I accidentally found an article from a seminar notes on designing workflow system. The discussion part is very enlightening, especially for what I am looking for.

Workflow Environments Guide
This guide is excerpted from Chris Dwan (Bioteam). Original Link is here .
Interaction Service in Taverna 1.3.1
The majority of components within a workflow are computer based,
data sources, analysis algorithms and the like. In many analyses,
however, there is a requirement to interact with people as part of the
analysis process. This raises an issue – how can we define a human
interaction within a workflow? The solution adopted here is the
Interaction Service, an extensible mediation layer inbetween the
automated workflow system and a user or users.
Optimize MySQL for Ensembl
Yesterday my two concurrent mysqlimport process hangs the production mysql server. The two import process all shows “repair with keycache”. I am not sure why the repair command is issued, but as the “repair with keycache” takes forever and it eventually frozes the entire MySQLs, I have to optimze it.

好东西卖得快
今天又成功的把闲置了两年的有线路由器给卖掉了，35元。得到结论：好东西，价格公道，自然卖得快。
USB 2.0 PCI Card
I bought a USB 2.0 PCI card to work my external harddisk. The orginal cheap one uses VIA chip. It can be recognized in windows XP, but worked only at USB 1.1 speed (1.5MB/s). Later, I returned this one and replaced with a more expensive one using ALI chip. everything works perfectly now (20-30MB/s).
Propose “Pair Deployment”
This idea comes from “pair programming” in Extreme Programming. I proposed to Neal (cc: Kevin and Tim). Hope they will support.
最近买卖频繁
最近在逐渐卖掉一些闲置的电子产品，卖掉的感觉不错。Apple 的 那个 iSight 放了2年没有用了，今天有人 $80 买了。还有路由器，一台旧机器 (sold on $120) 和一些网线，希望卖掉的好。同时从公司拍卖得到机器硬盘太小，为了它能够接我的80G外接硬盘，还要买一个USB2.0的PCI卡和硬盘盒 (bought at 50$ total)，总之今天要搞定！
