Timescope: to mobile and beyond
Ray Cromwell has the ability to do amazing things in the browser. We have often linked to his work on Chronoscope and more, and this time he has a screencast showing of Timescope “our charting engine, written in GWT, runnable as Servlet or Android native application, renders huge numbers of points at interactive rates, scriptable, annotatable like Google Maps, and stylable via CSS-like stylesheet mechanism.”
For those who know of Chronoscope, this is the commercial version, big changes include more accurate multiresolution filtering algorithm, Android native version, Chart Server, iPhone integration, synthetic datasets, a number of other things. We eventually hope to include a subset of complete implementation of R in GWT, to allow statistical work to be done totally in browser.
At the 7:20 mark, you can see GSS, which is an implementation of a CSS parsing and cascade engine in GWT, to support our totally custom set of properties, elements, and pseudo-classes.
Very cool indeed Ray.
What happen´s withe Ajaxian layout in Google Chrome???
Please adjust this!
Bye
It’s a missing double quote in an anchor tag. I’m sure it will be fixed soon.
Since when do we need to read Ajaxian with firebug to read all the content???
Hey, look at me! I’m over in the right column! Woo hoo!
I think this should be reposted to get a clearer vote ranking.
I this some sort of test? I sort of like the idea of a web development site forcing developers to use their tools to read it.
Yikes, a 1.6 rating! Either Ajaxians really don’t like GWT or canvas charting, or something is amiss.
@cromwellian – I think its because of the layout problem :) (which looks fine to me so it must be fixed)
.
As for me, I think its totally bad ass.
Should link to the showcase — Let’s you play around with the same thing he is showing in the video – http://timefire.com/showcase
@MichaelThompson – agreed. Replace the current, easy CAPTCHA with more difficult developer aimed puzzles, almost like a riddle.
>>Yikes, a 1.6 rating! Either Ajaxians really don’t like GWT or canvas charting, or something is amiss.
Well, considering this morning the story stopped in the middle of the second sentence, I’m not surprised.
Still very buggy and easy to lock up.
Pretty impressive Cromwellian :)
What’s easy to lockup? The showcase? Are you using IE? The showcase wasn’t supposed to be live yet. It’s a debug build that loads up vast amounts of JS, so it wouldn’t surprise me if you got a slow script warning. I have to recompile it for production, as well as make the sample datasets (some very large JSON files with 20k points) load on demand instead of load everything in the HEAD.
I’ll post a notice on my blog when the showcase goes live.
@cromwellian
You (probably) shouldn’t load the scripts in the HEAD of the document…
Check up the YSlow rules if you don’t believe me … ;)
