Ruby 3.4 introduces a new method called `Array#fetch_values`, which allows users to safely retrieve multiple elements from an array with support for default values. Previously, accessing multiple indices required handling potential nil values or multiple fetch calls, which became unwieldy, especially when different default values were needed for different indices. `Array#fetch_values` simplifies this process by allowing users to fetch multiple elements in one call while maintaining safety. It also supports dynamic default values through a block form, making

California Governor Gavin Newsom recently signed a bill mandating that web browsers simplify the process for Californians to opt-out of third-party data sales. While the California Consumer Privacy Act (2018) allowed residents to send opt-out signals, it did not require browsers to make the process user-friendly. The new law, which passed the legislature on September 11, provides an easy-to-find mechanism for opting out with a single action. This legislation is the first of its kind in the U.S.,

Discord has reported that approximately 70,000 users may have had their government ID photos exposed due to a breach by a third-party customer service provider, Zendesk. A group claiming to have 1.5TB of age verification-related photos is attempting to extort Discord. A spokesperson, Nu Wexler, clarified that this incident does not constitute a breach of Discord itself, and the figures being circulated by the attackers are inaccurate. Discord has emphasized that they will not pay the extortionists for

The author reflects on the past decade of RubyGems and its informal governance, highlighting the need for a balance between open-source ideals and economic realities. They initially expected Ruby Central to bridge this gap but realized that informal projects often fall prey to the dominance of formal organizations, which are seen as more legitimate. This imbalance led to negative consequences for RubyGems, forcing the community to distance itself and start anew. The author emphasizes that a system assuming equality can perpetuate existing inequalities and encourages the community to

This blog post is part of the "Hanami for Rails Developers" series, focusing on building applications with the Hanami framework. In previous parts, the author discussed how Hanami structures models and controllers, dividing responsibilities into repositories, relations, structs, actions, views, and templates. This installment centers on adding a form to allow users to add books to the application. The process begins by creating new and create actions for books, using the existing BookRepo class for book creation and implementing data validations within

The five leading JavaScript frameworks—Angular, React, Vue, Svelte, and Blazor—utilize different rendering strategies, which impacts their performance. Although many benchmarks claim to compare these frameworks, they often are oversimplified or make unfair comparisons, such as contrasting a comprehensive framework with a basic library. The author is currently embarking on a new web application development project and sought academic studies to inform their choice of framework but found limited resources. They did discover a 2021 study comparing the

Julia version 1.12 has been released, with gratitude extended to contributors and testers for their involvement. Key highlights of the release include: 1. **Experimental --trim Feature**: This feature allows the compiler to remove statically unreachable code when building a system image, improving compile times and reducing binary sizes. It requires the --experimental flag and must avoid dynamic dispatches in reachable code. 2. **Bindings and World Age Mechanism**: The new version allows bindings to participate in the "world

Kendra Little shares her experiences with poor performance from cloud vendors, specifically highlighting issues with Azure SQL Managed Instance's General Purpose Tier. She notes that while the service previously claimed storage latency of "5-10 ms," a recent update acknowledged that this is merely an average and that outliers exceeding this range are possible. Little reports encountering latency issues in real-time, with instances showing delays of up to 60 seconds, though Microsoft has not specified a maximum latency limit. This raises concerns about the reliability of

In November 2024, the author wrote a blog post on Python's performance, observing its improvements over time. As of October 8, 2025, following the release of Python 3.14, they are rerunning benchmarks. The author notes that while they will share benchmark results, generic benchmarks are not necessarily indicative of overall performance due to the complexity of the Python interpreter. The tests focus on pure Python code, avoiding dependencies and C code, as these are less likely to show performance

Cloudflare has reported that it processes 84 million HTTP requests per second across its data centers. This scale led to the discovery of a bug in Go's arm64 compiler, resulting in a race condition in the code. The issue was first observed through sporadic panics on arm64 machines in a service responsible for traffic configuration for products like Magic Transit and Magic WAN. Initial investigations suggested rare stack memory corruption due to a fatal error related to stack unwinding. Although it was initially deemed a low priority
