web karma / leaveyourmessagehere
someone said to me in amsterdam that I have good tourist karma. Today I have good web karma.
from boingboing.net I wandered to web zen which inspired me to go to leaveyourmessagehere.
the idea at this place is simple: a text-input box and a button “leave your message here”.
under this creativity pressure I wrote this:
come to kaiserslautern. I am there and I miss you.
after pressing the hardest button, I saw the last message there (5 hours ago)
Thinking of you P……..do you miss me?
web karma: your spirit is so in tune with the web spirit that you react to things you conciously cannot know.

may the farm be with you. This fan/advertisment/starwarsrippoff movie has it all: good effort, good quality, rippoff.
btw: the real force is called JESUS. all this star wars fuzz keeps me off my own disciple/jedi training….
never move your foaf file2
michael notes that one could use http redirect and that clients should update their links when finding one of these.
After a permanent http redirect of a uri (hence also a semantic web uri) all triples and so should be updated.
some clients forget to do this and show the new data but keep the old uri.
never move your foaf file
practical rdf failure:
I moved my foaf file from gnowsis.com/leo/foaf.xml to http://www.leobard.net/foaf.xml – that has been a year ago.
still many foaf files have their seeAlso set to the old url. So I wrote to eaon/Michael Zeltner to update his foaf file at
http://zine.niij.org/data/foaf
he replied that his foaf file is now:
http://zine.niij.org/data/about-me
so we both moved our files. and crawlers / search engines like this here for eaon or this for me or that for me still have the outdated data.

great. another light switched on in the web.
uri crisis – one approach
a nice approach for identifying thigs with uris (known as the uri crisis) is the taguri.
note that taguris are not wise to be used with things that have already a http:… uri. And in my opinion, using any existing wiki system to make a URI has the same outcome as taguri and is easier to handle for the lesser deamons. (we, the high arcane sorcerers of semweb, have a domain, know how to use a date and can live with a uri that points to nirwana on the http space. lesser demons enter uris into browsers)
but despite these flawbacks, taguri is a nice idea.
thanks to andy seaborne for mentioning it to me.
dtmf’ing my light remote
the plan: to remotely turn on and off lights in my appartment, I need to plug my 433Mhz remote light control to my DTMF phone.
why? When standing on the bar “21” we cannot identify our own house, so it would be nice to switch the lights on/off from afar. The 21 os located in the 21st floor of a high building in kaiserslautern, so theoretically we could see our flat (from our flat, we see the bar).
The hack: idea would be the use one of these babies (a DTMF decoder) and call my own phone, then transfer the DTMF signals to a manipulated remote control. Alternase tively we could place some 230V relais at the DTMF decoder. Hm, how to pick up a phone automatically? could use the answering machine for that.
alternative approach: have a friend sit at home and do the lights on call. Perhaps attach a beer to the friend.
Semantic Web School and Semantic Web Information
an interesting thing happening in Austria is the Semantic Web School. The aim of this school is to preach the gospel of the semantic web to the masses, especially industry, government and end users.
The website has information about the school (in german) and the offered curriculum. They offer a set of one day workshops about several topics. The events are spread over several months (see navbar on left) and can be booked seperately. Cost is ok, compared to the quality of the speakers it is surely worth it (and regarding the good connections you get to the other industry & govn attendees 🙂 At the moment, courses are ongoing.
A very nice thing about the website is the good collection of information about the semantic web at large, they collect much info. They also asked their speakers to contribute there, so expect a quite well kept library of semantic web stuff.
Look at the right side of the nav bars to find the good links.
and yes, I am also giving a workshop there, about the dirty and good RDF tools: redland, jena, sesame, protege, gnowsis. I am looking forward to this, its on 25th may, you can still book to watch me.
