The Problem<\/h2>\n
The error message wasn’t particularly helpful at first glance. “attempt to call method ‘range’ (a nil value)” doesn’t exactly tell you where to look. But after some digging, I realized this was breaking my render-markdown.nvim plugin.<\/p>"},{"title":"Thoughts on 'Metamorphosis'","link":"https:\/\/arcanecodex.dev\/posts\/culture\/books\/metamorphosis\/","pubDate":"Wed, 25 Mar 2026 00:00:00 +0000","guid":"https:\/\/arcanecodex.dev\/posts\/culture\/books\/metamorphosis\/","description":"
Metamorphosis is a fascinating study into human nature. Our protagonist Gregor wakes up transformed into an insect and the novel details his family life after the fact, exploring the question of whether our relationships can ever be truly selfless.<\/p>\n
Note:<\/p>\n
\nI encourage you to read the book before this codex entry. I will be divulging major plot points (and it’s a short read anyways)!<\/p>\n<\/blockquote>\n
Do human beings only form relationships based on mutual gain? Over the course of the book, we see how Gregor’s family relationships unravel as they care for him in his new, incomprehensible, state. Although his parents are initially too shocked with his transformation to even face him, his sister takes the effort to help him as best she can. She cares for her brother. Not only does she try to discover what food his new form will accept, but she takes responsibility for looking after her brother when no one else can. But she becomes resentful of this position. Even though Gregor is internally grateful for her service, he is not capable of expressing his gratitude. Without this feedback, it seems the duty of helping a family member becomes a thankless burden, which everyone becomes annoyed with. They are performing a service out of respect to his former position, not for him now… It’s interesting to explore the idea that maybe if Gregor was able to express his gratitude, his family would provide his care with joy.<\/p>"},{"title":"How a Motorcyle Changed My Life","link":"https:\/\/arcanecodex.dev\/posts\/thoughts\/lifechanging-bike\/","pubDate":"Fri, 13 Feb 2026 00:00:00 +0000","guid":"https:\/\/arcanecodex.dev\/posts\/thoughts\/lifechanging-bike\/","description":"
When travelling across India, I caught the bug for riding. On returning to the UK, I managed to get my full license. I decided not to renew the insurance on my car, leaning fully into the biker lifestyle. Here are some of the ways owning a bike affected my life.<\/p>\n

Owning a car in Central London is not fun.<\/span> It’s difficult to park anywhere, you have to spend money just for driving in the city, and you are 100% going to get stuck in traffic. Because of these reasons, I just didn’t use my car. It ended up being more expensive and inconvenient to get to most of the places I go to.<\/p>"},{"title":"Preparing for a Nomadic Life","link":"https:\/\/arcanecodex.dev\/posts\/thoughts\/nomad-prep\/","pubDate":"Thu, 05 Feb 2026 00:00:00 +0000","guid":"https:\/\/arcanecodex.dev\/posts\/thoughts\/nomad-prep\/","description":"Soon enough, I’ll embark on a journey.

Although working for yourself has a myriad of benefits, there is a large hurdle that one must overcome to avoid wasting such an amazing opportunity: lack of structure. When you work a regular job, you have to show up at the same time everyday. Your routine becomes forced upon you, but nonetheless, you have a routine.<\/p>\n
But when you start taking your own path, such restrictions don’t exist. You can book client meetings at any time you like, start work at 4am or 4pm, and can work intermittently throughout the day. As long as you are making enough to satisfy your income requirements and goals, you can work 1 hour a day or 20. Here are some difficulties I have had with managing this new lifestyle and some insight into how I manage this.<\/p>"},{"title":"Thoughts on 'The Shining'","link":"https:\/\/arcanecodex.dev\/posts\/culture\/movies\/the-shining\/","pubDate":"Thu, 15 Jan 2026 00:00:00 +0000","guid":"https:\/\/arcanecodex.dev\/posts\/culture\/movies\/the-shining\/","description":"

Today, there are many ways to achieve the same goal. When writing code, for example, one can use a fully equipped IDE like IntelliJ, something super lightweight like Vim, or, if you are really mad, Notepad++. You could\ndedicate hundreds or thousands of hours switching between different tools, experimenting and starting from scratch every time, and still not find something that really works for you. I believe that a true\ncraftsman of any discipline needs to invest in their tools.

AI has democratised writing code. Pretty much anyone can pull up ChatGPT or Claude and build basic apps and\nwebsites. What people fail to realise is that writing code is just a small part of being a developer.<\/span> Indeed, in most software engineer roles, writing code is one of the things you spend\nthe least time on!
