CLI Commands in Emacs

A few months ago, Gabriel Gonzalez wrote an excellent article on creating useful tools with Haskell. He used an example of a small CLI tool that aligns the equals signs of a multi-line text input. The article wrapped up by integrating this tool into vim. I love the overarching concept in the article: create small tools that are useful in multiple contexts. It's directly inline with the Unix philosophy. The only problem is that I am an Emacs user.

Hierarchies In a Hakyll Blog

Creating hierarchy in a blog is a useful technique. It allows you to have different sections by type of content. It lets users navigate by their interests quickly. It makes your blog organized. My need for a hierarchy came when working on another blog - Daily Reading Notes. That blog involves notes on books I read daily. Since each book has multiple reading notes, I wanted to allow two forms of navigation: by a grouping of all notes for a particular book and by posted date.

The Right Abstraction for Lambdas

Serverless functions are a great alternative for many light tasks that would traditionally required a server. They allow you to split up work across mutiple small functions, and you only pay for what you use. On top of that, they require less maintenance than managing your own server or Kubernetes cluster. However, the single function per lambda approach can become too granular. Shared functionality becomes hard to group together. You only have hard to enforce naming convention for lambda that belong together.

Making Redux Easy

React and Redux are a top choice for front end projects. React provides fast performance, easy ways to create shared components, and a plethora of libraries. Redux lets you simplify state management in your application, but it has serious drawbacks. In large projects, Redux bloat your project with repetitive code. To support a single store update, you need to create a reducer that handles an action type which is dispatched from an action called inside a component.

Introducing Daily Reading Notes

Recently I ran an experiment of posting daily reading notes on this blog. This was very much a personal experiment. Making these posts every day reinforced my reading habit. I felt motivated to set aside time to read, and I got the chance to reflect on my reading. It also provided the opportunity to share more with others. I plan on keeping this habit going, but this blog isn’t the right place for it.
