In this work, we investigate the privacy implications for car owners of this design choice by collecting and analyzing TPMS transmissions from a network of low-cost spectrum receivers that we deploy along the road over a period of 10 weeks. Our measurement study comprises data from 12 verified cars, but malicious…

As in many other countries, cards and other types of electronic payments now dominate everyday commerce. To some, this is a loss. Cash represented a certain freedom from intermediation, a comforting simplicity, that you just don't get from Visa. It's funny to consider, then, how cash is in fact quite amenable to automation. Even Benjamin Franklin's face on a piece of paper can feel like a mere proxy for a database transaction. How different…

The primary goal was to install my work laptop, but I also need to install Linux servers (without Kubernetes, so Talos isn’t an option).Initially, I used Packer to generate a virtual machine image, which I would then clone onto the disk of the machine I wanted to configure. It worked very well for server templates, but for a dev machine, it was a bit…

Because I am deeply concerned about users losing their most sacred data.Over the past year or two, I’ve seen many organizations, large and small, implement passkeys (which is great, thank you!) and use the PRF (Pseudo-Random Function) extension to derive keys to protect user data, typically to support end-to-end encryption (including backups). I’ve also seen a number of influential folks and organizations promote the use of PRF for encrypting data.The primary use cases I’ve seen implemented or promoted so…

🚀 Read this trending post from Hacker News 📖 📂 **Category**: ✅ **What You’ll Learn**: There is a lot of energy right now around sandboxing untrusted code. AI agents generating and executing code, multi-tenant platforms running customer scripts, RL training pipelines evaluating model outputs—basically, you have code you did not write, and you need to run it without letting it compromise the host, other tenants, or itself in unexpected ways.The word “isolation” gets used loosely. A Docker container is “isolated.” A microVM is “isolated.” A WebAssembly module is “isolated.” But these are fundamentally different things, with different boundaries, different attack…
