Meteor Alternatives Per Feature

This table was created in 2015 so may be quite outdated today.

Feature	Meteor Solution	Alternative Solutions	Description
Live DB Sync	[livequery][lq] ([mongo-oplog]), [ddp]	RethinkDB, Redis, ShareDB, [npm:mongo-oplog], [firebase], etc.	Push DB updates to client/server.
Latency Compensation, Optimistic UI	[minimongo][mm]	[RethinkDB][lcr], [mWater/minimongo] (fork, not ws but http, browserify)	Imitate successful db query on client before it is done.
Isomorphic Code	[isobuild] & isopacks	browserify	Write one code for server/client/mobile.
Isomorphic Packaging	[isobuild], atmosphere		No more separate packages for server & client. Get bower + npm + mobile.

Persistent data storage on CoreOS-cluster

Storing the data on the host machine

Data directories are created in /home/coreos and mounted into the container using volume cli options of docker run. All data the container writes is stored on the host and as long as the host persists safe against container restarts / recreates.

Pro
- No effort, just create the directories and mount them into the container
Contra
Container is bound to host (unable to failover)

How to make faster scroll effects?

Avoid too many reflows (the browser to recalculate everything)
Use advanced CSS3 for graphic card rendering
Precalculate sizes and positions

Beware of reflows

The reflow appens as many times as there are frames per seconds. It recalculate all positions that change in order to diplay them. Basically, when you scroll you execute a function where you move things between two reflows. But there are functions that triggers reflows such as jQuery offset, scroll... So there are two things to take care about when you dynamically change objects in javascript to avoid too many reflows:

	/* Random utilities */
	export class Random {
	static getRandom() {
	return Math.random();
	}

	static getRandomInt(min: number, max: number) {
	min = Math.ceil(min);
	max = Math.floor(max);
	return Math.floor(Math.random() * (max - min) + min);
