javascript benchmarking with jsperf

I might be a bit late ~~(yeaikno it exist over a year now and a bunch of blogs had it covered)~~ but nevertheless i would like to point out a very helpful online tool i recently ran into:

jsPerf

Its basically a online benchmark tool for testing different approaches in javascript.
It covers some important aspects of benchmarking, that your homemade bench probably wont have like milliseconds accuracy & statistical analysis.
The tests are run on your browser and the results will feed the “browserscope”. A graph of the “highest known results” for the participating browsers.
So we can see some kind of comparison.

modulo in Twig

Ever wondered how to use the modulo operator in twig, the template engine of symfony?

Actually its like in PHP:

{{ 11 % 7 }}

As described here

But i guess for most use cases modulus is used to check if a number is divisible by another number.
Therefore Twig has the very conveniant divisible by test function.

{% if loop.index is divisible by(3) %}

Silverstripe Setup Script

We thought we had to improve our SilverStripe setup script for our development environment.
So Max and me rewrote it to add submodules and some other improvements.

Just run:

./install_silverstripe.sh mynewproject tags/2.4.7

and you have

silverstripe project folder structure
the tutorial theme
a already filled git repository
sapphire as submodule
cms as submodule
Uploadify as submodule
DataObjectManager as submodule
UserForms as submodule

Silex and MongoDB simply

Using MongoDB in your Silex Project is quite easy.

I will show this with my Superleansilexplate and will integrate it there as an example.
Since i dont want to integrate MongoDB in Superleansilexplate it will just become an additional gist.

Given you have some smaller amount of data like a counter that needs to be stored or other loose coupled datasets, we simply speak to MongoDB “directly” and store the data via Doctrine MongoDB Abstraction Layer.
Since i presume the Data / Document Structure isnt that complex we dont use Doctrine MongoDB ODM (the Object Document Mapper).
If you want to use it instead, try this Silex Extensions.

extend SilverStripe memberprofile module

Alright, SilverStripe again, still our CMS of choice.
Today i’d like to promote a very helpful module that provides Register and Profile Pages for Members for the Frontend.
The memberprofiles module.
It comes with a lot of features and customize options for nearly everthing you might need for Frontend Member Handling.
Further it is fully extendible to customize it even more.

For a starter tutorial i recommend a very good post by deadlytechnology.
I would like to describe how you extend it.

First lets install it (with the orderable module dependency):

Silex and the HTTP_CACHE

The HTTP_CACHE resp. the reverse proxy of Symfony is a pretty cool thing.
And as it is build-in Silex it can speed up the already fast micro framework massivly,
wich is good for me, as i am mainly workin with Silex right now.

To enable it you have to register it first like its shown in the docs:

 $app->register(new Silex\Provider\HttpCacheServiceProvider(), array(
 'http_cache.cache_dir' => __DIR__.'/cache/',
 ));

Also provide the writable cache dir.

Enable Twig-Extensions in Silex

UPDATE
Please have look here for a updated version.

Note: its about Twig-extensions not about the former “Silex Twig Extension”, this now called TwigServiceProvider.

First fetch the Twig-extensions code and put them in your vendor dir:

git submodule add git://github.com/fabpot/Twig-extensions.git vendor/Twig-extensions/fabpot
git submodule init
git submodule update

Then register the autoloader by using registerPrefixes:

$app['autoloader']->registerPrefixes(array(
    'Twig_Extensions_'  => array(__DIR__.'/../vendor/Twig-extensions/fabpot/lib')));

Sending invalid Unicode via socket.io

Well you can try to, but it will end up almost probably in an disconnect which is caused by the browser.
As i have learned here.

Given you have a string which contains invalid unicode like:

This will trouble the browser and the socket connection.

If you prepare your json with PHP and json_encode the Unicode will be escaped to some strings like these:

\ud83d\ude31\ud83d\ude31\ud83d\ude04\ud83d\ude04\ud83d\udc9c\ud83d\udc9c\ud83d\udc4a

But on clientside it will still result in invalid Unicode.
