BASIC Back By Popular Request

Sales of Run BASIC have been pretty strong since we launched it on Jan 5. It's been really encouraging to see our users post about their experiences. People are building a lot of really neat things with it.

One thing that people seem interested in doing with Run BASIC is to use it as a frontend interface to various systems like home automation, machine control, monitoring and such. So requests for RS-232 serial port access, hardware port I/O and even USB devices are a hot topic. See this thread.

Hobbyists and people who take it upon themselves to automate their own work without the help of IT experts have traditionally used BASIC, and we intend to make Run BASIC work for them.

Run BASIC Podcast Interview - Part 2

As promised, part two of the Run BASIC interview with James Robertson is now online. Amongst other things, we chatted about how web development is harder than it needs to be, and about the challenges of marketing something different because people's perceptions can be hard to break through.

Java and BASIC - Simplicity and backwards compatibility?

Bruce Eckel and Joshua Bloch kick the can around about Java and complexity. Read about it here:

http://www.infoq.com/news/2008/01/java-evolution

I especially like this quote about Java and web development:

Web application development - this is difficult, and developing web applications with complex and underpowered technologies like JSP and JSF "is like eating soup with a fork"

I've been a Java programmer for 7 years. I've never liked the language. It always seemed to me to be much too verbose and controlling. It's amazing to me that it has been so popular, but that is more of a marketing accomplishment than anything else.

Run BASIC is a web programming system in development, and a really important part of what Scott McLaughlin and I are trying to do is to manage how the language grows. One important question to ask is how much emphasis to place on backwards compatibility as we more forward. Our goal is to create the best BASIC for the web, and it should still be simple and fun to use even as it becomes more powerful.

I invite your comments. :-)

Amazon's EC2 and Run BASIC?

I've been trying to figure out how to provide hosting for Run BASIC users. Someone had asked, so I suggested Amazon's EC2 system. I had read about it somewhere, and then it was recommended to me while I was being interviewed here.

The idea that I've been toying with is to charge a reasonable monthly fee like $15 for a Run BASIC user account on a VPS on EC2. A single instance of a VPS costs about $75 a month, and additional instances are created and removed as load changes.

So far things aren't looking really encouraging. Jerry Muelver has been looking into this matter, and so far it looks like a difficult matter to set up. Documentation is not easy to follow, and it just seems like a real hair puller. Check it out Jerry's story here.

Ajax and BASIC

Ajax (Asynchronous Javascript and XML) style techniques for building interactive web applications are the rage today. They are somewhat overhyped, but there is some value there.

Run BASIC already provides an exceptionally easy web programming system, but it does so with minimal special effects. There is a tiny bit of Javascript being used but almost everything is done with XHTML on the browser, and a very smart web application server.

In release v1.0 of Run BASIC the widgets (and indeed the page itself) are all objects. They are created by very simple statements. Any sort of Ajax inspired widgets for a future release of Run BASIC must not be any more complicated to use than the simple to use widgets that are already there.

Additionally, one of the most important aspects of Ajax is partial page reloading. This is important and we are eagerly planning to add this. What this will allow you the Run BASIC program to do is to reload a small part of your web app in the browser so that each user action does cause the whole page to be refreshed from the browser. This provides for smoother feeling user experience, and it also can improve performance.

So, Ajax must not complicate Run BASIC. Our design philosophy is to respect the simplicity of BASIC as much as possible. There are too many complicated programming systems out there, and the world doesn't need another one.

Moving Up From Web Design

Sometimes you will see people posting something like, "I've been creating web sites for years using HTML and FrontPage but I'd like to know how I can take the next step. How do I become a web developer?" Usually the answer provided is something like, "You should learn PHP."

Is PHP the answer? The answer is of course, it depends.

If you're just looking for a job skill you can put on your resume, then PHP may be exactly what the doctor ordered. But, if you are building your own sites or are doing custom work for a client, or want build something for use at the office, or if you just want to learn because programming interests you then you really should consider Run BASIC. You can get something going faster with Run BASIC than with more traditional web tools because Run BASIC is designed to be easy. It doesn't try to fit into the mainstream notion of a web tool. There are just too many of those.

Take a look at the site at http://www.runbasic.com/ for more information.

Intel and the OLPC

I was shocked this last week to discover that when Intel left the One Laptop Per Child project, many people immediately used this as an opportunity to say that OLPC is finished, done for, kaput. Why, just because one of their most recently joined partners was ousted? Their other partners include Quanta, Chi Mei, AMD, News Corp, Google, Brightstar, Red Hat, Nortell, Marvell, eBay, SES/Astra, Citigroup, Real Networks, Seagate, Adobe, and more.

Seriously, it seems like people want this project to fail and I'm not sure why. I am a proponent many of the ideas that are intrinsic to the XO laptop and the software it comes with, so I'm rooting for it to be a success. I even participated in their Give One Get One program, and I'm eager waiting for my very own green and white XO laptop.

