space-nerds-in-space VS linux

I don't know if this counts, but I wrote a parser for "the ship's computer" in my game, "Space Nerds in Space". It's described here: https://scaryreasoner.wordpress.com/2016/05/14/speech-recogn...

I also wrote some toy "interactive fiction" things (with less sophisticated parsers) in python and Lua as a way to gain familiarity with those languages, not that they are very interesting in and of themselves, though they demonstrate a fairly standard technique behind these kinds of games in a compact way.

I have this book, which I got about 10 years ago, and found it very helpful when writing my own (primitive, not even close to state of the art) game in C, and I have recommended this book to others on reddit many times over the years. My copy of the book still has the CD inside, never opened. I never looked at it, mainly because I found there's no need, the algorithms are not very long for the most part, and I needed to understand them and fit them into my codebase anyway.

Space Nerds in Space - multi-player starship bridge simulator so you can captain your starship through adventures with your friends.

Space Nerds in Space (github) is an open source spaceship bridge simulator so you can captain your starship through space adventures with your friends. Each player mans a station on a simulated starship. There are stations for Navigation, Weapons, Engineering/Damage Control, Comms, Science, and a gamemaster station. It's written in C, with a Lua API for writing "mission scripts". Multiple starships can be present in the simulation at once if you can manage to gather enough friends to crew them. It even supports speech recognition and natural language parsing if you're so inclined.

This is what gaseous-giganticus uses. Combined with some other techniques, it can help with making some clouds for earthlike planets, but not in real time. Mentioned here previously. The process I use for making earthlike planets with clouds for Space Nerds in Space is described here.

As an example, I made this game which is basically a multiplayer star trek game where each player is a member of the crew of a spaceship. There are "scenarios" -- little missions -- that are coded in Lua, some written by me, some by other people. You can see them here: https://github.com/smcameron/space-nerds-in-space/tree/master/share/snis/luascripts/MISSIONS There's a Lua API my game provides described here: https://github.com/smcameron/space-nerds-in-space/blob/master/doc/lua-api.txt

Not an MMORPG, just a LAN game really, but my spaceship bridge simulator Space Nerds in Space is open source (GPL2) and in C. The network server architecture is pretty simple, TCP, and a read thread and a write thread per client, which would be a bad design if there were a large number clients, but for less than 30 or so clients (realistic number of clients is 5-10, leaning towards 5), it's absolutely fine (KISS principle). There's some documentation about how it all works here: Hacking on Space Nerds in Space and the website for the game is here: https://spacenerdsinspace.com

I have an open source game project I've been working on since 2012 or so. I have received patches from 23 people during that time. Maybe 4 or 5 have made significant contributions (more than drive-by bug fixes, and I'm counting myself in those numbers). Well, you can take a look for yourself and see how the contribution graphs look

These are a bit easier to see what's going on:

Unfortunately Github doesn't have a way to render symbols for whitespace, but you can tell by selecting the spaces that the previous version had leading tabs. Linus changed it so that the tokens `default` and the number e.g. `12` are also separated by a tab. This is tricky, because the token "default" is seven characters, it will always give this added tab a width of 1 char which makes it always layout the same as if it were a space no matter if you use tab widths of 1, 2, 4, or 8.

There was also a Gentoo effort to run atop FreeBSD[0]. The challenge of course is that afaik none of the BSD kernel ABIs are considered stable. The stable interface is the BSD libc. That said, with binfmt_misc, I don't see a reason you couldn't just run (at least some) FreeBSD binaries on Linux with a thin syscall translation layer (rather something like qemu-system) and then your layer hooked via binfmt_misc. I'm not aware of anyone who has done this for FreeBSD, but prior efforts existed as alternate binfmts for SysVr4/5 ELF binaries[2]. Either way would take some elbow grease, but you *might* even be able just reuse binfmt_elf and just have a new interpreter for FreeBSD elf.

> The original less-than check was deemed incorrect

It was only deemed incorrect because of an information leak. Not because it's a valid use-case for user space to copy smaller portions of *hwrpb into user space. https://github.com/torvalds/linux/commit/21c5977a836e399fc71...

Correct. And the combined work needs to carry the MIT license text and copyright attributions for the MIT software authors. With binary distribution it must also be overt, not hidden in some source code drop, but directly accompanying the binary.

Many people who talk about relicensing never credit the MIT developers or distribute the MIT license text. "Because it's GPL now."

I don't think that you believe that, but many developers do.

Some don't see the need for source code scans for Open Source compliance, because the license.txt says GPL, so it's GPL. Prime example is the Linux kernel. There is code under different licenses in there, but people don't even read https://github.com/torvalds/linux/blob/master/COPYING till the end ("In addition, other licenses may also apply.") and conclude it's simply GPL 2 and nothing else.

Also be aware that sublicensing is not the same as relicensing.

He notoriously hates GNU Emacs, yes.

So If we would only count code and not comments, it is only 9489 LoC Rust. Which would be about 0.03% and if we take all lines and not only LoC it would be around 0.05%

AIUI fsync is built on futex_waitv which has been upstreamed. So this has to be more than that.
