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

Some random notes on the pangs of ember. Will be expanding as they are uncovered.

Building a form

Say you have a form that maps to a model, something like:

<form>
  <fieldset>
    <legend>Who are you?</legend>

{
    // --------------------------------------------------------------------
    // JSHint Configuration, Strict Edition
    // --------------------------------------------------------------------
    //
    // This is a options template for [JSHint][1], using [JSHint example][2]
    // and [Ory Band's example][3] as basis and setting config values to
    // be most strict:
    //
    // * set all enforcing options to true

View Context Changes

The rules for how Ember.js evaluates Handlebars templates have recently changed, and you may need to update your application's templates to ensure they continue working..

Template Contexts

Remember that a template is always evaluated against a context object. When you render a template, values are looked up from that object. For example:

Hello, {{firstName}} {{lastName}}!

- Trailing commas are ok
- No reserved words for property names
- NaN, Infinity, undefined : are all constants
- parseInt() defaults to radix 10
- /regexp/ produces new reg ex object every time
- JSON.parse(), JSON.stringify()
- Function.prototype.bind
- String.prototype.trim
- Array.prototype.every, filter, forEach, indexOf, lastIndexOf, map, reduce, reduceRight, some, 
- Date.now()

Backstory: I decided to crowdsource static site generator recommendations, so the following are actual real world suggested-to-me results. I then took those and sorted them by language/server and, just for a decent relative metric, their Github Watcher count. If you want a heap of other projects (including other languages like Haskell and Python) Nanoc has the mother of all site generator lists. If you recommend another one, by all means add a comment.

#Rendering

#Redirecting
