Explanation of GNU epsilon https://www.gnu.org/software/epsilon/epsilon.html
"The ε core language, an imperative first-order language, is called ε₀. It’s inconvenient for humans to use for serious problems, yet simple and potentially very efficient. Using ε₀ I’ve built ε₁, a higher-level language with a Lispy feel, but untyped — not dynamically typed like Lisp: untyped, like Forth and machine language."

Psiram (formerly EsoWatch) provides the essential realism on topics like esotericism, religion, health, and helps you to save money. Psiram presents false prophets, ideologists, quacksalvers, and snake oil salesmen. Psiram sees itself as a skeptical consumer watchdog against hypocritical, useless and ineffective products, therapies and ideologies.

Pocket SDR is an open-source GNSS (Global Navigation Satellite System) receiver based on SDR (software defined radio) technology. It consists of a RF front-end device, some utilities for the device and GNSS-SDR APs (application programs) written in Python and C. It supports almost all signals for GPS, GLONASS, Galileo, QZSS, BeiDou, NavIC and SBAS.
From Tomoji Takasu, the author of rtklib.
https://www.rtklib.com/rtklib_sdr.htm has a nice table describing GNSS signals.
