! Tiki Suite
__Going beyond Tiki Wiki CMS Groupware__
Server, Web, Desktop and Mobile suite

{img type="src" src="http://suite.tiki.org/img/tiki/Tiki_Suite.png" link="http://suite.tiki.org/" noDrawIcon="y"}

! Tiki Suite
Tiki Suite is a selection of Free and Open Source Software (FOSS) server, web, mobile and desktop apps with a concerted effort for greater interoperability and security, which is aimed at small & medium-sized organizations. The Tiki Suite is especially suited to decentralized and knowledge-centric organizations and offers the features that what 80% of the people use 80% of the time (collaboration, office productivity, publishing, etc.). Features include: Email + Wiki + CMS + Groupware + Commerce + Accounting + Document Management + CRM + Web conferencing + Desktop sharing + PBX VOIP Telephony + Instant messaging & presence + Video management + E-learning, etc.

! Intro

Think of an organization you know of with a staff of 10 to 100
* When will 80% of them be using just Web Applications 80% of the time? 
* When does the main unit of information becomes a web page instead of a file?
* Now? 1 year? 2 years? 5 years 10 years? Never?

"Skate to where the puck will be" --Wayne Gretzky

! Why the name?
* It's a suite of applications around Tiki
* Suite means "next step" in French, so "next step for Tiki"
* But what is Tiki?

__Software made the Wiki Way__ 

Like Wikipedia but to build a web application instead of knowledge

__The Open Source Web application with the most built-in features. There are so many, we had to add a search engine!__

__Other popular apps have a different model: small core + loads of functionality in 3rd party add-ons.__
{SPLIT}


! But...
* __No hunting__ around to find the best 3rd party module
* No needing to __re-install 3rd party modules__ at every upgrade, hoping they all still work!
* Because, in Tiki, everything is built-in and developers __collaborate__ on and __extend__ features, instead of just cooperating around a core (when they are not just outright competing...). And __upgrades are easy__!
* Do you have two wiki pages for the same thing? No. Why would it be so for features?
* More later about the model, let's describe some features!

tiki.org/Model

! Benefits & challenges
Offers __benefits__
* Tons of features, without duplication, excellent code re-use and code review, more collaboration, tight integration, easy upgrades, excellent interaction between features, etc.
* Permits huge changes between versions __because__ we don't have to worry about breaking 3rd party extensions.
But does bring __challenges__
* Huge code base to maintain.
* Admin panels
** hundreds of features
** with a total of over 1200 settings/options! (we had to add a search!)
* Learning curve: 1200+ pages of documentation
* What should be sensible defaults?

! Why this evolution?
* Tiki: the Open Source Web App with most built-in features
* Tiki is PHP / MySQL / Zend Framework / Smarty / jQuery
* But starting to be limited by its technology (PHP/MySQL/JavaScript on __shared hosting__) to address all the needs. Some functionality, like video management, doesn't make sense in PHP/MySQL.

! Use case
{SPLIT()}
* 10 to 100 employees
* External consultants, partners & volunteers
* Multilingual, distributed & mobile work force
* Knowledge workers
---
* CMS / Portal / Blog / Publishing
* Intranet / Extranet / Collaboration / Document Management / Wiki / Groupware / Project Management / Forms / Framework
* CRM / Customer support / Social Networking
* E-Commerce / ERP / Accounting
* Online training / tech support / Issue tracker
* Web conferencing / chat / telephony
* Etc.
{SPLIT}
This represents __millions__ of organizations

! Challenges of IT systems
* Multiple systems
* Diverse needs
* Desktop centric
* Difficult to do tech support
* Interoperability is very difficult

! Zawinski's Law
* Zawinski's Law of Software Envelopment (also known as Zawinski's Law) relates the pressure of popularity to the phenomenon of software bloat.
* "Every program attempts to expand until it can read mail. Those programs which cannot so expand are replaced by ones which can."

Coping with Zawinski's Law: When planes crash, do we blame gravity? We must cope with this! Even if you don't like a law, it doesn't mean it doesn't apply :-)
* 37 signals in the book "Getting Real" : "Goodbye to bloat. Simple, focused software that does just what you need and nothing you don't"
* In an Community Open Source project, it'll be difficult to get consensus on what is "__needed__" and what is __bloat__.

