Silex, Twig und HTML5 BoilerPlate

Alright, there is a bundle for H5BP for symfony2 and there is Assetic, you can probably use both with Silex and thats just fine.
But in case you want to keep your Silex project lean (since its micro) you can use Twig and H5BP only and build / deploy your app from the outside.

With a little tuning of the H5BP build, of course / unfortunatly. (Ok thats the caveat)

So i have a structure like so:
web/
(this is the webroot, here is js/css/images, all that asset stuff and the index, here we use the recommended H5BP stuff’n’structure)
views/
(this is outside of webroot and here are all of the *.twig)

2 ways to your offline wikipedia

… for whatever reason you might need that ;)

For both ways you will need the dumps, you get them here:
http://dumps.wikimedia.org/dewiki/latest/
The main dump is the pages-articles.xml.bz2 if you want the categories as well, you need the
category.sql.gz and categorylinks.sql.gz too.
The pages file is quite huge and will take you probably about 4 hours to download, depending on your connection.

You will also need a fresh and running installation of the mediawiki software.
Install it and here we go:

Migrate to Mongolab

Recently i ran into RAM troubles on my vserver for some reasons, i encountered the evil:

Cannot allocate memory at ...

So first i suspected mongodb to use up loads of memory as top showed.

But after some recherche work i learned mongodb only -seems- to use a lot of memory.
see here and here and here
The actual usage was around 20mb RAM, so mongodb was innocent.

The true RAM monsters were some apache and php-fpm zombies, but thats another story.

While suspecting mongodb i thought about outsourcing the mongodb and i found a free and sufficient offer in mongolab.
My interests were on and i gave it a try.
The free version has a limit for up to 240MB storage and since my app is just a small counter it should last for some time.

[Symfony 2] Security Bundle: Set User Locale on Form Login

[UPDATE]
A recent update to this article may be found here: https://nerdpress.org/symfony-2-set-default-locale-on-form-login-2/

Das Security Bundle ist ein wenig magisch. Da muss man eine HTML-Form definieren, der Rest wird irgendwie konfiguriert (Namen der Post-Parameter wie “_username”, “_password” etc., den Redirect zum Referrer, Remember-Me Funktion und so weiter, das alles wird von der Firewall intern geregelt. Man muss nur eine Login-Route definieren, einen Stub-Controller + Action-Callable (der aber nie ausgeführt wird, weil die Firefall sich davorhängt), fertig.

Das ist angenehm einfach, solange man keine Fragen stellt. Aber wie führe ich zusätzliche Aktionen direkt nach erfolgtem Login aus, ohne Einfuss auf den Code des Security Bundles zu haben?

jQuery .scrollToViewPort()

yesterday i found this very useful jQuery-script on github:

https://gist.github.com/853841

jQuery.fn.scrollToViewPort = function(animTimeInterval) {
  animTimeInterval = (typeof animTimeInterval == "undefined")?"slow":animTimeInterval;
  return this.each(function(){
    $('html,body').animate({scrollTop: $(this).offset().top},animTimeInterval);
  });
}

it moves the users’ viewport to show the element that it has been called on.

I modified it somehow so that it will check now if the element is already in the viewport.
So we can avoid auto-scrolling in that case.
A offset Parameter has also been added in case we need some margin.

https://gist.github.com/1018842

jQuery.fn.scrollToViewPort = function(options) {
  var animTimeInterval = (typeof options.interval == "undefined")?"slow":animTimeInterval;
  return this.each(function(){
    var offSet = (typeof options.offset == "undefined")? $(this).offset().top : options.offset;
    if( $(this).offset().top <= $(window).scrollTop() || ( $(this).offset().top + $(this).height() ) >= ( $(window).scrollTop() + $(window).height() ) ){
      $('html,body').animate( { scrollTop: offSet }, animTimeInterval );
    }
  });
}

usage:

 $(this).scrollToViewPort( { offset : ( ( $(this).offset().top + my_custom_offset ) - $(window).height() ) } );
