Core Philosophy

Why did you do this?

Relax, I only have one Sunday to work on idea, literally my weekend project. So I tried Deepseek to see if it can help. Surprisingly, it works and it saves me another weekend...

What is your setup?

Just chat.deepseek.com (cost = free) with prompts adapted from this gist.

Does it work in one-shot or I have to prompt it multiple times?

Under the Hood: How gptel Manages LLM Conversations in Emacs

If you've used Emacs to interact with LLMs, you've probably encountered gptel. While it appears simple on the surface—just another chat interface—its internals reveal an elegant approach to managing LLM conversations that leverages Emacs' text property system. Let's dive into how it works.

Visual vs Actual: The Prefix Illusion

One of the first things you notice in a gptel chat buffer are the prefixes—typically "### " for user messages in Markdown mode or "*** " in Org mode. What's interesting is that these prefixes are purely cosmetic. They're stripped out before any API calls using a simple but effective mechanism:

(defsubst gptel--trim-prefixes (s)

Lima Cheatsheet for macOS

I stumbled on an incredible open source solution, Lima. In some ways, it has some of Hashicorp's Vagrant's resemblance, but in my opinion, it's so much superior in many ways as it doesn't use external dependencies such as Oracle's VirtualBox.

If you're used to docker on the command line but wanted to play with VMs rather than containers, then this is for you! No need to fuss with cloud-init as a user account (using your existing username in whoami) with a proper home directory would be auto-generated for you with full passwordless sudo privilege. SSH access to the VMs from the host is seamlessly integrated as well.

This quick guide is for those who need to set up virtual machines with modern Linux OSes (only few selected OSes are best supported) from scratch using only the command line. You can have a VM up and running within minutes from absolutely nothing.

NOTE: This was last tested using:

Anti-hype LLM reading list

Goals: Add links that are reasonable and good explanations of how stuff works. No hype and no vendor content if possible. Practical first-hand accounts of models in prod eagerly sought.
