Radicle, an open source peer-to-peer code collaboration stack built on Git, has disclosed a security vulnerability within its network protocol. The flaw affects the underlying communication system of the decentralized platform. Developers using the forge are encouraged to review the disclosure details and take appropriate security measures.

Prompted by an article on Z80 REPLs, readers share nostalgic memories of the built-in assemblers and monitor programs found in classic 8-bit computers like the Apple II, Commodore 64, and BBC Micro. Many commenters recall how these early, integrated environments were crucial tools for learning to program and reverse engineering software. The conversation also touches on the technical implementation of these features, such as the non-maskable interrupts used by freezer cartridges to invoke monitor routines.

Microsoft discontinued Visual FoxPro in 2007, but developers have now revived the legacy programming environment. The new project provides a 64-bit runtime and modern IDE for existing Visual FoxPro 9 applications. This rebuild reconstructs the original language using contemporary technologies, including Electron, React, and a Rust-based WebAssembly virtual machine.
