Why web spiders should not crawl syndication feeds

On the surface, crawling syndication feeds looks like an attractive ideafor web spider operators (although I am not convinced that the metadatathey get is on the whole any better than the metadata on web pages).But as things are today, it is a terrible idea and is highly likely toprovoke bad reactions if attempted.

The big problem is that right now, if you turned a web spider loose onsyndication feeds it would pull far too many of them. This is becausepeople (and websites) have lots


創意與集體回憶 – 低清老翻王

be kind rewind

Jack Black 向來不是我的那杯茶,總是覺得他太造作,表情動作說話都誇張過了頭。但因為《低清老翻王》的故事蠻有趣,所以還是進場了。而事實上,此片的確也不算拍得好看,即使是片中的翻拍短片,也只能算是好笑,但不聰明。


怎樣的學生怎樣的學校

一個人怎麼會不能理解災民的痛苦呢?其中一個原因是,長期以來這個人生活在一個不講求理解的環境裡。熊貓女生在網上已受到公審,而其中學竟還動用私刑,要將女生記大過。校規裡定義的「大過」,如何有權延伸到個人的

天災之後

四川大地震,死亡人數已達六萬人,在5月12日下午,多少孩子像平常一樣上學,多少人在當地過着正常的生活,然後在頃刻之間,山崩地震,從此與家人永別。

天災難測,生命無常,這段日子我們留心關於地震的新聞,首先


Freedom

The Prime Minister despised the idea that someone teaches him how to spend the money in my last story. But could it really be wrong to exercise his freedom of choice? This reminds me of the argument on clinical freedom, long cherished by medical doctors as essential to effective practice. Can a doctor be as noble as the Prime Minister to claim (or reclaim) the freedom to make his/her own choice in terms of medical expenditure?

If you wish to (it is not really necessary), we can regard

What promiscuous mode does on modern networks

Recently, I have wound up wondering if using or not using tcpdump 's -p switch made any difference on modern hardware and modern switchednetworks (partly because not using it causes your kernel to generate amessage every time you start and stop tcpdump , and I can live withoutthat). The somewhat unfortunate answer is that yes, it still makes adifference.

First, promiscuous mode is still at least partly a low level hardwarething in your network card, not just a software switch inside thenetworking stack.

終於還是沒有跑過死神
上路孩子,天堂裡沒有豆腐渣
也沒有做不完的作業
唱不完的讚歌
也沒有人拿著火把到處奔走
也沒有人逼著你愛誰恨誰

山崩地裂的那一刻,孩子
其實只要換

善人

以前傳聞謝某常拖著滿箱過期的書籍回大學還書,並因此想像出我其實也當過這樣的聖誕老人(把書和罰款送到圖書館),但其實我並沒有這樣做過。

倒是今天,我終於拖著一個裝滿書的喼穿州過省。謝謝黎健強!

Prime Minister

The dreams that I made over the last few days have been overwhelmingly trembling. You didn't believe me? I didn't think you would.

Anyhow, I went to meet the Prime Minister and got a chance to speak to him, in my dream of course. We spoke about the seismology and pre-detection of earthquake. Needless to say, this is a controversial subject. "Isn't it better to keep track of warning sign than knowing nothing at all, Prime Minister?" I suggested
