Cyrus in 2013
January 16, 2013 17:09

Well that worked out pretty well: I have a 3D environment on Android programmed in a simple but powerful declarative language which I've called "Cyrus".

Cyrus basically uses JSON all the way through: from user interface and scene graph to rewrite rules, on the wire and on disk. The Cyrus programming language is essentially JSON itself, as JSON rewrite rules. I've reduced the noise of JSON in Cyrus by taking out redundant double-quotes, square brackets and commas. It looks very nice to me.   ...

Empowering the World | NetMash

If you also think that hacking up 3D worlds on Android could be fun, then join me! Stuff you should expect to play with if you want to get involved includes Java, Android, OpenGL ES 2.0, 3D model creation, hyperlinked JSON and JSON rewrite rules. Creatives, evangelists and inspirers are also very welcome to get involved!

The idea is to make an app (NetMash) that lets people build, mash up, animate and program 3D worlds, shared online and all linked-up, Web-like.

Like creative-mode Minecraft, but adding easy in-world programming and shared online by default. Or maybe a bit like an open, distributed, generic, mobile Kodu (or here), for adults as well as children.

NetMash is intended to deliver creative empowerment to ordinary people. We professional software folk often get stereotyped as geeks, and the creative fun we often have dismissed as in some way unusual. That's a real shame, because such prejudice means that the other 99.9% of the world are simply missing out on the joy of experiencing the most creative and empowering activities humankind has yet invented.   ...

Fun and Virtual Worlds | NetMash
August 15, 2012 11:37

I just re-read my article on the Universe Web. I think it's pretty good. Indeed, to be honest, "programming as Cyberspace building" is where my heart has always been, and I'm all about following my heart this year. Especially if it's more fun, for both myself and others! Or if it opens up new worlds to new people.

In contrast, I don't see "fun" in W3C or IETF activities. Indeed, there's recently been a number of examples of tension in that world, between stabilisation and innovation, idealism and pragmatism, Enterprisey and Webby. Interestingly, all those examples have a "2.0" flavour: HTML5 (Web 2.0), HTTP 2.0 and OAuth 2.0.

My own interests are rough consensus and running code; innovation and pragmatism. Webbiness not in the W3C sense - "Web" Services, Semantic "Web", "Web" Sockets, etc. - but in the sense of "the simplest thing that works". Which is the Web of HTTP (1.1), URLs, JSON and REST, or specifically my FOREST interpretation.

I crave the simple and powerful, the cool and the fun. Which ultimately leads to the kind of thing I was describing as the Universe Web. And to be honest, I'd like to write and code for me, not for my peers and colleagues or for my career.

So, to the pursuit of pure joy in place of compromise, I'll now be focusing my energies on the journey of evolving the NetMash Java server and Android app towards an online, open, hyperlinked virtual world that is programmable in-world by users using simple rules.

Stay tuned!

OTS: The Benefits of both Native and Web Mobile
May 10, 2011 11:11

The Web, in its purest form - declarative HTML and CSS documents, XML feeds - is mashable, linkable, sharable. It's easy to create documents that slot into the global Web and can be accessed on any device; accessed by just a simple link. Servers can easily scale through statelessness and cacheing.

Native Mobile Apps are fast and slick. They are intimate with the dynamic, interactive, tactile mobile user interface, intimate with the capabilities of the device and intimate with the domain of mobile: photos, locations, contacts, messages.

OTS is a simple, clean, powerful approach to delivering Mobile functionality and content that is designed to realise these benefits of both Native Apps and the Web.   ...

Around the middle of February I completed a basic persistence and networking implementation for Fjord, then had to do other things for a month. Just recently I fixed Fjord to work with the latest version of the Node.js APIs.

Next project: I'm going to use Fjord in a Web Framework to be called "JSON-Mash".

I intend to show that JSON-Mash will be a great framework for rapidly building truly interoperable and truly scalable online and distributed functionality.

Here's how JSON-Mash will work.   ...

Fjord in Memory
January 26, 2010 13:46

Right, I'm pleased to say that I've now implemented enough of the Fjord language on Node.js to be able to run the Instrument example that I introduced it with. As yet, this runs in memory only - i.e., no disk, no network.

Here's the code on GitHub with tests that show how it works. The language has changed a little so I'll show the example here again, copied over from the test code, in order to explain the differences.   ...

Fjord in Node
January 6, 2010 17:03

Well, I've put together the first few lines of Fjord, implemented on Node.js.

Here's the description on GitHub: Fjord is a language for expressing domain logic as match-rewrite functions over mashable JSON Web objects.

I'm developing Fjord very openly, in the hope someone out there will be interested in getting involved in helping guide its design and implementation. I suppose code speaks louder than blog posts.   ...

Introducing Fjord
December 11, 2009 08:22

Following on from my recent article where I derived FOREST, this article offers the beginnings of a JSON unification and rewriting language that can be used in a FOREST architecture.

Why JSON, not XHTML, now? Well, I recently discovered that JSON is overtaking XHTML in interest, and I was further inspired by Kris Zyp's recent announcement of his JSON Schema Internet-Draft.

Fjord is a language for describing how the state of a JSON resource at any time depends on both its current state and on the state of other JSON resources that it links to via hyperlinks.

Fjord is a Norwegian word, probably pronounced 'fiyourd', and might stand for some combination of the words: 'Functional JSON Object/Observer Resource/Rule/Rewrite Dependencies/Declarations'. Or maybe it's just because they're truly awesome, an' I wanna go.

Fjord also gives me an opportunity to show some examples of the "end-user" view of a FOREST interaction; starting with a simple finance example.   ...
