i have div holds number of smaller divs. these smaller divs used displaying pictures... not sure best way of explaining is, i'll add couple of images anyways, in design view, have divs looking perfectly, or @ least near example above. lined looks whatever element. however... when go print view, pictures divs shrink in size. lot of time isn't much, barely noticable, enough throw layout off. have tried on both chrome , firefox, , have downloaded opened in adobe; every time comes out same way. i've thrown can think of @ haven't been able figure out why happening. here's css in regards larger div: .image-grid{width:274mm;height:99.5mm;padding:3mm 0 0 7mm;} .image{width:34.5mm;height:20mm;background-repeat:no-repeat;background-position:center center;background-size:cover;margin-right:2.99mm;margin-bottom:3mm;float:left;padding:0;} .image-end{width:34.5mm;height:20mm;float:left;background-repeat:no-repeat;background-position:center center;backgroun

i have simple code: var express = require('express'); var router = express.router(); router.get('/', function (req, res, next) { req.lectalapidata = { model: email, conditions: req.query }; router.use(function(req,res,next){ //this not executing console.log('do that') res.json({ok:'ok'}); }); }); i doing wrong, according docs, says can use syntax: http://expressjs.com/guide/routing.html what doing wrong? perhaps it's because router.use nested inside router.get - so question becomes - how create more middleware same route inside router.get middleware? just keep adding functions router.get('/', , executed in order. don't forget call next . router.get('/', function (req, res, next) { req.lectalapidata = { model: email, conditions: req.query }; next(); // pass off next middleware }, function(req,res,next){ console.log(&

i trying create simple particle simulation. there 2 types of particles static , moving. static particles attract moving particles towards centre. static particles have strength attribute dictates how hard pulling moving particles var angle:number = math.atan2(moving.y - static.y , moving.x - static.x); var dist = point.distance(new point(moving.x,moving.y) , new point(static.x,static.y)); moving.velx += math.cos(angle + math.pi) * static.strength / dist; moving.vely += math.sin(angle + math.pi) * static.strength / dist; the problem when particle passing through centre distance small results in large velocity values. i added check distance before calculating velocity. if (dist < 1) dist = 1; but problem still persists. cant figure out problem. here snapshot of overshoot happening. normal force fields use square of distance modifier, here use single power of distance, of course force field performs differently. should change var dist line following:
