i'm having trouble figuring out how render react components, children inside other components on serverside. on client side in index.js file i'd like: react.render( <panel title="full time score"> <graph /> </panel>, document.getelementbyid('column-main') ); but on server side i'm not getting luck, possible this? or kind of anti-pattern , should start off 1 parent component. what i'm trying have reusable panel component (it includes button toggles visibility) can put content/components inside. on server, markup returned react.{rendertostring,rendertostaticmarkup} html output of component on first render. on client, components can re-render after componentdidmount lifecycle method has fired. make sure panel component renders children prop on first render.

i have trouble when running r code. contains few functions, problem happens when following function called: w <- function(p) { if (p == 1) pr <- 1 if (p == 0) pr <- 0 if (p != 0 && p != 1) pr <- exp(-(-log(p))^sigma) return(pr) } the problem occurs when argument of w function becomes 1. checked step step execution. found when have w(c1) in other function , c1 has value of 1, return of w function nan. confused because when write w(1), 1, when have w(c1), c1 computed 1 in other function, w function not work. in step step execution, when c1 becomes 1, first if condition not work, returns false, should opposite, since c1 equal 1. what can solution problem?

i've written small restful php backend using slim framework ( http://www.slimframework.com/ ) interfaces mysql database, , right have 1 class doing db interactions , it's getting kinda big. it's time organize little more cleanly. so based on understand mvc, better way might implement model layer so: each logical entity in system implemented data class. i.e. user accounts: class called "account" getid(), getname(), getemail(), etc etc and corresponding factory objects, i.e. accountfactory owns db connection , creates account class manipulate elsewhere in business logic layer. the business logic layer still pretty simple, maybe class called myapplication instantiates factories , uses them respond restful api calls. business logic might be, example, matching 2 accounts based on geographical location. in case, testing on data in 2 separate account objects instead of raw data loaded database. but seems lot of refactoring time spent same thing. why wouldn

the docs silent on questios. commands registered in order, later apps (in settings.installed_apps order) overriding previous commands (whether custom other apps or built-in django commands)? the answer yes, of current 1.7 release. see this line in django source see logic implemented: in order of apps per settings.installed_apps tuple, each app's management commands added dictionary of commands (which initialized django's built-in commands here ), single slot given command name, last 1 added sticks, overriding previous app's (or django's built-in) command same name; when executing command (code here ), django uses dictionary above decide command logic use. note haven't found documentation of this, should technically considered unofficial behavior.

i’m building android app needs communicate server on tcp sockets. know networking should done off ui thread i’m not sure “threading approach” go with: intentservice or asynctask. read should use services if have run continually in background, , use asynctask one-off tasks find rather vague. application need communicate server on startup , when user clicks button, seem favour asynctask (since seems one-off task). benefit , downside of using asynctask on intentservice? i think shouldn't use async task, because async tasks runs in serial execution. slow down application if user go or press multiple times. can use thread handler or can use event bus library. or network task can use volly.
