Claude Code runs tools and shell commands on your behalf. Launched from a terminal, the CLI inherits your shell environment and everything just works. But under Claude Desktop, Claude Code is spawned from a GUI/desktop session that never sourced your interactive shell config—so if you rely on version managers like mise, asdf, or nix, the tools they install may not be on Claude’s PATH. The fix is a single setting: CLAUDE_ENV_FILE.
A monoid is one of the smallest useful abstractions in algebra: a set closed under an associative binary operation, with an identity element. That simplicity is exactly why it shows up everywhere—from summing numbers and concatenating strings to powering divide-and-conquer algorithms and elegant data structures like finger trees. This post walks through what monoids are, why they give you “compute power” for free when you can phrase a problem in terms of them, and how to think about choosing the right monoid and predicate when you do.
I’ve moved most of my small scripts to Bun. It sidesteps Windows’ lack of shebang support and the Git-for-Windows/WSL bash dance, and gives you one runtime for both ad-hoc shell-style commands and full scripts.
You can get tmux session persistence and multiplexing in Windows Terminal by running tmux inside WSL and setting the default shell to PowerShell. New panes and windows will then start pwsh.exe instead of a Linux shell. Here’s a minimal setup using small wrappers and the tmux -C attach trick to configure new sessions.
When working with Git repositories, there are often files that need to be backed up but shouldn’t be committed to the main branch. These might include local development settings, IDE configuration files, personal notes, or development scripts that are specific to your workflow. The challenge is finding a way to back up these ignored files without polluting the main repository history.
When using mise with Cursor, you may notice that the mise environment is not activated when Cursor executes shell commands. This occurs because Cursor launches a non-login shell, which initializes differently than an interactive login shell and therefore does not automatically source your usual mise setup.
I miss the feature in readline (Bash/Zsh) where Ctrl+x, Ctrl+v switches to Vi command mode temporarily. In that workflow, entering Insert mode switches back to Emacs mode. PSReadLine has a command ViCommandMode, but binding it directly in Emacs mode will report errors on every key input. The solution requires handling the mode change event to toggle the global EditMode between Emacs and Vi.
I’m reading Linear Algebra Done Right by Axler and found the section on quotient spaces difficult to understand, so I researched and took these notes. Definitions 3.95 notion: $v + U$ Suppose $v \in V$ and $U \subseteq V$. Then $v + U$ is the subset of $V$ defined by…
This post explains how to set up a static site on Cloudflare R2. I recently migrated my blog to Cloudflare R2, and the process went smoothly until I encountered R2’s lack of native support for rewriting URLs to index.html files. This post explains how I resolved this issue.
This article explains the paper [Herlihy, 2018]1 in simple words. In the paper, Herlihy has introduced an effective atomic cross-chain swap protocol in order to exchange assets across multiple blockchains among multiple parties.
