Can You Get Rich Using a Raspberry Pi to Mine Cryptocurrency? (wired.com)
In olden times, people dug holes in the ground to look for gold. They called it mining. But why is gold valuable, anyway? Well, mostly because humans decided it was valuable. Yeah, but why gold? Well, one cool thing about element 79 is that it doesn't interact with the oxygen in the air, so it stays shiny all the time. Also, it's rare enough to be a status symbol.

Build a tiny CA for your homelab with a Raspberry Pi (smallstep.com)
TL;DR In this tutorial, we're going to build a tiny, standalone, online Certificate Authority (CA) that will mint TLS certificates and is secured with a YubiKey. It will be an internal ACME server on our local network (ACME is the same protocol used by Let's Encrypt). The YubiKey will securely store the CA private keys and sign certificates, acting as a cheap alternative to a Hardware Security Module (HSM).

How I built this website on a Raspberry Pi (mirawelner.com)
As of the time of writing this, the Raspberry Pi 5 has recently been released. Some people are buying it excitedly, while others think that its value over previous models doesn't warrant the price increase. In any event, many people will be implementing various projects on their new (or old) Pis.

Raspberry Pi 500 Delivers Great Performance, Convenient Upgrade to the RPi 400 (phoronix.com)
Four years ago already the Raspberry Pi 400 was announced as a Raspberry Pi keyboard computer built around the Raspberry Pi 4, passively-cooled, and all packaged up nicely in a keyboard form factor. Announced earlier this month was the Raspberry Pi 500 as the successor and now built around the Raspberry Pi 5. For $90 USD this keyboard computer is a very versatile and convenient compact Linux PC.

Self-Hosting a VPN with Tailscale on a Raspberry Pi (github.com/johnnyfivepi)
Inspired by my admiration for Tailscale and their innovative, open-source approach to networking, I decided to challenge myself by setting up a VPN on my Raspberry Pi. Along the way, I also wanted to create a walkthrough that anyone could follow, whether they're just starting out or have more experience. The result? A detailed guide to configuring Tailscale on a Raspberry Pi, from flashing the microSD card to setting up an exit node.

Pi modder successfully adds M.2 slot to Pi 500 (jeffgeerling.com)
As I briefly mentioned yesterday, someone mentioned in this blog's comments a successful M.2 socket installation on the empty header on the Pi 500 (something I attempted, rather poorly!). With a few added components, and 3.3V supplied to a pad on the bottom via a bench power supply, the M.2 slot works just fine, allowing the use of NVMe SSDs or other PCIe devices.

Raspberry Pi 500 makes an 8GB Pi 5 into a compact, inexpensive desktop PC (arstechnica.com)
One of the selling points of the Raspberry Pi 5 (released in October 2023) is that it was fast enough and had enough memory to be a credible general-purpose desktop PC, if not an especially fast one. For Pi-as-desktop enthusiasts, the company has a couple of new pre-holiday announcements. The biggest is the Raspberry Pi 500, which fits the components of an 8GB Pi 5 into a small keyboard-shaped case for $90.
