嘉賓：莫宜端
節目裡講到以前覺得寫評論是一件刺激的事，嗚，有時想補充這種感覺是在學院裡比較強烈，好像有了學院的屏藩才比較容易感到刺激。現在有時真的想做到喜愛的說喜愛、討厭的說討厭就於願

Some useful new Linux software RAID features
Courtesy of a pointer from the linux-kernel mailing list to the Gentoowiki entry ,here's two useful (relatively) new software RAID features:
- Normally, if a RAID array goes out of sync the kernel assumes everythingon the out of date drive(s) has to be rewritten. With write-intent bitmapsthe kernel keeps track of what areas actually got written to and onlyresyncs them.
(This brings Linux up to more or less parity with an equivalent SolarisDiskSuite feature.)

Handling lines with something-separated fields for Python
As a system administrator, I spend a bunch of my time dealing withfiles made up of lines that are composed of fields separated by somecharacter. A classical example is /etc/passwd , with colon-separatedfields. These file formats are ordered lists with named fields, whichshould sound familiar , but they don't showup as Python lists, they show up as lines of text and they want tobe output as text; that we use lists to represent them is just animplementation detail.

On useful front-panel LEDs
I moved up to ADSL recently and it's quite nice, but I miss one thingabout my old Supra modem: I've been spoiled by its luxurious front paneldisplay. The front panel of my ADSL modem is somewhat of a letdown andI've been missing information that I used to be able to get at a glance,in particular how saturated my link is.
The ADSL modem has four front-panel LEDs, all equally prominent:

由於全城追蹤所謂特首「選舉」及徐步高新聞，3月2日早上1130有13名天星示威者，無聲無息地被派還保釋金，不需保釋了。咁即係咪唔再告呢？滿差館的人都好好笑容，招呼前唔該後，但沒人回答我們為什麼發還
我的林夕字傳
讀中學的時候，我很喜歡兩位作者的散文，一位是亦舒，另一位，是林夕。 亦舒的散文，單是文字的簡潔已值得學習，林夕吸引我的，是他看世事世情時的外冷內熱，還有變化多端的表達手法。當年他出過三本散文集，分別是《
A story of network weirdness
We have a number of internal networks here . One of them is a port-isolated subnet forgeneral user machines (such as Windows laptops), where the port isolationmakes sure that user machines can't talk to each other and thus can'tinfect each other. One day, an alert user on the port isolated networkreported to us that his machine was seeing packets from the outsideworld destined for a completely different machine.
