I have to admit that I try to read more than I actually do, in particular blog posts. In this post I give you some links from 2010 that I now read skimmed a few weeks ago and found to be fresh enough to be shared again.

Talks from the Academic Year 2011/2012

Saturday, October 20th, 2012 | Author:

The new term has begun! And with it a new academic year in Freiburg.

In the past I used to put extensive notes online, for any talks I gave (mostly in local seminars at my university). I have changed this to posting blog posts instead, but sometimes I also have some teXed talk notes. The quality of the teXed notes is usually bad, as I didn't intend to publish them. This is a compilation of talk notes from the last academic year.

Goal for the next year: focus :-)

The term Web 2.0 was coined by Darcy DiNucci in 1999 and popularised by Tim O'Reilly in a 2004 conference named Web 2.0. In the beginning, it wasn't totally clear what Web 2.0 really meant for the ordinary web consumer. Then it crystallised out that users associate with the term Web 2.0 an interactive internet. During that time, the first large collaborative dynamic websites were seen, such as Wikipedia and YouTube. Web 1.0 are static HTML pages that don't allow interaction.

Categorical background for A¹-homotopy theory (simplicial model categories)

Monday, December 07th, 2009 | Author:

I decided to post some background needed in order to understand Morel-Voevodsky's paper "A¹-homotopy theory". I explain some notions of simplicial sets, topoi, monoidal categories, enriched categories and simplicial model categories.

I tried to give many more references I found useful.
