Android: Calendar items set to tentative

Yay, I got myself a Samsung Galaxy SII. Great phone running Android!

There's just one thing that annoys the shit out of me: When I create a new agenda item in my google agenda, it shows up in my thunderbird as "tentative". These items will have a lower opacity, which makes the agenda harder to read.

I've google'd around, and found a lot of complaints about this problem, but there's no solution to make appointments confirmed right away. And I'm definitely not opening all items in thunderbird to confirm them by hand.

There's a simple solution to this problem: I made Thunderbird render the agenda differently. Using the file userChrome.css, I set opacity to 100%. (If you don't know what userChrome.css is, read this page at mozilla.org.) The actual CSS is:
calendar-event-box[invitation-status="TENTATIVE"],
calendar-editable-item[invitation-status="TENTATIVE"],
calendar-month-day-box-item[invitation-status="TENTATIVE"],
calendar-event-box[status="TENTATIVE"],
calendar-editable-item[status="TENTATIVE"],
calendar-month-day-box-item[status="TENTATIVE"]
{
opacity: 1 !important;
}

Restart thunderbird and you're done.

This "solution" does not set any appointments to "confirmed". It just renders tentative appointments the same as confirmed items, so that you don't see the difference anymore.

X11 over SSH

CentOS 5's and Fedora 15's base installations are pretty good prepared to use X11 over SSH. You just need to install one more package on the server you're connecting to: xorg-x11-xauth. According to yum info, the purpose of this package is:
xauth is used to edit and display the authorization information used in connecting to an X server.
This editting probably means synchronising X11 authority cookies between SSH peers.

Installing is done using:
yum install xorg-x11-xauth

Then ssh into the box using:
ssh -X [servername]

Funny: Change the HP Laserjet ‘ready’ message

To change the 'ready' message of a HP Laserjet, you can use the following script.

#!/usr/bin/perl
use strict;
use warnings;
 
unless (@ARGV) { print "usage: $0 <ip address> \"<message>\"\n" ; exit }
 
my $ip = $ARGV[0];
shift(@ARGV);
chomp $ip;
 
use IO::Socket;
my $socket = IO::Socket::INET->new(
	PeerAddr  => $ip, PeerPort  => "9100",
	Proto     => "tcp", Type      => SOCK_STREAM
	) or die "Could not create socket: $!";
 
print $socket "\e%-12345X\@PJL JOB\n\@PJL RDYMSG DISPLAY=\"@ARGV\"\n\@PJL EOJ\n\e%-12345X\n";

I've used this at the office, with a lot of hilarious reactions from my colleagues. Messages like:

  • Please insert kitten in tray 1
  • Please insert [name of colleague] in tray 1
  • Virus detected
