Symposium

We have started collective.amberjack presence in Sorrento with Massimo's presentation at the European Plone Symposium. 

Sprint

Then we had two sprinting days. We have started day one with brainstorming. We had three objectives/questions:

• collective.amberjack sandbox
• refactoring the code - how to simplify collective.amberjack tour definition and registration
• translations - how to manage tour/steps translations

thanks to a fruitful discussion (garbas, dukebody, gborelli, miziodel, shywolf9982, sorry if I forgot your name ;-) we have right now answers to all of our dilemmas.

SanDbox

First idea of having a sandbox for collective.amberjack came up at last Plone Conference in Budapest. We have collected a lot of ideas for different use cases. We have had also some internal brainstorms in RedTurtle about it. Finally after confronting all the concepts - during Sorrento brainstorming - we will have a simple solution which should satisfy most of the users:

Code refactoring

We have started refactoring collective.amberjack. There are 3 areas of interests: javascript, tour definition and tour registration. Luca was doing a great job trying to simplify javascript part. He also prepare a good startup for future enhancements. I was refactoring tour part. We have decided to use a 

configuration baseD tour definition,

which looks like that:

[amberjack]
steps = 
        0_create-a-new-folder
        1_fill-out-the-fields
        2_publish-the-folder
        3_all-done
title = Add and publish a Folder

[0_create-a-new-folder]
blueprint = collective.amberjack.blueprints.step
title = Create a new folder
url = /
text = Folders are one of ....
validators = 
        python: isManager
        python: isNotFolderCreated
microsteps = 
        0_0_microstep
        0_1_microstep
        0_2_microstep

[0_0_microstep]
blueprint = collective.amberjack.blueprints.microstep
description = If you don't want to perform the ...
automatically done by your browser.

[0_1_microstep]
blueprint = collective.amberjack.blueprints.microstep
idstep = menu_add-new
description = Click the [Add new...] drop-down menu.

[0_2_microstep]
blueprint = collective.amberjack.blueprints.microstep
idstep = new_folder
description = Select [Folder] from the menu.

This concept is well known across the community. I hope it will be also more human readable comparing to python dictionary ;-). We have a working version in the trunk. For new tours we have also 

new tour registration 

- comparing to old approach (registration only using ZCML) you can now use also TTW registration. Other important change is that tour doesn't need to be a python package any more. Because it's a simple .cfg file right now you can simply zip it into an archive (zip, tar) and register it. We have a working implementation for web source and local file system registration (which you can find in the trunk). Archive file can be shipped with multiple tours and with

translationS

which right now are still just a concept that need to be implemented. We would like to make a use of i18ndude tool but because it was designed for ZPT this could be a wrong approach. Overall idea is to keep all the files (tour and the translations) together, something like:

- mytours.zip
  |- tour1.cfg
  |- tour1_en.po
  |- tour1_it.po
  |- tour1.pot
  |- tour2.cfg
  |- tour2_en.po
  ...

Fixing bugs

Mirco and Federica were working together and did an enormous job fixing most of the 1.1a release bugs. Thanks to Rob we have solved also some TinyMCE problems that we have had. We have still some open issues, like 'new portlet creation' tour that need some attention so we still need your help!

What's next?

The current development focus is on 1.1 release, which includes:

• new tour definition (python dictionary based tour will still work until 1.2)
• new tour registration (old registration will still work until 1.2)
• finish translation implementation
• fix last bugs
• deploy sandbox probably on demo.plone.org
• collective.amberjack.windmill - which should become default interface for creating and editing tours; we have right now something more then just proof of concept:

Here @RedTurtle we are heavily using funkload for acceptance and benchmarking tests. We have started using it in 2008 just after Bristol Performance Sprint. We have found even more useful with buildout recipe. The only missing part was the recorder. It's built-in Funkload itself, but it was not enabled in the recipe. Well - now it is ;-)

/ If you want to know how to include funkload in buildout project - check my previous blog /

Starting a recorder is quite easy:

$ ./bin/funkload record -p 8080 MyTest

for full usage call:

$ ./bin/funkload record --help

This will start proxy on 8080 port and save all your browser requests to MyTest funkload scenario. Now open your browser, change proxy configuration to localhost:8080 and click-through test case. When you finish - stop the proxy with Ctrl-C. Funkload will generate a test_MyTest.py file and notify you where you can find it. It should be now collective.funkload compatible - you can lunch:

$ ./bin/funkload test /path/to/test_MyTest.py

To test it.

Another small improvement is a PloneFLTestCase. It extends default funkload test case, implementing two additional methods helping with Plone content creation. Right now instead of using this approach:

folder_portal_factory = self._browse(server_url + "/coreloadtests/Members/" + self.user_id +"/createObject?type_name=Folder",
                                             method='get', 
                                             follow_redirect=False,
                                             description = 'Get folder portal factory')

folder_edit_url = folder_portal_factory.headers.get('Location')        
folder_id = folder_edit_url.split('/')[-2]

folder_created = self.post(folder_edit_url, params=[
    ['id', folder_id],
    ['title', 'folder'],
    ['description', ''],
    ['description_text_format', 'text/plain'],
    ['subject_existing_keywords:default:list', ''],
    ['last_referer', 'http://localhost:8080/coreloadtests/Members/' + self.user_id + '/view'],
    ['form_submit', 'Save']],
    description="Post /coreloadtests/Members/user...280843853/atct_edit")

new_folder_id = folder_created.url.split('/')[-2]

you can just do:

new_folder_id = self.addContent(
        server_url, 
        portal_type='Folder', 
        params=[['id', 'id'],
                ['title', 'testing title'],
                ['description', 'testing description'],
                ['description_text_format', 'text/plain'],
                ['form.submitted', '1'],
                ['last_referer', ''],
                ['form_submit', 'Save']], 
        description='Create folder')

It doesn't do much, but for sure it helps you keep you test case readable.

