Works fine on Nexus with Chrome Beta. :-) Perfect Cloud app and faaaast!!!! :-) OpenGL 2D canvas hardware support! Guido Stepken

Nevertheless, IMHO the development also exposed several sustainable advantages. As Hannes mentioned, the browser became a universal client for any applications, reducing the need to adapt applications for different operating system or other basic technologies. As far as I understand for instance Googles vision, it should even become the runtime environment of the user interface of the operating system. Besides, and this is especially true for mobile devices, using a client-server architecture the computation power and data storage shifts more and more to the server/cloud instead of the desktop. This is a large advantage for developers and system engineers for maintenance and operation especially when deploying a new version of a software as there is no software installed on the client directly. Cheers, Chris

On my Nexus the Google Chrome browser *is* a WebGL app itself. Thereunder the V8 Javascript interpreter, which internally creates metaclasses e.t.c. The two core developers were Smalltalkers! :-) What can we expect from Google Chrome? Separation of Browser and JavaScript interpreter, the interpreter then resides on the server, sending OpenGL directly via websockets into the dumb OpenGL terminal. And Google Chrome interpreter also has some (new) programming languages under the hood, Smalltalk included. C++ interpreter already works. Have fun, Guido Stepken Attatched screenshots from Samsung Nexus.

I tried several new concepts to develop on tablet (Bluetooth keyboard, mouse) during travels: Jens Moenig's ELEMENTS: http://www.chirp.scratchr.org/blog/?p=24 Fun seeing Smalltalk code in colored blocks, pushing them around like in EToys, generating/refactoring code. Much better designed, because of LISP + OpenGL is: http://blocky.io See the videos. Blocky makes no difference between Morphs and Code. This is pure fun, developing programs, games on tablet, and its incredibly fast! Have fun!

Compare to Android 4.0: Android has joined the 2.3 line for mobiles with tablet line and has invested much much brainpower in finding out, how apps can be designed, that they can comfortably be used on different resolutions, portrait as well as landscape.

Out of my perspective it would be far more important to move in the direction of web-based technologies also in this area. Looking at the success stories of Pharo and our own strategy I do not see the advantages of having multi-touch support for the development of such applications. >>> >>> Or did I misinterpret your intention? >>> >>> Cheers, >>> >>> Chris >>> > > > > -- > Milan Mimica > http://sparklet.sf.net

Ideally I would like to write Smalltalk > code transated to the host language plateform. It would be worth giving it a try with a simple exercise... with Amber Smalltalk http://amber-lang.net/ and Morphic.js http://astares.blogspot.com/2011/03/morphic-in-javascript.html What is implemented so far http://chirp.scratchr.org/dl/experimental/JsMorphic/morphic.txt No idea if that offers enough for Dr. Geo.... > Whatever, html5 are really desktop application downloaded at runtime. Yes there is now the option of 'one web page applications'. This is done when going for an Amber solution actually. There is some discussion on Morphic on the Amber Smalltalk Google group; in short - you may add any JavaScript library to Amber. - you may call any JavaScript code just by entering it between < > (JavaScript code as 'primitive calls') - there are simple mapping rules so that you can call an existing JavaScript API with Smalltalk expressions. The new HTML5 <canvas> tag seems to offer a lot of possibilities. http://www.canvasdemos.com/ No idea however how it compares in terms of performance with a direct solution in Pharo. > are still moving in circle since 40 years. In which sense do you mean this? The web browser is actually an universal client these days. Please note that Amber is still quite early in development --- version 0.9.1 And you have to shift gears mentally to get used to the file based approach (github). But actually it still feels like Smalltalk. For doing some experiments and proof of concept Amber is good enough. In case something does not work in Amber you can just do it in JavaScript. Smalltalk is no longer a closed world but running on top of a JavaScript engine where many external libraries are available. I think this is a very interesting development. --Hannes > > -- > Dr. Geo -- http://www.drgeo.eu > > >

But, to not shock the devs on this list, Pharo may offer much more than just an IDE with a headless operation on the server. Innovation on the server part is as important as using modern web-technologies for the user interface. Cheers, Chris
