Technical articles, case studies and analyses on IT security, OpenBSD systems and process automation.
I was developing a project in Rust that told me how much memory I was using. I lost 22 GiB of RAM, so I looked into it to better understand how OpenBSD works.
I’ll share two anecdotes about times when I listened to my clients’ requests and read between the lines. I came up with solutions that the client didn’t even realise they needed.
Sanca, my vulnerability scanner written in Rust, was crashing due to a memory error. I identified the cause and fixed the problem.
I used to waste 5 hours a week sending emails manually from Outlook. I’ve automated the process, and it now takes just 2 minutes.
Frustrated by the quality of the results provided by an EASM, I developed Sanca, an open-source vulnerability scanner that provides evidence for everything it claims.
FreeBSD has always installed the system using Distribution Sets, just like other BSDs. It now offers the option to install the system using packages. Let’s see what this changes.
Fail2ban is one of the security measures I use on my servers to block abuse. In this article, I’ll show you what you can do with it.
I’ve fixed a minor bug in xidle. This bug was getting in my way; I could have used an alternative, but I preferred to fix it.
I proposed a change to doas. Although it was rejected by Theo, this experience illustrates the project’s philosophy of simplicity and how to contribute to OpenBSD.
OpenBSD comes with a Web server called httpd. In this article, I’ll show you how to run a website using httpd, PHP and TLS.
