Welcome to Kaoru’s Blog!

When using Emacs, have you ever thought, “I wish I could edit just a part of this file in another window…” or “I’d like to compare the same content with different display modes…”? I certainly have, many times. That’s when I discovered and was impressed by the Indirect Buffer feature! This post explains the basic concept of Indirect Buffers, how to use them, and some points to keep in mind....

Introduction Are you an Anki user? Anki is a powerful memorization tool that utilizes a spaced repetition system (SRS). I’ve been a long-time Anki user, and it’s become indispensable, especially for language learning. Recently, while using Anki for English vocabulary learning, I had an idea for the “perfect” card type – one with features I’d always wished for. I’ve now realized this ideal card type and made it publicly available on GitHub....

The Problem The other day, when I started Emacs as usual, the following message appeared in the minibuffer: Project <Project Name> at <Project Path> cannot be read. Emacs then became a piece of software that simply displayed a white screen. I had recently changed the path of this project, so I suspected that might be the cause. I tried modifying/deleting the project path in projectile-known-projects-file, but the situation didn’t improve. I also tried commands like doom sync and doom upgrade, but none of these resolved the issue....

The Problem So, I recently fired up Emacs to do some Julia coding after a while, and I ran into this annoying message: Server julia-ls:50759/starting exited (check corresponding stderr buffer for details). Do you want to restart it? (y or n) It kept popping up (even if I pressed y), and LSP just wouldn’t start. It took me a bit of time to figure this out, so I’m leaving this note here for anyone else using Julia in Emacs....

Yo, Happy New Year, peeps! Last year, I was on that grind, tackling the 2023 Advent of Code bit by bit. So, I’m droppin’ my solutions and some quick notes here, ya dig? I’m coding all this in Python, straight up. I’m thinkin’ of droppin’ the whole thing on GitHub when I’m done, but no promises on when that’ll be, ya feel me? Aight, let’s jump into Day 1’s solution, no time to waste....

Introduction Hey everyone! I regularly use anki-editor to create Anki cards. But after upgrading Emacs, my math formulas started looking really messed up. Specifically, I had these two problems: In the desktop Anki browser’s preview for each field, the formulas weren’t rendering as formulas. They just showed up as plain LaTeX code. Formulas were being displayed as PNG images. (They used to be rendered inline with MathJax.) Since I rarely edit cards directly in the desktop Anki app, the first issue was somewhat tolerable....

The Problem I was trying to use Org Cite Citations and the following code to display my references: #+print_bibliography: But only the “References” header showed up – the actual list of references was missing. I checked the generated Markdown (.md) files in my content/ directory, and the reference list was there in HTML. However, when I looked at the final HTML files in the public/ directory, the references were gone....

Whassup, peeps! It’s been a minute since my last post (shoutout to the one person probably reading this, you the real MVP!). My Master’s thesis, with some fresh updates, just dropped on arXiv. Check it: Paper: Babasaki, K., Sugasawa, S., McAlinn, K. and Takanashi, K. (2024). Ensemble doubly robust Bayesian inference via regression synthesis. (arXiv:2409.06288) So, this paper, it’s all about takin’ this ensemble method called Bayesian Predictive Synthesis (BPS) that Professor McAlinn cooked up, and flexing it into the world of causal inference, specifically for estimatin’ Average Treatment Effects (ATE)....

Question a Make up a nonmathematical function that is one to one but not onto. b Make up a mathematical function that is one to one but not onto. Answer a “The student number of” from Keio University students to integers. b \(f(x) = 2^x\)

Question Explain Why one of these statements is true and the other is false: \begin{align*} (\forall \text{ man } M)(\exists \text{ woman } W) \mid W \text{ is the mother of } M \\ (\exists \text{ woman } W)(\forall \text{ man } M) \mid W \text{ is the mother of } M \end{align*} Answer The first statement is true, and the second is false because every man has a mother but there doesn’t exist a woman who is the mother of all men....
