Teaching an old dog new tricks

One reader commented, "So should a basic language add object-oriented features? For me, it would simplify things. Inheritance and polymorphism produces much less code, and FOR ME, much more simplicity. However, for a procedure-oriented person, only complexity has been added."

This is an excellent point. One way that I've tried to add objects to Run BASIC is to have some built right in. You don't have to create them and you don't need to import them, but you can start using them. This is hopefully one way to begin to help procedural programmers warm up to objects and there's no reason why the rest of the program cannot be written in a procedural style.

The other thing that Run BASIC does is take the RUN statement and adapt it so that other BASIC programs that you run can be optionally treated as objects, or if that's too far of a leap you can think of it as a modular library of code, like so:

run "mymodule.bas", #module
#module doMyWork("some string")

Flight Simulator in BASIC

I remember years ago that there was an instrument-only flight simulator written in BASIC and ported to different computers.  It wasn't much to look at because it was all character based.  Tom Nally has just released an open source flight simulator written in Liberty BASIC.  This one blows the doors off that old classic.  Check it out here.

BASIC for the web a killer app?

If you ask the average geek worth his salt what was the killer app that launched the microcomputer revolution the answer would probably be "Visicalc, of course!"

I take issue with this answer. Long before the spreadsheet application Visicalc was a gleam in Dan Bricklin's eye the most important and powerful application for small computers was the BASIC programming language. Without Microsoft BASIC (and this is Microsoft's real and lasting legacy if you ask me) very few people would have been able to do anything useful with computers. Most versions of BASIC back then were variations on Bill Gates' original BASIC interpreter.

Without BASIC we would not have seen so many kids grow up to be programmers, myself included. This is the very reason why I work on BASIC language products because I believe that there's no good reason why anyone with a little desire and time shouldn't be able to create software.

Run BASIC is very much in the same spirit as the early BASIC, but for the web. Now anyone can create web applications. :-)

Run BASIC - Killer app for the Internet age!

Run BASIC for Windows, Mac and Linux

Tonight I am pleased to mention that we posted Run BASIC v1.0.1 beta 3 for Windows, Mac OS X, and Linux (tested on Ubuntu). This is our first ever release of software for Linux, although people have been successfully using the Windows version using Wine.

It shouldn't take more than a couple of weeks to finalize v1.0.1 and release it. If you haven't had a look at Run BASIC check out the site. Make sure to watch the videos posted there to get a complete sense of just how easy web programming can be.

Eating my own dog food

Run BASIC comes with a bunch of example programs, one of which is a wiki called runWiki. It's about two pages long and is remarkable for what it does in those two pages, including the use of the SQLite database to store pages.

One of my customers (Neal) took that wiki and added a bunch of cool stuff to it like user accounts and many more formatting tags.

Now I've decided to take Neal's version of my original runWiki and use it to host a site for a civic group in the town of Ashland, Massachusetts where I live. It went live last weekend to coincide with the annual Ashland Day faire. Check it out at http://www.weloveashland.com

It's a pretty simple site which will get more sophisticated as we go. The beautiful thing is that it acts as a vehicle for producing runWiki3. I can customize it to my hearts content since I have all the source code in BASIC, the people's language. ;-)

Free version of Run BASIC

One thing that has been lacking in our effort to promote our Run BASIC web programming system is a free version. In fact there is no time limited trial either. This has been mostly because we have been unsure what would be the best way to do it.

What we've decided on is when Run BASIC v1.0.1 is released soon for Windows, Mac and Linux we will also release a free version. This free version will be for personal use instead of being a web application server. Users of the free Run BASIC will be able to create projects and use any features of the language, but they will not be able to serve applications. This will allow them to experiment and see if Run BASIC meets their needs. If it does and hosting the application is in the cards then an upgrade to the server version is available for $59.95, or hosting service can be purchased at http://www.runbasicnet.com

Comments and suggestions are most welcome.

Out of control!

On a Java project that I work on part time we use the Eclipse IDE, which is a power tool for Java programming. Java itself gets hard to deal with once your software gets to a certain size, and Eclipse tries to do a lot of the hard work for you. Java would be unusable without such tools.

On the flipside to this, we had been using an older version of Eclipse. Ultimately we decided to upgrade to a newer version (but not the latest) because we wanted to use Subversion instead of CVS for our source code control.

One of my colleages decided to attack the upgrade and document what was needed for everyone to use the new version. It seemed like it took him many days to figure it all out. The new version didn't look too much difference on the surface, but I kept hearing groans from him. Clearly something wasn't going well, so I went over and asked him what was the matter. His answer was simply, "I can't figure out how to do things that I used to know how to do!" The new software was getting bigger and more complicated.

There's a balance to strike when developing software. It's hard to make software easy to use while also adding new features.

Rewrite BASIC language today?

