i have sparse dgtmatrix matrix package, has picked duplicate colnames . want combine these summing columns same names, forming reduced matrix. i found this post , adapted sparse matrix operations. but: it's still slow on large objects. wondering if has better solution operates directly on indexed elements of sparse matrix faster. instance, a@j indexes (from zero) labels in a@dimnames[[2]] , compacted , used reindex a@j . (note: why used triplet sparse matrix form rather matrix default of column-sparse matrixes since figuring out p value makes head hurt every time.) require(matrix) # set (triplet) sparsematrix <- sparsematrix(i = c(1, 2, 1, 2, 1, 2), j = 1:6, x = rep(1:3, 2), givecsparse = false, dimnames = list(paste0("r", 1:2), rep(letters[1:3], 2))) ## 2 x 6 sparse matrix of class "dgtmatrix" ## b c b c ## r1 1 . 3 . 2 . ## r2 . 2 . 1 . 3 str(a) ## formal class 'dgtmatrix' [package "mat...

akka actor can process 1 message @ time , hence dont need worry concurrency. consider have system pizza shop. design this 1)webservice 2)akka ecosystem actors pizaacreater, deliveryhandler 3)web service accepts ther order , passes pizzacreater,pizzacreater creates pizza , passes deliveryhanlder. now there 1 instance of pizzacreater , deliveryhandler.this slow down entire system. 1)should create multiple pizzacreaters , deliveryhandler? 2)how customerservice pass order pizzacreater minimum load or how pizzacreater pass pizza delivieryhandler minimum load then? 3)is creating multiple instance of pizzacreaters / deliveryhandler ok? if "pizza creation" blocking operation (uses network/db) create router pizzacreatorworkers (the number of workers/threads depends on scenario). if "pizza creation" non-blocking - create 1 actor per request. same thing delivery: create router fixed number of deliveryhandles if delivery blocking otherwise create actor...

i trying write java program specific words in string. have working part doesnt seem match if word match first or last word in string. here example: "trying find first word".matches(".*[^a-z]find[^a-z].*") //returns true "trying find first word".matches(".*[^a-z]trying[^a-z].*") //returns false "trying find first word".matches(".*[^a-z]word[^a-z].*") //returns false any idea how make match on word in string? thanks in advance, craig the problem character class before , after words [^a-z] - think want word boundary character \b (as per colind's comment) opposed not character in a-z range. pointed out in comments (thanks) you'll needs handle start , end of string cases. so try, eg: "(?:^|.*\b)trying(?:\b.*|$)"
