i trying write code simple server, receives messages client. connection succesful once server connects client messages not displayed on screen. after close connection client side, server receives messages in 1 go. i need receive messages line line because each line needs de processed individually , in real time (i using hmm driver's actions recognition). could tell me doing wrong? thanko much. public static void main(string args[]) { serversocket my_server = null; string received_message; dataoutputstream output = null; socket socket_connected = null; try { my_server = new serversocket(9090); } catch (ioexception excepcion) { system.out.println(excepcion); } try { socket_connected = my_server.accept(); bufferedreader entrada = null; while (socket_connected.isconnected() == true){ entrada = new bufferedreader(new inputstreamreader(socket_connected.getinputstream()));

i've been thinking how test particular functions used other functions within same file. for example, have 2 functions within 1 file: // validators.js export const required = ...; export const containsuppercase = ...; export const containsnumber = ...; export const password = (val) => [required, containsuppercase, containsnumber].every(f => f(val)); so clearly, password validator depends on required , containsuppercase , containsnumber functions. if wanted stub out, tests didn't have care functions or how validate. this simple, silly example, i've ran same problem more complex scenarios. for example, if try sinon, might try doing this: import * validators './validators'; sinon.stub(validators, 'required').returns(false); sinon.stub(validators, 'containsuppercase').returns(true); sinon.stub(validators, 'containsnumber').returns(true); // test expect(validators.password('notimportant')).tobe(false); i tried d

first, sorry bad english. follow question, in bowyer-watson algorithm, must find super-triangular surround points. how can calculate coordinator (x,y) of 3 verticles of super-triangular ? have fomular ? much. i don't have proof first comes mind doing getting convex hull of set of points 1. convex hull of group of points. 2. initialize variable smallest = infinity. 3. each point p in convex hull following: find point farthest away p call q. set n1 = point left of p (counter-clockwise along convex hull). n2 = point right of p (clockwise along convex hull). l1 = line intersects q , perpendicular line pq. l2 = line intersects p , n1. l3 = line intersects p , n2. = area of triangle thats formed intersections of l1,l2,l3. if < smallest, set smallest = a. 4. return smallest this, of course, returns number isn't helpful instead create triangle class class triangle{ point p1; po

i m using materialized css , works me. when added more dynamic behaviour app, ex when m pre-populating form values , appending them layout, here photo of that: that happens when preset value form on/prior page load (because form html generated server side). however if click quantity field quantity go it's place , stay there. how make stays when pre-populate form value? there class need add (label or input) or javascript or can put out there. if want pre-fill text inputs, use materialize.updatetextfield(); docs says

this might little opinion based, important question. should use promises async operations? if have api, likely, full stack of functions in there should use promises. if make business logic functions, should return promise. wonder if good, make return promise. mean, i'm calling functions inside while loop, each of them returns promise (the functions chained). slower use promises inside function? idea in stack combine promises , regular return values? need learn this, please don't close if function (sometimes) asynchronous, needs return promise. if function never asynchronous, there's no reason return promise, , should avoid it. keep simple , synchronous.

i confused following initialization var in = none: option[fileinputstream] however know that var varname : type = _ // default value initialization var varname : type = somevalue // other default intitalization but var in = none: option[fileinputstream] please thanks // [name] = [value] : [type] var in = none : option[fileinputstream] // can equivalently written as: var in: option[fileinputstream] = none this creates variable of type option[fileinputstream] , initial value none . learn more scala's option type, see http://www.scala-lang.org/api/current/#scala.option

in git, can refer commit before head using shorthand head~, , 2 before using head~2, etc. i have repository has merge commit following: a----b-------------f \ / c----d----e head = f, head~ points b, , head~2 points a. merge commit this, there shorthand point e? yes; ~ specifies generation, but can use ^ specify parent number , in case of merge. git show head^2 will show 2nd parent. (the distinction subtle since without numeric argument both ~ , ^ show same thing, first parent of head . because both ~ , ^ default 1 without numeric parameter. show first parent (by depth) , first parent (by breadth) of course same.)
