Internet scale security: the impact of cheapness

Ten years ago or so, mass login and password guessing attacks wereessentially a non-issue; old news, an attack whose time had passed notonly because everyone knew how to counter them but because they had sucha low payoff that no one bothered doing the tedious work (and if someonedid, you pitied them).

Then the Internet happened and everything changed. Suddenly masspassword guessing attacks were not a theoretical issue; instead, theywere cluttering up your logs every day .This happened not because mass password

金融海嘯何時完結

忽發奇想

當黃金升到某個水平,美國捨得將8000噸黃金儲備慢慢套現,救銀行、樓市、債市、救自己fiscal deficit(視乎當時要救什麽),就是金融海嘯完結之時。

黃金在未來2年將會以倍數升。

出發啦 不要問那路在哪?


最近最喜歡聽的歌
是羅大佑,李宗盛,周華健,張震嶽組成的"縱貫線"唱的"亡命之徒"
喜歡歌詞的樂觀
喜歡幾個男人合唱的豪邁
更喜歡其中一句:"出發啦 不要問那路在哪? 迎風向前 是唯一的方法"
過去幾個月我都停留在周

Remember

Yesterday morning, my students asked me reasons for the way certain diseases behave. "This is the way it is," I answered. "All that is ever asked of you is that you have to remember it."

This is my mantra – one I seldom follow.

Despite my teaching others to memorize this and that, I have to admit that my own memory is in decline. There is no question that creativity declines throughout all those years in the medical school. Hey, decline in creativity after rote learning

有關 Acid3 測試

最近看電腦雜誌都開始用 Acid3 測試的瀏覽器對未來 Web 技術的支持度,但要留意 Acid3 的這麼一句:

To pass the test, a browser must use its default settings, the animation has to be smooth, the score has to end on 100/100, and the final page has to look exactly, pixel for pixel, like this reference rendering .

意思就是說,

For the purposes of turning off the irritating blinking cursor , there are three generations of gnome-terminal (so far; the Gnome people may yet change their minds again), each ofthem with a different way to do this. So it goes like this:

  • in the original version of gnome-terminal , there is a direct preferencefor this; in the General tab of each profile there is a 'Cursor blinks'option.

  • in the intermediate version of gnome-terminal , there is no optionin gnome-

大家都無辜,大家都受害

你怕不怕同善於不負責任的人打交道?

真不是樂事,有些人天賦異稟,就是有本事把本來屬於自己的責任當作是他人的事,總之一切逃避付出,卻終日企圖分享成果。

然而,善於推卸責任的人其實比不負責任的人可怕萬倍。

不負

致:白銀戰隊隊長孫柏文

好在早前我沒有信你這位 白銀戰隊隊長 ,買實白銀;反而經我精心研究後,轉頭黃金的懷抱(由$760水平買入),更不買實金,而是買期金,賺到盤滿boot滿。

今天黃金直衝上$1000,白銀卻停留在$15樓下,請問你這

An attraction of planet-style blog aggregators as your feed reader

I've recently realized an attraction of planet-style blog aggregations: by design, they haveno way to go back in the feed history. You get one page of entries(however larger that is configured to be), and that's it.

This sounds like a peculiar thing to be an attraction, but it means thatcompulsive information junkies with not enough spare time have no choicebut to let things go. We cannot wind up sitting on several thousandunread feed entries that we are theoretically going to
