Resize an image along rows only or columns only in matlab -

i'm writing function in matlab zoom or shrink image using bicubic interpolation. however, function resizes image along both rows , columns. if want enlarge image along rows only, or along columns only? code far

function pic_new = zoom_image(pic, zoom_value) actualsize = size(pic); newsize = max(floor(zoom_value.*actualsize(1:2)),1); newx = ((1:newsize(2))-0.5)./zoom_value+0.5; %# new image pixel x coordinates newy = ((1:newsize(1))-0.5)./zoom_value+0.5; oldclass = class(pic); %# original image type pic = double(pic); %# convert image double precision interpolation if numel(actualsize) == 2 pic_new = interp2(pic,newx,newy(:),'cubic'); end pic_new = cast(pic_new,oldclass); end

updated: able resize image both along rows , columns. however, doesn't work right

this original image: https://imagizer.imageshack.us/v2/895x383q90/r/903/4jm76i.png

this image after beingness enlarge 2.5 along rows , shrunk 1.3 along columns: https://imagizer.imageshack.us/v2/323x465q90/r/673/ehiaob.png

why there such black box in result image?

updated 2: how did: in command window type

>> img = imread('pic.pgm'); >> newimage = zoom_image(img, 2.5, 1/1.3); >> imshow(newimage)

try editing function have separate zoom rows , columns, la

function pic_new = zoomfunc(pic, zoom_valuex, zoom_valuey) actualsize = size(pic); newsize = max(floor([zoom_valuey zoom_valuex].*actualsize(1:2)),1); newx = ((1:newsize(2))-0.5)./zoom_valuex+0.5; %# new image pixel x coordinates newy = ((1:newsize(1))-0.5)./zoom_valuey+0.5; oldclass = class(pic); %# original image type pic = double(pic); %# convert image double precision interpolation if numel(actualsize) == 2 pic_new = interp2(pic,newx,newy(:),'cubic'); end pic_new = cast(pic_new,oldclass); end

xaml - Button and .resw idea Windows Phone 8.1 -

i have button , want content loaded name .resw file. know can alter in page class or in class possible in xaml default option?

my button:

<button content="" horizontalalignment="left" margin="84,480,0,0" verticalalignment="top" width="220" height="42" foreground="#ff0e0e0e"/>

thanks in advance!

you can set x:uid attribute string in resw file.

<button x:uid="sendbutton" />

the key entry in resw file should this:

sendbutton.content

you can add together path resource file in case have multiple files

<button x:uid="/forms/sendbutton"/>

the i18n scheme introduced winrt totally flexible. suggest reading next article more details:

c++ - avoiding busy wait with boost::asio poll -

c++ - avoiding busy wait with boost::asio poll -

i'm writing service on linux uses boost::asio::io_service io_service::poll in while loop. busy wait loop, e.g. wastes cpu cycles.

void application::run() { seek { std::cout << "tcpserver starting..\n"; _tcpserver.reset( new tcpserver(_io_service, boost::ref(_spstate)) ); // _io_service.run(); while( ! _spstate->quitsignalled() ) { _io_service.poll(); } std::cerr << "quit signalled, tcpserver stopping.. :/" << std::endl; } catch(std::exception & e) { std::cout << e.what() << "\n"; } }

i utilize poll instead of run check if thread in service has signalled service shutdown.

is there way of achieving without using poll in busy wait loop ?

the service uses async io on single thread, , other threads info processing.

i've added sleep between iterations of loop seems cut down waste of cpu time, hoping there might more efficient way?

void application::run() { using boost::this_thread::sleep_for; static const boost::chrono::milliseconds napmsecs( 50 ); seek { std::cout << "tcpserver starting..\n"; _tcpserver.reset( new tcpserver(_io_service, boost::ref(_spstate)) ); // _io_service.run(); while( ! _spstate->quitsignalled() ) { _io_service.poll(); boost::this_thread::sleep_for( napmsecs ); } std::cerr << "quit signalled, tcpserver stopping.. :/" << std::endl; } catch(std::exception & e) { std::cout << e.what() << "\n"; } }

i'd say, take advantage of fact boost::asio::io_service threadsafe default, , do

iosvc.run();

and signal service shutdown on "another thread in service" would:

iosvc.stop();

remember iosvc.reset() before phone call {run,poll}[_one] again, per documentation.

of course of study can utilize other means signal actual logical workers end, that's independent unrelated boost asio

it seems output comes this line in travic-ci, setting paranoid_mode false in .travis.yml not work.

how enable sudo access?

ps: using private repo.

edit: next .travis.yml fail due sudo: must setuid root when running sudo apt-get update -qq

language: python python: - "3.4" before_install: - sudo apt-get update -qq script: - nosetests

setting sudo: true and/or paranoid_mode: false not work.

sudo access turned off on our docker based architecture, used in 2 contexts:

repositories opt in using sudo: true in .travis.yml file (it additionally needs turned on on our side) on our educational programme (see http://education.travis-ci.com)

builds running on our docker based architecture cannot allowed sudo access due security concerns in lxc/docker layer. hope fixed in near future, unfortunately issue out of our own hands.

we working on improving firefox addon, uses sudo itself, shouldn't. we'll post on our blog 1 time has happened.

then in history view, first time select commit, right click , popup menu shows grayed out "add factory". sec time, right click , goes away.

i appreciate help .. thanks!

you need utilize org.eclipse.ui.commands extension point define command id.

also note command in menucontribution not have defaulthandler parameter.

