Lion Cove is Intel’s new high-performance CPU architecture, succeeding Raptor Cove. It offers improvements such as increased instructions per cycle, restructured execution engines, and an additional data cache level. These enhancements lead to notable performance gains in the SPEC CPU2017 benchmark suite, especially in higher IPC categories. In the Arrow Lake platform, Lion Cove competes well against AMD's Zen 5 and performs better than Raptor Cove, all while consuming less power. For gaming performance, tests were conducted using

Let’s Encrypt has announced that it has issued its first certificate for an IP address, a feature that has been frequently requested since its inception in 2015. Previously, only a few certificate authorities offered the ability to obtain certificates for IP addresses. This new option will be gradually rolled out to more subscribers over time. IP addresses serve as the fundamental numerical identifiers for devices on the Internet, with both IPv4 and IPv6 formats. While users typically interact with domain names, IP addresses are used behind the

The rise of "therapy-speak" is negatively impacting how we discuss romance, relationships, and personal identity. This therapeutic culture categorizes and labels every personality trait as a problem, making individuals feel that their natural behaviors and feelings are indicative of disorders. A survey showed that a significant portion of Gen Z girls view mental health challenges as part of their identity, a stark contrast to Boomers. This trend reflects a broader modern tendency to explain all aspects of human behavior through psychological and scientific frameworks. Consequently,

Universities have been established for over a millennium, yet they were not traditionally centers for research, particularly before the 19th century. In 1800, significant scholarly work was primarily associated with institutions like the British Royal Society and the French Académie des sciences, while universities were considered outdated, particularly in the German-speaking regions. However, at the turn of the 19th century, German universities adopted a novel approach that integrated teaching with research, rapidly becoming influential in various scientific fields. They led

The author expresses a passion for working on the Rust compiler, specifically focusing on a significant project this summer: bootstrapping the Rust compiler using `cg_gcc` instead of LLVM. Bootstrapping refers to the compiler build process, which consists of three stages. Initially, they use a pre-existing LLVM-based Rust compiler to build a GCC-based code generator. Subsequently, they rebuild the Rust compiler using this GCC codegen, and for verification, they compile it again to ensure both builds produce identical execut

Crypto 101 is a free introductory course on cryptography designed for programmers of any age and skill level. It covers essential concepts like SSL/TLS, block and stream ciphers, hash functions, message authentication codes, public key encryption, key agreement protocols, and signature algorithms. The course also teaches how to exploit common cryptographic weaknesses, enabling learners to perform tasks such as forging administrator cookies and recovering passwords. Originally presented at PyCon 2013, Crypto 101 has evolved into a comprehensive resource that

The author presents a challenge related to adding a new column, `utr_number`, to a transaction table containing approximately 1 billion records. The `utr_number` needs to be reconciled with values obtained from an API that responds in about 100 ms and has rate limits of 10,000 calls per minute, along with potential uptime issues. To tackle the problem, the author suggests a batching approach: loading and processing records in manageable groups of 5,000 to avoid overwhelming the database and to

Ruby 3.4 introduces the `it` parameter as a clearer alternative to numbered parameters like `_1`, specifically for single-argument blocks. This change aims to improve code readability while maintaining performance. The adoption of the `it` parameter was driven by concerns over the cognitive load associated with remembering numbered parameters. The Ruby core team addressed potential conflicts, particularly with RSpec's `it` method, by gradually rolling out the feature: Ruby 3.3 will issue warnings, while 3

A security researcher, Sharon Brizinov, discovered sensitive information in deleted GitHub commits, including a personal access token that granted admin access to all Istio repositories, which are crucial for many enterprises. This discovery led to around $25,000 in bounties. The investigation highlighted the challenges developers face when they accidentally commit sensitive data (like passwords) and later attempt to delete those commits. Git's design preserves commit history, and while developers can use a force push to rewrite history to remove the

jank is a general-purpose programming language that serves as a strongly compatible dialect of Clojure. It combines the interactive and value-oriented nature of Clojure with native compilation and minimal runtimes, operating on C++ with an LLVM-based JIT for improved performance. While maintaining Clojure's core features, such as code-as-data philosophy and powerful macros, jank focuses on functional programming with persistent, immutable data structures. It also includes software transaction memory and a reactive agent system for managing mut

The author discusses a solution for synchronizing JavaScript/React state management across multiple Tauri processes (windows) using the Zustand library. While developing an application called Hopp, they faced challenges with state management in a multi-window environment, where both the main control panel and a separate window for screen-sharing needed to share and sync state. Instead of managing state purely on the backend to maintain reactivity, they opted for a loosely synced approach to avoid excessive complexity and ensure that components remained reactive without being burden

Open Policy Agent (OPA) is a powerful tool for enforcing Kubernetes policies, providing precise control to keep clusters secure and consistent. While Kubernetes allows for code-based resource management, it lacks built-in mechanisms to detect errors in configurations, which can lead to security vulnerabilities. OPA addresses this by enabling administrators to define and enforce admission control checks that ensure resource definitions adhere to specified criteria, helping to prevent configuration errors and maintain consistency within Kubernetes environments. OPA operates using a policy-as-code approach, allowing users to write

The July 2025 release of C3, version 0.7.3, focuses on refining the language, particularly its compile-time components. Key improvements include enhanced ways to inspect and manipulate types through direct type use and typeid values, allowing constant typeids to be used directly for implicit type conversion. This change simplifies macro code by eliminating the need for converting typeids to types, leading to clearer syntax. Additionally, the $assignable builtin has been updated to accept both types and typeids

The excerpt discusses the uncertainty people felt about why objects remained on the ground and why celestial bodies like the moon did not fall to Earth. This uncertainty was addressed in Isaac Newton's 1687 work, "Philosophiæ Naturalis Principia Mathematica," which explained fundamental principles of motion and gravity. The book, funded by Edmund Halley, provided a scientific framework that replaced vague beliefs about gravity with clear laws that could predict the behavior of objects, both large and small. Newton's laws have

Matthias Winkelmann's company opted for outsourcing to reduce costs, handing off development work for a fixed-bid project to an overseas firm with lower hourly rates. In-house programmers were restricted from providing technical support, only assisting testers in communicating issues, which led to significant challenges. One major problem involved a security vulnerability (SQL Injection) that the in-house team identified and communicated but the overseas team struggled to understand. Despite passing helpful resources, multiple weeks of back-and-forth testing revealed persistent issues,

Jake Gold explores the effectiveness of 90s-era CGI in modern web development, demonstrating that with a Go + SQLite CGI program running on a 16-thread AMD 3700X, it's possible to serve over 2400 requests per second or over 200 million requests daily. Reflecting on his early web development experiences with CGI, Gold notes how CGI instigated heavy overhead by starting a new process for each web request, prompting the evolution of more efficient technologies like PHP and FastCGI.
