Ferroelectric memory (FRAM) is a nonvolatile storage technology that retains data without power, similar to flash memory, but offers faster writing speeds and greater durability, allowing for trillions of write cycles. Despite these advantages, FRAM is less popular due to its higher cost, limiting its use to niche applications. A recent examination highlighted a 64-kilobit FRAM chip from 1999 by Ramtron, showcasing its structure with memory cells made of ferroelectric material,

In the decades prior to the invention of x-rays and powerful microscopes, Lord Rayleigh calculated the size of a single molecule, drawing inspiration from Benjamin Franklin's early experiments with oil and water. In the 1770s, while in London, Franklin observed that pouring oil on turbulent waters calmed the waves, a practice known since ancient times. He conducted a controlled experiment on a windy day by pouring a small amount of oil onto a pond, noting how it spread across the surface and smoothed

The content discusses ways to enhance the readability of the C programming language while maintaining its fundamental nature. While C is recognized for its inherent challenges in aesthetics and readability, the author proposes methods to introduce some "prettier" elements without compromising its structure. Key points include: - C23 introduces booleans to the language, but the author offers a solution to implement them in earlier versions of C using macros. - The author provides a method to define boolean types manually, allowing for cleaner code with boolean

The book focuses on effective development practices in Java, emphasizing an approach known as Data-Oriented Programming (DoP). It advocates for organizing programs around "plain data," which leads to simpler, smaller, and more understandable code. The author notes significant changes in Java over recent years, with new features that support this programming paradigm. However, the book prioritizes fundamental concepts over tools, likening programming to house building rather than just learning to use a screwdriver. The core idea of DoP is that "

The author discusses the challenges of efficiently reading data from disk while working on a search engine, noting that improving performance often requires avoiding high-level tools. Although modern hardware is fast, the author emphasizes that performance hits can be significant, especially when dealing with large datasets, such as hundreds of gigabytes. A simplified benchmark is introduced, where the task involves reading 1 billion temperature measurements assigned to cities and aggregating them to find min, max, and average values. The focus is on achieving near RAM performance

The article discusses the complexities and best practices of indexing in PostgreSQL, emphasizing the importance of being cautious when creating indexes. The author shares a personal experience from a previous job where they managed a high-volume PostgreSQL instance. They initially improved query performance significantly by using the CREATE INDEX CONCURRENTLY command, which allows for indexing without locking out writes. However, after a new feature was launched that relied on the new index, performance issues emerged during a spike in traffic, leading to slow query responses and time

Trail of Bits critiques the continued use of RSA as a cryptosystem, highlighting its inherent fragility and vulnerabilities. Despite its common applications in public key encryption and digital signatures, RSA poses significant risks largely due to its complexity and the difficulty in avoiding common pitfalls. Issues such as weak parameters, poor performance, and the persistence of padding oracle attacks contribute to its unreliability. The process for implementing RSA requires careful selection of parameters, but past decades of security breaches suggest that correctly implementing RSA in practice is

The article discusses the evolution of environment variable management in Node.js, particularly highlighting the dotenv package, which has been a popular tool for loading environment variables from a .env file. However, with the introduction of Node.js version 20.6.0, users can utilize the new --env-file flag when executing scripts. This flag allows Node.js to read from an .env file before running a script, potentially reducing reliance on external packages like dotenv and streamlining the process of managing environment variables.
