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.

OXID eshop routing

If you wonder about routing in OXID eshops or how the URL structure is here are some hints:

OXIDs MVC, well thats some kind of different naming and you have to get used to:

the M (Model) you find in /core
the V you find in in your templates in /out, there the main view is called the same as your controller, given the controller has a render() method.
/views/details => /out/[templatename]/page/details.tpl
the C (Controller) you find in /views (what? oyerywell!)
like /views/details.php

The routing itself is like so:

Silex Starter Stubs

There are several preconfigured Silex Apps on github. They let you start your Silex project in no time, which is good.
This makes Silex an even more simple rabbithole into the symfony2 world.

I started one myself and had a close look on the others, so i thought i share this.
They all differ a bit so you must choose what fits your needs the best.

They all follow some kind of “best practise” structure, some more, some less.

tell redis db to not persist

redis persists its memory data in snapshot style in every n seconds depending on your configuration.
read more here.
perhaps you would like to use redis as a pure in-memory db, like f.e. memchache.
you can tell redis to not persist and save some bits&miliseconds.
this could be the case when using redis as a f.e. realtime queue, you wont need persistence,
because you could say: nobody needs is newsfeed from the that day before the machine crashed ;)

alright, do so by:

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.

OXID eShop manufacturer long description module and fck editor module

I recently made my first OXID eShop module: OXID-manufacturer-text-mod
Which basically adds a long description field to the manufacturer.

This comes just as a normal textarea, as usual in OXID CE.
If you would like to add an Richtext Editor, you can purchase the fck Editor module
and install it, if you did not already.

After you installed the fck module your textareas of the basic shop are rich text.

But since the manufacturer long description comes from the module, you have to teach the fck module the new field.
