i'm trying implement kind of interrupt routine. it's related virtualization gic v2 h/w support. my question : when catch interrupt number, hypervisor should distingush if it's own or guests ran on hypervisor. how check it? if it's hyp or guest? it's question. please let me know if correct or not. need more backgrounds. thank replay before. the simplest way fiq interrupt assigned secure world , irq normal world. there trustzone register ( scr or secure configuration registers) route irq/fiq monitor or straight os in current world . gic allows interrupt either fiq or irq (i think documentation calls type 0 , type 1 ). can route monitor or can dynamically switch (on world switch) interrupt routed. world | normal | secure ------+--------+-------- fiq | monitor| through irq | through| monitor the monitor trap require saving lot of registers (a world switch save registers). can trust secure interrupt handler somewhat, bets shou...

i have been refactoring old code uses iife fetch , initiate set of values. var exampleinitiate = (function exampleinitiate(){ ..call backend service })(); now, per new requirement, have call same iife argument, , argument result of promise invoked later. understand iife invoked, , if result of promise, able call iife again? understands iifes run once only. i thinking best not use iife here not fit here in case. correct, or there indeed way call iife passing argument value promise? you can have couple of options if understand correct. first can pass argument iife this: var mypromise = getpromise(); var exampleinitiate = (function exampleinitiate(promise){ promise.then(function() { ... }); ..call backend service })(mypromise); but wouldn't call way clear. suggest erase iife , use promises do: getsomebackendresponse().then(function (data) { ... }) edit: if iife returns promise yes, think can't pass in result of function again, since iife invoked o...

i have method takes upper limit, , returns list of primes numbers limit. public static list<int> allprimesunder(int upperlimit) i later decided needed lookups on list, asking question "is prime". since dealing primes under values million, realized hashset structure should using. lookup using result of method faster, method self slower . i believe reason it's slower because hashset checks duplicates before adding, while list shoves on end. surprised me, , spawned question , title, why starting list , using create hashset, so: hashset = new hashset<int>(prime.allprimesunder(1000000)); is faster using hashset internal method, enabling call this: hashset = prime.allprimesunder_hash(1000000); if slowdown in duplicate checking, should have same amount of checking no matter what, right? understanding failing me. here times i'm getting primes under 1 million. 0.1136s pure hash 0.0975s pure list ( expected faster ) 0.0998s pure ...

i'm working on code includes database access. test-driven development include integration tests usual unit tests? thanks! golden rule of tdd says: never write new functionality without failing test. if not following rule, doing tdd partially (like writing unit tests several classes in application). that's better nothing (at least know these classes required, cannot sure other parts of application working , these classes can integrated them), not guarantees application works expected. so, need start each feature writing failing acceptance test, guides application design , defines application behavior (outer loop). while test failing, feature not implemented application. should write unit tests separate units involved feature (inner loop). outer loop verifies classes involved feature working expected. inner loop verifies each class works expected on own. following picture great book growing object-oriented software, guided tests demonstrates these 2 feedback ...
