i want search string in sphinx , documents contains string example: search "bot" , documents contain "xbot", "robot", "botanic", etc basically want search have same effects running select * table column_name '%bot%' how can that? note : tried use min_infix_len seems extends search little bit not fully. if set conf-min-prefix-len = 2 match 'xbot' not "botanic" try using wildcard in extended query syntax , min_infix_len enabled select * myindex match("bot | bot* | *bot*")

is right way match 2 divs? var div2 = document.getelementsbyclassname("div2"); div2.style.borderradius = "100px" document.getelementbyid("div1").style.borderradius = div2.style.borderradius; just newbie @ javascript. just comment on code, document.getelementsbyclassname() returns htmlcollection, not single dom element. should use document.getelementbyid() or document.queryselector() if you're trying 1 element. and don't want use js add styling, unless styling want use dynamic. case, should use css file , add class: .round-border { border-radius: 100px; } if still want use js add class instead of putting in html, can following: document.getelementbyid("div1").classlist.add('round-border'); document.getelementbyid("div2").classlist.add('round-border'); this assuming gave html elements correct id names. but said, because using static value of 100px , make more sense add class eleme

i creating backend animating progress bar. // default easing. tweenlite.defaultease = power0.easenone; // timeline. var tl = new timelinelite({ onupdate : function() { console.log(progress.progress); } }); // initial state. var progress = { progress : 0 }; // finalized state. tl.to(progress, 1, { progress : 100 }); // length of animation. tl.totalduration(15); // play. tl.play(); this works expected, there way animate current playhead specific one ? tl.playto(0.5) , afterwards tl.playto(0.2) revert 20%. i aware of seek , progress , optional variable play methods, let me specify starting position, not end position. how achieve such behavior? if understand question correctly, here propose. you can animate progress property of timelinelite . like: tweenlite.to(tl, 1, {progress: .5, ease: linear.easenone}); . also, have seen tweento() , tweenfromto available in timelinemax , know using timelinelite still wondering if aware of th

in program i'm writing, user needs able select cell in grid , edit value. program shows value of selected value in hexadecimal (so (0,0) 0x00 , (1,3) 0x19 , etc.) had display updated through binding wx.grd.evt_grid_select_cell event. however, upon doing this, gridcursor no longer move, stay on (0,0). so, added setgridcursor statement handler have move cursor when handler called. however, generated infinite loop, apparently setgridcursor generates evt_grid_select_cell command when called. my question is, how have code executes when new cell selected while still maintaining old cell selection functionality? adding event.skip() @ end of custom handler passes event default handler.

this question has answer here: segmentation fault doesn't come after accessing out-of-bound memory 5 answers what's stored after end of character array? assuming there random garbage did not print after end while looping 10 times. char a[] = "pencil"; int i; (i = 0; < 10; i++) { printf("%c", a[i]); } so character array has size of 7. , loop looped until 10th position 3 more values looped through. did not print or error. what's going on here? accessing beyond end of array in c undefined behavior. program continue running unchanged or crash horrifically depending on stored past end of array. compiler makes no guarantees stored there - useless memory or critical program.

this question has answer here: scope of python variable in loop 7 answers i learning python , came across 'for loop' let's have program asks 5 numbers. know it's pointless it's example. anyway, if did this, wouldn't restart cycle. mynumbers = [] x in xrange(5): try: mynumbers.append( int(raw_input()) ) except valueerror: mynumbers = [] x = -1 i thought if had reset x -1 make loop go on more, never restarted. still only went 5 times. reason why put -1 there because x count 0 right after that. tried find solutions, there weren't any. thank if try me. xrange() (or range() ) called generator functions, x local variable loop assigns next value in loop to. xrange() returns values in range given in parameters 1 1 , , loop assigns variable x. if change value of x within loop, xrange() has no ide

class { public final static float _eps = 1e-7f; public final static double _eps2 = 1e-7; public static boolean compare(float a, float b) { return < b + _eps; } public static boolean compare2(float a, float b) { return < b + _eps2; } public static void main(string [] main) { float = 54.124844f; float b = 54.124844f; system.out.println("compare 1: " + a.compare(a, b) + " comapre 2: " + a.compare2(a, b)); } } i thought both of these 2 comparisons return true, but, a.compare return false. reason in mind because of range , precision difference between float , double type. however, seems number , eps used should within legal range. help. this because 54.124844f + 1e-7f == 54.124844f . float doesn't have enough precision addition yield value different 54.124844f . using math.nextafter(float, double) shows next larger value after 54.124844f 54.124847f . such,

