this question has answer here: how bitwise nor gate in python (editing python maths work me) 2 answers i'm trying understand code answer received yesterday: 2nd: how make bitwise nor gate 1st: how bitwise nor gate in python (editing python maths work me) a=0b01100001 b=0b01100010 bin((a ^ 0b11111111) & (b ^ 0b11111111)) i understand except: the & between 2 values and ^ 11111111 ( know 0b base 2 ) can please explain these? how nor works? the expression x nor y can broken using and , or , , not : x nor y == not(x or y) == not(x) , not(y) so, given values: a=0b01100001 b=0b01100010 a nor b not(a) , not(b) . think how not(a) ? need flip bits. way flip bits? xor(^) . how? 0 ^ 1 == 1 1 ^ 1 == 0 so, taking xor of bit 1 flip bit. i.e. not(somebit) == xor somebit . so, in case, take xor of each bits in a , b 1 not

i cannot believe sounds simple can hard. class outputhandler { private: static std::string const errorprefixes[] = {"info", "warning", "error", "crash"}; }; how do properly? various documentations understand cannot initialize static member objects, regardless of them being constant. write initialization outside class, definition: class outputhandler { private: static std::string const errorprefixes[]; }; std::string const outputhandler::errorprefixes[] = {"info", "warning", "error", "crash"}; (the definition of course subject one-definition-rule , must appear in 1 single translation unit, e.g. outputhandler.cpp .)

i tried use gldepthfunc in opengl es 2.0 (at pc emulator) , don't understand behavior. in init function call define these values: glcleardepthf( 0.5f ); glclearcolor ( 1.0f, 0.0f, 0.0f, 0.0f ); and in drawing function code: glclear ( gl_color_buffer_bit | gl_depth_buffer_bit); glenable( gl_depth_test ); gldepthfunc(gl_lequal); gluniform4fv(unifcolor, 1, vercolor); gldrawarrays ( gl_triangle_fan, 0, 4 ); eglswapbuffers i'm drawing green square (half of screen size). when z value of drawn square 0.5. i expect depth test true , i'll see green square drawn, see red screen (the color used in clear color). when define clear depth value 1.0 receive expected behaviour: grren squar on red screen, think depth used needed (all initialzed defines depth). what can problem? thanks there things go wrong. there might precision issues. however, have guess here: i'm drawing green square (half of screen size). when z value of drawn square 0.5. wrrit

is there magento function value of "id" url: http://example.com/path/action/id/123 i know can split url on "/" value, i'd prefer single function. this doesn't work: $id = $this->getrequest()->getparam('id'); it works if use http://example.com/path/action?id=123 magento's default routing algorithm uses three part urls. http://example.com/front-name/controller-name/action-method so when call http://example.com/path/action/id/123 the word path front name, action controller name, , id action method. after these 3 methods, can use getparam grab key/value pair http://example.com/path/action/id/foo/123 //in controller var_dump($this->getrequest()->getparam('foo')); you may use getparams method grab array of parameters $this->getrequest()->getparams()

i need programmaticaly (c++) add kind of dns-resolving rule, redirect requests of specific domain localhost. there methods without modyfing etc/hosts file on windows? you install local dns server machine (for example: bind). change ip settings on machine use own local dns server (127.0.0.1) instead of normal dns servers. create new domain (with name of dns name redirected) on local dns server, , include address record in zone file of domain, specifying desired ip address (127.0.0.1). there 1 more step might neccessary: if machine cannot reach internet dns servers directly, through normal dns servers, have configure dns request forwarding local dns server, every domain request forwarded original dns servers.

( i'm not native english speaker, text may not natural ) i'm doing localization of asp.net project. efficiency of language translation, i'm extracting strings in .aspx global resource file. ( named resource file 'stringtable.resx'. ) in process, strings in aspx page changes follows : before : admin id after : <asp:literal runat="server" text="<%$ resources:stringtable, str_admin_id %>"> the 'after code' looks little bit long, want shorten code. ( example, remove runat="server" statement, remove resource name, etc... ) in c/c++ case, 1 can use #define macro. is there way in .aspx page? ( not in code behind file ) idea appreciated. ====== below own answer ======================================== i'm using vs2008, can't use <%: syntax in .net 4.0. and introduce alternative solution ( i'm not sure best solution ) first, added directive in upper portion of .aspx file.

with ios 7 apple suggest use uidatepicker , uipickerview inline within uitableviewcell showed here: ios 7 - how display date picker in place in table view? i have table view n rows dynamically allocated. each row represent object fetched core data. want display uipickerview below each row user tapped in let user select in range of values. i've thought adopt apple's way , insert uipickerview every 2 rows it's pretty weird , causes issues. how can 'follow' normal succession retrieving each object main nsarray _list contains each object fetched core data? is there 'better' way implement without having insert tons of uipickerview ? this image explains better, hope. take @ sample code linked to. don't insert picker every other row. there 1 picker appears below input row you're editing. picker appears during editing. after read code, maybe ask more specific question...?

i'm attempting error check determines whether the elements of array integers, i've been stuck long time though. ideas on how started helpful. scanner scan = new scanner(system.in); system.out.print("please list @ least 1 , 10 integers: "); string integers = scan.nextline(); string[] newarray = integers.split(""); using string made scanner, loop on space-delimited list , check each element integer. if pass, return true; otherwise return false. credit isinteger check goes determine if string integer in java public static boolean containsallintegers(string integers){ string[] newarray = integers.split(" "); //loop on array; if value isnt integer return false. (string integer : newarray){ if (!isinteger(integer)){ return false; } } return true; } public static boolean isinteger(string s) { try { integer.parseint(s); } catch(numberformatexception e) { return false; }

i adding new features old asp.net application uses n-tier architecture. basic example can given as object public class test { public int id{get;set;} public int name{get;set;} } data access layer public static list<test> gettests() { list<test> list = new list<test>(); try { //codes sqldatareader dr = com.executereader(); while(dr.read()) list.add(filltestrecord(dr)) //codes } catch{} return list; } private static test filltestrecord(idatarecord dr) { test test = new test(); try{test.id = convert.toint32(dr["id"]);} catch{} try{test.name = convert.toint32(dr["name"]);} catch{} return test; } the development requires me add new fields object classes , re-usability use 1 fill*record method each type of object. method can called many other dal methods idatarecord might not contain columns of object. hence put try-catch block every proper
