Apple uses homomorphic encryption to enable private search in Photos app without revealing user data, but due to performance constraints, they use a modified version called somewhat homomorphic encryption. This approach allows the server to process queries without knowing the actual data, but still raises concerns about data ownership and the potential for leaks.
In this podcast series, the FMA Team will shine a spotlight on Free Music Archive's artists, FMA's very own music insiders, as they share with us a little bit about their music journey.
Data scientists use vector embeddings to compare similarities, but cosine similarity can be misleading due to its simplicity and lack of nuance. A better approach is to use task-specific embeddings or preprocess text before embedding it to get more accurate results.
customasm is an assembler for custom instruction sets. It can be installed via cargo install customasm or compiled from source with cargo build.
The user transitioned from Google to Proton services, but had issues with Proton Calendar, specifically with exporting and syncing calendars. They were unable to add events to their calendar from other apps due to Proton's limitations.

rqlite uses a testing pyramid with unit tests as the foundation, integration tests in the middle, and end-to-end tests at the top. This approach ensures efficient, targeted, and easy-to-debug tests, maintaining high quality and reliability in the distributed relational database.
A digital tool supports disaster recovery by organizing insurance claims, tracking expenses, and providing emotional support. It's based on a system used after the 2003 Cedar Fire and can be customized and expanded.
DynamoDB transactions use an optimistic concurrency control scheme with timestamps to ensure predictability and high performance at any scale. The one-shot transaction protocol allows for serializability and flexibility in modeling business transactions with read-only and write transactions.
The author's daughter struggled to learn bike riding with the traditional method, but a new approach worked better. The new method involves removing pedals and teaching balance by running and coasting before adding pedaling.
Pyper is a flexible framework for concurrent and parallel data-processing based on functional programming patterns, providing an intuitive API for unifying threaded, multiprocessed, and asynchronous work. It allows users to define pipelines of tasks using the `pyper.task` function and execute them concurrently or in parallel using workers and queues.
Researchers developed Transformer², a self-adaptive machine learning system that adjusts its weights for various tasks, enabling LLMs to dynamically adapt to new tasks in real time. This system outperforms traditional approaches in efficiency and task-specific performance, promising a future where AI models are no longer static.
The user created a custom LED display for their Raspberry Pi NAS server inspired by nostalgia for old mainframe computers. They designed and built 2U panels with 128 LEDs, using PIC16F1782 microprocessors and shift registers, and shared the design and code online for free.
Cosmos is a keyboard design tool that uses phone camera scans to create custom keyboards with ergonomic layouts. It supports various switches, keycaps, and microcontrollers, and exports to 3D printable models.
The author, a former homeschooler, criticizes tech parents for viewing homeschooling as a high-status option, citing its historical association with academic freaks and religious extremists. They argue that homeschooling can isolate children from average people and hinder their social development.
MIT researchers created a photonic chip that can process photons directly, achieving a latency of 410 picoseconds, which is 58 times faster than a standard CPU. This chip can be used for applications requiring fast processing, such as self-driving cars and automotive vision systems.
Simplex builds tools for developers to control the web using natural language.
A father-son project built a custom Corvette simulator using a 1980 Corvette donor car, aluminum frame, and gaming components. The project involved extensive modifications, including welding, fiberglass repair, and upholstery, to create a unique gaming experience.
This blocklist removes low-quality websites from search results and aims to be organized with issue explanations for each blocked site. It's a subscription-based list that stays up to date and allows users to contribute by creating issues.
Michael Frank left Sandia National Laboratories to join Vaire Computing, a startup working on reversible computing, which could offer up to a 4,000x energy-efficiency gain. Vaire's first prototype is expected to recover energy used in an arithmetic circuit, with a more advanced chip planned for 2027.
A Google authentication flaw allows attackers to access old employee accounts by purchasing a failed startup's domain and using it to recreate email accounts. Millions of Americans' data and accounts remain vulnerable until Google implements a fix to add immutable identifiers to its OpenID Connect claims.
Scientists have found that plants absorb 31% more carbon dioxide than previously thought, with 157 petagrams of carbon per year removed from the atmosphere via photosynthesis. This new estimate improves Earth system simulations and highlights the importance of natural carbon sequestration for greenhouse gas mitigation.
structured-logprobs is a Python library that enhances OpenAI's structured outputs with detailed token log probabilities. It provides insights into the reliability of LLM outputs and works with OpenAI's Structured Outputs feature.
Marimo is a free online playground for creating and sharing WebAssembly notebooks, ideal for experimenting and prototyping. Notebooks can be saved, shared, and embedded in web pages with various customization options.
The user rewrote their website using plain HTML and CSS due to frustration with SvelteKit's bundler and building ecosystem. They achieved a simpler project tree and a 50% reduction in website size, but face challenges with code duplication and live reloading.
A glossary was created to connect fragmented GPU documentation concepts. It's a hypertext document with linked pages for easy navigation and understanding.
