A fun bug I once ran across

Here's an interesting and fun bug (in C) that I once ran across, yearsago. Suppose that you have a hash table, with entries chained off eachother in case of a hash collision, and a function to remove an elementfrom it that looks like this:

鐵人28建設報告：佢已經好威武地大大隻咁企左晌處，為隆重其事及紀念這歷史性時刻，開幕當日，神戸市長矢田立郎及大批達官貴人企業高曾紛紛出席，同場更有西裝畢挺的鐵人28合唱團助響聲勢。

我真的衷心敬佩並羨慕

雪文的創作肯定比我這個故事作者漫長而認真
這是漫畫天地工作室第二次改編我的作品了
他們十分客氣和尊重作者
每次改編

What is going on with faulted ZFS spares

Suppose that you have several pools with a shared spare disk. One dayyou reboot your machine, and suddenly ' zpool status ' for most of yourpools starts reporting that your spare is faulted:

# zpool status tank  pool: tank[...]config:       NAME       STATE    READ WRITE CKSUM[...]       spares         cXtYdZ   FAULTED  corrupted data

Unless you are running a very recent version of OpenSolaris, you willprobably be unable to zpool remove these faulted spares. If thishappens to you, do not try re
