Tracking NixOS option values and dependencies | oddlama's blog
oddlama.org/blog/tracking-options-in-nixosThere are thousands of options in NixOS, but as users, we usually only interact with a select few of them.

Decorative Cryptography
www.dlp.rip/decorative-cryptographyLast year, I came agross a Linux kernel feature called TCG_TPM2_HMAC. It claims to detect or prevent active and passive interposer attackers.
It all sounds really great. We should care about interposer adversaries. It’s great to use the TPM features that were invented to help us with these problems.

Collaborative Text Editing without CRDTs or OT - Matthew Weidner
mattweidner.com/2025/05/21/text-without-crdts.htmlThis blog post describes an alternative, straightforward approach to collaborative text editing, without Conflict-free Replicated Data Types (CRDTs) or Operational Transformation (OT). By making text editing flexible and easy to DIY, I hope that the approach will let you create rich collaborative apps that are challenging to build on top of a black-box CRDT/OT library.

Using Nix to Fuzz Test a PDF Parser (Part One)
mtlynch.io/nix-fuzz-testing-1Fuzz testing is a technique for automatically uncovering bugs in software. The problem is that it’s a pain to set up. Read any fuzz testing tutorial, and the first task is an hour of building tools from source and chasing down dependencies upon dependencies.
I recently found that Nix eliminates a lot of the gruntwork from fuzz testing. I created a Nix configuration that kicks off a fuzz testing workflow with a single command.
