八十年代，廟街的精美唱片，是我幾乎隔天便去打躉的地方。
那個時候，我剛上中學，開始迷戀在黑膠唱片上轉下轉下轉出來的美妙聲音。我甚麼都愛聽，古典、爵士、中外古今的流行音樂，通通都不放過。

A peculiar change in Linux flock() and fcntl() behavior
Here is one of those fun issues that cause me to pull out my hair(although it can give me a peculiar sense of satisfaction to track itdown).
Suppose that you have two filenames, such as (not entirelyhypothetically) .vacation.dir and .vacation.pag . As it happens,these filenames are actually hardlinks, so there is only one actualfile involved. Now, suppose you have code that is like this C-oidpseudo-code:
fl = {F_WRLCK, SEEKThinking like a security paranoid: an example
There's been a bunch of commotion lately over OpenSSH and how perhapsthere's a 0-day exploit in an older version of it, and so on. Giventhis, clearly the thing to do is upgrade to a current version justin case, right?
If you think this, you're not thinking like a security paranoid.Allow me to illustrate.
Imagine that you are an attacker. You've found a vulnerability inthe very latest and most recent version of OpenSSH, and you want
楷模在遠，o靚模在近

Packages should not contain both tools and policies
If you install the Ubuntu mdadm package on a machine with nosoftware RAID arrays, it will 'helpfully' email you every dayto report:
checkarray: W: no active MD arrays found.
checkarray: W: (maybe uninstall the mdadm package?)

Minimalistic spam, another annoyance to worry about
I've started getting advance fee fraud spam which have as their entirecontents something like this:
You won Three Million Pounds.contact Anita Meyer :
At first I was amused by the minimalism and lack of effort on thespammer's part; it'd be hard to get an advance fee fraud attempt in lesswords. But the more I think about it, the more that I think this may bemore clever than it looks (whether or not it's deliberate).

The importance of making an issue visible
One of the things that's started to help the program energy efficiencyissue on Linux is the developmentand popularization of programs like
iotopandpowertop. For thefirst time, people could conveniently get a simple overview of what wasgoing on with IO and power on their system and, not surprisingly, peoplereacted to what they saw.This provides a handy illustration of the importance of making anissue or a behavior visible to people, both to users and especially toprogrammers.
