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.

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:

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.

An irritating limitation of listening sockets
Traditional sockets implementations have an irritating limitation, atleast for TCP sockets: it is impossible to gracefully and cleanly shutdown listening (server) sockets.The problem is that kernels accept new TCP connections for listeningsockets without asking your server; accept() doesn't actually accept the connection, it just gives you the next one that the kernel hasalready accepted on your behalf.
This means that to shut down cleanly,you need a two-stage process: first you tell the kernel to stop acceptingnew connections