In the Usenet group alt.lang.basic there was a thread recently with the subject heading "Rewrite BASIC language today?" where the question was explored about how BASIC would be written in today's programming world.

Clearly there is a wide range of opinions in the responses. Some opted for being retro and simple. Some advocated adding commands for dealing with various things. It's good to have a discussion about these sorts of things, and this one went well. There are a lot of experienced BASIC programmers in that forum and it didn't turn into a flame war.

In my own response I wrote "BASIC needs to be simple. Adding C or Java features is a mistake for the most part. There is value in keeping things out of the language."

There needs to be a balance. Sometimes it makes good sense to add new things to a language. But as I just said... sometimes. ;-)

Commodore 64 Twenty-fifth Anniversary

Here is a YouTube video of a 90 minute presentation celebrating the 25th anniversary of the Commodore 64 home computer. The C64 was a groundbreaking machine and I know I'm not the only one who learned a lot from this wonderful machine and similar ones like the TRS-80, the Apple II, the Atari 800, and the TI-99/4. I programmed Commodore computers in BASIC, 6502 assembly language and Forth. Great stuff.

Go check this out for a fun romp into the past. The presentation touches on much more than just the C64. http://video.google.com/videoplay?docid=3754836267385299753

The Definitive Guide to SQLite, a PDF Download

Notice: I'm not sure anymore that this is a legally available file, so I've pulled the link until further notice. You can still purchase the book online at http://apress.com/book/view/1590596730

Here is a link to a PDF for the book The Definitive Guide to SQLite by Mike Owens. This looks like a great resource for Run BASIC programmers. :-) The download seems to take a while, so I wonder if their fileserver is swamped. I guess this is a very popular download.

[link removed]

Followup: For those who have been unable to download the entire file. It took me a few tries, and you may even try some other browser. Safari worked better for me than IE.

Net Neutrality

I'm not an especially political person, but Net Neutrality is an important idea that deserves all of our attention. Essentially since the Internet was recently deregulated, broadband providers are now allowed to prioritize and block traffic. Imagine if suddenly you were unable to Skype your best friend in another country, or if Google became inaccessible to you. What if the online community in a message forum you came to know and love was destroyed because access to it was now impractical to certain key members? What if an online business was suddenly destroyed because they no longer received the visitor traffic they once did?

Net Neutrality is a movement to protect free and unhindered access to Internet resources.

Ethan Poole wrote an excellent article about it here:

Think programming is too hard, or boring? Think again!

A couple of days ago I was at a Starbucks. I sat down around a large table to enjoy my coffee and a pastry. There were several other people there. I pulled out my iPhone to check my email. There was a fellow across from me with one of the new Macbook Air laptops, and a few minutes later a young man also sat down and pulled out a black Macbook. This concentration of Apple equipment made it easy for us to begin talking.

When it came to what sort of work we do, I shared about my business selling programming tools. I moved over to the fellow with the black Macbook and told him I wanted to show him my website so he could understand my business. When I showed him the Learn tab on the Run BASIC site and began to walk him through the examples the other people at the table came over to watch. As we went from simple "hello world!" to some easy graphics examples the reaction from onlookers was amazement! They clearly were not aware that programming could be so simple and cool. To them this was something way above them, and very dry.

What I took away from this is that people don't know that programming can be fun. They can do it, and years ago the average computer user did his own programming, in BASIC. Nowadays what gets promoted as programming is too hard, and it's no surprise that people don't want to do that. This is a misapplication of technology that makes things harder, and not easier.

We need to turn back the clock in this important area of programming.

iPhone SDK delayed?

It's beginning to look as though the iPhone SDK may not ship this month since Apple has been silent about it. It was supposed to ship by the end of February. Of course this doesn't really have any impact on Run BASIC since it will not use the SDK, but it will produce apps that run in the iPhone's Safari web browser.

We haven't talked much about our plans for iPhone support in Run BASIC. We should have more to say in the next month or so.

BASIC is bad because it's too easy?

A response to a recent post read, "BASIC is good, but I think it should be avoided as a first language because it pampers the programmer too much."

I won't be the first person to say that BASIC is perfect. There is no perfect language. However, to recommend that a first language should not "pamper" the beginning programmer seems to me misses the mark completely.

I'm guessing that this means that languages should force the beginner to be aware of low level details such as the type of numeric value (int, float, byte, etc.) or that the beginner should made to manage the allocation and deallocation of memory. What do these sorts of things have to do with the essense of programming? Since there are many languages which do not have these kinds of features, I can only submit that they aren't essential to programming. Therefore they are not necessary ideas to teach the beginner.

The nitty gritty details of how a computer works ARE important. These things should be taught to any serious student of computers, but they do not need to be the first thing taught. People who do not fancy themselves experts do not need to be bothered to learn them.

Easy is the quality that BASIC has, especially in the quickness of its learnability. This is almost to a fault I agree in the sense that a slightly more general and abstract language might be a little harder to warm up to but better in the long haul. However for the person who programs for fun, or who needs a light language for writing utilities or small personal applications, I think BASIC hits the mark pretty well.

