Presenting TiddlyWiki to the W3C

leave a comment »

Today, my colleague Paul Downey has made an impressive contribution to Osmosoft’s mission to explain by preparing a paper about TiddlyWiki for submission to the W3C Workshop on Security for Access to Device APIs from the Web. It gives an overview of TiddlyWiki for technical audiences that already know and understand the mainstream web and its underlying technologies.

Paul’s paper can be found here:

I’m loving it in lots of different ways. It’s a really solid example of what I call a “manifesto-style TiddlyWiki”, a tightly knit mesh of content that together communicates a system of belief. I like his tone, too, nicely sober and authoritative.


The challenge that Paul has taken on isn’t to be under-estimated. I’ve had the chance to talk about TiddlyWiki to many different audiences around the world, but the most unexpected reaction I encounter is from people in that same, technical audience and it is, bizarrely, outright disbelief. Picking it up in the middle of a demo, the conversation goes something like this:

Jeremy at OpenTech

Jeremy: Here I am clicking the ‘save changes’ button, and now watch as I refresh the page in the browser, and you can see that the changes that I made have been persisted to disc

Expert: Right, that’s very interesting. What serverside technology are you using? I bet it’s Java, isn’t it?

Jeremy: No, actually, as I said at the beginning, TiddlyWiki is a standalone HTML file, with the application logic written in JavaScript

Expert: Ah, I see, so you’re using something like Rhino to run the JavaScript on the server?

Jeremy: No, not at all. TiddlyWiki runs entirely on the client browser, and takes advantage of special privileges accorded to HTML files loaded from “file://” URIs to be able to save itself directly to disc

Expert: That’s neat. So do you use Google Gears to handle going offline?

Jeremy: Sigh, no, not quite.

And so it goes, on and on. It sounds ridiculous, but it’s happened too many times or me to avoid thinking about it. It’s seems that the idea of a standalone HTML file is sufficiently far away from many people’s experience of the web for it to be invisible to them.

The frustration for me is because it feels as though TiddlyWiki has something important to say about the different things that happen if you let people hack the web without needing server infrastructure. My experience is that you can foster some intense innovation by radically lowering the barriers to the Copy/Modify/Share cycle that is at the heart of community innovation.

TabbedSinglePageMode for TiddlyWiki

with 6 comments

SinglePageMode” is a typically neat little TiddlyWiki plugin created by Eric Shulman. It restores the more conventional wiki behaviour of having a single page open at once, so that clicking on a link replaces the current page, rather than inserting it below, as TiddlyWiki usually does.

Eric’s plugin has been deservedly highly popular. It seems that for a significant proportion of situations/users, the default TiddlyWiki behaviour of having multiple tiddlers at once is just too complicated. Having a community plugin to ‘fix’ this is a great solution, allowing TiddlyWiki users to choose which behaviour they prefer.

But, from an interface perspective, one of the things I find troubling about the current implementation of SinglePageMode is that it rather takes away the whole point of TiddlyWiki: after all, it started out as an experiment in having multiple wiki pages at once, with a view to making it easier to refactor content between pages. It’s also frustrating to have to have two separate modes of operation, with slightly inconsistent behaviour.

I’ve given quite a lot of thought to how one might somehow unify these two modes, to give the clarity of single page mode without giving up on the ability to quickly flick between multiple open tiddlers. I just came across some sketches buried in an old virtual machine from 2006 that show one approach that still looks like it might be interesting.

When a single tiddler is displayed, it looks much like an ordinary TiddlyWiki screen:

with a single tiddler open

When a tiddler link is clicked on, the new tiddler opens in front of the previous one, building up breadcrumbs as a sort of rolodex of tabs:


Then the idea was that by riffling the mouse over the breadcrumbs you’d get a popup that allowed you flick back and refer to an earlier tiddler:


I’m not sure why I drew the popup at a reduced size, I’m not sure that that’s a good idea. I’d also intended to draw a frame showing a similar popup when hovering over any tiddler link.

I took some care to try to make it possible to implement this design with minimal changes to the TiddlyWiki internal Story object, it should be possible to do most of the work with CSS. I was imagining that there might be an ‘expand’ button over near the breadcrumbs that floops the various tiddlers out to their fully expanded size, looking like an ordinary TiddlyWiki.

Although I never implemented this design, I’ve not stopped thinking about these issues, and am exploring some of them in Project Cecily.

UPDATE: There’s some further discussion on the TiddlyWiki developers group.

Oxford Geek Night 22nd Oct 2008

leave a comment »

I’m looking forward to speaking at next week’s Oxford Geek Night at The Jericho Tavern. I’ll be talking about TiddlyStuff, including Project Cecily, for the first time showing it off on the new Firefox 3.1 beta.

