i trying validate form, , testing event handlers new them. wondering why code loop, in sense moment click on input field messages keeps on showing. have thought of adding boolean stop it, there better way? $(document).ready(function(){ function test() { alert("this keeps showing up!"); } document.formulario_reserva.dni.addeventlistener("focus", test, false); });

what best way enforce per-user quota on data stored in firebase? my users able create documents unique id on following path: /documents/id/contents the id uniquely generated using transaction. id reserved using verification rule ( contents.id == auth.id ) however how prevent user spamming db (by randomly allocating ids themselves)? can have rule counts number of ids allocated user , rejects them if count high? there's no way this. in cases enumerate children allowed exist (child1, child2, etc), , grant read / write each one. won't work large numbers though or ids don't know beforehand. we have plans built features restrict number of allowed children , provide other features enforce quotas on users.

i have product entity , shop entity. a shop can have 0 n products , product can in 1 shop. the product entity table refering shop entity through shop_id table field. when querying products of given shop using doctrine query builder, can this: $products = $this->getdoctrine()->getrepository('mybundle:product') ->createquerybuilder('p') ->where('p.shop = :shop') ->setparameter('shop', $shop) // here pass shop object ->getquery()->getresult(); or this: $products = $this->getdoctrine()->getrepository('mybundle:product') ->createquerybuilder('p') ->where('p.shop = :shopid') ->setparameter('shopid', $shopid) // pass directly shop id ->getquery()->getresult(); and both seem work... i'm wondering: can pass directly entity ids instea

i think basic question concerning java 8 streams, have difficult time thinking of right search terms. asking here. getting java 8, bear me. i wondering how map stream of tokens stream of n-grams (represented arrays of tokens of size n). suppose n = 3, convert following stream {1, 2, 3, 4, 5, 6, 7} to {[1, 2, 3], [2, 3, 4], [3, 4, 5], [4, 5, 6], [5, 6, 7]} how accomplish java 8 streams? should possible compute concurrently, why interested in accomplishing streams (it doesn't matter in order n-arrays processed). sure, old-fashioned for-loops, prefer make use of stream api. such operation not suited stream api. in functional jargon, you're trying called sliding window of size n . scala has built-in sliding() method, there nothing built-in in java stream api. you have rely on using stream on indexes of input list make happen. public static void main(string[] args) { list<integer> list = arrays.aslist(1, 2, 3, 4, 5, 6, 7); list<list<

i build directive time selection 2 blocks. problem catch target event on blocks inside directive template. directive template: <div class='time-picker-container'> <div class='block1' ng-click='show()'>1</div> <div class='block2' ng-show='selectvisible'>2</div> </div> js: scope.selectvisible = false; scope.show = function() { scope.selectvisible = scope.selectvisible ? false : true; } $rootscope.$on('documentclicked', function(inner, target) { //try hide div.block2 if user make click outside block. }); basic idea: when user make click on document, outside div.block2, block disappear. when user click somewere inside div.block2 block stay visible. on run function: angular.element(document).on('click', function(e) { $rootscope.$broadcast('documentclicked', angular.element(e.target)); }); in template, add $event argument ng-click handler

i converting php-mysql application php-odbc application. ie getting database migrated mysql db2. while using mysql used mysql_data_seek function reset recordset pointer, not work odbc connection. tried , checked odbc_fetch_row($recordset,0) resetting recordset, not work. know how reset recordset via odbc connection? according the docs , need pass 1 second parameter instead of 0 . to step through result more once, can call odbc_fetch_row() row_number 1, , continue doing odbc_fetch_row() without row_number review result. however, note if driver doesn't support method, there may not way accomplish task: if driver doesn't support fetching rows number, row_number parameter ignored.

