When good pseudorandom numbers go bad(djnavarro.net) A few weeks ago, in the beforetimes when I’d not personally had the soul-crushingly unpleasant experience of being infected with that covid-19 thing,1 some colleagues2 approached me to talk about a reproducibility issue they’d been having with some R code.
Model Organisms Are Not Static(asimov.press) About 70 percent of scientists say they have tried and failed to reproduce an experiment performed by their peers. And animal studies are, perhaps, among the least reproducible of all experiments because, in an effort to reduce the number of animals used in research, scientists often avoid repeating them to confirm positive results.1 When animal studies are replicated, however, they often yield different outcomes.
Binary Distribution Rebuilds(josefsson.org) I rebuilt (the top-50 popcon) Debian and Ubuntu packages, on amd and arm64, and compared the results a couple of months ago. Since then the Reproduce.Debian.net effort has been launched. Unlike my small experiment, that effort is a full-scale rebuild with more architectures. Their goal is to reproduce what is published in the Debian archive.

Is NixOS truly reproducible?(luj.fr) Build reproducibility is often considered as a de facto feature provided by functional package managers like Nix. Although the functional package manager model has important assets in the quest for build reproducibility (like reproducibility of build environments for example1), it is clear among practitioners that Nix does not guarantee that all its builds achieve bitwise reproducibility. In fact, it is not complicated to write a Nix package that builds an artifact non-deterministically:
Zig Reproduced Without Binaries(jakstys.lt) I decided to bootstrap Zig without using binaries that are checked in the repository and answer if the resulting zig1.wasm in the latest Zig release (0.13.0) is the same the one bootstrapped without using those binaries.
