Configuration of this is beyond the scope of this post, but installation through yum or apt-get should be sufficient (or equivalent on a Windows or Mac). To pull the duration of a video from any machine with FFMPEG and Python […]

To understand more about the fuse settings for your microcontroller, visit Engbedded’s AVR Fuse Calculator. To write fuse settings, you will need a programmer with this capability. I use Mighty Ohm’s high-voltage rescue shield available here. Arduino […]
In need of an IP address on-the-fly that appears to be valid? Try this: from random import randrange def generateIP(): blockOne = randrange(0, 255, 1) blockTwo = randrange(0, 255, 1) blockThree = randrange(0, 255, 1) blockFour = randrange(0, 255, 1) print ‘Random IP: ‘ + str(blockOne) + ‘.’ + str(blockTwo) + ‘.’ + str(blockThree) […]