i have following: function functiona() { var myvar = functionb(); functionc(myvar); } the time, functionb needs answer, depends on user input. may 1s, 10s. functionc called undefined value, because functionb() hasnt't finished yet. tried this: function functiona() { var def = $.deferred(); var myvar = functionb(); def.resolve(); $.when(def).done(function () { functionc(myvar); }); } this doens't work. saw on stackoverflow: javascript function wait until function finish how can transferred problem? recap, execution of functiona needs stop, until functionb() has answered. thanks. you can change functionb return deferred object, can resolve within async handler, this: function functiona() { var deferred = functionb(); $.when(deferred).done(functionc); } function functionb() { var deferred = $.deferred(); // async here... // asynccallback() { // deferred.resolvewith(this, dataretrieved);

im using node js aplication , i've created new js file module , in module export 1 function,in module lets i've additional 2 functions internal use only , should not exposed outside, each function use different require modules following: module.exports = function (app, express) { var bodyparser = require('body-parser'), url = require('url'), http = require('http'); ..... }; function prrequest(req, res) { httpproxy = require('http-proxy'); .... } function postrequest(req, res) { url = require('url'); .... } my question best practice should put require (for url http etc) 1.inside every function need it?in case internal , external 2.globally in file every function can use? 3.if 2 not ok should put require url should use in 2 functions?better put in both function or in global or doesn't matter the modules should exposed outside functions calling require each time functi

there many posts got use case of __init__.py , use define global variable 1 of them. want know there demerit in defining local variable in __init__.py ? there no technical reason prevents using __init__.py declaring global variables. nevertheless, mean of __init__.py modules define import structure of application. python documentation: the __init__.py files required make python treat directories containing packages; done prevent directories common name, such string, unintentionally hiding valid modules occur later on module search path. in simplest case, __init__.py can empty file, can execute initialization code package or set __all__ variable, described later. as developer, expect find in __init__.py file import layout of application itself. it's last place when i'm exploring source code. therefore, hiding implementation in __init__.py misleading. true global variable lifecycle definition hard follow. it's considered bad practice because brea

i have issue in microsft access have table detailing amount of money paid client identifier particular month. table has not been set primary key table contains 1 record each payment made rather 1 record each individual includes every payment. see link clearer picture. the top table on image have linked example of have , bottom table hoping achieve. can advise me on best way achieve i'm looking for? i'd grateful if direct me somewhere teach me have never used access before , i'm keen learn. it seem me top image setup correctly database. if there single payment per month, make first 2 columns composite key...otherwise, 3 columns composite key. wouldn't want have go in every single month , create new columns month , total payment. database growing in wrong direction. if wanting use bottom image, think excel fine. also...i don't see duplicate records. having multiple rows same id pretty want in case.

i started adding e2e tests our project , seems few things changed since last time used protractor. example elementexplorer still useful, elementor way more cooler. in readme says launch running e.g.: webmanager start , elementor http://localhost:3000 . but way ignores protractor.conf. , since have binary path chrome browser in file, along logic clearing cookies , logging app in onprepare function, protractor has know file is. can't find way. starting protractor usual via protractor protractor.conf.coffee , elementor localhost:3000 not working either. says "unable start webdriver session" yes, should launch running webdriver-manager start , use run scripts: protractor script_file_conf.js since save scripts javascript code in repository. remember conf file should have reference script file.

i'm pretty new programming , java, i'm not sure. know jdk has own compiler , jre need eclipse? you need jre run java code on computer , jdk write it. however, many programmers tend prefer ide (integrated development environment) use along side writing code, debugging, , execute more efficiently. eclipse example of one, , 1 of many used/preferred ide's (in opinion @ least) out there. however, others exist too: drjava netbeans bluej jcreator these editors more preferred because make easier learn / write code. however, may choose normal text editor (like sublime, atom, textedit, notepad, textmate, etc..) or command line. mac & linux have "vim" built in command line editor tend prefer.

