How can we make the compiler warn devs when they ignore an important return value? I wrote an article about the #[must_use] attribute. No fluff: medium.com/@gunnar.h.karlsso… #rust #rustlang #rustdev

We’re open-sourcing kache. Until now most people knew us for Kunobi. Today we’re adding something new to the mix - a Rust developer tool we built to solve a problem that kept showing up in our own workflows. Rust build caching is usually framed as a speed problem. In practice, it’s also a storage problem. Once a Rust codebase grows, the same dependency tree gets compiled across branches and CI runs. And with git worktrees each branch keeps its own target/ directory, so identical artifacts quietly multiply across your disk. We felt something was missing. Not just another cache that skips compiles, but something closer to a next-generation sccache. A drop-in RUSTC_WRAPPER that deduplicates artifacts across worktrees, behaves properly on macOS, and can extend into CI without changing how teams use Cargo. That problem led us to build kache. In this blog we explain the motivation behind building it, how the cache works, which platforms and workflows it supports, and why we decided to open source it. Blog: kunobi.ninja/blog/open-sourc… If you’re curious how it works or want to try it, check out the repo and explore the project here: github.com/kunobi-ninja/kach… GitHub Action: github.com/kunobi-ninja/kach… #RustLang #RustDev #BuildSystems #CI #OpenSource #DeveloperTools #kache

Let’s Build a Bitcoin Wallet in Rust: Part III Previously, we built the core of a Bitcoin wallet in Rust: generating secure keys, deriving addresses, and checking balances on testnet. This final installment dives into transaction signing, and broadcasting the transaction to the network. Part III is live now, a 7-minute read: medium.com/@gunnar.h.karlsso… If you've been following along or want to catch up, this series demystifies coding a Bitcoin wallet in Rust in coffee-break sized chunks. #rustlang #rustdev #bitcoin

Let’s Build a Bitcoin Wallet in Rust: Part II We're building our own Bitcoin wallet from scratch, in Rust! In Part II, we take the next big step: we connect your new wallet to a Bitcoin testnet node. You wallet will show your testnet BTC balance, funded by a faucet. Part II is a 6-minute read. Find it here: medium.com/@gunnar.h.karlsso… #rust #rustlang #rustdev #bitcoin

Let’s Build a Bitcoin Wallet in Rust: Part I Ever wondered what it really takes to build your own Bitcoin wallet from scratch? Not just calling an API — but understanding the crypto primitives, generating secure keys, deriving addresses, and sending transactions. This new 3-part tutorial series will walk you through creating a minimal, command-line Bitcoin wallet entirely in Rust. By the end of the series, you'll have a working testnet Bitcoin wallet you can use to generate keys and address, check your balance and send testnet BTC. One of the best ways to truly grok Bitcoin self-custody? Build it yourself. Part I of the tutorial series, a 6-minute easy read, here: medium.com/@gunnar.h.karlsso… #rustlang #rustdev

Exploring zero-knowledge proofs in Rust lately—halo2 solana-program crate combo looks promising for private order execution bots. Early experiments show sub-100ms proof gen on devnet. Privacy layer could be huge next cycle. Anyone else tinkering with ZK on Solana? #ZK #RustDev

Negative implementations in Rust are weird: There is Send, and then there is !Send (not Send) There is Unpin, and then there is !Unpin (not Unpin) Why do we need to say that something is not something else? 3-minute read with a short clear example: medium.com/@gunnar.h.karlsso… #rust #rustlang #rustdev

Every dev learning Rust eventually asks: “Wait… what actually is Pinning?” It looks completely pointless until you realize it's the hidden foundation making zero-cost async Rust possible. I've written a simple explanation concrete example. 5-minute read: medium.com/@gunnar.h.karlsso… #rustlang #rustdev

What is the mysteriously named PhantomData in Rust? And why does Rust need a type that only pretends to exist? I wrote a quick 3-minute read with a clear example: medium.com/@gunnar.h.karlsso… #rustlang #rustdev
