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.

FoundationDB: A Distributed Key-Value Store
I’ve been using FDB for toy projects for a while. It’s truly rock solid. That being said, I wish there were more layers.
Ideally someone could implement the firestore or dynamodb api on top.

Go bindings to SQLite using Wazero
For the rough plan, it's Cloud Backed SQLite meets FoundationDB.

SQLite-based databases on the Postgres protocol? Yes we can
- Oh, and if you're wondering about backup to S3, they have that too: https://github.com/libsql/bottomless
- Uh, sqld can integrated with this https://github.com/losfair/mvsqlite, so now your SQLite is backed by FoundationDB!?
- Meanwhile Litestream exists https://github.com/benbjohnson/litestream/
- We Built Fly Postgres

Litestream doesn't do SQLite replication anymore (LiteFS does)
Shameless plug of my [mvSQLite](https://github.com/losfair/mvsqlite) project here! It's basically another distributed SQLite, but with support for everything expected from a proper distributed database: synchronous replication, strictly serializable transactions, + scalable reads and writes w/ multiple concurrent writers.

SQLite: QEMU All over Again?
This project looks really exciting!
I'm working on mvsqlite [1], a distributed SQLite based on FoundationDB. When doing the VFS integration I have always wanted to patch SQLite itself, but didn't because of uncertainty around correctness of the patched version...
A few features on my wishlist:
1. Asynchronous I/O. mvsqlite is currently doing its own prefetch prediction that is not very accurate. I assume higher layers in SQLite have more information that can help with better prediction.
2. Custom page allocator. SQLite internally uses a linked list to manage database pages - this causes contention on any two transactions that both allocate or free pages.
3. Random ROWID, without the `max(int64)` row trick. Sequentially increasing ROWIDs is a primary source of contention, and causes significant INSERT slowdown in my benchmark [2].

Show HN: Query SQLite files stored in S3
That DynamoDB VFS looks cool! I agree that the VFS api makes one think about plenty of crazy ideas. Someone is working on a VFS based on Foundation DB[0] that looks very promising. It was recently discussed here[1]

Fortran on WebAssembly
https://github.com/WebAssembly/wabt/blob/main/wasm2c/README.... is a straightforward way to take an untrusted application (compiled already to wasm) and turn it into C that you can embed into your application or compile to a linkable DLL. I believe this approach has been used to sandbox untrusted libraries in production by Mozilla: https://hacks.mozilla.org/2021/12/webassembly-and-back-again...

Understanding Every Byte in a WASM Module
This seems sort of like understanding machine code vs assembly; it's much easier to learn WAT and translate to/from WASM as necessary using the wabt tools [0].
Either way its super cool how simple WebAssembly is, you can really get your hands dirty and understand exactly every detail of how your program runs!

That seems like quite an undertaking. But at that point, It would make sense to cut out WASM entirely like https://datastation.multiprocess.io/blog/2022-05-12-sqlite-i...

WebAssembly: byte-code of the future
The .wat file can be compiled to a .wasm using wat2wasm which is part of the WebAssembly Toolkit CLI tools:
- DeviceScript: TypeScript for Tiny IoT Devices

Is anyone working/creating tools for wasm in C?
it is in C++ https://github.com/WebAssembly/wabt/blob/main/src/tools/wat2wasm.cc

How to hide script file?
I don't think you are building an application that will use Native Client technologies How to extract source code from Native Client .nexe file, migrate to WebAssembly? #1864 so that would be superfluous, and frankly, useless in your case.

Hey Rustaceans! Got a question? Ask here (5/2023)!
I'm trying to get a basic Rust webassembly program, then porting it to C via wasm2c. The example works, but when I use wasm-bindgen and analyze it with wasm2wat, I get an import "env". The issue is that in C (wasm2c) it comes out as struct Z_env_instance_t; and I can't instantiate it (as in Z_env_instance_t env; to pass it's address to Z_wasm_client_bg_instantiate.
