Spec project have a potential here and Spec over web frameworks to build fully desktop-capable web apps seems to be achievable. Spec over Amber (who will propose that?), Spec over Aida, Spec over Seaside? Benjamin, would you be a co-mentor of that project? Title: Spec over Aida for desktop-capable Web Apps Level: advanced Possible mentor: Janko Mivšek Possible second mentor: Benjamin? Description Spec as a means to describe and generate GUI has a potential to help building web applications as well. And because one of Spec goals is to become a platform/framework independent, this project has a goal to extend Aida component model for building Single Page web apps to become Spec-aware Technical Details Aida has a component model for building so called Single Page web UIs, capable of composing a hierarchy of so called web widgets, which are standalone reusable components, together with hierarchical web form support. Spec as descriptor and generator of UI is therefore a natural extension of Aida component model. When a HTML5 Web Components standard will be ready, Aida component model can be easily extended to support that standard as well, together with Spec (and maybe UIBuilder too?). Benefits to the Student Student will acquire the knowledge and experience of building desktop-capable UIs on the web using HTML5 approach. Benefits to the Community Spec has a potential to become a de-facto standard way of describing User Interfaces for Smalltalk projects from desktop to web and mobile, on a dialect and web framework neutral way. This project can contribute a piece toward that goal.

For now just express any idea you have here on the mailing list. Later we will together develop it to be in complete format together with two mentors needed. Deadline is end of Mart, so we have three weeks of time. To see how fully developed ideas look like please look at 2012 ones at: http://gsoc2012.esug.org/ideas. Note also that students yourselves can propose a GSoC project. So if you like to be a student on this year GSoC and have a nice idea, don't be shy and propose it here! The community will listen you and guide to the really nicely proposed project. Last year 6 student proposed projects were accepted and finished successfully! For the community, start looking around for students. Think about how to approach the universities near by you, do you know who to contact there, etc. We are namely preparing an application to this year Smalltalk Google Summer of Code under ESUG umbrella, as last year. If accepted, Google will pay few stipendiums to students on our Smalltalk projects. More on our special Smalltalk GSoC 2013 website: http://gsoc2013.esug.org I'm specially inviting mentors of all past GSoCs to rejoin the mentors mailing list, where we discuss all details about this year GSoC: http://groups.google.com/group/smalltalk-gsoc-mentors While students interested on GSoC please join a special Smalltalk GSoC mailing list for you: http://groups.google.com/group/smalltalk-gsoc-students Best regards Janko </pre> Janko Mivšek 2013-03-09T12:38:05 http://comments.gmane.org/gmane.comp.web.server.aida/3323 <pre>Dear Aiders, While watching an excellent presentation by Ilya Grigorik from Google Web Fast Team: Faster Websites, Crash Course on Frontent Performance part1: http://parleys.com/#st=5&amp;id=3648&amp;sl=0 part2: http://parleys.com/#st=5&amp;id=3649&amp;sl=1 I come to idea to implement few optimizations Ilya mentioned in his talk: 1. web page is now streamed to the browser to start sending as soon as possible so that browser can start fetching CSS and JS files listed in page header in parallel. Until now a whole page was first rendered before start sending. 2. gzip compression of page HTML and all other text resources like CSS and JavaScript. This reduces the load time substantially, usually about 5 times. End result is more than twice faster page load time, both time until page starts rendering on browser and overall load time. We are now below 250ms to the first byte time, which is nowadays a goal to regard your site as a fast one. Note that this includes a DNS lookup time (50-150ms), connection time (50-100ms) then content download. Another achievements are 4 A on http://www.webpagetest.org: A First Byte Time A Keep-alive Enabled A Compress Transfer A Compress Images F Cache static X Content Delivery Network detected This F cache static is such because we instruct browsers to cache images only 24 hours. For a reason to more easy upgrade web apps without needing instruct the users to reload pages. They just wait one day... X Content Delivery Network, well, I'm not sure we would profit much to use it except add another level of complexity ... Google regards such optimizations in this pageRank algorithm, which is one of the reasons to be worthwhile. All those optimizations will be part of next Aida (and Swazoo) release, it will also be soon on production server for http://www.aidaweb.si, so that you can try by yourself :) Best regards Janko </pre> Janko Mivšek 2013-02-05T17:20:58 http://comments.gmane.org/gmane.comp.web.server.aida/3317 <pre>Hi Folks, It's a pleasure inform that AidaWeb is available to use in Cuis Smalltalk in the repo: https://github.com/garduino/Cuis-Aida Thanks to the job of Janko to make the port to make it work in Cuis! You can install it on a Cuis image using the script of the README (be patient, the installation take time) or you can download a ready to use Cog image from the link provided in the same README. Enjoy! Coming Soon: A Morphic operator console for easier manage of Swazoo sites. Juan: You should update the ListOfPackages, as usual :) </pre> Germán Arduino 2013-01-29T15:01:29 http://comments.gmane.org/gmane.comp.web.server.aida/3303 <pre>Hi Janko: Just for comment that I found some things that I need to check in more detail (classes that are not inheriting correctly, missing extensions at class level) on the first filein of Aida in Cuis 4.1 (I did make a lot manually at method level, others at class level and seems that I lost things in the way) Then, I couldn't end today, as we talked on irc, to put a download image for you continue working in the port. As soon as I have news, I will comment here. </pre> Germán Arduino 2013-01-21T21:34:12 http://comments.gmane.org/gmane.comp.web.server.aida/3288 <pre>Hi: The first versions of Sport and Swazoo working in Cuis 4.1 with all tests green are ready to install.

