New smalltalk website and Smalltalk activities in Barcelona
by Jordi Delgado 12 Feb '09

12 Feb '09

Hi, My name is Jordi Delgado and I am an associate professor at the Software Dept. of the Technical University of Catalonia (http://www.lsi.upc.edu/~jdelgado). I have translated to Catalan prof. Ducasse's book on the Botsinc system and I have been giving Botsinc and Smalltalk courses for almost a year now. The Smalltalk course is now a free elective course in our undergraduate Computer Science degree at the Barcelona School of Informatics. You can find information on our activities in the new smalltalk site: http://smalltalk.cat though the *entire site* is in catalan, not english. However, it is pretty easy to deduce what we are talking about. The main purpose of the smalltalk.cat site is to keep in touch with the local (small) smalltalk community. The site is quite simple, but good enough for the purpose it was designed for. It is powered by Pier 1.0 and Squeak. We have a quarterly course on Smalltalk based on SBE (http://smalltalk.cat/poos) at the Barcelona School of Informatics (http://www.fib.upc.edu), and also, for free, at a living lab called Citilab (http://citilab.eu). The Citilab course is open to everybody at no cost, only with the pre-requisite of some programming experience. And the course is identical to the one given in the university. Thus, here in Barcelona anyone can learn Smalltalk, it is free. The slides I use in my lectures are mainly translations of the open-source SBE course by Prof. Oscar Nierstrasz. I used Squeak to create them, mainly to impress the students (but with a result clearly inferior to what you get with Powerpoint, Keynote or Sophie). We also have a weekly seminar on Smalltalk with former students of the course (see http://smalltalk.cat/gts). BTW if any smalltalker comes to Barcelona and wants to get in touch with us, feel free to contact us. That's all, just to let you know we exist. Bests, Jordi PS: I am sending this to several smalltalk lists. Please, accept my apologies if you are receiving more than one copy of this message.

WAFileLibrary from external source
by Udo Schneider 12 Feb '09

12 Feb '09

All, How do I serve the content of WAFileLibraries from external sources? I exported the library contents using "Write To Disk". However changing the applications Resource Base Url only seem to affect resources embedded with #resourceUrl: . But I'd like to host things like SULibrary on external servers (S3) as well. Do I really have to have to link all the different scripts in #updateRoot: manually? Regards, Udo

Hi, it would be nice if in the page "New in Seaside 2.9" ( http://seaside.st/community/development/seaside29 ) you put a link to the script builder that some time ago you had talked about ( http://builder.seaside.st/ ). Just a though. Lautaro -- Luke LAut SkyFernadezWalker

JQuery updating DOM elements
by John Toohey 12 Feb '09

12 Feb '09

On a JQuery dialog, I would like to update the text input fields with default data, based on the data entered in the first field. I have the following code for the first field :- html span class: 'formdata'; with: [html textInput id: #tournamentname; value: tournamentEvent tournamentName; callback: [:value | tournamentEvent tournamentName: value. self test: value on: html]; onChange: (html jQuery ajax serializeThis)]. When a change occurs, I want the callback to call an update method, to update the remaining fields. Currently I have a small test method here. This is the code for the test method :- test: value on: html (html jQuery: #potsize) html: DateAndTime now #potsize is the id: of another field in the dialog. My callback works, but the DOM is not updated. What is the correct way to update other DOM elements in this fashion? Thanks. -- -JT

Google Maps API Services Geocoding ( resend for wrong format )
by Dario Trussardi 12 Feb '09