so like:

may know why typetag doesnt have method runtimeclass

many in advance

assuming typetag comes scala.reflect.runtime.universe, can class this:

def runtimeclass(tag: typetag) = tag.mirror.runtimeclass(tag.tpe)

it doesn't have method because not typetags runtime universe.

javascript - How do browsers render contents of a canvas element -

javascript - How do browsers render contents of a canvas element -

how browser render contents of html canvas? things context.lineto(x, y). there must component converts function calls pixel data. want know if there way pixel info without rendering somewhere.

i want know if can run sort of stand lone javascript engines (v8) , pass javascript code , pixel info output.

what want know if there way pixel info without rendering somewhere.

natively no, there no way pixel info besides using canvas (technically bitmap) rasterize vector info (paths) in browser.

the browsers typically utilize underlying graphic core scheme (ie. directx etc.) rasterization. have no access through browser (nor on top of v8/node.js unless modify it). sub-system handle rasterizing of lines, circles, arcs , ellipses pixels, fill polygons , forth, not building array of point positions simply "walking" slope (put simple of course of study - fill uses different approach though based on line scanning).

for lines means current pixel illustration registered temporary relative previous one, circle/ellipses pixel typically in add-on mirrored here , there. in essence there no registration of absolute or relative pixel positions can extracted after rasterization took place.

if after array positions of each pixel need implement own solution of algorithm. unless need special reason cannot see why not utilize canvas much faster you, or work in vector space directly, rasterize them when needed.

you can utilize javascript implement using various line algorithms , have out there. see marke's first-class reply starter. did retro-canvas while can have @ see algorithms used in javascript. optimized well.

in add-on need implement 2d matrix rotation, scaling , translation if want flexibility/compatibility of canvas.

one thing need aware of though approach eliminate anti-aliasing of import smooth looking result. you'll have add together on top if need (you seek sync internal lines drawn on canvas need exact same @ stage can problem linux, mac, windows etc. uses different graphic sub-systems perchance minor variations in result) , require register additional pixels different colors/alpha values.

some resources:

bresenham line , circle algorithm efla line algorithm bresenham ellipse algorithm polygon fill algorithm

these basic building blocks typical polygonal shape (an arc part of circle didn't include this, there exists optimized approaches out there).

you can in add-on utilize catmull/rom , cardinal splines bezier typically implemented 2. order (quadratic, 1 command point) , 3. order (two command points), if want ability create smoother shapes, font outlines , forth.

another possible approach draw shapes on off-screen canvas in white color on black or transparent background, scan each line , set each pixel find it's position , relative color (to alpha) in array. however, not give continuous lines, each pixel's position whatever part of...

c++ - Avoiding redeclaration for header to source file -

c++ - Avoiding redeclaration for header to source file -

let's have 2 files foo.h , foo.cpp

foo.h

class foo { public: foo(); ~foo(); private: /* fellow member functions */ static void dothis(); /* fellow member variables */ static int x; protected: };

foo.cpp

#include "foo.h" int foo::x; void foo::dothis() { x++; }

can avoid hassle of having declare each variable in foo.cpp again? if removed line int foo::x; linker error unresolved external symbol.

is there way of doing without having type line each variable i'm planning use?

you need re-declare static variables. if create variable in class definition without making them static, can leave them there. example:

foo.h

#ifndef _foo_h_ #define _foo_h_ class foo{ private: static int i; //static variable shared among instances int o; //non-static variable remains unique among instances public: foo(); //consructor }; #endif

foo.cpp

int foo::i = 0; //only static variables can initialized when in class //no definition required non-statics foo::foo(){ //constructor code here = 0; };

the #ifndef block prevents header accidentally beingness included multiple times same source file. in case header included in header, which, if these blocks not present, result in infinite include loop , forcefulness compiler quit when counts include depth that's high.

javafx - Starting multiple animations at the same time -

javafx - Starting multiple animations at the same time -

i'm trying start transition in each box of every row, successive boxes (left right) starting own transitions before previous ones finish. looked @ sequentialtransition, seems imply transitions started 1 after after previous 1 finishes.

i'm thinking need utilize paralleltransition each row, how can go doing this?

i noticed constructor paralleltransition(animation... children); possible phone call constructor 1 time animations, given how i'm instantiating each animation separately?

gridpane gp; ... (int i=0;i<gp.getrowconstraints().size();i++) { timeline tl = new timeline(); tl.setcyclecount(animation.indefinite); tl.setdelay(duration.millis((math.random() * 2500) + 500)); (int j=0;j<gp.getcolumnconstraints().size();j++) { tile t = new tile(); tl.getkeyframes().addall( new keyframe(duration.zero, new keyvalue(t.huemultiplier, 15)), new keyframe(duration.millis(5000), new keyvalue(t.huemultiplier, 1)) ); gp.add(t, j, i); } ... }

animation not start until phone call play() method of it. creating them separately in different places adding paralleltransition valid.

paralleltransition pt = new paralleltransition(); ... for(...) { timeline tl = new timeline(); ... pt.getchildren().add(tl); } ... pt.play();

python - Elasticsearch full-text autocomplete -

python - Elasticsearch full-text autocomplete -

i'm using elasticsearch through python requests library. i've set analysers so:

"analysis" : { "analyzer": { "my_basic_search": { "type": "standard", "stopwords": [] }, "my_autocomplete": { "type": "custom", "tokenizer": "keyword", "filter": ["lowercase", "autocomplete"] } }, "filter": { "autocomplete": { "type": "edge_ngram", "min_gram": 1, "max_gram": 20, } } }

i've got list of artists i'd search using autocomplete: current test case 'bill w', should match 'bill withers' etc - artist mapping looks (this output of get http://localhost:9200/my_index/artist/_mapping):

