   Wafer Pass▲116

   Hi HN, I’m Emilio. We’re launching the Wafer extension for the popular IDEs (VS Code, Cursor and Antigravity). Wafer exists to make performance engineers more efficient. Most of the work perf engs do is extracting signal and turning it into the next experiment. You spend hours per kernel doing interpretation and bookkeeping: which counters matter, what changed, what hypothesis you’re testing, what to try next. Wafer is building an environment where profiling, compiler analysis, and docs are first-class context in your workflow, so iteration is cheap. long-term, that same structured context…

   Wag, MFA and Enrollment for WireGuard▲149

   Howdy folk, I've been building this project as both a side project and my job for a little while now. The rationale behind it is while wireguard is a fantastic protocol cryptographically it leaves a lot to be desired when it comes to enrollment and end user device security. Obviously instead of using an off the shelf solution like tailscale, I decided to reinvent the wheel which has honestly been quite fun with learning about eBPF, and recently clustering and HA with etcd! The most recent version (in the docker container) contains about 6 months of very new work bringing it all from sqlite3…

   Wachy – A UI for eBPF-based performance debugging▲116

   eBPF is an amazing technology that allows safely running user-supplied functions at pretty much arbitrary probe points in a kernel/user space context. Much has been written about how amazing this feature is for kernel observability. But as someone who writes user space code, what I find even more amazing is the support for tracing arbitrary user space programs, with no code changes and low overhead. However, doing in-depth analysis can get complicated and time-consuming. My goal with wachy was to make this debugging significantly easier/faster to use, by displaying traces in a TUI…
