As a second-semester student in systems and digital media at the Federal University of Ceará in Brazil, I was given the assignment to remake the classic Atari 2600 Breakout game from 1978. I am still in my infancy in learning software development, and this was a challenging experience.

Neousys’ rugged “IGT-22-DEV” IoT gateway runs the open source Linux “ThingsBoard IoT” stack on a TI AM3352 with PoE PD, DIO, serial, USB, and mini-PCIe with uSIM.

My wife and I moved into a new home in October 2020. As soon as it started getting cold, we realized some shortcomings of the home's older heating system (including one heating zone that was always on). We had Nest thermostats in our previous home, and the current setup was not nearly as convenient.

Devs told if they really, really, need more time for merges they can have it Linux overlord Linus Torvalds has revealed that inclement weather in the USA meant he recently endured six electricity-free days in his Portland, Oregon, home during which he was unable to tend to the kernel.
