bash script to backup compiled applescripts

#! /bin/bash

IFS=$(echo -en "\n\b")
for i in *.scpt
do
    osadecompile "$i" > "${i%.scpt}.applescript"
done

Here are some short scripts I use:

---- Clean Desktop.applescript
on run
    do shell script "chflags hidden ~/Desktop/*"
end run

---- Clutter Desktop.applescript
on run
    do shell script "chflags nohidden ~/Desktop/*"
end run

---- Eject and Sleep.applescript
tell application "Finder" to eject (every disk whose ejectable is true)
tell application "Finder" to sleep

---- Skip Forward 30 Seconds.applescript
tell application "iTunes" to set player position to (player position + 30)

Java regular expression: anchored versus unanchored greedy quantifier

Here's a simple Java program

$ cat Test.java
class Test
{
    public static void main (String args[])
    {
        System.out.println ("this".replaceAll (".*", "that"));
        System.out.println ("this".replaceAll ("^.*$", "that"));
    }
}

When compiled and run, it produces

$ javac Test.java
$ java Test
thatthat
that

What's up with that first replacement? Why is the "that" doubled? Beats me...

$ java -version

check_mk on OpenBSD

First, grab the most recent source, and extract and install it.

wget http://mathias-kettner.de/download/check_mk-1.2.2p2.tar.gz
gunzip check_mk-1.2.2p2.tar.gz
tar xf check_mk-1.2.2p2.tar
cd check_mk-1.2.2p2
gunzip agents.tar.gz
tar xf agents.tar
sudo cp check_mk_agent.openbsd /usr/local/bin/check_mk_agent
sudo chmod 755 /usr/local/bin/check_mk_agent

Then add the check_mk service to /etc/services.

Add the service to /etc/inetd.conf and restart inetd

$ sudo kill -HUP `cat /var/run/inetd.pid `

Open up the port in pf (and probably allow pings from the nagios host).