Taking the Arc Challenge

Paul Graham, a very famous Lisp programmer who is well known for his continuations based web framework has invented a language called Arc (a version of Lisp). He came up with a challenge to see how others would implement a trivial web program in their favorite language.

Here's the Arc program:

(defop said req
(aform [w/link (pr "you said: " (arg _ "foo"))
(pr "click here")]
(input "foo")
(submit)))

Follow this link to see other submissions in different languages. Scroll down to to bottom to see the Run BASIC example. http://arclanguage.org/item?id=722

Now tell me which language you'd rather develop web apps in. BASIC is the one. ;-)

Web programming in... Java?

I mean, why? Of course that's how I feel about any kind of programming in Java. I recently found a blog where someone reviewed Wallace Wang's Beginning Programming book which teaches Liberty BASIC. The blogger seemed to enjoy Liberty BASIC and then went on to say that we was planning to learn Java. I wish that those presidential candidates would promise to reform our educational system by banning Java from k12 schools. People who are just learning programming need something that gives them a tighter feedback loop like BASIC does. If the learning experience isn't at least a little bit of fun it won't benefit the kids. Period.

People who trash BASIC haven't tried modern versions. Even the old DOS QBasic has everything the beginner needs.

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.

iPhone development - activation experience

Since we have decided to create some iPhone development features for Run BASIC I bought an iPhone for this purpose. I thought it would be interesting to post my personal iPhone experience.

So, I went to the Apple store. I said that I wanted to buy an iPhone, so the youthful Apple employee grabbed me a small black box from behind the counter and handed it to me. "Big day," he said with a certain air of importance. I thought that was a little over the top. I mean, it's a phone. I wasn't having a baby. My daughter put it well, "Maybe if he was going to give you the $400 phone for free it would have been a big day." Ah well. I suppose Apple store employees can be forgiven for drinking the corporate koolaid. ;-)

I told him that I was buying the iPhone because I am working on easy development tools for it. He didn't quite get it right away that I wasn't working on iPhone apps for people to consume, but a really easy way for anyone to create their own iPhone apps that run in the Safari browser. I explained more carefully and got a gratifying 'Ahhhh' response from him. Gotta work on that marketing message.

So I took the phone home and unpacked it. There's no manual at all. There really should be for that price.

Alright, I understand that you activate the iPhone using iTunes. I am a Mac user (and a PC user) so I thought I would activate the phone from my Mac. That didn't work. I needed a newer version of iTunes. No big deal. I downloaded and installed the latest. Still no good. Why? Because then I discovered that I needed OS X v10.4.x or better. What then dawned on me made me a bit angry. I was going to need to activate the phone using iTunes on Windows. I think that qualifies as mistreatment by Apple of its customers.

Okay, so now I upgraded to the latest version of iTunes on my Vista box. I plugged the phone in and activated it. It went smoothly from there.

I'll post more about the iPhone and our work to support it using Run BASIC in the days to come.

Debugging Run BASIC Web Apps

In Run BASIC's first release there is effectively no built-in debugger. Of course you can use print to log to the browser page or to a file, and this is no more or less than many other web scripting systems. We aim to do something about this in the very near future.

One of our users suggested that it would be good to create an inspector panel in Run BASIC itself and that we should add some reflection via an EVAL$() function that would allow arbitrary execution of BASIC code at runtime. We would probably also need to at least metaprogramming features like the ability to get information from the runtime like:

• The name of the current context (ie. function or subroutine)
• The names of all the variables and arrays in scope
• The source code for the current context
• A collection of objects that models the stack
• Probably more stuff

While this sort of thing is possible I think that we probably will initially provide a high level runtime inspection panel that the programmer can show and hide as needed. This is BASIC after all, and it should be as easy as possible to use. The metaprogramming stuff is cool though. ;-)

Web Programming for Fun

There has always been a culture of complexity-worship in the programming community. Some people seem to think that the Internet is a good excuse to take this even farther. This takes the fun out of programming, and it scares a lot of people away from even trying it. We think that this needs to be pushed back against. One of our goals in creating Run BASIC has been to make web development so easy that anyone can do it. As a language designed to make programming simple, BASIC is an ideal platform for realizing this idea.

We need a culture of simplicity. The computer should do that hard stuff for you. For example web application servers manage user sessions and processes, and these are things that require special administration by an expert in most web systems. With Run BASIC, except for a couple of fields in the Preferences tab that let you configure how long the timeouts are for sessions and processes, you don't really need to know anything about these. It's all done for you automatically.

Or for example let's say you want to draw graphics? There are no add-ons that you have to locate, download, and install with Run BASIC. It's all built right in, and just a few lines of code can draw some meaningful graphics into your web apps.

It's easy, and it's fun.
