iSCSI versus NFS

These days, an increasing number of storage appliances can do both NFSfileservice and iSCSI (generally using the same underlying pool of diskspace), which has resulted in me seeing an increasing number of peoplewho are wondering which one they should use.

There are two things wrong with this message. The first is a RHELbug; Red Hat should have made sure that this cron job didn't bombardsysadmins with unimportant messages by, for example, redirectingstandard error to /dev/null .

(This is sadly a general problem


計算名場面

每一套經典,都必須要有一個名場面。

就像Terminator中阿諾的那一句 "I will be back",沒有那一幕,就不是經典;又像男兒當入樽裏,三井跪在地哭著說「好想打籃球」;又像楊過苦等十六載,約定之日一夜白頭,悲痛縱身一跳;沒有名

Catholic Programmer's T-Shirt and Mousepad

Reposted from Open Source Catholic :

A realization about why my inbox keeps being my to-do tracker

I have a problem. It's not a unique or novel problem; I understand it'sone that a lot of people have. My problem is that over time my emailinbox quietly winds up getting used as my to-do tracker, basicallyregardless of how I'm theoretically trying to keep track of this stuff.I leave messages in my inbox to remind me to do things, and the latestgo-round of this has now reached the point where I email myself notesabout things I want
