i have retrieved ip, subnet , broadcast using ioctl() system call. can me find out whether client static or dhcp?? asking in general , using system call. client instead of interface. the interface has nothing dhcp. can configured have particular ip address, gateway, etc. that's all. configuration, however, can done smart little program called dhcp client :) need find out (i mean, program) has configured interface. update: for example, under majority of linux distributions may a ps aux | grep 'dhcpcd .* eth0' if gives result /sbin/dhcpcd --netconfig -l -e -hhh -c /etc/sysconfig/network/scripts/dhcpcd-hook -t 0 -h somehostname eth0 you can eth0 configured dhcp

i have code loads list mvc controller. i load data with $scope.loaddata = function () { $scope.promise = myhttp = $http.get("forms"); myhttp.success(function (response) { $scope.rows = response; this works fine, data loads , can see data on html page. but, if reload code, eg run $scope.loaddata again, fails in ie. works in chrome, ff fails in ie , spartan (tested on non windows 10 same issue) the headers like cache-control: private, s-maxage=0 the mvc controller has authorise attribute hence s-maxage=0, prevents proxy caching. i have tried $scope.promise = myhttp = $http.get("forms"); when fiddle, dont see request going server code fired. if nav new page , nav reload fresh data expect. when reload done $http thanks edit post works, eg $scope.promise = myhttp = $http.post("forms");

it possible put arrays custom length anywhere in struct in c, in case additional malloc calls required. compilers allow having vlas anywhere in struct, not standard compliant. decided emulate vlas within struct standard c. i in situation have maximum performance. code in c automatically generated, readability or style not important in case. there structs many custom size array members in between static size members. below simple form of such structs. struct old_a { int n_refs; void **refs; int count; }; struct old_a *old_a_new(int n_refs, int count) { struct old_a *p_a = malloc(sizeof(struct old_a)); p_a->n_refs = n_refs; p_a->refs = malloc(n_refs * sizeof(void *)); p_a->count = count; return p_a; } #define old_a_delete(p_a) {\ free(p_a->refs);\ free(p_a);\ } while (0) the additional malloc call refs can avoided follows. #define a_get_n_refs(p_a) *(int *)p_a #define a_set_n_refs(p_a, rval) *(int *)p_a = rval #define

when using jquery in conjunction content management system, find myself writing snippets of code such $(document).ready(function() { var thishtml = $('#some-element')[0].outerhtml; $('#some-element').remove(); $('#hmpg-btm-box-holder').prepend(thishtml); }); does jquery have functionality accomplish in more compact fashion? this should suffice: $(document).ready(function() { $('#hmpg-btm-box-holder').prepend($('#some-element')); }); i'd avoid using outerhtml whenever possible (and preferably innerhtml also, unless e.g. receive html trusted server via ajax , want include in document). converting element element string (html) representation , element can cause unwanted effects removing event handlers attached it.

(apart using pipes). here actual code: for(i=1; i<=10; i++) { fork(); printf("the process pid=%d\n", getpid()); } there 1 byte exit status of process. therefore, cannot count higher 255 via process exit codes. furthermore, quirk of specific algorithm tried happens produce maximum possible exit status (to parent process adds 1 256 ). exit() function uses least significant 8 bits of argument (and returning x main() has same effect calling exit(x) ). to count higher, need different approach. establish counter in shared memory, , have each child process increment (with appropriate synchronization). runs cleanly, shared memory n

i supposed generating randomly ordered alphabet. know of shuffle methods , things fisher-yates shuffle algorithm, tried never work. had "reference" array of alphabet in regular order. have loop each 26 spaces. generate random int between 0 , 25(for index in reference array). then, check if array has char in it(it must unique) if unique, add array. still has duplicates though. here's code: public static final char[] alphabet = {'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z', ' '}; public static char[] ciphergenerator(){ char[] cipheralpha = new char[26]; for(int index = 0; index < 26; index++){

i have dictionary (concurrent) used map 1 object id another. getting value id based on input key rather expensive, want persist dictionary in server cache. i have first-blush attempt @ method this, "feels" there better way it: private string getitem(string cachekey, string itemkey) { string sfaccountid = null; concurrentdictionary<string, string> sfaccountmap = context.cache[cachekey] concurrentdictionary<string, string>; if(sfaccountmap == null) { lock(cachelock) { sfaccountmap = context.cache[cachekey] concurrentdictionary<string, string>; if(sfaccountmap == null) { sfaccountmap = new concurrentdictionary<string, string>(); sfaccountid = expensivemethodreturnsstring(); if(!string.isnullorempty(sfaccountid)) { sfaccountmap.tryadd(itemkey, sfaccountid); }

i have 3 scripts written in python. an initialization script a script contains custom data structure class a monitoring script. the initialization script starts first. creates object of custom data structure , starts monitoring script. monitoring script @ points send values fill object created in initialization script. so, there global data object created initialization script. monitoring script add data object. data object buffer contains tasks executed later. how accomplish task of adding data data object monitor script? example scripts: initialization script: import monitorscript import customdatastructure # creates object customdatastructure # starts monitor script custom data structure: class mydata(object): def __init__(self, arg1 = none, arg2 = none): self.arg1 = arg1 self.arg2 = arg2 class mydata2(mydata): def __init__(self): self.queue = [] self.length = 0 def addtask(self, data): # adds task exe
