Introduction You probably already have Perl if you are running Linux or OS X. However, it is usually not the latest version of the language. I prefer to install my own copy. That way I can take advantage of new language features. Also, the system Perl is often used in administrative scripts. There is always the chance that my experiments will mess something up. It is not easy, but I have done it before.Aug 23, 2011

I have been dabbling a lot with Moose, a solid framework for object oriented programming in Perl. It is remarkably powerful and has transformed the way I look at Perl OO. It is also different enough from object oriented programming in other languages that I needed to create a section for it on coolnamehere.

Introduction If you have never programmed before in your life, then do I have the perfect programming language for you. It’s called Python. It is easy to learn, flexible, and loaded with capabilities that you never thought would be so easy to use. Imagine your thrill when you write a complete program in just a few lines! If you have spent years programming Perl, and are just about sick of all of the weird little context dependencies (“My function does this when you hand it a single object, and that when you hand it a list, unless you are assigning the result to a list, in which case it does this other thing”), then do I have the perfect language for you.Parrot Babysteps 0e - Parrot Namespaces

One of my big projects over the last year has been a Parrot Babysteps tutorial. One of the more interesting tasks in that tutorial was reading a CSV file in Parrot. I used the HYG Star Catalog as a sample CSV file that was large enough to present some interesting data. This was fun in Parrot, but obviously I thought quite a bit about how I would tackle the problem in a higher level language such as Ruby. Today seems like a good day to find out.

I want to learn Rakudo. You might want to learn Rakudo. Let’s spend a little time looking at how to get started. While I follow the same very simple pattern of other Babysteps on this site, I don’t expect Rakudo to be your first language. I won’t spend as much time explaining what’s going on, at least not on my first pass through these steps.Rakudo Babysteps 01 - Starting With Rakudo

Installation You will obviously need to install Rakudo if you want to use it. There are a couple of options, but I will focus on Rakudo Star. Rakudo Star is a distribution which includes some important libraries and an excellent book. Rakudo is released every month, so some of my details about version numbers may be a little off. I will do my best to stay caught up. Fortunately, my Babysteps are so basic that new releases have little effect on their value.Sep 8, 2010

The Perl world has evolved over the years. Once upon a time, it was a simple glue language that made life easier for system administrators. It’s grown up a lot since then, and now powers much of the Internet. The language has added new features, and the CPAN has made a dizzying number of libraries available.

Parrot is more than just PIR and PASM. I’m not talking about the ability to use languages like Rakudo written for the Parrot virtual machine. I am also not talking about the ability to write your own language. Both of those are quite nifty, of course. It is fair to say that those two items are probably why you are experimenting with Parrot in the first place. However, the Parrot distribution also ships with an extra language: NQP.

Parrot is a virtual machine that provides the base for Rakudo and a large number of other languages. I honestly can’t tell you what its virtues are compared to other virtual machines, because I’m just not that well informed. I have been exploring PIR, the Parrot Intermediate Representation language. It’s a lot more low level than what I’m used to, but it is still a lot of fun to play with.Parrot Babysteps 02 - Variables and Types

Having a program that displays the exact same message every time you run is nice when it comes to being consistent, but not so entertaining as a program. “What does it do?” “It prints out my name.” “Oh.” Let’s make things a little more interesting. We could change the value of
$namein the code, but it might be a little tiresome to do this before showing it to each new person. How about making the program ask for a name? User interaction - a neat idea.Oct 29, 2007 (Updated Jul 11, 2009)

There is more than one way to experiment with Ruby. JRuby is a mature version of Ruby written for the Java Virtual Machine. This gives you a great deal of platform independence, since JRuby will comfortably run anywhere that Java runs. It also provides you with access to Java’s huge standard library. I thought I would take a little time to examine the Jruby implementation, which is nearing a 1.0 release.

This is the second part of an ongoing series about using Python to create interactive fiction. I hope to show you one fun use of Python while teaching you more about the basics of this language. We started by defining how our game was going to work and creating a set of scenes for play. Next we wrote the code to handle a single round of the game. Today we are going to tie all of our scenes together to make a complete, playable game of interactive fiction. We are going to approach it from an experimental view, playing with different approaches until we find one that makes us happy. Well, one that makes me happy.

Sometimes it’s helpful to have multiple consoles open. The best example I can think of is when you are logged in to a machine via
ssh. There are other ways, of course. You could try to log in to the server with ‘-X’ so that X11 applications can run on the remote host but display on your computer. That’s not always easy, though. The administrator of the server may not allow X11 forwarding. Your machine may not allow or even understand X11 requests. You could log in to multiplesshsessions. This is what I did for several years. It works, but it’s not the most convenient approach, since it clutters up your desktop.screenis a better option.Reduce, Reuse, Recycle in REBOL

A mountain of standards and specifications have piled on top of XML over the years, but the core language is still pretty easy to get started in. Because it is a markup language rather than a programming language, there aren’t as many new concepts to learn. If you’ve learned HTML in the past, then XML will be familiar.

