i'm trying understand few things deal pixels. the first of changes between developing html email , website in terms of appearing on mobile screen. more specific, when developing website, can have media queries run below 375px (i.e. @medie screen , (max-width 375px)) , changes occurring in code not reflected on desktop (since browsers without going inspect restrict width @ 400px); however, on phone has smaller screen iphone se, changes occur under media query hit. so on own makes sense me, because phone screen smaller min browser width, of course changes apply in block hit when website executed on phone. confusion gets introduced. when developing html email, have table set 600px wide. there no media query affecting html. table 600px wide under circumstances, when displaying on less 600px wide phone, assume of page clipped, not so. when viewing email in gmail, entire composition visible. made me scratch head bit, researched , found sources claiming phone greater 600px wide. t

what ast in graphql ? using graphql-js. how anything? nothing in documentation seems explain ast is graphql 2 things: a query language a type system when graphql server receives query process comes in string. string must tokenized , parsed representation machine understands. representation called abstract syntax tree. when graphql processes query, walks tree executing each part against schema. converting raw strings ast first step of every compiler c++ chrome's javascript's vm babel. as graphql , how helps, here video may explain in bit more detail. https://www.youtube.com/watch?v=pmwho45wmqy

so asked asked write o(n) function, insertranked(int[] list, int item) , insert element array sorted frequency (i have written boolean function check if int[] list sorted frequency). after inserting element array, array sorted again frequency. for example, insertranked([65, 65, 65, 65, 1, 1, 1, 8, 8, 987, 987, 2, 2, 40], 2) should produce [65, 65, 65, 65, 1, 1, 1, 2, 2, 2, 8, 8, 987, 987, 40] . is possible in o(n)? have thought of storing elements , counts linkedhashmap , using collections.sort() time complexity of collections.sort() o(n*log(n)). here's 1 approach start off based on count. import java.util.arraylist; import java.util.hashmap; import java.util.treemap; public class sortcount { public static void main(string[] args) { int nums[] = {([65, 65, 65, 65, 1, 1, 1, 8, 8, 987, 987, 2, 2, 40}; hashmap<integer,integer> counts = new hashmap<integer,integer>(); for(int = 0; < nums.length; i+

i have .net c# website in iis. if assigned app pool doesn't have memory limit, app memory usage seems grow until there maybe 1gb of ram left, there seemingly garbage collection event , memory usage goes down dramatically. rinse , repeat. however, if set private memory limit (kb) in app pool specific (pretty low, double of app uses initially) value, app grow in memory usage , app pool recycle. is garbage collector aware of iis app pool limit? if not, there way notify garbage collector there one?

i have variable, gamemode, switch between vertical , horizontal whenever screen tapped. issue having takes lower variable , gamemode displays horizontal. how fix switches whenever touchesbegan method called? appreciated! here code issue having: override func touchesbegan(_ touches: set<uitouch>, event: uievent?) { if gamemode == "horizontal" { gamemode = "vertical" } if gamemode == "vertical" { gamemode = "horizontal" } print(gamemode) } it happens because if gamemode "horizontal" , set gamemode "vertical" , after gamemode == "vertical" returns true , set gamemode "horizontal" . try code: override func touchesbegan(_ touches: set<uitouch>, event: uievent?) { if gamemode == "horizontal" { gamemode = "vertical" } else { gamemode = "horizontal" } print(gamemode) }

i using webpack angular 2/4 , using modules lazy loaded. therefore modules , components not included in main .js file, code resides in 1 of files webpack generates counts up: 0.js , 1.js , on. my problem neither chrome nor vs code can debug code within files reason. when include code main .js file, debugging works fine. there can it? example : i have small directive displays local time in html element. use directive in component lazy loaded. when try debug directive (or else lazy loaded) vs code says following: debugging not possible in chrome either. if use directive in root component (or else not lazy loaded) breakpoint working in vs code in chrome. i tracked down files webpack generating main client , parts lazy loaded. each chunk of lazy loaded components located in files named 0.js , 1.js , on - , think here may cause of problem. map files the map files debugging generated accordingly, output: look *.js.map file not created. if using angular c

