Stop letting Aider code blindly - try this first

Using Aider's /ask and /architect commands to approach larger tasks.

Aider is one of the best AI coding tools available today (in my opinion!). It's a brilliant AI coding assistant that integrates with any LLM, in any code editor.

However, Aider can often feel very eager to make changes. It jumps right into coding after I type anything. I noticed a pattern:

I would describe what I wanted
Aider would start coding right away

JavaScript without npm?
A dive into Rails 7's importmap approach

Using JavaScript in Rails has a very long history. With Rails 7, the latest approach has been to move away from the tools from the JavaScript community like npm, yarn, and Webpack. Instead, Rails 7 introduces importmap-rails as a solution that “embraces the platform” and uses native JavaScript modules (also known as “ES Modules” or “ESM”).

What’s Importmap-rails?

Importmap-rails is touted as a gem that “let you import JavaScript modules directly from the browser” ¹. The documentation claims that “this frees you from needing Webpack, Yarn, npm, or any other part of the JavaScript toolchain.”

At first, I felt like those claims are a bit ambiguous and a bit of marketing hype. After exploring importmap-rails a bit more, I think I have another way of looking at it. importmap-rails is a replacement for npm for app builders. That is: take away npm’s authoring tools (like `

Make WSL2 faster by removing /mnt/c in the PATH variable

Turning off appendWindowsPath (the feature that adds /mnt/c paths to $PATH) can make WSL faster.

For Ubuntu on WSL

For most distros, it can be done by editing /etc/wsl.conf. These instructions were taken from https://gist.github.com/ilbunilcho/4280bd55a10cefef75e74986b6bff936

$ sudo vi /etc/wsl.conf
