会社のブログに若干の蛇足を書いたのでそちらも参考にしてほしい。

Software Industry History

1946: The First Computer
1961-1965: IBM OS 360
1975: Fred Brooks

Today
  - $500B HW/SW
  - $500B people and support

Money No Match for Security Design Flawas
 $100M MS
 $200M
 $400M
 $800M

Software Industry Not Alone
  Education
   - treats teachers like factory workers/students raw materials
   - bureaucracy
   - policy not science
  Agriculture
   - old: harmony, sustainable
   - now: one kind of food
  Manufacturing
   - 

Deming: The Courage to See The Crisis
  - low quality --> bad industry model
  - loyalty and trust
  - improve people withe training
  - transformation is the everybody's job

As We May Think
  1947: Vannervar Bush manifesto for World Wide Web
  1984: France:MiniTel
  1990: World Wide Web

User Innovation Toolkits (von Hippel, 2002)
  - 85% of all breakthorough innovation is user-driven
  - Proprietary innovation strategies stifle 5/6 of all innovation
  - some innovations (like the web) impossible with proprietary models

  old  ad/dev, design, build, test
       ---------------------- ----
       supplier               customer


  new  ad/dev, design, build, test
       ------- ------------------
       supplier customer

  democrotize innovation

Unleashing Innovation
  - sourceforge.net 1.2M users, 100K projects
  - 2002 and 2005 FLOSS surveys of OSS developers
  - 490K OSS developers spend 11+ hour/week on OSS
  - MORE THAN 5 Million HOURS PER WEEK
     - it's fun
     - it improves their skills
     - it's good for society
  - Microsoft employs 61,000 and spend $6B on R&D
     - 80 hours/week * 61,000 < 5M hours/week
     - $6B/Year @ $25/hour not enough to afford 5M hours/week
       - $2B fixing security bugs

Software Quality -- What Would Deming Do?
  - Typical software defect density is 20-30 defects per 1000 lines of code
  - 2004 -- Linux Kernel is 5.7 MLOC
     - should 100,000 defects
     - only found 985 found
  - 2005 -- 100% of serious bugs fixed in first 6 months
     - complexity increased 4.7%
     - density decreased 2.2%
     - end of mythical man month
  - 2006 -- 32 other OSS projects measured
     - worst (PHP) was still 50x better than typical 
       (or 98% fewer bugs per LOC)

Open Source is Changing The World
  - AIDS/ secrecy and competition
          
Improving Security by Making it Free
  - Deming: Security is everybody's job

New and Changed System Call

Q&A

topics
 - OSS Merit and Risk
 - OSS Project Management
 - Open Standards & Open Source
 - About MT and MT in the future

OSS Risk is ...
 - transparent development or broadcasting the vulnerability
   -- code review is the best practice
   -- not ideal situation
   -- there is no hide
   -- thouthands reviewers

OSS -- Can they develop/create the software
 - money > off shore
 - compete added value > best; compeate cost > worst
 - innovation > creation value
   more smart people out side
   OSS model optimise boundary
 - control --> power lose/get
   RH strategy $1B cach in Bank
   RH can not change the world
   RH meets the market/revolutional mind
   capitalism

Open Standards
 - Open Standard Requirement
 - The Criteria
   - No Secrets
   - Availability
   - Patents
   - No Agreements
   - No OSR-incompatible

Q&A session
 - RH does not accept patch etc from Ikeda san's question
   RH partner / open source development
   best way to find it
   propriety model service improvements < open source model

マイケル・ティーマン氏のプレゼンの後に岡田さんが質問するという形式だったのだが、フロアからも2つ質問する機会があったので、ずーずーしくも質問した。