12 Feb '09

Hi All, i work with Squeak and Seaside 2.8. In my application i have integrate a Google StaticMap support from squeakSource GoogleStaticMaps. Now i'm interested, when the user create a new address, to define and save the relative geographic coordinates. In the Google documentation i read: *********************************************************************************** Geocoding is the process of converting addresses (like "1600 Amphitheatre Parkway, Mountain View, CA") into geographic coordinates (like latitude 37.423021 and longitude -122.083739), which you can use to place markers or position the map. The Google Maps API Geocoding Service provides a direct way to access a geocoder via an HTTP request. Note: the geocoding service may only be used in conjunction with displaying results on a Google map; geocoding results without displaying them on a map is prohibited. For complete details on allowed usage, consult the Maps API Terms of Service License Restrictions. Geocoding Requests You may access the Google Maps API Geocoding Service directly over HTTP. To access the geocoder, send a request to http://maps.google.com/maps/geo? with the following parameters in the URL: a.. q (required) - The address that you want to geocode. b.. key (required) - Your API key. c.. sensor (required) - Indicates whether or not the geocoding request comes from a device with a location sensor. This value must be either true or false. (Note that devices with sensors generally perform their own geocoding by definition; therefore, most geocoding requests to the Maps API Geocoding service should set sensor to false.) d.. output (required) - The format in which the output should be generated. The options are xml, kml, csv, or (default) json. (For more information, see Geocoding Responses below.) e.. oe (optional but strongly encouraged) - The output encoding format of the response. It is recommended that you set this output encoding explicitly to utf8 unless you have specific requirements to handle other encoding types. f.. ll (optional) - The {latitude,longitude} of the viewport center expressed as a comma-separated string (e.g. "ll=40.479581,-117.773438" ). This parameter only has meaning if the spn parameter is also passed to the geocoder. (For more information see Viewport Biasing below.) g.. spn (optional) - The "span" of the viewport expressed as a comma-separated string of {latitude,longitude} (e.g. "spn=11.1873,22.5" ). This parameter only has meaning if the ll parameter is also passed to the geocoder. (For more information see Viewport Biasing below.) h.. gl (optional) - The country code, specified as a ccTLD ("top-level domain") two-character value. (For more information see Country Code Biasing below.) Note: The gl and spn,ll viewport parameters will only influence, not fully restrict, results from the geocoder. In this example, we request the geographic coordinates of Google's headquarters: http://maps.google.com/maps/geo?q=1600+Amphitheatre+Parkway,+Mountain+View,… ********************************************** Now : after the user crate new address i can create a new WAUrl as above with specific address. My question is: how, i can, send from squeak this request to the internet for receive the answer? It's a good solution or i wrong? Any pointers would be greatly appreciated! Thanks! Dario

Google Maps API Services Geocoding

Hi Steve, about your e-mail: * I'm also interested in using the Google maps API from Seaside. I am far from * an expert but it's possible to use an HttpRequest object to do this from the * server. I solve it with: HTTPSocket httpGet: url * My question is why would you do it from the server when you could make the * request directly from the user's browser using the JavaScript API? My input from user's browser , based on Magritte, is a string. I'm not a javascript expert and i d'ont know how integrate it with seaside field. In the Google documentation i found this javascript but how integrate it with my input data ? <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:v="urn:schemas-microsoft-com:vml"> <head> <meta http-equiv="content-type" content="text/html; charset=UTF-8"/> <title>Google Maps API Example: Simple Geocoding</title> <script src="http://maps.google.com/maps?file=api&v=2.x&key=ABQIAAAAzr2EBOXUKnm_…" type="text/javascript"></script> <script type="text/javascript"> var map = null; var geocoder = null; function initialize() { if (GBrowserIsCompatible()) { map = new GMap2(document.getElementById("map_canvas")); map.setCenter(new GLatLng(37.4419, -122.1419), 13); geocoder = new GClientGeocoder(); } } function showAddress(address) { if (geocoder) { geocoder.getLatLng( address, function(point) { if (!point) { alert(address + " not found"); } else { map.setCenter(point, 13); var marker = new GMarker(point); map.addOverlay(marker); marker.openInfoWindowHtml(address); } } ); } } </script> </head> <body onload="initialize()" onunload="GUnload()"> <form action="#" onsubmit="showAddress(this.address.value); return false"> <p> <input type="text" size="60" name="address" value="1600 Amphitheatre Pky, Mountain View, CA" /> <input type="submit" value="Go!" /> </p> <div id="map_canvas" style="width: 500px; height: 300px"></div> </form> </body> </html> * I'm also wondering why you chose the static API instead of the dynamic one. * I haven't played with the static version and I'm curious about its * advantages. When i accept the user's browser i call the API for define the 'location' and after i browser a map for controll. Ciao, Dario

Hi Seasiders, Clearly an object of common interest: a seaside adapter for this: http://openid.net/ Do anyone have any progress on that? Cheers, Sebastian
