Time flows and now it is November. The AOC is coming in just one month. I was checking the first year of AOC I completed back in 2017. When I was working on day 3, I was going to use the AOC map that I had made in the AOC tools I worked on during the last several AOCs.

From Rust 1.80, LazyLock is now part of the stable channel. To be honest, it is the first time I realized the Rust team was trying to stabilize the lazy_static feature. This is great news because I have been using lazy_static in some of my projects, and I am eager to rewrite them using LazyLock (LazyCell).

Last year, I wrote a post titled Re-make my Raspberry Pi after a stupid mistake. A few days ago, my Raspberry Pi screwed up again, and I had to re-make the system once more.

Today is the last day of 2023, and I think I should review how my development has progressed this year.

The AoC 2023 has finished! Just like last year, I am going to record my AoC 2023 journey in this post. This year, I sought a lot of help from my friends in the chatting group we made last year, and the geniuses on Reddit. I truly learned a lot, including several algorithms I had never even heard of before.

I wrote my first elisp mode. I have my code-it-later tool that I find myself using everyday. As an Emacs user, I’ve been wondering if I could call it from inside Emacs, like many other packages. And because I created the code-it-later, it seems appropriate for me to be the one to write this mode for my project.

One day, I wanted to use the format function inside my Rust. I considered writing it on my own, so that others could potentially use it and experience a bit of Lisp (just a tiny bit).

I was trying to play around using my local mac emacs slime to connect the swank server on my raspberry pi. Initially, it cannot work, but I use the ssh tunnel to forward the ports to make it work. However, I try to figure out why it cannot connect directly. It is because the raspberry pi doesn’t open the port.

After a year’s wait, I finally got my M2 aarch64 chip MacBook Pro. And after one day of usage, there are some experiences I should write down about migrating from the old intel macbook pro to this new one.

I noticed open Cargo.toml in my emacs didn’t show colors/highlights one day. After check the error messages, I figured out a new word that tree-sitter.

As I did last year, I decided do AOC this year. I feel it is a bit harder than last year. This is just the journey of 2022 AOC. All code host on here

I am not a Jenkins’ fan in my whole (not long) career. I always feel frustrated when I have to write jenkinsfile or use some other tools based on jenkins.

Several weeks ago, SBCL 2.0.2 updated with a “new” feature called Block Compilation. This is the first time I hear this term, I go collect some information of this new feature and I found this article.

I am trying to learn OCaml several weeks ago. My personal hobbits is writing a tiny project for fun with new language which I am learning. So, for OCaml, I wanna to rewrite my old code-it-later project. At beginning, I just want to practice, then I get some experiments.
