A pacer is an experienced runner that commits to other runners to run a race or a section of it in a predefined duration or speed. They also help with mental support for those who are struggling to stay out of their comfort zone. Many races have pacers, but not all. The ones that have attracted many runners looking for some help with their personal goals, like getting a new personal best, finishing a marathon under 4 hours, or even qualifying for Boston. But can we fully trust them to deliver what they committed to?

A good deal of being a geek is to code or understand coding. We love objectivity and hate subjectivity, so coding is the ultimate objectivity sophistication. If something can be expressed in numbers and logic, then code is the best way to materialize and document it. That’s why we created a programming library where we can express all the calculations related to running and let other geeks use and contribute to it.

8 years ago I failed to write a book. I wrote it until chapter 3 but I couldn’t stand all the criticism coming from the editor and the reviewers. As the deadline to deliver chapter 4 was approaching, I was still overwhelmed by all the work to catch up with their feedback. So, I quit, but I learned something very important from that experience: the scrutiny over the writing of books makes them very good references.

A year ago I wrote an article about my Knowledge Portfolio in 2022. Indeed, knowledge is an investment, but I changed my mind about diversifying it. At the time, I described the domains, the programming languages, and the projects I planned to spend time with. To this day, some of them flourished and others failed. Since time is a valuable asset, spending it with a limited set of subjects will lead to mastery sooner. I’m trying to downsize this year, so let’s talk about what happened in 2022 and what to expect in 2023.
