Já napíšu jeden řádek a ukradnu všechny soubory v autoindexovaném adresáři na web serveru (nevím přesně jak se tomu vlastně říká - příklad bude zřejmě názornější). Než mě začnete kamenovat, zamyslete se nad tím, jestli každá stařenka, která umí uštrikovat kuklu je automaticky zloděj…

Nebyl bych to samozřejmě já, kdybych si to nepřidal do kontextového menu Opery…(pokráceno)

There was one thing I missed most while using Pidgin - a simple plugin, which pops a random status message on Pidgin start after given time interval. I loved this plugin I’ve seen first in Miranda so much that  I decided to astray to terra incognita - plugin writing and Perl. Well it took me couple hours to figure out how it works and to learn the basic Perl syntax, nevertheles I’m happy to anounce that “randomator” is ready for downloads now…

 INSTALLATION

Simply unpack the archive to your ~/.purple/plugins directory and paste your own messages into file named randomator.txt. Each line of this file is considered to be a message. After strarting Pidgin go to plugins menu (ctrl+u) and enable the plugin. You will also need to create a “new status” with some content in order to let the plugin change the messages..

 USAGE

 Well, the plugins looks after itself, so you don’t need to do more stuff. I guess I should make some preference dialog to set your own path to the message file, but I was kinda lazy to that.

SETTINGS

You can specify the interval between message change on line 47 in randomator.pl file Purple::timeout_add($plugin, 3600, \&set_message); The preset interval is 3600 seconds = one hour.

My hosting was damn slow today so I decided to yell at some poor guys out there to get some speed. It’s allways better to have some arguments on you so I thought that showing some numbers would be fine. To demonstrate how slow my domain is I decided to compare the time needed to obtain my page with time needed for getting page from Seznam.cz. You are probably starting to laugh at me just now. Why should I do this for? It’s comparing like comparing elephant’s poo with safe water. No match? Correct :> I will share the code nevertheless just for fun. So let’s get started, shall we?

We need a simple function which handles the HTTP request:

And now we just loop thru URIs within argv and run the Timer.repeat() method on each one. Note that we have to import the fetch_page function in setup argument in order to use it further in the stmt. The repeat method calls timeit method with number of iterations specified as it’s second argument and repeats this first_argument*times. The minimum value of all measured is printed out.

If you ever came across Dicosgs, you probably realized, how useful this site is when it comes to mining information about audio releases. This very lame tutorial will demonstrate using Discogs API & python to get release information, parse it and serve release bbcode to Apache.

Parsing a bit messy HTML is as useful as a chocolate teapot, so we better use the API, which implements RESTful interface and therefore provides better output - XML. Before we start you will need to obtain an API key.

Well… we need to import some stuff in the beggining

For a starters we can write a simple function to fetch desired XML:

def get_release(release_id):
     global error
     REQUIRED_PARAMS = ‘f=xml&api_key=’+YOUR_API_KEY
     request = urllib2.Request(‘http://www.discogs.com/release/’+str(release_id)+‘?’+REQUIRED_PARAMS)
     request.add_header(‘Accept-Encoding’, ‘gzip’)
     try:
          response = urllib2.urlopen(request)
          data = response.read()
          return gzip.GzipFile(fileobj = cStringIO.StringIO(data)).read()
     except urllib2.HTTPError, e:
          error = ‘Ooops. An error occured Are you sure that "’+release_id+\
          ‘" is an existing release id?\n\nHTTP ‘+str(e.code)+‘\nRequested URI: ‘+query_string
     return False

As you see the function makes a request string out of the release id and your API KEY and requests the page from discogs. The response is deflated XML with our desired data. On any HTTP error it saves the error string into global variable error and return False.

And now comes the parsing. I’m used to SimpleXML extension from PHP so i used SimpleXML module (and command-line tool) by Ales Smrcka.
A simple fucntion for parsing the XML:

We send our XML to SimpleXML and create empty dictionary for our release data. Now we need to parse the XML with SimpleXML:

As you see you can get any item by using elements() method. All you have to do is walk thru all elements using for loop with range() and store data somehow… The last portion of the function makes the final bbcode:

The final part handles release id parameter obtain via GET and flushes the bbcode back to the browser (or more likely to some AJAX widget):
