The Good Thing About Hard Things calnewport.com/the-good-thi...
I've been vibe-hacking away on nvdisasm-re... Demo: huggingface.co/spaces/ejsch... Super complicated semantics coverage report: raw.githack.com/edmcman/nvdi...
blog.ploeh.dk/2026/10/12/r... I've also slowly transitioned from reading LLM-written code to focusing on tests and verification.
github.com/edmcman/nvdi... now has a SASS disassembler. More impressively, it actually wrote a script to generate SLEIGH from the nvdisasm tables. Most instructions only have data flow p-code semantics so far. I'm sad/excited to say that AI has surpassed my own personal capabilities.
Claude code with opus 5.5 medium and my fork of Ghidra MCP reverse engineered `nvdisasm` and extracted its internal tables for SASS instructions in about 10 minutes. What a wild world we live in. github.com/edmcman/nvdi... Next up: Can we generate SLEIGH modules?
I've been playing around with a light-weight dynamic decompiler verification: huggingface.co/spaces/ejsch...
dl.acm.org/doi/pdf/10.1... I'm happy to see others working on C++ recovery, because it's such a hard problem. But I'm pretty skeptical of this paper. The selling point of their paper, the "Object Flow Graph" is conceptually the same as OOAnalyzer. It's like they didn't read our paper?
I'm really enjoying the "Statistical Rethinking" course/book. It should be required reading for all researchers. oceanrep.geomar.de/id/eprint/55... github.com/rmcelreath/s...
arena.ai/blog/coding-... This is interesting. They find that harness has little impact on success, but significant impact on cost.
www.latent.space/p/attention-... 1. Interesting view of AI timeline 2. I agree that models and harnesses are being intertwined, and I'm not sure it's a good thing.
Well I'll be. NDSS is moving from San Diego! www.internetsociety.org/blog/2026/06...
Harbor's hub now lets you upload benchmark runs, which is pretty neat. Here's an example run from the auto-bench blogs I've been writing: hub.harborframework.com/jobs/4149711... You can view each run and its trajectory: hub.harborframework.com/jobs/4149711...
github.com/QwenLM/Qwen3... Something is wrong when outsiders need to reverse engineer how you are getting your published benchmarks.

www.reddit.com/r/ClaudeAI/c... AI providers are beginning to slow down their subsidies on LLM usage. For now, it is only external agents like Opencode. But LLM access as a subscription model is a loss leader. All these vibe coders are going to be very upset when they have to pay per token.
I designed my first real part! www.printables.com/model/162187... No, I don't really know what I'm doing. Yes, it is satisfying anyway!
We live in such a wild time. theshamblog.com/an-ai-agent-...
openai.com/index/harnes... "What’s become clear: building software still demands discipline, but the discipline shows up more in the scaffolding rather than the code. The tooling, abstractions, and feedback loops that keep the codebase coherent are increasingly important."
