較早前在本blog寫了一篇有關Levi’s 廣告攣與直的網誌，港台的Eric看後，便找了我上了他和梁兆輝主持的節目「自己人」做嘉賓，講一下gay marketing這題目。
噢，想來我真的和港台有緣，今次已經是第二次被不同的DJ邀請，看來DJ們都經
Why I think identity blurs into authority
In theory we can separate the ideas of identity and authorization,and it is common to present complex computer systems this way. Inpractice I think that many people blur the two together and attemptingto forcefully separate them only leads to confused users and frustratedsecurity people.
I believe that one reason for this is because we rarely think ofpeople alone in the real world; instead we think of them with attachedassociations. It is not 'Chris Siebenmann, who is authorized to', it is'Chris Siebenmann who works

Getting your networks to your racks
I'm in the process of getting a new test server installed in a rackin our machine room.

A gotcha with command order in pipes
Here's a mistake I've made more than once:
tail -f active-log | grep big-filter | grep -v one-thing
