following code returns true, why? var inputs = new object[]{null, 1}; var output = string.join(",", inputs); console.writeline(output == "");//prints true > output = "" but following code working fine var inputs = new object[]{"", null, 1}; var output = string.join(",", inputs); console.writeline(output == "");//prints false > output = ",,1" is wrong in native implementation? from msdn : if first element of values null , join(string, object[]) method not concatenate elements in values instead returns string.empty . which special case overload using object[] . note isn't true other overloads, string[] one.

i compiled net-snmp , copy installation package arm based linux. because file system small deleted commands binaries except snmpd , snmpget. then on arm board when tried "snmpget" got error "not found". have snmpget binary.

is there way raise warning or error if c++ compiler comes end of file without braces being closed? never use headers spill scope file , receive compiler warnings if happens accident. compiler msvc 2010, others might of interest too. // utilities.hpp namespace example { class utilities { } //<eof> -> should warn or error edit: willing put marker/pragma/macro @ end of each file, know brace level should 0. a reasonable method #define at_global_scope namespace { } because can appear @ global or namespace scope. unfortunately won't catch missing } namespace, catch class-case, missing parentheses , semicolons.

i've been trying write logic regarding exception handling evernote java api . stumbled upon weird situation. there 2 exceptions - edamsystemexception , edamuserexception ( documentation link ) both of exceptions have method edamerrorcode geterrorcode() lack common interface method. i feels flaw in api design, since state of codes make sense edamsystemexception , others edamuserexceptions since not state edamerrorcode bounds exception, , shielding myself situation of codes use in both of exception types wanted write try-catch block: try { clientfactory.createnotestoreclient(); } catch (edamsystemexception | edamuserexception ex) { switch (ex.geterrorcode()) { case invalid_auth: case bad_data_format: .. case auth_expired: ... case rate_limit_reached: ... default: ... } } catch (texception ex) { ... } but (obviously) cannot call ex.geterrorcode() . instance checki

i've read swift docs on optional binding it's incomprehensible me @ level of knowledge (and/or intelligence). what's difference between: var number:int? = 1 if let num = number { print("number \(number!)" } else { print("it must nil") } and var number:int? = 1 if number==nil { print("it must nil") } else { print("number \(number!)" } as far can tell, these work same, , @ least me second 1 more readable. , wouldn't ordinarily care this, if let prominent in basic tutorials it's useful, i'd know why. suppose had 2 optional values , b classic syntax if != nil { if a?.b != nil { here access a.b.blah } } new syntax if let blah=a?.b?.blah { use blah ... } it's shorter,more readable , more flexible

how define function name (in php) using variable, this? $a='blabla'; function {$a}() {.......} or that? the way know give fixed name function use eval, not suggest. more likely, want stuff function in variable, , call that. try this: $a = function() { echo 'this called anonymous function.'; } $a(); edit : if want accessible other files, use global variable: $globals['variable_name'] = 'my_func_123'; ${$globals['variable_name']} = function() { echo 'this called anonymous function.'; }; // executing my_func_123() ${$globals['variable_name']}(); see also: http://php.net/manual/en/functions.anonymous.php

i have python 2 code, works alright: # python 2 key = 'l\x1e@\xael\xc0\xa9\xa3\x8d\x9e5\xac\x00\xe5\x98h' # type(key) => <type 'str'> originally key random 32bytes value. , here share repr() values. so can use random bytes-like sequence string. when comes python3, incoming string in bytes: # python 3 key = b'l\x1e@\xael\xc0\xa9\xa3\x8d\x9e5\xac\x00\xe5\x98h' # type(key) => <class 'bytes'> and need convert string "as looks", without replacing characters. i tried though ascii: key_chuncks = [chr(s) s in key] # ['l', '\x1e', '@', '®', 'l', 'À', '©', '£', '\x8d', '\x9e', '5', '¬', '\x00', 'å', '\x98', 'h'] as see chr(s) interpretes bytes sequences characters , don't need behavior. there way, convert bytes string "as looks"? without character interpretation (decoding).

i optimising queries , found can't head around. i using following query select bunch of categories, combining them alias table containing old , new aliases categories: select `c`.`id` `category.id`, (select `alias` `aliases` category_id = c.id , `old` = 0 , `lang_id` = 1 order `id` desc limit 1) `category.alias` (`categories` c) `c`.`status` = 1 , `c`.`parent_id` = '11'; there 2 categories value of 11 parent_id , should 2 categories alias table. still if use explain says has process 48 rows. alias table contains 1 entry per category (in case, can more). indexed , if understand correctly therefore should find correct alias immediately. now here's weird thing. when don't compare aliases categories conditions, manually category ids query returns, process 1 row, intended index. so replace where category_id = c.id where category_id in (37, 43) , query gets faster: the thing can think of subquery isn't run on r
