TypeScript 5.x to 6.0 Migration Guide

TypeScript 6.0 is a transition release bridging 5.9 and the forthcoming 7.0 (a native Go port). Most changes are new defaults and deprecations preparing for 7.0. Here is what you need to do:

Most projects need these tsconfig changes:

{
    "compilerOptions": {
        "types": ["node"],           // @types are no longer auto-discovered (see §1.6)

Terminals should generate the 256-color palette from the user's base16 theme.

If you've spent much time in the terminal, you've probably set a custom base16 theme. They work well. You define a handful of colors in one place and all your programs use them.

The drawback is that 16 colors is limiting. Complex and color-heavy programs struggle with such a small palette.

AGENTS.md

This document helps AI agents work effectively in the X For You Feed Algorithm repository.

Project Overview

This repository contains the core recommendation system powering the "For You" feed on X (Twitter). It combines:

In-network content from accounts you follow (Thunder)
Out-of-network content discovered through ML-based retrieval (Phoenix)

Sandboxing Untrusted Python

Python doesn't have a built-in way to run untrusted code safely. Multiple attempts have been made, but none really succeeded.

Why? Because Python is a highly introspective object-oriented language with a mutable runtime. Core elements of the interpreter can be accessed through the object graph, frames and tracebacks, making runtime isolation difficult. This means that even aggressive restrictions can be bypassed:

# Attempt: Remove dangerous built-ins
del __builtins__.eval

Native Secure Enclave backed ssh keys on MacOS

It turns out that MacOS Tahoe can generate and use secure-enclave backed SSH keys! This replaces projects like https://github.com/maxgoedjen/secretive

There is a shared library /usr/lib/ssh-keychain.dylib that traditionally has been used to add smartcard support to ssh by implementing PKCS11Provider interface. However since recently it also implements SecurityKeyProivder which supports loading keys directly from the secure enclave! SecurityKeyProvider is what is normally used to talk to FIDO2 devices (e.g. libfido2 can be used to talk to your Yubikey). However you can now use it to talk to your Secure Enclave instead!

Pop Note for NotebookLM

Pop Note is a userscript that enhances the user experience of Google NotebookLM by opening the notes in full screen mode with right-click and exit with Escape key. This allows users to focus on their notes without distractions from other UI elements.

Key Features

Adds a right-click context menu option to open notes in full screen mode
Allows exiting full screen mode by pressing the Escape key
Adds a control panel on upper left corner to allow user to change the column layout between 1, and 2 columns.

Most of the source comes from: Steam Beta Forum

Thank you so much to everyone in the forum for contributing, for reaching out to 8BitDo to request switching between XInput/DInput/Switch mode on the dongle, to Valve for adding support on DInput mode, to the SDL developers (and 8bitdo) for adding support on DInput mode, and finally, to the Linux kernel developers for adding support on XInput mode.

This gist summarizes everything from that forum.

Switching Mode

So after the latest firmware update (as the time of writing: Controller 1.06, Adapter 1.04), its now possible to switch to DInput and Switch mode by holding B (DInput) or Y (Switch) while turning on t
