairly intuitive. Some software is quite comparable to the bigger fish. OpenOffice will take Office on and come through looking pretty good. Gimp has a learning curve, but can do much of what Photoshop does for free.

The downside is that Linux is just not as developed. It is a terrific platform for geeks that love to swim through code and troubleshoot glitches. The creative potential is unlimited which is the main drawback at the same time. Most people want something ready to go, not something they have to create before they can operate. The number of programs (though growing) is quite limited.

4. BSD

The last of our operating systems to consider is BSD. Just like Linux, it is free (though there is a commercial version). The major selling point is that it is the most modern system. It doesn’t have the backward compatibility issues of Windows. So many advances in hardware have been made since windows was introduced that you wouldn’t believe some of it. BSD was created to take advantage of these advances. It has the most potential of all these systems because of it’s modern design. It is quite compatible with and similar to Linux, just more modern.

That at the same time is it’s largest problem. Most of the accessories that go with an operating system (software and interface) are lacking at this time. It’s like having a Ferrari engine and framework without the rest of the drive train.

Linux Distro and Desktop – The More the Merrier, Right?

Posted by Ashok Ramachandran | Posted in General, distributions | Posted on 09-02-2010-05-2008

Isn’t it great that the open source world gives you a lot of choices? When it comes to Linux distributions, shortly known as distros, there are hundreds of them. Once you have selected a distro, you are up against a decision regarding the desktop. You need to know enough about the pros and cons of these choices so that you can pick the one that is right for you.

Let us briefly revisit the requirements for a successful migration.

You have to meet three requirements before installing Linux on your home PC:

  1. You have identified a demonstrable benefit you can gain by migrating to Linux
  2. You have done your prep work
  3. You have realistic expectations

By following these three steps, you will maximize your chances of success.

However, there is a mind boggling variety of Linux distros available.

Let us try and shortlist the Linux distros based on the following five criteria:

  1. Is it backed by a commercial vendor?
  2. Is desktop Linux for home a stated focus area for this vendor?
  3. Is a retail product available in the form of a CD/DVD?
  4. Are branded PC vendors shipping this distro pre-installed?
  5. Is paid support available, if needed?

We find that there are only two Linux distros that meet these five qualifications largely – Ubuntu and SUSE Linux.

Ubuntu

  • Sponsored by Canonical.
  • You can download it free, buy it on DVD from Amazon or get a free CD shipped (takes 6 to 10 weeks).
  • Starter support for Ubuntu Desktop Edition is available for one year at $ 54.99 (as of Sept 2009).
  • Security update is available for 18 months from release.

SUSE

  • Sponsored by Novell.
  • You can download it free, buy it on DVD from Amazon.
  • You can buy a package from Novell consisting of a DVD with printed manual and 90-Day installation support (by phone or e-mail) for $59.95 (as of Sept 2009).
  • Security update is available for 2 years from release.

Can I buy Linux pre-installed from a branded PC vendor? Dell offers PCs for the home and home office market pre-installed with Ubuntu Linux. HP and MSI offer PCs with Novell SUSE Linux Enterprise Desktop pre-installed. Asus offers notebooks with Xandros Linux pre-installed. Acer offers notebooks with Linpus Linux.

Can I get Linux pre-installed from another vendor? Zareason, Berkley, CA and System76, Denver, CO sell Ubuntu Linux desktops and laptops.

Which desktop? Though there are other options available, we will restrict our selection to the two leading desktops, namely GNOME and KDE.

GNOME

  • GNOME is a very mature and stable desktop.
  • The GNOME project has well defined human interface guidelines to make the desktop and applications easy to use. Most GNOME applications follow these guidelines, resulting in common usability between applications.
  • GNOME doesn’t provide a graphical interface for some of the settings. Users will have to use the command line interface for these.

KDE

  • KDE is also a very mature desktop. However, KDE 4 was completely rewritten and so had some issues. The recent 4.3 version seems to be more stable.
  • KDE is also better for new users switching from Windows, and relies less on the command line interface.
  • Unfortunately, KDE does not use Firefox as the default web browser or OpenOffice as the default office suite. You will have to install Firefox and OpenOffice subsequently.

If you are planning to use an older machine and just require stability and an uncluttered approach then you can go with GNOME. However, if you have a newer machine, looking for a desktop closer to Windows and avoid the command line interface, then KDE is your best bet.
