i have 2 divs, 1 white background, 1 black background: <style> #leftside { float:left; width:50%; height:100%; background:#fff; } #rightside { float:right; width:50%; height:100%; background:#000; } <div id="leftside"> </div> <div id="rightside"> </div> what wish write text goes on both of divs has inverted color depending on div letter's pixel over. something like i <span> , set letter's color doesn't handle situation when single letter on both divs. anything do? (if possible i'd not down css chrome 47 , firefox 43 support). you can not without ugly hacky code. make 2 elements 2 texts overlapping each other hidden on other element. better explained example. check out jsfiddle. <div class="wrapper"> <div id="left"> <span>this long sentence test.</span> </div> <div id="right"> <span>this lo

i trying continuously consume events kafka. same application uses consumed data, perform analysis , update database in n-second intervals (assume n = 60 seconds). in same application, if process1 = kafka consumer , process2= data analysis , database update logic. process1 run continuously process2 executed once every n=60 seconds process2 concerned computation , database update , hence take 5-10 seconds execute. not want process1 stall during time process2 executing. hence, using multiprocessing module ( process1,process2 thread1,thread2 if using threading module in python due have read gil , threading module not being able leverage multi-core architecture, decided go multiprocessing module.) achieve concurrency in case. (if understanding of gil or threading module limitations mentioned above incorrect, apologies , please feel free correct me). the application have has simple interaction between 2 processes wherein process1 fills queue messages receives in 60 s

i decided move game windowed fullscreen mode , that's first problem face. i'm looking way of resizing of sprites based on screen resolution. background in (0, 0) coordinates, need have , sprites scale kind of fixed aspect ratio ( 16:9 preferred). , resize them portion background stretched fill screen. , not more, not less. i've looked online tutorials couldn't understand concept used. can explain how that? read using rendertarget2d , passing spritebatch.begin() call, has kind of effect, there's got more code. i'm not looking supporting resolution change option, adapting sprites current resolution. it sounds you're talking resolution independence . the general idea make game using virtual resolution , scale or down fit actual resolution of screen. var scalex = (float)actualwidth / virtualwidth; var scaley = (float)actualheight / virtualheight; var matrix = matrix.createscale(scalex, scaley, 1.0f); _spritebatch.begin(transformmatrix

in html code, have javascript. in order check whether code worked/became json object, first sent json object in blank html print out json. {"nodes": [{"id": "latin 2"}, {"id": "latin 2"}, {"id": "computer science 2"}, {"id": "calculus 2"}], "links": [{"id": 1, "target": "latin 1", "source": "latin 2"}, {"id": 2, "target": "latin 1", "source": "latin 2"}, {"id": 3, "target": "computer science 1", "source": "computer science 2"}, {"id": 4, "target": "calculus 1", "source": "calculus 2"}]} you can see did render json object, when wanted put json object in javascript, inside html, error code: {&#34;nodes&#34;: [{&#34;id&#34;: &#34;physics 5&#34;}, {&#34;id&a

let's have code: scanner scan=new scanner(system.in); char x = 'h', aux; system.out.println("insert single letter"); aux=scan.nextline().charat(0); if (x==aux)system.out.println("match"); is there way avoid scanner scannerobject = new scanner(); and work done function tool c's scanf() or fget()? confused this! you don't have use scanner input in java. scanner high level class parsing input while reading it. can read static inputsteam system.in . want wrap in bufferedreader though since want deal strings more byte arrays. e.g. bufferedreader br = new bufferedreader(new inputstreamreader(system.in)); string line = br.readline();

i have question on how anonymous functions work in javascript. saw beautiful piece of code toggle "disabled" html element [from post link stack overflow ]: $('#el').prop('disabled', function(i, v) { return !v; }); the inputs anonymous function , v index , value. why that? because of .prop() or somehow property of anonymous functions? there other inputs available? thanks solution: answer question in docs .prop() api.jquery.com/prop/ : it's how jquery .prop() method implemented. if sees second parameter function, calls function each matched element, passing element index , attribute value. inventing api in javascript involves making decisions situations involving callback api clients use. there no hard-and-fast rules in general, though contexts have conventions should followed when possible. example node world, it's common callbacks passed 2 arguments, (possibly null) error , data relevant operation.

i've been trouble shooting bad sql calls in works applications. i've been reading on indexes, tweaking , benchmarking things. here's of rules i've gathered (let me know if sounds right): for heavily used quires, boil down query needed , rework where statements use common columns first. make non clustered index on columns used in statement , including on remaining select columns (excluding large columns of course nvarchar(max) ). if query going return > 20% of entries table contents, it's best table scan , not use index order in index matters. have make sure structure statement index built. now 1 thing i'm having trouble finding info on if query selecting on columns not part of index using statement is? index used , leaf node hits table , looks @ associated row it? ex: table id col1 col2 col3 create index my_index on my_table (col1) select id, col1, col2, col3 my_table col1 >= 3 , col1 <= 6 is my_index used here? if so, how resolve

i understand how git merge happens. master & feature a--b--c --g--h--i --d--e--f here changes made , date when changed. g(master) - aug - 8th h(master) - aug - 10th i(master) - aug - 15th d(feature) - aug - 9th e(feature) - aug - 11th f(feature) - aug - 12th so, if merge master branch feature how history appear? merge based on date change , display this? feature branch a--b--c--g--d--h--e--f the way git merge creates if will, patch of diff between current branch , branch trying merge. applies patch whole branch commit - merge "source branch" "target branch" this new commit having. if want revert --d--e--f don't revert them individually, revert big merge commit. as time stamp, yes git give merge of commits in both branches can revert yourself. so imagine this, branch 1: - b - c - - g - h - branch 2: d - e - f merging these in branch 1 give - branch 1: - b - c - d - e - f - g - h - -
