Show HN: Termcraft – 2D terminal survival with multiplayer support https://ift.tt/cPnfI8g

Show HN: Termcraft – 2D terminal survival with multiplayer support Earlier this year, I started developing Termcraft, a terminal-based 2D survival game written in Rust. Since its first release more than half a year ago, I've added multiplayer support, so you can now host a game and play with friends (or colleagues during a meeting?); Up to 8 players. I've also substantially improved the visuals, lighting, physics, and overall gameplay. A friend and I ended up spending the entire weekend playing through the game from start to finish. The progression takes you from gathering wood and building a shelter to crafting equipment, exploring caves, finding diamonds, crossing the Nether, and fighting the Ender Dragon. There are villages, farming, collaborative building, PvP, and player chat along the way. It's open source under the AGPL-3.0 license, with downloadable builds for Linux, macOS, and Windows. Gameplay demo video: https://youtu.be/nn37_15dLFM Installation and controls: https://pagel-s.github.io/termcraft/ It's not perfect, but I'd love to hear your feedback and experiences with the game. Contributions are also more than welcome! https://ift.tt/nAy4EJ5 October 27, 2026 at 12:13AM

Show HN: RPI Pico (RP2040) PIO Emulator Package for Go https://ift.tt/QnIGz8e

Show HN: RPI Pico (RP2040) PIO Emulator Package for Go I have been developing a bus communication protocol for a while using the Raspberry Pi Pico (RP2040)'s programmable IO (PIO) hardware (basically- 8 tiny processors that run assembly programs to manipulate GPIO pins) and I needed some way of testing my programs, as the real hardware is undebuggable. Unfortunately, none of the existing emulators I could find supported connecting multiple RP2040s together, and they each had a few different missing bits of functionality, so I decided to make my own! My emulator supports running multiple RP2040s electrically connected together, and emulates the whole of their PIO blocks (all 8 processors each), along with all of the more niche inter-processor interactions and GPIO functionality I could possibly find in the datasheet. I built it as a Go package so that it can be used inside of other programs; I intend on using it myself inside a test suite against my in-development protocol. I've spent quite a long time checking and double-checking most of the logic so it is as complete and accurate as I can make it, but if you spot anything amiss, I'd really appreciate the feedback. Thanks for checking it out! Hope it can be useful to other RP2040 users. https://ift.tt/IweONuM October 26, 2026 at 10:59PM

Show HN: ReVault – new secure archive format https://ift.tt/CJTd6cm

Show HN: ReVault – new secure archive format reVault is a new, secure-by-default archive format called a lockbox, designed to be simple to use. I've been working on reVault for about 2 years. It was originally written in Dart, but with the improvements in AI, I decided to port it to Rust using AI. It's now in beta, so I'm looking for feedback, particularly around the different language bindings. A lockbox is encrypted, signed and compressed by default. Each can be disabled selectively. - Hybrid post-quantum or passphrase encryption, including metadata. - Zstd compression. - Pure Rust libraries wherever possible. We intend to phase out remaining C code as alternatives become available. The project has been scanned using OpenAI's Daybreak cyber security tools. The manual is a work in progress: https://ift.tt/kC6QUl0 reVault supports Linux, macOS and Windows, x64 and arm64, plus Wasm. The core is Rust, with bindings for C/C++, Java, Dart, Python, Ruby, JS/TypeScript, Go, C#, Kotlin, Lua, PHP and Swift. Within a lockbox you can store: - Files, directories, permissions and symlinks. - Variables. - Forms. Variables, forms and the lockbox itself can have descriptions. reVault uses a portable vault (just another lockbox with structured content) to hold your keys, contacts' keys, lockbox aliases and form definitions. It ties into your platform's secure store, so logging into your desktop unlocks your vault. You don't have to enter a passphrase every time you access a lockbox. You can disable this. There are lots of shortcuts. Creating a lockbox stores an alias in your vault, based on its filename or a name you choose: lbx create /some/path/mybox.lbox lbx mybox open --duration 1h lbx mybox var set KEY VALUE Set a default lockbox and you can leave its name out: lbx session default mybox lbx var get KEY You can mirror a directory tree into a lockbox and update it when the directory changes: lbx store.lbox mirrors project create --from ./project --to /projects/project lbx store.lbox mirrors update The API lets you read, write and seek within files without extracting them to the filesystem. Each lockbox has a table of contents, so extracting a single file from a multi-gigabyte lockbox is fast. Recovery Updates are transactional, with automatic rollback for failed updates. The format is designed for recovery: content is stored in pages, allowing unaffected content to be recovered if part of a lockbox is corrupted. Sharing An encrypted lockbox is more useful if you can share it. reVault has an open-source keyserver for exchanging public keys, with validation through a second trusted channel. It's still experimental. OnePub has donated a server to run a single keyserver. If you're interested in donating resources, I'd like to bring up a second redundant server. It's pure Rust, uses under 100 MB RSS and supports rate limits. To publish your default profile's public key: lbx vault profiles email you@example.com lbx vault profiles publish Give the publish code to your contact. They can import your key: lbx vault contacts receive Display your profile's fingerprint and exchange it through a second trusted channel: lbx vault profiles fingerprint Repeat the process in the opposite direction to get their key. Once you have it, grant them access to your default lockbox: lbx access grant alice You can then email the encrypted lockbox to Alice. To install the CLI and get started: cargo install revault_cli lbx vault init lbx completion install Completion installation detects your shell. To diagnose issues: lbx doctor The language bindings are published to their respective package repositories. I'm looking for constructive criticism of the project on its own merits, particularly the APIs and language bindings. I'm not interested in a debate about using AI. October 25, 2026 at 07:31AM
