i'm trying create own polynomial class. want make function can evaluate polynomial x given. so far have this, answers giving me aren't right , cant figure out why? polynomials inputted using list. example [2, 0, 1, -7, 13] 2x^4+x^2-7x+13 class polynomial: def __init__(self, coefficients): self.coeffs=coefficients def evaluate(self, x): sum = 0 in range(len(self.coeffs)-1,0,-1): sum+=self.coeffs[i]*(x**i) return sum the i value you're using isn't right both index , exponent. you're evaluating reversed-coefficeint polynomial, evaluation results polynomial([2,3,4]) right value polynomial([4,3,2]) . here's how i'd define evaluate : def evaluate(self, x): return sum(coef * x**exp exp, coef in enumerate(reversed(self.coeffs))) note if want polynomial objects callable (as in p1(4) in example in comment), should rename evaluate function __call__ .

can akka.net , original akka communicate using remoting? in other words can akka used connect jvm , clr in system? this issue on akka.net github https://github.com/akkadotnet/akka.net/issues/132 describes several reasons why doesn't work: 1) use different serializers user messages, akka uses default java serializer, akka.net uses json.net. solved using e.g. google protobuf, serializers pluggable. 2) helios (akka.net transport) , netty (akka transport) not compatible on binary level, both use 4 byte length prefix frame messages (afaik, @aaronontheweb ?) guess won't play nice together. and perhaps more fundamentally: the big issue here this: java bigendian, .net littleendian - @ least, it's littleendian on windows systems. endianness in .net can vary platform platform, true mono too. it appears there not appetite solving issues: i'm wondering how useful full protocol compatibility is. issues point out aside, imagi

i'm working on api endpoint. upon posting data endpoint /authenticate , use plaidclient.getauthuser function user's account information, , i'm trying use res.json return account data. after running this: accounts = json.stringify(res.accounts); console.log('accounts: ' + accounts); i able see array of dictionaries containing account information. however, when attempt use res.json({accounts: accounts}) , error: res.json({accounts: accounts}); ^ typeerror: undefined not function when try run res.send(accounts) in place of res.json, receive same error: res.send({accounts: accounts}); ^ typeerror: undefined not function here's code: var public_token = ""; var access_token = ""; var accounts = []; app.post('/authenticate', function (req, res) { console.log('post'); public_token = req.body.public_token; console.log(public_token); console.log('plaid: ' + app.client);

i trying current time , store when run os command ( runs once second) can plot graph of time vs output of command. when try store current time in list using: (timelist empty list) timelist.append (datetime.datetime.time(datetime.datetime.now())) i this: [datetime.time(23, 57, 8, 86885), datetime.time(23, 57, 8, 87091), datetime.time(23, 57, 9, 90906), datetime.time(23, 57, 10, 95045), datetime.time(23, 57, 10, 95110), datetime.time(23, 57, 10, 95148), datetime.time(23, 57, 10, 95166), datetime.time(23, 57, 10, 95178)] so in 1 second, instead of 1 list item current time, 2, or 3 items). how capture time @ instant , store in list can use pyplot plot this? i using this, , works fine (python 3.3+): from datetime import datetime time_list = [] time_list.append(datetime.now()) if want save or send other application without converting types can think use timestamp rather: from datetime import datetime time_list = [] time_list.append(datetime.now().timestamp())

is there way execute javascript-event before it's natural behaviour? for example, using code below, if press / key on keyboard, character printed in input field, , after 2 seconds, alert showed. that's obviuos. but there way make alert showed before / printed? <input></input> <script> document.queryselector("input").focus(); addeventlistener("keydown", function (e) { if (e.keycode === 191) { myfunc(e); } }); function myfunc(e) { settimeout(function() { alert("hello!"); }, 2000); } </script> unified solution inputted characters on keypress event: addeventlistener("keypress", function(e) { var val = e.which || e.keycode; e.preventdefault(); myfunc(e.target, val); }); function myfunc(target, val) { settimeout(function() { alert("hello!"); target.value = string.fromcharcode(val); }, 2000); } try it.

globals.h #define id1 1 #define id2 2 factory.h item* makeitem(int id); will including new ids in globals.h require recompile of files use makeitem old ids? also how know changes require recompile or re-linking of dependents? any change globals.h require recompile of files #include globals.h or include header files include globals.h. if list of ids changes often, , lots of files depend on it, , project big, might become nuisance. one way around split globals.h different h-files, each h-file used relatively small part of project. then, change in 1 of them not require recompiling. if this, typically face challenge of keeping of ids unique. if defined in different header files, developer making change in 1 file may not know causing collision id defined in file. 1 solution follow documented convention, in every h-file ids defined has associated range of ids, , ranges not overlapping.

i have entity contains lets 20 different keys / local variable. in case want update doc , can use updateoperations in order perform query , have go filed filed , set new value new object.. if there way update current doc in db new fields lets say: public class item { @id @getter @setter private objectid id; @getter @setter private string itemid; @getter @setter private string itemtitle; .. .. } so lets have item stored, got new dto gui, of fields , rest null. want create generic update operation take non nullable values dto object , update in existing doc in db. is possible? i think so! i see 2 possible ways: alternative 1: can use reflection iterate every field in dto , put value copy of document recovered db. @ end of loop can update document. alternative 2: update desired fields. mongo can update subset of fields in update operation: update data java driver