XML is the core language of the Web. It forms the foundation for nearly everything you read with your browser. You might not know this, though, because of the great number of languages and acronyms you find. Web pages are written in XHTML, news feeds are written in RSS, and many applications communicate to each other with XML-RPC. If you use Google Talk, then you are relying on the Jabber protocol. What do each of these languages have in common? They are all XML languages.

REBOL is the “Relative Expression-Based Object Language”, and it was developed by Carl Sassenrath. Who is Carl Sassenrath? Why, he’s one of the people responsible for the amazing operating system which powered the Amiga computer. What’s the Amiga? Why, the Amiga was only the incredibly robust and cool computer released by the same company that brought the world’s first personal computer, Commodore. What’s Commodore? Stop bothering me, kid. Just take it from a relative old-timer: the Amiga put a whole heck of a lot of power into a consumer-affordable personal computer, and it wasn’t really matched by other computers for a good five or ten years. Nowadays, I look at REBOL and it feels like the first language I’ve come across to take lessons from past languages and apply them in a new context, rather than just reimplement them with different syntax.

One of REBOL’s strengths is the rich selection of native datatypes. This selection is part of what makes it so easy to express solutions to your problems, because there is less “mental mapping” to make as you use or create an abstract type to represent an important concept. Learning this selection is also one of the challenges for those who are trying to master the language. I am facing that challenge right now, so I decided to make this table of native REBOL datatypes and how they are expressed.

This is unusual. I’ve come across the first language that I don’t want to tell you about. I don’t know why I want to keep REBOL a secret. It has been very useful even in the limited roles that I have given it so far. The language is consistent and pleasant to work with. It has a richness of datatypes that just can’t be matched by other languages. The GUI library, View, is surprisingly straightforward for simple tasks, and there are excellent libraries like RebGUI to make it just as easy for more elaborate interfaces.

People who come to UNIX (or Linux) from the world of Windows are often disappointed by the apparent clunkiness and lack of unified tools. “Where’s Visual Studio? Where’s C++ Builder? Heck, Notepad would be nice.” These folks are looking all around for an IDE, or Integrated Development Environment. What they don’t realize is that UNIX is an Integrated Development Environment. You can’t get around the fact that this environment was made for geeks, by geeks. That means a lot of the programs that seem so clunky and awkward to the Windows person are, in fact, intended to work together to make development easier.

There are several different approaches to programming, but the one that is easiest for me to grasp is imperative programming. The imperative approach allows you to tell the computer exactly what you want it to do and how you want it done. The best analogy I can think of is a cooking recipe. You have a list of ingredients and a specific set of instructions to follow. Veer from the recipe and you may not be happy with the results. Veer too far from the recipe and your house could burn down.

I’ll admit it. When I first got into Web programming, JavaScript was not my favorite language. It took too much work to get anything done, and then it wouldn’t work half the time on other browsers. That’s the other thing. It was only useful to most of us on Web browsers. Perl was funny-looking, but worked on nearly any machine and could make the most elaborate Web applications that worked regardless of what browser your visitor was using. You could even write applications that had nothing to do with the Web, using Perl/Tk and CPAN.

PHP is great. It is easy to learn and easy to use. Of course, it is also easy to make a project that is so amazingly baroque that mere humans have no chance of ever editing it.

It can be funny to listen to an argument between PHP and Perl folks about why their favorite is the best and the other guy is the worst. The other guy is always “unstructured and unsuitable for real projects”, while the favorite is “fast and expressive”.

Loads of new features were added by Greg Millam in short order, and testing / streamlining was completely derailed by daily life. I've been promising to work on PageTemplate 3.0 for years. Introduction PageTemplate is a Ruby package which allows you to utilize text templates for your Web projects.PageTemplate - If, Else, and Elsif

If The if directive tells PageTemplate to only display a chunk of content when some condition is true. PageTemplate will skip the block and move on if the condition is false. Syntax [%if condition%] chunk [%end if %] Here is an example of if in use. #!html [%if pageowner %] <a href="admin.cgi">Admin View</a> [%end if %] In this example, if the application tells PageTemplate that pageowner is true, PageTemplate inserts a link to an administrative page.Jun 2, 2002 (Updated Jul 11, 2009)
Loop Basics The loop directive is the most complex, and requires more explanation of its details. Let’s start by just looking at the basic syntax of a loop in PageTemplate. Loop Use the loop directive when you want PageTempate to insert the same chunk repeatedly for a list of items. It can grab values from the item to be inserted in value directives within the chunk. If there is no list of items, the in chunk is skipped.Jun 2, 2002 (Updated Jul 11, 2009)
PageTemplate has a number of other features for the designer, and I couldn’t figure out where to put them. Let’s just dump them here until the day I do figure out where a good spot for them would be. Filter Filtering seemed so handy with variables that we thought it would be fun to have filtering as an independent action. All the contents of a filter block are passed through the named filter during output.PageTemplate - The Designer's Perspective