Some people think that because Intel is also selling laptops to education ministries in poor countries that this dooms OLPC. I hope they're wrong. Intel is selling what amounts to power guzzling Windows laptops. They aren't rugged enough, they need AC power to run, and they run Windows and Microsoft Office. In other words they are only in the market to kill OLPC and they don't care the least little bit about benefitting children.

A lot of other people trash the OLPC because it isn't useful to them personally. This is just a nonsensical position to take. It isn't designed for the affluent consumer but for education starved kids in poor countries out in the bush. It fulfills it's intended role perfectly. It is designed specifically to open a world of learning to kids, and not just give them boring drill and repetition games. Why do American consumers tolerate boring educational software BTW?

The OLPC is a completely open platform with a designed-for-kids collaborative GUI and built in wireless mesh networking, special BitFrost security, and very radical learning software. It is uncompromising in executing the vision it sets forth. Very cool.

Some people criticize OLPC saying that kids don't need computers, but clean water and food. There are already many charities striving to provide those things. Why is it wrong for another charity to enrich their minds?

I encourage everyone to go to http://video.google.com/ and search for OLPC or Negroponte. There are some excellent long presentations that explain all the important ideas of OLPC.

Web 2.0 Podcast Interview - Run BASIC

James Robertson interviewed me yesterday on his weekly podcast Industry Misinterpretations about our new web appserver Run BASIC, where he describes it as a Web 2.0 platform. I don't usually use that term, but I guess if the shoe fits...

The interview lasted more than an hour, and it was a great time. We talked a lot about how complicated programming systems are these days, and how badly we need simplicity to make a comeback. :-)

Listen to part one of the interview here:

Part two will be posted next week.

iPhone BASIC?

Now that we've released Run BASIC, we would like to collect some feedback about the idea of adding some capability for the iPhone (and other mobile phones). There is a Javascript library and some CSS called iUi http://code.google.com/p/iui/ which provides the metaphor and visual look for iPhone (and iPod Touch) apps. This would make for very easy iPhone development, and it could be a great marketing button for Run BASIC.

Apple plans to announce some sort of SDK next month if I'm not mistaken, but a lot of iPhone software development will definitely still be web apps.

We could:

• Work on this now
• Work on this later
• Encourage the RB community to integrate iUi by writing BASIC code

Perhaps the last option is the most sensible for now. Feedback is welcome.

Learn Web Programming

What does it mean to learn web programming (or web development) anyways? Most of the time it means that you need to struggle learning a programming language, a web server, and a bunch of frameworks. When I tell people that they can learn web programming with Run BASIC their automatic response (unless they're complete newbies) is, why not learn one of the popular web programming systems? Why learn Run BASIC?

I'll tell you why. Because you don't need a thick book with Run BASIC. Because you don't need to install a whole bunch of stuff. Because you can create a program and put it on the Internet in the blink of an eye with Run BASIC. Because you can think about programming instead of about trying to satisfy all the requirements of Apache+Perl, or PHP, or Ruby, or whatever.

Not web programming

Okay, the title of this post is slightly wrong because Run BASIC is a web programming system. But, it isn't wrong because Run BASIC emphasizes not the webish-ness of programming, but the act of programming in BASIC.

BASIC always was the people's language. It was a success as the first popular way to create programs for home computers. It was so easy that even children learned programming with it. I was one of them.

So, this is the age of the Internet. Run BASIC is the BASIC of the age of the Internet.

Run BASIC's Programming Model

Most web app systems model applications as a collection of pages. Information must be persisted between pages in some sort of datastore. Sometimes this is in memory but oftentimes it is done in a database or by passing files. Run BASIC does not force you to partition your applications in this way. Instead you can write your entire application as a single continuous program just like you would write a desktop app. You create a new page in your application by clearing the page and placing new things onto it in a dynamic way.

Traditionalist procedural programmers can create entire applications using subroutines and functions, similar to how it is done in popular languages like QBasic. This democratizes web programming because many casual programmers are comfortable with this way of coding software.

More object-oriented thinkers can componentize their systems into objects and call methods on them. The objects can be purely data, or they can render into a display buffer and be injected into a web page. This makes it easy to have different parts of a web page managed in a modular way.

Run BASIC v1.0 is released!

Well I've been awfully quiet here for a couple of months, but for good reason. Everything we've been doing has been leading up to the release of our Run BASIC Personal Server, and now it's finally available. To pick up a copy head on over to http://www.runbasic.com !!

We've also launched a Run BASIC forum so come on over to http://runbasic.proboards82.com and see what's going on.

Perspective is Worth 80 IQ Points

Bill Williams sums up nicely why small is beautiful when it comes to programming tools.

Half Life 2 Episode 2

I've been a big fan of Half Life and its sequels for years, and Valve just released HL2 Episode 2 so I've looked at some reviews online. It's receiving very high marks by those who've played it.

So why am I posting about a video game here? Because I'm dying to play it, but I won't play because I can't allow myself to be distracted from working on Run BASIC right now. Probably I'll give myself permission to enjoy some game playing abandon when the holidays roll around.

