Minecraft on Apple Silicon

In this gist, you can find the steps to run Minecraft 1.16.4 natively on Apple Silicon (AS), without needing Rosetta 2 translation of the dependencies (mainly LWJGL and related libraries).

While it's possible to use a launcher like MultiMC to have a prettier way to run the game on AS, it requires installing even more dependencies (like QT) which take time and are difficult to distribute. Therefore, I've put together a command line-based launcher tool using a couple shell & Python scripts.

To get up and running quickly, follow the steps below. Otherwise, for more detail, watch my YouTube video.

Negative Python user experience on Debian/Ubuntu

The user experience of Python on a minimal Debian or Ubuntu installation is bad. Core features like virtual environments, pip bootstrapping, and the ssl module are either missing or do not work like designed and documented. Some Python core developers including me are worried and consider Debian/Ubuntu's packaging harmful for Python's reputation and branding. Users don't get what they expect.

Reproducer

The problems can be easily reproduced with official Debian and Ubuntu containers in Docker or Podman. Debian Stable (Debian 10 Buster) comes with Python 3.7.3. Ubuntu Focal (20.04 LTS) has Python 3.8.5.

Run Debian container

A description of known problems in Satoshi Nakamoto's paper, "Bitcoin: A Peer-to-Peer Electronic Cash System", as well as notes on terminology changes and how Bitcoin's implementation differs from that described in the paper.

Abstract

The longest chain not only serves as proof of the sequence of events witnessed, but proof that it came from the largest pool of CPU power.

Minimum Viable Async with Node 6

With the release of Node 6.0.0, the surface of code that needs transpilation to use ES6 features has been reduced very dramatically.

This is what my current workflow looks like to set up a minimalistic and fast microservice using micro and async + await.

require-from-twitter

Since Twitter doesn't have an edit button, it's a suitable host for JavaScript modules.
