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

The pages file is quite huge and will take you probably about 4 hours to download, depending on your connection.

Migrate to Mongolab

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.

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

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.

Synchronous http request in node.js, that you dont want, probably

Achtung dummy code!

…and so it goes Asynchronous:

 for(var i = 0; i < loop.length; i++)
 {
	var proxy = http.createClient(PORT,SERVER);
	var request = proxy.request('GET', url, 
        {
            "host": SERVER
        });
	request.end();
	...
 }

fire, fire, fire, fire

… and so it dont, Synchronous then:

var proxy = http.createClient(PORT,SERVER);
 
for(var i = 0; i < loop.length; i++)
 {
	var request = proxy.request('GET', url, 
        {
            "host": SERVER
        });
	request.end();
	...
 }

point – shoot, point – shoot, point – shoot