{ "my_index" : { "mappings" : { "artist" : { "properties" : { "clean_artist_name" : { "type" : "string", "analyzer" : "my_basic_search", "fields" : { "autocomplete" : { "type" : "string", "index_analyzer" : "my_autocomplete", "search_analyzer" : "my_basic_search" } } }, "submitted_date" : { "type" : "date", "format" : "basic_date_time" }, "total_count" : { "type" : "integer" } } } } } }

...and run query autocomplete:

"query": { "function_score": { "query": { "bool": { "must" : { "match": { "clean_artist_name.autocomplete": "bill w" } }, "should" : { "match": { "clean_artist_name": "bill w" } }, } }, "functions": [ { "script_score": { "script": "artist-score" } } ] } }

this seems match artists contain either 'bill' or 'w' 'bill withers': wanted match artists contain exact string. analyser seems working fine, here output of http://localhost:9200/my_index/_analyze?analyzer=my_autocomplete&text=bill%20w:

{ "tokens" : [ { "token" : "b", "start_offset" : 0, "end_offset" : 6, "type" : "word", "position" : 1 }, { "token" : "bi", "start_offset" : 0, "end_offset" : 6, "type" : "word", "position" : 1 }, { "token" : "bil", "start_offset" : 0, "end_offset" : 6, "type" : "word", "position" : 1 }, { "token" : "bill", "start_offset" : 0, "end_offset" : 6, "type" : "word", "position" : 1 }, { "token" : "bill ", "start_offset" : 0, "end_offset" : 6, "type" : "word", "position" : 1 }, { "token" : "bill w", "start_offset" : 0, "end_offset" : 6, "type" : "word", "position" : 1 } ] }

so why not excluding matches 'bill' or 'w' in there? there in query allowing results match my_basic_search analyser?

i believe need "term" filter instead of "match" 1 "must". have split artist names in ngrams searching text should match 1 of ngrams. happen need "term" match ngrams:

"query": { "function_score": { "query": { "bool": { "must" : { "term": { "clean_artist_name.autocomplete": "bill w" } }, "should" : { "match": { "clean_artist_name": "bill w" } }, } }, "functions": [ { "script_score": { "script": "artist-score" } } ] } }

ios - What's causing the massive changes in autorotation in 8.1 compared to 8.0.2? -

ios - What's causing the massive changes in autorotation in 8.1 compared to 8.0.2? -

i'm coding video processing app , submit app store when ios 8.1 came out. updated iphone xcode , hell broke loose. in simple single viewcontroller interface nil rotating anymore except statusbar, doesn't automatically hidden anymore in landscape mode...

i figured because using deprecated willanimaterotationtointerfaceorientation: little custom rotation actions had, implemented traitcollectiondidchange: , viewwilltransitiontosize: specs instead. viewwilltransitiontosize never gets called in app , traitcollectiondidchange: called once, @ startup. device isn't telling app device has rotated.

after googling i've tried using name:uideviceorientationdidchangenotification. @ to the lowest degree selector called 1 don't know how manually handle all rotation.

my didfinishlaunching... , viewdidload simple. alloc uiwindow, storyboard, set viewcontroller there, create rootviewcontroller, makekeyandvisible. based on 1 of apple's avfoundation demo apps. in didload add together subviews , toolbar etc, nil out of ordinary , did work on 8.0 , 8.0.2 on kinds of devices 7.1 simulator etc. still runs flawlessly on ipad 8.0.2... reason haven't posted code i'm 100% sure right on end.

main weird thing can't seem find problem. no errors in console or elsewhere either.

does have thought of might causing this? didn't think point release create such massive differences , again, no 1 else seems having this. issue/bug in actual storyboard file?

and, mainly, since can rotation notifications through uideviceorientationdidchangenotification, how manually handle rotation/resizing stuff? have been looking on answers no avail , out of time spend on project :(

cheers!

alloc'ing uiwindow problem.

first, create sure navigation controller (or whatever you're using) set "initial view controller" in storyboard.

secondly, in appdelegate.m file, remove references uiwindow , rootviewcontroller appear in application didfinishlaunchingwithoptions. in case, removing next 2 lines fixed issues.

self.window = [[uiwindow alloc] initwithframe:[[uiscreen mainscreen] bounds]]; [self.window makekeyandvisible];

you don't need set window's rootviewcontroller if using storyboards.

they're not needed when using storyboards, until 8.1 there never harm using them. took 2 days figure out, help , others too.

can tell me why not working?

this code has multiple syntax errors , don't see how could've run (missing ], duplicate properties in same object, etc).

my best guess haven't defined param1 parameter. can't utilize arbitrary parameters when transitioning state, must either part of url or defined in params state argument.

you telling operating scheme run programme named "p1", ".start()" first command line argument.

if you're on linux, it's same if typed "p1 .start" in shell window. if you're on windows, same if typed in cmd.exe window. either way, it's not going think it's going do.

the p1 in nthread p1=new nthread(thread.norm_priority + 4,printwriter); variable in java program. fact refers object can used start thread not cause programme named p1 magically appear on $path (or %path% if you're on windows.)

