Introduction

However, most of the successful projects were run using fairly heavy-weight methodologies, CMM or ISO accredited, for example. Extreme Programming promises to deliver the benefits while still being simple. I was sceptical. This sounds a little too close to one of Fred Brookes Silver Bullets.

Introduction

I have a terrible confession to make. I am not a spiritual man so, rather than seek penance through the church, I shall document my reasoning here on the web and you can make your own conclusions.

Please go easy on me.

My confession: I can see myself buying a Macintosh later this year.

To some, that may not sound like something to be ashamed of but it’s all a matter of perspective. By trade and education I’m an engineer or scientist; I have short hair, no piercings and virtually no artistic ability (I present the evidence of that here on this web site!). My computer of choice tends to have a barren, baroque user interface. Let’s be honest here, it’s Unix.

Introduction

Talking about C is not easy. Almost all professional programmers have used it at some point and many have a strong attachment to it. I don’t want to start by saying that it’s a poor language, alienating much of my audience, but I figure I’m going to end up doing that anyway so I may as well get it out of the way at the beginning.

Compared to many languages that have come since, and even some that came before, C just isn’t a very good language.

Introduction

PL/SQL is good for many things. It has a structured, Ada-like syntax and can have SQL statements seamlessly embedded in it. Although not compiled right down to machine code, it’s even fairly quick.

But one thing that most people initially have difficulty doing is displaying information on the screen. The first thing I did was to enter what I wanted into a temporary table and use SQL*Plus to select from it. This works well for reports at the like, but it doesn’t work at all if you want to display something independently of a transaction or halfway through a function.

With the current Linux trend towards multi-million dollar IPO’s and “Open Source” software, much of the emphasis of “free” software has been lost leaving people new to the fold confused and not completely understanding all the implications. This HOWTO will, hopefully, reduce some of that confusion.

## Introduction

What’s in here?

This document talks in non-technical terms about free software, what it means and why you should care about more than just the cost of your software.

Edward Yourdon is a well known and well respected computer scientist, so what useful information can he give you in these circumstances? Surely you’re lumbered with the simple choice between putting up with it or resigning?

Introduction

Many developers would hate to have their master-work described as a mess, but not Larry Wall, creator of Perl and celebrity hacker. The way he sees it, the language is a mess because the problem domain — real life — is also a mess. He has a point.

I first came across Perl a few years ago when I was writing a program that required a certain amount of ‘screen-scraping’ from a telnet session, the ability to retrieve files using FTP, some complex processing and interaction with an Oracle database. This is a fairly messy problem, and one that Perl looked eminently able to solve.

It is now two days after Microsoft’s official release of ‘the next generation’ of their premier operating system, Windows 2000 (n?e, NT5). We’re now at a safe distance to be able to assess the impact it has had on people and the press.

The first interesting thing to note is that on Slashdot, the Internet’s favorite site for hacker-oriented hi-tech news, did not make any announcement. One argument is that Slashdot is Linux, or at least Unix, biased making Windows news irrelevant. I don’t buy that. What Microsoft is doing is important if Linux is to achieve world domination.
