Tiki Suite

Going beyond Tiki Wiki CMS Groupware
Server, Web, Desktop and Mobile suite

Tiki Suite

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?

Tiki: The general idea

Software made the Wiki Way

• Like Wikipedia, but for code instead of content
• The general direction of computing -> everything is going to the browser (Firefox, Chrome, Safari, Explorer, Opera, and mobile browsers) -> The client.
• The Server is a collection of software installed on a server and designed to generate HTML/JavaScript for these browsers.
• Tiki is the Free / Libre / Open Source Web Application with the most built-in features. It runs on top of other software (MySQL, PHP that the user doesn't see)

Tiki Wiki CMS Groupware

Hundreds of built-in features

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!

• All-in-one codebase
  • Inherent synchronized releases
• Lots of features, but no duplication
  • Do you have two wiki pages for the same thing? No. So, why would it be so for features?
• Dogfood

• Scheduled releases (twice per year)
  • LTS every third release, with 5 year support

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.
• Less code for the community to maintain: http://en.wikipedia.org/wiki/Technical_debt
• No abandoned module, because a new shiny one just came out
• No dependency hell (needing to re-install 3rd party modules at every upgrade, hoping they all still work!)
• No hunting around to find the best 3rd party module

But does bring challenges

• Huge code base to maintain
• Admin panels with hundreds of features for a total of over 1200 settings/options! (we had to add a search!)
• Learning curve: 1200+ pages of documentation
• What should be sensible defaults?

More about complexity and files

Tiki 12.2 ships with 14 803 Files (and 1 979 Folders)
Included from other projects (/vendor & /vendor_extra): 7511 Files, 1316 Folders
Maintained by the Tiki community: 7,292 Files, 663 Folders

So Tiki contains about 15k files and the FLOSS Web application with the most built-in features (by far)

About half the code in Tiki is maintained by the Tiki community and the other half is re-using code from external libraries like Smarty, Zend Framework, jQuery, etc. Maintaining code from other projects is work. We need to keep it up to date, and upstream fixes and enhancements. But it's a lot less work than maintaining ourselves. We are counting on the experience, energy and expertise of a larger community.

So say we maintain about 7 or 8k files. Sounds like quite a bit, but let's put this into perspective:

• Joomla! has 8351 "extensions"
• Drupal has 27 604 "modules"
• WordPress has 32 912 "plugins"

Tiki covers the vast majority of features that these 3 systems offer via the thousands of extensions. So just about any project you could do with Joomla!, WordPress or Drupal, you could also do it with Tiki.

Yet, they have more extensions to maintain than we have files! (and since they can't possibly maintain them all, it leads to dead-end extensions and disappointed end-users).

See: https://tiki.org/Coping+with+Complexity
http://en.wikipedia.org/wiki/Technical_debt

profiles.tiki.org

Instead of having thousands of extensions, we collaborate on the code base, and can make very specific apps thanks to profiles.

• Value of a free source project
  • Beyond code: the community and the experience
  • Combining the different features, producing new benefits never imagined by the authors
  • How to share this knowledge?
• Profiles to configure your Tiki
  • On wiki pages (collaborative, version history, etc.)
  • Can be used not just at install, but at any time and can be combined
  • Not just for settings, but also for data
  • Since there is no extra code, can be designed for very specific, long tail uses

We can have hundreds of profiles for an out-of-the-box experience, with a single code-base!

How much is it "worth"?

• $20 million according to the Basic COCOMO model
  • https://www.ohloh.net/p/tikiwiki/estimated_cost
  • "Beyond just development time, COCOMO is meant to include the design, specification drafting, reviewing and management overhead that goes along with producing quality software."

• Yet, the Tiki Software Community Association (TSCA) has no employees
• Tiki doesn't depend on any funding from any company, foundation, government or anyone. It thrives thanks to the community.

Power users

• https://tiki.org/FLOSS+Web+Application+with+the+most+built-in+features
• Profiles: can use, share and build recipes to cater to diverse use cases

Devs

• Easy commit access
• Commit to trunk, stable within 6 months
• Collaborative community
• See https://doc.tiki.org/Framework
• Profiles: can build very specific applications, without custom code

SysAdmin

• Designed for shared hosting (PHP/MySQL)
• LTS versions
  • Tiki12LTS supported until November 2018
  • Can go from LTS to LTS or even skip one or two LTS (5 year support)
• Easy upgrades
• See benefits for https://tiki.org/Hosting+Company

Mass deployments

• Tiki Remote Instance Manager -> TRIM
• In other web apps, if you have 300 projects, you can have up to 300 code bases, because of various extensions (or you have unhappy users because you didn't install their favourite extension). If you have 300 Tiki projects, you have 1 shared code base
  • You can restrict or force features or preferences thanks to the System Configuration tool
• Profiles: can deploy a configuration to hundreds of instances

Why this evolution?

• Tiki: the Free / Libre / Open Source Web App with most built-in features
• Tiki is PHP / MySQL / Zend Framework / Smarty / jQuery (and Bootstrap in Tiki13)
• 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

This represents millions of organizations

Challenges of IT systems

• Multiple systems
  • Dozens & dozens of software, most of which are not interoperable
  • Difficult to upgrade
• Silos
• Diverse needs
• Desktop & file centric, even in 2014
• 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 FLOSS 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

en.wikipedia.org/wiki/Intertwingularity
shirky.com/writings/ontology_overrated.html

Overlap & interoperability & the Trend to suites

• 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!
• 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 FLOSS, there are no readily available complete solutions. You need to make you own "cocktail" of applications.

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:en.wikipedia.org/wiki/Combinatorial_explosion

• "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."

en.wikipedia.org/wiki/Wheat_and_chessboard_problem#Second_half_of_the_chessboard

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.: Openfire Meetings, 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

https://dev.tiki.org/Modularity

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: 27000+ modules Joomla!: 8000+ 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 2-4 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!

What is status of Tiki Suite?

• The good
  • Each component is fantastic, and the future is bright
  • All risky / major / strategic components have been selected, and they all fit well together, with minimal overlap
• The bad
  • It's still a manual process to assemble all the parts of the Suite (we are working on this)
  • Some less critical components (like Desktop virtualization) still need to be picked (but there are many good options)
• The ugly
  • Some components don't yet interoperate well even though they should (It proves the relevance of this project!)

How to pick apps?

• This is a long-term strategic decision
• Sound architecture/technology?
• Compatible license?
• Compatible community model?
• Active community?
• Same programming languages as us?
• Is SaaS available?
• Will the project be doing well in 5-10 years?

https://suite.tiki.org/Tiki+Suite+Component+critera
