Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Fighting games use delay-based and rollback netcode
I don't think it's unpopular. We need more and better game software, what exists today is unsatisfactory for a plethora of reasons. I'm personally interested in this because I ship Planimeter Game Engine 2D, which comes with client-side prediction standard, and it's the largest pure-Lua game engine on GitHub.[1]

Starting Box2D 3.0
> Another benefit of speculative collision is that I can elminate[sic] the polygon skin/radius on collision shapes. That was necessary to keep shapes separated for the time of impact algorithm. This should no longer be necessary in version 3.0. I never liked this artificial separation of shapes.
Hah! In Planimeter Game Engine 2D, we shrink physics objects by approximating the polygon skin so that we can achieve "pixel approximate" physics.[1]

When \ is not \
From what I've found maintaining https://github.com/Planimeter/game-engine-2d is that you should be explicitly checking for nil, separately from checking for false-evaluating values.
We found that this had the added benefit of semantically checking for something that did not exist, versus some contextual "false" value.
I suspect this is a good practice in other languages as well.

Ask HN: Any solo game developers here?
Maybe consider https://github.com/Planimeter/game-engine-2d? We have multiplayer with client-side prediction out of the box. Example code is included to demonstrate the ease of networking entity fields, and there is an included payload abstraction for creating networked events.
You can set the tick rate for your game based on your needs as well. And prediction is robust, supporting exceptional packet loss and smoothing over latency concerns for player movement.

The Right Way to Compare Floats in Python
I remember having to write something similar for Lua, because there was no math.approximately() function and I was dealing with networking floats and comparing values over the wire to predicted movement in 2D space.

The specs behind the specs – a deep-dive on ASN.1
What’s so great about ASN.1 and it’s encoding rules is that anyone writing type-length-value serialization for networking purposes, for example[1], is basically independently reinventing ASN.1 because it’s so fundamentally optimal.
It truly will make you wonder why Protobufs and others exist.

Let's Kerberos
The Swedes also started their own from-scratch implementation, known as Heimdal (https://github.com/heimdal/heimdal), which has a bunch of nifty things in it including a from-scratch PKIX/x.509 implementation and a from-scratch ASN.1 compiler and library.

Samba 4.9.5 / Windows 11 22H2 Kerberos Incompatibility - Cross posted from r/samba
Samba uses a embedded version of Heimdal and there is an open issue talking about this problem https://github.com/heimdal/heimdal/issues/1011. TLDR: Heimdal suffers from the 2038 date bug and Windows made a change in one of the requests where a datetime field now returns a date that goes beyond 2038.
