Twitter – Now the machines are syndicating us

RSS recursion is not a toy

… that was syndication for the sake of it.

That’s what I said, word for word. Then a colleague pointed out that I could have twitter automatically update from my blog or Blakepics. And all hell broke loose.

I didn’t like Twitter as another way of updating my blog, or having it throw up all over my Facebook status every time I opened up my Twitter-enabled fridge. But reaching out to new audiences, and the potential to bombard mobile phone networks every time I bounce from one country to the next… Well suddenly it’s become quite cool.

And yes, I admit – I was tempted to install the application to syndicate my Xbox 360 status as well. But I’m not sure I’m ready to spam everyone that much. Yet.

Upgrading Fedora 8 to Fedora 9

It’s time for another Fedora upgrade. Whilst the installations aren’t necessarily getting any better – fixing them is becoming a bit faster, because the problems are pretty similar every time and these notes I’m keeping are helping.

  1. System won”t boot. Met with a grub> prompt, and no menu
    • Boot the system from the DVD again, and select “rescue an install system”.
    • ‘chroot /mnt/sysimage/’
    • “nano /boot/grub/grub.conf”
    • Change this line, “root (hd2,0)” to root “(hd0,0)”. (I’m not sure why Grub seems incapable of finding the right hard drive to boot from each time… It doesn’t change.)
    • Uncomment the line at the top #boot
  2. Cyrus imapd won”t start. Complaining of library missing.
    • Upgrade Cyrus – “yum upgrade -y cyrus”
    • Restart the service – ‘service cyrus-imapd restart’
  3. Rss2imap no longer posts the messages into Cyrus IMAPD
    • Difficult to place the blame on this one. One turning on Rss2imap debug mode, I see i@m getting the error ‘Message contains bare newlines’, and although Rss2imap has posted the message. It’s been discarded by Cyrus. This is actually proper RFC behaviour for Cyrus – as message’s shouldn’t contain the broken ‘\n’ character, but rather ‘\r\n’. At the same time, I also think, ‘so what?’. Either way, the Cyrus behaviour has changed, or Mail::IMAPClient modules have.
    • So the fix… Edit Rss2imap\RSS2IMAPLIB\, and add the bold text.
       my $message = ($headers . $body);
      $message =~ s/\n/\r\n/g;
      utf8::encode ( $message );

       my $folder = $this->get_real_folder_name ($this->{'last-modified-folder'});
      $body =~ s/\n/\r\n/g;
      $this->{imap}->append_string ($folder, $body);

      You’ll notice we’ve replaced all the \n line endings with the more correct \r\n. Let’s just hope we don’t have to undo that later when the problem gets resolved elsewhere 😉

Remarkably, this was the first time the wireless card started up immediately after the upgrade, perhaps things are improving after all 😉
