With it, you could run rsync to update a

Hi everyone, I ve been using R for months and find it really practical and straight forward. However (the inevitable however), I am finding it very slow for one of my operations: it s basically an itertation over i and j in a pretty big table (4* 4608). It takes 30 minutes!!!! Thanks Ps:if it can help here is the source: median1<-matrix(nrow=4608,ncol=1)

I''m finding that I''m writing sets of very similar scenarios to check access permissions for each of my actions. Does anyone have suggestions on how to dry this up: Given an existing Account And a logged in Admin When the user visits account/manage Then he should get access Given an existing Account And a logged in Manager When the user visits account/manage Then he should get

Replacing my current media server with another larger capacity media server. Also switching over to solaris/zfs. Anyhow we have 24 drive capacity. These are for large sequential access (large media files) used by no more than 3 or 5 users at a time. I''m inquiring as to what the best configuration for this is for vdevs. I''m considering the following configurations 4 x x6

Would it be worthwhile to implement heuristics to auto-tune ''recordsize'', or would that not be worth the effort? -- Regards, Jeremy
