The author is undertaking a project to develop "Bridgetris," a game for the vintage 1985 BBC Bridge Companion console originally intended to teach bridge via television. To achieve this, the creator must master Z80 assembly language, reverse-engineer the system BIOS to allow custom code execution from cartridges, and perform hardware modifications like composite video integration.
- The device uses the TMS9129 VDP which features 16kB of VRAM.
- Original retail price was approximately £200 in 1985.

The z386 project aims to implement the Intel 80386 processor core on an FPGA. Recent optimizations have significantly improved its performance, including the implementation of early start memory access and a reduction in branch jump cycles from 9.25 down to six through microcode refinements. These changes resulted in approximately a 39% increase in DOOM benchmark scores, though the project still falls short of original hardware speed and cannot yet boot Windows.
- Implementation of early start memory access for FPGA cores
- Optimization of store queues and branch jump timing
- Significant performance gains in gaming benchmarks

Meta is addressing high DDR5 memory costs by repurposing legacy DDR4 modules from decommissioned servers. Through a custom-developed Vistara ASIC, the company can attach old DDR4 memory to modern servers running AMD EPYC Turin processors that natively only support DDR5. This CXL 2.0 implementation allows for expanded memory capacity by using DDR4 as a secondary, slower tier for cold data while keeping frequent data in fast DDR5.
- Meta's Vistara ASIC bridges legacy DDR4 with modern DDR5 servers
- CXL 2.0 technology enables tiered memory management via NUMA nodes
- Panmnesia offers scalable CXL controller and switch solutions for data centers
- Strategy aims to mitigate rising DRAM prices and hardware costs

Linux kernel developer Greg Kroah-Hartman has introduced a new fuzzing tool and AI bot named gregkh_clanker_t1000 that is actively uncovering bugs within the Linux kernel. The tool has already assisted in merging nearly two dozen patches for various subsystems including ALSA, HID, SMB, Nouveau, and IO_uring. Notably, this AI operates as a local large language model (LLM) running on a Framework Desktop powered by AMD Ryzen AI Max (Strix Halo), rather than relying on cloud-based services.
Key points:
* The gregkh_clanker_t1000 tool has contributed numerous bug fixes to the mainline kernel since early April.
* The system utilizes local LLM processing for privacy and efficiency.
* Hardware setup involves a Framework Desktop with AMD Ryzen AI Max+ Strix Halo.
* Emphasis on using an open-source software stack for demanding AI workloads.
