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.

Remotely powering on and off a rover through wifi?
In my learning journey I have come to realize that BMSes do exist and my silly setup is both redundant and not very good at keeping the battery safe. I found a smart BMS by a company called JBD that has several 3rd party libraries written for it, including the one I'm using by a fellow redditor here called /u/MrSurly. Here's a link to his BMS library. The BMS library allows me to communicate with the BMS using the RPi, I get information such as the voltage of each cell, current output, and more information. It also automatically stops the discharging when the battery is about to die.

Can't find a BMS with communication for LiPo
You can use the BMS Tools Python library, but I'm biased, as I wrote this.
- I created an open source tool for the JBD / XiaoXiang BMS.

BMS firmware SOC strategies?
So, I went down a rabbit hole of creating an open-source app for the somewhat popular JBD / XiaoXiang BMS. I was messing about with the features provided by the somewhat clunky official Windows app, and tried to do a firmware update on the BMS, and promptly bricked it.

What are you having difficulty learning or are currently struggling to learn?
Thank you! Yeah, I've tried a variety of edits to the function call, it's from the backend of a very professionally done python package with the reverse-engineered protocol for this pretty ubiquitous type of BMS; It is very cleanly written but also broken out into a ton of little stepwise functions many of which I don't understand... Enum types, lots of decorators (@staticmethod, @serial.setter, @property) and dunder enter/exit's... but I get the gist of it, every time I ask it it to read data it opens the port, constructs the bytes for the read command, sends them over the port, then collects the response byte-by-byte, verifies the final checksum byte, if ok then converts the payload to a dict otherwise raises an exception, and finally returns the data dict.

Observable 2.0, a static site generator for data apps
Yep, Evidence is doing good work. We were most directly inspired by VitePress; we spent months rewriting both D3’s docs (https://d3js.org) and Observable Plot’s docs (https://observablehq.com/plot) in VitePress, and absolutely loved the experience. But we wanted a tool focused on data apps, dashboards, reports — observability and business intelligence use cases rather than documentation. Compared to Evidence, I’d say we’re trying to target data app developers more than data analysts; we offer a lot of power and expressiveness, and emphasize custom visualizations and interaction (leaning on Observable Plot or D3), as well as polyglot programming with data loaders written in any language (Python, R, not just SQL).

Animated map showing frequency and location of births around the world [OC]
I made this interactive visualization that attempts to show the real-time frequency and location of births around the world. A country’s annual births (i.e. the country’s population times its birthrate) were distributed across all of the populated locations in each country, weighted by the population distribution (i.e. more populated areas got a greater fraction of the births). Data Sources and Tools Population and birthrate data for 2023 was obtained from Wikipedia (Population and birth rates). Population distribution across the globe was obtained from Socioeconomic Data and Applications Center (sedac) at Columbia University. Data is processed and visualized at a 1 degree x 1 degree resolution, each of which has a different probability of a birth occurring in a specific time period. D3.js was used to create the map elements and html, css and javascript were used to create the user interface.

How do you implement library types?
When I go to the homepage of types/d3 the only hint for any kind of documentation is what seems to be the main github page of d3. It's highly possible I'm missing something here, so sorry if I am but I can't find any documentation of how you are supposed to type these library objects.
