• Sergio Durigan Junior: Using WireGuard to host services at home

  It’s been a while since I had this idea to leverage the power of WireGuard to self-host stuff at home. Even though I pay for a proper server somewhere in the world, there are some services that I don’t consider critical to put there, or that I consider too critical to host outside my home.

• Some views on protocols and encryption

  The start of my views is that encrypted NFS with Kerberos is different from IMAPS or encrypted SMTP because both of the latter are instances of ' over TLS', while encrypted NFS with Kerberos is its own bespoke, unique cryptographic protocol and implementation. I like ' over TLS' (provided that TLS identities are competently handled), because TLS is a well studied, reasonably well understood, and usually well implemented thing (if you use a common implementation, and everyone should). Bespoke cryptography is something I consider dangerous because historically it's had a rather bad track record (both in implementations and in protocols). A lot of effort from many people and hard lessons learned have gone into TLS, far more than into a niche bespoke system (which encrypted NFS with Kerberos definitely is).

• OpenZFS For HPC Clusters

  As the age of data growth and sprawl continues to evolve, the demand for high-performance, secure, and scalable data storage solutions has become more critical than ever before. However, despite the rising need, the number of available options for meeting these requirements is dwindling. As a result, businesses and organizations are facing significant challenges in selecting the right solution that fits their specific needs and budget.

  Fortunately, OpenZFS is emerging as a popular and excellent choice for building the storage backbone of any high-performance computing system. OpenZFS is an advanced file system and volume manager that offers robust features such as data compression, deduplication, and checksumming. These capabilities allow organizations to store, manage, and access their data efficiently, securely, and with the highest level of integrity.

• Linux: Difference Between /dev/tty, /dev/tty0, and /dev/console

  Linux / UNIX supports device files that are stored in the /dev directory. These aren’t actual files, rather, they are special files or character devices that are representative of hardware devices attached to the system.

  Some of the most commonly misunderstood device files are /dev/console, /dev/tty, and /dev/tty0. In this guide, we will explore the nuances that distinguish these three device files.
