盛況空前
下機後開啟手提電話。
嘩。
收到四個不同男人發出的短訊。
中英法日俱全。
發生了甚麼事？
近來香港女人很缺貨嗎？
題外話。
世上最錯的事就是當男人打電話給你你認不出他的聲音還用另一個男人的名字喚他。

What do Unix errno values mean?
Here's a philosophical question: what do Unix errno values mean?
One possible meaning is that they are hints about why your systemcall failed. Another possible meaning is that they specify what wentwrong; in the extreme, a system call can only fail for certain specificreasons, each of which is associated with a specific errno value.
Errno as a hint is essentially the traditional Unix view. V7 Unix didn'teven document specific error returns for system calls, and Bell Labstook it to the logical

大爺 吃早餐了
曲：楊友仁
詞：黃孫權、楊友仁

我的家鄉 離的遠
無法帶走 所有思念
來不及吃 的早餐
卻成了家園 的預言

RPC is surprisingly expensive
Once, long ago, I did a distributed computing project course where Itried to speed up a drawing program by moving its expensive floatingpoint calculations (I believe it needed to calculate square roots forsomething) to a machine with a much faster CPU and floating point. Weused Sun's RPC/XDR for this because it was both a great match for whatwe were doing and the obvious choice at the time, among other reasons.
Rather to our surprise the drawing program just didn't get much faster
Extra security systems for Unix should be explicit, not implicit
I'm no fan of SELinux, but in stumbling over it a few times I've come tosome theories about why I don't think it works. One of them, perhaps themost important one, is this:
Extra Unix security stuff needs to be simple and explicit .
