BASIC for the Raspberry Pi?

What's Raspberry Pi? It is a cool new single board computer about the size of a credit card. It runs Linux (it can run other things) and it only costs $35, or $25 if you don't care about networking. You only need a micro USB charger or batteries to power it, a keyboard and mouse, and an HDMI compatible monitor or TV set.

This new device is aimed at schools, but the appeal of such a device is obviously very broad. I went to their forum and mentioned the idea of producing a version of BASIC for the RP. The reactions were mixed. Seems like that crowd is strongly committed to Python. That's okay, I've got my hands full right now with Liberty BASIC and Run BASIC.

Perhaps in the future I will have a chance to do something. It would probably be my first open source project, based on Squeak Smalltalk.

Joy in Programming

I responded to a post on another blog (http://blogten.blogspot.com/2009/05/wards-comment.html) about how someone complained that the Smalltalk programming language permits the programmer too much freedom and that it's "too easy." The argument against being easy is that if it's too easy the programmer will be able to rush into creating software that is designed poorly. I have a hard time believing it is ever a benefit that something is hard to do. I think this applies to languages like BASIC so I'm copying what I posted there below.

Freedom is essential if you want to live life to the full, and not just in software development. We need to teach what is the best way to live in freedom, not impose a tyranny of suffocating "safety". If we don't build a culture of discipline and excellence then we deserve what we get. If we impose tons of rules to in an effort to prevent people from making mistakes we risk making software development such a burden that few people will want to do it anymore. It should be possible for software development to be an enjoyable activity, and for innovation and discovery to be experienced by newbies and experts. Joy is important in life.

Perhaps I oversimplify, but I hope this communicates an important idea effectively.

Knocked on the head with BASIC

A close friend of mine schooled in C++, Smalltalk, Java and Groovy told me the other day that he has written his first BASIC program by using Run BASIC. He had never written code in BASIC before, but he took my word for it that BASIC is a great language for throwing together solutions quickly. He said he was struck by the lightness of the BASIC language and that he enjoyed working in it. This is my paraphrase of what he said, because I don't remember his exact words.

I know there are a lot of modern BASIC implementations that force you to declare all your variables and give them types and sizes. Some of them keep the core keywords but add Pascal syntax, and some make BASIC look more like Java. I know there are some benefits to the way these other languages work, but BASIC is really meant to be very light and simple. In my humble opinion any language claiming to be BASIC which forces the programmer to dot too many i's and cross too many t's is not BASIC, but an imposter.

BASIC is a small language without too many rules.

Demo of Run BASIC at Smalltalk Solutions

Wednesday evening I had the priviledge of organizing the Seaside BOF (birds of a feather) session at Smalltalk Solutions. This meant that I was the one up at the microphone (which I pushed aside since the room wasn't big) for most of an hour and a half. It was fun and I didn't feel put on the spot since this was more of a round table than anything. I only had to try and direct the conversation some.

Here is James Robertson's blog entry with a photo of me presenting.

I'm very small in the frame, but yeah that's me all right. You can make out the Run BASIC web page up on the screen if you look carefully.

The demo was a little bit scary since I was modifying the Run BASIC code almost right up to the last second before the meeting. Scott and I were spending most of our free time at the conference working on some simple CSS integration. I'm hoping to put a screencast up to show how it all works.

Missing the Point

I read a paper the other day that described a system for teaching kids programming. It was one of those robot simulations where the student learns programming by using a special mini-language to teach an on-screen robot to accomplish certain goals.

So in this case the language in question is a simple one, specialized for the robot ideas as a gentle way to introduce programming.

Later in the same paper they described how a newer version of the system switched to Java as the language for the robot. I am amazed how easily people are brainwashed into using the popular thing in place of the right thing. Instead of something simple use the "industry standard" language, no matter how much it might damage their minds. :-/

What would be better? I guess the robot language they were using before would be just fine. Or pick some other simple language if you're looking for mindshare. BASIC, LOGO, Forth, Smalltalk.
