i've written little haskell network example, don't know, port should use. i couldn't find example port number in ietf papers found or in wikipedia's list of port numbers , maybe there common port number in programming community. ports beyond 1024 , under 65535 , not have been used computer ok, choose like. net frameworks use 8000 or 8888.

this problem takes many forms. example, given input '(1 2 3 4 5 6), might want swap values between , odd pairs. output '(2 1 4 3 6 5). in haskell, rather easy: helper [] = [] helper [x] = [x] helper (x : y : ys) = y : x : helper ys i wrote clojure code accomplish same task, feel there cleaner way. suggestions on how improve this? (defn helper [[x y & ys]] (cond (nil? x) (list) (nil? y) (list x) :else (lazy-seq (cons y (cons x (helper ys)))))) ideally list consumed , produced lazily. thanks. (for [[a b] (partition 2 '(1 2 3 4 5 6)) [b a]] i) or resembling haskell version: (defn helper ([] (list)) ([x] (list x)) ([x y & r] (concat [y x] (apply helper r)))) (apply helper '(1 2 3 4 5 6))

i've stumbled upon sbt-pack plugin. development stream seems steady . it's surprising me believed plugin (quoting sbt-pack's headline) "creating distributable scala packages." sbt-assembly (among other features). what key differences between plugins? when should use 1 on other? (disclaimer: maintain sbt-assembly) sbt-assembly sbt-assembly creates fat jar - single jar file containing class files code , libraries. evolution, contains ways of resolving conflicts when multiple jars provide same file path (like config or readme file). involves unzipping of library jars, it's bit slow, these heavily cached. sbt-pack sbt-pack keeps library jars intact, moves them target/pack directory (as opposed ivy cache live), , makes shell script run them. sbt-native-packager sbt-native-packager similar sbt-pack started sbt committer josh suereth , , maintained highly capable nepomuk seiler (also known muuki88). plugin supports number of formats

so doing program go through every folder in designated folder , if there files inside of thoes folder, read them. the files this: file name: grades mait 5 5 5 kati 3 3 3 vello 4 4 4 so read in each line , 0th element in every line name of student add array. after take grades , calculate median of them. also files in folders named class name. instance math has every math grade in it. now programs job read thoes files , produce output file contains every students name , median in every class , after median of grades. this how output looks right now: nimi: mait keskmine hinne: 5.0 aine: ..\text\students\english\grades nimi: kati keskmine hinne: 3.0 aine: ..\text\students\english\grades nimi: vello keskmine hinne: 4.0 aine: ..\text\students\english\grades nimi: mait keskmine hinne: 1.0 aine: ..\text\students\math\grades nimi: kati keskmine hinne: 2.0 aine: ..\text\students\math\grades it's not in english in form of name:, median; , class name; now problem here th

i'd specify allow rule document update in meteor.js depend on properties of updated document. in update callback, old document, list of changed top-level fields , mongo modifier. there easy way determine how document if updated?     a non-trivial real-life example: i've got party model maxcount integer specifies how many people can fit in party, , people array names of people attending. user can push several names array. i'd allow update made if in resulting document length of array not exceed maxcount . this perfect example of why allow/deny rules in current form insufficient real world problems. there multitude of ways document can updated, , it's impractical check of them tools allow/deny gives you. i'd should use them if permissions like: "the owner of document can whatever wants document". that being said, if really want example above try checking if people.length < maxcount when modifier['$push']['people&

how can that? procedure tfmain.button2click(sender: tobject); begin showmessage('cya!!'); application.terminate; end; is there way able click ''ok'' showmessage , if dont wont able click else in interface? i think you're looking mb_systemmodal flag on messagebox . instead of showmessage , call messagebox directly, this: messagebox(application.handle,'cya!!',pchar(application.title),mb_ok or mb_iconinformation or mb_systemmodal);

i developing android phonegap app 'facebook connect' plugin. this documentation , plugin page have used; phonegap-facebook-plugin after installing plugin, when app launch , trigger fb login function, gets "unfortunatly has stopped" message , crashes. i have installed before without issues. time doesn't work well. i using cordova. 3.3.1-0.1.2 , phonegap. 3.3.0-0.19.6 . i didn't why u mention both cordova , phonegap.. but please check answer! add below config.xml , ensure place config.xml in root folder index.html file: <gap:plugin name="com.phonegap.plugins.facebookconnect"> <param name="app_id" value="..." /> <param name="app_name" value="..." /> </gap:plugin> add below of index.html file , every .html file want access plugin scripts: <script scr="phonegap.js"></script> <script src="cdv-plugin-fb-connect.js">&l

suppose have (fictional) set of projects: foo , bar. both of these projects have sort of multi-configuration option. foo has matrix on axis x takes values in { x1, ..., xn } (so there n builds of foo). bar has matrix on axis y takes values in { y1, ..., ym } (so there m builds of bar). however, bar needs copy artifacts foo. turns out y strictly finer partition n. example, x might take values { windows, linux } , y might { windows_xp, windows_7, debian_testing, fedora } or whatever. is possible bar sort of table lookup work out configuration of foo needs when copies artifacts across? can write shell script spit out mapping, can't work out how invoke when jenkins working out needs copy. at moment, hacky solution have 2 axes on foo, on x , 1 y , , filter out combinations don't make sense. resulting combination filter ridiculous , matrix sparse. yuck. a solution don't parametrise foo on y instead: huge waste of compile time. and, worse, generated artefa

i've 15 levels, , each level consists of 2 rounds . i've find total score finding max score user earned in round1 , round2 , calculate it. likewise same method how many levels played. and, finally, total result calculating scores levels. can please me find total score using mysql..! i tried code: select *, (classifica_score + max2) total from( select ifnull( max(xx1.classifica_score), 0) classifica_score, xx1.classifica_level, xx1.classifica_round, xx1.fb_id, (select ifnull( max(tc1.classifica_score), 0) tab_classifica tc1 tc1.classifica_round = 2 , tc1.fb_id = xx1.fb_id) max2 tab_classifica xx1 xx1.classifica_round=1 group xx1.classifica_level, xx1.classifica_round, xx1.fb_id union select ifnull( max(xx2.classifica_score),0) classifica_score, xx2.classifica_level, xx2.classifica_round, xx2.fb_id, (select ifnull( max(tc2.classifica_score),0) tab_classifica tc2 tc2.classifica_round = 1 , tc2.fb_id = xx2.fb_id ) max1 tab_classifica xx2 xx

i writing minimal find*.cmake openni. find header files wrote find_path(openni_include_path xnos.h) which working expected (openni_include_path has value /usr/include/ni). however, in files have include headers with #include <ni/xnos.h> how can rid of ni prefix, can write #include <xnos.h> the problem first include xncppwrapper.h gets included , file includes again xn*.h headers, without ni prefix. results in compiler error. always have path use find_path match 1 in #include statements. if want #include <ni/xnos.h> should write find_path(openni_include_path ni/xnos.h) if instead want #include <xnos.h> , use find_path(openni_include_path xnos.h) just sure make mind beforehand 1 want use , stick it . mixing several include paths same library sure way unnecessarily overcomplicate build environment.
