Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

so i just got hit with 160kb DRAM limit on esp
Then your debugging is mostly around writing thing that generates that flat file and then also around whatever functions read and index the flat file. There is a pretty decent sqlite3 library for Arduino on ESP32 at least: https://github.com/siara-cc/esp32_arduino_sqlite3_lib (and actually another one for idf: https://github.com/siara-cc/esp32-idf-sqlite3 )

How to communicate between ESP32 and MySQL using PHP?
there's sqlite for esp32 if the dataset is static and the sqlite file can fit on a SPIFFS partition

Interesting idea, I guess there's a use case for something with a lighter memory footprint than sqlite3 on an embedded platform.

Frustration about either bugs or my own dumbness
So I just received my watchy today and wanted to upload a new watchface. When trying the arduino-method stated in the official docs I run into this error https://github.com/sqfmi/Watchy/issues/166 .

Watchy: The Hackable $50 Smartwatch
Wow, this article doesn't do it justice.
Watchy is an open source hardware device that uses an e-ink display and has an ESP32 module builtin [0].
SQFMI, the creator of watchy, has a twitter account [1] which has some very nice screenshots [2] [3]. Even the CrowdSupply website has better pics of the device [4].
This is one of the few watches I've been sorely tempted to buy.

E-Ink Watch based on the ESP32
It's on sale on Tindie. But I recommend to look at their github repo. Not many updates and one issue says that example code is nothing you would consider as smart watch. https://github.com/sqfmi/Watchy/releases
What are some alternatives?
SQLite3MultipleCiphers - SQLite3 encryption extension with support for multiple ciphers
EthernetENC - Ethernet library for ENC28J60. This is a modern version of the UIPEthernet library. EthernetENC library is compatible with all Arduino architectures with Arduino SPI library with transactions support. Only include EthernetENC.h instead of Ethernet.h
LittleDB - Little Sql like Database for ESP32 boards
DT78-App-Android - Alternative app for the DT78 Smartwatch. Also works with DT92 & DT66. May work with watches that use the WearFit 2.0 app.
SQLite-ICU-MinGW - Building SQLite and SQLiteODBC on Windows with ICU and other extensions using MSVC Build Tools and MSYS2/MinGW
TFT_eSPI - Arduino and PlatformIO IDE compatible TFT library optimised for the Raspberry Pi Pico (RP2040), STM32, ESP8266 and ESP32 that supports different driver chips
