Linux + Meta Quest 3S

2025-04-27: The way I play VR games wirelessly on Linux e.g. from Steam is to use WiVRn (a fork of Monado) via the Envision orchestrator.

Here's the path I followed to get it working with my Meta Quest 3S:

  1. Download the appImage as linked from the Envision page of the Linux VR Adventures wiki.

  2. Launch Envision from the terminal (so that you can see its console messages). In the GUI at the bottom is a combo box. Select WiVRn as the desired system. Then at the top of the GUI is a button to configure and build it. You will likely need to apt install some prerequisites first. (2025-04-23) Envision wanted me to installed these packages for Lighthouse profile:

    sudo apt install libeigen3-dev glslang-tools glslc libbsd-dev libdrm-dev \
    libusb-1.0-0 libusb-1.0-0-dev libx11-xcb-dev libxcb-

Hacking HY300 Pro+ Projector (720p)

Hello manufacturer. Good device. But software we want to customize. If you allow, we will buy more.

Despite being advertised as "4K 1080P", it really downscales those to 720P.

But for 28.50 EUR from Amazon Warehuose Germany in 2025, one can't exactly complain. https://www.amazon.de/dp/B0DSP74YQW

Chengdu Hotack Technology Co., Ltd. is the OEM?

LLM Wiki

A pattern for building personal knowledge bases using LLMs.

This is an idea file, it is designed to be copy pasted to your own LLM Agent (e.g. OpenAI Codex, Claude Code, OpenCode / Pi, or etc.). Its goal is to communicate the high level idea, but your agent will build out the specifics in collaboration with you.

The core idea

Most people's experience with LLMs and documents looks like RAG: you upload a collection of files, the LLM retrieves relevant chunks at query time, and generates an answer. This works, but the LLM is rediscovering knowledge from scratch on every question. There's no accumulation. Ask a subtle question that requires synthesizing five documents, and the LLM has to find and piece together the relevant fragments every time. Nothing is built up. NotebookLM, ChatGPT file uploads, and most RAG systems work this way.

GitHub Search Syntax for Finding API Keys/Secrets/Tokens

As a security professional, it is important to conduct a thorough reconnaissance. With the increasing use of APIs nowadays, it has become paramount to keep access tokens and other API-related secrets secure in order to prevent leaks. However, despite technological advances, human error remains a factor, and many developers still unknowingly hardcode their API secrets into source code and commit them to public repositories. GitHub, being a widely popular platform for public code repositories, may inadvertently host such leaked secrets. To help identify these vulnerabilities, I have created a comprehensive search list using powerful search syntax that enables the search of thousands of leaked keys and secrets in a single search.

Search Syntax:

(path:*.{File_extension1} OR path:*.{File_extension-N}) AND ({Keyname1} OR {Keyname-N}) AND (({Signature/pattern1} OR {Signature/pattern-N}) AND ({PlatformTag1} OR {PlatformTag-N}))

Examples:

Bluesky's age assurance sucks, here's how to work around it.

Bluesky's age assurance sucks, here's how to work around it.

Bluesky has implemented age verification measures in response to regional laws that restrict access, prompting users to verify their age through Epic Games' Kids Web Services before they can access adult content.

This sucks, but thankfully there are ways to work around it.

Before diving in: I encourage you to read this entire document, including the