Gosh, I just blogged.

What is the Point of Osmosoft?

with one comment

Osmosoft is the team of a dozen people that I lead within BT. It is the result of BT buying my tiny open source company in May last year. To the consternation of their corporate finance people, they did this despite there being no staff, no revenue, no sales, no customers in the conventional sense, and no “intellectual property” (the rights having already been made over to a non-profit organisation in Silicon Valley).

I was told that the rationale for the acquisition was something like this:

“We see innovation happening on the edges of open source communities, and we need to understand how it works”

It’s pretty refreshing that it talks about communities and innovation, and not, say, just something about lowering license fees. That statement was one of the reasons that I pursued the opportunity with BT. After a few conversations with my boss, I arrived at a basic set of four goals to sit under that rationale:

  • Drive adoption and improve the BT Web21C SDK by developing open source applications to exploit it
  • Build a world-class open source web development team, exploring how open source can make it easier to find and assess talent
  • Contribute to the innovation and adoption of the TiddlyWiki system, exploring the central question of how innovation occurs in communities 
  • Do all of these things transparently and publically, so that others in BT can follow us and learn from our mistakes

After a few months it became clear that we needed to improve our approach to the governance of open source usage and contributions within BT. I was given responsibility for it, and we added a fifth goal:

  • Evolve governance policies and procedures to remove the internal obstacles to working with open source, to maximise the benefit from doing so, and to protect BT from any attendant risks

In doing all of that, we adopted a few basic principles to guide us:

  • Show, rather than tell. The best way to learn about something is to experience it directly
  • Communicate with our colleagues across BT using the public internet to ensure the widest audience, and to allow collaboration with other organisations involved in similar endeavours
  • Put developers together in the same room to maximise the collaborative bandwidth
  • Treat TiddlyWiki as a microcosm of the kinds of open source projects BT might be interested in, particularly in terms of the innovation that can be seen in the TiddlyWiki community

In subsequent posts, I’ll talk about our progress against those five goals, and some of the work we’re doing to evolve decent metrics for the success of our work.

Decaffeinating the Tea in Hamburg

leave a comment »

The organisers have posted the video from the talk that I gave at the Next08 conference in Hamburg earlier this month. It doesn’t seem to be possible to link directly to the video; you’ll need to scroll down until you find “Jeremy Ruston”:

I was a bit more nervous than usual because I was standing in at short-ish notice for my boss. I added some laconicity, but the material is essentially his, as you can see in this video of JP giving the talk last December at LeWeb 3 in Paris. Osmosoft helped out with the slides, using RippleRap and TiddlyWiki to maintain my strict PowerPoint quarantine.

Happily at least one person liked it.

TiddlyWiki at OpenTech 2008

leave a comment »

Along with several of my Osmonaught colleagues, I will be attending OpenTech 2008 in London on Saturday July 5th 2008. It’s a very low cost event (£5 to get in!), and is focussed nicely on the hacker community. I went to the last one in 2005 and had a great time.

This time, I’m giving a talk entitled “TiddlyWiki Tales” which will be a round-up the latest TW developments, both from Osmosoft and the wider community. Later on in the day, my colleague Paul Downey is talking about “The Web as Agreement“.

We’re also holding a competition with a TiddlyWiki flavour and some interesting prizes:

The TiddlyWiki OpenTech competition gives you the chance to win a BUG (plus four modules)! The BUG base station and modules use open source software and snap together to create whatever device you want. There’s also a great second prize of a GP2X Linux powered handheld games console. A stack of O’Reilly books will be the third prize.

For your chance to win one of these great prizes, all you have to do is show us your TiddlyWiki skills. TiddlyWiki is written entirely in javascript, and has a great plugin architecture, so just like the BUG you can twist it to do whatever you want. It can pull in RSS feeds, and because it can be a local file (and you don’t have to worry about same domain policies), it’s great for mashups. There are already 400+ plugins you can use, but don’t let that stop you from writing your own new ones!

(See the Osmosoft site for full details).

Jermolene @ BlogTalk 2008

with 2 comments

So, I’ll be attending BlogTalk 2008 next week in Cork, along with most of the Osmosoft contingent. I’ll be running a brief demo of some of the latest TiddlyWiki wizardry, and we’ll have a little exhibition stand too. Being a webby sort of conference, we’re running a RippleRap server so that people can create and share notes about the conference sessions (regardless of the state of the wifi!).

I went to BlogTalk 2006 in Vienna as an independent hacker, and thoroughly enjoyed my first exposure to a crowd of people who are generally at the forefront of thinking about social software. Thomas and John do a tremendous job of bringing people together, and so I’m delighted that this time around BT are one of the sponsors of the event.
