OxCaml is both a production compiler developed by Jane Street and a platform for experimenting with enhancements to the OCaml programming language, aimed at improving its suitability for performance-oriented programming. The objective is to create extensions that provide optimization capabilities without adding unnecessary complexity—essentially a "pay-as-you-go" model. OxCaml ensures compatibility with existing OCaml code, allowing all valid OCaml programs to function as valid OxCaml programs, while evolving OCaml’s design principles to enhance safety, ease

Dr. Cat Hicks delivered a compelling presentation at the Craft Conference in Budapest, highlighting the systemic issues facing developers in modern tech organizations. Many developers feel unseen and unprepared for rapid changes in their work environment, with a stark disconnect between their experiences and the perceptions of engineering managers—88–90% of whom believe they make developers’ work visible, while only 24% of developers feel this is true. Additionally, around 43–45% of developers are anxious about AI potentially making their skills obsolete

Aim Security has discovered a serious vulnerability named "EchoLeak" in the M365 Copilot, an AI-driven tool that retrieves data from users' organizational environments. This zero-click attack allows attackers to exfiltrate data without user interaction by exploiting design flaws typical of Retrieval-Augmented Generation (RAG) Copilots. The attack chain consists of three main vulnerabilities, with additional potential weaknesses identified. M365 Copilot uses OpenAI's GPT to enhance business-related tasks by responding to user queries with relevant

The blog post from Codeminer42's Engineering Blog discusses the significant impact of Ruby on Rails (RoR) since its launch in 2004. Created by David Heinemeier Hansson as an open-source framework within the Basecamp codebase, Rails revolutionized web development by making it easier and faster to build applications, including blogs. The framework is rooted in several core principles encapsulated in "The Rails Doctrine," which emphasizes productivity, developer joy, sensible defaults, and a cohesive tooling approach

Bert, a Rails engineer, encountered performance issues due to the handling of encrypted data in his event store database using RailsEventStore's EncryptionMapper. The encryption process relied on an external KMS for key retrieval, leading to significant delays from network calls for each encryption/decryption operation. While caching keys was a potential solution, the vast number of events and keys made it impractical. Bert proposed a PR to introduce batch mapping, allowing multiple events to be processed simultaneously, which improved performance. This feature

A.O. Scott reflects on Kay Ryan's poem "Turtle," examining its unique perspective on the life of a turtle. The poem combines humor and keen observation, depicting the turtle's challenging existence shaped by its shell. Ryan's writing style mirrors the turtle's slow, deliberate movement, using heavy rhymes and alliteration to convey both the creature's dignity and the absurdity of its life. Through her vivid language, Scott emphasizes that while turtles may not possess the charm of other animals, they have

The field of time-series forecasting is evolving, shifting from traditional statistical methods (like ARIMA and Prophet) to the use of foundation models, which leverage large language models (LLMs) for enhanced flexibility and power. This shift aims to eliminate the need for separate forecasting models for different datasets and scenarios, as creating tailored models can be cumbersome and inefficient. Parseable addresses the challenges of managing observability data by using these advanced models to avoid the manual overhead of hyperparameter tuning and model retraining, which

On October 23, 2023, Google Cloud's Identity and Access Management (IAM) service experienced a glitch at 10:50 AM PT, leading to widespread authentication failures across various Google Cloud Platform (GCP) products. This incident impacted Cloudflare's Workers KV, which relies on Google's backing store, disrupting services like Access and WARP. Anthropic, operating on GCP, faced issues with file uploads and elevated error rates. The root cause was identified as a problematic rollout of the

The author discusses their ongoing exploration of real-time text rendering, expressing previous dissatisfaction with various methods, including issues like aliasing and texture management. They previously used Multi-Channel Signed Distance Fields (SDFs) effectively, but still found aspects unsatisfactory. A new OLED monitor prompted them to revisit the topic, particularly due to the monitor's fringing issues. Engaging in a GitHub discussion inspired them to implement glyph rendering with subpixel anti-aliasing. They conducted tests using various font styles

The jemalloc memory allocator, created in 2004 and publicly available for nearly 20 years, has halted active development despite remaining accessible as open-source software. This summary outlines its development journey, beginning with the Lyken programming language, which aimed to incorporate a manual memory allocator. Although Lyken was ultimately not completed, its allocator was integrated into FreeBSD, leading to the removal of the allocator from Lyken in 2006. This decision stemmed from the realization that the system allocator only required

Security researchers discovered that Kremlin-backed disinformation campaigns are exploiting malicious advertising technology to evade moderation on social media. A report by Qurium revealed the resilience of this dark ad tech industry, focusing on a disinformation network called “Doppelganger.” This network promotes pro-Russian narratives by using cloned websites and sophisticated “domain cloaking” techniques, which allow it to serve different content to search engines and regular visitors. This method helps the disinformation maintain a longer online presence. Qurium's investigation

The author expresses concern about the potential obligation for software engineers to pay subscription fees for AI coding tools. While many professionals can afford these fees, the author argues that the use of AI fundamentally alters the nature of coding and raises questions about the appropriateness of charging for tools that are essential to the profession. The comparison is made to other creative fields where tools are expensive, suggesting that such a shift could hinder efficiency and progress in software engineering. Ultimately, while AI tools could enhance productivity, the author wishes to

GitHub Actions, a continuous integration/continuous deployment (CI/CD) tool, includes a policy mechanism to restrict the types of actions and reusable workflows that can be employed within repositories or organizations. However, this mechanism is easily bypassed, and the author believes this poses a security risk, a view that GitHub does not share. Users of GitHub Actions must be cautious about what actions and workflows they trust since CI/CD tools allow execution of arbitrary code, which can potentially access sensitive data or modify repositories

The passage discusses frustrations with frequent re-login requirements and multi-factor authentication (MFA) challenges that disrupt workflow and lead to MFA fatigue, making users more vulnerable to phishing attacks. It highlights a shift in understanding security practices, noting that constantly changing passwords and frequent logins are not effective strategies. Instead, security should focus on how access is managed and the ability to quickly respond to policy changes. There are two main types of authentication: Identity Providers (IdPs), which verify user identity, and integrated authentication
