Beast Mode

Beast Mode is a custom chat mode for VS Code agent that adds an opinionated workflow to the agent, including use of a todo list, extensive internet research capabilities, planning, tool usage instructions and more. Designed to be used with 4.1, although it will work with any model.

Below you will find the Beast Mode prompt in various versions - starting with the most recent - 3.1

Installation Instructions

Go to the "agent" dropdown in VS Code chat sidebar and select "Configure Modes".
Select "Create new custom chat mode file"

BRINTNESS

Fast integer lightness calculations from RGB — by Andrew Somers

brintness is an integer brightness/lightness/darkness calculation

This is part of an experiment in estimating a perceived brightness while remaining in integer math and using bitshifts to maximize performance (avoiding all subtraction, division, and square-root calculations).

The Issue

The traditional means to determine the perceived lightness or brightness for a given color value is to first normalize R, G, and B from 0-255 to 0.0-1.0, linearize the values via exponent or more exotic methods (we assume colors are in a gamma encoded color space, such as sRGB), and then after linearizing, creating a linear luminance value by applying coefficients to each of the R, G, B values, adding them, and then finally applying an exponent or more exotic math to find a predicted lightness value.

Post-modern Linux packaging: additional reading

Summary

This document compiles 2018 coverage around post-modern packaging technologies for Linux, including packaging formats like Snaps and Flatpaks, systems like Nix and Guix and full distros such as Atomic or Clear Linux.

This curation and commentary are current as of 18 June 2018. The curation was prepared by José Miguel Parrella (@bureado) as part of his session at Open Source Summit Japan: Package Management and Distribution in a Cloud World.

We compile these resources in an effort to provide individual developers and organizations with current coverage on the state-of-the-art and motivations of the current post-modern packaging landscape with the intention to increase readiness in experimenting with, evaluating and potentially adopting said technologies.

Disabling GNOME Tracker and Other Info

GNOME's tracker is a CPU and privacy hog. There's a pretty good case as to why it's neither useful nor necessary here: http://lduros.net/posts/tracker-sucks-thanks-tracker/

After discovering it chowing 2 cores, I decided to go about disabling it.
