Guru's Tech Bytes — April 13, 2026

Good morning. This is Guru's Tech Bytes, Ep. 010, for Monday, April 13th, 2026. First up, a rather elegant bit of mathematics has caught Hacker News's eye. Researchers have shown that all elementary functions — your sines, cosines, exponentials, the lot — can be derived from a single binary operator. It's the kind of paper that makes you wonder whether maths has been overthinking things for centuries. Nearly five hundred upvotes and still climbing. Second, AMD's ROCm continues its quiet march against NVIDIA's CUDA dominance. EE Times reports on the one step after another strategy to break CUDA's grip on GPU software. With AI compute demand still surging, any credible alternative to that lock-in is worth watching closely — and a hundred and forty-seven comments suggest the community agrees. And finally, a sharp essay on why most engineering organisations are flying blind when it comes to team economics. The piece argues that software teams almost never measure what actually matters, and the result is a lot of expensive guesswork dressed up in sprint velocity charts. If you've ever suspected your metrics mean nothing, this one's for you. That's your daily byte. Have a great day. Until next time.
