suppose have 2 objects depend on each other or other objects(so use references these objects) , need save/restore "state" from/to disk. since storing pointers disk not produce correct results on restore, how keep dependencies correct on restore? e.g., class { b b; } class b { { a; } (or more complex chains may have n-cycles of dependencies) a = deserialize(adata) b b = deserialize(bdata) (and suppose need a.b = b , b.a = a) i'm thinking having unique hashes objects lazy evaluation solve problem maybe there better ways? (if have unique hash easy find object use , save , restore object(basically hash acts pointer valid(since unique , never changes))

in node js app im using mongo db , , have issue when inserting in database. when add new record collection objects beign reordered . knows why happening ? im doing insert collection.insert(object, {safe:true}, function(err, result) { if (err) { res.send({'error':'an error has occurred'}); } else { // error } }); actually , operation on collection change order of objects , knows why happening ? mongodb documents have padding space used updates. if make small changes document adding/updating small field there chance size of updated document increase still fit allocated space because can use padding. if updated document not fit in space mongo move new place on disk. documents might move lot in beginning until mongo learns how padding need prevent such moves. can set higher padding avoid documents being moved in first place. in either case can't rely on insertion order sorted list of documents. if want guaranteed order nee...

i'm making form on javascript , want save of users entered variables either .txt file or new webpage variables pre entered in inputs. understand javascript cant manipulate users machine can manipulate servers files(create new files) if can how 1 save variables onto new file in way imported website? input appreciated :) aaron~ javascript running in browser can make http requests server (generally using xmlhttprequest object). it can't write arbitrary files (if could, client could, , deface website) you need form of server side process running on server can interpret http request meaning "write file" (although, in cases, write database , generate file on request data there). you write server side process in javascript if have suitable server side environment (such node.js).

i understand that: atan2(vector.y, vector.x) = angle between vector , x axis . but wanted know how angle between two vectors using atan2. came across solution: atan2(vector1.y - vector2.y, vector1.x - vector2.x) my question simple: will 2 following formulas produce same number? atan2(vector1.y - vector2.y, vector1.x - vector2.x) atan2(vector2.y - vector1.y, vector2.x - vector1.x) if not: how know vector comes first in subtractions? thanks atan2(vector1.y - vector2.y, vector1.x - vector2.x) is angle between difference vector (connecting vector2 , vector1) , x-axis, problably not meant. the (directed) angle vector1 vector2 can computed as angle = atan2(vector2.y, vector2.x) - atan2(vector1.y, vector1.x); and may want normalize range 0 .. 2 * pi : if (angle < 0) angle += 2 * m_pi;

i understand scaling ratio xxhdpi? ldpi = 3 mdpi = 4 hdpi = 6 xhdpi = 8 xxhdpi = ? mdpi normal, or default. scale factor 1.0. ldpi = 0.75 mdpi = 1.0 hdpi = 1.5 xhdpi = 2.0 xxhdpi = 3.0 xxxhdpi = 4.0 you can scale factor of current screen programmatically, so: final displaymetrics metrics = resources.getsystem().getdisplaymetrics(); scale = metrics.density;

i have int array[4096] . want know minimum value , offset in array, without having ever search through it. obviously, on setting element new value, can compared minimum , replace if applicable. however, if setting offset that's minimum, , making no longer minimum, gets more difficult. how can done, efficiently possible? you can use priority queue supporting deletion , decrease-key support this. whenever value changes, if value decreased, call decrease-key on decrease value in priority queue. if value increased, delete value , reinsert priority queue. assuming priority queue backed structure efficiently supports these operations (typically, binary heaps appropriate bookkeeping can in o(log n) time each), can support faster doing linear scan on elements each time. if don't have binary heap lying around, can use tree-backed map (keys values, elements positions in array) this. hope helps!
