What Actually Happens When You Train an LLM? Following the First 12 Hours of the Original Transformer
Hello, I'm Shrijith Venkatramana. I'm building git-lrc, an AI code reviewer that runs on every commit. Star Us to help devs discover the project. Do give it a try and share your feedback for improving the product. In 2017, eight NVIDIA P100 GPUs sat in a Google data center for about twelve hours. During those twelve hours, they repeatedly did something almost embarrassingly simple. They picked up a batch of sentences. Made predictions. Measured how wrong those predictions were. Adjusted a few mi

I Built a Portfolio That Updates Itself When I Push to GitHub
Every developer portfolio has the same problem: you build it once, get excited, and then it slowly goes stale. You ship five new projects over the next year and your portfolio still shows the same three repos from launch day. So I built one that fixes itself. Push a new repo to GitHub, and it shows up on my portfolio automatically — with an AI-written description, not just the raw GitHub blurb. Connect LinkedIn, and my experience and education populate themselves too. This is the full breakdown

Rebuilding the Windows 98 Defrag Simulator
There's a specific kind of satisfaction that comes from watching the Windows 98 defrag screen do its thing. Clusters shuffling around. That progress bar crawling. The sense that your computer was doing something important, even if you had no idea what. That's the feeling I wanted to bottle when I built the first version of defrag98.com back in 2024.
