i using nsfetchedresultscontroller display objects event in list. event -object has property of startdate , eventtype property enum of types checkin , concert , meeting , flight , checkout . nsfetchedresultscontroller has sortdescriptor orders events startdate : eventsrequest.sortdescriptors = [nssortdescriptor(key: "startdate", ascending: true)] this works fine, however, in cases startdate checkin event , meeting event same. confuses sortdescriptor , places meeting before checkin . is possible make custom nssortdescriptor checks if startdate same, checks eventtype property , returns checkin before meeting ? sortdescriptors array, add additional nssortdescriptor second property wish, that: eventsrequest.sortdescriptors = [nssortdescriptor(key: "startdate", ascending: true), nssortdescriptor(key: "eventtype", ascending: true)] this firstly use nssortdescriptor startdate , if same check value of eventtype

i know that when synchronize block of code, specify object's lock want use lock, could, example, use third-party object lock piece of code. gives ability have more 1 lock code synchronization within single object. however, don't understand need of passing argument block. because doesn't matter whether pass string's instance, random class's instance synchronized block synchronized block works irrespective of parameter being passed block. so question if anyways synchronized block stops 2 threads entering critical section simultaneously. why there need of passing argument. (i mean acquire lock on random object default). i hope framed question correctly. i have tried following example random parameters being synchronized block. public class launcher { public static void main(string[] args) { accountoperations accops=new accountoperations(); thread lucy=new thread(accops,"lucy"); thread sam=new thread(ac...

i'm working on application using static variables (eg: pixel width of tile, or how many tiles want in array). i have them declared in class defines object, example tilewidth in tileclass. using width in multiple other classes, , bugged fact have import whole tile class access field. there performance loss this? is better practice hold static variables (they constants) in separate class , import whenever need variable? is there other better way using static variables? thanks is better practice hold static variables (they constants) in separate class , import whenever need variable? just put constants in interface , reference them using interface. there no performance impact such put design rather creating class constants , making them public static (as variables defines in interface implicitly public default , static ).

i think found bug not 100% sure if 1 or doing wrong. setting timezone this: inside application.rb ... config.i18n.default_locale = :en config.time_zone = 'melbourne' config.active_record.default_timezone = 'melbourne' ... when updating model timestamp columns ( created_at , updated_at ) doesn't update them. problem caused line config.active_record.default_timezone = 'melbourne' (when remove it, works fine). query seems fine when reload model timestamps nil. think problem appears in datetime columns , doesn't matter database using (i managed reproduce in postgres , in sqlite). is expect because forgot configure or bug? config.active_record.default_timezone accepts 2 values: :local :utc what can set: config.time_zone = 'melbourne' and config.active_record.default_timezone = :local will trick.

i put actual logic symbols emacs buffers, e.g., logic symbol "∀" or "∃" or "⇒", directly (fundamental) text or .org or whatever buffer. found xmsi-math-symbols-input.el @ ergoemacs , i'm wondering if "best practice." maybe best practice right tex/latex copy, if i'm doing org-mode? you can use corresponding unicode characters in emacs. bind want keys want. example: (global-set-key [f2] "∀") (global-set-key [f3] "∃") (global-set-key [f4] "⇒") to string char, can use c-x 8 ret , type name or code point of unicode char. in other words, c-x 8 ret lets insert unicode character. for example, unicode code point ∀ 2200. c-x 8 ret 2200 ret inserts ∀ character. and unicode name of ∀ for all . c-x 8 ret ret inserts ∀ character. the reason might want bind particular character key convenience - c-x 8 ret general, , slow.

probably stupid question here started programming in android bear me. https://gist.github.com/gabrielemariotti/ca2d0a9f79b902b19a65 i'm following project implement gridviewpager on android wear application. works fine, background images i'm trying use not displaying. displays black screen. the issue getbackground() method, imagereference in particular. public imagereference getbackground(int row, int col) { simplepage page = ((simplerow)mpages.get(row)).getpages(col); return imagereference.fordrawable(page.mbackgroundid); } the tutorial shows image reference should returned getting build errors saying imagereference cannot resolved. have create class or interface imagereference? or set attribute on images themselves? can shed light on this? cheers in advance. as of version 1.1 of wearable support library (which fragmentgridpageradapter part of), methods have changed quite bit: no longer use sort of imagereference class -...

