God and the Simpsons
Bart: All right! I've sat through Mercy and I sat through Forgiveness; finally we get to the good stuff!
Homer: Everybody's a sinner, except this guy!
Bart: Dear God, we paid for all this food ourselves, so thanks for nothing.
Homer: Dear Lord thank you for this microwave bounty, even though we don't deserve it. I mean...our kids are uncontrollable hellions. Pardon my French, but they act like savages! Did You see them at the picnic? Of course You did; You're everywhere, You're omnivorous. O Lord! Why did you spite me with this family?!
Marge: Dear Lord, if you spare this town from becoming a smoking hole in the ground, I'll try to be a better Christian. I don't know what I can do...Mmm...oh, the next time there's a canned food drive, I'll give the poor something they'll actually like instead of old lima beans and pumpkin mix.
Homer: God, if you really are a God, you'll get me tickets to that game.
advertisement: In honor of the birth of our savior, Try-N-Save is open all Christmas.
Bart: Christmas is a time when people of all religions come together to worship Jesus Christ.
(When listening to "You Light Up my Life")
Homer: I bet the guy she was singing that about was real happy.
Marge: Well, actually, she was singing about God.
Homer: Oh, well, He's always happy. No, wait, He's always mad...
Homer: The Lord is vengeful. O Spiteful One, show me who to smite and he shall be smoten!
Bart: I'm Bart Simpson, who the Hell are you?

TED: Ideas Worth Spreading
第一次聽到 TED 也是最近的事, 因為 MIT 那個超紅的 The Sixth Sense 影片.
youtube上可以看到很多 TED 的演講影片, 有空應該要多看看, 知道一下別人的 idea!

You Light Up My Life
剛剛看 The Simpsons Season 3 Episode 12 (8F10) 時聽到的.
劇情是 Marge 和 Homer 在車上聽到廣播裡的這首歌.
In Homer's car (complete with `DISCO SUCKS' bumper sticker), they sing
`You Light Up My Life' along with the radio, though Homer has trouble
with the words.
Marge: [listening to `You Light Up My Life' on the radio] Our song.
Homer: I bet the guy she was singing that about was real happy.
Marge: Well, actually, she was singing about God.
Homer: Oh, well, He's always happy. No, wait, He's always mad...

還有人寫了篇文章在分析:
Though he claims to be a Christian [41], Homer is essentially a pagan. Religion for him consists of placating or bribing an angry god or gods. Marge, listening to "You Light Up My Life", reminds Homer that this was their song. Homer replies that the guy she was singing about must have been real happy but Marge says that the song was about God. Homer: "Oh well, He's always happy. No wait, He's always mad." [42] When his house catches fire while he is at home skipping Sunday church service, Homer draws a conclusion about the nature of God. "The Lord is vengeful. [He falls on his knees]. O Spiteful One, show me who to smite and he shall be smoten!" [43]

MapReduce vs. Parallel Database
先是有一篇 Google 的 MapReduce paper (OSDI '04).
再來有一篇 Brown/Wisconsin/Yale/MS/MIT 的 paper, 主旨是說 MapReduce 的 performance 完全比不上 modern parallel database (SIGMOD '09).
現在是 Google 陣營要戰了 (Communications of the ACM '10):
The query languages built into parallel database systems are also used to express the type of computations supported by MapReduce. A 2009 paper by Andrew Pavlo et al. (referred to here as the "comparison paper"13) compared the performance of MapReduce and parallel databases. It evaluated the open source Hadoop implementation10 of the MapReduce programming model, DBMS-X (an unidentified commercial database system), and Vertica (a column-store database system from a company co-founded by one of the authors of the comparison paper). Earlier blog posts by some of the paper's authors characterized MapReduce as "a major step backwards."5,6 In this article, we address several misconceptions about MapReduce in these three publications:
* MapReduce cannot use indices and implies a full scan of all input data;
* MapReduce input and outputs are always simple files in a file system; and
* MapReduce requires the use of inefficient textual data formats.
We also discuss other important issues:
* MapReduce is storage-system independent and can process data without first requiring it to be loaded into a database. In many cases, it is possible to run 50 or more separate MapReduce analyses in complete passes over the data before it is possible to load the data into a database and complete a single analysis;
* Complicated transformations are often easier to express in MapReduce than in SQL; and
* Many conclusions in the comparison paper were based on implementation and evaluation shortcomings not fundamental to the MapReduce model; we discuss these shortcomings later in this article.
We encourage readers to read the original MapReduce paper and the comparison paper for more context.
http://cacm.acm.org/magazines/2010/1/55744-mapreduce-a-flexible-data-processing-tool/fulltext
最後一句話, 用白話文來說, 意思差不多就是"你回去多讀個幾年書再來戰吧".

Word vs. Latex
"閣下對於 latex 的質疑淺薄地令人覺得可笑
那跟 latex 的方便性比起來根本就是微不足道"
"我倒是也想問問您，您真的有用過 latex 嗎？"
"更何況，各大期刊會議應該都有提供 latex template
您到底有多少參數要調？您還是用使用 word 的心態在 latex 上嗎？"
這位老兄八成是工學院的學生, 搞不好還資工系的. 還真會引戰~
想我以前也是打死不碰Latex, 不過現在...五斗米力量大啊~
