+ With very little argument, starting a project is most difficult
+ part of successful free software development. Laying a firm
+ foundation for your project will determine whether your project
+ flourishes or withers away and dies. It is also the subject that is
+ of most immediate interest to anyone reading this document as a
+ tutorial.
+ </para>
+
+ <para>
+ Starting a project also involves a dilemna that you as a developer
+ must try and deal with. No potential user for your program will be
+ interested by a program that doesn't work. Simultaneously, the
+ development process that you want to employ holds involvement of
+ users as essential to the process of the development that will
+ realize this working software.
+ </para>
+ <para>
+ It is in these dangerous initial moments that anyone working to
+ start a free software project must strike a balance. One of the
+ most important ways that omeone trying to start a project can work
+ towards this balance is by establishing a framework for the
+ development process through some of the ways mentioned in this
+ section.

<title>Choosing a Project</title>
+
+ <para>
+ If you are reading this document, there's a good chance you
+ already have an idea for a project in mind. Chances are pretty
+ good, it fills a gap by doing something that no other free
+ software process does or or does it in a way that is unique
+ enought to necessitate a seperate project.

+ <title>Indentify and Articulate Your Idea</title>
+ <para>
+ Eric S. Raymond writes about how free software projects start in
+ his paper, "The Cathedral and the Bazaar" which comes as required
+ reading for any free softare development. You can find it online
+ at <ulink url="http://www.tuxedo.org/!esr/writings/cathedral-bazaar/">
+ http://www.tuxedo.org/!esr/writings/cathedral-bazaar/</ulink>.
+ </para>
+
+ <para>
+ In "The Cathedral and Bazaar," Raymond tells us that:
+ <emphasis>Every good work of software starts by scratching a
+ developers itch.</emphasis> Raymond now widely accepted
+ hypothesis is that new free software programs are written, first
+ and foremost, to solve a specific problem facing the developer.
+ </para>
+
+ <para>
+ If you have an idea for a program in mind, chances are good that
+ it it is targetting a specific problem or itch you want to see
+ scratched. <emphasis>This idea is the project. Articulate it
+ clearly. Write it out. Describe the problem you will attack in
+ detail. The success of your project in tackling a particular
+ problem will be tied to your ability to identify that problem
+ early on. Find out exactly what it is that you want your project
+ to do.</emphasis>
+ </para>
+ </sect3>
+
+ <sect3 id=evalulateidea>
+ <title>Evaluate Your Idea</title>
+
+ <para>
+ In evaluating your idea, you need to ask yourself questions.
+ Before you move any further into this HOWTO, you need to
+ determine if the free software development model really is the
+ right one for your project. Obviously, since the program
+ scratches your itch, you are definately interested in seeing it
+ implemented in code. But, because one hacker coding alone fails
+ to qualify as a free software development effort, you need to ask
+ yourself the question: <emphasis>Is anybody else
+ interested?</emphasis>
+ </para>
+
+ <para>
+ Sometimes the answer is <emphasis>no</emphasis>. If you want to
+ write a set of scripts to sort <emphasis>your</emphasis> MP3
+ collection on your machine, maybe the free software development
+ model is not the best one to choose. However, if you want to
+ write a set of scripts to sort <emphasis>anyone's</emphasis>
+ MP3s, a free software project might fill a useful gap.
+ </para>
+
+ <para>
+ Luckily, The Internet is a place so big and diverse that, chances
+ are, there is someone, somewhere, who shares your interests and
+ how feels the same itch. It is the fact that there are so many
+ people with so many similar needs and desires that introduces the
+ second major question: <emphasis>Has somebody already had your
+ idea or a reasonably similar one?</emphasis>