<asp:table id="table1" runat="server" borderwidth="2px" bordercolor="#0033cc" backcolor="#ffcccc" > <asp:tablerow> <asp:tablecell cssclass="table-cell-room" id="d256">d256<br /></asp:tablecell> <asp:tablecell><asp:button runat="server" width="100px" text="boka" id="r1b1" onclick="button_click_first_row" cssclass="buttons"/></asp:tablecell> <asp:tablecell><asp:button runat="server" width="100px" text="boka" id="r1b2" onclick="button_click_first_row" cssclass="buttons"/></asp:tablecell> <asp:tablecell><asp:button runat="server" width="100px" text="boka" id="r1b3" onclick="button_click_first_row" cssclass="buttons"/></asp:tablecell> <asp:tablecell><asp:button runat="server" width="100px" text="boka" id="r1b4" onclick="button_click_first_row" cssclass="buttons"/></asp:tablecell> <asp:tablecell><asp:button runat="server" width="100px" text="boka" id="r1b5" onclick="button_click_first_row" cssclass="buttons"/></asp:tablecell> </asp:tablerow>

i have database table called room , contains id, button_id , checkifbooked. want utilize "colum" checkedifbook see if booked, meaning checkedifbooked = 1.

all of work have no thought style buttons on table of have checkedifbooked = 1.

meaning in database table have r1b1 , it's value checkedifbooked = 1. have no thought code in page load. don't want utilize

if(button_id == r1b2){ checkedifbooked == 1 //do styling on button }

cause have alot of buttons , in c# code utilize sender new button right id button clicked.

possible solution #1

when rendering page, add together additional css class button if isbooked = true

if (isbooked) { /// render "isbooked" tablecell button <asp:tablecell> ... cssclass="isbooked"/></asp:tablecell> } else { /// render "not booked" tablecell button <asp:tablecell> ... cssclass="button"/></asp:tablecell> }

then in css:

.isbooked { /* isbooked button styles here */ }

so when code gets rendered html, css classes in place:

<!-- illustration html output --> < ... class="button" ... ></> < ... class="isbooked" ... ></> < ... class="button" ... ></> possible solution #2

on page load, have jquery booked buttons, , disable them, or style them, etc..

$(document).ready(function(){ $("isbooked").each(function(index){ // each isbooked element available via $(this) $(this).addclass("bookedbutton"); $(this).prop("disabled", true); // ... }); });

security note: disabling form button on client-side (via javascript) isn't enough, need validate info on server side. if disable form elements on client, create sure server verifies nil "booked" trying submitted form.

hope helps.

C memory allocation affects char array length -

C memory allocation affects char array length -

#include <stdio.h> #include <stdlib.h> #include <string.h> int main(int argc, char *argv[]) { //step 1 char *key = malloc(10000); int *arr = malloc(sizeof(int)); free(arr); free(key); //step 2 char *msg = malloc(10000); printf("size: %zu \n", strlen(msg)); free(msg); homecoming 0; }

could explain this:

if execute both step 1 , 2, length of msg 6, 4 if exectue both step 1 , 2, without allocation , freeing of key, length 0 if execute step 2, length of msg 0

why allocation of int , key array impact length of char array? realize strlen requires '\0' char, why behave different?

char *msg = malloc(10000); printf("size: %zu \n", strlen(msg));

msg allocated, not initialized, undefined behavior phone call strlen(msg).

in cases, perhaps happens in uninitialized memory allocated malloc, first 0 appeared @ different places.

winapi - difference between GetDesktopWindow() and HWND_DESKTOP -

winapi - difference between GetDesktopWindow() and HWND_DESKTOP -

there's win32 api function, getdesktopwindow(), returns handle of desktop window.

and there's 1 - hwnd_desktop macro. couldn't find official info in msdn, it's found in winuser.h

#define hwnd_desktop ((hwnd)0)

so, what's difference between them?

hwnd_desktop used mapwindowrect() indicate using screen coordinates, as documented on msdn. you'll notice value equal null, listed there. i'm guessing hwnd_desktop came first.

of course, valid windows cannot null real, hwnd_desktop isn't handle of desktop window. while don't know of real things can it, proper way desktop window's handle function.

(for it's worth, illustration getdesktopwindow() uses returned handle position dialog box on screen. don't know if current preference utilize current monitor's work area instead...)

regex - Regular expression for number in JavaScript -

regex - Regular expression for number in JavaScript -

i want regular look numbers, not less 3 , more 7 digit , should not take characters.

i tried (/^[0-9]{3,7}$/) - accepting character 'e'. eg: 1e3, 23e4, 123e4 failing.

my guess 1e3 number written in engineering notation, not string. e means "times 10 powerfulness of", 1e3 means 1 x 10^3 = 1000, , 23e4 means 230000. if case, when convert number 1e3 string, output "1000", represents number not less 3 digits , not more 7, right regex matches this.

how can modify code utilize multiple divs code takes id of div. so, have replicate each div. there other way?

there dozens of different ways accomplish goal , here 1 of them: http://jsfiddle.net/2rw84usl/

html:

multithreading - cudaDeviceSynchronize() waits to finish only in current CUDA context or in all contexts? -

multithreading - cudaDeviceSynchronize() waits to finish only in current CUDA context or in all contexts? -

i utilize cuda 6.5 , 4 x gpus kepler.

i utilize multithreading, cuda runtime api , access cuda contexts different cpu threads (by using openmp - not matter).

when phone call cudadevicesynchronize(); wait kernel(s) finish in current cuda context selected latest phone call cudasetdevice(), or in cuda contexts?

if wait kernel(s) finish in cuda contexts, wait in cuda contexts used in current cpu thread (in illustration cpu thread_0 wait gpus: 0 , 1) or cuda contexts (cpu thread_0 wait gpus: 0, 1, 2 , 3)?