To install Sport and Swazoo, follow the next steps: 1. Take a new Cuis 4.1 image. 2. From GitHub / garduino clone in your computer the repos Cuis-Cryptography Cuis-CompatibilityWithOtherSmalltalks Cuis-Pharo14CompatibilityLayer Cuis-Sport Cuis-Swazoo 3. In a workspace run the next script: | slash repo | slash _ FileDirectory slash. repo := '/Users/Shared/YOURCODEREPOSITORYPATH/'. { repo, slash, 'Cuis-Cryptography', slash, 'Cuis-System-Hashing.pck.st' . repo, slash, 'Cuis-CompatibilityWithOtherSmalltalks', slash, 'Cuis-CompatibilityWithOtherSmalltalks.pck.st' . repo, slash, 'Cuis-Pharo14CompatibilityLayer', slash, 'Cuis-Network-Protocols.pck.st' . repo, slash, 'Cuis-Pharo14CompatibilityLayer', slash, 'Cuis-Network-Url.pck.st' . repo, slash, 'Cuis-Sport', slash, 'Sport.pck.st' . repo, slash, 'Cuis-Swazoo', slash, 'Swazoo.pck.st' . } do: [ :fileName | CodePackageFile installPackageStream: (FileStream concreteStream readOnlyFileNamed: fileName) ]. 4. You will notice some warnings in the Transcript regarding some Network-* classes, it is because I'm installing here only the minimum code that I need for Swazoo and I must still end to polish the delta between the Network protocol in Cuis vs Pharo/Squeak 5. I did also an early port of TimeStamp, not existing in Cuis, and I have still 1 failing test. But Swazoo seems to work ok, all the test pass and the tests I did in the workspace seems to work, but as I'm not in expert in Swazoo, I will be more than happy of receive corrections, suggestion, etc, to leave the port in a stable state. -- Sincerely, Germán Arduino about.me/garduino </pre> Germán Arduino 2013-01-20T15:59:16 http://comments.gmane.org/gmane.comp.web.server.aida/3283 <pre>Hi Janko, Some while back I asked you about Magritte and whether/when some port or suitable alternative for Aida was in the works. You seemed to indicate that such a thing was in the works. Do you know if there has been any more progress on that? I remain keenly interested in that. - Bob </pre> Robert Calco 2013-01-16T20:35:13 http://comments.gmane.org/gmane.comp.web.server.aida/3279 <pre>Hi guys, Aida is now again loadable from SmalltalkHub, where you can find a project Aida under team Aida. To load it in Pharo, evaluate this script: Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfAida'; load. (Smalltalk at: #ConfigurationOfAida) load. As you see the ConfigurationOf is from SqueakSource but actual loading occurs from SmalltalkHub. Pharo 2.0 not yet tested! To load in Squeak evaluate this script: i := Installer monticello http: 'http://smalltalkhub.com'. iproject: 'mc/Sport/Sport/main'; install: 'Sport-2.031'. iproject: 'mc/Swazoo/Swazoo/main'; install: 'Swazoo-2.3beta3.1'. iproject: 'mc/Aida/Aida/main'; install: 'Aida6.5-interim.2'.

