if set socket non-blocking, should recv() if there no new data read? at moment, using , if statement see if received greater -1. seems block somehow if nothing received. code looks like: flags = fcntl(newfd, f_getfl); flags |= o_nonblock; fcntl(newfd, f_setfl, flags); while(1){ ... ... if( (recvbytes = recv(newfd, recvbuf, maxbuflen-1, 0)) > -1) { ... } } according manpage: if no messages available @ socket , o_nonblock not set on socket's file descriptor, recv() shall block until message arrives. if no messages available @ socket , o_nonblock set on socket's file descriptor, recv() shall fail , set errno [eagain] or [ewouldblock].

i want resize webview vertically fit content. how find out best height is? i tried looking @ webframe's frameview, that's size of view it's being displayed in, , [frameview intrinsiccontentsize] returns -1, -1. update: i can this: domnode *bodynode = [[[frame domdocument] getelementsbytagname:@"body"] item:0]; float scrollheight = [[bodynode valueforkey:@"scrollheight"] floatvalue]; ..but result never less height of webview, when content plainly shorter. the answer here: how resize webview according content? the key in comments accepted answer: resize webview small before getting size.

i have find info running unittest helper class' static method. idea getting unique key each test. i thought using testcontext , not sure if possible. exemple [testclass] public void mytestclass { public testcontext testcontext { get; set; } [testmethod] public void mytestmethod() { testcontext.properties.add("mykey", guid.newguid()); //continue.... } } public static class foo { public static getsomething() { //get guid test context. //return base on key } } we storing key on thread thread.setdata , problematic if tested code spawn multiple thread. each thread need same key given unit test. foo.getsomething() not called unittest itself. code calling mock injected unity. edit i'll explain context little bit, because seems confusing. the object created via unity entity framework's context. when running unit tests, context data in structure created foo.getsomething . let's c

i sending smsc example string "[ ]" encodes byte[] in hex "1b3c201b3e" according gsm 7-bit alphabet "1b" character 10 characters , 3c "[" , 3e "]" accordingly won't print print correctly on cellphone prints " < >" because prints "1b" space , "<" = "3c" , ">" = "3e". also, can't print of weird characters "èéùìòÇØøÅå€ÆæßÉ@¤¡ÄÖÑܧ¿äöñüà" works fine greek chars. error or has specific smsc? byte[] correct or not? you need choose 1 data_coding (or encoding scheme) based on kind of characters need use. page 136 of smppv4 protocol spec document shows data codings can use. then example, if choose ucs2 can make msg.getbytes("ucs2") , set datacoding 8 , make ucs2 representable characters shown in phone. i think if need use gsm 7-bit alphabet need set datacoding 1, need gsm 7-bit alphabet encoder, string bytes, think not available i

we trying replace our own aes implementation use standard ios aes implementation (see will our app fips 140-2 compliant if use our own aes algorithm implementation? ). original aes implementation encrypts , decrypts on source data buffer, no new allocation/free. standard ios aes implementation, have malloc memory destination data buffer dynamically encrypt/decrypt data. worried frequent memory allocation , free result in memory fragmentation. current memory allocation size 1k 8k bytes (depending on ios disk sector size, fixed on 1 particular device), should times of 1k. allocation/free mixed memory allocation of other size, worried create lot of memory fragmentation. one way solve use local variable fixed size (really sqlite3 page size). problem page size range 1k 8k (depending on ios disk sector size, not sure if ios device reach 8k though) on different devices, mean have allocate 8k local buffer every time since need assign size @ compile time. or allocate smaller local buffer

how grid system works websites expand full size of browser (no matter how resize) while working 12 grid_ system? for example, take on these websites: http://vevo.com http://xfinitytv.comcast.net http://pinterest.com is there technical name this? why there's no many websites take advantage of full browse size? thanks the "technical name" you're asking called "fluid" layout. in terms of how achieve in bootstrap, answer depends on whether you're using v.2.x or newly released version 3. in version 2.x fluid effect obtained wrapping grid elements in "container-fluid" class. in release 3, "container" class fluid default. (see bootstrap: migrating 2.x 3.0 more.) as why more sites don't use fluid layout in most, that's rather subjective question. i'll comment personal experience (15 years in web design , development)> fluid design doesn't become problem until larger displays, having content s

this how load data // loads entire list of metriclibs. function homectrl($scope, $http, $location) { $scope.data = []; $scope.pagesize = 100; $scope.currentpage = 0; $scope.lastpage = 0; // async $http.get('index.cfm/json/metriclib') .success(function(data) { $scope.data = data; $scope.lastpage = math.floor($scope.data.length/$scope.pagesize); }) .error(function(data) { console.log("data load error"); }) ; $scope.go = function ( path ) { $location.path( path ); }; $scope.numberofpages=function(){ return $scope.lastpage; } } this how show data without pagination (this works) <tr ng-repeat="datum in data | filter:search | limitto:pagesize" class="odd"> this me thing set starting point <tr ng-repeat="datum in data | startfrom:0 | limitto:pagesize" class="odd"> when second 1 get: [19:5

i making app show places near user's current location. when user moves map, map moves user current location, on , on again. so, user can't see annotations on map, because if moves map, map goes current location. this doing right now: - (void)mapview:(mkmapview *)mapview didupdateuserlocation:(mkuserlocation *)userlocation { if (userlocation) { mkcoordinateregion region = mkcoordinateregionmakewithdistance(userlocation.coordinate, 1000, 1000); mkcoordinateregion regiondelmapa = [self.mapa regionthatfits:region]; if(isnan(regiondelmapa.center.latitude)) { nslog(@"bad region..."); }else { [self.mapa setregion:regiondelmapa animated:yes]; } } } i have tried other answers here, nothing happens. not desired behavior, how can stop updating user's current location? [self.mapa setregion:regiondelmapa animated:yes]; that line sets map region. you're executing code every time update, reseting area map co
