Upgrading this blog again

Web development is the skill that irritates me the most. It has improved over the years. The tools available today are far superior. But, I only glimpse at better web design skills. I often times struggle to understand why some websites look the way they do. Even with full access to their source code, replicating them isn’t always evident. There are HTML & CSS tricks I refuse to practice in the aim of simplifying what I imitate. That means some layouts don’t look exactly the same.

Setup up a Bitcoin Lightning point of sale in Common Lisp

Because I can, I recently added support for testnet Bitcoin Lightning payments into this website. The beauty of Freedom and privacy respecting software is that you can do anything you want with it. There are many ways to do it. You can always use a service, provider for that, but the beauty of Bitcoin, the reason it is valuable, is that you can do it yourself.

Why colorize terminal output when you can colorize on the reader?

Colorful text is a must, because we are visual creatures. We process shapes and colors way better than symbols. Confronted to a screen full of text, it is hard to make sense of it, without meaningful coloring. I even find pure text repulsive, I don’t want to look. Command like tools like ls, grep, git offer colorized output, in fact I’m only able to find them useful, when their output is colorful. Color demands attention and focuses it too.
