say have following: template <class t> class foo {}; and descendant class, class bar : public foo<some_typename>{}; how go passing bar foo's constructor without foo.h including bar.h, if possible? it's unusual, there ways around it, depending on needs (elaborate, perhaps?). understand makes sense pass bar foo. in case, could: 1) create second template parameter in foo , lay out interface required @ construction: template < typename t, typename bar_ > class foo { /* ... */ foo(bar_& bar) : weight_(bar.getweight()) { } /* ... */ 2) or use template ctor: template < typename bar_ > foo(bar_& bar) : weight_(bar.getweight()) { } 3) if foo+bar lightweight, create extended initialization list, used bar @ init. 4) since template (and implementation must visible subclass , has special linkage), declare foo ctor takes bar pointer, define foo constructor in bar.hpp

while interview , confused after interviewer asked question global assembly cache (gac). should answer? question 1: instead of keeping assembly in gac, if create directory , keep our assemblies there , if make directory shared can connected computers can use assemblies? difference if kept assembly in gac , in shared folder ? edited: question 2: consider there 4 visual studio enabled development machines. out of , one serve server . can other machines (other server machines) use assemblies in gac of server machine ? the assemblies hosted in gac, formally called shared assemblies or global assemblies (please don't confuse shared assemblies). 1 advantage of placing assembly in gac version control, while assembly in gac, can co-exist version of same assembly, although have same file name, distinguished internal signature, contains strong name. please see link

given std::map<int,std::string> mymap; fillmymapwithstuff(mymap); // modify key values - need add constant value each key (std::map<int,std::string>::iterator mi=mymap.begin(); mi != mymap.end(); ++mi) { // ... } whats way apply re-indexing? must remove old entry , add new 1 new key , old value? looks better off building new map , swapping afterward. you'll have n insert operations instead of n deletions , n insertions.

i wrote function add listitem text box , remove button, everytime add button clicked. i'm adding unique id each new element adding number. problem happens when try remove element, add one, number being duplicated. ex: add 4 li's , decide remove #3. click add new again new sequence 1,2,4,3,4 instead of 1,2,4,5,6. hope made sense. here javascript var count = 2; $('#add').click(function() { var newtxtbxli = $('<li></li>').attr('id', 'newli' + count).appendto('ul'); var input = $('<input type="text" id="newinput' + count + '" name="newinput' + count + '" /><input type="button" id="remove' + count + '" class="remove" value="">'); $(input).appendto(newtxtbxli); count++; $('.remove').each(function() { $(this).click(function() { //count--; $(this)....

how concatenate arrays of aliases in perl such resulting array contains aliases? the solution came is: my ($x, $y, $z) = 1 .. 3; $a1 = sub {\@_}->($x); $a2 = sub {\@_}->($y, $z); $a3 = sub {\@_}->(@$a1, @$a2); "@$a3"; # 1 2 3 $_++ $x, $y, $z; "@$a3"; # 2 3 4 what not crazy create $a3 have unpack $a1 , $a2 . short arrays isn't problem, data grows larger, means array operations on aliased arrays o(n) , including traditionally o(1) operations push or unshift . data::alias help, doesn't work latest versions of perl. array::refelem contains wrappers around api primitives av_store , av_push can used implement functionality. work: sub alias_push (\@@) { if (eval {require array::refelem}) { &array::refelem::av_push($_[0], $_) @_[1 .. $#_] } else { $_[0] = sub {\@_}->(@{$_[0]}, @_[1 .. $#_]) } } i interested know if there other ways. particularly if there other ways using core modules. ...

i have sworn worked differently in previous versions of ios, of ios 4.0 looks app's keychain items not removed when app removed. however, looks cleared when app upgraded without first removing? can provide clear explanation of when ios keychain items removed? as answered here , , somewhere else (i can't remember read it), keychain persist after app removed. positive keychain isn't cleared unless explicitly delete item in it.