+ <title>Deciding to Proceed</title>
+ <para>
+ Once you have successfull charted the terrain and have an idea
+ bout what kinds of similar free software projects exist, every
+ developer needs to decide whether to proceed with their own
+ project. It is rare that a new project seeks to accomplish a
+ goal that is not similar to related to the goal of another
+ project. Anyone starting a new project needs to ask themselves:
+ <emphasis>Will the new project be duplicating work done by
+ another project? Will the new project be competing for
+ developers with an existing project? Can the goals of the new
+ project be accomplished by adding functionality to an existing
+ project?</emphasis>
+ </para>
+
+ <para>
+ If the answer to any of these questions is yes, try to contact
+ the developer of the existing project in question and see if he
+ or she might be willing to collaborate with you.
+ </para>
+
+ <para>
+ This may be the single most difficult aspect of free software
+ development for many developers but it is essential. It is easy
+ to become fired up by and idea and be caught up in the momentum
+ and excitement of a new project. It is often extremely difficult
+ but it is important that any free software developer rememeber
+ that the best interests of the of the free software community
+ and the quickest way to accomplish ones own project's goals and
+ the goals of similar project can often be accomplished by
+ <emphasis>not</emphasis> starting a new project.

- <para>
- In most distributions of Linux there is a document directory
- installed, have a look in the <filename>/usr/doc</filename>
- directory. where most packages store their main documentation and
- README files etc. Also you will here find the HOWTO archive
- (<filename>/usr/doc/HOWTO</filename>) of ready formatted HOWTOs
- and also the mini-HOWTO archive
- (<filename>/usr/doc/HOWTO/mini</filename>) of plain text
- documents.
- </para>
-
- <para>
- Many of the configuration files mentioned earlier can be found in
- the <filename>/etc</filename> directory. In particular you will
- want to work with the <filename>/etc/fstab</filename> file that
- sets up the mounting of partitions and possibly also
- <filename>/etc/raidtab</filename> file that is used for the
- <Literal remap="tt">md</Literal> system to set up RAID.
- </para>
-
- <para>
- The kernel source in <filename>/usr/src/linux</filename> is, of
- course, the ultimate documentation. In other words, <quote>use
- the source, Luke</quote>. It should also be pointed out that the
- kernel comes not only with source code which is even commented
- (well, partially at least) but also an informative
- <filename>/usr/src/linux/Documentation</filename>. If you are
- about to ask any questions about the kernel you should read this
- first, it will save you and many others a lot of time and
- possibly embarrassment.
- </para>
-
- <para>
- Also have a look in your system log file
- (<filename>/var/log/messages</filename>) to see what is going on
- and in particular how the booting went if too much scrolled off
- your screen. Using <command>tail -f /var/log/messages</command>
- in a separate window or screen will give you a continuous update
- of what is going on in your system.
- </para>
-
- <para>
- You can also take advantage of the <filename>/proc</filename>
- file system that is a window into the inner workings of your
- system. Use <command>cat</command> rather than
- <command>more</command> to view the files as they are reported as
- being zero length. Reports are that <command>less</command> works

- In the end you might find yourself unable to solve your problems

- <para>
- Another possibility is to ask on Usenet News in one of the many,
- many newsgroups available. The problem is that these have such a

- No matter where you ask it is important to ask well or you will
- not be taken seriously. Saying just <emphasis remap="it">my disk

- Q:How many physical disk drives (spindles) does a Linux system need?
- </para>
-
- <para>
- A: Linux can run just fine on one drive (spindle). Having
- enough RAM (around 32 MB, and up to 64 MB) to support swapping
- is a better price/performance choice than getting a second
- disk. (E)IDE disk is usually cheaper (but a little slower) than
- SCSI.
- </para>
- </listitem>
-
- <listitem>
- <para>
- Q: Are there any disadvantages in this scheme?
- </para>
-
- <para>
- A: There is only a minor snag: if even a single partition
- overflows the system might stop working properly. The severity
- depends of course on what partition is affected. Still this is
- not hard to monitor, the command <command>df</command> gives
- you a good overview of the situation. Also check the swap
- partition(s) using <command>free</command> to make sure you are
- not about to run out of virtual memory.
- </para>
- </listitem>
-
- <listitem>
- <para>
- Q: OK, so should I split the system into as many partitions as
- possible for a single drive?
- </para>
-
- <para>
- A: No, there are several disadvantages to that. First of all
- maintenance becomes needlessly complex and you gain very little
- in this. In fact if your partitions are too big you will seek
- across larger areas than needed. This is a balance and
- dependent on the number of physical drives you have.
