oftentimes, have problem property can either true or false, property b either true or false, , on. want test every combination of being true while b being false, , on. example might need following list: [true,true,true] [true,true,false] [true,false,true] [true,false,false] [false,true,true] [false,true,false] [false,false,true] [false,false,false] in haskell or python, can done list product function. my question is, what's simplest and/or quickest way generate this? have done converting number binary, converting binary array. seems cumbersome because decimal binary conversion isn't trivial, , need worry padding binary leading zeroes fill array properly. i have implemented , re-implemented kind of function in different contexts enough times wonder, there way simple enough can implement scratch when necessary -- without having think? i'm not sure of code along these lines should work. for( int = 0; < 8; i++ ){ printf( "[%s, %s, %s]\n", (

in mfc vc++ , settimer function setted using callback procedure. link read a function marked __stdcall uses standard calling convention named because win32 api functions (except few take variable arguments) use it. and that, have understand, vc++ mfc functions use __stdcall calling conversions. and callback defined follows.... #define callback __stdcall what have read: preceding function callback used emphasise particular function called automatically whenever necessary(like in settimer case or onclick case in javascript), my doubt is , in mfc vc++ functions(except few take variable arguments) has default calling convention of __stdcall. hence either preceding or not preceding function callback or winapi or pascal has same effect? is absolutely necessary computer? depends on context. when mismatch calling convention , either lucky because datatypes on stack happen match requirements of api, or fail miserably when code run on different a

how can find width , height of rectangle drawn function cvrectangle following parameters? cvrectangle( input1, cvpoint(200,178), cvpoint(190,110),color ,1, 8 ); you set parameters, calculating width , height should trivial, shouldn't it? width = (200-190) , height = (178-110) . but, @bubble suggests, since you're dealing pixels, don't forget add 1, resulting in (200 - 190) + 1 width , (178 - 110) + 1 height. or expect cvrectangle give rectangle "object" can these values from? doesn't.

i'm trying emmulate following: any ideas how? photos have same height , photos arrange/cropped/resized dynamically fit on rows there no jagged sides left or right. if resize browser window resizes photos fit. have tried isotope , jquery masonry , neither give me effect. i implemented thing. here's how did it: when page loads, measure available width of target container (the container images live), , call maxwidth i make ajax call, passing maxwidth server i determine list of gallery images display on server, , process each 1 one during iteration of list, keep adding images row, row's length being maxwidth available (which passed up). once image overflows maxwidth, calculate overflow amount i take overflow amount, divide number of images in row, , subtract value off each of images in row (so 1 image doesn't width reduced much) i repeat each row, each row adds maxwidth some things had consider: i had take account width of margins wanted in b

i trying understand indexing conventions of image processing type functions, in opencv. so indexing pixel [row, column] i.e. y,x, right? think pretty common in image processing. but when picking points rectangle in opencv requires [col, row] i.e. x,y. , true function wants cvpoint so if writing function say, takes sample coordinate in image, should [col, row] or [row, col] ? internally image almost stored in rows - index naturally [row,column] but in maths x,y more common function asks individual pixel coordinate better f(x,y) opencv confuses matters creating images call specifies image (rows,cols) ie. image(height,width) nam image cols-rows ie 640x480 or 1920x1080

the famous ttfb confusing me. what describes it, first byte of http response or first byte of underlying protocols tcp? you can read gzipping content lower ttfb, why? zipping means more cpu load on server side should result in worse ttfb or wrong here? the time of "flushing" content seems important, have trouble finding more information on it. how can influence flushing, e.g. on php based webpage? simple setting/configuration of server or location in code perform "echos" ? thank you ttfb delay between end of request , receiving response, we're talking web here when browser received first byte. gzipping content increase ttfb provided server isn't overwhelmed should negligible delay. what gzipping reduce overall time download content. normally server won't send page browser until whole page has been generated, flushing return content browser can process , start downloading , files referenced sooner. a explanation of flushing st

this facebook interview question came across @ online portal. given set s, find maximal subsets sum <= k. example, if s = {1, 2, 3, 4, 5} , k = 7 output is: {1, 2, 3} {1, 2, 4} {1, 5} {2, 5} {3, 4} hints: output doesn't contain set subset of other. if x = {1, 2, 3} 1 of solution subsets of x {1} {2} {3} {1, 2} {1, 3} {2, 3} omitted. lexicographic ordering may used solve it. any ideas how solved? i have idea - need tree. if have given input of {1, 2, 3, 4, 5} , , you're searching maximal subsets - should build tree starting biggest numbers, , allways expand while sum <= k (so don't stop on 4-2, go down 1 4-2-1). so, nodes starting 5 be: 5-1 / 5-2 - 2 have sum <= 7 starting 4: 4-3 / 4-2-1 / 4-1 (subset of previous) starting 3: 3-2-1 / 3-1 (subset of previous) starting 2: 2-1 (subset of 3-2-1) starting 1: 1 (subset of 2-1) then can sort valid outputs , {1, 2, 3} {1, 2, 4} {1, 5} {2, 5} {3, 4}

is solution in jqgrid if there negative number show bracket "()" ? ex: show (23) if value -23 thanks you can use custom formatter want. format numbers or integers correctly can call $.fmatter.util.numberformat method $.jgrid.formatter.number or $.jgrid.formatter.integer second parameter. example of formetter is formatter: function (cellvalue, options) { var value = parsefloat(cellvalue), retult, op = $.extend({}, $.jgrid.formatter.number); // or $.jgrid.formatter.integer if(!$.fmatter.isundefined(options.colmodel.formatoptions)) { op = $.extend({}, op,options.colmodel.formatoptions); } retult = $.fmatter.util.numberformat(math.abs(value), op); return (value >= 0 ? retult : '(' + retult + ')') + ' €'; } you can additionally change color or other css style of displaying of negative numbers. can use cellattr property add class or style attribute in cells negative numbers: cellattr:
