M4 Mac mini's efficiency
I had to pause some of my work getting a current-gen AMD graphics card running on the Pi 5 and testing a 192-core AmpereOne server to quickly post on the M4's efficiency. I expected M4 to be better than M1/M2 (I haven't personally tested M3), and I hoped it would at least match the previous total-system-power…

Using an 8K TV as a Monitor
TLDR: If your job is to write code all day or stare at Excel spreadsheets, buy an 8K TV instead of a multi-monitor setup. You can even use the same TV for 4K 120 Hz gaming or watching movies as a bonus!

The capacitor that Apple soldered incorrectly at the factory
There have been some past rumblings on the internet about a capacitor being installed backwards in Apple’s Macintosh LC III . The LC III was a “pizza box” Mac model produced from early 1993 to early 1994, mainly targeted at the education market. It also manifested as various consumer Performa models: the 450, 460…

Considerations for a long-running Raspberry Pi
Keeping a Raspberry Pi online and working with zero intervention for weeks, months, or years is somewhat of an art form. Several classes of things can go wrong, and you need to consider how your Pi will recover from each of them.

The Raspberry Pi 5 Is No Match for a Tini-Mini-Micro PC
I've always been fond of the idea of the Raspberry Pi. An energy efficient, small, cheap but capable computer. An ideal home server. Until the Pi 4, the Pi was not that capable, and only with the relatively recent Pi 5 (fall 2023) do I feel the Pi is OK performance wise, although still hampered by SD card performance…
