javascript - Disable Firefox's silly right click context menu -

-

i making html 5 game requires use of right click control player.

i have been able disable right click context menu doing:

<body oncontextmenu="return(false);">

then came attention if hold shift , right click, context menu still opens in firefox!

so disabled adding js well:

document.onclick = function(e) { if(e.button == 2 || e.button == 3) { e.preventdefault(); e.stoppropagation(); return(false); } };

however, if hold shift, , double right click in firefox still opens!

please tell me how disable bloody thing once , (i'm willing revert obscure, hacky, , unpractical solution, long works).

you never able entirely disable context menu in cases, firefox has setting allows user tell browser ignore such hijinx trying pull. note: i'm on mac, setting in pretty uch same place on platforms.

that being said, try event.preventdefault() (see vikash madhow's comment on other question: how disable right-click context-menu in javascript)

c++ - Function signature as a function template parameter -

-
i'd use function signature template argument. works great classes, when try same trick function templates, msvc throws error: error c2768: 'func' : illegal use of explicit template arguments here's code: template <typename signature> void func(); template <typename r, typename a1> void func<r(a1)>(); what should make work? you cannot partially specialize function template, not supported language. can create partially specialized class template static member function, , possibly trampoline function instantiate class template , invoke static function. something this: namespace detail { template<typename signature> struct helper; template<typename r, typename a1> struct helper<r(a1)> { static void call() { // stuff r , a1... } }; } template<typename signature> void func() { detail::helper<signature>::call(); }

algorithm - What are some ways to combine a number of (potentially incompatible) sorted sub-sets of a total set into a (partial) ordering of the total set? -

-
i have sorting problem i'm pretty sure doesn't have canonical "answer" - has number of different approaches, each pros/cons. i'm interested in hearing different approaches. suppose bunch of people {p_i | i=1,...,m} ranking favorite ice cream flavors. in total there n different flavors, single person p_i ranks n_i << n flavors or familiar with. i'm interested in combining these sub-rankings plausible overall ranking of n flavors. for concrete situation: m , n both 1000 (by coincidence), , each n_i 20 . can assume there's enough overlap in flavors people rank such no flavor "isolated". again, i'm interested in hearing different ways approach this, if there isn't single clear answer. thanks! one way approach problem construct directed cyclic graph representing of constraints on ordering of elements. nodes in graph represent different elements compared , have edge first node second node if had ranked first e
