Choosing to use Linux means approaching a door through which is a deeper understanding of how computers work. In my opinion, completing a LFS project, or at least understanding what happens in a LFS project, is like a capstone to the sentiment in the first sentence.

On earthquakes, lakes and sensors
I live in Mexico City, one of the largest cities in the world. As all large cities, it has its ghastly demons. I am willing to argue that the one lying below it makes it unique in the world — We live atop what remains of a lake. Of course, it is not visible at plain sight (I would not surround it in this mystery setting otherwise): Our city is not Amsterdam or Venice, embracing the water, but we seem to hide it as if we were ashamed of it — there is a small surviving fraction of the once great Texcoco lake in the city’s South East, in the touristic Xochimilco borough, plus a wider region in the North East that just refused to go away, but has been historically shunned by everybody.
The lake, however invisible, is far from dry: Although it is mostly mud, it does contain some water pockets that are harvested to help our 22 million people have running water. That, of course, together with an impressive set of aqueducts bringing water from over 400Km away.
FPGA Setup: Interfacing with an External Circuit
For this post I will walk you through a project with a Field Programmable Gate Array (FPGA), which was interfaced with a hand constructed clock circuit (an astable multivibrator).
ElectroEuro: A Virtual Coin that Enables the Exchange of Green Energy, Driving a Cleaner and Decarbonized Europe
In 2017, General Electric (GE), one of the largest American companies that specializes in oil and gas, healthcare, aviation and software development, and Eurelectric, the union of the electric industry in Europe, partnered to create an Ecomagination Challenge hackathon. Ecomagination refers to “GE’s growth strategy to enhance resource productivity and reduce environmental impact at a global scale through commercial solutions for our customers and through our own operations”. The focus was on building digital solutions to help decarbonize energy and transportation in Europe, and the hackathon was held in Berlin between June 12-13, where over 100 participants from around the world came together to compete on solving the two challenges presented: Electrification and Advanced Manufacturing.
