Introduced in 1980, the Intel 8087 math coprocessor significantly accelerated floating-point operations for the IBM PC and other early computer systems. By offloading complex addition and subtraction tasks from the main CPU, the chip greatly improved computational performance and paved the way for advanced personal computing.

Autodesk attempted to trademark the term cyberspace, which angered author William Gibson after he popularized the phrase. Rumors soon spread that Gibson retaliated by trademarking the name of Autodesk's Eric Gullichsen. However, this story of retaliation was actually a prank orchestrated by Timothy Leary.

Running a dedicated LLM proxy is essential for developers who need full visibility and control over their large language model integrations. Without a proxy, teams building everything from small projects to enterprise SaaS applications risk losing critical insights into model behavior, costs, and API usage.

The article argues that developers waste valuable time building personal software factories to automate their individual workflows. Instead of creating highly customized development pipelines, engineers should rely on existing tools and focus their efforts on actual product development.

Researchers have uncovered a critical vulnerability in Broadcom's proprietary WPS implementation that allows unauthenticated attackers within WiFi range to achieve remote code execution on millions of routers. Discovered via agentic vulnerability research, the flaw impacts both eCos and Linux platforms and was accompanied by a notably unusual disclosure process.

A new open-source project provides a read-only MCP server that allows AI agents to search and read personal WhatsApp messages. The tool runs entirely for free on Cloudflare Workers. This gives developers a simple and cost-effective way to integrate their personal chat data into AI workflows.

The LT6502b is a custom-built laptop that brings vintage 8-bit computing into a modern portable form factor using a 10MHz 65C02 processor and 46KB of RAM.
