I have discussed about Linux in several article previously, yet the history are not yet mention, so in these article, lets have a look at glance history of Linux Operating System.

The development of Linux are closed with UNIX as reliable operating system during that time. Unix which are developed by Ken Thompson and Dennis Ritchie in the late 60′s have formed hacker culture on the 1980′s. The hacker culture during that time is identical with figure Richard Stallman, from Artificial Intelligence Lab at MIT. He and latter hacker community believe sharing source code and knowledge will eventually increase the development of the software itself.

In the mid-1980s, Stallman formed the Free Software Foundation (FSF) to encourage free software development. Most of his community are colleges and student on university whom ran UNIX as their operating system and work environment.
From these year the GNU project are started.

Linus Torvalds a Finnish student if the first person whom experimenting with Linux development in 1991 with Intel x86 which became standard home and business hardware platform during that time. And these is the first time Linux published under GNU GPL.

Starting from there numbers of software developer have release new improved and reliable Linux kernel system that have interest amount of companies and users. These action have made many version and distribution of Linux collection, lets see, Red Hat, Mandreake, and Suse.

Right now, the distribution or we often sort it as Linux distro have evolve into numbers of version, some even made by local software developer.

Yet, Red Hat Linux would the Linux distro which being widely use around the world. The second one is Suse Linux. Slacware, Debian, ubuntu, and Turbo Linux shares the rest of the chart Linux distro.

Reasons why Linux are chosen as priority Mon, 27 Aug 2012 10:11:21 +0000

Among many reasons why user and companies using Linux as their first priority, its open source function would be the dominant reason.

As for other consideration, major big companies, such as Google with their Android OS, IBM, HP, Intel, Dell, etc. have use it as well.

Ordinary reason such as security reason such as its safer using Linux then other OS since Linux have less attack then others. Not too mention its flexibility on many different hardware platforms and easiness on customization.

Companies might need latest software specifically for their daily routine activity. For these purposes, meeting latest technology, consumer need with market competition could effect on their business. With the same reason, updating the software is the only option they have, while with Linux, the company cost are able to be control more better other than using closed source software which requires additional budget for update the software.

If you look at the current situation, most of those major application software solution able to run in many different kind of operating system, Linux is one of it. Yet for their new release of software, it requires stable and latest operating system to run the software properly.

Lets have a look at security issues, Linux are consider as one of less operating system attacked by viruses and worms. To prove my point, lets have a look at the fact that on 2008, Linux have less then 100 known viruses, compare it with Windows for example, it had more than 1,000,000 known viruses.

And don’t forget the fact that some or even most of Linux user installing Linux under other operating system (Windows), these means that Linux installation files are sharing with Windows folders, which might reasons when host files infected with worms or viruses, the inside files might also infected as well.

Lets talk about the compatibility of the Linux OS, Linux are able to run in most hardware platforms. Just mention it, Intel x86 and x64, Itanium, Alpha, Mainframe, Itanium, even SPARC and UltraSPARC system.

With these fact its hard not to use it as priority operating system.

Linux Licenses Mon, 27 Aug 2012 09:46:01 +0000

You might have know that Linux is under GNU GPL (Generic Public License) which developed by Free Software Foundation. Just for your information GPL meaning that the source code of these software are freely open. Its also mean despite some person might have modify the source code for their own purposes, still they should redistribute the source code freely. These action could kept the source code stay free for life time.

As for GNU stands for GNU’s not UNIX, to understand it, you might need to take a look at Linux history. As its first release, Linux are meant to get UNIX version of Operating System but free.

Don’t get mixed with freeware and shareware, these two type of licensing are belong to closed source licenses. These two type of licenses are freely distributed and free of charge, but, the source code is closed. And then the other one is shareware, similar to freeware, yet for the source code, you could get it, but you they will charge you for it.

So now you should know it better that Linux is open source software.

Because of its open source, Linux are often chosen as companies operating system priority. Unlike their competitor, which have support team, Linux have community of software developer for discussing some bugs issues.

Since Linux is an Open source Operating system, other software developer able to read other developer source code, modifying it, and use it as he or she likes.

If you do worry about the future of Linux OS since its support are based on community, don’t worry, some top company such as IBM, DELL, etc. have decide using Linux as their server, so why don’t we.

These open software fact, might create question on your head, if its free distributed, then how could then they get some profit for releasing the new and latest version of Linux. The answer is simple, the companies get their revenue from selling the hardware for supporting the operating system or it could be more further with developing software that is closed source license that runs in Linux.

Hope that’s explain enough about Linux Licensing.

Basic command in FreeBSD Fri, 24 Aug 2012 09:36:46 +0000

What is FreeBSD, freeBSD is one of linux distro being launch several years ago. FreeBSD is quite popular operating system cause its freeware under GNU license.

Despite its quite common command, yet, if your a new beginner on FreeBSD, you might confuse of what will you do after doing some OS installation.

In order to help you with it, lets discuss it one by one as described below:

Start it with login with user “root”, input the password, and follow below basic command.
# ‘cd’ = change directory
# ‘ls’ = list (listing all file inside the directory)
# ‘rm’ = remove (remove or deleting the file)
# ‘mkdir’ = make directory
# ‘clear’ = clear all command on the screen
# ‘ps’ = processing status (viewing active process on the system)
# ‘kill’ = stop or kill a process
# ‘cp’ = copy
# ‘whoami’ = its sort of help file on what are we doing in the process
# ‘pwd’ = to know whether we inside directory or not
# ‘tar’ = extracting compress file (tar.gz)
# ‘compress’ = compress files
# ‘whereis’ = to know where the file located in
# ‘mv’ = move or change file into other directory
# ‘passwd’ = changed command on access password
# ‘ee’ = easy editor (similar with type editor application)

Basic difference of MySQL and Oracle Fri, 24 Aug 2012 08:16:37 +0000

Okay since now MySQL is being owned by Oracle, then what would be the difference within these two instead of its capability in handling numbers of clients and data, lets have a look it below.

First you should know that MySQL despite its compatibility of all major operating system, its best match is with Apache web server which are better worked in *nix environment.

If you disagree with me, its alright, but you might want to reconsider it when you see the super user administrator in MySQL are best known as “root”, similar with super user in *nix environment isn’t it.

Okay lets have a look at command, as I have described in previous article, the difference are obvious in MySQL, a semicolon after end of SQL command. These is crucial command required in MySQL.

Okay, lets take a look more further, which is more important, the framework. In ordinary database creation in Oracle, whenever you create a database, the main structure would be database -> scheme -> table.

While in MySQL its much more simple, only database and table. Each of user should be added for privilege access of the databases. Usually you could do it with simple command of “grand”.

Of course with “root” privilege, you will be able to access all of your databases.
