fixed effects linear model in R
...ith "vce(cluster id)"
My question is : how could I do that with R ?
An important point is that I have too many individuals, therefore I cannot include dummies and should use the demeaning "usual" procedure.
I tried with the plm package with the "within" option, but R quikcly tells me that the memory limits are attained (I have over 10go ram!) while the dataset is only 700mo (about 50 000 individuals, highly unbalanced)

Encoding speed
I tried to encode two minutes from an AVI DV file 720x480:

ffmpeg2theora the same in about 2 minutes or more.
The FLV quality it's quite good, some dropped frames maybe.

Drb Connection error on multiple dispatch.fcgi ''s
Hi All,
I''m using Backgroundrb as a general purpose long-running-task back-end
