Playing With Tokyo Cabinet

I'm still playing with RDF, and while I'm at it, I'm now experimenting with Tokyo Cabinet and Tokyo Tyrant.

I rewrote my experimental triplestore using the Mikio Hirabayashi's software. Right now, I've got the Subjects, the Predicats, and the Literals stored in a Tokyo Cabinet Hash, the Triplets in a Tokyo Cabinet Table, and my abstract Node object (which is basically a set of Triplet) in Memcached.

I tried Tokyo Cabinet mostly because of the benchmarks, and indeed, I confirm, it's fast !

But also because I don't need all the features of a traditional RDBMS, and it really feels good to get rid of this complexity.

Nice Sunday afternoon hacking.

Update your feeds !

I just moved my blog from MT to TypePad. The feeds have moved too, you should subscribe again if you want to follow me:

• This blog feed

• The photoblog feed

The design is very simple for now, I'll play with the custom CSS feature in the next few days.

Playing with RDF

Rainy week-end in Paris, the sun waits until Sunday afternoon to show up, anyway I had good time hacking with perl, memcache and mysql.

I started to play with RDF, it came up like this.

The web apps in general are slowly moving from the traditional relational DB model, to something more flexible, schema less, and to something more scalable, distributed and heavy cached.

There are a lot of different components already existing, memcached, couchDB, Hadoop, ...

This is exciting, lot of innovations.

Back to RDF, I think that one way to go can be to store the objects in a triplestore. Kind of Semantic Web Object Mapping I you want. Every object has already a URI inside the app, plus, you get the notion of graph for free.

I started hacking something about this on my free time, at least as a good way to learn more about these technologies. If I manage to have it working, I'll probably share it on CPAN or github.

I loved LeWeb08

It's a quiet Sunday afternoon, four days after the conference, and I find myself thinking about what Chris Anderson said comparing the internet and the human brain, about the Open Stack and its ability to compete with closed environments, about the opposition between the Marc Simoncini's "rules" and the regular web2.0 business, ....

Every year these two days are the opportunity for me to take some distance with the everyday life, get inspired by great people and think about the future.

Congratulations Loïc and Geraldine !

PARIS (AFP) -- Les propriétaires d'ordinateurs récents seront soumis à la redevance TV (116 euros par an) parce qu'ils peuvent aussi recevoir la télévision, selon un amendement qui doit encore être adopté définitivement lors de l'examen du projet de loi audiovisuel à l'Assemblée nationale.

Freiner le développement d'internet pour financer le dinosaure France Television. Il n'y a que moi que ça choque ?

I saw these videos several times during the campaign, with always mixed feelings, you want to laugh, but, at the same it's so unbelievable and scary. Now that we know that the bad Disney movie was just a scenario, it's time to watch them again ... but just for fun !

GoogleBot "General HTTP error"

According to Google Webmaster Tools, GoogleBot had a problem crawling my blog on September 6th. It's described as a "General HTTP error", no HTTP error code, and the URLs are removed from the Google index, which is the most annoying obviously.

I sure my blog was online this day, so, I googled a little, and it looks like I'm not alone in this case, same problem here and here, also starting on September 6th.

Posting this note will ping the Google API, lets see if it helps GoogleBog to find its way to my blog again :-)

Update-17-09: It looks like Google is working on the problem.
Update-25-09: Still not fixed for me.
Update-15-10: Finally fixed, my Google traffic is slowly getting back.

Still using Vienna

7777 news to read in my aggregator, I said to myself, if you blog that you really have nothing else to blog, ... and that's true :-)

I should clean my feed list or spend more time reading them, but yes, I'm still using Vienna, (since this note). Not much activity on this open source project these days, is it dead ? Should I switch to something else ?
