Zwiki is a Wiki engine based on Zope which allows you to build Wiki Webs (easy-to-edit, flexible, collaborative Web sites) in the Zope environment.
Zwiki is an easy-to-use, fun, and powerful wiki engine based on the Zope web application server; it also works well with the Plone CMS.
Main features:
- simple and fuzzy urls
- automatic page hierarchy and subtopics links
- smooth two-way mail integration
- RSS
- issue tracking
- dynamic scripting
- a variety of text markups including RestructuredText, MoinMoin and LaTeX
- WYSIWYG and external editing
- fine-grained security
- strong internationalization support
Enhancements:
Installing
- Wiki pages in Plone (or CMF) will no longer show the metadata tab by default.
- add isDefaultPageInFolder method, fixing plone 2.5.x support (#1283)
Configuring
- dont use # in setupTrackers event log messages, it was confusing
Browsing
- dont limit the content area to 80% width in standard skins stylesheet
- clean up plone/cmf tabs/actions
- change backlinks forms title to Related pages
- in the PAGE/myvotes view, link to pages
Editing
- tweak the warning a user sees when too many external links are added
- make restructured text be more silent about errors (report severe errors only)
- LaTeX support: add the zwiki.org version of LatexWiki to Zwikis standard plugins (Simon Michael, Bob McElrath, Open Software Services)
- Axiom, Reduce, Maxima, Noweb support: add the zwiki.org version of MathAction to Zwikis standard plugins (Simon Michael, Bill Page)
- increase max page name length in editform from 100 to 300 for eg latexwiki formula page names
Issue tracking
- make the add issue form respect the edits_need_username property, closing a spam hole (#1279)
Translations
- new Breton translation for plone skin (Fulup)
- translation updates: - German (Stefan Kose) - Japanese (Masaya Kato) - Russian (Valery Sharapov)
General
- in embedded DTML, ensure the context object (_.this) can acquire from the folder, as wed expect. Zope bug ? see collector

mod_jsp is a JSP handling module for Apache 2. It works by starting and maintaining its own application server (based on Jetty).

It can then continually manage the application servers virtual host filesystem mappings from the data passed from Apache.

BoomBasster is a music player that runs under DirectFB.

BoomBasster plays any type of music file that is supported by FusionSound.

The user interface uses alpha blending and works well with touchscreens.

BoomBasster is supposed to be used with the mouse.

Styx is a scanner and parser generator designed to address some shortcomings of the traditional lex/yacc combination.
It has unique features like automatic derivation of depth grammar, production of the derivation tree including its C interface which provides access to the abstract syntax tree, preservation of full source information and pretty printing to faciliate source-source translation, persistence to aid rapid interpreter writing.
For application in contemporary computing environments, it supports unicode, reentrancy and offers thread-safeness.
Last but not least, Styx works well under many different OSes, among them dos, windows, and serveral unixes.
It has been successfully used in many applications and is known to provide rapid compiler development. Both from our practical experience as well as from the amount of written code, the gain in development time for realistic languages versus lex/yacc is a factor of about 5-10.
Enhancements:
- fixes panic mode error recovery
- fixes token buffer restriction. The token length is now of type long.
- hopefully fixes some configure problems on freeBSD (concerning libdl)
- adds parsing support for binary files

SyncEvolution project synchronizes Evolutions contact, calender and task items via SyncML. The items are exchanged in the vCard 2.1 or 3.0 format and iCalender 2.0 format via the open source Funambol C++ client API library, which should make SyncEvolution compatible with the majority of SyncML servers (but see under known problems). Full, one-way and incremental synchronization of items are supported.
SyncEvolution does not synchronize with another SyncML capable device or another computer directly. A SyncML server that that device and SyncEvolution can talk to is needed. There are several options for that:
using a web service like ScheduleWorld which stores the data to be synchronized on a ScheduleWorld server and provides access to it via SyncML
installing a SyncML server like the free one from Funambol (www.funambol.com) on ones own server
installing a SyncML server on the desktop
The recommended solution is ScheduleWorld because it is easier than setting up a server and provides better support for vCard and iCalendar data than the stock Funambol server installation. Setting up a server on the desktop has the additional problem that not all mobile devices can communicate with the desktop via HTTP.
With a server that fully supports SyncML and vCard/iCalender the following works:
copy a complete database to the server and restore it from the server later
delete or modify an item locally, then make the same change on the server
delete, modify or add items on the server (by synchronizing with another client), then make the same change locally
conflict resolution (where two clients modify the same item, then sync with the server) is handled by the server, but SyncEvolution has support which ensures that no data is lost by creating duplicates
For conflict resolution and synchronization between clients which support different attributes of items the server needs an understanding of the format of items. The Funambol server supports that for contacts, but not yet for the calendar events and tasks that SyncEvolution sends. ScheduleWorld also works with SyncEvolution and calendars plus tasks.
Enhancements:
- This is the first release with full support for synchronizing of Evolutions contacts, calendars, and task lists.
- It was extensively tested with ScheduleWorld (sync.scheduleworld.com).
- This Web based service is easy to use and a lot of effort went into ensuring that it works well together with SyncEvolution and Evolutions PIM data.
