Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs

Open Conference Expectations

This document lays out some baseline expectations between conference speakers and conference presenters. The general goal is to maximize the value the conference provides to its attendees and community and to let speakers know what they might reasonably expect from a conference.

We believe that all speakers should reasonably expect these things, not just speakers who are known to draw large crowds, because no one is a rockstar but more people should have the chance to be one. We believe that conferences are better -- and, dare we say, more diverse -- when the people speaking are not just the people who can afford to get themselves there, either because their company paid or they foot the bill themselves. Basically, this isn't a rock show rider, it's some ideas that should help get the voices of lesser known folks heard.

These expectations should serve as a starting point for discussion between speaker and organizer. They are not a list of demands; they are a list of rea

Background Info: the last project we worked on needed basic 2D functionality (sprites and animations) and SpriteKit was born to fill this need (http://www.youtube.com/watch?v=cabAr2CdLmc). It has no fancy editors and was really made to fit a specific need and as of yet it has not been extended much further than the video shows. Something a bit more full featured is required for a new prototype and instead of spending a bunch of time extending SpriteKit we went on a search for alternatives. None of the below frameworks are perfect and they all have pluses and minuses. One thing SpriteKit had that none of the others do is automatic texture selection based on screen resolution. That is one thing I would like to see incorporated in every 2D framework and it kind of surprises me that it isn't one of the first features added when making a 2D framework.

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:
