sea-goldon Static Exceptions for Flow Control

> TL;DR

> To create high performance exceptions for flow control in the JVM, simply extend the following StaticException class. Then store the Exception instance in a static final field and throw it as needed. They're fast, because the call stack doesn't need to be traversed and since we're creating reusable objects, there's less for the garbage collector to do.

sea-goldon Bichon: A lightweight, high-performance Rust email archiver with WebUI

Sorry, I don't know all the answers. However, I do know this (from the README):

> Core Engine (Storage & Search): Tantivy[1] > Acts as both the primary storage for email content and the full-text search index. This unified approach ensures high performance and eliminates data redundancy.

sea-goldon Bichon: A lightweight, high-performance Rust email archiver with WebUI

Here is a very similar project: https://emailengine.app/

Similar to Bichon, it also has a commercial license[1]:

> EmailEngine is not free open-source software. It is "source available" software, meaning you can view and copy the source code, but you need a paid subscription[2] to run it beyond the free 14-day trial. Each EmailEngine instance comes with this trial, so you can test EmailEngine without any commitment.

EmailEngine is based on ImapFlow[3], a modern and easy-to-use IMAP client library for Node.js that is MIT-licensed.

sea-goldon Bichon: A lightweight, high-performance Rust email archiver with WebUI

Bichon is in fact AGPL: https://github.com/rustmailer/bichon/blob/main/LICENSE

It must not be using any RustMailer code.

RustMailer (a separate project) has a commercial license: https://github.com/rustmailer/rustmailer/blob/main/LICENSE

> RustMailer is source-available. The code is open on GitHub, but requires a valid commercial license key for production use.

License Purchase: https://rustmailer.com/pricing

The mention of BSD/Apache is from here[1] and looks to be a listing of open-source licenses that this project uses.

How does this compare?

sea-goldon MCP Coordinator: proxy for multiple MCP servers, exposing only 3 tools to Claude

> When Claude needs to use an MCP, the Coordinator dynamically loads it, calls the tool, and returns just the result. This dramatically reduces context window consumption while maintaining full access to all MCP capabilities.

sea-goldon AmneziaWG – WireGuard-Go Fork, Avoid WireGuard Deep Packet Inspection Detection

The predecessor of AmneziaWG, WireGuard, has established itself as a fast and reliable VPN protocol thanks to its compact codebase and high efficiency. However, its fixed packet headers and predictable packet sizes create an easily recognizable signature. DPI systems can effortlessly identify these packets and immediately terminate connections—a critical issue in countries with strict internet censorship.

AmneziaWG 1.5 addresses this issue through multi-level obfuscation at the transport layer: it modifies packet headers, randomizes handshake message sizes, and allows traffic to be disguised as popular UDP protocols. At the same time, the fundamental cryptographic core of WireGuard remains unchanged, preserving its performance and security.

sea-goldon Inko 0.19.1 Is Released

> We're pleased to announce the release of Inko 0.19.1. This release includes support for HTTP servers and clients, pattern matching for let expressions, better code generation, many fixes and performance improvements, and more!

> If you're new to Inko: Inko is a programming language for building concurrent software, but without the usual headaches such as data race conditions and non-deterministic garbage collectors. Inko features deterministic automatic memory management, compiles to machine code using LLVM, supports different platforms (Linux, macOS and FreeBSD, and potentially any other Unix based platform), and is easy to get started with.
