i'm working on vba code writes formulas containing user-defined functions (udfs) cells of workbook, e.g.: h1004 = maxdd(h1:h1001) . when run code in excel 2010 (for windows) works expected: 1) formulas written cells 2) each cell returns correct result. when run same code in excel 2011 mac formulas written cells. however, cells won't return valid results - instead display #value errors. note: can't troubleshoot issue because when select 1 of these cells, put cursor in formula field, , press return (presumably forcing cell evaluate), correct answer appears. my question: what needs done keep excel mac returning #value errors instead of plain results? i figured out what caused problem, although have no idea why caused problem: in order make vba code run faster, had turned off automatic calculation @ beginning of code , turned on @ end of code, --> application.calculation = xlcalculationmanual 'main part of vba code ...

assume hacker obtains data set of stored hashes, salts, pepper, , algorithm , has access unlimited computing resources. wish determine max hash size certainty of determining original input string nominally equal target certainty percentage. constraints: the input string limited 8 numeric characters uniformly distributed. there no inter-digit relation such checksum digit. the target nominal certainty percentage 1%. assume hashing function uniform. what maximum hash size in bytes there nominally 100 (i.e. 1% certainty) 8-digit values compute same hash? should possible generalize n numerical digits , x% accepted answer. please include whether there issues using first n bytes of standard 20 byte sha1 acceptable implementation. it recognized this approach increase susceptibility brute force attack increasing possible "correct" answers there design trade off , additional measures may required (time delays, multiple validation stages, etc). ...

i've converted mysql db postgres . i'm used following import db: heroku pgbackups:restore database 'http://app.com' --app this creates tables , imports data. the problem have following: heroku run rake db:seed --app then list of pending migrations. is there way ignore these, reset it, or doing wrong? thank you

i have testing search software , stores data in multidimensional array. can return whole database cannot return 1 value. i'm trying figure out how return 1 section multidimensional array. otherwise repeats passed value across display. while de-bugging can see complete array stored argument having trouble figuring out how loop through array display correctly. may need view source understand better. if enter lets 439023483 , click search isbn button, see issue. show button works fine. pointing me in right direction appreciated , thank in advance. here link testing source: http://mdhmotors.com/jstesting/test.html here part of code i'm stuck on: function searchbyisbn(isbn) { var isbn = document.getelementbyid('isbn').value; showbooks(getbookbyisbn(isbn)); } function getbookbyisbn(isbn) { var foundbook = null; (b in bookstore) { var book = bookstore[b]; if (book[isbn] == isbn) { foundbook = new array(book[isbn], book[title...

well, haven't found clean solution write code in ruby: # java style version: array.each |i, el| if < array.length - 1 process(array[i], array[i+1]) end end # nice if this: array.each |i, el, next| process(el, next) end you can use each_cons : array.each_cons(2) |a, b| process(a, b) end

i ask if possible override log methods or create new 1 properties in method. at moment can use it: globalcontext.properites["details"] = "some info"; log.error("some info",exception); i use it: log.myspecialerror(details, message, exception); any advice appreciated ori create own extension method. it must defined in static class, , static method. e.g. definitions: public static class log4netextensions { public static void myspecialerror(this log log, string details, string message, exception exception) { //do parameters } } use: log.myspecialerror(details, message, ex);

i trying debug problem. i've gone great extremes , trying figure out why mysql return null when return var explicitly set value. delimiter $$ create definer=`root`@`localhost` procedure `foo`( out numberexpectedtofill int(11)) deterministic begin set numberexpectedtofill := 23; commit; end so, scripted little script call it, , return value null. why? prepare s 'call `test_schema`.`foo`(@output)'; execute s; select @output this unexpected ... works in sqlfiddle both , without using prepared statement: http://sqlfiddle.com/#!2/d4ddf/1 , http://sqlfiddle.com/#!2/d4ddf/2 maybe there problem permissions (would signal error, thought) ?!? edit: still guessing -- sure call foo right schema? o_o

i've searched few topics i'm still stuck, i'm new c# , error starting give me headache. i'm trying initilise list keep getting error message. welcome. public static list<bookoperator> createbookoperators() { list<bookoperator> ops = new list<bookoperator>(); bookoperator op = new bookoperator(ops); ops.add(op); return ops; } it looks me there no reason try , pass list book-operator. money says: public static list<bookoperator> createbookoperators() { list<bookoperator> ops = new list<bookoperator>(); bookoperator op = new bookoperator(); ops.add(op); return ops; } or more tersely: public static list<bookoperator> createbookoperators() { return new list<bookoperator> { new bookoperator() }; }

this followup question here: updating child association in activemodel i'm looking standard/correct way update number of children records associated parent. lets have parent (connected child table has_many, , :autosave=>true). obj = parent.first now iterate on children, , update them. obj.each.do |child| child.remark = "something" end i children saved parent, when calling obj.save, explained me in previous question, way update directly, this: obj.children.first.remark = "something" (or save each child, require explicit transaction believe shouldn't used here). what correct way implement this? thanks! *edit : following advice given here, i've added model: class parent < activerecord::base has_many :children, :inverse_of => :parent,:autosave=>true accepts_nested_attributes_for :children but still, x = parent.first c = x.children.first c.remark = "something" x.save # => doesn't...

when page webview first loads, images missing or displayed incorrectly. if reload page webview displays perfectly. know first think set javascript after loadurl, isn't true. in oncreate have: learnwebview = (webview)findviewbyid(r.id.learnwebview); learnwebview.setwebviewclient(new webviewclient()); learnwebview.getsettings().setjavascriptenabled(true); then later in function called after oncreate have: learnwebview.loadurl("myurl"); and yes, know function loadurl called after oncreate every time. please try instead of way, bad practice: learnwebview.post(new runnable() { @override public void run() { learnwebview.loadurl("myurl"); } }); or this, in case first 1 wont work: learnwebview.postdelayed(new runnable() { @override public void run() { learnwebview.loadurl("myurl"); } }, 500); h...

i capturing color , depth images kinect windows using matlab , official kinect sdk. both sensors synchronized such image each sensor of same moment. unfortunately, current implementation has lag between 2 sensors (of 1 second!). please me find way synchronize sensors. here current code: colorvid = videoinput('kinect',1,'rgb_640x480'); depthvid = videoinput('kinect',2,'depth_640x480'); triggerconfig([colorvid depthvid],'manual'); set([colorvid depthvid], 'framespertrigger', 300); start([colorvid depthvid]); trigger([colorvid depthvid]); pause(10); [imgcolor, ts_color, metadata_color] = getdata(colorvid); [imgdepth, ts_depth, metadata_depth] = getdata(depthvid); stop([colorvid depthvid]); delete([colorvid depthvid]); clear colorvid depthvid; i've played while , seems adding pause between start() , trigger() functions solves problem! start([colorvid depthvid],'framespertrigger',300); pause(1); trigger([colorvid d...