i trying split string array of word pairs in php. example if have input string: "split string word pairs please" the output array should like array ( [0] => split [1] => string [2] => string [3] => word [4] => word pairs [5] => pairs please [6] => please ) some failed attempts include: $array = preg_split('/\w+\s+\w+/', $string); which gives me empty array, and preg_match('/\w+\s+\w+/', $string, $array); which splits string word pairs doesn't repeat word. there easy way this? thanks. why not use explode ? $str = "split string word pairs please"; $arr = explode(' ',$str); $result = array(); for($i=0;$i<count($arr)-1;$i++) { $result[] = $arr[$i].' '.$arr[$i+1]; } $result[] = $arr[$i]; working link

i playing bit eric lippert's ref<t> class here . noticed in il looked both anonymous methods using same generated class, though meant class had variable. while using 1 new class definition seems reasonable, strikes me odd 1 instance of <>c__displayclass2 created. seems imply both instances of ref<t> referencing same <>c__displayclass2 doesn't mean y cannot collected until vart1 collected, may happen later after joik returns? after all, there no guarantee idiot won't write function (directly in il) directly accesses y through vart1 aftrer joik returns. maybe done reflection instead of via crazy il. sealed class ref<t> { public delegate t func<t>(); private readonly func<t> getter; public ref(func<t> getter) { this.getter = getter; } public t value { { return getter(); } } } static ref<int> joik() { int[] y = new int[50000]; int x = 5; ref<int> vart1 ...

i tried package django app today. it's big baby, , setup file, have manually write packages , sub packages in 'package' parameter. have find way copy fixtures, htmls / css / image files, documentations, etc. it's terrible way work. computer scientists, automatize, doing makes no sense. and when change app structure ? have rewrite setup.py. is there better way ? tool automate ? can't believe language value developer time python makes packaging such chore. i want able install app using simple pip install. know build out, it's not simpler, , not pip friendly. at least if use setuptools (an alternative stdlib's distutils ) awesome function called find_packages() when ran package root returns list of package names in dot-notation suitable packages parameter. here example: # setup.py setuptools import find_packages, setup setup( #... packages=find_packages(exclude='tests'), #... ) p.s. packaging sucks in every l...

i've been trying use slidedown() effect website i'm working on, i'm having difficulty getting effect want. here's sample showing want accomplish. <div> blahblahblahblah <span id="span_more" style="display:none"> blahblahblah </span> <a class="link_more" id="more">more&hellip;</a></div> </div> basically, when "more..." clicked, want text that's hidden appear using sliding effect while staying inline end of visible text. doesn't seem possible slidedown() because changing display block. thank much. unfortunately, impossible. jquery's animation relies upon element having height , width. inline elements not have these dimensions set or settable, animations (whether using animate or slideup ) must make them block-level elements. fadein work, , may useful alternative.

i've read php section on http://projects.webappsec.org/null-byte-injection . the example provides pretty dumb - mean, why ever want include file based on outside param without checking first (for directory traversal attacks, one)? so, if following standard php security practices, such as encoding user entered data on display validating user entered stuff works files preventing crsf not running uploads via executes php etc can provide real life example or common mistake of php developers problem can occur? thanks upate i'm trying make break, , have tried . // $filename public $filename = "some_file\0_that_is_bad.jpg"; $ext = pathinfo($filename, pathinfo_extension); var_dump($filename, $ext); which outputs string(26) "some_file�_that_is_bad.jpg" string(3) "jpg" i believe part of fun null byte injection simple validation may not enough catch them e.g. string "password.txt\0blah.jpg" ends ".jpg...

why commands require echo statement others can written without: #!/bin/bash aptitude upgrade echo "mysql-server-5.1 mysql-server/root_password password $db_password" | debconf-set-selections the commands feed on stdin input process, fed echo command. echo dumps string provided on stdout, in turn duplicated on stdin using pipe "|". commands not require input stdin or uses other method of input process can written without echo command.

i having json collection fetched mongodb & want convert hash. how can so..? thanks in advance.. how did fetch mongo? ruby mongo driver automatically gives ruby hashes. edit: take second question account in mongo, queries don't execute until call requires them execute. before call to_json, still playing query object. instead of to_json, try using to_a array of hashes back.

i'm considering how identify server(s) app on mobile device utilises wcf/web service. (1) anticipate going need migrate server between hosts time time handle load. i'd able without service disruption. (2) anticipate going want improve scalability seperating website hosting , wcf/web service hosting requiring addressing change on client. until app proves traction server deployment shared on same domain. rereleasing client purpose @ glance seems complicated can't force updates on consumers , it's non trivial distinguish between no data connection/server down , server that's moved. i thinking solved problem, thought bounce off community better ideas. what i've come far follows. client needs primary , secondary url reference wcf/web service. caters host provider changes. old host can continue run service during handover period. when succesfully deployed new host, secondary/old host can disabled. wcf/web service stateless, simplifies matters somewhat...