following code:

// using openmp requires set: // msvs option: -xcompiler "/openmp" // gcc option: –xcompiler –fopenmp #include <omp.h> int main() { // execute 2 threads different: omp_get_thread_num() = 0 , 1 #pragma omp parallel num_threads(2) { int omp_threadid = omp_get_thread_num(); // cpu thread 0 if(omp_threadid == 0) { cudasetdevice(0); kernel_0<<<...>>>(...); cudasetdevice(1); kernel_1<<<...>>>(...); cudadevicesynchronize(); // kernel<>() wait? // cpu thread 1 } else if(omp_threadid == 1) { cudasetdevice(2); kernel_2<<<...>>>(...); cudasetdevice(3); kernel_3<<<...>>>(...); cudadevicesynchronize(); // kernel<>() wait? } } homecoming 0; }

when phone call cudadevicesynchronize(); wait kernel(s) finish in current cuda context selected latest phone call cudasetdevice(), or in cuda contexts?

cudadevicesynchronize() synchronize host set gpu, if multiple gpus in utilize , need synchronized, cudadevicesynchronize() has called separately each one.

here minimal example:

cudasetdevice(0); cudadevicesynchronize(); cudasetdevice(1); cudadevicesynchronize(); ...

so, reply cudadevicesynchronize() syncs streams in current cuda context

you should insert content before table of contents/toc title after:

\usepackage{tocloft} \renewcommand{\cfttoctitlefont}{\hfill<titlefont>} \renewcommand{\cftaftertoctitle}{\hfill\mbox{}}

<titlefont> represents font switches you're interested in making. adjustments list of figures/lof (list of tables/lot), utilize \cftloftitlefont , \cftafterloftitle (\cftlottitlefont , \cftafterlottitle).

c - Difference between u8, uint8_t, __u8 and __be8 -

c - Difference between u8, uint8_t, __u8 and __be8 -

while browsing linux networking code, came across these datatypes:

u8 uint8_t __u8 __be8

(same things 16, 32 , 64 bits)

can please explain difference between these datatypes , utilize which? have seen definitions of these datatypes not clear me.

uint8_t standard c , represents unsigned 8-bit integral type. if on scheme not have 8-bit addressable units not defined; otherwise typedef unsigned char.

anything __ in reserved implementation use. means compiler writers , standard library writers can utilize identifiers without worrying name clash user code. may see when looking in internals of standard library implementation.

u8 non-standard means same uint8_t. reason u8 might used in code written before uint8_t added standard c.

javascript - Restrict container/parent for Sortable -

javascript - Restrict container/parent for Sortable -

ok, here again, playing @rubaxa's sortable plugin (and somewhere around here, 1 rather complicated...)

a few discoveries (it took me time understand mechanism, think i'm quite right)

case 1

if set 1 div same-type contents, it's instantly sortable. e.g.:

html

<div id="mycontainer"> <h3>item 1</h3> <h3>item 2</h3> </div>

javascript

new sortable(document.getelementbyid("mycontainer"));

demo: http://jsfiddle.net/b02wfe4o/

case 2

if set 1 div different-type contents (e.g. h2s , h3s, have specify draggable class. e.g.:

html

<div id="mycontainer"> <h3 class="mydraggable">item 1</h3> <h4 class="mydraggable">item 2</h4> </div>

javascript

new sortable(document.getelementbyid("mycontainer"), { draggable: '.mydraggable' });

demo: http://jsfiddle.net/qemz00eq/1/

case 3

if set 2 (or more) divs, side-by-side, works pretty much same way. e.g.:

html

<div id="mycontainer1"> <h3 class="mydraggable">item 1.1</h3> <h4 class="mydraggable">item 1.2</h4> </div> <div id="mycontainer2"> <h3 class="mydraggable">item 2.1</h3> <h4 class="mydraggable">item 2.2</h4> </div>

javascript

new sortable(document.getelementbyid("mycontainer1"), { draggable: '.mydraggable' }); new sortable(document.getelementbyid("mycontainer2"), { draggable: '.mydraggable' });

demo: http://jsfiddle.net/qeyxxj4y/

the issue

now, if sortable kid of sortable b?

html

<div id="mycontainer1"> <h3 class="mydraggable">item 1.1</h3> <h4 class="mydraggable">item 1.2</h4> <div id="mycontainer2"> <h3 class="mydraggable">item 2.1</h3> <h4 class="mydraggable">item 2.2</h4> </div> </div>

javascript

new sortable(document.getelementbyid("mycontainer1"), { draggable: '.mydraggable' }); new sortable(document.getelementbyid("mycontainer2"), { draggable: '.mydraggable' });

demo: http://jsfiddle.net/j7feslkp/8/

well, not work expected:

mycontainer2 items can moved/sorted within container. fine. mycontainer1 items though can moved in mycontainer2 well, mean take element 1.1 , set within mycontainer2 works - wasn't happening when 2 containers side-by-side.

so, how can disable behaviour? mean: each container's items must move within container , not within children.

how can done?

you gave separate sortables, , split them in 2 different groups. alter class of 1 of groups in html , js initialize them group.

