i creating application , want create applications fast scale. use java jetty servers, cassandra database , solr search engine. should use loadbalancer infront of jetty servers whole setup can scale. i've read mod_jk , apache i've read doesn't scale many machines due beeing programmed in c. should use? should try , program myself in java? want use non sticky sessions. so apache work fine reverse proxy, more or team familiar with. without sticky sessions pretty easy things work. nginx or haproxy looking though if need bigger. scale horizontally more trick of not having sticky sessions (which have covered) fronting dns round robining work. really not sure mean programming being in c doesn't have scaling things horizontally or vertically. thats more of architecture thing language used implement it.

i have javascript following <script type="text/javascript"> var login = "<sec:authentication property="principal.username"/>"; </script> when see value of login is abc&#64;gmail&#46;com. what want must abc@gmail.com. is there way can correct lo-gin , not weird symbols. know why such weird symbols occurring instead of proper symbols. &#64; , &#46; html codes @ , . respectively. as far know there isin't native function decode such string in javascript. can use parsing ability of dom elements. var login = (login = document.createelement('span'), login.innerhtml = 'abc&#64;gmail&#46;com', login.textcontent); you can wrap functionality in function reuse: function decodehtml(text) { var el = document.createelement('span'); return el.innerhtml = text, el.textcontent; } decodehtml('abc&#64;gmail&#46;com');

i need determine whether particular table rows unique on particular columns. i'm doing using subquery so: select t1.id, (select count(*) mytable t2 (t2.firstname = t1.firstname) , (t2.surname = t1.surname) ) cnt mytable t1 t1.id in (100, 101, 102); which works fine. however, i'd know if knows of more efficient way of achieving same result using subquery. i'm doing on azure sql server, way. you use group this: select t1.firstname, t1.surname, count(t1.id) cnt mytable t1 t1.id in (100, 101, 102) group t1.firstname, t1.surname order cnt desc you can add having cnt > 1 after group clause if want filter dupplicates. however, depends if need id column well, if do, might have use subquery. here can find more information on subject: http://technet.microsoft.com/en-us/library/ms177673.aspx

take @ execution plan: http://sdrv.ms/1aglg7k it’s not estimated, it’s actual. actual execution took 30 minutes . select second statement (takes 47.8% of total execution time – 15 minutes). @ top operation in statement – view clustered index seek on _security_tuple4. operation costs 51.2% of statement – 7 minutes. the view contains 0.5m rows (for reference, log2(0.5m) ~= 19 – mere 19 steps given index tree node size two, in reality higher). result of operator 0 rows (doesn’t match estimate, never mind now). actual executions – zero. so question is : how bleep take 7 minutes?! (and of course, how fix it?) edit : some clarification on i'm asking here . not interested in general performance-related advice, such "look @ indexes", "look @ sizes", "parameter sniffing", "different execution plans different data", etc. know already, can kind of analysis myself. what need know what cause 1 particular clustered index seek slow...

i'd group data based on interaction of 2 variables, map aesthetic 1 of variables. (the other variable represents replicates should, in theory, equivalent each other). can find inelegant ways this, seems there ought more elegant way it. for example # data frame 2 continuous variables , 2 factors set.seed(0) x <- rep(1:10, 4) y <- c(rep(1:10, 2)+rnorm(20)/5, rep(6:15, 2) + rnorm(20)/5) treatment <- gl(2, 20, 40, labels=letters[1:2]) replicate <- gl(2, 10, 40) d <- data.frame(x=x, y=y, treatment=treatment, replicate=replicate) ggplot(d, aes(x=x, y=y, colour=treatment, shape=replicate)) + geom_point() + geom_line() this gets right, except don't want represent points different shapes. seems group=interaction(treatment, replicate) (e.g based on this question , geom_line() still connects points in different groups: ggplot(d, aes(x=x, y=y, colour=treatment, group=interaction("treatment", "replicate"))) + geom_point() + geom_li...
