The market for open source and free software is surging high with its appreciation in mainstream segment also. The free software products like Linux or others are moving from the walled boundaries of servers to desktops and laptops. Recently, launched Ultra low cost laptops were supported on Linux and that came as a major breakthrough for it to garner some spotlight from tech analysts.

But still the concept of free software and open source software is not clear with many of us. We are confused at the basic level and interchanging the terms for each other. We use the terms Free Source and Open Source interchangeably and get them confused with the concept that they are available for free.

To some extent the concept gels with what we consider available for free but not in complete sense. The word free is basically the misnomer. We confuse it with free burgers but it should be considered for free speech. No doubt that some softwares from both the communities are available for free of cost and are offered as free downloads but not all utilities.

The two communities working with the aim of offering freedom to developers are working in the same direction but are literally and fundamentally different in their approaches. Till 1998, they were more or less same but after that the two movements separated with a different prospective, a different philosophy, and different motives.

The commonality in both the approaches is the open availability of source code to developers but the aim backing this approach is different with both the communities.

Where Free Software Community lays stress on providing source code to developers with the aim that user is free to do what he wish with the softwares source code. It is more philosophical in nature.

However, Open Source believes in offering source code to users with the aim that collaborative efforts can bring more subtle results. It has motivation that users can freely provide their suggestions for the source code and can append it to the existing one if results provided are efficient enough.

Both the communities lay stress on redistribution of code with no restrictions but the principles and motivations are different.

Where one seeks the liberty provided to users; the other targets the development of more efficient software programs with collaborative approach. Against the philosophical methodology of Free Software Community, the Open Source Community is driven by more practical reasons.

To some years the movements were working as a common alliance and Open Source was used as a marketing term for free software to reduce the ambiguity; but to worst it added more problems. So finally the two movements parted and started their own way.

Where the software developed by open source are more or less fits to zero-cost category, nothing like that can be defined for free software. To define it better, nothing which is free of cost can be a tailored fit for both the communities but cannot be turned off even.

Open Source is opposite to original context of Free Software. Free Software aims the freedom of users but Open Source aims the collaborative approach. The former stresses that users can freely see, modify and redistribute the code but latter has the approach that users can see the code but cannot modify it to suit its needs. In OSS, the liberty availed is in accordance of specific licensing agreements allowing one to fiddle with the code.

Free Software values freedom offered to users but Open Source believes in team development of software. Where one can be attached to social movement, the other is a development methodology. Both are against the patents and proprietary software, but cannot go hand in hand due to disagreement on certain principles.

To ask you, is GNU/ Linux is a free software or open source software Cannot answer surely; Linux is not an open source software but a product of free software community (as you are free to make modifications).

At crux, it can be said that both are different movements with differing principles but are fighting against the common objective Proprietary Software.

Superblock is the most significant component of a Linux volume that restrains critical information about files and folders in file systems as ext2, ext3 and more. It enables us to mount and access the file systems. Superblock corruption primarily occurs due to metadata structure damage, file system corruption, unexpected system shutdown, malicious software like virus and more.

In most cases of superblock corruption, the volume becomes unmountable and the data becomes inaccessible. In such situations, you can restore the lost data using an updated backup. However, if you have not maintained any backup or it is not up-to-date, then you need to recover your data by using advanced Linux Data Recovery tools.

Consider a practical scenario, when you attempt to boot your Linux system, you encounter the below error message:

“Wrong fs type, bad option, bad superblock on /dev/hda8, missing codepage or helper program, or other error. In some cases useful info is found in syslog – try dmesg | tail or so”

After running dmesg tail, you encounter the below error message:

“Couldn’t mount because of unsupported optional features (2000200)”

After the above error message appears, the system becomes unmountable and data stored on the hard drive volume becomes inaccessible. Additionally, you encounter the same error message each time you attempt to boot your system.

Cause:

The main reason behind occurrence of the above error message is superblock corruption.

Resolution:

To resolve the problem and access all inaccessible data, you need to follow these steps:

1. Boot your system by using an alternate block by running the below command:

e2fsck -b 98304 /dev/hdb8

2. Once the file system gets restored to the point at which it can be mounted, you need to fix it by using this command:

e2fsck -c /dev/hda8

-c parameter checks for the bad blocks

However, if the above steps are not able to resolve the issue, you should consider reinstalling Linux. A clean Linux reinstall will erase all existing data from the selected volume. For complete recovery of lost data, you should use efficient Linux Data Recovery software.

Such Linux Recovery tools incorporate effective scanning algorithms to recover all your lost data. These recovery tools provide highly graphical user interface that makes them easily understandable without prior technical knowledge. These tools recover data post situations like superblock corruption, group descriptor faults, inode table damage and more.

Stellar Phoenix Linux Data Recovery is the foremost Linux Recovery tool. It supports recovery from Ext2, Ext3 and ReiserFS file system based Linux volumes. This Data Recovery Linux tool gets installed on Windows (Vista, XP, 2003 and 2000) and the affected Linux drive is connected as slave.

When you are ready to search for a host for your web business online, there is a big dilemma that you need to seize by the horns: Linux or Windows?

In this context, it is easy to fall into the popular debate of which platform is better. Linux votaries may have a hundred brickbats to throw at Windows, and vice versa. Debates apart, what system is best for YOU? Many people take a decision depending on whatever platform is installed on their personal PC. This is rather short sighted. In short, there really is no need to take sides. Rather, the basic criterion for your selection should be based on what platform helps you the most. Real requirements of your site must be considered.

Windows web hosting: If your website uses any components or technologies that are Windows compatible, then it is advisable to go for Windows hosting plans. That way, you can easily run ASP, ASP.Net, MS Sql and other Windows scripting applications. Of course, these days it is possible to get Windows applications that are compatible with Linux server, but, to garner the full power of Windows, it is recommended that you go for a Windows based platform. If you are using additional services like Microsoft’s Sharepoint or MS Access, Windows platform is the only choice.

Linux web hosting: Linux servers are known to possess remarkable power and stability. If you use platform independent languages like PHP and MySql, you are better off with a Linux server. These servers are able to take the load of several simultaneous queries provided they are administered properly. Linux based databases like MySql and PostgreSql are relational databases. They are inexpensive and very efficient. Unless your server experiences very heavy load, these databases perform exceptionally well.

Linux servers have a reputation for dependability. This is because they often maintain a very high uptime of 99.9%. This is also one of the reasons for the compelling attraction of Linux website hosting servers.

Linux and its supporting technologies are open source technologies. Because of this, these are not expensive. On the other hand, Windows is developed by Microsoft at very high operative costs and Microsoft makes it mandatory to obtain their license before you can use the Windows server. This is why Windows systems are so expensive, while Linux is comparatively cheap. Additionally, Linux offers the greatest of ease when it comes to switching over to Windows system. Linux is also open to easy upgrades and can easily accommodate the changing requirements of the user.

To sum it up, Windows hosting plans are generally 20% costlier than Linux plans. So, if you do not need some unique features for your website like a searchable database or a chat facility, then Linux hosting servers perform beautifully and flawlessly. In the end, it all depends on what YOU want, not on the merits and demerits of the server.

Hey I want to know what kind of training will I need to use open source code from programs like Mame or Final Burn, emulators. If the rumor of the PS3 Hard Drive coming with Linux, I want to make a emulator in which people can play 4-6 player arcade games (with legal roms of course) on a TV through a PS3. I’m currently trying to get back in school to get a degree in Infomation Systems with a consentration in software, cause I want to become a game developer, but I want to start with using open source to see if I have the goods to make a good interface.
