How Astro 7 renders LaTeX to static SVG and code to dual-theme highlighting entirely at build time, so an article full of equations still ships zero client-side JavaScript.Wed, 24 Jun 2026 00:00:00 GMThttps://iamliao.com/blog/reading-texture-through-motion/https://iamliao.com/blog/reading-texture-through-motion/A short research note on why exploratory movement is part of the tactile signal, not a nuisance to be cancelled — and how sliding speed reshapes what a neuromorphic fingertip reports.Tue, 10 Feb 2026 00:00:00 GMThttps://iamliao.com/blog/spiking-neural-networks-from-lif-to-surrogate-gradients/https://iamliao.com/blog/spiking-neural-networks-from-lif-to-surrogate-gradients/How the leaky integrate-and-fire neuron turns current into spikes, why that spike is a wall for backpropagation, and how the surrogate-gradient trick lets us train deep spiking networks with ordinary autodiff.Tue, 18 Nov 2025 00:00:00 GMT
