How to: Allow Node to bind to port 80 without sudo

TL;DR

Only do this if you understand the consequences: all node programs will be able to bind on ports < 1024

sudo setcap 'cap_net_bind_service=+ep' /usr/local/bin/node

Important: your node location may vary. Use which node to find it, or use it directly in the command:

# delete local tag '12345'
git tag -d 12345
# delete remote tag '12345' (eg, GitHub version too)
git push origin :refs/tags/12345
# alternative approach
git push --delete origin tagName
git tag -d tagName

TPM2 Protocol Implementation

Introduction

Frame data is transferred inside packets (similar to DMX, for example). A frame is an image representing a matrix or a light scene.

The packets start and end with one-byte characters. In between are a few control bytes followed by the payload. There is no set size for a payload; it is transmitted with each packet. This makes the protocol quite flexible. There are enough bytes in a single packet for an RGB matrix with 21,845 pixels, but if you just want to control an RGBW lamp, that only requires 9 bytes. The variable frame size means there is no overhead, allowing for maximum transfer speed.

This "trend chart" shows loading times across releases of a hypothetical web application.

It is a mixture of a line chart and an area chart, with the daily median loading time indicated by the line and percentile ranges indicated by the surrounding areas.

The "lollipops" mark releases of (different parts of) the application.
