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.

Why Python's Integer Division Floors (2010)
This is because 0.1 is in actuality the floating point value value 0.1000000000000000055511151231257827021181583404541015625, and thus 1 divided by it is ever so slightly smaller than 10. Nevertheless, fpround(1 / fpround(1 / 10)) = 10 exactly.
I found out about this recently because in Polars I defined a // b for floats to be (a / b).floor(), which does return 10 for this computation. Since Python's correctly-rounded division is rather expensive, I chose to stick to this (more context: https://github.com/pola-rs/polars/issues/14596#issuecomment-...).

Stuff I Learned during Hanukkah of Data 2023
That turned out to be related to pola-rs/polars#11912, and this linked comment provided a deceptively simple solution - use PARSE_DECLTYPES when creating the connection:
- Polars 0.20 Released
- Segunda linguagem
- Polars: Dataframes powered by a multithreaded query engine, written in Rust
- Summing columns in remote Parquet files using DuckDB
- Polars 0.34 is released. (A query engine focussing on DataFrame front ends)

I created a simple CLI tool that helps you code FAST!
I've always wanted to build a CLI tool, and when I realized that you can build one using React with Ink, I converted my Python script into a CLI tool.

Delete git branches in batches
⚠️ Git for Windows Terminal is currently not supported, and the tool is limited to ink. We will look for alternatives later. Please use CMD, Vscode terminal's Git... terminal

Setup Simple Web UI for Node.js App in Seconds
There is a good solution for some of those cases - ink. With ink, I can implement text-based UI with knowledge of React, which is neat but there are still some caveats for my usages:
-
Building Reactive CLIs with Ink - React CLI library
Looks cool, right? Building a similar UI in the terminal without any library would be quite hard, though, thanks to Ink it's almost as easy as building any frontend UI with React.

Terminal-like output library for js?

Synchronous File Reading and Writing in Node.js
I'm writing a CLI with ink. Writing async code is important as to not block the rendering and respond to user input. I have a few loading animations that update every 100ms. Synchronous operations can make the animation hang for >500ms, making the animation choppy.

Launch HN: Resend (YC W23) – Email API for Developers Using React
You get the comfort of using react components instead of fighting with HTML tables to make your emails look nice. I think it's awesome! It's analog to what ink[0] does with CLI outputs. Sure, you could write fancy CLI outputs in bash, but ink takes the pain out of it and makes it easy.

Is Node.js a good way to implement a CLI app with persistence?
Due to Node's asynchronous behavior, it makes Node great for long-running processes that make a lot of HTTP requests, database calls, and other async ops, like a web server or a REST API. However, if I am making a CLI tool for pretty much personal use only, with very minimal async operations, then blocking the event loop with a synchronous function that will resolve almost immediately will make no difference perceivable to a human brain or have any speed benefits that someone can actually observe (think `fs.readFileSync` or `require('dotenv') of 10 line config file, or a quick embedded db (sqlite) query with only ~100 records. I'm wondering what the best way to implement the database part of the app synchronous. I can read/write to JSON files but it would be tricky because the data is relational, and some complex joins and other data wrangling operations are required (complex to perform in JS but are easy to implement in a SQL statement). It's not important what the operations are, that's not the point of this post. This is mostly a personal project of interest: making this CLI tool completely avoiding any async operations/using no promises. I would like to use node tho, as I said this is just out of interest and I also want to experiment with several CLI libraries such as Ink or Cliffy.
