TrueNAS on a Raspberry Pi 5: A Hacky but Educational Journey

2025-08-28

The author attempts to run TrueNAS, a network storage system typically used on more powerful hardware, on a Raspberry Pi 5. Due to the Raspberry Pi's lack of official UEFI support, a community project, rpi5-uefi, is used. While successfully installing TrueNAS, limitations in UEFI mode—including missing fan, GPIO, and built-in Ethernet support, plus restrictions on multiple PCIe devices—prevent some hardware from being recognized. The author concludes that while a challenging learning experience, higher-end Arm hardware is still recommended for high-performance needs.

M4 Pro Mac mini 4TB SSD Upgrade: Speed vs. Cost

2025-07-12

The author upgraded their studio's M4 Pro Mac mini from a 512GB SSD to a 4TB SSD. The upgrade process was relatively straightforward, but removing the bottom cover required care to avoid damaging the power button connector. A DFU restore was necessary, achievable with Macs containing a T2 chip. Performance tests showed the upgraded 4TB SSD had significantly faster write speeds and comparable read speeds to an external Thunderbolt 5 NVMe drive, but with greater consistency. While expensive ($699), it's significantly cheaper than Apple's $1200 option.

Stop Killing Games: The Future of Game Ownership and Digital Rights

2025-07-05

The author recounts their experience of YouTube taking down a video on self-hosting and buying a new dishwasher only to find its functionality locked behind an app requiring WiFi and a Bosch account. This sparked reflection on digital product ownership, especially in gaming. They point out that more and more games rely on DRM and online connections, resulting in shorter game lifespans and players losing long-term ownership. The article calls attention to the "Stop Killing Games" initiative, hoping to change game design and sales models to protect player rights and restore the meaning of actually "owning" a game.

Mini NAS Showdown: GMKtec G9, Aiffro K100, and Beelink ME mini Compared

2025-07-05

The author downsized their homelab from a 24U rack to a mini-rack, necessitating a smaller NAS. Three mini-NAS options were tested: GMKtec G9, Aiffro K100, and Beelink ME mini. All use Intel N100/N150 chips and support multiple M.2 NVMe SSDs. The G9 offers great value but had initial cooling issues. The K100 is small, cool-running, but pricey and lacks built-in eMMC. The Beelink ME mini is highly expandable and quiet, but some slots have lower bandwidth. The best choice depends on individual needs; the author leans towards the K100, but SSD costs are a factor.

Intel N150 Mini PC vs. Raspberry Pi 5: A Year Later, the Verdict is In

2025-07-04

A year-long comparison of the Intel N150 mini PC (GMKtec NucBox G3 Plus) and the Raspberry Pi 5 16GB reveals a nuanced picture. While the N150 boasts superior raw performance thanks to its faster processor and (in some configurations) DDR5 RAM, it lags behind the Pi 5 in power efficiency. The performance of N100/N150 systems varies greatly depending on the accompanying RAM, IO, and cooling solutions. Used mini PCs offer a significant cost advantage, but new machines require a careful comparison of specs. Ultimately, the best choice depends on individual needs; it's like comparing a bicycle to a car – each has its strengths and weaknesses.

Effortless Weather Station Data Acquisition with a Raspberry Pi

2025-07-01

The author effortlessly acquired data from an Acurite weather station using a Raspberry Pi and Software Defined Radio (SDR). By installing rtl_433, the Raspberry Pi automatically identified and decoded the weather station's 433MHz wireless signal, displaying temperature, humidity, wind speed, wind direction, rainfall, and lightning information. For better data visualization, the author also installed WeeWX software and configured the weewx-sdr plugin, ultimately creating a local weather data web dashboard. The process involved configuring sensor mapping and adding udev rules to grant the WeeWX user access to the SDR device.

Pixelated Video Isn't Secure: A $50 Bounty and the Power of Reverse Engineering

2025-04-15

A YouTuber pixelated a section of a video showing a folder's contents and offered a $50 bounty for anyone who could decipher it. Within a day, three individuals successfully recovered the information using techniques involving TensorFlow and other tools. This experiment demonstrates that simple pixelation is not a secure method for concealing information, especially in moving videos. AI-assisted reverse engineering makes it surprisingly easy to de-pixelate. The YouTuber concludes that solid color masks are a better solution for hiding sensitive data.

NAB Show Reveals 10ns GPS-Synchronized ATSC 3.0 Timing

2025-04-13

At this year's NAB Show, a surprising discovery was made: a precise time synchronization technique using a u-blox GPS receiver and an ATSC 3.0 television signal, achieving a pulse synchronization of ±10 ns between the two. This experimental timing standard, called BPS (Broadcast Precision Synchronization), could be integrated into the US ATSC 3.0 rollout. Its significance lies in providing a reliable terrestrial backup to GPS, enhancing resistance to various jamming attempts, which is crucial for media, power grids, 5G communications, and more. Furthermore, the show also featured consumer-grade Intel motherboards with built-in PPS input/output connectors, highlighting the growing adoption of precise time synchronization technology.

My Bosch Dishwasher Demands a Cloud Connection: A Lament

2025-03-24

The author bought a Bosch 500 series dishwasher, praising its easy installation. However, key features like delayed start and eco mode require a Home Connect app and Wi-Fi connection. This sparked a reflection on manufacturers' over-reliance on cloud control, potentially contributing to planned obsolescence and data harvesting. The author argues that appliances should prioritize local control, with cloud features as add-ons, not replacements for core functionality. This creates unnecessary obstacles and dependence on internet access for basic operations.

Radxa Orion O6: Ambitious Open-Source Arm V9 Motherboard, But Needs Refinement

2025-02-04

Radxa's Orion O6 motherboard boasts being the world's first open-source Arm V9 motherboard, promising high performance, low power consumption, and enhanced security. However, real-world testing reveals performance doesn't quite match the marketing hype of rivalling Apple's M1 chip. While outperforming some competitors in certain benchmarks, results are mixed elsewhere. Furthermore, the open-source hardware claim is questionable, with full schematics and OSHWA certification currently absent. Software-wise, the pre-installed OS presents issues like a default device tree configuration and unusual CPU core load distribution. In short, the hardware shows promise, but software and driver support require significant improvement. Proceed with caution and temper expectations.
