Figure 1: Happy little storage buckets made of star stuff. I store all of my critical data in ZFS and replicate it offsite nightly with zrepl . The monitoring page of the zrepl docs mock me with: Monitoring endpoints are configured in the global.monitoring section of the config file. […] zrepl can expose Prometheus metrics via HTTP. Without the ability to fire commands after replication completes, this monitoring solu....

Lately, I have been pondering the waste we generate as we live and the ways to reduce it. As I scale down, I fill trash bags with things I can’t use, which bothers me. The items that can be donated and have a second life are strictly excluded from this definition, though. They’re donated to people who need them. The items that are disposed of include cardboard boxes, plastic containers, and items that have leaked or reached the end of the....

New Tool: xstack - Completely Passive eBPF Linux Stack Profiling Without Any Tracepoints

I just added another tool into my 0x.tools toolset: With xstack , you can passively sample both kernel stacks and user stacks (as long as framepointers are present) with a pretty minimalistic tool, with no direct impact to your critical application processes! While xstack itself is just a data extraction tool, you probably want to summarize/profile all those thread states and stack profiles. Here’s an example of piping xstack output ..

No identities, no logins, you know, just IRC chat rooms, anonymous people. You just talk about your interests, and you don’t present yourself, it’s not about look at me, it‘s about look at this interesting thing. And anything goes.

I’m incredibly excited to finally share something I’ve been pouring my heart into at RogoLabs. For those of you who caught my talk at BSidesLV, you got a sneak peek, but today it’s official: CNAScorecard.org is live! For years, the CVE program has been our shared language for identifying vulnerabilities. But lately, we’ve all felt the growing pains. We’re seeing more CVEs with incomplete, vague, or missing data. This isn’t just a small prob....

We have been working with AI models for development a lot lately (yes, just like everyone else). And I’m seesawing between “damn, that’s impressive” and “damn, brainless fool” quite often. I want to share a few scenarios in which we employed AI to write code, how it turned out, and what I think about the future of AI-generated code and its impact on software development in general.

Minimalist home network monitoring with shell scripts and ntfy.sh

Running a home server does not have to mean setting up a full-blown monitoring stack. For my needs, a few shell scripts and push notifications are all it takes to keep things simple, reliable, and easy to maintain. I use ntfy.sh for notifications. It is a simple, open-source tool that lets you send push notifications to your devices via a single HTTP request. It is lightweight, easy to set up, and fits perfectly with my minimalist approach.
