"prep for Anthropic IPO" :)
Opus 5 is still a better deal.
Introducing Claude Fable 5.1 and Claude Mythos 5.1 \ Anthropic
Fable 5.1 cuts typical token-based costs by 25% while improving performance across coding, research, and reasoning tasks. Anthropic launches Fable 5.1 broadly and restricts Mythos 5.1 to trusted-access programs for advanced cybersecurity and biology work. Fable 5.1 reaches 52.6% on Terminal-Bench-Science, while Mythos achieves nearly 50% protein-binder hit rates.
This website contains all the lectures, project materials and tools necessary for building a general-purpose computer system and a modern software hierarchy from the ground up. The materials are aimed at students, instructors, and self-learners. Everything is free and open-source, as long as you operate in a non-profit setting. Here is a recent CACM article about the course: text / video.
Nand to Tetris courses are taught at 400+ universities, high schools, and bootcamps. The students who take them range from high schoolers to Ph.D. students to senior engineers. Here is an extended syllabus of a typical academic-version course.
A textbook with a hands-on approach that leads students through the gradual construction of a complete and working computer system including the hardware platform and the software hierarchy.
In the early days of computer science, the interactions of hardware, software, compilers, and operating system were simple enough to allow students to see an overall picture of how computers worked. With the increasing complexity of computer technology and the resulting specialization of knowledge, such clarity is often lost. Unlike other texts that cover only one aspect of the field, The Elements of Computing Systems gives students an integrated and rigorous picture of applied computer science, as its comes to play in the construction of a simple yet powerful computer system.
Plug In Balcony Solar Power Moves from Hack to Household - IEEE Spectrum
Balcony solar (plug-in photovoltaic panels that plug directly into standard wall outlets) is rapidly expanding in the U.S. following recent legalization in states like Utah, Colorado, Virginia, New York, New Jersey, and California. However, U.S. safety regulations and utility readiness are currently struggling to keep pace with this rapid adoption.
Wiring Hazards: Standard home outlets were designed for power to flow out, not in. Exposed plug prongs on active solar panels present electric shock hazards.
Bypassing Protections: Plug-in solar introduces power downstream of household circuit breakers, making existing safety switches "blind" to electrical overloads and potentially causing Ground Fault Circuit Interrupters (GFCIs) to fail.
Grid & Worker Safety: Uncertified systems may fail to shut off during local power outages, risking backfeeding power onto the grid and endangering line workers.
Germany’s Precedent: Germany pioneered balcony solar adoption, establishing clear regulatory standards by late 2025, banning net metering to protect grid management, and granting legal protections to renters wanting to install panels.
U.S. Certification Standard (UL 3700): Developed by UL Solutions, this standard addresses overcurrent protection, bidirectional current, and automatic blackout shutoffs.
Current Limbo: Because the standard is so new and demanding (e.g., requiring currently unavailable hardware like bidirectional GFCI disconnects), virtually no consumer panels on the market are UL 3700-certified yet (with rare recent microinverter exceptions).
Utilities like SoCal Edison emphasize that customers must notify them before installing balcony solar to ensure safety and aid grid balance. However, evidence from Germany shows unregistered "guerilla" installations outnumber registered ones 2-to-1, meaning safety standards must reliably protect systems regardless of user compliance.
