On November 12, 2024, Canva experienced a critical outage that rendered canva.com unavailable from 9:08 AM to approximately 10:00 AM UTC. The outage was primarily caused by the failure of the API Gateway cluster due to a combination of factors: a software deployment for Canva's editor, a locking issue, and network problems with Cloudflare, the company's CDN provider. This report outlines the root cause, timeline, mitigative actions taken during the outage, and future preventive measures

The content emphasizes the importance of user feedback and encourages readers to consult the documentation for available qualifiers. It discusses a project that is largely based on a raycasting tutorial, providing navigation instructions (using arrow keys and 'q' to quit) and links to additional visuals. The primary issue noted is that executing commands in Bash is extremely slow, making it challenging to achieve acceptable frame rates for graphical output. It addresses limitations in Bash, such as the lack of floating-point support, reliance on integer math, and

Elixir v1.18 introduces significant improvements in set-theoretic types and language servers, along with built-in JSON support and enhancements to its unit testing library. The release continues the effort to implement static types in Elixir, characterized by a sound, gradual, and developer-friendly type system. The type system allows the use of the `dynamic()` type for runtime type checks and provides flexibility in type composition, enabling complex conditions like `dynamic(integer() or float())`. The previous version, v

Jeaye Wilkerson is the creator of the jank programming language, a dialect of Clojure that he has been developing for about eight years. Initially, jank was a personal exploration of his ideal programming language, informed by his experience in systems programming and game development with C++. His transition to using Clojure shaped the development direction of jank. The last two years of development have focused on establishing jank as a native Clojure dialect on LLVM, integrating the features of

This series of articles discusses the concept of Semigroups, focusing on the importance of associativity before delving into more complex applications. The author explores a practical example in their GitHub TUI project, where they manage rendering formatted strings to a terminal using an OCaml data type. The article highlights the challenges of terminal rendering, likening it to managing a mutable 2D array of bytes, and emphasizes the potential pitfalls of improper string concatenation, which could lead to incorrect output.

The content discusses the effectiveness of a data-oriented design pattern known as Struct of Arrays (SoA), specifically focusing on the potential benefits of using an Array of Enums (AoE). The key points are: 1. **Struct of Arrays (SoA)**: This pattern involves reorganizing data to improve performance, particularly when using SIMD (Single Instruction, Multiple Data) techniques. Instead of processing single items, it's more efficient to process multiple items simultaneously. 2. **SIMD Optimization**: An

The content emphasizes the importance of user feedback and outlines the features of a Ruby-based tool called Instruct, designed for interacting with Large Language Models (LLMs). Key points include: - **Ease of Use**: Instruct allows for intuitive manipulation of prompts and completions, similar to string manipulation, making it accessible for programmers. - **Dynamic Prompting**: It provides a helper (#p{}) for generating prompts with dynamic inputs, marking those inputs as unsafe for better security. - **Middleware Flex

OpenAI's new o3 system, trained on the ARC-AGI-1 Public Training set, achieved a significant score of 75.7% on the Semi-Private Evaluation set under a $10k compute limit, with a high-compute configuration scoring even higher at 87.5%. This marks a major advancement in AI capabilities, demonstrating unprecedented task adaptation typically not seen in GPT models. Over four years, the ARC-AGI-1 benchmark saw incremental improvements, suggesting that o

Bundler 2.6 has introduced gem checksum verification directly in the Gemfile.lock file, a feature that has been in development for over a year but was kept hidden until now. This new functionality aims to enhance security by ensuring that the gem files being installed match the checksums recorded in the lockfile, which helps prevent tampering. Users can enable this feature by either running `bundle lock --add-checkums` for a single lockfile or configuring Bundler to always include checksums with `

The quote by Henry David Thoreau highlights that being busy doesn’t equate to being productive or fulfilled. While some leaders seem unaffected by burnout, individual contributors (ICs) and middle managers frequently suffer from it. Preventing burnout requires identifying its true causes rather than resorting to vacations as a cure, as burnout often stems from a lack of purpose or agency rather than sheer workload. When individuals struggle to see how their work contributes to broader goals or lacks personal significance, they may feel unmotiv

Jeff Morhous discusses the challenges of deploying web applications and introduces Kamal, a new deployment tool in Rails 8 aimed at simplifying the process of shipping Docker-based apps without relying on traditional Platform-as-a-Service (PaaS) providers like Heroku. While deploying an application involves various infrastructure tasks such as server provisioning and scaling, PaaS platforms streamline these processes at a higher cost, potentially leading to situations where teams feel restricted by the services. Kamal offers a middle ground by providing flexibility

Over the past year, extensive work with various teams has shown that successful implementations of large language model (LLM) agents often rely on simple, composable patterns rather than complex frameworks. The term “agent” varies in definition; some see them as fully autonomous systems, while others consider them to be guided by predefined workflows. Anthropic categorizes all these variations as agentic systems but emphasizes the architectural distinction between workflows and agents. This post shares insights and practical advice on building effective agents by focusing on

The author reflects on a moment of surprise when a younger programmer expressed confusion about how a website could "erase" request history in Chrome's Network tab, not realizing the site was not a single-page application (SPA) and that each click fetched a new page without JavaScript. This encounter highlights a growing disconnect between the author’s understanding of programming and that of younger web developers. At 36 years old and programming since age 11, the author notes that many full-time developers started coding after their own
