i have tried convert leiningen project boot: https://github.com/borkdude/lein2boot . it uses serve task serve handler. handler offers api , serves files. using reload task, want able reload javascript. i needed place html , javascript @ root of resources directory (in example "assets"), because reload task sends changed javascript browser using full resource path ( /main.js ). means have serve root of classpath: (resources "/" {:root ""}) in compojure. problem can request file entire classpath: no good. when relocate javascript assets/public/main.js , serve public directory: (resources "/" {:root "public"}) , file can requested @ "/main.js", reload task notifies browser reload file "/public/main.js" causes 404. how can solve problem? it looks being worked on in https://github.com/adzerk-oss/boot-reload/issues/18 , allow :asset-path option provide relative roots.

i learning relational model , data modeling. , have confusion in mind regarding sub types. i know data modeling iterative process , there many different ways model things. don't know how choose between different options. example suppose want model particles (molecule, atom, proton, neutron, electron, ...). let's ignore quark , other particles simplicity. since particles of same type behave same, not going model individual particles. put in way, not going store every hydrogen atom. instead, store hydrogen, oxygen , other atom types. going model particle types , relationships between them. i using word " type " carelessly. hydrogen atom instance. hydrogen type. hydrogen type of atom. yes, there hierarchy of types involved. , ignoring lowest level (individual particles). approaches i can think of several approaches model them. 1. 1 table (relation, entity) each type of things (particle types). 1.1 first approach comes mind. proton (proto

for example, dimension d=2 , means generate random angle 0<=a<2*pi , , use (x_1,x_2)=(r*cos(a),r*sin(a)) random vector. however, dimension d>=3 , not generate angle , use represent vector. how generate such vector (x_1,...,x_d) , identically distributed on x_1^2+x_2^2+...+x_d^2=r^2 ? i have come new idea, generate vector (x_1,...,x_d) such -r<=x_i<r i , normalize if x_1^2+x_2^2+...+x_d^2<=r^2 , abondon if x_1^2+x_2^2+...+x_d^2>r^2 . however, there drawback probability x_1^2+x_2^2+...+x_d^2<=r^2 become small if d large. there exist better solutions? generate random variables (x_1, x_2, ... x_d) independent , have standard normal distributions, , normalize dividing sqrt(x_1^2+...+x_d^2)/r. that joint distribution of independent normal distributions rotationally symmetric not true, characterizes normal distributions. you can generate pairs of independent variables standard normal distribution efficiently uniform random variables us

consider (from https://www.owasp.org/index.php/access_control_cheat_sheet ): if (ac.hasaccess(article_edit)) { //execute activity } this correctly implies access control ... policy persisted/centralized in way my question around how best centralise this. one obvious way can think of include activities needing access control in class - hardcoding. can call method hasaccess(article_edit) on class. implies whenever activity added application need add class. another way centralise access control might include controlled activities in database. each time need check access call hasaccess(article_edit) , trigger call database. include method in access control model. firstly, right track please? there other solutions people favour? might benefits/issues of solutions please? you hitting "externalized access control" issue. it's great you've thought of decoupling business logic auhthorization logic. need way express authorization logic.

so referring answer here recommended apple put code in framework can test it. so questions have embedded framework or can create separate project , put extension code in there? my concern because upon creating extension comes info.plist file , entitlements file , unsure should putting in relation framework , such. also once have made separate or embedded framework project, how set host test? mine interested in host app being photos, saying need actual storyboard load derives slcomposeserviceviewcontroller . create app delegate target can set host, , have load maininterface.storyboard of extension start testing? update so have discovered difference between application testing , logic testing. update question slightly, there way application test extension ui? assumption have app host target , load first view extension storyboard view.
