What is Linux?
Monday, January 18th, 2010Linux – the operating system for a GNU (pronounced Gnew) generation. It has been dubbed the alternative to Microsoft, the solution to all life’s problems and many other things that may or may not be true. But what is Linux, and should you care?To answer the first question, it’s a free operating system that looks and acts very much like Unix. You can download it off the Net for free, or you can copy it legally from a friend – although this might take all the fun out of using that CD-Writer you’ve got and never use for anything, except to brag about it to your friends. Alternatively, you can buy it nicely packaged from an Internet store and get it delivered with a book about Linux, (Linux Unleashed). Distributors charge not for the operating system itself, but for their time in packaging and presenting it. Two popular flavors of Linux are Free BSD and Ubuntu. These offer the same basic systems with a few slight differences that can lead to long and entertaining godly wars between supporters of each. If you’re getting into Linux for the first time, Ubuntu is a good bet. You can either go for Ubuntu Desktop which comes with a GUI, or you can opt for Ubuntu Server if you planning to host websites of your own. The server edition has no GUI, but you can install KDE or Gnome to make your life easier. Most of your configuration will be done via the Terminal and you will have to learn a lot of Linux commands. Linux is more complicated, and it depends on the kind of person you are. If you’re the type of computer user who wants every application to run straight out of the box and your system to just do what it’s told and run your games, then stick with Windows. But if you’re a pioneering soul who wants to find out more about your system and tweak it to perform to the max, then Linux is definitely worth a try. If you want rock-solid Internet access, if you want to support the development of free software and more efficient solutions, or if you’re just the type of person who needs control over every aspect of your life including how your machine performs, then you’re definitely a Linux candidate. Linux is perfectly suited to students, developers and just about anyone who wants to try something other than the norm. Newcomers will find support straight off the Internet from thousands of kindred spirits. It’s worth a try – maybe you’ll discover a Whole New World of fun and adventure. Or maybe you’ll just take it straight off your machine and go back to Windows. However, if you planning to try it out, then load it on that old machine that’s just lying around in the basement. You don’t need powerful processors and hardware – the most important component is memory. If you have 512mb and a 20gig hard drive then you should be OK. You should be able to run all your applications including your websites with ease. Remember, you will need a permanent connection to the Internet if you going to host your own websites. The best part is that you don’t need any antivirus and antispyware software if you’re running Linux. Every would-be-virus-writer out there has only one target in mind – Microsoft Windows. Whether you stick with Linux or not, you’ll have come out of your safety zone and taken a trip to the cutting edge of computer technology.
Damn Small Linux Text Processing
Thursday, January 14th, 2010Damn Small Linux is an excellent tool for learning Linux commands and running the Linux operating system. But what if you don’t plan to be a computer nerd; can this software still be useful? The answer is a definite yes; you can make use of this tiny operating system whether or not you want to learn the sometimes gruesome details of operating systems. This article introduces the text editors that come with your free Damn Small Linux that runs on even obsolete Windows computers. You can use these applications to compose simple text or programs of any level of complexity.
Once you have downloaded and installed Damn Small Linux there are several equivalent ways of launching its text editors. You can click on the DSL button in the lower-left hand corner or on the Apps icon toward the top of the screen. Then open the Editors: there are four, Beaver, Nano, Notepad, and vi (actually vim). We will look at these editors in order plus an additional one.
Beaver is my choice for creating and editing the text files used in my Damn Small Linux tutorials. The name Beaver stands for Beaver is an Early AdVanced EditoR which is the kind of joke that many Linux and Unix people find funny. This editor is particularly useful for programming and web page editing. Beaver’s special features include color coding and the ability to convert text to Upper Case, Lower Case or to capitalize the first letter of every word. You can convert text among the following formats: Unix, DOS, and Mac. Programmers will be glad to know that Beaver formats code for the following programming languages: C/C++, HTML, Perl, JavaScript, PHP, and Bash. Unfortunately there is no Help function.
The nano program is especially used for email messages. It stems from the widely used Pico email program that is not available for some versions of Linux. I have not worked with nano but am told that many Linux and Unix people like it.
What the Damn Small Linux people call Notepad is actually another text processor that is similar to the DOS/Windows Notepad. I haven’t used it because Beaver is more powerful, and just about as easy to use.
The final application in this group is VIM, vi IMproved. The original vi was a very-widely used text editor for Unix and Linux systems. Today almost all Unix and Linux people work with other, more sophisticated text editors. When I teach Linux on systems other than Damn Small Linux I teach a reduced version of vi. This editor is cumbersome, but you make like the improved version. Damn Small Linux offers you a choice.
The Office folder includes Ted, a word processor which is compatible with Microsoft Word. Ted saves documents in RTF (rich text format) that can be read by Microsoft Word and other word processors including Open Office. Ted and Beaver belong to different worlds; you can’t take documents back and forth between these two applications.
