The company is developing a public cloud using its own hardware and has invested in GPU technology for customer applications involving AI/ML inference. They created Fly GPU Machines, which are virtualized Docker/OCI containers equipped with Nvidia GPUs to perform fast CUDA operations. Despite recognizing the growing importance of AI/ML, the company feels their GPU product may not be meeting current market needs. They assure users that Fly GPU Machines will continue to be available, but major updates to the product are not imminent. Additionally, the

In this piece, Marcin Wichary reflects on his evolving relationship with typography, particularly focusing on the font Gorton. Initially, during his first trip to New York City in 2007, Wichary documented iconic fonts like American Typewriter and Helvetica, but overlooked Gorton, which is ubiquitous yet unremarkable in appearance. It wasn't until 2017, while researching for a book on the history of typing, that he discovered Gorton’s peculiar characteristics. He describes the font as

The Crunchy Data Warehouse is a next-generation, Postgres-native data warehouse that offers enhanced capabilities for handling event data from various devices. While PostgreSQL effectively manages individual and batch event data, it faces limitations for certain scenarios that require more efficient analysis, such as automated archival to cost-effective storage in a format conducive to large-scale analytical queries. To address these limitations, two open-source PostgreSQL extensions, pg_parquet and pg_incremental, have been developed. These enable the automatic export of specified time

Terrateam appreciates Fly.io for its efficient service, allowing simple deployment via a TOML file. Fly.io invests in server-side SQLite and has shared various blog posts about advancements in this area, including the introduction of Litestream for SQLite replication and LiteFS, a FUSE file system for replicating SQLite transactions. There is ongoing debate about using SQLite server-side; while it can function adequately, the SQLite project emphasizes its purpose as an ad-hoc application data file rather than a client/server database

The project described is called "emjay," a simple programming language implemented in Rust, featuring a Just-In-Time (JIT) compiler without a traditional interpreter. Emjay functions as a basic calculator, intentionally designed to be limited for easier end-to-end implementation. The code, which includes tests, is approximately 4,000 lines long and is available on GitHub. The project utilizes the pest parser library for parsing while other components of the compiler were hand-coded, leading to the generation of basic machine

Mathematicians have recently demonstrated that any sofa larger than a specific size will become stuck when moving through a hallway corner, which presents a complex geometric problem known as the "moving sofa problem." This issue, first framed by Leo Moser in 1966, involves determining the maximum area of a two-dimensional shape that can navigate through an L-shaped hallway of unit width without getting stuck at the corner. While smaller shapes like a square or semicircle can easily maneuver through, larger, more complex shapes

BetterHTMLChunking is a Python library designed for intelligent HTML segmentation that constructs a DOM tree from raw HTML to extract content-rich areas effectively. It is particularly useful for content analysis and large language model (LLM) processing. The library generates structured, size-limited segments from HTML documents while maintaining semantic coherence and respecting size constraints. Unlike plain-text or token-based chunking strategies which focus on token limits, BetterHTMLChunking preserves the HTML DOM structure, optimizing chunk boundaries based on the length of text

The task is to implement a Questionnaire feature in an app, utilizing a JSON column for flexible data storage. Initially, the Active Record store method is used to add accessors and ensure the data is tracked. However, after deployment, issues arise when the data team reports invalid JSON in the questionnaire table. Upon investigation, it's discovered Rails defaults to YAML for data serialization, leading to improperly formatted data in the database. To resolve this, the coder option is added to the store method, but it still

In Zig, you cannot perform a switch statement on strings (i.e., slices of bytes), which leads to an error message indicating that switching on strings is not allowed. There are two main reasons for this limitation: the ambiguity surrounding string identity (whether equal strings need to point to the same address, and how null-terminated vs. non-null-terminated strings are treated), and the expectations of users for certain optimizations that are not feasible with strings. Instead, string comparison in Zig is typically done

Subscribing to LWN provides support for ongoing publishing and grants subscribers immediate access to all site content and additional features. Jake Hillion recently presented at FOSDEM on using the BPF scheduling framework, specifically sched_ext from kernel version 6.12, to identify difficult concurrency issues. He, alongside Johannes Bechberger, developed a scheduler that effectively exposes theoretically possible concurrency bugs in Linux applications, though the project is still in early stages.

The author shares their experience working on a legacy project, emphasizing the challenges and frustrations often associated with such work. Despite their dislike for legacy projects, they gained insights into modern practices and were part of a team that generally follows best practices. While there were some inefficiencies, such as trivial pull requests and issues with the operations team, the overall team performance was good. However, their team was directed to assist another project that used an outdated version of Java and older coding standards, which added to their reluct

The project involves a virtual petri dish where digital creatures evolve eyes over millions of simulated years, beginning with a simple light-detecting cell. These creatures face various challenges that mirror those encountered in nature, such as finding food, avoiding toxins, and evading predators. As a result, they develop different types of eyes—like compound eyes for navigation and camera-like eyes for distinguishing food from poison—demonstrating the emergence of solutions similar to those found in natural evolution, including the development of lenses

On February 13, 2025, Kagi Search announced the introduction of a new privacy feature called Privacy Pass, which is an authentication protocol intended to enhance user privacy. Privacy Pass enables clients (users) to authenticate with servers (like Kagi) without the server being able to identify individual users, thus protecting user privacy while granting access to services. This aligns with Kagi's commitment as a privacy-focused search engine, which does not track users or sell their data. The implementation of Privacy Pass
