Troubleshooting versus support

When we talk about 'support', especially things like 'vendor support',I think that there are actually two general things that are gettinglumped under the same label: issues that you could have dealt with onyour own if you knew enough, and things that are broken.

Although I don't have really good names for them, let's call the firstsort of issue 'troubleshooting' and the second sort 'support'.

Unless the vendor dropped the ball on their documentation (which iscertainly


Solaris 9 'Power management'

I had another Solaris 9 learning experience today: I came in to findmy ssh sessions to my Ultra 10 test machine dead, because the machinewas powered off. This was more than a little bit disconcerting, sincethe last thing I had left it doing was installing the current Solaris 9patch set. (It took sufficiently long that I'd had to go home before itfinished.)

Powering the machine on showed not a normal boot sequence, but amessage about restoring the system. This caused me


Exploring some spamblogs

I have a certain interest in the behavior of MSNbot, theMSN Search web spider. I'd like to keep track of what other people aresaying about it in blogs; the obvious way is a date-based [msnbot]search using Google Blogsearch.

Three levels of database usage

One of the perennial programmer debates can be caricatured as a threeway fight between adherents of MySQL , PostgreSQL , and Oracle (or the big irondatabase of your choice). As an example, you can see a recent roundstarting itself up here and here (both arguing what could be called the MySQL side).

Some time back it struck me that one way to think about how programsrelate to SQL databases is that they can be doing it at threedifferent conceptual levels. (And now that I have a


浪費

差不多一個星期了,

不論吃下多少,

美味的家常的難吃的,

最後還是吐出來。

勉強多吃一點,

亦只落得嘔吐胃痛。

與其這樣,

不如不吃。

你不讓我吃,

我就不吃。

First irritations with Solaris 9

As with Fedora Core 4 , I haven't beenusing Solaris 9 long enough to have given it a fair shake. So insteadof any sort of review, this is just a collection of things that haveirritated me about it on first exposure.

I'll start with a nice simple one:

# useradd -m -c 'Chris Siebenmann' cks
UX: useradd: ERROR: Unable to create the home directory: Operation not applicable.

This is on a default configured Solaris 9 machine, straight out of

明光社舉辦中學教育的人權課程 ,是很驚嚇。不過,早前為此事search到明光社的主頁,發現2004到2006的人權課程,也是由明光社舉辦的——他們都不知辦了多少年了。這更驚嚇,不是嗎?

電影與遊戲

看今期的《電影雙週刊》的副刊《ForeignFilms》 (第49期) 裏面有一專題「遊戲:電影終結者」,講的是近年來由電影改編而成的遊戲的掘起,用了很多篇幅介紹了一些電影改編的遊戲,並提出隨著遊戲越來越真實,而又比起電影有更