In the meantime Run BASIC development is a lot of fun too in many important ways. :-)

Parsing XML in Run BASIC

One of the important feature that a Web 2.0 language needs is an XML parser. Run BASIC now has one built in. The XMLPARSER statement parses an XML string and returns an XML accessor object with a bunch of handy built-in methods for making your way through an XML document.
Here is a simple example of what that sort of code looks like:

a$ = "<program name=""myprog"" author=""Carl Gundel""/>"
xmlparser #parser, a$
print #parser key$()
for x = 1 to #parser attribCount()
key$ = #parser attribKey$(x)
print key$; ", ";
print #parser attribValue$(x)
next x

This short program produces:

program
name, myprog
author, Carl Gundel

And here is a short program which will display the tag names and contents of an artibrarily nested XML document:

xmlparser #doc, s$
print #doc key$()
call displayElements #doc
end

sub displayElements #xmlDoc
count = #xmlDoc elementCount()
for x = 1 to count
#elem = #xmlDoc #element(x)
print "Key: "; #elem key$();
value$ = #elem value$()
if value$ <> "" then
print " Value: "; value$
end if
print
call displayElements #elem
next x
end sub

Do-it-yourself programming

A friend of mine pointed me at this article "Do-It-Yourself Software" in the Wall Street Journal.

http://online.wsj.com/public/article/SB119023041951932741.html

Run BASIC and Liberty BASIC are both aimed at this market, and in fact this is the traditional niche of BASIC language products.

More on modularity

Run BASIC gives you the ability to create web pages that are component based. You define your own components and the ease at which you can plug these things together comes essentially for free. Here is a really simple example that I posted in our beta testing forum:

[masterPage]
cls
html "Program manager"
link #wiki, "Wiki", [runTheWiki]
print " ";
link #multi, "Multicounter", [runTheMulticounter]
print
if launchFlag then render #subProg
wait

[runTheWiki]
run "runWiki", #subProg
launchFlag = 1
goto [masterPage]

[runTheMulticounter]
run "multicounter", #subProg
launchFlag = 1
goto [masterPage]

Here is a version that doesn't use any GOTOs:

global launchFlag
call displayMasterPage
wait

sub displayMasterPage
cls
html "Program manager"
link #wiki, "Wiki", runSubprogram
#wiki setkey("runWiki")
print " ";
link #multi, "Multicounter", runSubprogram
#multi setkey("multicounter")
print
if launchFlag then render #subProg
end sub

sub runSubprogram linkKey$
run linkKey$, #subProg
launchFlag = 1
call displayMasterPage
end sub

So what does this do? It creates a simple web page with a title and two links. Click on the wiki link and the wiki program becomes part of the web page. Click on the multicounter link and the multicounter replaces the wiki part of the page. You can switch back and forth between the wiki and the multicounter at will with just the click of a mouse. What's even more interesting is that the multicounter is already a modular program, so you get three levels of modularity but you aren't limited to that.

So for programmers who like to put all their code in one file, there's nothing to prevent that. But people who like modules can have a field day.

Run BASIC enters beta testing

Well, it's been quiet here for a couple of months but now that the summer activities are over things have begun to pick up steam. In particular we started beta testing Run BASIC Personal Server a few weeks ago. We are still looking for a few more people to help test.

Run BASIC Personal Server is an all in one web app server, BASIC scripting language, database engine and more. It offers an extremely easy way to get into web application development. When I say extremely easy I am not exaggerating. We are talking "a child could do it" easy web programming.

When I asked my testers how they would describe Run BASIC, here is what some of them said:

" - - Run BASIC provides a complete alternative to the complex development languages that have evolved to script web content. Run BASIC wrests control back to you, allowing BASIC language scripting of web content. Create web pages in an easy to use project development environment and publish on the web at the click of a mouse."

" - - If you've ever used one of the classic BASIC interpreters, then you already know most of what you need to build dynamic websites using Run Basic."

" - - Run BASIC moves desktop programming out onto the internet. The screen displays, forms, interactions, graphics, and data-handling processes you create with clear, understandable BASIC programs suddenly become web applications, usable by anyone, on any platform -- Windows, Mac, Linux -- on any computer with browser access to the internet. With Run BASIC, you can write your program from anywhere, on any computer, and run it everywhere, on every computer."

If you are interested in Run BASIC and feel you have enough time to spend at least a few hours testing it out, please send an email to me at carlg@libertybasic.com and explain why you would like to be a beta tester.

We will accept only a certain number of applicants and I'll post a note here when we have enough.

Thanks!

Database and web capabilities

Our Run BASIC + SQLite integration is coming along nicely, and it lays the groundwork for using other databases later on (Oracle, SQL Server, MySql, etc.). One thing that we did to make using databases handy is that we built in some display technologies. You can query the database and then just use the RENDER statement to put the result on the web page. You can also inject some CSS styling right into that result, and you can even turn the line items of any column in the displayed table into links.

We also have added an httpget$() function so you can use HTTP to retrieve web documents like web pages, RSS feeds, etc. We plan to include an XML parser, and if we can come up with an easy to use way to stream through an HTML document we will provide that also.

These capabilities (except for the table rendering) will also be included in Liberty BASIC v5.0.
