the issue having neon instructions believe supported on arm7 architecture. using default compiler (apple llvm 5.0), recognises other neon instructions although not half-float instruction. here code: vcvt.f32.f16, q0, d1 this has compiled on gcc although apple compiler not instruction , gives error: instruction requires: half-float is there compiler flag can give xcode? can't find out how enable half float instructions googling around. thanks! the half-float format not supported on arm v7 implementations. see arm manual here . it's required vfp4, if chip supports that, that's start. in general recommend using run-time detection , dispatching. enable instruction in general, need use 1 of several floating point support options, in general "fp16" keyword, example: -mfpu=neon-fp16 if sure target supports neon. couldn't find of examples llvm either, think compatible gcc options, found in gcc manual .

i've made new log in / register template uses css3 , html, yet had working form, basic, before this. decided make 'form' should this: http://www.script-tutorials.com/css 3-modal-popups/ now, use form handle registration: <!-- popup form #2 --> <a href="#x" class="overlay" id="join_form"></a> <div class="popup"> <h2>sign up</h2> <p> please enter details here. </p> <div> <form action="register.php" action="post"> <label for="username">username</label> <input type="text" id="username" placeholder="max 32 characters" name="username" /> </div> <div> <label for="password">password</label> <input type="password" id="password" placeholder="pas

i have issue pipes in linux. looks space characters lost after piping. running following c++ code #include <iostream> #include <stdio.h> #include <string.h> using namespace std; int main(){ char s[] = "ab cd", c; int n = strlen(s); for(int = 0; i<n && (cin >> c); i++) if(s[i] != c){ printf("wrong @ %d : '%c' != '%c' \n", i, s[i], c); break; } return 0; } from echo "ab cd" | ./checker shell command gives wrong @ 2 : ' ' != 'c' is normal behavior? how avoid losing characters in pipes? the problem isn't pipe, problem cin >> c skips on whitespace. it work if cin >> noskipws >> c or this: std::string q; getline(cin, q); for(i = 0; < n && < q.size(); i++) { if (q[i] != s[i]) ... }

i create matrix has different row sizes i'm not sure start. i have function produces time signatures of 5000 photons. not photons produce meaningful time signatures. function discards signatures. iterate on function 5000 times means column vector have varying sizes on each iteration never more 5000. function photon_fwhm = processfates(string,num) = 1:num fates = 'fates'; str = int2str(i); filename = strcat(fates,str); timestamp = timestamp(filename); if timestamp == 0 continue; end; photon_timestamps(:,i) = timestamp; end; all in have 5000 columns number of rows vary column. i'm not sure solution is. you try using cell arrays. cell arrays may little slower, can job. photon_timestamps{i} = vector; then each element photon_timestamps{i} can of different size. also block if timestamp == 0 continue; end; needs else part right?

i have script lists possible permutations in array, which, admittedly, might used instead of wordlist. if work, it'll impossible not hit unless there limit on attempts. anyway, script takes huge amount of memory, set server on fire. need finding way spread out memory usage, somehow resetting script , continuing left off going file or something, possibly using sessions. have no clue. here's i've got far: <?php ini_set('memory_limit', '-1'); ini_set('max_execution_time', '0'); $possible = "abcdefghi"; $input = "$possible"; function string_getpermutations($prefix, $characters, &$permutations) { if (count($characters) == 1) $permutations[] = $prefix . array_pop($characters); else { ($i = 0; $i < count($characters); $i++) { $tmp = $characters; unset($tmp[$i]); string_getpermutations($prefix . $characters[$i], array_values($tmp), $pe

i want toggle css link using jquery, via single button. catch is, want in target of iframe. so far have following code, insets link fine: $("#custom").click(function() { $("#content").contents().find("head").prepend("<link href=\"../build/css/custom.css\" rel=\"stylesheet\" id=\"custom-css\">"); }); this activated following html: <div class="toggle-custom"> <a target="custom" id="custom" class="btn btn-primary btn-lg">toggle custom style</a> </div> <iframe id="content" src="carousel.html" frameborder="0" scrolling="auto"> </iframe> i know way remove is: $("#content").contents().find("#custom-css").remove(); but how can toggle same button? thanks try var contents = $("#content").contents(); var ccss = contents.find("head")

i'd make commenting thread stackoverflow on each q&a page. issue see how notify each subscriber (questioner, answerers, commenters) of new comment allowing them each ability mark comment read. i see 2 general solutions: make row each subscriber, replicating actual comment in every 1 of these rows. allow field in each row each subscriber mark comment read (eliminating little red circle @ top of page). only have 1 row each comment. subscribers lumped in single field , there have complex queries select , update whether each subscriber has marked comment read. maybe there better way? here's generic schema show 2nd approach answers can have refer to: comments table comment_id user_id question_id comment comment_read 1 1 1 stuff yes=user_id=1, no=user_id=2, no=user_id=3 2 2 1 bad stuff yes=user_id=1, yes=user_id=2, no=user_id=3 3 3 1 worse stuff yes=user

is possible set less variable given value, if hasn't been defined? i can seem find solutions sass. an important remark : turns out need such trick happens xy-problem (as result of misunderstanding less variable semantics). there's no real use-cases want (in less instead always define default value (so exists) overridden @ will). before using trick below, make sure it's not something else want actually . it quite simple (since v1.4.0) if need provide such variable same scope (i.e. global or local) defined: @bar: 41; // comment/uncomment test .define-bar-if-not-defined() {@bar: 42} .define-bar-if-not-defined(); // exposes variable if it's not in scope #using-global-bar { global-bar: @bar; } #using-local-bar { @bar: 43; // comment/uncomment test .define-bar-if-not-defined(); local-bar: @bar; } however method won't work if try use global/parent scope variables used in local scope (and may problem if need generic method when yo
