Stop using JWTs!

TLDR: JWTs should not be used for keeping your user logged in. They are not designed for this purpose, they are not secure, and there is a much better tool which is designed for it: regular cookie sessions.

If you've got a bit of time to watch a presentation on it, I highly recommend this talk: https://www.youtube.com/watch?v=pYeekwv3vC4 (Note that other topics are largely skimmed over, such as CSRF protection. You should learn about other topics from other sources. Also note that "valid" usecases for JWTs at the end of the video can also be easily handled by other, better, and more secure tools. Specifically, PASETO.)

A related topic: Don't use localStorage (or sessionStorage) for authentication credentials, including JWT tokens: https://www.rdegges.com/2018/please-stop-using-local-storage/

The reason to avoid JWTs comes down to a couple different points:

The JWT specification is specifically designed only for very short-live tokens (~5 minute or less). Sessions

Resolving the "Can't Find the Specified File" Folder Rename Bug in Windows 11

It is a notoriously frustrating system bug: you create a new folder in File Explorer, type out a new name, hit Enter, and immediately get slammed with a prompt stating, "Can't find the specified file. Make sure you specify the correct path and file name."

Ironically, executing the exact same rename operation via cmd or your terminal works flawlessly. The underlying file system is perfectly intact, but the graphical shell's directory rename handler is completely broken.

Here is a breakdown of exactly why this happens and the surgical PowerShell fix to resolve it.

The Software Factory Playbook — Dex Horthy's 4-gate workflow as a skill

A Claude Code Agent Skill built from Dex Horthy's (HumanLayer) playbook on David Ondrej's podcast.

"Once the model has written thousands of lines of code, it is harder to change. The sessions that generate design docs are context-light — you get the most model intelligence when you do the hard thinking early."

By default, agents build horizontally: all the backend, then all the frontend, then a 2,000-line diff lands in your lap and reviewing it is your problem. This skill flips that. Every decision that matters gets made before the code exists — where changing your mind costs a sentence, not a rewrite.

Rust → Odin porting guide

You are translating one Rust file to Odin. Read this whole document before writing any code. The goal of Phase A is a draft .odin next to the .rs that captures the logic faithfully — it does not need to compile. Phase B makes it compile package-by-package.

This guide is project-agnostic. If you are porting a specific codebase, fill in the "Package map" table below with your crate→package layout before starting — everything else applies generally.

	Supported layouts discovered from Unity installers:

	* Legacy 2020-2022: 4-byte flagged raw-LZMA1 chunks. The decoded NSIS
	instruction table starts at 0x1b74, uses 36-byte records with opcode in
	field 0, and field 3 is the compressed data-chunk offset. Each data chunk
	expands directly to one file; there is no extra record-size word.
	* Unity 6000: 3-byte raw-LZMA1 chunks, an eight-byte declared-size header