Using REST to fetch SharePoint View Items -

i trying build right url homecoming items in sharepoint view using rest api.

using browser , next url can homecoming items in list.

https://mysharepoint.sharepoint.com/sites/mysite/_api/web/lists/getbytitle('announcements')/items

and can view definition using next url.

https://mysharepoint.sharepoint.com/sites/mysite/_api/web/lists/getbytitle('announcements')/views/getbytitle('latest news')/

but cannot figure out need set @ end of url items returned the view.

sp.view object not contain methods manipulating list items. sp.view object contains sp.view.viewquery property specifies query used list view. means next approach used retrieving list items view:

perform first request caml query list view using sp.view.viewquery property perform sec request retrieve list items specifying caml query how homecoming list items list view using rest api using javascript function getjson(url) { homecoming $.ajax({ url: url, type: "get", contenttype: "application/json;odata=verbose", headers: { "accept": "application/json;odata=verbose" } }); } function getlistitems(weburl,listtitle, querytext) { var viewxml = '<view><query>' + querytext + '</query></view>'; var url = weburl + "/_api/web/lists/getbytitle('" + listtitle + "')/getitems"; var querypayload = { 'query' : { '__metadata': { 'type': 'sp.camlquery' }, 'viewxml' : viewxml } }; homecoming $.ajax({ url: url, method: "post", data: json.stringify(querypayload), headers: { "x-requestdigest": $("#__requestdigest").val(), "accept": "application/json; odata=verbose", "content-type": "application/json; odata=verbose" } }); } function getlistitemsforview(weburl,listtitle,viewtitle) { var viewqueryurl = weburl + "/_api/web/lists/getbytitle('" + listtitle + "')/views/getbytitle('" + viewtitle + "')/viewquery"; homecoming getjson(viewqueryurl).then( function(data){ var viewquery = data.d.viewquery; homecoming getlistitems(weburl,listtitle,viewquery); }); }

usage

getlistitemsforview(_sppagecontextinfo.webabsoluteurl,'announcements','latest news') .done(function(data) { var items = data.d.results; for(var = 0; < items.length;i++) { console.log(items[i].title); } }) .fail( function(error){ console.log(json.stringify(error)); });

linux - How to parse MySQL slow query log for last 24 hours of entries -

linux - How to parse MySQL slow query log for last 24 hours of entries -

i'd process mysql slow query log , retrieve lastly 24 hours of entries, log rotation isn't alternative @ present.

below illustration log entry

# query_time: 0.000431 lock_time: 0.000124 rows_sent: 8 rows_examined: 25 set timestamp=1415792064; select `username`, `password`, `date_created` joomla_users order `kid` desc; # user@host: joomla[joomla] @ [192.168.168.100]

i utilize awk or grep or similar solution executed via command line or part of script identify entries placed in mysql slow query log file within lastly 24 hours comparing "set timestamp" line each entry , place said entries separate log file.

i recommend using percona toolkit's query digest tool sort of analysis. it's straightforward install , you'd want analysis of slow queries (analyze them based on query footprints, not individual arguments in queries, exclude types of queries based on regex expressions, etc)

take percona toolkit (http://www.percona.com/doc/percona-toolkit/2.1/pt-query-digest.html). if decide utilize it, next code should easy adapt

pt-query-digest --since '2014-11-01' --filter '$event->{arg} =~ m/^select/i' /var/log/mysql/mysql-slow-query.log > /tmp/pt_slow_nov

what that's saying analyze queries 2014-11-01 onward, @ select queries, read slow query log /var/log/mysql/slow-query.log (obviously you'll need reference file location) , output analysis /tmp/pt_slow_nov. if you're familiar grep , awk, should pretty straightforward parameterize --since portion of query , stick in cron.

android - savedInstanceState memory implications -

android - savedInstanceState memory implications -

i working on android project few other developers , bug raised instance states not beingness retained on garbage collection:

the actual bug reported:

the app has 1 activity bunch of fragments. if "don't maintain activities" checked in developer options , user clicks on button changes visible fragments, , navigates away app , back, relaunches app original state instead of lastly state.

another dev on project raised next concern:

"the saving of instances cause apps in memory size bloat. already, because of amount of drawables, apps memory size high.

its ok, if app restarts after while of non usage user."

my understanding savedinstance bundle gets written physical memory, not correct? above quote valid concern?

my understanding savedinstance bundle gets written physical memory, not correct?

i interpreting "written physical memory" meaning "written file on filesystem" (a.k.a., "persisted").

the instance state bundle not persisted. android 5.0+ gives different hook persistablebundle is persisted , hence survives reboot.

however, instance state bundle passed across process boundaries core os process. info can used if process terminated, user returns app while task still around (e.g., via recent-tasks list).

is above quote valid concern?

the piece of quote reasonably evaluated people here on is:

the saving of instances cause apps in memory size bloat

saving 1 byte in bundle consume more memory saving 0 bytes in bundle. hence, mathematically, quote accurate. key maintain bundle small. can't big anyway other reasons (1mb limit ipc calls). little instance state bundles should not problem.

ruby - Only allow module to define method if including class/module does not -

ruby - Only allow module to define method if including class/module does not -

i'm having lots of fun activemodel's serialization, tangled web of as_json , serializable_hash.

my app has big collection of models share behavior including module, we'll phone call sharedbehavior.

my team has decided have default format want these classes follow when beingness cast json (for rendering in rails app), of them should behave little differently. due odd behavior in these 2 methods activemodel library, adding whitelisted or blacklisted attributes in models gets overridden method definition in module, , passed on super declarations in activemodel.

for reason, i'd module apply definition of these methods models if not explicitly overridden in models (in essence, take module out of ancestor chain few method calls), still need shared behavior module.