my question simple..but cant manage work out... have run variable selection method in r on 2000 genes using 1000 iterations , in each iteration got combination of genes. count number of times each combination of genes occurs in r. example have # iteration 1 genes[1] "a" "b" "c" # iteration 2 genes[2] "a" "b" # iteration 3 genes[3] "a" "c" # iteration 4 genes [4] "a" "b" and give me "a" "b" "c" 1 "a" "b" 2 "a" "c" 1 i have unlisted list , got number each gene comes interested in combination. tried create table have unequal length each gene vector. in advance. the way think of paste them , use table follows: genes_p <- sapply(my_genes, paste, collapse=";") freq <- as.data.frame(table(genes_p)) # var1 freq # 1 a;b 2 # 2 a;b;c 1 # 3 c 1 the above solution assum

i keep getting segmentation fault , know char pointer. cant figure out why? whiskey* createwhiskey(int a, double p, char* n){ whiskey* whiskey = malloc(sizeof(whiskey)); whiskey->age = a; whiskey->proof = p; whiskey->name = malloc((strlen(n)+1) * sizeof(char)); strcpy(whiskey->name, n); return whiskey; } int main(){ whiskey* burbon; burbon = createwhiskey(12, 90.0, "makersmark"); free(burbon); return 0; } in comment alex (see below) following information added: typedef struct{ int age; double proof; char* name; }whiskey; as discussed in comments program shown fine. however, should add checks avoid problems. like: typedef struct{ int age; double proof; char* name; } whiskey; whiskey* createwhiskey(int a, double p, char* n){ whiskey* whiskey = malloc(sizeof(whiskey)); if (whiskey) { whiskey->age = a; whiskey->proof = p; if (strlen(n) > some_maximum)

i learning karatsuba algorithm fast integer multiplication , wondered, since computers have dedicated hardware built cpus multiplication why algorithm necessary? is large numbers hard multiply, algorithm breaks down simpler steps easier hardware handle, because hardware @ multiplying smaller numbers? all cpu has fixed bit width alu/fpu. for example on i80x86 (pc) alu limited to: i8086+ 16 bit i80386+ 32 bit x64 arch 64 bit allowing compute 16/32/64 bit numbers operands. i80x87 fpu use 80 bit number representations converted from/to ieee float(32bit)/double(64bit) limiting precision. if need compute numbers bigger bit width hw limit then need break down chunks computable on alu/fpu (and handle them digits of number) , combine results final value. alu counting , why cpu's have carry flag , alu support adding , substracting carry. if doing simple +/- add/subs digits lowest (lsw) highest (msw) propagating carry. see: cant make value propagate thr

i've been trying figure out how resize initialized array in ocaml. however, seems while can write function create brand new array elements of old 1 copied on (and slots), function's output cannot assigned existing array. how 1 this? there easy way in use references make happen if not without? here's tiny example: let rec function_that_adds_to_array storage args ... = (* let's function has set of if-else constructs controls does, , let's further 1 of cases leads to: *) let new_array = array.make (array.length storage) ("null", ("null", -2)) in array.blit collection 0 new_array 0 index; (* index controlled function's recursion *) array.set new_array index (obj_name, obj_expr); new_array) (* insert macro @ tail *) ... ;; ### main method ### let storage = array.make 10 ((x : string), (a, b)) in ... while true ... storage = function_that_adds_to_array storage args....; ... a print statement @ end of function_that_a

i did successful docker windows install on 2 windows machines (windows 10 , windows 7 x64 sp1). can perform administration duties of docker hosts through terminal services (rdp) or through powershell remoting. however, docker documentation indicates docker host offers own restful remote api administration. use api. problem in examples given in documentation, client invocations (via curl ) physically on same box docker host. in other words not remote and, unfortunately, steps adapt remote scenario not obvious. for example, consider command taken straight documentation: curl --insecure --cert ~/.docker/cert.pem --key ~/.docker/key.pem https://your_vm_ip:2376/images/json obviously need your_vm_ip proceed. on both of windows boxes type docker-machine ls . discover on both physical windows machines address docker host tcp://192.168.99.100:2376 . oops. can't both have same ip address. virtualbox nat address local vm in both cases. this primary issue. i
