5Gbps Ethernet on the Raspberry Pi Compute Module 4
tl;dr: I successfully got the Intel I340-T4 4x Gigabit NIC working on the Raspberry Pi Compute Module 4, and combining all the interfaces (including the internal Pi interface), I could get up to 3.06 Gbps maximum sustained throughput. Update: I was able to boost things a bit to get 4.15 Gbps! Check out my video here…

Why Apple Will Switch to ARM-Based Macs (2014)
When Steve Jobs announced the transition from PowerPC to Intel processors in 2005, he revealed something that, in hindsight, seemed obvious to everyone who didn’t anticipate the switch: There are two major challenges in this transition. The first one is making Mac OS X sing on Intel processors. Now,

Hand Tracking for Mouse Input (2023)
The other day I saw the launch of Apple Vision Pro, the whole thing was very interesting, but one thing that caught my attention was the finger input. It seems very intuitive, by using the finger pinching as sort of like a cursor or mouse input. I figured I want to try it out, so I took it upon myself to create it.
