In a previous post, the author discussed issues with long-running queries in a production incident involving PostgreSQL, where queries were hanging, IOPS were maxed out, and connections needed to be manually killed. The root cause was identified as poor indexing, which led to unnecessary data retrieval from disk. Although that issue was resolved with better indexes, the author remained puzzled about why the system didn't recover automatically after hitting 3000 IOPS. The post explores the inner workings of PostgreSQL's I/O subsystem

On February 13, 2026, the author engaged Claude Code by providing it access to a pen plotter via an intermediary interface. Claude Code generated SVG files that were plotted, while the author captured photos to input back into the session for discussion. Claude produced and signed two drawings and wrote a post reflecting on what it learned. The session began with the author prompting Claude to think deeply about its identity, capabilities, and feelings before creating a drawing. Claude described itself as a process of structured computation

The content discusses PyTorch, a popular deep learning framework developed by Meta AI and now part of the Linux Foundation. It highlights the significance of tensors in machine learning, explaining that tensors are specialized data types used to store numerical data, akin to enhanced lists or arrays. Tensors hold training data and model weights, which determine the importance of inputs for model decisions. The document outlines various tensor initialization functions in PyTorch, such as torch.rand(), torch.randn(), torch.ones(), and torch.empty(). Each function

A recent study by researchers at Iceberg Quantum introduced a new quantum computing architecture called the "Pinnacle Architecture," which could factor a 2048-bit RSA integer using fewer than 100,000 physical qubits. This estimate is significantly lower than previous predictions, which suggested that over one million qubits would be necessary under similar error conditions. The architecture uses quantum low-density parity-check (QLDPC) codes instead of traditional surface codes, potentially allowing for more efficient error correction. The researchers state

The author expresses frustration with the hype around "brain-inspired AI" and "neuromorphic computing," emphasizing that despite being a fascinating academic concept, its practical applications in enterprise software are limited, especially outside of specific use cases like edge devices. They critique the disconnect between the promised paradigm shift and the reality, noting that neuromorphic computing primarily serves as a specialized accelerator for specialized problems that could be solved more efficiently with traditional GPUs. The technology aims to mimic the brain's energy-efficient, event-driven processing

Spotify has embraced AI in its coding processes, reaching a significant milestone where top developers haven't written code since December, according to co-CEO Gustav Söderström. The company reported launching over 50 new features and updates in its app throughout 2025, showcasing its reliance on AI to enhance development speed. They utilize an internal system named "Honk," which employs generative AI—specifically Claude Code—for efficient coding, allowing engineers to deploy changes remotely and in real-time. For instance, developers

The content discusses the challenges faced by a startup in managing its codebase. The author outlines various issues they've encountered and their approach to resolving them. Key points include the transition from an old method of defining class properties to using modern practices like constructor promotion and readonly classes, which were initially chosen for simplicity and familiarity with older PHP versions. The author also reflects on a previous usage of Enums that was not aligned with the Domain-Driven Design (DDD) architecture, prompting a need to reorganize them into

The content emphasizes the importance of user feedback and reassures that it is taken seriously. It references the DCIEM decompression model programs from a 1973 report, highlighting that the code is a faithful recreation of the original programs for research purposes. However, it notes that this code has not been validated for real-world diving or life-support decisions, and users should not rely on it for planning dives. Additionally, there is a mention of a loading error that prompts users to reload the page.

The author reflects on their concept of "Company as Code," which emerged from frustration during an information security compliance audit. They wondered why proving compliance in a software environment wasn't more automated, given that data is readily available on SaaS platforms. Inspired by Terraform, which allows for infrastructure management through a declarative language, the author sought to create a similar system for business data—enabling structured, accessible representations of a business to facilitate audits and more. In 2025, the author founded 42f

An allocator is a tool used in programming to reserve memory, typically on the heap, for storing data structures. While many C programs utilize the standard libc allocator, modern systems languages treat allocators as first-class citizens. This document discusses how various languages—including Rust—handle memory allocation and presents an approach for creating an allocator in C. Rust uses a global memory allocator that is employed by constructs like Box<T> and Vec<T>. Although it currently has an unspecified default global allocator, it typically relies on the

The author is experimenting with how Google interprets their website as it shifts from traditional search to AI chatbots. They added JSON-LD structured data to improve Google's ability to scrape their site's information. The tests revealed that Google correctly read their pricing table but later presented a note indicating the site was offline as of early 2026. The author questions the validity of this note, highlighting several points: the site is operated on a reliable Cloudflare service, Google likely can't detect site status behind a login wall

The text compares the landscape of AI research to Star Wars, with OpenAI as the "Death Star" and innovative startups as "rebels." These startups are creating impressive audio models, such as text-to-speech (TTS) and speech-to-text (STT), often outperforming larger labs despite having limited resources. One notable startup, Gradium, emerged from the open lab Kyutai. In summer 2024, a Kyutai researcher named Neil showcased an advanced audio AI model

In the macOS 26.3 RC release notes, Apple announced a fix for a window-resizing issue previously highlighted in a blog post. In response, the author created a test app to analyze the changes. The app conducts a pixel-by-pixel scan around the bottom-right corner of the window to identify responsiveness to mouse clicks. The results showed that the new resizing areas now match the window's corner radius, a positive improvement. However, the resizing zone for vertical and horizontal adjustments was reduced in
