using microsoft bot framework, how can proxy api between incoming , outgoing bot messages? i've replaced: server.post('/api/messages', connector.listen()); with own implementation takes req.body.text , sends separate endpoint. how can send endpoints response chat? server.post('/api/messages', (req, res, next) => { request.post('endpoint', { json: {"text": req.body.text}, }, (error, response, body) => { // how send body outgoing chat message? }) }) update: to point out why ezequiel jadib's answer won't work, i've added complete code. req not defined within bot's callback function. const restify = require('restify') const builder = require('botbuilder') const request = require('request') // setup restify server const server = restify.createserver() server.use(restify.plugins.bodyparser()) server.listen(process.env.port || process.env.port || 3978, function () { cons...

how to read function type signatures in Haskell? -

this question has answer here: what => symbol mean in haskell? 4 answers given function adds 1 int, can see type signature: prelude> addone :: int -> int; addone x = x + 1 prelude> :t addone addone :: int -> int the signature means addone takes int , returns int. simple enough. instead if define function without specifying type: prelude> anotheraddone x = x + 1 prelude> :t anotheraddone anotheraddone :: num => -> it makes sense dealing num not int whats way read num => -> a ? , difference between => , -> here? anotheraddone :: num => -> the => here separates class constraint , type. in example, num a class constraint, consists of class num , type variable a . full signature declares type a num , function anotheraddone has type a -> a .

javascript - Set all menu items to be center of Bootstrap Menu Header -

recently have resized bootstrap's menu size. problem text position of menu items shows in top of menu bar. i want show menu items center of menu header. menu items aligned in center position. here code : http://jsfiddle.net/y8v0rd9g css: .navbar .navbar-nav { display: inline-block; float: none; } .navbar .navbar-collapse { text-align: center; } .navbar { position: relative; min-height: 80px; margin-bottom: 20px; border: 1px solid transparent } if use browser's dev tools, you'd see links ( ul.nav ) vertically center-aligned, list ends before nav element does. that's because you're setting min-height: 80px on nav. i'd recommend adding padding well, not way @lkg did it. instead, remove min-height rule , add top , bottom padding .navbar . way items remain center-aligned nicely. updated fiddle , updated code: .navbar { position: relative; margin-bottom: 20px; padding: 12px 0; border: 1px solid transparent }

my app has bug on activities: when restarts (when it's killed , opened again multitasker), crashes. assume has singleton, i'm not sure. i'd pinpoint problem, can't debug since debugger stops when kill application (i'm using adb shell kill <package-name> ). does know how can debug problem? (or give me hint problem might matter) i use ddms (dalvik debug monitor server (ddms) capture stack trace, etc.. after kill , restart our app. (fyi: installed along rest of android toolset) while not going allow debug app via vs/xs, can pin area of app cause. there add logging around trouble area (i.e. old-fashion printf style debugging) http://developer.android.com/tools/debugging/ddms.html to launch visual studio: from xamarin studio:
