if user logs in , passes security checks (username, password, 2fa... whatever) , hypothetical php login system like: session_start(); $_session['logged_in_userid'] = 1; how safe rely on existence of $_session value 'logged_in_userid' proof person did pass full security check? not very, i'm thinking. if xss determine phpsessid, , manually add own local cookies. not going automatically assumed logged in when visit same system? if - resolution record, @ login time, in _session the: remote_addr, http_user_agent , x_forwarded_for , compare @ each request time not _session logged_in_userid _session remote_addr etc etc found in current _server vars? or flawed also? it secure but need stuff make sure can't 'hijack' session xss example mentioned: static protected function preventhijacking() { if(!isset($_session['ipaddress']) || !isset($_session['useragent'])) return false; if ($_session['ipaddress

to on safe side , see fruits of hard work, features of data needs correctly formatted? i have dataset , template , manually tagged ner. as far training crf++ concerned, testing generated model yields 0% correct results. results same using wapiti. question, should template file modified? or imperative add pos tags in training dataset well. additionally, if model should discount word casing while labeling, should training dataset reflect in entirety, lower casing enforced. not affect sentences derive meaning uppercasing. bit unclear in respect. ps - targeting model like, http://cliff.mediameter.org/ , ner labeled irrespective of casing. can't use model. the training data small ( hardly 47 sentences ) , format incorrect because sentences end empty lines, yours end space-tab-space, might make crf++ learn whole file single sentence. try http://paste.ubuntu.com/24537692/ also, share test data?

i have question these 2 algorithms: this works normally: node* deletetree(node* root) { if(root != null) { deletetree(root->left); deletetree(root->right); deallocatenode(root); } return root=null; } this nope: void deletetree(node* root) { if(root != null) { deletetree(root->left); deletetree(root->right); deallocatenode(root); } root=null; } why? need set root null node pointer after delete of bst not point memory not allocated. prefer second algorithm because recall of function more intuitive. theoretically, 2 algorithms equivalent if use second algorithm , try print bst, program goes in loop. when have node *root , assign node = null won't affect value in exterior. if want modify pointer value, you'll have pass double pointer. something like: void deletetree(node** root) { if(*root != null) { deletetree(&((*root)->left)); deletetree(&(

i'm having issue passing htmliframeelement object parent site iframe (located on different domain) using postmessage method. this code tried: var frame = document.getelementbyid('myhtmliframeelement'); frame = json.parse(json.stringify(frame)); event.source.postmessage(frame, "*"); unfortunately, json.parse / json.stringify not seem right way of handling htmliframeelement object. can please advise how pass through htmliframeelement object correctly? parsing dom elements json not useful far know. since postmessage() part of window object, try using window object of frame, found under contentwindow property of iframe. so try like: var frame = document.getelementbyid('myhtmliframeelement'); frame.contentwindow.postmessage( "stuffyouwanttosendtotheiframe", '*' ); and in script inside iframe: window.addeventlistener('message', function( event ) { // handle message });

hi using php learn algorithms, wanted convert psuedocode php, for = 1 n − 1 minval = a[i] minindex = j = n if (a[j] < minval) minval = a[j] minindex = j exchange a[i] , a[minindex] this corresponding code in php $a = array(1, 4, 2, 3, 70, 10, 7 ); $n = sizeof($a); ($i = 0; $i == $n - 1; $i++){ ($j = $i + 1; $j == $n; $j++){ if ($a[$i] > $a[$j]){ $temp = $a[$j]; $a[$j] = $a[$i]; $a[$i] = $temp; } } } print_r($a); print_r outputting array original order, why algorithms doents reorder array ? you should check for loops : for ($i = 0; $i == $n - 1; $i++){ ($j = $i + 1; $j == $n; $j++){ should for ($i = 0; $i < $n - 1; $i++){ ($j = $i + 1; $j < $n; $j++){ as second argument in for requirement continue loop.

