Roland asked why the red overlay sits on the DARK basemap rather than
greyscale or black. Measuring it, black is the better answer and the
reason is not brightness:
flavor distinct colours hued earth luminance
dark 19 4 0.014
black 13 0 0.007
Both media filters are the same pure luminance projection --
`0.2126 0.7152 0.0722` -- so they keep brightness and throw hue away.
`black` is already achromatic, so filtering it is a hue rotation and
nothing else: all thirteen greys were authored as a monochrome hierarchy
and every one arrives intact. `dark` has more colours, but four of them
are hued (water, parks, up to 25 chroma) and those distinctions do not
survive at all -- the features land at whatever brightness their hue
happened to carry rather than one anybody chose. Black also emits half
the light on the earth fill, which is the point of a night-vision theme.
`grayscale` is not an option despite the name: it is a LIGHT theme (earth
L0.604), and a luminance filter turns a light map into a bright red one.
What made black look impossible in the first commit was the sprite, and
that was my mistake: `sprite` and the layer flavor are separate style
properties that merely shared one variable. We ship `light` and `dark`
sprite sets, and a `black` basemap with `dark` icons is an ordinary style.
They are now separate arguments, with `mapSprite()` beside `mapFlavor()`.
Fixed in passing: the contour labels branched on `flavor === "dark"` and
would have taken the LIGHT branch for `black` -- dark brown text on a
black map. Now branches on `light`, so every dark flavor gets the pale
label.
The new test is the one worth having: the monochrome themes' flavor must
paint with greys only, paired with an assertion that `dark` is NOT
achromatic. Without that pair the first would pass on any flavor at all
and prove nothing about the choice.
1096 jest / 61 suites, 4 e2e themes, clean build.

WROLPi
Create your own off-grid library.
WROLPi is a self-contained collection of software to help you survive the world Without Rule of Law.
WROLPi is intended to be run on a Raspberry Pi with an optional external drive attached. It serves up it's own Wi-Fi network so that any user with a laptop/tablet/phone can connect and use the library created by the maintainer.

Try WROLPi!
You can try out WROLPi by running the docker containers.
- Install docker-ce and docker-compose
- Copy the latest WROLPi code.
git clone https://github.com/lrnselfreliance/wrolpi.git
- Change directory into the code base.
cd wrolpi
- Initialize git submodules
git submodule update --init
- Build the containers.
docker-compose build --parallel
- Create volumes.
docker volume create --name=openstreetmap-datadocker volume create --name=openstreetmap-rendered-tiles
- Initialize the database (SQLite in the media directory).
docker-compose run --rm api db upgrade
- Start the docker containers.
docker-compose up
- Browse to WROLPi.
More Docker documentation is available in docker/README.md
Install WROLPi
Full installation instructions are in INSTALL.md. Pick the option that matches your hardware:
- WROLPi Portable (Live USB) — boot a complete WROLPi from a USB stick on any x86 PC or laptop. Nothing is installed to the computer; the first boot creates a persistence partition on the USB so your library, database, and configuration survive reboots.
- Debian 12 — install WROLPi onto an x86 PC or laptop.
- Raspberry Pi — install WROLPi onto a Raspberry Pi with an external drive.
- Docker — run the WROLPi containers on an existing Linux host.
Charter
Guiding Principals
- Storage is cheaper than power.
- Two is one, one is none.
- Run silently.
- Primary, secondary, tertiary.
- Secure as a bookshelf in your home.
Physical properties
- A WROLPi instance should be capable of running with a minimal of hardware:
- Raspberry Pi
- SD card
- External USB hard drive
- Power supply and cables
- Wi-Fi USER device such as a phone, tablet, or laptop.
- A WROLPi instance should consume a minimal amount of electricity during WROL event. It is expected power will be scarce when WROLPi is needed most.
User expectations
- A WROLPi instance should be run and maintained by a person (MAINTAINER) with a moderate amount of Linux and Raspberry Pi experience. It is expected that they should be able to do this using only the documentation on their WROLPi.
Software properties and capabilities
- A WROLPi instance should be able to "factory-reset" itself without any outside services.
- WROLPi should function completely without any internet services.
- A user should have easy access to their data if WROLPi fails:
- For example, a user can watch their videos by navigating a short and intuitive directory structure and opening the video in their preferred video player.
- WROLPi should be self-documented. The UI should contain a tutorial for USERS as well as the MAINTAINER.
- If the UI isn't functional, the code should be documented such that a user can restore functionality.
- WROLPi should favor pre-processing, rather than processing during a WROL event. Such as re-encoding a video, or processing captions. This is to ensure that when a user adds content during non-WROL time, the processing for optimum performance is already done for a WROL event.
