It's time for some Python GPIO programming with Raspberry Pi and pyMCU

Mini computer like Raspberry Pi or a board with a microcontroller called pyMCU allow us to use various electronic components via GPIO headers. Using some Python code we can turn on a LED, write some text to an LCD display or even make a robot, digitize signal from various sensors.

In the upcoming weeks and months I'm planning various Raspberry and pyMCU related articles describing my GPIO codding. For Raspberry some addons are already on the list - Gertboard, 4D Systems display (uLCD-24-PTU-PI), some leds, buttons, numeric keyboards, LCDs and stuff like that.

Image optimization with Python and web services

Image optimization is a broad topic. Image can be converted to different file formats, resized and so on. All for saving bandwidth and decreasing time needed to load all elements of a webpage.

But what if we have an image that is ready to be posted on a web page by a user that isn't an expert? What tools can we use to automatically optimize uploaded images? In this article I'll go over few Python and service based solutions for image optimization.