this question has answer here: how return response asynchronous call? 21 answers i feel i'm overlooking here, trying write function returns synchronous value, internally needs data can fetched async: // gets asynchronously const getvalueasync = promise.resolve('value') // needs return value synchronously const returnsyncvalue = () => { // needs async data here getvalueasync // modify // return result sync } // work: const value = returnsyncvalue() i'm using latest version of node. there way of achieving without changing returnsyncvalue's implementation (i.e. making async well)? short answer: no long answer: you can't because when const value = returnsyncvalue() , haven't gotten async value yet. therefore there no value assign.

i want calculations using text files , user input, want ask user number minus, want number text file used , minus number user gives , save sum in same text file original number was. problem don't know how this, example have number 13 on text file, user enters 4 sum 9, want 9 saved in same text file number 13 don't know how this. tried using file.write function no success. i not quite sure how compare values of text file in if/else statement or while statements. this have done far, apologize might not make sense, need work want work. number = int(input('please enter number minus')) d = open("numberfile.txt","r+") d.write(int(d.read()) - int(number)) d.close() whenever run says write argument must in str not int, when change str says operation - not supported. you should open files with since handles outmatic file closing etc. you should try if input of user , of input file convertable int . import sys input = inp

when compiling gcc optimization. values of variables optimized out. know gcc pass optimizes variables value out, can disable such pass keep variables unoptimized? thanks. your question quite vague, should take @ flags such -fssa-backprop . according gcc documentation : propagate information uses of value definition chain in order simplify definitions. example, pass strips sign operations if sign of value never matters. this optimisation turned on @ level -o1 (and higher levels of optimisation well).

i want add multiple columns pandas dataframe , set them equal existing column. there simple way of doing this? in r do: df <- data.frame(a=1:5) df[c('b','c')] <- df$a df b c 1 1 1 1 2 2 2 2 3 3 3 3 4 4 4 4 5 5 5 5 in pandas results in keyerror: "['b' 'c'] not in index" : df = pd.dataframe({'a': np.arange(1,6)}) df[['b','c']] = df.a you can use .assign() method: in [31]: df.assign(b=df['a'], c=df['a']) out[31]: b c 0 1 1 1 1 2 2 2 2 3 3 3 3 4 4 4 4 5 5 5 or little bit more creative approach: in [41]: cols = list('bcdefg') in [42]: df.assign(**{col:df['a'] col in cols}) out[42]: b c d e f g 0 1 1 1 1 1 1 1 1 2 2 2 2 2 2 2 2 3 3 3 3 3 3 3 3 4 4 4 4 4 4 4 4 5 5 5 5 5 5 5 another solution: in [60]: pd.dataframe(np.repeat(df.values, len(cols)+1, axis=1), columns=['a']+cols) out[60]:

just strange thing have 3 pages in php define global variables define() uploaded in xampp server. the main page has required pages // defined password , username costants; require_once('config.php'); // defined other new constants , use password , username constant. require_once('http_post.php'); config.php , http_post.php has no reference (required) each others. i asking myself how http_post can take password , username defined in config.php without reference, in 1 xampp installation works all, htt_post.php can retrieve username , password variable (localhost) config when upload server xampp (no more localhost me) http_post.php cannot see username , password in config.php. how possible? changed? particular behaviour of localhost? 2 php pages referred main page in way connected? thx lot use localstorage or cookies. in php can have use this: echo "<script>localstorage.username = " . $username . "</script>"

i given data file included mass , (x,y,z) position of point. want take data given , output file using multidimensional array. don't know how take scanned data , use in array, however. i have data stored follows: for(i = 0; < n; i++) //scan in file data { fscanf(fpin, "%d %d %d %d", &array_x[i], &array_y[i], &array_z[i], &array_mass[i]); } i tried setting array [][4] since number of rows dependent on number of data points given (and instructions write array work number of data points, not given) , there 4 columns (one x, y, z, , mass respectively). then tried setting as: for(i = 0; < n; i++) { array_out[i][4] = { {array_x[i]}, {array_y[i]}, {array_z[i]}, {array_mass[i]} }; } and printing as: for(i = 0; < n; i++) for(j = 0; j < n; j++) fprintf(fpout, "%d %d %d %d", array[i][j]); but doesn't work. do know how many elements need read? if do, can allocate array hold them. if not n
