2022-04-18ripple/fossil: use blake3::CHUNK_LEN as chunk sizeV
This will pave the way for BLAKE3 verified streaming, so we won't have to read objects into memory in their entirety. Change-Id: Ic68dee2ad81448db4969b8c423f0876f0e0272e0
2022-04-15ripple/fossil/mount: drop bmapedef

2022-04-15ripple/fossil/mount: rm rmdir stubedef

2022-04-11ripple/fossil: don't .ok().expect()edef
Result::expect already does the right thing, and discards less information. Change-Id: I2d2fbd1981d4c3b84bb287fb4d79d985f8e465c9

2022-02-16ripple/nix: update sources.jsonV
It's been a while since we've done this, and there are some great new changes in the Rust compiler and standard library. As a bonus, rustfmt now features the `imports_granularity = "One"` variant, so we can use unmodified tooling again. Change-Id: I228e4e5919f53b6a77e07a5c99420936c89016c3

2021-12-27ripple/minitrace: enforce permitted syscall numbersedef
This doesn't discriminate between muxed syscalls yet, but at least bounds the available syscalls to the ones `cc1 hello.c` invokes. Change-Id: I1965f27746b509b32d5e86510e803038765c11dd

2021-12-23ripple/website/nix: fix deploymentV
Our post-update deployment hook expects a callPackage-able default.nix in the root of the repository. Let's fix that! I'm moving the nixpkgs wrapper to another file, so it's still easy to build. Placeholder page until we've actually got content. Change-Id: I5e3ecabe0025c2361e15e31b3c520be6410281ce

Bog standard C hello world. The license info, insofar relevant, is kept separately because it's an unnecessary contaminant. Change-Id: Icf48e11fa44618a7f265f8b083e8a02dc6387711