i tried solving conditionally, dynamically applying method on module inclusion in irb:

class def foo puts 'in a' end end module d def self.included(base) unless base.instance_methods(false).include?(:foo) define_method(:foo) puts 'in d' super() end end end end class b < include d end class c < include d def foo puts 'in c' super end end

with declaration, expected output of c.new.foo be

in c in

but instead

in c in d in

my other thought move logic out module , include module in every class (there 54 of them) not explicitly override method, there couple downsides that:

it introduces bit of implicit coupling in project new model include module iff not want override method implementation the current implementation of these serialization methods in module have behavior , attributes established module, sense unintuitive have sec module knows , depends on implementation details of sharedbehavior, though sec module have nil first.

can else think of solution, or maybe spot oversight of mine in code illustration above allow me create phone call in included hook? (i tried switching order in c class defined foo method , included d module, saw same behavior).

there 2 tricky bugs here.

ruby evaluates classes, order of expressions matters. include d before defining foo in c, when included hook called, foo won't defined in base. need include d @ end of class. you're defining foo in d. after including d in b, d#foo defined, meaning it's still included in c if prepare previous bug. need base receiver of define_method.

but there's interesting twist: fixing sec bug makes first bug irrelevant. defining foo in base directly, overwritten later definitions. doing

class c < def foo puts 'in d' super() end # overwrites previous definition! def foo puts 'in c' super end end

so summarize, need

# in d.included base.class_eval define_method(:foo) puts 'in d' super() end end

find verified status for a list of facebook pagenames -

i have 782 facebook page links page names in excel file. want find out how many of them verified fb. started find solution. got few articles not relevant question , relevant had limited info or not understand. after searching bit more have home wrote code given below not echo verified status. how can utilize if need check 782 pagenames. please help...

<?php function verified($pagename){ // query in fql $fql = "select is_verified"; $fql .= " page username = '$pagename'"; $fqlurl = "https://api.facebook.com/method/fql.query?format=json&query=" . urlencode($fql); // facebook response in json $response = file_get_contents($fqlurl); homecoming json_decode($response); } $fb = verified('nokia'); echo $fb[0]->is_verified; ?>

edit: more info: searched , found can done using fql , api v21 both

https://graph.facebook.com/fql?q=select is_verified page username=nokia nokia/?fields=is_verified

here documentation

https://developers.facebook.com/docs/reference/fql/page/

i want help in getting code repaired , need if have check 782 pagenames. presently have set links in mysql mytable table , trying out things. help here appreciated.

i believe verified status not in page table (anymore), not show in docs: https://developers.facebook.com/docs/graph-api/reference/v2.1/page

also, fql deprecated , not work in newer apps anymore, see changelog: https://developers.facebook.com/docs/apps/changelog

i think there no way check if page verified, unfortunately. way how may possible fql using app created before apr 21st, 2010. is, before v2.1 came out, without fql.

Why http post on android fails over 3g? -

Why http post on android fails over 3g? -

i have android application makes http post request server containing namevaluepairs, , works fine on wifi network, when utilize same http post on 3g, server gets http request empty body. here code request

list<namevaluepair> namevaluepairs = new arraylist<namevaluepair>( 3); namevaluepairs.add(new basicnamevaluepair("name", params[0])); namevaluepairs.add(new basicnamevaluepair("dni", params[1])); namevaluepairs.add(new basicnamevaluepair("token", params[2])); url url = new url(url_server); httpurlconnection conn = (httpurlconnection) url .openconnection(); conn.setreadtimeout(30000); conn.setconnecttimeout(50000); conn.setrequestmethod("post"); conn.setdoinput(true); conn.setdooutput(true); outputstream os = conn.getoutputstream(); bufferedwriter author = new bufferedwriter( new outputstreamwriter(os, "utf-8")); writer.write(getquery(namevaluepairs)); writer.flush(); writer.close(); os.close(); conn.connect(); int responsecode = conn.getresponsecode(); bufferedreader in; if (responsecode == 404) in = new bufferedreader(new inputstreamreader( conn.geterrorstream())); else in = new bufferedreader(new inputstreamreader( conn.getinputstream())); string inputline; stringbuffer response = new stringbuffer(); while ((inputline = in.readline()) != null) { response.append(inputline); } in.close();

here code getquery method

private string getquery(list<namevaluepair> params) throws unsupportedencodingexception { stringbuilder result = new stringbuilder(); boolean first = true; (namevaluepair pair : params) { if (first) first = false; else result.append("&"); result.append(urlencoder.encode(pair.getname(), "utf-8")); result.append("="); result.append(urlencoder.encode(pair.getvalue(), "utf-8")); } homecoming result.tostring(); }

any thought why happens?

i have new info. made form send http post on web browser. form works great , sends body on 3g on windows phone , on wifi. when seek utilize chrome of android phone on 3g send http post, arrives empty, , if seek send http post 1 computer connected hotspot of android phone fails. when seek same computer connected wifi network, no problem @ all. weird. ideas?

my advice utilize google's volley library networking. pretty much best selection when comes networking on android. should not 3g problem. if is, problem might isolated one.

here have resources at(volley easy use):

node.js - How Do I Assign LDAP Password Via LDAPjs? -

i'm using ldapjs.

i got code sites:

var newuser = { cn: 'new guy', sn: 'guy', uid: 'nguy', mail: 'nguy@example.org', objectclass: 'inetorgperson', userpassword: ssha.create('s00prs3cr3+') }

the thing is, password saved octetstring, , can't used login. here knows how assign password using node (ldapjs preferred)?

try saving in plain text.

most ldap server implementations expect receive password in plain text , server encrypt password.

there dependancies on ldap server implementation , configuration.

