From PhoneNet to G.hn: A History of Home Networking

This article traces the evolution of home networking technologies from PhoneNet in the 1980s to G.hn today. PhoneNet, using phone lines for low-speed AppleTalk networks, pioneered home networking. HomePNA followed, leveraging pulse position modulation and QAM to increase speeds and attempting centralized networking in multi-unit dwellings. Finally, G.hn emerged as a more versatile standard, supporting phone lines, coaxial cables, powerlines, and fiber, finding widespread use in set-top boxes. While WiFi's rise has diminished reliance on these technologies, they remain relevant in embedded systems and ISP infrastructure.

Issues with Object-Oriented Programming in Guile

2024-12-30

This article explores the discrepancies between Guile Scheme's object-oriented programming system, GOOPS, and Common Lisp's Object System (CLOS), highlighting GOOPS's shortcomings. GOOPS lacks the elegance and robustness of CLOS in several key areas: setter specialization doesn't compose with inheritance, it lacks before/after/around method qualifiers, method combination algorithms are not controllable, method argument specialization is limited, keyword arguments are unsupported, and documentation strings are absent. The author suggests improvements such as mimicking CLOS behavior, adding method qualifiers, and enhancing method argument specialization to improve code elegance and reduce bugs.

Gmail's New Easy Encryption: Secure Emails with a Single Click

Google is updating Gmail to allow enterprise users to send encrypted emails to any inbox with just a few clicks. A new encryption model eliminates the need for custom software or certificate exchanges. Initially rolling out in beta for internal enterprise emails, the feature will expand to any Gmail inbox in the coming weeks and other providers later this year. Users simply toggle 'additional encryption' to send a secured message. Non-Gmail recipients receive a link to a guest Workspace account to view and reply securely. While offering stronger encryption than TLS, it's not true end-to-end encryption as Google retains control over encryption keys.

Solved: The Mystery of Sea Turtles' 'Lost Years'

Scientists have solved a long-standing mystery surrounding the 'lost years' of sea turtles. By attaching GPS trackers to young turtles in the Gulf of Mexico, researchers discovered that these creatures aren't passively drifting with ocean currents, as previously thought. Instead, the tiny turtles actively swim, navigating between continental shelf waters and the open ocean, making their own decisions about where to go. This research, published in Proceedings of the Royal Society B, fills a significant gap in our understanding of sea turtle life cycles and offers crucial insights for conservation efforts.