I've had a chance to play with it and would prefer to work in it with Aida over Pharo or Squeak. Simpler, smaller, more pleasurable all the way around. What are prerequisites that need to be added to Cuis to make it feasible to port Aida for real-world applications? Sport? Swazoo? Zinc? - Bob </pre> Robert Calco 2013-01-15T21:12:46 http://comments.gmane.org/gmane.comp.web.server.aida/3263 <pre>Every time I get the Aida one-click download for Pharo on Windows, I'm confronted with a problem that I believe is partly Aida's fault, and partly Pharo's. Periodically a DNR error shows up when the system tries to copy the running image (presumably for backup purposes).. The part that's Pharo's is a failure to properly initialize stdErr in ExternalWindowsOSProcess&gt;&gt;value before calling initialStdErr. Hence it's nil, and I get a DNR error when nextPutAll is invoked. The part that appears to be Aida's fault is the underlying command to copy the image that is being executed -- and failing, hence procInfo is nil, and so the fact that self initialStdErr is nil is exposed. My question is... what can I do to handle this? Obviously I need to change the ExternalWindowsOSProcess&gt;&gt;value method. How to do this without violating any underlying system semantics? Is it just a simple matter of reporting the failure as long as initialStdErr is not nil... or is there a change elsewhere that can fix the problem for real? </pre> Robert Calco 2013-01-06T19:55:03 http://comments.gmane.org/gmane.comp.web.server.aida/3262 <pre>Dear members of Aida/Web community, Let this year be a year when all your best wishes comes to true!

Some questions I've: 1. I'm porting Sport-2.031.mcz, is the correct version to port? 2. Sport don't have tests? 3. I'm porting Swazoo-2.2.mcz, but I saw that exist also a Swazoo-2.3Beta2.6.mcz. Which is the correct to make the port? Ok, it's all for now, I'm copying also the Cuis list just in case of interest.

Dirk </pre> Dirk Verleysen 2012-12-16T13:09:45 http://comments.gmane.org/gmane.comp.web.server.aida/3243 <pre>Dear all, Next spring will be 30 years of Smalltalk-80 and even more years of MVC [1][2] as currently the hottest pattern specially in JavaScript world. Just look at all those client-side JS web frameworks like Backbone, Ember, Angular, Knockout...[3]. A perfect time therefore to upgrade Aida's MVC to the current bleeding edge. Well, if we Smalltalkers were on MVC first, we need to catch JS guys and be first again :) So, my two-step plan is as follows: -- 1st step: Introduce a dependency mechanism as known from first MVC implementations from 80s on VisualWorks [1]. Dependency mechanism in a sense that all views dependent of some value update automatically after this value change. Currently we need to update them manually, with statements like: field onChangePostAndUpdate: someElement -- 2nd step: Move dependency mechanism to client-side so that all updates of dependent views will be done locally, without server needed. Only value change will be sent to the server. This will speed up web apps substantially, specially the mobile ones. After achieving the second step we are on a path to even more standalone client-side web apps. Aida will generate them on the server and send to the client, then 'disconnect'. Apps will therefore run autonomously and connect back to the server just from time to time to synch data changes. Here (if not for 2nd step already) Amber is what we can count on. So, that's my current brainstorming, with 1st step quite advanced in the head already, it could be that it will be ready for implementation soon.

Aida is namely not just a web framework but complete application server. Here is the article: http://panyasan.wordpress.com/2012/12/10/why-we-need-a-nodejs-application-server-or-writing-boilerplate-considered-harmful/ As you see Aida has most features from his proposal, except persistence and cloud support. Here are most interesting parts of his article: ... There is, however, one big issue that holds me back from starting to work on any of those ideas: the lack of the right end-to-end stack including a decent application server for NodeJS, which will free me from having to worry about boilerplate code for things like authentication, user management, access control, etc. ... I shouldn’t spend my time worrying about how to store passwords securely, or how to synchronize data between the client and the server, or how exactly model data is persisted in what database. ... I think such a platform would not only save thousands (or more) of hours of developers’ time. This time could then be invested instead in solving the application-specific problems in thorough and creative ways. ... There is a wealth of JavaScript frameworks on the client and on the server side, but, as far as I can see, no such thing as an “application server” known from the Java world yet exists. ... I see a number of features and characteristics of such an application server: - It should not assume any particular rendering model on the client (DOM-templating vs. widget objects) - It should also not force a different programming model on developers (like Opa or Meteor), but let you code in plain old asynchronous javascript... - It should have an integrated API for client and server. - It should provide a static HTTP server, REST routing, and bidirectional, realtime messaging and broadcasting (such as Socket.io). - It should offer async startup/plugin/configuration system like Cloud9′s Architect. - It should provide an out-of-the box system and API for user &amp; group management, registration, access control, Password storage/retrieval /update etc, preferrably with a set of built-in templates that can be used for managing the most generic configuration tasks. With this, a pluggable system to use third-party authentication providers. - It should also provide an integrated system of data modeling and persistence. I really do not care about database technology. I simply want to store, edit and retrieve my model data. - It could also have a toolset that would allow you to deploy your application instantly to a cloud provider such as Heroku or Nodejitsu </pre> Janko Mivšek 2012-12-16T12:01:15 http://comments.gmane.org/gmane.comp.web.server.aida/3239 <pre>Hi Guys: I'm currently working almost only in Cuis and porting packages that we need there.