Who Are You? You are the esteemed Web Designer, aesthetically talented and perhaps artistically inclined. You know what makes a good Web page. You are not a programmer, though. It’s horrible when you have to go down to the caves where they keep the developers to explain where a simple login form belongs. You also don’t want to remember where their odd-looking programming code is supposed to go in your beautiful page.PageTemplate - The Programmer's Perspective

Getting Started Before you dig into the code, you might want to take a look at the designer’s perspective of PageTemplate. Using PageTemplate In Your Ruby Code This is a very quick overview, because I just spent hours going over the designer documents and I’m a little tired. First, of course, you’ll want to install the PageTemplate package. Once that’s done, require the package. require 'PageTemplate' You’ll need a PageTemplate object to hold values and parse template files.Jun 2, 2002 (Updated Nov 11, 2009)
The major directives require variables, which are just names for the value your want inserted, checked, or otherwise accessed. It’s a good idea to use variable names that make sense(name for a person’s name, title for the title of the page, etc.). Value Substitution Substitution is the easiest concept to master. When PageTemplate comes across a value directive, it replaces that directive with some text. Syntax [%var variable%] Example <h1>Hello, [%var name%]</h1> Every time that PageTemplate sees [%var name%] in your template, it will replace that directive with the text associated with name.Jun 2, 2002 (Updated Jul 11, 2009)
I’ll admit it. This list is very bad. Nevertheless, I keep telling myself it’s better than nothing.

I say that I do not have a favorite programming language. If I did have a favorite language, it might be Ruby. I’ve been messing around with it randomly for a few years, and I am continually amazed by how easy it is to build programs with it. Ruby is a delight to work with. I’m not sure how to describe it, because it uses elements from so many great languages. Freak that I am, I’ve gone out and started fiddling with some of the languages that Ruby borrows from so I can use Ruby better.

I already talk a little bit on this site about the language tools I use, such as Perl, Ruby, and Python. There’s a section where I touch on the most important tool of a geek like me: the text editor. But coolnamehere needs a section for the smaller tools that I use everyday. They may have been born on UNIX-like operating systems, but they do not live exclusively in that environment.May 29, 2002 (Updated Jul 11, 2009)

What can I say about Perl? I’ve had very little to talk about it on this site over the years, despite the fact that I use Perl on an almost daily basis. It’s not as cute as Ruby, or as clean as Python, but it’s always there. There have been numerous projects that are just plain easier in Perl. I can’t explain it.

I have decided to link to my LinkedIn profile instead of messing about with a resume page. That way I can show all the needed details, you can get some context, and I can keep from triggering any silly word filters with my site.

I occasionally have thoughts or comments that have no bearing on geekery or art. No direct bearing, anyhow. Actually, they could be about nearly anything. Or nothing. Insane rantings, if you will. Anyways, they get dumped in the Babblings (or Insane Rantings) section.Jul 11, 2001

Choose your weapon As a geek, your text editor is your most important tool. Pick one or two, and really get to know it. I don’t care if you choose Emacs, vi, SciTE, or whatever else. Pick it and learn how to use it. I want you to really get the hang of your editing environment. Being more skilled with your tools will make it easier for you to get work done.Jul 11, 2001 (Updated Jul 11, 2009)
Computers are all about programs. If you take the time to learn how to program, then you’re “on the inside” - more than just an ordinary user. The computer will obey your every whim, and you will be able to sneer at “lusers” (loser-users) who have no idea how their computer works. You will make millions of dollars working in your shorts. Beautiful people will throw themselves off of cliffs to be near you. The planet will be yours for the taking!

You may have already heard me say that I do not have a favorite programming language. That’s true. However, if you want to learn how to program - if you have never programmed before in your life (except maybe some QBASIC several years ago) - than Python sticks out way way ahead of the others. It is easy to get started, it is consistent across most operating systems, and you can make your programs as big, elaborate, and “real-world” as you want.Jan 17, 2001 (Updated Apr 9, 2017)

This is my original Python Babysteps tutorial, which has existed in more or less the same form since 2001. I’ve finally committed to writing a better version

Once upon a time I kept my stuff on a different Web site. This category is where I keep those pages. They may be updated at some point, or they might not.
