When I joined the blockchain ecosystem as a programmer in 2017, I had no idea of what a blockchain even was. I discovered this ecosystem that I thought was fundamentally about (left-wing) anarchism. Over the years it seems to me that the ideology that I’ve discovered has been progressively forgotten…

In 2013, I discovered the Rust programming language and quickly decided to learn it and make it my main programming language. In 2017, I moved to Berlin and joined Parity as a Rust developer. The task that occupied my first few months was to build rust-libp2p, a peer-to-peer library in…

Linux was first started in 1991, 29-and-a-half years ago. The POSIX standard, which Linux implements, was started in 1988, 33 years ago. Both of these technologies have seen very little evolution in the core of their design over time, despite all the progresses made in software engineering and computer science. …

If you have been following the development of Polkadot, Ethereum 2.0 or Substrate, you may have heard of libp2p. Libp2p is a network framework that allows you to write decentralized peer-to-peer applications. Originally the networking protocol of IPFS, it has since been extracted to become its own first-class project. As…

People who know me in the Rust community usually think that I’m a game developer, since I contribute mostly to game development libraries in Rust. What they probably don’t know is that in real life I’m doing backend web development for a living, while gamedev is only my dream job. …

The Rust programming language guarantees that your program will never have any undefined behavior as long as you use safe code. This works as long as you use the standard library, but when it comes to C APIs this safety guarantee lays on the shoulders of library writers. Anyone who…

hlua is a Rust wrapper for the Lua programming language which aims to provide a safe interface with this language with minimal overhead. I have a spent a lot of time figuring out how to do that, so I have decided to write about some parts of its design. Introduction to the Lua stack Lua…
