i want have generic class enforces rules derived class in template method pattern avoid two-phase initialization because don't want objects in partial invalid state if possible. base class requires "thing" generic class of used polymorphically. seperate factory isn't appropriate because don't yet know derived classes be. this came using function pointers derived class passes down during construction base class can have thing , way derived object can never exist without valid thing. wonder if there better way in c++ because seems pretty hackish? edit: corrected bit better syntax without function pointers. think simplest way this. class thing {}; class base { public: base(thing* thing): musthavething(thing) {}; virtual ~base() { delete musthavething; }; private: thing* musthavething; }; class derived: base { public: derived(): base(creatething()) {}; private: static thing* creatething() { return new thing; } };

i have umbraco 7.5.6 site, publish at/unpublish @ work fine on local. however when deployed production, it's if these events aren't fired. i've made sure date formats , timezones same on machine , on server. made sure database date format matches those. any ideas should looking? i've seen on few servers, when website can't resolve itself. task makes call unpublish/publish @ accesses site call controller action. if can't access itself, events never fire. happens in more secure environments. you'll able see looking in log files in "/app_data/logs/" folder. there lot of messages scheduled publishing task failing if problem.

i have javascript project released node module. reasons, have source code using relative paths import other files in project: // <this_module_path>/action/foo.js import execution './execution'; import types '../types'; and using module name root path import other files in project: // <this_module_path>/action/dosomething.js // using module name import // equals import './helpers.js' in case (in same folder) import executionhelpers 'this-module/action/helpers.js'; // equals import '../types/helpers' in case import typehelpers 'this-module/types/helpers.js'; how can have such file import other project files using module name rather relative paths? nodejs uses commonjs import javascript moduels. there no clear timeline adding es6 import / export syntax nodejs. need transpile code using babel commonjs module system before can run on nodejs. how using commonjs create separate package this-module mod

loading data , store them in indexeddb database. periodically have database crashes , lost access it. give me, please, solution how use indexeddb asynchronously! sample code i'm use now: var datatotal = 0; var threads = 6; //openindexeddbconnection(); function start(total){ datatotal = total; (var = 0; < threads; i++) { loaddata(i); } } function loaddata(datanum){ var datanext = datanum + threads; if(datanext > datatotal){ //checkend(); return; } $.ajax({ url: baseurl, data: {offset: datanum}, success: function (data) { successdata(datanext, data); }, type: 'get' }); } function successdata(datanext, data){ var dataarray = data.split(';'); savedata(dataarray); loaddata(datanext); } function savedata(dataarray){ putitem(); function putitem(i) { var count = || 0; if(dataarray.length <= i){ return; } var transaction = indexeddb.transaction([datatablename], &qu

i'm using library requires secret string. i've set node variable so: export jwt_secret=e177920e88165bd0090b1c6b544cf7 however, when try use in app, so: const jwt = require('jsonwebtoken'); function usertoken(user) { return jwt.sign({ user: user.id, }, process.env.jwt_secret); } it hits error says secret must string or buffer. thought node variables strings, not sure issue is. thanks. hmm, works fine me. maybe try adding console.log(process.env.jwt_secret) check env var being loaded correctly. as side note, consider using kind of environment variable management library such dotenv . allows store of environment variables in .env file like: jwt_secret="abc" other_env_var="def" it makes easier keep track of env vars :)

i've been using these read , write functions (provided @alk). problem don't know how correctly send uint16_t data_size; . here actual code send general example buffer: uint16_t data_size; int retry_on_interrupt = 0; char buffer[] = "hello world!"; data_size = (uint16_t) sizeof(buffer); /* sending data_size */ writen(socket, data_size, 2, retry_on_interrupt); /* sending buffer */ writen(socket, buffer, sizeof(buffer); and here actual code receive general example buffer: /* receiving data_size */ readn(socket, &data_size, 2); /* receiving buffer */ readn(socket, buffer, data_size); but not working, think because writen requires const char * , instead i'm using uint16_t ... how should these calls be? thanks. replace writen(socket, data_size, 2, retry_on_interrupt); by if (-1 == writen(socket, &data_size, sizeof data_size, 1)) { perror("writen() failed writing size"); exit(exit_failure); } and repla

