I have a 47k x 47k adjacency matrix that is very sparse (at most 30 entries per row); my textual representation therefore is simply an adjacency list of connections between nodes for each row, e.g. node connections A B C D E B A C D C A E D A E A F F E G H I'd like to import this into a dataframe...

Hello everybody, Data is myd <- data.frame(id1=rep(c("a","b","c"),each=3),id2=rep(1:3,3),val=rnorm(9)) I want to get a cumulative sum over each of id1. trying aggregate does not work myd$pcum <- aggregate(myd[,c("val")],list(orig=myd$id1),cumsum) Please suggest a solution. In real the dataframe is huge so looping with for and subsetting is not a

Hi all, I'm pretty new to Gluster, and the company I work for uses it for storage across 2 data centres. An issue has cropped up fairly recently with regards to the self-heal mechanism. Occasionally the connection between these 2 Gluster servers breaks or drops momentarily. Due to the nature of the business it's highly likely that files have been written during this time. When the

I got overzealous with snapshot creation. Every 5 mins is a bad idea. Way too many. What''s the easiest way to delete the empty ones? zfs list takes FOREVER

thanks very much urban. this was very helpful. i have around 12500 users spread over 3 independent servers each having around 4000+ users i am using qmailtoaster, vpopmail, spamassassin and dovecot. in future i am planning to consolidate all using a HA cluster. if it is ok with you could you kindly share some information about your email server configuration. if you do not wish to put it on the

As I'm new to qemu/kvm, to figure out how networking performance can be improved, I went over the code and took some notes. As I did this, I tried to record ideas from recent discussions and ideas that came up on improving performance. Thus this list. This includes a partial overview of networking code in a virtual environment, with focus on performance: I'm only interested in sending
