how following linq statement work? here code: var list = new list<int>{1,2,4,5,6}; var = list.where(m => m%2 == 0); list.add(8); foreach (var in even) { console.writeline(i); } output: 2, 4, 6, 8 why not 2, 4, 6 ? the output 2,4,6,8 because of deferred execution . the query executed when query variable iterated over, not when query variable created. called deferred execution. -- suprotim agarwal, "deferred vs immediate query execution in linq" there execution called immediate query execution , useful caching query results. suprotim agarwal again: to force immediate execution of query not produce singleton value, can call tolist(), todictionary(), toarray(), count(), average() or max() method on query or query variable. these called conversion operators allow make copy/snapshot of result , access many times want, without need re-execute query. if want output 2,4,6 , use .tolist() : var list = new list<int...

suppose following in bash @ command prompt: cmd1;cmd2;cmd3 if cmd1 fails how bash not cmd2 . cmd1 && cmd2 && cmd3 explanation execute cmd1 . if fails, cmd2 , cmd3 not executed. why? because false logically anded else equal false , if cmd1 returns false there no need evaluate cmd2 , cmd3 . , reasoning, if cmd1 succeeds , cmd2 fails, don't execute cmd3 . note just make things little more confusing, posix systems (like linux , other unix variants) return 0 success , non-zero failure . so, when failure above false = non-zero = failure true = zero = success why? because numerical value of return code used indicate different failure codes. for example, $ ls /root ls: cannot open directory /root: permission denied $ echo $? 2 $ asdf asdf: command not found... $ echo $? 127 $ ls / bin boot data dev etc home lib ... $ echo $? 0 ls returns "1" minor problems , "2" more serious problems. bash...

i actorref may have been created. there standard way call context.actorfor and, if didn't return live actorref , call context.actorof ? vice versa fine (ie call context.actorof and, if actor exists, call context.actorfor ). first off: get-or-create can work if there 1 entity (otherwise never sure how created when find it). means parent of actor-to-be place put code. within actor quite straight-forward: val child = context.child(name) match { case none => context.actorof(props(...), name) case some(c) => c } please refrain using actorfor , deprecated in akka 2.2 good reason . in case context.child() want more efficiently.

i new opengl programming. know ndc ranges [-1, 1] on both axis 0,0 in center. trying increase range , doing via gltranslatef(0,0,-11.0f) gives me more room. but dont know new ndc range after gl call. can body please explain ? you need first try understand life of vertex in opengl pipeline (an example here ). otherwise find hard understand doing. can frustrating @ begining. the simple answer question ndc coordinates always in range of [-1, 1]. cannot change , shouldn't need change that. what do want change though, modelview , perspective matrices objects have more space in screen. example gltranslatef(0,0,-11.0f) command, moves object down on negative z axis (where "camera" looks @ default i.e. away eye). since object farther away seems smaller, have more screen space. another set of tutorials have personaly found helpful opengl es ground up (they iphone principles same)

i'll try keep basic. i'm trying run shell on server side (not client). i've broken down code it's pretty basic. right if run on client side using createobject("wscript.shell") 'document.write' user in browser. <script type="text/vbscript" > set shell = createobject("wscript.shell") set whoami = shell.exec("whoami") set whoamioutput = whoami.stdout strwhoamioutput = whoamioutput.readall document.write strwhoamioutput </script> now if change code run on server side: <script type="text/vbscript" > set shell = server.createobject("wscript.shell") set whoami = shell.exec("whoami") set whoamioutput = whoami.stdout strwhoamioutput = whoamioutput.readall document.write strwhoamioutput </script> i error in browser telling me 'object required: server' @ line 11. line 11 'server.createobject' line. missing here? thanks from 'docu...

sample data. i'm not sure how use code block system on yet. df <- data.frame(c(1,1,1,2,2,2,3,3,3),c(1990,1991,1992,1990,1991,1992,1990,1991,1992),c(1,2,3,3,2,1,2,1,3)) colnames(df) <- c("id", "year", "value") that generates simple matrix. id year value 1 1990 1 1 1991 2 1 1992 3 2 1990 3 2 1991 2 2 1992 1 3 1990 2 3 1991 1 3 1992 3 i sorting through r subsetting questions, , couldn't figure out second step in ddply function {plyr} applied it. logic: id subgroups, find highest value (which 3) @ earliest time point. i'm confused syntax use here. searching so, think ddply best choice, can't figure out how. ideally, output should vector of unique ids (as 1 selected, entire row taken it. isn't working in r me, best "logic" come with. ddply( (ddply(df,id)), year, which.min(value) ) e.g. id year value 1 1992 3 2 1990 3 3 1992 3 if 3 not...
