i'm interested in moving away xcode , manually compiling metal shaders in project mixed-language application. i have no idea how this, though. xcode hides details of shader compilation , subsequent loading application @ runtime (you call device.newdefaultlibrary() ). possible, or have use runtime shader compilation purposes? generally, have 3 ways load shader library in metal: use runtime shader compilation shader source code via mtldevice newlibrarywithsource:options:error: or newlibrarywithsource:options:completionhandler: methods. although purists may shy away runtime compilation, option has minimal practical overhead, , viable. primary practical reason avoiding option might avoid making shader source code available part of application, protect ip. load compiled binary libraries using mtllibrary newlibrarywithfile:error: or newlibrarywithdata:error: methods. follow instructions in using command line utilities build library create these individual binary l...

i make vertical bar chart ( http://bl.ocks.org/mbostock/3886208 ) horizontal bar chart. thanks help! code examples nice. it's matter of reversing domains, axis , rect calculations: var y = d3.scale.ordinal() .rangeroundbands([height, 0], .1); // y becomes ordinal var x = d3.scale.linear() .rangeround([0, width]); // x becomes linear // change state group positioned in y instead of x var state = svg.selectall(".state") .data(data) .enter().append("g") .attr("class", "g") .attr("transform", function(d) { return "translate(0," + y(d.state) + ")"; }); // rect calculations become state.selectall("rect") .data(function(d) { return d.ages; }) .enter().append("rect") .attr("height", y.rangeband()) // height in rangeband .attr("x", function(d) { return x(d.y0); }) // horizontal position in stack .attr("w...

i want remove digit/non character @ farthest distance remaining characters in binary image. renaming characters , digits have fixed distance. in image: i want remove "5" , in image: i want remove non-characters. i want when image have 2 rows (like image1 , image2). in single row image don't want anything. couldn't quite figure out mark doing, decided create own method. if have statistics toolbox, i'd apply kmeans clustering of centroids of characters , remove centroid has least amount of characters - namely isolated island 1 character. given first image, had pre-processing remove green bounding box surrounded each character. when read in image stackoverflow, had associated colour map , read in indexed image. had convert indexed image colour image, extracted out green channel light green bounding box removed.

is there way in android programming know when person carrying android device has moved left/right [more shifting right/left] in reference last known position? for example: if held android device left of me, moving right, app should tell me relative last position of device, has moved right. there 2 different ways of doing this, maybe more. you use compass find direction phone pointing @ start , end, , accelerometer tell way moved. similarly use gps coordinates in lieu of accelerometer. both of these methods might give false positives or might not pick up- first 1 you'd have false positives dues jerky movement (you'd have employ filtering or data useless) while second have issues there resolution of gps not tight enough (say within 10 feet of starting point). gps doesn't work indoors. some devices won't have combination of sensors need. if more specific conditions , environment might able edit give better answer.

why recursive countoccurence function not working? has subroutine. there way without subroutine? seems in javascript have have closure (subroutine function) counter variable, otherwise gets rewritten every time! function numoccurencesrecursive(arr, val) { //base case. check if has length of 1 var count = 0; function docount(arr, val) { if (arr[0] === val) { count++; } else { count += docount(arr.slice(1), val) } return count; } return docount(arr, val); } console.log(numoccurencesrecursive([2, 7, 4, 4, 1, 4], 4)); // should return 3 returns 1 i think problem thinking iteratively used recursive approach. the iterative approach has global variable may updated @ each step: function numoccurencesiterative(arr, val) { var count = 0; for(var i=0; i<arr.length; ++i) if(arr[i] === val) ++count; return count; } however, when using recursive approaches, better avoid global variables. function numoccurencesrecursive(arr, val...

say there matrix of (m x n x p), esp. color image r g , b channel. each channel information 8-bit integer. but, analysis, 3 8-bit values have combined 24-bit value , analysis done on (m x n) matrix of 24-bit values. after analysis, matrix has decomposed 3 8-bit channels displaying results. what doing right now: iterating through values in matrix convert each decimal value binary (using dec2bin ) combine 3 binary values 24-bit number (using strcat , bin2dec ) code: i=1:m j=1:n new_img(i,j) = bin2dec(strcat(... sprintf('%.8d',str2double(dec2bin(img(i,j,1)))), ... sprintf('%.8d',str2double(dec2bin(img(i,j,2)))), ... sprintf('%.8d',str2double(dec2bin(img(i,j,3)))))); end end for decomposition 3 8-bits after analysis, exact reverse process done, still iterating through (m x n) values. the problem huge computation time. i know not correct way of doing this. ...
