The speaker addresses criticisms of Sorbet's syntax, acknowledging its verbosity and divergence from Ruby's style. They emphasize that, in programming, the semantics (meaning of types) are far more important than syntax. While the speaker recognizes the frustration with Sorbet's syntax, they believe many critics also have issues with static types in general, suggesting that changing their minds is unlikely. Instead, the talk is aimed at committed Sorbet users who appreciate its semantics but find the syntax challenging. The speaker encourages these users

The content discusses the Swift Container Plugin, which simplifies the process of building and publishing container images for Swift-based server applications using Swift Package Manager. Container images are essential for packaging cloud software, allowing deployment on various public or private cloud services or local execution with desktop container runtimes. The plugin enables users to package executable products defined in their Package.swift file into container images and publish them to a container registry. After integrating the plugin into a project, users can execute the build and publish process in a single step

Researchers from Lawrence Berkeley National Laboratory and international partners have made significant progress in converting carbon dioxide into liquid fuel using sunlight. They introduced a novel self-contained carbon-carbon (C2) producing system that utilizes copper catalysts and perovskite materials, similar to those in solar panels. This development is part of the Liquid Sunlight Alliance (LiSA), a collaborative research initiative funded by the U.S. Department of Energy and led by Caltech and Berkeley Lab. The project involves over 100 scientists working to

The author reflects on the nature of greatness in creativity, pondering the circumstances that shape influential artists, designers, and thinkers like Leonardo da Vinci, a representative of the "Renaissance Man." While da Vinci's extraordinary talent is often seen as a rare phenomenon, the author suggests that true creative ability may be more common than perceived, with recognition being the true rarity. In today's attention-driven society, where visibility equates to value, the metrics for judging design success can distort our understanding of greatness. The author

In 2017, Discord developed a message search system to index billions of messages using Elasticsearch, designed for performance, scalability, and cost-effectiveness. Messages were organized by Discord servers (guilds) or direct messages, allowing for efficient querying. A message queue facilitated lazy indexing, enabling bulk indexing to optimize performance. However, as Discord expanded, issues emerged, particularly with their Redis-backed real-time message indexing queue. When indexing delays occurred, often due to Elasticsearch node failures, the Redis system struggled under

The text highlights the importance of user feedback and introduces Sandbox MCP, a Model Context Protocol server designed for Large Language Models (LLMs) to run code safely in isolated Docker containers. While LLMs can generate code, they often cannot execute it, which can lead to issues when run on local machines. Sandbox MCP provides a secure environment for testing code, enabling more accurate coding with fewer errors. The system is inspired by Codapi, allowing users to create and configure their execution environments easily. A

The content discusses the challenges faced by two companies in the finance sector regarding PDF document generation using outdated technology. One company struggled to transition from an on-premise legacy system to a new cloud-based solution on AWS Lambda, initially promised to offer "infinite scaling." However, after six months and significant engineering resources, the legacy system remained in use due to inefficiencies in the new implementation. The author, motivated by these inefficiencies, developed a cost-effective and high-performance PDF rendering pipeline using a tech stack

The author discusses their experiences with open source software licenses, particularly the GNU General Public License (GPL), which they find resonates well with the principles of open source. They note that while GPLv3 is the latest version, GPLv2 is still commonly encountered. The author is intrigued by the physical address included in the GPLv2 license notice instead of a URL, questioning its relevance given the prevalence of the internet today. They learn that this is due to the fact that GPLv2 was published in

eserde is a new Rust crate developed by Mainmatter, built on top of the existing serde library, aimed at improving error reporting during the deserialization of user-facing payloads, such as API request bodies and configuration files. While serde typically halts deserialization upon encountering the first error, this can lead to a frustrating user experience, as multiple issues in a payload go unreported, necessitating multiple API interactions for resolution. eserde addresses this issue by reporting all schema violations at once, enabling developers

TinyWeb is a lightweight toolkit for building web applications using Rust on the client side. It consists of less than 800 lines of code with no external dependencies, focusing on simplicity and correctness. The framework allows developers to create client-side applications in pure Rust, similar to backend development, leveraging Rust’s strict type system and built-in tooling. To create a new project, users can initialize it with cargo and configure the project to use TinyWeb. Each TinyWeb project includes an `index.html`, a static

The article discusses the performance issues associated with counting rows in a PostgreSQL database. It explains that queries for counting rows often utilize a Sequential scan, which can be slow, and it raises the question of why PostgreSQL does not maintain a simple metadata count or use indexed leaf nodes for this purpose. To answer this, the article introduces Multi-Version Concurrency Control (MVCC), a system PostgreSQL employs to manage concurrent data access without traditional locks. MVCC allows for multiple versions of data (or
