I now have some time and after some holidays the need to code new stuffs is back.

The lamson project (a python SMTP framework) seems quite interesting. It might be my new pet project since I have a need for a customizeable SMTP server. It might also be the good starting point for the PBEM/Internet version of Carcassonne I always wanted to do.

linuxfr en a parlé, je l'ai testé ! OpenTTD est la ré-écriture, sous GPL, de Transport Tycoon Deluxe.

OpenTTD c'est aussi, au delà d'un nom barbare, une véritable invitation à la glande : qu'est-ce que j'ai pu perdre comme temps à résoudre des problèmes de signalisations ces derniers jours !

Je me console en me disant que quelque part, c'est un peu comme un problème d'accès concurrent à des ressources limitées et que donc je fais de la programmation.

In order to play with other to a blind test music game, I created a small pygame script that plays a song and wait for the player to press a button, wait for its response and display the artist/title of the song. It was my first experiment in game programming and pygame made it very easy.

To make it more fun, I decided to use my wiimotes as input devices. Gathering information from the GNU/Linux Port for the Wii and a script from Cadex found on the web I created this piece of code to send wiimote events to pygame.

class Wiimote(object):
    wii_buttons = {'A1300008': 'A', 'A1300004': 'B'}
    def __init__(self, address, event):
        self.event = event
        self.address = address
        self.status = "Disconnected"
        self.receivesocket = bluetooth.BluetoothSocket(bluetooth.L2CAP)
        self.controlsocket = bluetooth.BluetoothSocket(bluetooth.L2CAP)
        self.connect()
    def connect(self):
        self.receivesocket.connect((self.address, 0x13))
        self.controlsocket.connect((self.address, 0x11))
        if self.receivesocket and self.controlsocket:
            if self.event == WIIMOTE1:
                data = "521110"
            else:
                data = "521120"
            self.controlsocket.send(data.decode('hex'))
            self.status = "Connected"
            thread.start_new_thread(self.receive, ())
    def receive(self):
        self.receivesocket.settimeout(0.1)
        while self.status == "Connected":
            try:
                data = self.receivesocket.recv(23).encode('hex').upper()
                if data in self.wii_buttons:
                    event = pygame.event.Event(self.event,
                                               button=self.wii_buttons[data])
                    pygame.event.post(event)
            except bluetooth.BluetoothError:
                pass
        self.receivesocket.close()
        self.controlsocket.close()
        self.status = "Disconnected"

What this class does is creating two sockets to communicate with the wiimote located at address. Once the connection is established, we send a simple command to light the led on the joypad and we create a thread that will receive all the data and post the events comming from the pad to the pygame event loop.
