i trying develop base container extending ext.container, have default items in it. subclass should add items child component of base class , not directly container instead. how this? may override setitems / applyitems method add items navigationview.add(items); ?? i'm unsure how works. since i'm new extjs, unable identify way generically won't affect subclass add n number of items either using inline or add(item) method. abstractclass ext.define('myapp.container.abstractmaincontainer', { extend: 'ext.container', xtype: 'abstractmaincontainer', requires: [ 'myapp.container.navigationview', 'myapp.control.navigationbar' ], config: { layout: { type: 'vbox', pack: 'start', align: 'stretch' }, flex: 1, height: '100%', width: '100%' }, controller: 'maincontroller'

possible duplicate: difference between activity context , application context i want know actual difference between application context , activity context in android ..? these 2 confusing me time. please find me difference two.?? to have gist on application context , activity context read below: the application context live long application alive , not depend on activities life cycle. if plan on keeping long-lived objects need context, remember application object. can obtain calling context.getapplicationcontext() or activity.getapplication(). in summary, avoid context-related memory leaks, remember following: 1.do not keep long-lived references context-activity (a reference activity should have same life cycle activity itself) 2.try using context-application instead of context-activity reference & more info

what causes results below different? -------------- if value = 1 : -------------- string key1 = "123456"; string key2 = "654321"; string x = aescrypto.encrypt(key1, string.valueof(1)); string y = aescrypto.decrypt(key2, x); result --> y = ���8��vw&�s -------------- if value = 2 : -------------- string key1 = "123456"; string key2 = "654321"; string x = aescrypto.encrypt(key1, string.valueof(2)); string y = aescrypto.decrypt(key2, x); result --> y = null why not produce null value 1, not equal value of 2? although both failed decrypt. i don't know library when encrypting 1 key, , decrypting expect undefined results.

i need collect data lots of data sources (e.g., mobile phones). example, 1,000 phones, each uploading batch of 1mb every 20 minutes. thinking use kinesis stream single shard ingest data (the total throughput 1mb/s). make sense individual phones directly access kinesis api, or should put own frontend (e.g., web server) in front? main limits/considerations keep in mind when making decision? p.s. alternative use aws iot infrastructure considerably more expensive you should have web service receives data clients , send them kinesis. web server can use kinesis producer library (kpl) offer best performance in terms of message rate delivery, timeout, policy retry , scalability. kpl can create many workers , can tuned optimize message rate , not exceed write limit imposed kinesys shards. have every single client sends data kinesis overkill in terms of performance, mainenantce costs , delivery. happen if client start sends data @ high rate traffic? shard has rate limit write o

the ipython %timeit magic command job measuring time required run python code. now, want use analogous in python script. know timeit module, however, has several disadvantages, example, how select number of runs adaptively? i.e., default code import timeit t=timeit.timer("code(f)", "from __main__ import code,f") t.timeit() runs code million times. %timeit ipyhton magic command automatically. suggest use matlab code http://www.mathworks.com/matlabcentral/fileexchange/18798 that job automatically (and tells if overhead of function large). how can call %timeit magic python script (or maybe there better timing solution) ? it depends bit on version of ipython have. if have 1.x: from ipython import get_ipython ipython = get_ipython() if have older version: import ipython.core.ipapi ipython = ipython.core.ipapi.get() or import ipython.ipapi ipython = ipython.ipapi.get() once that's done , run magic command this: ipython.magic(&

i trying interpolate 2 points in julia, using same approach of matlab ( https://uk.mathworks.com/help/matlab/ref/spline.html ). have tried interpolations ( https://github.com/tlycken/interpolations.jl ) library, having several issues in creating working script. i have dataarrays.dataarray{float64,1} 2 points (let's 1.5 , 10.5) , 5 na between them: using dataframes using interpolations = @data([1.5, na, na, na, na, na, 10.5]); in matlab sufficient run spline function. in julia, interpolate function allows cubic interpolations. however, seems not working nas. how can it? also, use same / analogous algorithm interpolate points? if make assumption evenly spaced, assuming linear interpolation can use linspace. need start, end, , number of values inbetween: linspace(a[1],a[end],sum(isna(a))) more generally, interpolation between nas, can find non-na values with idxs = find(~isna(a)) and do for in 1:length(idxs)-1 tmpidxs = idxs[i]:idxs[i+1] a[idxs[i]+1

is there elegant way share common symbol definition between delphi , c++ (visual studio) project? the symbol might defined or not defined depending on circumstances. possible define symbol in both projects, might comment out in 1 project , forget in other (or vice versa). if possible, i'm guessing symbol need put .h or .inc file , included in both projects. // delphi {$define common_symbol} //... some_constant = {$ifdef common_symbol} 80 {$else} 40 {$endif}; // c++ #define common_symbol //... #ifdef common_symbol #define some_constant 80 #else #define some_constant 40 #endif in above code, if common_symbol defined, some_constant 80, otherwise 40. here links may help: if need convert c++ header files delphi may try jedi api library . if need convert delphi sources c++ header files may need create such utility yourself. think delphiast start it.

i need place host small basic static web site made of bunch of file , folders (html, css, images, etc.) non-profit. i've looked @ amazon aws bit , looks done small cost. is possible host web site @ amazon aws under $1.00/month? is there way use free aws , determine cost have been if 1 used paid option? is possible host web site @ amazon aws under $1.00/month? if have static files, can host site on s3 low price. if have dynamic website (php, ruby, python, java, etc.) need actual server run on, , more $5 month minimum. note pay data transfer, if site gets popular price start go up. is there way use free aws , determine cost have been if 1 used paid option? you can enable detailed billing on aws account. punch numbers aws cost calculator see charges have been if not in free tier period.

when upgraded javafx app javafx 2 javafx 8, noticed scrollpanes showed gray rectangles, background color set or background set transparent. i found solution in discussion: https://community.oracle.com/thread/3538169 first needed this: .scroll-pane > .viewport { -fx-background-color: transparent; } then set background color whatever like. in case, i'm making scrollpane backgrounds transparent: .scroll-pane { -fx-background-color: transparent; }
