The article discusses the author's upcoming talk at the SF Ruby Conference, focusing on improving application development speed by minimizing code loading in Ruby. The author explores Hanami, a web framework, to understand its approach to code loading. In Ruby, constants are globally accessible singletons, meaning every time a constant is defined, Ruby loads and evaluates related code, which contributes to slow application boot times. The key to enhancing development speed is to reduce the amount of code loaded upfront. By deferring the loading of

Ruby Central has published a post-incident review regarding a security event involving AWS root access that occurred in September 2025. The incident was initially highlighted in a blog post on September 30th, raising concerns that a former maintainer still had access to the RubyGems.org production environment despite the revocation of administrative access for several accounts. The review outlines the investigation's findings, emphasizing that while there was no evidence of harm to user data or operations, the presence of unrevoked credentials and

The article discusses SQLite's main limitation regarding write concurrency, highlighting that it allows for unlimited readers but only a single writer at any given moment due to its Write-Ahead-Log (WAL) journaling mode. This results in serialized write operations, which can lead to delays during the fsync operation essential for data durability. In contrast, database engines with server components can manage concurrent writes more efficiently by batching them together. The author also mentions that they are developing a new concurrency model aimed at improving

A joint study by the UK AI Security Institute and the Alan Turing Institute found that only 250 malicious documents can create a "backdoor" vulnerability in large language models, regardless of the model's size or the volume of training data. This challenges the assumption that attackers need a significant percentage of training data to execute data-poisoning attacks, suggesting instead that a small, fixed amount can suffice. The study specifically focused on a narrow type of backdoor that produces gibberish, considered low-risk

In a recent discussion at the Intel Tech Tour 2025 in Phoenix, Arizona, Stephen Robinson, the Lead Architect for x86 Cores at Intel, shared insights on the company's upcoming Panther Lake and Clearwater Forest CPUs. In the conversation, he highlighted the significant developments from the previous Crestmont architecture to the new Skymont architecture. Key improvements include enhancing the out-of-order execution depth by approximately 50%, increasing load ports from two to three, and doubling vector hardware from two FMAs to four

The content discusses the process of creating a one-handed chorded keyboard (referred to as a keyer) and emphasizes the importance of user feedback. It mentions a troubleshooting note about errors loading the page and points out resources such as documentation for qualifiers. The keyer project involves building a structural framework using copper wire to hold key switches, contrasting traditional devices that use external casings. Detailed initial steps for constructing the keyer include forming a metal scaffolding, creating a ground loop with wire, and solder

Daniel Lemire’s blog post discusses the necessity of SIMD (Single Instruction, Multiple Data) instructions, providing a brief history of CPU architecture and SIMD's development in the x86 platform. The term SIMD was introduced in 1966 as part of Flynn's Taxonomy, which categorizes computer architectures. Early discussions on parallelism stemmed from Gene Amdahl's 1968 letter, which highlighted the limitations on overall program speedup due to non-parallelizable serial parts, encapsulated in “

The author discusses insights gained from Steve Downey's talk at CppCon 2025 about the new range API for `std::optional`, specifically `std::optional<T&>`. Initially skeptical, the author explores the unexpected utility of iterating over an `optional`, which allows for loops that execute either zero or one time. They compare this to traditional pointer semantics but highlight the range-based approach's benefits, particularly in simplifying code by avoiding manual null checks. The author cites an example from proposal

The article discusses the advantages of using a local Docker registry to store and manage Docker images, instead of relying on DockerHub. Key benefits include cost savings, improved speed for image handling, enhanced security by minimizing exposure to the public internet, and reduced setup complexity when using Kamal for deployment. However, a significant drawback is that the local registry is limited to the specific Kamal installation and cannot be easily shared with coworkers. This feature requires using Kamal's main branch and Docker version 28.3

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.,
