[ANN] Swazoo has now WebSocket support
by Janko Mivšek 12 Dec '10

12 Dec '10

Dear Smalltalkers, Past few days I worked on WebSocket implementation in Swazoo Smalltalk web server [1], in coordination with Philippe Marschall from Seaside [4] and Nicolas Petton from Iliad [5] devteams, so together with me from Aida/Web [3] our cooperation ensures that this implementation is ready to be adapted for all three main web frameworks. Why WebSocket? Because it will replace current Comet hacks to enable a bidirectional messaging between browser and web application, specially for web app to send something back to the browser without waiting for user to click something. Read a bit more about WebSocket here: http://dev.opera.com/articles/view/introducing-web-sockets/ WebSocket as browser supported technology enables opening an always present channel, so that web app can send commands like update some element of the webpage at any time. That's why WebSocket is ideal for so called "real-time" web. You are invited to look at the code for Squeak/Pharo as Swazoo2.3beta1.1 at http://www.squeaksource.org/Swazoo.html A bit more about WebSocket in Swazoo: http://www.swazoo.org/websocket Best regards Janko Swazoo maintainer [1] Swazoo WebSocket support http://www.swazoo.org/websocket [2] Introducing WebSockets http://dev.opera.com/articles/view/introducing-web-sockets/ [3] Aida/Web http://www.aidaweb.si [4] Seaside http://www.seaside.st [5] Iliad http://www.iliadproject.org

Re: [Seaside] Seaside Hosting bug ?? (was: Pier on SeasideHosting problem)
by laurent laffont 11 Dec '10

11 Dec '10

Thanks Yanni. But still doesn't work but it seems not an image problem. If I put the fresh pier2 image on an old (6 months) Seaside Hosting account (seaslides.seasidehosting.st), it works. If I put it on the newly created account, "Bad Gateway" Error. If I take my working Seaslides image of seaslides.seasidehosting.st and put it on pharoconf-annecy.seasidehosting.st, "Bad Gateway" error again. So it seems too me that the images are correct. But for a reason I don't know, I cannot set it up on a newly account. (I've created again another account to check). Cheers, Laurent Laffont.

[OT] XULJet Framework
by Pavel Krivanek 09 Dec '10

09 Dec '10

Hi, I would like to mention the XULJet Framework [1] here. It is a JavaScript framework for development of desktop applications on Mozilla XULRunner run-time. It uses component model and XUL/HTML/SVG canvas similar to Seaside. Of course it is not Smalltalk and because of JavaScript limitations the similarity to Seaside is only approximate. However mainly together with CouchDB it may be interesting alternative platform for some applications. It was started as side-product of SeasideXUL development. Cheers, -- Pavel [1] http://code.google.com/p/xuljet/

HyperGraph, Topic Map, Mind Map
by Hannes Hirzel 08 Dec '10

08 Dec '10

Hello Is there something like the HyperGraph implementation for Java (http://hypergraph.sourceforge.net/) for Seaside (I assume SVG/JavaScript based). I vaguely remember having seen an announcement some months ago but I cannot find it anymore. I'd like to use it for navigating in mind maps and/or topic maps. Regards Hannes

error uploading file
by Esteban Lorenzano 08 Dec '10

08 Dec '10

Hi, I'm again with the basicNew: primitive failed when trying to upload a file... I tried to avoid the problem by using swazoo server, but that was not an option :( This is the problem: I need to upload files (using "streamUploads" option of comanche adaptor), and that works fine in development, but not in production. When running in production, I'm getting a primitive failed when trying to store a byte string, because it is receiving a -19 as a requested storage size. I'm attaching a log with the debugger information I could get. Also, this is the system information: CPU Intel(R) Xeon(R) CPU X3360 @ 2.83GHz SO Linux, I can't say which version... looks like a suse, but I dunno. Pharo 1.1.1 (core) Seaside Loaded with ConfigurationOfSeaside30 version 3.0.2 VM Tried both: exuperi 0.15 and latest cogvm for unix Thanks, Esteban

error detected on WATemporaryFile
by Esteban Lorenzano 06 Dec '10

06 Dec '10

Hi, I'm using upload streaming and I detected a bug on the solution: WAFile class>>fromChunk: aChunk does simply: ^ self new readFromChunk: aChunk; yourself but WATemporaryFile>> readFromChunk: (who must derive the chunk into a temporary file), does not exists. Instead, it exist: WATemporaryFile >>initializeFromChunk: aChunk (which is never been called) I tried renaming #initializeFromChunk: to #readFromChunk: (and removing #initialize send), and now seems to work. Cheers, Esteban

i am on the last leg of my journey in getting a podcast set up on my pier site, and i have one more question that is more seaside than pier.. in order for itunes to index and use your feed, it has to have direct access to the real file url of your podcast episode. my rss feed currently sends this: <enclosure url="/?_s=K08URB5OyCLsVbHr" length="8740698" type="audio/mp3"> what i need is something like this: <enclosure url="http://www.thoseoptimizeguys.com/f4/7j0yahammck0qpjwxifiuc8mdeuo6k/Those-Op…" length="8740698" type="audio/mp3"></enclosure> how can i get WAUrl to spit this out? ideas? thanks! -- ---- peace, sergio photographer, journalist, visionary http://www.CodingForHire.com http://www.coffee-black.com http://www.painlessfrugality.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101
