The Sane Rendering Manifesto

The goal of this manifesto is to provide an easy to follow and reasonable rules that realtime and video game renderers can follow.

These rules highly prioritize image clarity/stability and pleasant gameplay experience over photorealism and excess graphics fidelity.

Keep in mind that shipping a game has priority over everything else and it is allowed to break the rules of the manifesto when there are no other good options in order to ship the game.

Do not use dynamic resolution.

Request Units, Storage Utilization, Splits....oh my!

The Unofficial Throughput and Capacity Guestimate Guide for Azure Cosmos DB

Introduction

I have had a lot of great questions about how to estimate the throughput and storage capacity for Azure Cosmos DB. To get yourself up and running, the key best practices references are:

Request Units in Azure Cosmos DB: This document describes what request units and various considerations.
Estimate Request Units and Data Storage: This tool helps you calculate the throughput and storage requirements you need.
Azure Cosmos DB Local Emulator: Use the Azure Cosmos DB Emulator for local development and testing

using Ansible command line:

ansible-playbook --connection=local 127.0.0.1 playbook.yml

using inventory:

127.0.0.1 ansible_connection=local

Raspberry Pi Zero OTG Mode

Simple guide for setting up OTG modes on the Raspberry Pi Zero - By Andrew Mulholland (gbaman).

The Raspberry Pi Zero (and model A and A+) support USB On The Go, given the processor is connected directly to the USB port, unlike on the B, B+ or Pi 2 B, which goes via a USB hub.
Because of this, if setup to, the Pi can act as a USB slave instead, providing virtual serial (a terminal), virtual ethernet, virtual mass storage device (pendrive) or even other virtual devices like HID, MIDI, or act as a virtual webcam!
It is important to note that, although the model A and A+ can support being a USB slave, they are missing the ID pin (is tied to ground internally) so are unable to dynamically switch between USB master/slave mode. As such, they default to USB master mode. There is no easy way to change this right now.
It is also important to note, that a USB to UART serial adapter is not needed for any of these guides, as may be documented elsewhere across the int