Ogni tanto ti ritrovi con qualcuno che ti racconta le ultime meraviglie della realtà aumentata [wikipedia]. 

Fondamentalmente (e semplificando moltissimo la cosa..) si tratta di sovrapporre livelli informativi alla realtà che stiamo vivendo.

Lo possono fare sfruttando in vari modi oggettini che sono già presenti: dal famoso caschetto da realtà virtuale all'ormai famigerato iPhone.

Sicuramente l'uso di device mobili è l'opzione più attraente e più consumer.

I signori di wikitude si sono inventati:

• una community dove ognuno può aggiungere i suoi punti di interesse (POI): wikitude.me
• un browser che gira su Android, iPhone, e Symbian (Nokia N97 e N97 mini). iPhone 3GS. Il mio ovviamente non va :(
  
• volevamo farci mancare delle API? ovviamente no! Certo che in Java...

l'effetto finale è notevole:

Packt Publishing, uno dei leader nell'editoria relativa al software libero, organizza ogni anno il premio "Best open source CMS".

A partire dallo scorso Giugno, dopo che un panel di esperti ha selezionato i "top five" della categoria "Other open source CMS", i voti del pubblico sono affluiti fino alla fine di Ottobre, decretando il successo di Plone, come già nel 2008.

Per noi che conosciamo Plone e ci lavoriamo quotidianamente, questo risultato non è certo una sorpresa: per chi non lo conosce ancora, può essere un importante elemento di valutazione.

C'è da dire che, di anno in anno, gli organismi di terza parte che valutano i CMS con griglie molto severe, come il CMS watch, collocano regolarmente Plone ai livelli più alti come prestazioni complessive. E' importante diffondere il concetto che Plone è davvero un sistema completo e di classe enterprise, e interessa a tutti (a noi come ai Clienti) che riconoscimenti come questi stiano a dimostrarlo.

I have been delegated as a RedTurtle member to join RuPy conference that has been held in Poznan, my hometown city.

The idea behind the conference is to try to animate central- and east-european Python and Ruby communities. By inviting experts we want to broaden our knowledge and undersanding of presented concepts. The conference is meant to serve the exchange of ideas on the scientific ground, that is use of mentioned languages for certain scientific problems like, for example, text parsing, and on the buisness ground, like use of Django or Rails for creating web applications.

The state of Plone

short talk presented by Maciej Dziergwa about current Plone situation - based on Matt Hamilton's PloneConf2009 talk. After the talk we had a short discussion about current situation of Polish Plone Community. Plone is still not popular in Poland as it is in Italy...

Compiled Websites with Plone, Django and SSI

very interesting talk by Łukasz Langa and Wojciech Lichota about Plone, Django and SSI deployment. Using stxnext.staticdeployment you can deploy Plone site to static files. You can add dynamic stuff (like commenting) using Django. Finally you can glue everything together using Apache SSI mod_include. If you need search engine you can use and integrate, everything what I've mentioned before, with Xapian (or Solr).
You can find slides here.

Caching techniques in Python

some interesting caching techniques explained by Michał Domański and Michał Chruszcz. In Plone world we already know plone.memoize - a decorator for caching the values of functions and methods. You can use it of course outside Zope/Plone environment. If you need something more - check out i.e. pylibmc. At the end they've covered also reverse proxy with Varnish.

I talk presentati sono stati 2:

1. Carneade, dar vita alle relazioni del mondo reale: Plone come gestore di organizzazioni
2. collective.amberjack: Plone come piattaforma per i tutorial

Tutto il materiale è già in linea.

Da un paio di mesi la Plone Foundation ha aperto un servizio di richiesta di idee per le prossime release.

in questo senso dichiara:

This forum exists to allow you to suggest and vote on ideas that you think could improve Plone. We can't guarantee that we'll implement everything that's added here, but this is a chance to influence the future direction of Plone.

alcune di queste idee sono state votate e stanno lavorando per includerle nella release 4:

• accettate
• completate
  

Puoi ovviamente proporre la tua idea, ma puoi anche votarne altre. Se ben  organizzati, si può anche creare un "gruppo di pressione" in modo che alcuni temi sentiti solo in certi ambiti vengano resi noti anche ai developers.

Un caso è quello dell'accessibilità, tema molto caldo in Italia per via della famigerata legge Stanca, e che in ambito internazionale ci declina semplicemente con un rispetto delle norme del W3C.

Chiaramente il Forum è internazionale e la lingua è quella inglese, ma con il nostro dizionario inglese di fiducia, nulla ci spaventa :)
