So bad day today, I'm having the absolutely worst hangovers since that incident back at that bar in yeah whatever - massive pain.

Okay so i spent most of the day trying not to feel my head too much. But now i guess its time to do some work.

I saw another site slightly like mine called wallpipe.com. It looks nice, but it still suffers from the twitter / facebook problem of me being spammed with irrelevant comments from people i only halfway know.

I am quite worringly now starting to use wallrush.com though there's hardly any content. Specifically i feel a need to be able to browse through the videos so this is what I am implementing today. Maybe I'll also fix the remaining add content sections and change some of the design a bit.

Favicon.ico

Yeah well I'm making some sideprojects for real green cash, so wallrush.com is not developing as fast as I desire. However last night I finally made some progress, so now there's a script for importing the title and favicon of linked sites. I think that's kind of cool. Next up is improving the RSS importer, finalizing the sign up, and add pages, and making a better design of the wall.

Some time ago I read a very interesting article, about a competition by netflix.com (read more) where the point is to make a program that can predict users opinions of a new movie based on previous judgements of other movies.

The authors of the article had noted that no matter which method was used for prediction none of the competitors could get closer than 90%-95% (i think) accuracy in their estimates. The really interesting thing was that though very sophisticated mathematical methods yielded better results it was about 2%-3% better than simple methods.

Obviously this means you can use a lot of time being slightly better, but you should consider if it is worth it. That might be the case if you want storm predictions or something like that. But for a "simple" social entertainment site 90% is properly going to be as good for at start as 95%.

So I am opting for a "simple" method of deciding wheter content is relevant for the user. More on this later - gotta feed my self :)

All right. So I have been writing about my WallRush.com project.

I am currently modifying the sql that retrieves content. As declared I want the content to be relevant for me (the user). To do this I have normalized personal popularity and age of the content and then weighted these when sorting for relevance. This won't suffice, I will have to include people of similar tastes evaluation of the content in the weighting before its good, but it still manages to retrieve the 3 videos in the base that I think is coolest right now :)

It will be fun to see how the SQL server will act if there are many request, since the SQL is not exactly "ressource friendly".

Well some its been some time now. I have bought a new domain name WallRush.com, which I think is quite good. I am currently trying to make my self make the site, which involves lots of coca cola, pizza and candy.

The idea is that i don't find facebook.com og twitter very interesting. Almost everything that people put up is worthless selfpromotion. I do the same of course, but that doesn't make it interesting. I want a site that will:

a) Alert me of social events like parties, birthdays, valentines day and so forth.

b) Present me with funny, important or exciting news, videos, blogs, songs and pictures.

c) I want the site to (in-a-google-smart-way) to know how to prioritize this content for me, but i always want to be confronted with new/seemingly irrelevant entertainment/knowledge, so that i can choose to develop my taste in new directions.

So far so good. I have been doing a lot of coding, and I am about to discard it all because of JS crossbrowser problems, lack of animation etc. I think a classic site design is properly the best way now.

So why this post? Because i need it to test the RSS import feature ;)
