For a brief moment I was famous on Wikipedia! They removed me pretty soon after I add myself….
I was Googling random topics today. One search was for “Jaws” because wouldn’t it be cool if they made a sequel that actually lived up to the Jaws name… they’re making a Jurassic Park sequel to be released in 2015. When searching for this, I found there is a web framework project named after the famous movie… go figure.
I am amused.
Yesterday, my post included a reference to Jurassic Park where the little girl made a comment about Unix systems. Cool fact, they actually used a real 3D file system Unix navigation tool for the movie. A SGI Crimson system with the fsn three-dimensional file system navigator, to be precise, appeared in the movie (sgistuff.net)
I was thinking, it must be cheaper for films to use open-source software over expensive things such as Windows. But, the Unix OS is an enterprise operating system found in universities and large companies for the most part. Yes, there are some Unix distributions that are open-source. Linux on the other hand is all open-source (however some distributions request a fee for premium help services). They are both very similar, Linux was created as a free alternative to Unix and is based off of the OS (so is OSX, which is why I like it). Many of the tools developed for Linux were also created as free substitutes to Unix tools.
So what are the differences between the two? This site and this explanation by IBM provide more detailed comparisons of the two, I’m just going to highlight on how proprietary versus being open-sourced has affected the development of the two and contributed to their differences.
|History||Unix dates back to the mid-1960s. MIT, AT&T Bell Labs and General Electric joined forces to collaborate on a new system. Their first production of Unix was released in 1972.||Inspired to be a free alternative to Unix. Dates back to the GNU project creation in 1983. GNU standing for “GNU’s not Unix.”|
|Hardware||Limited to architecture, the OS is normally customized/optimized specifically for the hardware||Very flexible|
|File system||Supports a limited number of file systems typically of JFS, GPFS, HFS, HFS+, UFS, XFS, ZFS format||Supports almost all file systems currently available to any operating system, popular ones include:Ext2, Ext3, Ext4, JFS, ReiserFS, XFS, BTRFS, FAT, FAT32, NTFS|
|Development||Well documented with published standards for development||Anyone can join in and contribute without any real restrictions, hence open-source. Not everything is always well documented, depends on the developer’s mood|
|Testing||Highly tested||Not as much|
|Applications||Limited, however, the tools/applications are consistent across distributions||Vast library of applications because the developer community is huge but it is not always consistent|
|Bug Fixing||Bugs aren’t as common but like any proprietary system, it takes time for a patch to be released||The open-source community is vast and developers scrutinize over each other’s work (this often leads to fast bug patches)|
Clearly, being open-source provides a different development community that aids to a much broader range of usage and users. With this main difference between the two, each has been shaped differently. Unix is consistent and sturdy while Linux is flexible and all over the place.