so basically int num = rand(2); //random number 0-2 int othernum, otherothernum; othernum = implement otherothernum = implement for example, if num 2, othernum , otherothernum must set 0 , 1 (or 1 , 0). how implement this? assume can't use branching or tables. yes i'd bit manipulation solution. yes i'd solution faster solution uses modulus operator (as essentialy division). i think lookup might fastest not sure, dont solution though. you can xor , bit masking. #include <stdio.h> void f(unsigned val, unsigned ary[3]) { ary[0] = val; ary[1] = (ary[0] ^ 1) & 1; ary[2] = (ary[0] ^ 2) & 2; } int main() { unsigned ary[3] = {0}; f(0, ary); printf("f(0) = %d %d %d\n", ary[0], ary[1], ary[2]); f(1, ary); printf("f(1) = %d %d %d\n", ary[0], ary[1], ary[2]); f(2, ary); printf("f(2) = %d %d %d\n", ary[0], ary[1], ary[2]); return 0; } this print: f(0) = 0 1 2 f(1) = 1...

i looking way specify output format without using label. to understand mean, label: write(*,1001) icount, x, y 1001 format (i5,f5.2,e12.3) without label should put format (i5,f5.2,e12.3) somewhere in write statement, write(*,format(i5,f5.2,e12.3)) icount, x, y i think saw somewhere unfortunately cannot find again. if exists feature of newer fortran version. maybe fortran 90? maybe fortran 2008? try write(*,'(i5,f5.2,e12.3)') icount, x, y

the dart <object> element not support getter access <object>.contentdocument , thought extending object add functionality. i took @ implementation of objectelement , need add these lines: @domname('htmlobjectelement.contentdocument') @docseditable() document contentdocument => _blink.blinkhtmlobjectelement.instance.contentdocument_getter_(this); however, have no idea how this. solution using @ time proxy redirects calls underlying jsobject honest, not dirty, impossible maintain. /* updated explain root of evil */ when starting project working on, wanted display svgs, uploaded user, on website , let user manipulate these svgs inserting additional svgelements or removing others. when downloading svgs string , displaying them by container.append(new svgelement(svgcode)) i got strange display bugs such embeded images in svgs displaced or removed , other bugs masks. the problem solved using <object> tag , set setting data attribute ...

i have fixed header , when resize browser window logo on header resizes , want change margin of logo when image resized how do that? this jquery use resize image $(window).on('load resize', function() { var maxsize = 2560; var screenwidth = $(this).width(); var factor = 0.27*screenwidth-(maxsize-screenwidth)*0.05; if (factor > 2560) factor = 2560; $('#logo').css('width', factor) }); }); css: #logo{ margin-top:5px; margin-left:10px; float:left; cursor: pointer; display:block; min-width:220px; height: auto; width: auto\9; /* ie8 */ }

i want write method compare 2 byte arrays, not want use these solutions because want method resistant timing attacks. method looks like: static bool areequal(byte[] a1, byte[] a2) { bool result = true; (int = 0; < a1.length; ++i) { if (a1[i] != a2[i]) result = false; } return result; } (with assumption a1 , a2 have same length). my concern sufficiently smart just-in-time compiler might optimize returning if result ever set false. i have checked jitted assembly code produced .net 4.0.30319, , not: ; `bool result = true;' 00e000d1 bb01000000 mov ebx,1 ; `int = 0;' 00e000d6 33f6 xor esi,esi ; store `a1.length' in eax , @ dword ptr [ebp-10h] 00e000d8 8b4104 mov eax,dword ptr [ecx+4] 00e000db 8945f0 mov dword ptr [ebp-10h],eax ; if `a1.length' 0, jump `return resu...
