i inherited report generator creates xml file , formats using xsl/css. i'm not familiar web page creation. .html file created line of code: xslt.transform(xmlreader.create(xmlstream), writer); and displayed in .net 4.5.2 system.windows.controls.webbrowser object. report looks fine. renders nicely in ie 11, , not in firefox (some background colors missing). more importantly, though, user reporting problems converting .html .pdf using adobe acrobat (some images sized incorrectly) i'm investigating quality of .html formatting. opened .xml file created report generator in visual studio 2013 , flagged first 2 lines problems: <?xml:stylesheet type="text/xsl" href="mydir\report.xsl" ?> <?xml version="1.0"?> <myclass xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xmlns:xsd="http://www.w3.org/2001/xmlschema"> the first line flagged error: "invalid characters in processing instruction target&quo

when discussing endian, instructor gave word 0a0b0c0d in hexadecimal, , why 32-bit word? thanks. preamble: what answer have been had instructor given 000000000a0b0c0dh ? well, answers provided @ergonaut , @kdbanman yield 64-bits. your question: why 32-bit word? the value instructor gave not have 32-bit. considerd 64-bit, 128-bit, or else starting @ 28-bit matter. what important here the position of significant digit . find out translate hexadecimal value 0a0b0c0dh binary equivalent 0000' 1 010'0000'1011'0000'1100'0000'1101b , note 1 left occupies 28th position. remember bit numbering starts right! since 28 bits won't fit in 16-bit word, choose next higher format 32-bit. applying logic value in preamble lead 32-bit number correct answer. when classifying numbers don't consider leading zeroes!

i updating old ios app not support 64-bit architectures. from apple's conversion procedure, looks converts "int , unsigned int nsinteger , nsuinteger, respectively." however, when doing this, end lot of casting longs during formatting, shown below. concerned performance on 32-bit architectures because of of casting long. //old nsinteger myintvalue = 5; [nsstring stringwithformat:@"%d", myintvalue]; //new nsinteger myintvalue = 5; [nsstring stringwithformat:@"%ld", (long)myintvalue]; an alternative replace usages of nsinteger int, remain 4-byte values, not need cast long when formatting myintvalue. //old nsinteger myintvalue = 5; [nsstring stringwithformat:@"%d", myintvalue]; //new int myintvalue = 5; [nsstring stringwithformat:@"%d", myintvalue]; should latter method avoided particular reason, assuming items change nsinteger int guaranteed fit inside 4-byte int? those castings only way format strings when

i have large number of points in 3d space (x,y,z) represented array of 3 float structs. have access strong graphics card cuda capability. want following: divide points in array clusters every point within cluster has maximum euclidean distance of x @ least 1 other point within cluster. examle in 2d: the "brute force" way of doing of course calculate distance between every point , every other point, see if of distances below threshold x, , if mark points belonging same cluster. o(n²) algorithm. this can done in parallel in cuda ofcourse n² threads, there better way? the algorithm can reduced o(n) using binning : impose 3d grid spaced x, 3d lattice (each cell of lattice cubic bin); assign each points in space corresponding bin (the bin geometrically contains points); every time need evaluate distances 1 point, use points in bin of point , ones in 26 neighbouring bins (3x3x3 = 27) the points in other bins further x, don't need evaluate distances

i have number of tsv files, , want check each file correctly formatted. primarily, want check each row has right number of columns. there way this? i'd love command line solution if there one. awk '{print nf}' test | sort -nu | head -n 1 this gives lowest number of columns in file on given row. awk '{print nf}' test | sort -nu | tail -n 1 this gives highest number of columns in file on given row. result should same, if columns present. note: gives me error on os x, not on debian... maybe use gawk .

i change splash message of iron router failure .instead of "organize meteor application" ,add user friendly.how start issue ?? it hard coded here in iron:router repo. can fork , change line yours. but why need this? line 54 here can give idea of how iron:router uses templates. router.prototype.lookupnotfoundtemplate = function () { if (this.options.notfoundtemplate) return this.options.notfoundtemplate; return (this.routes.length === 0) ? no_routes_template : default_not_found_template; }; only if don't have routes defined , no config notfoundtemplate , see such message, define via router config. router.configure({ layouttemplate: 'layout', notfoundtemplate: 'pagenotfound' });
