Time travel debugging, introduced by tools like Undo, revolutionizes hardware design debugging by allowing engineers to record, replay, and resolve bugs in a Linux process from the process level down to individual CPU instructions. This method eliminates the need for repetitive simulation runs and guesswork, enabling engineers to navigate freely forwards and backwards in time to pinpoint root causes. The tool is particularly effective in complex scenarios like race conditions, deadlocks, and intermittent failures common in hardware modeling. Undo offers production-grade reliability, multithreading support, and seamless integration with modern EDA workflows, significantly reducing debugging time and improving team efficiency in resolving issues in hardware designs.

Commodore backs down over FPGA firmware lockdown — it won’t now try and block third-party firmware installs but will stand firm against bricked modded units

Commodore has reversed its decision to block third-party firmware installs on the C64 Ultimate computer, allowing users to experiment freely. However, the company will not provide support or replacements for modded units that become bricked. The initial plan to restrict non-Commodore FPGA firmware caused a divide among fans, leading to heated discussions on social media and forums. Commodore now emphasizes user freedom but warns that using community-installed firmware is at the owner's risk, with no free support or warranty service provided for damaged units.

Steam Controller leaked review points to $99 MSRP — more expensive than PS5 and Xbox controllers and Nintendo Joy-Cons

A leaked review of the Steam Controller revealed a $99 price tag, making it more expensive than controllers for PS5, Xbox, and Nintendo. The controller features dual trackpads, which the reviewer highlighted as a standout feature. Valve announced the Steam Controller alongside other hardware in late 2025, but due to the chip crisis, the release has been delayed to the first half of 2026. Despite its higher price, the Steam Controller's unique features, like dual touchpads, make it a compelling option for PC gaming. Valve has yet to announce an official release date for its new hardware lineup.
