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.

Julia fractal, with a table to do integer multiply! (2.a.b = (a+b)^2 - a^2 - b^2, so just precompute all x^2 in a table! )

Another World Ported to FPGA
For anyone confused by the HDL, it's the authors custom language: https://github.com/sylefeb/Silice/tree/master
It provides a compiler to Verilog that then can be fed to traditional design flows.

Have a look at Silice, it's brilliant.

How to contribute to open source?
I'm an intern at a french IT lab and my boss is working on an open-source FPGA language, you might want to check it out https://github.com/sylefeb/Silice .

Calyx: Intermediate Language for Hardware Accelerators
My first instinct was to ask "Does this play well with CIRCT?" And thankfully they answer that right away in the README.
I'm personally of the opinion that there is a LOT of room for improvement in the hardware design tooling space, but a combination of market consolidation, huge pressure to meet deadlines, and an existing functional pipeline of Verilog/VHDL talent is preventing changes.
That's not to say "Verilog/VHDL are bad", because clearly they've been good enough to support nearly all of the wonderful designs powering today's devices. But it is to say, "the startup scene for hardware will continue to look anemic compared to the SaaS scene until someone gives me all of the niceties I have for building SaaS tools in software."
A huge amount of ideas (and entire designs) start off as software sims, which enables kernel/compiler engineers to start building out support for new hardware before it's manufactured.
There is some interesting work going on at SiFive building hardware with Chisel[1], as well as some interesting work lead by a professor at William and Mary to improve simulations[2].

I may be creating an abomination
Inspired by Scala. Which can do a whole lot more, and worse. The currently biggest competitor to decades old hardware description languages is a Scala DSL.

Trying to learn and work with FPGAs
I'm also a hobbyist. There are a number of alternative HDLs out there, and as hobbyists we can deviate more from the mainstream of (System)Verilog and VHDL if we desire, though you'll still need to be able to read them. In the past I've done Verilog, but lately I've been using SpinalHDL and have been really enjoying it. Its close relative Chisel also makes appearances in the RISC-V space.
- Alternate HDL language and Physical Design/EDA tools?

Learning VDHL after knowing Verilog
What are your thoughts on other HDLs like Chisel or BlueSpec when it comes to better type checking?

Learning Verilog and FPGA
I started playing with FPGAs and HDLs a couple years ago with no hardware design background (I'm mostly a software architect/engineer) and in the end found that a "higher-level" HDL suited me better.
I chose Chisel (https://www.chisel-lang.org/) an HDL based on Scala (technically a Scala DSL) which can provide many facilities to hardware generation.
I'd highly advise looking into it although also knowing Verilog helps a lot.

If you keep clicking "Give 15 seconds" on Lichess, eventually it overflows to a negative number and you win
But some go further and ask "what if when we add a soldering station on top of it?"
