TIL how to add math typesetting to Github Pages with KaTeX

Since I’ve started Andrew Ng’s Machine Learning on Coursera, I’ve found myself with a new need on this blog: the ability to elegantly render formulas. This really showed in my last post on the identity matrix when I had to hack through displaying a simple matrix using code blocks and space-aligned columns and rows of characters. So, my quick win this morning is to find a way to work in LaTeX-like formula rendering for future blog posts and this post is going to serve as my testing ground for adding this capability!

TIL about Concourse fly targets

At work we use Concourse CI for continuous integration and delivery. It encourages interacting with it via the fly commandline interface (CLI). It also requires everyone to log in to it, and be a part of a team, to do a form of role based access control (RBAC). Today, I lost about 30 minutes trying to figure out why my new pipelines weren’t being deployed to the correct team in Concourse. It was because I had set up my fly target incorrectly.

A new album from my favorite DJ

Nicolas Jaar has been my favorite music artist for the past decade. I find I have a deep connection with his music that I haven’t felt elsewhere. The best way to describe it is by comparing it to the phrase “the music fills the room.” I get lost in his music and it makes the space I’m in feel bigger - almost infinite.

On on-boarding

“On-boarding” is defined as the actions required of an organization and newly-hired individual to get that individual to contribute to their potential. When evaluating the ability of an organization to on-boarding an individual, there are two key metrics to focus on: time to first contribution and personal velocity.

Identity is a Continuum

A person’s identity is defined as the totality of one’s self-construal, in which how one construes oneself in the present expresses the continuity between how one construes oneself as one was in the past and how one construes oneself as one aspires to be in the future
