Hi. I'm Luke. Email - GitHub - About Me - Twitter - Keybase I'm a co-founder at Nebulous, writing software to re-decentralize the Internet. I studied Computer & Systems Engineering at RPI for 3 years before my long-time friend David and I were bitten by the startup bug. I've previously worked in a cube at Akamai and Kronos, but I don't think I'm going back to that way of life anytime soon. Aside from programming, I like ambient music, 4chan, and eggnog. My main focus right now is Sia, a distributed cloud storage platform. I mostly work on the backend, siad, but have contributed to the frontend, Sia-UI, as well. I also wrote an app for the Ledger Nano S hardware wallet, and currently I'm exploring new ways to interact with the Sia network in a personal project called us. So far, this project has produced: - user: A CLI renter app - shard: A host announcement relay service - walrus: A watch-only wallet server I have also written a series of blog posts about this work: - How to Use Sia Irresponsibly - How to Use Sia Responsibly - Files as Capabilities in us - Talking to Sia Hosts from...Ruby?? - A Lightweight Wallet for Sia I primarily program in Go, which I have used to write a number of libraries and tools. Here are some that I'm especially proud of: - jsteg: A tool for hiding data in JPEGs - frand: A fast-key-erasure CSPRNG in userspace - flagg: Barebones subcommand handling - uint128: A high-performance uint128 package - adiantum: An implementation of the Adiantum cipher construction - randmap: Efficient random map access and iteration (blog post) - ply: A compile-to-Go language supporting generic container operations - geiger: Play a clicking noise whenever you allocate - intersort: Sort anything - freeze: Make any Go object immutable via mprotect Here are my solutions to the Advent of Code. Lastly, some miscellaneous blog posts: - Hacking a ProgComp with Side Channels - How to Access a Running Binary on Linux - What is a Monad?
