Writing a low level C code editor, going down the rabbit hole of gap buffers and piece tables. Fun though.

I first wrote it the dumbest way possible, one big array with padding at the back. Worked fine actually for most modern use cases, but as this is also a learning experience, I want it to be best in class in performance.

I think I'll settle on gap buffer because the performance is great and it doesn't hurt my head.

Rebuilding a Ford Cleveland V8 - the Australian specific 302 cubic inch version.

One broken engine and one non operational one and turning them into a single good motor. American thin-wall cast V8 engines are fairly similar, but different enough that if you don't get them built you have to do a bit of puzzle solving (especially in the timing case). Plenty of youtube videos and forum posts on the Cleveland and it's been fun piecing it back together and learning about new things like installing cam bearings.

I watched Lex Fridman interview Richard Wolff and have spent 2 weeks going hard into marxist and anarchist theories and practice. Working through 2 books, a dozen browser tabs, interviews, etc. It's rare something catches my interest like this (especially non-technical). But I'm really enjoying all the different perspectives and formulating my own fantasy scenarios.

Do you have any recommendations on books that talks about Leninism like it's foundational ideas, etc. and how it departs from Marxism?

Thanks in advance.

A quick and dirty, shallow one, that I just opted to brute force out of curiosity. An online game I play includes an optional two player Russian Roulette type feature (non-fatal). I got to wondering if there was an optimal betting percentage to use, if you set aside some money as a betting seed. So I spent time coding up a really ugly brute force "just run lots of games and see". Pretty much the answer is you'll lose…

I started looking into the Gospel of Thomas right before the start of the pandemic, which led to a number of rabbit holes: * Turns out the work is not 'weird' or 'Gnostic' but is directly addressing details from Lucretius, including paraphrasing his view of evolution and atomism, but refuting the claim there's no afterlife by basically appealing to the idea we're in a simulated copy of an original physical world wher…

> appealing to the idea we're in a simulated copy of an original physical world where the spirit doesn't actually depend on a body

Sounds a bit gnostic no?

MH370. There was no intermediate step as I saw somewhere it was the 10th anniversary of its disappearance and decide to get a quick update on the current status of all the evidence and theories. Ended up spending the entire day reading about radars, pings and aviation controls.

What did you find is the most reasonable explanation?

Pilot suicide by a long shot. There is no other alternative theory that comes even close.

What was interesting is to see them piece the theory together from the very fragmentary and little evidence (what is even more mind-blowing to know how little evidence there was to play with given we are talking about a 747).

The true mystery left is how did he execute the suicide and why. How did he dispatch the co-pilot? (There was a very small window to do so). What did he do in the final hours (was he alive for the entire duration)?

I switched to Neovim from Sublime Text after trying copilot in Sublime, feeling sad, and then watching The Primeagen and his glorious mustache for too long. Ostensibly I wanted to be able to code on the production server like a miscreant with the same tools as my laptop. However I just wanted to regain command of my dev environment after years not coding. I also reorganized the furniture in my office and got weirder…

So, how was the switch to Neovim? Which plugins did you settle on?

I used nvchad and I am configuring it from there. Here’s my fork.

Overall I still think I am faster in sublime text. I get stuck in the different modes. I find shift select and grep to be pretty frustrating.

However I will muscle through this. Every challenge is another set of vim stuff to learn. I have faith I will love it later.
