i trying started using jenetics java library genetic algorithms , there don't understand ga limited backgroud; as understand ga generates population of arrays of m elements, each array potential solution evaluated, once evaluated, potential solutions sorted , best chosen create new population, etc. find solution (genotype) in jenetics list of arrays each array understand potential solution, each array can have different lengths , don't understand why use structure instead of vector of genes. see page 6 of the manual , section 3.1.3. if possible know why this. hope have made question clear enough. the "array" of potential solutions (phenotpyes/genotypes) collected in population. genotype represents 1 possible solution. don't confused 2-dimensional structure of genotype, should give additional flexibility modeling more complicated problems. geneotype still represents 1 possible solution , 1 individual of population. a genotype classical binary ...

i have uitextview become first responder on viewload. want change position of cursor of uitextview @ position in x first 2 line only. maybe use uitextkit ( a tutorial ). for example have rounded text can use like: uibezierpath* exclusionpath = [uibezierpath bezierpathwithovalinrect:yourtextview.bounds]; exclusionpath = [exclusionpath bezierpathbyreversingpath]; yourtextview.textcontainer.exclusionpaths = @[exclusionpath];

i've been trying generate longest possible palindrome included in given string, in java. but, ended in errors. let me provide sample input , output may . input: this sample string testing output: ttissaepeassitt it great if solve me this!! thank you!! you use recursive algorithm: public string findpalindrom(string input){ string palindrom = ""; for(int i=0; i<input.length(); i++){ char c = input.charat(i); // explore string beginning, char char for(int j=input.length()-1; j>i; j--){ // explore string end, char char if(input.charat(j)==c){ // found letter palindrom string newpalindrom = c + findpalindrom(input.substring(i+1, j)) + c; if(newpalindrom.length() > palindrom.length()) palindrom = newpalindrom; } } } if(palindrom.length()==0 && input.length()>0) palindrom += input.charat(0); // manage case palindrom possible single char. ...

in java library thread pool implementations, shutting down pool means: -stop accepting new tasks -previously submitted tasks executed -all pool threads terminated regarding last point, how stop pool thread potentially try take new task, after has been stopped? my threads (in java pseudo code): public void run() { while(!isstopped) { task task = taskqueue.take(); //line1 task.run(); //line2 } } and have method stop: public synchronized void stop(){ isstopped = true; this.interrupt(); } in thread pool class, have method stop: public synchronized void shutdown(){ this.isshutdown = true; //to stop whole pool for(poolthread thread : threads) thread.stop(); } the point is, if thread reaches line 1, isstopped false, @ same moment set true pool class. how remember should stop thread again? calling interrupt suffice? send shutdown messages through task queue: static task stop = // special value public void run() { while (true) { ...

in previous question , asked syncing data davical server. ended concluding there bug on davical when querying caldav server invalid sync token, server should return error but, instead, returns whole set of events on server. so started looking alternative caldav server. use sabredav. followed handy tutorial here . on there says: caveats note server free 'forget' sync-tokens have been issued. in case may needed full-sync again. in case supplied sync-token not recognized server, http error emitted. sabredav emits 403. that looks promising : need ! so getting sync-token http://sabre.io/ns/sync/15 . i submit report query follows (maybe that's things wrong?!) string synctoken = "http://sabre.io/ns/sync/15"; string body = " <d:sync-collection xmlns:d=\"dav:\"> " + " <d:sync-token>" + synctoken + "</d:sync-token> " + " <d:sync-level>1<...

in definitive guide of hadoop mentioned that: "sometimes locality constraint cannot met, in case either no allocation made or, optionally, constraint can loosened. example, if specific node requested not possible start container on (because other containers running on it), yarn try start container on node in same rack, or, if that’s not possible, on node in cluster." i not able this, because if application manager needs container on particular node block resides , in case if rm not able create container on particular node requested due unavailability, may create container on node according above sentence, how serve purpose of localization?

i found unusual behavior of std::default . if create nested structure default setters , try create highest level struct default parameters, causes stack overflow. this code compiles, when try run throws thread '<main>' has overflowed stack : use std::default; pub struct { x: i32 } impl default { fn default() -> { { ..default::default() } } } fn main() { let test = { ..default::default() }; } but if set defaults of inherited props, works: use std::default; pub struct { x: i32 } impl default { fn default() -> { { x: 0 } } } fn main() { let test = { ..default::default() }; } is known issue , should post rust issue tracker? compiler version rustc 1.2.0-nightly (0250ff9a5 2015-06-17) . of course causes stack overflow. to make clearer, let's change example little: pub struct { x: i32, y: i32, } impl default { fn default() -> { { x: 1, ..default::default() } } ...

so have image (png file) want scaled @ say, 90%, relative webpage. however, png file big, , when scaled, not take several seconds load, eats ram (my computer has given me warnings low on memory). not need picture quality in instance, how let image render less quality (to speed load time) while preserving scaling , not altering original file? ~ you scale image proportionally html , css browser still load whole image memory. need use photo editing software change resolution of image , image format jpeg, has better compression algorithm png image format. html : <div class="img_resz"> <img src="img.jpg"> </div> css : .img_resz img { width: 90%; }

i ran command sudo lsof -i -n -p | grep tcp , wondering if more clarification on output. specifically, in image: why have ip:port pointing ip:port , @ label 'established'? confused on means exactly. established means tcp connection has completed 3-way handshake.