my current project using fips resources of bouncycastle encrypten/decryption signing , on.. keys still generated usual c# bouncy castle. now, because waste want change code, can't find documentation on how this. what have far: ecdomainparameters s = new ecdomainparameters(...?) fipsec.keypairgenerator ecgen = cryptoservicesregistrar.creategenerator(new fipsec.keygenerationparameters(s)); but how specify type of curve, g , n? thanks in advance if can somehow. i found examples in bouncycastle unit tests. try downloading code tests: https://www.bouncycastle.org/csharp/download/bccrypto-csharp-1.8.1-src.zip or find appropriate source on web page: https://www.bouncycastle.org/csharp/index.html then class unit test: ectest for example have code this: /** * key generation test */ [test] public void testecdsakeygentest() { securerandom random = new securerandom(); biginteger n = new biginteger("88342353238919216479164875036030888480755034

there method creating data. method needs called once. structure: var datacreated : bool? = false override func viewdidload() { super.viewdidload() if datacreated! == false { createdata() self.datacreated = true } } is right way ensure createdata() method called once? thank you. since want createdata called once per instance of view controller, using viewdidload place call it. further, since viewdidload called once per instance of view controller, there no need datacreated property. can remove that. override func viewdidload() { super.viewdidload() createdata() } another option call createdata init method of view controller. depends on createdata needs access. if createdata method needs access views , outlets, must use viewdidload .

my grammar must ignore whitespaces part, except in contexts. answers this question advises define specific lexer rules handle exceptions want. the problem (i think) cannot handle such cases @ lexer level, since seem triggered high @ parser level. to more specific: want recognize like myrule: myparsetree1 operator myparsetree2 // ws skipped | myparsetree1 ws sensitiveoperator ws myparse // ws carries meaning keeping in mind have ws -> skip rule because in of grammar whitespaces should skipped. in xtext , rules can specify on rule-scoped basis hidden tokens apply within rule's scope: myrule (hidden comments): ... // ws reaches parser, comments don't myrule2 (hidden ws, comments): ... // ws skipped, comments but clueless antlr4. if want skip tokens depending on grammar context should have @ question here given procedure described skipping whitespace (as want it).

i attempt test service fabric node balancing mechanism on own private cluster , can’t figure out why doesn’t work. below steps took: configure cluster resource manager timer periodically check balancing state 5s, set balancing threshold metric “memoryusage” defined 2 , define node capacity metric 1200. clustermanifest looks like: clustermanifest create 2 stateless application: 1 called “nodebalancingtestappwith500” defaultload 200, weight high , instance count 5 , other 1 called “nodebalanceteststatelessservice” static load 400, weight high , instance count 1 publish both cluster. applicationmanifest looks like: applicationmanifest after publish 2 apps cluster, load in 5 nodes 200,200, 600, 200 , 200. expect see app “nodebalancingtestappwith500” defaultload 200 in node 3 should moved node after resource manager kicks in. after balancing , should 200,400,400,200,200 this? could tell why node balancing doesn’t work? seems there no capacity violation

recently implemented qnx neutrino rtos on zynq-7000 platform (arm a9) , measured scheduling jitter different task frequencies no cpu load. in test wait in msgreceive function pulse generated timer. read high frequency clock fpga (100mhz). measured scheduling jitter 10hz, 100hz, 1khz, 10khz , 100khz tasks , got strange results. short period task got (-300,+300) nanoseconds jitter, longer periods got following: 1khz task had (+600, +1300) nanoseconds jitter 100hz task had (+8, +12) microseconds(!) jitter 10hz task had (+69,+71) microseconds jitter jitter not grow bigger longer period tasks, greater zero. didnt expect such differencies. provide explanation of such behaviour? might explained posix standard, allows timers expire not prematurely overhead? why did become more visible long period tasks?

i working on project have automapper profile class has mappings. however, reason, need call service , in order call service, need call inject service in profile class. so class looks following: public class myclass : profile { public myclass { //somemapping here } } now, want inject service, needs take service in constructor , constructor following: public myclass(iservice service) { //somemapping here } now, services.addautomapper(); calls classes inherit profile class auto magically , , not call parameter constructor. now question best way call service in automapper profile class? addautomapper() extension method synthatic sugar. needs can initialize automapper manually: mapper.initialize(cfg => { cfg.addprofile(new myclass()); }); https://github.com/automapper/automapper/wiki/configuration#assembly-scanning-for-auto-configuration maybe solve issues.
