A computer scientist suggests using an algorithm called CVM to count unique animals or users, which requires remembering only a small number of entries instead of the entire list. The CVM algorithm solves the distinct elements problem by relying on randomization and can efficiently monitor a stream of elements without exceeding available memory.

The Starlink satellite service uses a unique combination of technologies, including phased array antennae and dynamic channel rate control, to provide internet connectivity with varying signal quality and latency. The TCP protocol's performance over Starlink connections is affected by factors such as packet loss, jitter, and satellite handovers, requiring optimization techniques like BBR or ...

Rate limiting algorithms control traffic to services by blocking requests that exceed a set limit during a period. Three common algorithms are fixed window, sliding window, and token bucket, each with its own pros and cons for handling bursts and average rates of requests.

Researchers have discovered an ancient branch of the Nile River, named Ahramat Branch, which once flowed near many major pyramid sites in Egypt. The discovery suggests that ancient Egyptians may have used boats to transport building materials rather than carrying them over land, providing new insights into their construction methods and daily life.

The article discusses simplifying JOIN code by treating foreign keys as dimension tables, eliminating Cartesian products and making queries more intuitive. It introduces two methods: Interconnection of homo-dimension tables and sub table set-lization, which simplify complex joins and reduce errors.

A neural network generates realistic chess positions, optionally constrained by preset pieces, with adjustable temperature and piece count. The tool can be used to practice specific pawn structures in various game scenarios against humanlike AI at chosen skill levels.

The project applies patches to Arch Linux source packages, aiming to upstream them for RISC-V (riscv64gc) support. The project provides various resources, including patch repositories, binary package repositories, and Docker images, with a contributing guide available.

Urban renewal policies in the US, which aimed to revitalize cities by bulldozing low-income areas, have led to persistent infrastructure issues and a lack of trust in government projects. The legacy of urban renewal continues to hinder efficient development and planning, with excessive public process and veto points perpetuating inequitable outcomes and slow project delivery.

The Soviet Union's watchmaking industry was once renowned for producing high-quality, affordable timepieces that rivaled those from Switzerland, with brands like Raketa, Poljot, and Vostok gaining popularity worldwide. Despite its decline in the 1980s and eventual collapse in 1991, Soviet watches remain sought after by collectors today for their unique history, craftsmanship, and nostalgic value.

Gemini API's context caching feature reduces request costs by caching repeat content with high input token counts. It's a paid feature, billed based on cache token count and suitable for scenarios with repeated references to initial contexts.

American land-use reformers aim to address housing shortages by amending zoning codes and building codes, specifically allowing single-stair apartment buildings, which were once common in the US but are now banned due to fire safety regulations. By re-legalizing these designs, multifamily housing can be built cost-effectively on urban sites that would otherwise be developed as single-family homes.

Big batteries are increasingly replacing gas-fired power plants in the US, with battery storage capacity expected to surge from 1% to 23% of new additions this year. The shift is driven by declining demand for gas and increasing investment in solar, wind, and battery production, which will help accelerate the transition to a fully clean power grid.

DeviantArt, a 24-year-old social network for artists, has been accused of promoting artificial intelligence-generated art and allowing bots to buy and sell artwork on its platform, leading to outrage among its community. The site's A.I. integrations have also led to lawsuits from artists who claim their work was scraped without permission and used to train generative-A.I. models, highlighting ...
