Hi all, Just looking for a quick sanity check. I was thinking of writing a plugin for rails to give rails developers a good way of using the new firefox 1.5/safari canvas tags. I was thinking of grabbing an existing ruby graphics library and modifying it so that it renders via the canvas tag.. So you could have link_to_remote pointing to controller actions that instead of returning

I''ve written a JavaScript library called Ortho (http://www.craic.com/ ortho) on top of Prototype for creating ''diagram-style'' graphics in JavaScript. You can create histograms, graphs, timeline plots, ''maps'' of genomic data, annotated images, tree diagrams, etc. Unlike Canvas, it seamlessly integrates text with graphics and the output looks the same

Okay, I may have some questions about fxruby and probably the easiest way to ask them is by after I show a program. Plus I am eager to show how much fun I''ve been having... this is still not fully done to call it a v1.0 release, but it is already tons of fun. Please visit the download section of: http://rubyforge.org/projects/ifmapper/ There you will find the following: IFMapper by

Hi, I am quite new to R and I have two questions regarding ROCR. 1. I have tried to understand how to extract area-under-curve value by looking at the ROCR document and googling. Still I am not sure if I am doing the right thing. Here is my code, is "auc1" the auc value? " pred1 <- prediction(resp1,label1) perf1 <- performance(pred1,"tpr","fpr") plot(

Hello all, I've been working on a new R Graphics device that targets Adobe's Shockwave Flash format (SWF for short). It uses http://www.libming.org/ on the backend. Here are some example outputs so far: http://160.129.129.41/~hornerj/plots/ Once you click on the above, choose a directory like 'smooth' and then click on test.html to see a side-by-side comparison of the swf

How can I use the drawing canvas and its off-screen image buffer, say FXImage, to dynamically resize or have its width and height attributes changed in reply to user interaction with the main window (FXMainWindow)? It seems that whem I put initial values to W and H of the canvas or FXImage, they remain with its initial values no matter what I do whem resizing the main window. -- Ranieri Barros

I would like to use R.oo and tcltk to implement a Turtle World. I have encountered many problems because: 1) I am not sure how to implement static fields with R.oo 2) I am not sure how to implement a constructor that would call a function only for the first instance of a class (i.e., to initialize value of static fields only once) 3) I am not sure how to remove/delete cleanly existing

Looks like I have skipped on this, but still - a couple of questions: 1) Why there suddenly is an OrderedHash in ActiveSupport? (this glaring omission from ruby core is present in many apps already) 2) Why it doesn''t match the semantics of Hash respectively? 3) Why it''s #nodoc ? -- Julian ''Julik'' Tarkhanov please send all personal mail to me at julik.nl

Hello Campers! Is it just me or does Camping init the session twice on a redirect? If I have an app and when the user visits it for the first time, a session is generated. Afterwards I redirect the user in a service (that basically does auth) and he gets bounced to the login page - but when I arrive at the login page my SID somehow has changed :-( so there is a stale session dangling

If I were to serve files, would send_file via rails be slow? I think they will be 200mb avi files. Would it be better to send them via /public ? But I would like to track the clicks on each file - which makes me think that I can''t serve them out on /public as those clicks will not go through my application. Any help or suggestions? -- Posted via http://www.ruby-forum.com/.

I wonder - do we have some helper/processor/gem to automatically convert all URLs in a passed string to their canonical equivalent - i.e. with the protocol, host and such prepended based on the Rails environment. Super-duper infty for RSS feeds (I hate their requirement for canonical URLs everywhere). -- Julian ''Julik'' Tarkhanov please send all personal mail to me at

Hey, campineros. And many good handshakes to zimbatm for getting some patches applied. So, yeah, I''d really like to get rid of any serious dependancies with this 1.6 release. Anything that''s not in stdlib has to go. Of course, camping-omnibus will still assume the whole ActiveRecord, Markaby, Mongrel setup that''s in the history books. Metaid can be removed and

I have a <ul> that contains a number of list items, and I''m using the sortable_element helper to reorder then via drag-and-drop. This works great, however, when I insert a new <li> into the <ul> with Ajax, the sortable_element doesn''t know about it. Is there a way to refresh this collection? Thanks for any help. -- Posted via http://www.ruby-forum.com/.

I generate a lot of URL''s in my Facebook related code that point to our main site, not our FB app. My understanding was that the way to do this was to use ":canvas => false" as a parameter to url_for and link_to and so on. However, that doesn''t seem to generate the proper URL''s. The URL''s still point to apps.facebook.com (because they

Hi guys, I am new to this list and thought i''d say hello. I am using facebooker on a new project and so far I am really pleased with it. I saw that some users are having woes with the url_rewriter breaking urls for paths outside of the facebook canvas (i.e. your site supports both facebook and non-facebook users). I don''t have a prefect answer for this but I wrote a

Hi, I''m a newcomer to Ruby and to Rails, and am having a problem with character encoding. Now, I know ruby doesn''t handle unicode...but, characters like ? (eacute) and ? (ccedil) are part of the iso-8859-1 charset, so it shouldn''t be a problem, right? But, for some reason, the string functions still seem to hang on those characters. As an example, in a brand new rails

I found a reference to using attachment_fu and followed the lead of it but having an issue with the redirect_to that renders the fb:render tag - In my form I''m setting the canvas to false, file is being uploaded / save fine but when I attempt to redirect: redirect_to :action => :new, :canvas => true Unfortunatly it looks like my callback URL is getting printed twice, e.g.
