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.

Understanding SQL vs. NoSQL Databases: A Beginner's Guide
SQL (Structured Query Language) databases are relational databases. They organize data into tables with rows and columns, and they use SQL for querying and managing data. Examples include MySQL, PostgreSQL, and SQLite.

How to choose the right type of database
SQLite: A lightweight, self-contained SQL database, best for standalone applications, embedded systems, or small-scale applications not requiring a client/server DBMS.

NoSQL Postgres: Add MongoDB compatibility to your Supabase projects with FerretDB
FerretDB is an open source document database that adds MongoDB compatibility to other database backends, such as Postgres and SQLite. By using FerretDB, developers can access familiar MongoDB features and tools using the same syntax and commands for many of their use cases.

Ask HN: Where do I find good code to read?
Rust stdlib code is quite high quality although not particularly dense due to large amount of comments. Start from the docs, and click any source link: https://doc.rust-lang.org/std/vec/struct.Vec.html
Sqlite is supposedly high quality C code: https://github.com/smparkes/sqlite
For videos of someone (Casey Muratori) writing video game code and debugging it, Handmade Hero: https://handmadehero.org/
A blog post about how to write code by the same author: https://caseymuratori.com/blog_0015
For how to implement a fairly advanced type system, Typing Haskell in Haskell: https://gist.github.com/chrisdone/0075a16b32bfd4f62b7b
But, honestly, you're probably better off writing code yourself and learning by doing.

Thinking Forth: A Language and Philosophy for Solving Problems [pdf]
Cool. Here are some other resources that I've encountered along the way of learning Forth:
- JonesForth: https://github.com/nornagon/jonesforth/blob/master/jonesfort...
This is legit a text that goes the an x86 Forth implementation. Actually, it's just an implementation with really extensive comments. That said, including whitespace and comments, it's just 2000 lines and the pedagogy is excellent. Highly recommended for anyone who would rather see behind the curtain before picking up a larger text.
- SmithForth: https://dacvs.neocities.org/SF/
So, Smith decided to hand-write a Forth directly in x86-64 opcodes (well, the corresponding ascii hex bytes). It's incredibly slim and enlightening how you can bootstrap a language in just a couple hundred bytes or so.
This project actually inspired me to really learn the x86-64 architecture, so I ended up hand-decompiling the SmithForth binary instead of going through his commented implementation. Hand-decompilation is an absolutely fascinating exercise. You learn all about ELF structure, opcode encodings, and actually start to see the gaps where microarchitectural details shine through. Highly recommended for any hacker that really wants to grok low level details.
- Mecrisp: https://mecrisp.sourceforge.net/
An amazingly fast Forth implementation for MSP430, ARM, RISC-V, MIPS, and some FPGAs. This gave me one really nice understanding of Forth as
A REPL into your hardware!

Problem Running JonesFORTH
I've git-cloned JonesFORTH (https://github.com/nornagon/jonesforth/blob/master/jonesforth.S) and achieved to compile it (i.e. run make w/o an error. When I start the executable, it presents me with an empty line, and when I say BYE, it says PARSE ERROR: bye.

Ask HN: Where do I find good code to read?
Is there any particular language you're looking for? I've found some languages hideous until I understood them and could appreciate their respective graces. Off the top of my head the I can think of a couple.
The first is Jones Forth (https://github.com/nornagon/jonesforth), start with jonesforth.S and move into jonesforth.f. I really enjoyed following along with it and trying my hand at making my own stack based language.
The other is Xv6, a teaching operating system from MIT (https://pdos.csail.mit.edu/6.828/2021/xv6.html), not all the code or implementations are top notch but it shows you non-optimized versions (just because they're simple and more readable) of different concepts used in OS design.
If you're interested in the embedded world, there is a really neat project I've been following that feels a more structured and safe (as in fault-tolerant) while still staying pretty simple (both conceptually and in the code itself): Hubris and Humility (https://hubris.oxide.computer/).

Dusk OS: 32-bit Forth OS. Useful during first stage of civilizational collapse
Very low hardware requirements, so basic industrial control at the level where you'd otherwise use an Arduino or so but on scavenged hardware. Forth is ridiculously simple to get an implementation running.
https://github.com/nornagon/jonesforth/blob/master/jonesfort...
Is a nice starting point. It's obviously not as compact as say 'Brainfuck' but it is far more versatile.

Making my own forth implementation
OP mentioned jonesforth, but linked to a nasm port of it. Which is probably good it’s just that the documentation in the comments with ascii art doesn’t look right on my screen. So here’s a more common repo: https://github.com/nornagon/jonesforth

Struggling with looping constructs, BEGIN WHILE REPEAT
Rip the asm macros for the basic FORTH words out of this and then embed them in a C binary, statically linked with your favourite libs for whatever task. Although I haven't tried this yet, I'm planning on doing it with ncurses for my own Roguelike. From there, if you can convert the function calls and your parameters down to raw numbers, you can send instructions to ncurses or whatever other API you like, directly from a FORTH stack.
- I'm wondering why so few forth microcontoller tutorials are out there?
