i have extremely edge case scenario have callback method have define during config. means no scope, no factories, etc... work around use root injector ($injector) , other modules @ runtime. however, when call $injector.get('myservicename') in call (after application running) "unknown provider". same service has no problem (and is) being injected before line of code running. if call $injector.get("myservicenameprovider") can provider in callback.. service has factory can't @ all. so in extremely bad practice, how can snag service configured. heck can't seem $rootscope.. angular inits providers first, factories/services - services not available in app.config . you can deo this: app.config(... window.on('scroll', function() { // executed later $injector.get()... }) or use app.run services available.

an external partner wants authenticate on our systems, using active directory. want use active directory external provider in identityserver4. unfortunately ad @ location runs on windows server 2008r2 (functional level 2003) our best options here integrate identityserver4? simply "turn on" windows authentication in identityserver. see docs: https://identityserver4.readthedocs.io/en/release/topics/windows.html if windows authentication should happen on different machine 1 (main) identityserver installed, create "mini identityserver" runs on machine joined right domain , federate using openid connect. the whole purpose of "mini is" turn windows token jwt (very similar adfs in nutshell).

during code optimisation of project, replacing instances of var keyword let because think there no particular use left var . did 'find & replace' in files this. in custom modules had used statements like: var exports = module.exports = {}; which worked fine. now, after replacing let , became: let exports = module.exports = {}; it not work , gives error syntaxerror: identifier 'exports' has been declared though can use var , avoid problem, still want know reason behind this. edit: have not used let exports = <something>; anywhere in same module file. statement have declared exports variable. the reason because exports initialized in nodejs module system. https://nodejs.org/api/modules.html#modules_module_exports the object exists, module.exports when module loads. since let scope specific preventing limiting scope. const fail.

i'm using line: $(this).css("z-index", z + 10); the set z-index value 1200. edit: variable z = $(this).css("z-index"); when debugging in developer console noticed z-index value '120010' rather expected '1210'. how can change above line increase value 10, rather concatenating value end. (also using word right? i'm not 100% sure) you need use parseint() function on z variable. should work: z = parseint($(this).css("z-index")); $(this).css("z-index", z + 10); one thing careful though, z-index can have value not number, example auto if run parseint() on element that's z-index auto, break. in order combat this, recommend using zindex() (part of jquery ui) instead of css() so: z = $(this).zindex(); $(this).css("z-index", z + 10); this of course means have use jqueryui, if using it, i'd recommend approach. edit: looks zindex() has been removed jquery ui, stick first s...

recently, wanted write type holding parameters 3d projection: use std::ops::range; #[derive(clone, copy)] struct camproj { /// near , far plane proj_range: range<f32>, /// field of view fov: cgmath::rad<f32>, // `rad` derives `copy` /// width divided height aspect_ratio: f32, } however, got error: error[e0204]: trait `copy` may not implemented type --> <anon>:3:21 | 3 | #[derive(clone, copy)] | ^^^^ ... 6 | proj_range: range<f32>, | ---------------------- field not implement `copy` so apparently, range<t> never implements copy , if t copy , f32 is. why that? thought range<t> pair of t s? surely implement copy ? because range<t> used iterator, , having iterators copy was discovered footgun . one specific example had thinking iterator advanced, when in reality copy advanced: for x in { // *copy* of iterator used here // .. } ...