! Intertwingularity
* EVERYTHING IS DEEPLY INTERTWINGLED. In an important sense there are no "subjects" at all; there is only all knowledge, since the cross-connections among the myriad topics of this world simply cannot be divided up neatly.
* Hierarchical and sequential structures, especially popular since Gutenberg, are usually forced and artificial. Intertwingularity is not generally acknowledged—people keep pretending they can make things hierarchical, categorizable and sequential when they can't. --Ted Nelson
[http://en.wikipedia.org/wiki/Intertwingularity|en.wikipedia.org/wiki/Intertwingularity]
[http://www.shirky.com/writings/ontology_overrated.html|shirky.com/writings/ontology_overrated.html]


! Overlap & interoperability
* __Best of breed__ vs. __suites__ vs. __feature bloat__
* While Ted Nelson coined "Intertwingularity" to express the "complexity of interrelations in human knowledge", it's the same problem for software. There will always be overlap.
* Apple controls both the hardware and the software which make it much simpler (drivers, UI, etc.)
* Every app claims interoperability (ex.: via open standards)
** It's very hard! Even within apps of a same publisher!

! Trend to suites
* Because of Zawinksi's law, intertwingularity and the progressive move to Web Applications, more & more apps and SaaS will offer "everything".
* "It's best to do one thing really, really well." –Google
* Google started just with search. And now? :-)

! SaaS
* A number of companies are offering (or will one day offer) "manage your organization in the cloud"
* Google Apps, Zoho, NetSuite, Salesforce, Microsoft, SAP, IBM, Apple, Facebook, Oracle, Yahoo!, etc.
* Interoperability will remain a challenge.
* If you want to use FOSS, there are no readily available complete solutions. You need to make you own "cocktail" of applications.

! Second half of the Chessboard
* "In technology strategy, the second half of the chessboard is a phrase, coined by Ray Kurzweil, in reference to the point where an exponentially growing factor begins to have a significant economic impact on an organization's overall business strategy."
**[http://en.wikipedia.org/wiki/Wheat_and_chessboard_problem#Second_half_of_the_chessboard|en.wikipedia.org/wiki/Wheat_and_chessboard_problem#Second_half_of_the_chessboard]

The more features / systems there are, the more interoperability is desired / needed and the complexity increases faster and faster. How can we keep the complexity level on first half of chessboard?

Also see:[http://en.wikipedia.org/wiki/Combinatorial_explosion|en.wikipedia.org/wiki/Combinatorial_explosion]

! The delicate balance
* "Make things as simple as possible, but not simpler" --Albert Einstein
* Use as few apps as possible, but as many as needed. Bonus points to all-in-one apps and libs that maintain the interoperability of their components (ex.: BigBlueButton, Zend Framework)
* As technology evolves, push things to the browser (ex.: spellchecker, HTML5, jQuery)

! Linux Kernel
"In later discussions Torvalds explained the reasons for its choice: a fully modular architecture, like the one adopted for HURD, would have posed problems to a degree of complexity that it could have compromised the accomplishment of the project. To avoid such risks and keep the degree of complexity of the project as low as possible, Torvalds decided to design a monolith and he actually wrote all the architectural specs himself, avoiding all the problems related to collective projects (e.g. division of labor, coordination, communication). On the other hand, the HURD micro–kernel, a project in direct competition with the Linux kernel, has paid for the choice of pursuing a fully modular approach from the beginning in terms of the continuous delays that have plagued its development. Nowadays, it is still under active development and still lacks the stability and performance assured by the Linux kernel."

Lessons from Free/Open Source Software by A. Narduzzo & A. Rossi

! CMF approach
* Some content management frameworks offer a common platform with thousands of extensions, which you pick & tailor to your needs.
* Better than "best of breed approach", but still suffers from "Combinatorial explosion" for interoperability. Drupal: 7500 modules Joomla!: 7000 extensions Almost each install with have a different combination of modules and versions. In Tiki, the code base is identical, and only the preferences configuration differs.
* Distributions are helpful here. However, "Paradox of choice" for extensions (compatibility and abandoned modules, upgrade difficulties, etc) leads to a 2-3 year release cycle for the core, which is too slow.

! Tiki NIH Syndrome?
"Not Invented Here (NIH) is a term used to describe persistent social, corporate or institutional culture that avoids using or buying already existing products, research or knowledge because of their external origins. It is normally used in a pejorative sense, and may be considered an anti-pattern." Source: Wikipedia

Half of the code in Tiki comes from other projects!
