Mahdi Yusuf is back with another set of Architecture Notes, this time covering everyone’s favorite “data structure server”, Redis:

Rather than iterating over, sorting, and ordering rows, what if the data was in data structures you wanted from the ground up? Early on, it was used much like Memcached, but as Redis improved, it became viable for many other use cases, including publish-subscribe mechanisms, streaming, and queues.

Excellent prose and super-useful diagrams make this post from architecture notes a 10/10 🏆

Mahdi Yusuf worked a startup in his twenties and wasn’t worried too much about his health. When he quit that job, he decided to take better care of himself and lost fifty pounds. Now, he’s the CTO of Gyroscope, a startup that aims to be the operating system for the human body, but ever since joining, has gained weight back.

Mahdi talks to me about how Gyroscope is trying to help people understand their bodies better, growing up with a love for computers, and trying to be healthy with a busy life.
