The dashboard threw on arrival from any other page:
ReferenceError: Cannot access 'useCalculators' before initialization
at Module.useCalculators
at DashboardCalculators
`Calculators.js` exports `useCalculators` as a `const` and imports the ten
calculators it renders. Five of those reached back up to `Apps.js` for
`ColoredInput`, and `Apps.js` imports `CalculatorsPage` from
`Calculators.js` -- so the hub was in a cycle with its own leaves:
Calculators.js -> calculators/ElectricalCalculators.js
-> Apps.js -> Calculators.js
Webpack compiles a `const` export to a live getter, and a getter read
before the module body reaches the declaration THROWS rather than
returning undefined. That is the whole mechanism behind this particular
error, and it names the const it could not reach.
`ColoredInput` is a text field with a Label welded to one edge -- the
calculators' unit markers. It has no business in the module that ROUTES
to the calculators, so it moved to `components/ui/Inputs.tsx`. Nothing in
`components/ui` imports from `components/`, so a control kept there cannot
close a loop like this again. Gallery entry added, per the standing rule.
`src/import-cycles.test.js` is the guard: a small import-graph walker,
scoped to hubs that export a `const` into their own subtree. It fails
with the cycle printed, and it self-checks against a known cycle so it
cannot pass by finding nothing. Verified red with the cycle planted back.
HONEST LIMIT: the guard is static because I could not reproduce the
RUNTIME error in a test. TDZ needs a module to be mid-evaluation when the
getter is read, and by the time any spec body runs every module has
finished; babel also papers over it, handing back undefined where webpack
throws. I tried an e2e that navigates to the dashboard and collects
window errors -- it passes with the cycle present, so it would have been a
test that cannot fail for the reason it claims, and I deleted it rather
than ship it. A react-refresh trigger did not reproduce it either. What
is checkable, and what is genuinely the defect, is the cycle.
1080 jest / 60 suites, 158 in ui-layout.cy.js, 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.
