I built a portfolio analysis tool entirely through vibe coding — 100% of the code was written by AI. Here’s what I made and what I learned.

Why Every Software Engineer Should Use AI

Wed, 04 Feb 2026 10:00:00 +0100

This post shares my perspectives on why every software engineer should use AI — a cultural shift as significant as any we’ve experienced.

The Double-Edged Sword of Compounding

Fri, 03 Jan 2025 22:08:00 +0100

While many investors understand the power of compound returns, they may not fully grasp that compounding can also result in a significant downside. This post explores this double-edged sword.

Debugging Hidden GPU Processes in PyTorch

Fri, 02 Nov 2018 14:58:10 +0800

When nvidia-smi shows free GPUs but PyTorch throws OOM errors, here’s how to find and kill zombie processes holding GPU memory.

Understanding Fully Convolutional Networks

Sat, 15 Sep 2018 19:29:22 +0800

I will start from the problem of semantic segmentation, introduce how to use CNNs to solve it, and talk about fully convolutional networks, a widely used framework for semantic segmentation, in great details. Moreover, I will analyze the MXNet implementation of FCNs.
