Atmospherics

1. Preamble

Figure 1.1: My avatar on github, the /tg/station forums, and BYOND

Hi friends! My name is Dunc. As some background, I have been contributing to /tg/ atmos in various ways since 2015. I was tutored by Aranclanos and eventually followed in his footsteps in writing several major refactors of the atmos system. I am a maintainer for the /tg/ codebase and any atmos issues or PRs are my concern. Most importantly, however, is the fact that as of the time of writing I am the only person who understands each component of the current atmos system. That fact is by far the most important reason for the existence of this document; it is my responsibility to share what I know.

Atmospherics is a very complicated and intimidating system of SS13, and as such very few contributors have ever made changes to it. Even fewer is the number of contributors who have made changes to the more fundamental aspects of atmos, such as Environmental Atmos or

1. Use ubuntu (or debian works too for this guide) because i dont know the other distros lmao

2. Run sudo dpkg --add-architecture i386 to enable 32 bits package lists

3. Run sudo apt update to make sure package lists are updated

4. Run sudo apt install libstdc++6:i386 to get the dependencies for BYOND

5. Find the download link for BYOND's linux version from http://www.byond.com/download/, looks like http://www.byond.com/download/build/513/513.1536_byond_linux.zip

Where's The Luv?

An Examination of the CIELAB and CIELUV colorspaces.

It is exciting to see so many new color features for the CSS Color Module. There are nevertheless a couple items that resulted in a "raised eyebrow response". This Gist is mainly going to focus on one: the use of the LAB version of LCh instead of LUV LCh, which may be better suited for the task but appears to have been dismissed as if irrellevant.

I DISAGREE. Luv is in common use and very relevant, and LuvLCh or one of the several LuvLCh variants has distinct advantages over LabLCh for use cases such as choosing color for web content for displays.

Linux Desktop Issues

This is basically my manifesto of why Linux sucks and I keep using Windows as a desktop OS. This is both as a developer platform and end-user targeting.

Look: I would love to be able to use Linux as a daily driver. KDE is amazing and they clearly put far more effort into the desktop experience/UI than Windows (just the volume mixer alone). There are simply far too many underlying and infrastructural problems to the Linux desktop that none of KDE's great UI changes can make up for. I want Linux fanboys, developers, etc... to stop sticking their damn head in the sand about these issues and admit that Linux is still decades behind in some basic infrastructure. This shit can't get fixed if people refuse to admit it's broken in the first place, which some people are far too happy to do.

Desktop App Experience & Developer Tools

Windows has far better desktop apps than Linux, and thanks to WSL, I have all the CLI apps of Linux too. While I do believe KDE Plasma is a much better desk

mmozeiko

This downloads standalone MSVC compiler, linker & other tools, also headers/libraries from Windows SDK into portable folder, without installing Visual Studio. Has bare minimum components - no UWP/Store/WindowsRT stuff, just files & tools for native desktop app development.

Run py.exe portable-msvc.py and it will download output into msvc folder. By default it will download latest available MSVC & Windows SDK - currently v14.40.33807 and v10.0.26100.0.

You can list available versions with py.exe portable-msvc.py --show-versions and then pass versions you want with --msvc-version and --sdk-version arguments.

To use cl.exe/link.exe first run setup_TARGET.bat - after that PATH/INCLUDE/LIB env variables will be updated to use all the tools as usual. You can also use clang-cl.exe with these includes & libraries.

To use clang-cl.exe without running setup.bat, pass extra /winsysroot msvc argument (msvc is folder name where output is stored).

brintness is an integer brightness/lightness/darkness calculation

This is part of an experiment in estimating a perceived brightness while remaining in integer math and using bitshifts to maximize performance.

The Issue

The traditional means to determine the perceived lightness or brightness for a given color value is to first normalize R, G, and B from 0-255 to 0.0-1.0, linearize the values via exponent or more exotic methods (we assume colors are in a gamma encoded color space, such as sRGB), and then after linearizing, creating a linear luminance value by applying coefficients to each of the R, G, B values, adding them, and then finally applying an exponent or more exotic math to find a predicted lightness value.

This is computationally expensive. And even then, we generally miss factors such as the HK effect, and the above as described does not consider the importance of context. In other words, we may say "this is the accurate way" and yet it still lacks in accuracy.
