I built a tool that detects bad cases of the Log4j vulnerability

In plain words

Log4Shell.tools is a detection tool designed to identify instances of the Log4j vulnerability. It helps security teams and developers scan for and locate problematic configurations of Log4j in their systems. The tool addresses the critical security issue that emerged in December 2021, providing a straightforward way to assess whether systems are affected by this widespread vulnerability.

  Superlog (YC P26) – Observability that installs itself and fixes bugsMay 2026 · superlog.sh · ▲74

  Hey HN, we’re Nico and Arseniy, co-founders of Superlog (https://superlog.sh). We're building a self-installing, self healing observability tool meant not to be opened. It has a wizard that daily sets up proper logging and an agent that investigates errors and opens PRs. Super short demo: https://www.youtube.com/watch?v=xFhU9Mk247M. In our earlier startups, we tried Sentry, Datadog, Grafana, Dash0, and nothing was good enough. Proper telemetry and alerting still requires a ton of manual setup. We struggled with adding good logs, so debugging was tough, especially as…

  Eigendrum - Draw any shape and hear what it sounds like as a drum▲243

  Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…
