(a^x) % mod == (a^(x % (mod - 1)) % mod. if mod prime. is property true when 'a' matrix? suppose a= 1 0 1 1 0 0 0 1 0 x=1000000007 , mod=1000000007 then ( a^x ) % mod is 097981108 432592815 646971665 646971665 451009450 432592815 432592815 214378850 451009450 but (a^1)%mod [ as, ( x % (mod-1) )=1 ] same matrix. that property ( assuming understood correctly ) false. just consider a = 1 0 // 0 2 x = 3 mod = 2 you a^3 % 2 != a^0 % 2 because left : 1 0 // 0 0 right: 1 0 // 0 1

i've done simple jquery slider $(document).ready(function(){ $('li').hover(function(){ $(this).children('div').slidetoggle(); }); }); like this. works perfectly, div 's hidden , display when hover li item, there's problem. when press "back" button in browser slidetoggle "freezes" in "opened" position (meaning div displayed) , start working backwards. ideas fix? try sliding them document ready, so: $(document).ready(function(){ $('li > div').slideup(); $('li').hover(function(){ $(this).children('div').slidetoggle(); }); }); this assure divs slide upwards , prevent working 'backwards'.

many lisps had fexprs not included in cl. read because fexrps don't work static analysis. can explain this? from wikipedia article on fexprs : at 1980 conference on lisp , functional programming, kent pitman presented paper "special forms in lisp" in discussed advantages , disadvantages of macros , fexprs, , condemned fexprs. central objection that, in lisp dialect allows fexprs, static analysis cannot determine whether operator represents ordinary function or fexpr — therefore, static analysis cannot determine whether or not operands evaluated. in particular, compiler cannot tell whether subexpression can safely optimized, since subexpression might treated unevaluated data @ run-time.

i'm making 2d, top-down zelda-style web single player rpg... i'd store dialog in json format... currently i'm getting json external javascript file. json stored such in js/json.js: function getjson() { var json = { "people" : [ {//npc 1 - rescue dog etc... then use in main game javascript file such <script src="js/json.js"></script> ..` var json = getjson(); then use such: labels[index].text = json.people[index].dialogs.start.texts[0]; does matter if keep json js file in javascript function? or should stored .txt file parsed? thanks! it not matter json data javascript store .js , later on can add more data related functions if needed, btw data file has getjson function doesn't make sense store .txt on other hand if api serving data need not have extension @ all.

i have save different profiles of user various social media.for example user may have 1 facebook , 2 twitter profile. if save each profile inserted new document in different collections facebook , twitter collections , how relate document another. used dot notation in mongodb. if relate facebook , twitter profile of same user means easy fetch record.how design schema ? , how avoid duplication ? possible use facebook id twitter id unique? new mongodb . how join documents different collections this ruby implementation, hoping able translate schema logic java code. class user has_one :facebook_profile has_one :twitter_profile end class twitterprofile belongs_to :user end class facebookprofile belongs_to :user end you can enforce unique indexes on collections so: db.twitter_profiles.ensureindex({user_id: 1 }, {unique: true}) db.facebook_profiles.ensureindex({user_id: 1}, {unique: true}) you can use whatever field want enforce uniqueness @ us...