-jim

oh, did not mention ad. active directory quite different. uses unicodepassword, not userpassword. password operations must on encrypted connection. , finally, password must "text value in utf-16". quotes required.

readobject parses input , returns object, if there one. if not throw arrayindexoutofboundsexception.

i wondering if there way validate contents provided xmldecoder (in illustration above file content of "test.xml") in advance xmldecoder can work it.

c# - PDFsharp blank pages issue -

c# - PDFsharp blank pages issue -

i have been using pdfsharp merge 2 pdfs in 1 document , print it. seems working fine of time, whenever under heavy load (even making 4 simultaneous post requests) of printed pages blank. known issue pdfsharp , if is, have fix?

what testing?

i trying print 3 pages in duplex part of 1 request , have been testing 4 simultaneous calls. so, altogether have 12 pages.

result

i getting half of pages blank (so 5-6 pages).

another test did – did test made 100 requests (so printed 100 * 3 = 300 pages) , pages came out fine. however, making 1 request, waiting finish , 1 time finished made requests. seems suggest pdfsharp not able print documents correctly when used in asynchronous manner. however, part of application have create asynchronous requests waiting 1 request finish not option.

ps - using latest pdfsharp version 1.32

the generated (concatenated) pdf fine, there no blank pages in it. when printed blank pages.

pdfsharp not print pdf files @ all. cannot blame pdfsharp if printing fails under heavy load.

afaik pdfsharp not thread-safe (like libraries). if manipulate several pdf files @ same time, have utilize different threads - 1 thread each pdf file.

most utilize adobe reader print pdf files. may have serialize calls adobe reader.

c++ - emscripten issue with ubuntu version "aborting from js compiler due to exception: unknown vector type | undefined" -

c++ - emscripten issue with ubuntu version "aborting from js compiler due to exception: unknown vector type <4 x i8> | undefined" -

i cannot compile current version of emscripten ubuntu repos

here error

http://pastebin.com/j5z0ztts

i suspect might because emscripten outdated in repos, why there no bug reports??

could help? cannot find updated information.

thanks in advance.

the reason because using /usr/bin/clang++ comes linux distribution.

this version not back upwards javascript backend. in order utilize emscripten, you have compile fastcomp (an llvm clang compiler javascript backend added)

if have not built fastcomp yet, emscripten won't work.

check out page installation instructions:

http://kripken.github.io/emscripten-site/docs/building_from_source/llvm-backend.html

if have built fastcomp, problem in emscriptenrc file, , path.

this how worked around issue:

i created file called emscriptenrc.sh did this:

export path=/home/mike/emscripten/fastcomp/build/master/bin:/home/mike/emscripten/fastcomp/build/master/include:/home/mike/emscripten/fastcomp/build/master/lib:$path

then after created file

i rebuilt ~/.emscripten configuration file calling

./emcc -v emscripten build directory -- seemed right version of clang registered...

now can go ahead , compile emcc

i suggest reading http://kripken.github.io/emscripten-site/docs/building_from_source/llvm-backend.html rest of documentation prior trying utilize emscripten.

java - Why does this method not return whether the area is bigger than the parameter cubed? -

java - Why does this method not return whether the area is bigger than the parameter cubed? -

i'm working on minecraft plugin protect area. have area class created after player selects 3 blocks, , area class has method named "toobig", used detecting if area bigger if "block^3". problem method returns false.

public boolean toobig(int i) { boolean bo1, bo2, bo3; bo1 = math.abs(b1.getx() - b2.getx()) > i; bo2 = math.abs(b1.getz() - b2.getz()) > i; bo3 = math.abs(b1.gety() - b3.gety()) > i; homecoming bo1 && bo2 && bo3; }

b1, b2, , b3 block objects.

your utilize of variables inconsistent.

public boolean toobig(int i) { boolean bo1, bo2, bo3; bo1 = math.abs(b1.getx() - b2.getx()) > i; bo2 = math.abs(b1.getz() - b2.getz()) > i; bo3 = math.abs(b1.gety() - b3.gety()) > i; homecoming bo1 && bo2 && bo3; }

your algorithm wrong altogether. formula of calculating volume of rectangular cuboid region is

base (length * width) * height

where length, width , height of cuboid the distance maximum point through axis minimum point instead of randomly 2 points subtracting. right code getting area be:

public boolean toobig(int i) { int minx = math.min(math.min(b1.getblockx(), b2.getblockx()), b3.getblockx()); int maxx = math.max(math.max(b1.getblockx(), b2.getblockx()), b3.getblockx()); int miny = math.min(math.min(b1.getblocky(), b2.getblocky()), b3.getblocky()); int maxy = math.max(math.max(b1.getblocky(), b2.getblocky()), b3.getblocky()); int minz = math.min(math.min(b1.getblockz(), b2.getblockz()), b3.getblockz()); int maxz = math.max(math.max(b1.getblockz(), b2.getblockz()), b3.getblockz()); int area = (maxx - minx) * (maxy - miny) * (maxy - miny); }

to create work:

return area > math.pow(i, 3);

your problem not taking business relationship size of each element of array. each element occupies 4 bytes. therefore, instead of issuing

add together $a1,$a1,$s0 # homecoming address of b[k]

you should multiply index 4 (which size of element) effective offset:

sll $s1, $s0, 2 # compute effective offset (i.e. multiply index 4) add together $a1,$a1,$s1 # homecoming address of b[k] lw $t3,0($a1) # value of b[k] , save t3