i think understand semantics of various memory_order flags in c++ atomic library. however, i'm confused following situation: suppose have 2 threads - thread a, "main execution" thread, , thread b, arbitrary thread part of thread pool tasks can scheduled , run. if perform "read-write-update" atomic operation using std::memory_order_acq_rel , perform non-atomic write on boolean variable, non-atomic write visible other threads? think answer no, unless other threads access atomic variable did "read-write-update" operation. so, example, given global std::atomic_flag variable x , global bool value b, , thread pool object threadpool has member function dispatch , execute arbitrary function handlers in thread: if (!x.test_and_set(std::memory_order_acq_rel) { if (some_condition) b = true; threadpool.dispatch([]() { // executes in thread b if (b) { /* */ } // guaranteed see changes b? }); } so in example, code inside

so developing website company , may have, approx 1,000-5,000 profiles (of vendors , users), have store approx 10 images per vendor on directory on website's server (which retrieved using php), wondering better performing way it. have 2 choices: having images profiles in single folder (single folder having 10,000 images) having separate directories profiles having 10 images each (1,000 folders having 10 images each.) so way should performance of website, on server running linux, better? know @ scale, may not matter concern, may expand, have more profiles , server using slow (you can see impact in performance after include php file). i'll using like: <?php ($i = 1; file_exists("img/vendors/vendor_id_".$i.".jpg"); $i++) { echo "<img src=\"img/vendors/vendor_id_".$i.".jpg\">"; } ?> or <?php ($i = 1; file_exists("img/vendors/vendor_id/".$i.".jpg"); $i++)

in fictional stylesheet several media query sections rules within relevant media query processed browser, example @media screen , (max-width: 400px) { .container { width: 95%; } } @media screen , (max-width: 800px) { .container { width: 80%; } } .container 95% wide on screen maximum width of 400px. my question this: though media query max 400px 1 relevant (in fictional example), media query max 800px cached browser, though irrelevant, or not? the browser might cache entire css file these media queries contained in, browsers not cache particular sections of css file. so answer question, yes browser might cache non-active part of media query since might (and will) cache entire css file.

i tried search question didn't find previous topic. hope didn't miss it. :) anyway; have program open image, applies couple of image enhancing algorithm , save results in folder. works normal images but, obviously, doesn't work hdr files. indeed, if select ".hdr" image , give run, behave didn't gave him image @ all. is there library allow me open , work (open , save) on kind of files? hdr images have high dynamic range. can't open , save in format (like can open jpg , save bmp). there regions bright, , others dark. so need sort of post processing (gamma correction , tone mapping) before storing standard dynamic range format. photoshop that. , there other commercial tools (search hdr processing). if you're looking free, imagemagic or blurate can extent, aren't advanced, , need tweaking.

this algorithmic problem bit complex me: i have numpy array of data internally indexed in peculiar way. data output of 2 arrays spliced (which don't have), distinct ordering. set parameter max positive integer, , data output has index format [ 00 10 20 ... max0 11 12 ... max1 22 23....max2 33....max max ] the parameter max determines output of array (i.e. length of array) , ordering. for several examples, max=2 , data of order [00 10 20 11 21 22] setting max=3 gives [00 10 20 30 11 21 31 22 32 33] and max=4 [00 10 20 30 40 11 21 31 41 22 32 42 33 43 44] and on. i write algorithm make list/array of 3x values, i.e. values first index 3. is, access certain data values, organized first index. however, determined parameter max . can see, determines datum placed array index. idea make sort of sorting tree, not sure how execute max parameter. this list comprehension (or iteration) produces indexs show [[j*10+i j in range(i,max+1)] in range(max

this seems simple don't know i'm doing really. have 2 radio buttons , depending on 1 selected contents of div change. right have 2 divs inside parent div hide 1 div , show other. wouldn't bad if didn't take space when they're invisible. html: <div> <form role="form"> <div> <div class="radio" id="radioselection" onchange="choosediv()"> <label> <input type="radio" name="optradio" id="selectiondiv1" checked />choose div1 </label> <label> <input type="radio" name="optradio" id="selectiondiv2" />choose div2 </label> </div> </div> </form> </div> <div id="parentdiv"> <div id="div1">you're awesom

working on project in ios 8 using storyboard , auto layout: in storyboard, specified constraints view , subviews in code, in response touch events, i'm going change view's size setting frame to make both 1 , 2 warning free, i'm doing following when first changing size code: [theview removeconstraints:theview.constraints]; theview.translatesautoresizingmaskintoconstraints = yes; theview.frame = cgrectmake(0,0,width,height); if not doing first line, xcode complain whole bunch constraint conflicts, adding line remove subview's constraints well. question is: there way remove uiview's constraints not subview, button on still wants center self relative view's size , position? first, don't need resize view setting frame otherwise point of keeping constraint @ first place. have position having correct initial frame. secondly, have mis-conception "to-whom" constraint has been applied to. say button on still wants center self
