Tools

People often ask me what kind of web tools I use. I do all my research and writing using simple tools installed on a phone or on a laptop. Although laptops have been around for many years, the way we use them changed significantly. For example, my laptops are running rather effortlessly multiple servers as well as blockchain full nodes. This allows designing, computing, and working on data presentation completely on the move. Once you learn how to deploy a simple machine learning model on a server you can easily code an interface to demonstrate how it performs. Apps on the mobile phone and on the laptop are syncing in the background. I try several different apps to see what works best for me.