we're using gtm load universal analytics , want send custom events js ga. need this: ga('send', { hittype: 'event', eventcategory: 'legitimation', eventaction: 'is returning customer', noninteraction: true }); but don't know when ga has loaded since gtm makes async. how can know when ga() ready? sending ga events not through tag manager if load ga through gtm little bit tricky. can´t use normal events use if have ga hardcoded on page. here thread - answering question: https://productforums.google.com/forum/#!topic/tag-manager/c2j4nt8dbxw i suggest send datalayers instead of events, catch datalayers gtm , send events through gtm. makes lot easier.

i'm debugging lengthy code involves cuda operations. i' getting above mentioned error during call cudamemcpy(...,...,cudamemcpyhosttodevice) i'm not sure speficially related that. here code snippet: int num_elements = 8294400; // --> tried "1" here didn't work either! float *checkarray = new float[num_elements]; float *checkarray_gpu; cuda_check(cudamalloc(&checkarray_gpu, num_elements * sizeof(float))); cuda_check(cudamemcpy(checkarray_gpu, checkarray, num_elements * sizeof(float), cudamemcpyhosttodevice)); cuda_check(cudamemcpy(checkarray, checkarray_gpu, num_elements * sizeof(float), cudamemcpydevicetohost)); where cuda_check macro printing cuda error (this part of existing code , works fine other cudamemcpy oder cudamalloc calls not part of problem). strangely code snippet executed separately in toy *.cu example works fine. so assumption due previous cuda operations in program, there have been errors have no

i have conceptual question , wanted know if kind enough help. i use simple example explain point of view. i have developed simple restful api node.js + express + mongodb backend. api saves hightscores android game app. use token-based authentication, tokens generated secret , trusted username/password (hardcoded or not). but still have doubt thinking safety... reverse engineering piece of cake since developer can find backend endpoint of api , use username , password (or hardcoded one) obtain token. then token ca used insert fake highscores via api. my questions are: is there way avoid security hole? is using restfull api correct way connect mobile app backend in server? if not, correct way develop app-server comunication save data in backend db?. i think can ofuscate code includes hardcoded username , password dont solve situation. pd: users question broad. made 3 concrete questions , topic avoid visibility of app information connect api. know there answers,

i've replaced s in following lambda expression _ : s -> integer.parseint(s) eclipse compiler says: '_' should not used identifier, since reserved keyword source level 1.8 on. i haven't found explanation in jls §3.9 lexical structure / keywords. the place jls §15.27.1. lambda parameters it compile-time error if lambda parameter has name _ (that is, single underscore character). the use of variable name _ in context discouraged. future versions of java programming language may reserve name keyword and/or give special semantics. so eclipse message misleading, same message used both cases, when error generated lambda parameter or when warning generated other _ identifier.

i have data frame cols "x", "y" , ordinary rows ("x" , "y" can treated collections of numbers) . want plot bar-chart x tied "x" , y tied "y". tried use geom_bar(stat='identity') produce unexpected me result - figured out sums y-values of corresponding bar x-value. when tried stat_identity(geom='bar') result nice, 1 problem occured: can't figure out how set fixed alpha stat_identity (seems automatically binds number of samples corresponding bar x-value). here examples: ggplot() + geom_bar(data = xs, aes(x, y), stat = "identity", alpha = 0.5) ggplot() + stat_identity(data = xs, aes(x, y), geom = "bar", alpha = 0.5) so, once again, goal : to plot bar-chart x tied "x" , y tied "y" . hence second example solves it, there issue alpha parameter. update: file test data can found here . or github gist there . the problem want bar_plot dat
