I recently came across Traefik. It is a reverse proxy built specifically for services in the cloud. I was searching for a convenient (up-to-date) way to expose my project using a reverse proxy within docker-compose. I used to use nginx for this, but it then requires a generator and an lets encrypt listener (so 3 containers). Traefik only requires a single container and allows you to label your docker containers to apply rules to them. ...
This is my first article in a series called Rock Solid Software. In it I explore different dimensions of software that does not simply break. You can write good software in any programming language, although some are more suited to a disciplined practice then others, Clojure is definitely in the relaxed space of discipline here. Today I am exploring the use of Selmer templates in Clojure. If you have explored Biff at all you will know that all the UI logic works by sending Hiccup through a handler, which will turn into HTML through rum (specifically the wrap-render-rum middleware). If you provide a vector as a result for an endpoint, it will be converted to HTML. ...
I ❤️ to build software. I sadly do not have a lot of time next to my daily work to spend on my side projects, so I have to be disciplined in where I invest time. I wish I could spend endless amounts of time on exploring new technologies, but sadly I simply do not have that time. In writing this is sometimes referred to as “to kill your darlings”. Sir Arthur Quiller-Couch wrote in his 1916 book On the Art of Writing: “If you here require a practical rule of me, I will present you with this: ‘Whenever you feel an impulse to perpetrate a piece of exceptionally fine writing, obey it—whole-heartedly—and delete it before sending your manuscript to press. Murder your darlings.’” ...
This is a longer form article. I is relevant as of February 18th 2023. If the circumstances of my environment changes I will try to update this article to reflect the situation. You can find the full source code of my dotfiles on Github. I like consistency and simplicity. I do not like to use many different tools to do different things, I rather spend my time learning to use a few tools very well then to follow the hype on the latest trend of tools for something we have been doing forever. ...
Let me tell you how it was to ship a product out to half a million people back in 1999. But before I do that, let me tell you why. Today I talked to one of my students and he mentioned that he was very nervous about a change he was making. He was afraid it would break things and that he would spend the afternoon working through his CI/CD pipeline to resolve issues. ...
