i have numbers list go through it, , doing simple calculation 2 numbers: i have numbera , numberb, , calculation im doing is: val res = (numbera/numberb) * 100 now, dont know type number, know float (with 2 nums after dot) or integer... so want know syntax in scala calculate it? currently have: val num1 = (vatreclaimed.toint/vatpaid.toint) * 100 but dont work, , cannot use toint guess since dont know type... whats important me res hold right answer, if 2.3 * 4 res hold 9.2 thanksss! when not know type only, number, have work numeric . numeric can convert numeric value double, float, int or long . precision recommend double : def calc[a : numeric, b : numeric](a: a, b: b): double = (a.todouble / b.todouble) * 100

i have datatables table set call json server. able format rows based on data in each row this: https://datatables.net/examples/advanced_init/row_callback.html so using code in link code so: <script> $(document).ready(function() { testtable = $('#mylist').datatable({ // current proprerties , ajax stuff "createdrow": function ( row, data, index ) { if (my own conditional) { $('td', row).eq(5).addclass('highlight'); } } }) however when run error: uncaught typeerror: cannot read property 'replace' of undefined i new jquery , datatables i'm not of start this. has come across before?

i trying understand bit more flux architecture , designing simple login component. suppose when login (post ajax) , error comes back. how information flow in flux? i think logincomponent should work on handlesubmit function. after ajax call comes error , message should component create action such "updateloginstatus payload {message: "no e-mail found"}. trigger loginstore or save status message , emit event such "loginstatusmessagechanged". another totally different component called loginstatusmessage register listen events on loginstore. notified of event , proceede update it's own state message. go out loginstore , fetch message , display user via render. i believe example covere question quite well: https://github.com/przeor/react-router-flux-starter-kit/

heroku says (free) must sleep 6 hours in 24 hour period ok, that´s fine. but can influence message or text shown user like: "hello user, unfurtunately the website needs rest, please try again 6 a.m 2 a.m ". i can influence uptime, because of sending ping every 20 min. i found this : ... free dynos allowed 18 hours awake per 24 hour period, , on next few weeks begin notify users of apps exceed limit ... if you're using cdn create scheduled task replaces root page static page @ time of day, make sure cdn updates page, , spin down app 6 hours. the docs cloudflare might place start learning how cdn works , how set (see: cloudflare support > getting started ). of course use different content delivery network (cdn) service.

suppose, have 2 configurations. first one: interface { ... } class implements { ... } class b implements { ... } class component { i; component (i i) { this.i = i; } } second one: class c { ... } class extends c { ... } class b extends c { ... } class component { c c; component (c c) { this.c = c; } } what in difference between 2 configurations using 2 different loose coupling mechanisms (based on interface , based on class)? why should need use interface on class? an object can implements multiple interfaces can extends 1 class, user of loose coupled library may not able extends class. when extends, incorporate code of superclass yours, there no code incorporate implements better suited. finally not same paradigm, when write "b extends a" "i a, same things, can make other things". when write "b implements a" "i b, can treat me a". long st...
