The Revolution Will Not Be Televised

It will more likely be broadcast on IPTV via Drupal

Or live–blogged on Twitter

Or photo–journaled on Facebook

Wait — they just were.

The pace of technology innovation continues to
increase every year

The biggest sites on the Web, the largest stores of
data, the fasted–growing platforms: all Open Source

Open Source Initiative

While Open Source projects dated back to early 90’s
there was need for a formal definition/declaration

OSI founded in 1998

Provided the framework for trust, community,
distribution that has allowed Open Source to flourish

SourceForge.net hosts ~8400 Open Source projects

Thousands more hosted on Github.com

Why OSS Is So Critical

It’s an enabler

We can build on the shoulders of giants
(giant communities that is)

When we’re not wasting time reinventing the wheel,
we can move on to the rest of the car

With the fundamentals are covered, we have the
freedom to truly innovate & make connections we
couldn’t before imagine

(Please save us from ever having to build a CMS again)

The Realm Of The CMS

Content Management Systems (CMS) are the new black

Logical extension of static HTML given the availability
of robust web serving, database & scripting platforms

Essential part of communication functions for schools

Multiple users with multiple permissions able to
Create, Edit & Archive content (Articles, Blogs, Press
Releases, Events, Stores)

Simplicity is paramount

CMS Licensing: 3 Models

Proprietary/Custom: cost for development & licensing

Boxed System (stand–alone): cost for licensing, slow/
inflexible upgrade cycle

Vignette, Ektron, SharePoint

Open Source: can be downloaded & installed for free

The big 3: Wordpress, Joomla, Drupal

Many more: Mod X, Typo 3, Dot Net Nuke, Plone, Zope

Open Source CMS Benefits

No licensing fees — still pay for development but BIG
differentiator when compared with proprietary

Flexibility to accommodate growth, new content,
services & features…increased customization

With proprietary, changes require foresight, time & money

Wisdom & strength of wide development community

With proprietary, tied to specific developer

Stable code — always being bettered by larger
community of developers

Open Source ‘Big Three’

(there are many others, but these are most common)

Based on xAMP stack (OS/Apache/MySQL/PHP)

All allow custom presentation layer/themes

All allow robust data integration

Wide range of advantages/disadvantages

All have their fans & sweet–spots

Only as good as the developer involved

Joomla

One of most popular with significant library of theme
templates

More ‘out–of–the–box’ functionality

But less flexible & not as much room for growth

Less editing functionality (as compared to WordPress)
– need 3rd party tools for image manipulation

Greater security risk with vulnerable plug–ins
(according to recent HP security risk assessment)

Security Comparisons

Eyes on the code:
how many is enough?

Proprietary systems are built by
small numbers of
developers
(often far fewer than 100)

According to HP Security Report each of the ‘Big 3’
have made huge strides in recent years

Wordpress, Joomla had
~200 developers
contribute
to latest core updates

Drupal 7 had
~1,000 contributors
& now runs
every patch & module through battery of
~30,000
automated tests
before approval
