Created March 23, 2011 15:20
Creates a md5 hash using every file in a given folder
#Returns the md5 hash for every file in folder 'folder', except if the
#file is named 'md5' (because that means the folder already contains a md5
#hash)
def md5_for_folder(self,folder, block_size=128):
md5 = hashlib.md5()
for root, dirs, files in os.walk(os.path.join(folder)):
for f in files:
if f!="md5":
fp = open(os.path.join(folder,f),'r')

Android accelerometer polling, just the creation and update portions. Updated the class to implement SensorEventListener, since SensorListener is deprecated
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
sm = (SensorManager) getSystemService(SENSOR_SERVICE);
accell = sm.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
setContentView(R.layout.activity_main);
xacc = (TextView) findViewById(R.id.xvalue);
yacc = (TextView) findViewById(R.id.yvalue);
zacc = (TextView) findViewById(R.id.zvalue);
