A Thought on a Reasoner-enabled Version of Del.icio.us (and perhaps Technorati)

I have been adding more bookmarks to my del.icio.us account and have begun tagging them with RDF-like object/datatype properties. Adding more and more object/datatype properties to the bookmark, a provoking thought popped up:

It would be nice if tagging can be assisted by ontologies and a logic reasoner. Look at del.icio.us/thitiv. The _hasAffilication:CUPhoto property should be a subproperty of _hasAffiliation:Chula (provided that CUPhoto stands for Chula Photo Club.) Also, aticles on 'tagging' are subclass of articles on 'metadata'. But articles on 'metadata' are not essentially the articles on 'tagging'. 'Friends' versus 'people' is also another example. Bookmarks about my friends are of course bookmarks about people. But not all the people I know or found on the Internet (through search engines) are my friends. Ontology-assisted tagging sounds promising to solve this problem.

In principle, this problem is partly related to what mentioned in the MIT's Piggy Bank paper submitted for International Semantic Web Conference (ISWC) 2005 and I am looking into it.

iTunes: Error 261 while Burning Data CDs/DVDs

Apple Discussions: 261 error while burning MP3 CD. I usually put an aphostrophe (') in the name of playlists and was having error 261 burning CD/DVD data discs since iTunes 5.1. Upgrading to iTunes 6.0 for Windows doesn't help. I was burning a music DVD this morning and had Error 261 again. So I went to Apple iTunes Discussions site and look for a thread on this. Viola! There are many people having the same problem as mine. The thread ends at a point where someone removing ampersands, the '&' symbols, from their playlists and could avoid this error. I tried removing aphostrophes from the name of my playlist because aphostrophe falls into the kind of non-alphabet characters that needs escaping in some programming languages. It works!!

Microsoft Office Outlook Connector 12.1 Beta 2 Crashes Thai Language Input in Outlook 2007

It's been more than a year since I last blogged. I've been busy with work and also don't know what to blog. Here comes my new findings: Microsoft Office Outlook Connector 12.1 Beta 2 + Outlook 2007 + Thai Language Input = CRASH This has also been proven here . I downloaded the Outlook Connector the other night for improved supports to Windows Live Hotmail -- only to find that whenever I start typing e-mails in Thai, i.e., hit the "language switch" key Outlook simply crashes! I googled for " outlook 2007 crash language switch " this morning and find someone having the same Outlook Connector insta.led and the same problem as mine. So, Outlook Connector is most likely the cause of trouble. I uninstalled Outlook Connector this morning and, yes, typing in Thai doesn't crash Outlook 2007 anymore!

MPICH2: mpdboot failure due to conflicting /etc/hosts entry

One single line in the /etc/hosts file on my Ubuntu Linux machine wasted my precious whole afternoon. I had some assumptions about the cause of this problem but I don't want to spend too much time investigating on what really caused the trouble. Anyway, here are the listings of what worked and what didn't: /etc/hostname ubuntu mpd.hosts.cluster master worker-01 Bad /etc/hosts 127.0.0.1 localhost localhost.localdomain ubuntu 192.168.200.128 master 192.168.200.129 worker-01 Result thitiv@ubuntu:~$ mpdboot -n 2 -f mpd.hosts.cluster thitiv@master's password: mpdboot_ubuntu (handle_mpd_output 359): failed to ping mpd on master; recvd output={} Good /etc/hosts 127.0.0.1 localhost localhost.localdomain 192.168.200.128 ubuntu master 192.168.200.129 worker-01 Result thitiv@ubuntu:~$ mpdboot -n 2 -f mpd.hosts.cluster thitiv@worker-01's password: thitiv@ubuntu:~$ At this point, with the /etc/hosts now fixed, the MPICH2 cluster could be booted up successfully. I don't want t...
