2Overview
- Identify some popular open source apps
- Define Open and Open Access (OA)
- Examine why OA works (theory)
- Challenges of OA (model)
- Open computer networks (quick)
- Discuss common OA concerns and specific OA
challenges for colleges
3Open Source
- Languages and databases (PHP)
- Directories (Open LDAP)
- Software (OpenOffice.org, FireFox)
- Operating systems (Linux)
- Web software (Apache/Tomcat)
- Think tanks (eclipse.org)
- Hundreds more
4For Colleges
- Course management systems
- Moodle
- Angel Learning (hybrid open/ proprietary)
- Flat World Knowledge free textbooks
- Connexions Rice University project
- iPaper MIT Open Education project
5What is OA?
SYSTEM X
6OA Component Parts
- Open applications
- Open devices
- Open services
- Open networks
7Why OA?
- Collaboration
- SARS
- Hannys Voorwerp
- Spirit of education
- OA academic journals
- OA to information for learning (MIT)
- Lower costs (e.g. open source software)
- Customization
A high school teacher from the Netherlands
discovered an unexplained astronomical object,
named Hanneys Voorwerp, when the public was
invited to classify millions of galaxy photos in
an open project sponsored by the Sloan Digital
Sky Survey.
8Why Does OA Work?
- How does open access even work in the first
place? - Norms social organizations
- Trust and trust networks
- Importance of diversity
- Aggregating wisdom
- How far can trust go?
9Firefox Ubiquity Case
- Explanation
- Est. 250,000 d/ls
- As many Ubiquity
- extensions as general
- Firefox ones
- No security, no verification, no problem
- HUGE security concerns
- Proposed solution trust network rating system
10OA Challenges A Model
Freedom
Functionality
Security
Privacy
11 Privacy
- OA tipping point
- How much privacy to allow?
- Privacy anonymity
- Inversely related to open-ness
12 Security
- Human nature inherently good or evil?
- Called sewer monitoring
- Improperly tested
- code has back doors!
13 Functionality
- Does OA deliver everything we want it to?
- OA apps are customizable, (we never have to
settle) - OA plug-ins and add-ons raise security concerns
(recall Ubiquity)
14 Freedom
- Freedoms concerns
- Bandwidth
- Malware
- Ethical
- What to allow/ disallow?
- Filters, firewalls
- Total freedom chaos creativity

15Positive thought break
16Open Source Trivia
- What country was the first in the world to launch
100 open source software in education and
government? - Hint It was also the first country in the world
to have more cellular phones than landlines
17Hint This is a typical suburban schoolhouse
18Cambodia!
- Government and education are 100 open-source
- For Cambodia, its a question of resources
19XO Laptop Built for OA
- One Laptop Per Child (OLPC) open source XO
laptops - 433 MHz processor
- No hard drive
- Open networks are its specialty
- RSS news aggregator
The rugged, low-power XO laptop from OLPC is
entirely open source.
20Open Computer Networks
- Definition computer network that does not
require user authentication (i.e. log in/pw) - Unsecure (unencrypted)
- Convenient
- Safety numbers
21OA Concerns and Questions
- Expertise and support can be lacking
- Design flaws make security holes
- Are proprietary systems or OA systems a better
value? - Hidden costs
- Will proprietary systems integrate w/open ones?
22OA Challenges for Colleges
- CC Broader constituencies (open enrollment)
- College campuses change frequently
- Scarce resources (human and )
- Tight security policies take time to develop and
even more time to maintain - Whats best? often at odds with Whats
feasible?
23Conclusion/Questions
