Malik Piara has released an updated version of LogiCola 3, a modern port of Professor Gensler's 2008 Windows-only logic drill software, after two years of work. The new release restores infinite translation drills for mastery learning and reintroduces the original's colorful, playful visual style, responding to feedback from Hacker News, GitHub and email.
Jane Street released a puzzle challenging participants to reverse engineer an ASIC chip from just two files: a GDS layout file and a VCD file with example inputs and outputs. Kjartan van Driel and Leander Post worked through the challenge, breaking down how the chip's physical layout, organized into layers and reusable cells representing logic gates, could be decoded to understand its function without access to the original Verilog design.
A blogger with an engineering background details how they spent about a month reverse-engineering an ASIC chip design as part of a public puzzle set by trading firm Jane Street. The challenge involved analyzing a GDS chip-layout file to determine the chip's function, first through an easier warmup version with more design information, then a harder unaided version. The author has published their code on GitHub and plans follow-up posts explaining each technical step in more depth.
A data team encountered CronosPro database files (CroBank.dat, CroIndex.dat, CroStru.dat) that existing tools, including the open-source Cronodump converter, could not properly parse. Using OpenAI's Codex to analyze the binary structure, they identified parser bugs and an obfuscated schema, then patched the Cronodump codebase to correctly extract records for their data lake.
The developer behind the ImHex hex editor wrote a tutorial demonstrating how to reverse-engineer an undocumented binary file format, using the 2012 game FEZ's save file as the example. The walkthrough shows how to move from raw hex bytes to a complete structure definition written in ImHex's Pattern Language, a feature available on the free, open-source, cross-platform tool.
An engineer spent two weeks pointing an AI coding agent, Claude Opus 5, at the firmware and update tools of everyday USB peripherals—a microphone, a webcam, and a key light. The agent extracted a full command shell from the microphone, found a way to disable the webcam's recording LED while it still captures video, and discovered the key light accepts unauthenticated memory writes from any device on the same WiFi network.
