- Keynote : Eric Allman
- 介紹 sendmail,雖然說大家都開始使用公用的電子郵件(如:Gmail、Yahoo!、Hotmail等),但為了資料隱私安全性,講者還是建議應該要自行架設 mail server。
- 在討論串中,有人分享了以前架設的經驗 - How To Install Postfix, Dovecot, Amavis, ClamAV, and Spamassassin (Etch)
- <*> Advanced C Coding For Fun! - Rusty Russell
- <1> Kernel development: how it goes wrong and why you should be a part of it anyway - Jonathan Corbet
- Lesson 1 : get merged into main tree - 讓程式被納入主要核心開發
- 開發是孤獨的,team
- <2> Orchestrating the Intelligent Web with Apache Mahout - Aneesha Bakharia
/opt/mahout$ bin/mahout /opt/mahout$ bin/mahout kmeans -help
/opt/mahout$ bin/mahout seqdirectory -i <input> -o <seq-output> /opt/mahout$ bin/mahout seq2sparse -i <seq-output> -o <vector-sparse>
- parallel FPGrowth algorism
- Latent Dirichlet Allocation (LDA) 可以幫忙做話題分類
Word 1 | Word 2 | Word n | |
Topic 1 | 0.5 | 0 | 1 |
Topic 2 | 0 | 0.5 | 0 |
Word 1 | Word 2 | Word n | |
Doc 1 | 1 | 0 | 0 |
Doc 2 | 0 | 1 | 0 |
Doc n | 1 | 0 | 1 |
/opt/mahout$ bin/mahout lda -input <PATH> .... (skipped)
- k-mean 的 k 分類要靠經驗,LDA 的 k 分類也是要嘗試,如果能夠結合 WordNet 的語意屬性,或許會更容易做語意網。

Autonomic Computing
- What is autonomic computing?
As a scientific discipline, autonomic computing encompasses the study of systems that are capable of autonomously achieving desired behaviors. The systems are often called self-* systems, where * is a placeholder for the type of behavior. For example, self-tuned systems are capable of tuning their performance as needed by their intended mission; self-protected systems automatically deal with intrusion attacks. Self-managed systems do not require manual configuration and updating, and self-healing systems are capable of repairing themselves. Self-managed systems can also be more broadly construed as being capable of managing all behaviors mentioned above.
