i have situation, dictionary created, key-value pairs added, , after point dictionary used reading values. i'm trying implement quickest way of adding dictionary in initialization phase. concurrentdictionary has slow tryadd method (and getoradd) - on 6 core cpu (12 threads), cpu usage stays @ 25%, indicating 3 threads used. it faster add keys (around 25 million) dictionary sequentially, using concurrentdictionary , parallel.for. how can improve speed here? easy separate key-value pairs, keys never collide when added dictionary, using code below creates problems: dictionary<long,string> d = new dictionary<long,string>(); d[key] = value; it seems this, when used in multi-threaded environment, fails because dictionary internal changes (resizing?). would work instead? capacity = 250000000 //basically big enough store data dictionary<long,string> d = new dictionary<long,string>(capacity); d[key] = value; i prefer using dictionary on concurre

if have set activity in android fire onnewintent() when receives intents when in stopped or paused state. goes through following sequence if receives intent while running: onpause() -> onnewintent() -> onresume() but if paused due user action onpause(). now if want in case user hid app not in case getting new background intent. doing example cancelling recording when app gets hidden, seems screwed. you wont know until sometime in future whether got onpause because user hid app or because of incoming background intent. am missing or broken? why don't send onnewintent callback if intent while running. rather pause, onnewintent, resume sequence? if stumbles upon again - not possible detect if onpause() called due new intent onresume() can detected. add bundle_key_new_intent_called when onnewintent() called , check flag in onresume() , take required action. @override protected void onnewintent(intent intent) { super.onnewintent(intent);

very often, case there compilation error in project, yet can't find source of error. for instance: this web project has error, yet it's guess error is. why isn't there way right-click option called "find source of compilation error"? there's no quick fix option available. this simple question. don't understand why issue, because eclipse knows problem is, why won't eclipse tell me? press ctrl + 3 type problems , hit enter . should show list of issues in project.

i've been playing around nsvisualeffectviews in yosemite , transparent titlebars wondering if it's possible have custom title bar, own base color (not gray), act apple's. here's current nswindow : achieved setting following code on custom nswindowcontroller : self.window.stylemask = self.window.stylemask | nsfullsizecontentviewwindowmask; self.window.titlevisibility = nswindowtitlehidden; self.window.titlebarappearstransparent = yes; that blue color custom nsview that's painting rect particular color. content below nstableview . so, goal have titlebar work like, let's say, maps instead of having "base" color gray color, "base" color blue 1 , when nstableview scrolls, content appears below title bar. any ideas on how achieve this? thanks have tried setting blue color transparency of, e.g., 0.75 in blue view, , nsvisualeffectview underneath it?

is there way convert html5 date input 1 format another? for example: 2014-06-18 11:17:17 18-06-2014 11:17:17 ? <input type="time" name="time" /> each browser shows differently. opera (presto engine) shows right way. chrome (webkit engine) shows in am/pm. firefox (gecko engine) doesn't show anything, validates. input type=time based on idea of localization takes out of hands of page author. intentional; problem has been raised in html5 discussions several times, same outcome: no change. (except possibly added clarifications text, making behavior described intended.) that should use input type=text, pattern attribute , javascript checks input correctness on browsers not support pattern attribute natively.

i developing system log app users check device's log. know using logcat app can read system log in real-time, there way read "history" system log, 1 week? (our app may down during week) updated: i builder of custom android os, based on aosp. system log app running in os only. have ability develop drivers, framework layer , system apps besides normal apps. if normal app cannot accomplish task, how developing driver additionally? know there driver module named "logger" in kernel, in charge of logging. maybe can add code "logger" , let dump logs files: log_20140629.txt, log_20140630.txt , on. every file contains log in whole day. app read these files. idea possible? we know using logcat app can read system log in real-time only on devices running android 4.1 , lower, or possibly on rooted devices. android apps on android 4.2+ cannot hold read_logs permission. but there way read "history" system log, 1 week? i ha
