In a recent conversation, an engineer and I discussed "shitty code," prompting me to share my inspiration, Flamework, a pseudo framework created at Flickr. My work is driven by two main passions: creating elegant, reusable code for Open Source projects and building quick, pragmatic solutions for end users, often in product development where speed is vital. I have learned that the aims of creating reusable code and solving user problems can conflict. This realization began during my work on the German ubuntuusers website,

The article, authored by Stephan Ewen, Ahmed Farghal, and Till Rohrmann, provides an in-depth exploration of Restate, a Durable Execution engine designed without reliance on databases or logging systems. This post is the second in a series discussing the development of a durable execution system based on fundamental principles. The previous article, "Every System is a Log," highlighted the advantages of a unified log architecture for simplifying distributed coordination. In this installment, the authors describe the design of the log-based runtime

In the episode of the Maintainable Software Podcast, Marty Haught discusses the sustainability of open-source projects and the challenges surrounding RubyGems, proposing the concept of "drift" instead of "technical debt" to describe how software can become misaligned with its intended purpose over time. The conversation also addresses security issues in package management, highlighting a collaboration between Ruby Central and Trail of Bits to audit RubyGems. They touch on the potential impacts of the EU Cyber Resilience Act on open-source maintain

The author has adopted a new methodology called "append-only programming," which emphasizes defining interfaces before implementations, promoting the writing of small functions, and enhancing code readability. This approach mimics a stream-of-consciousness style, but it comes with challenges: correcting errors requires appending new functions and possibly retyping entire programs. The author prefers using a shell command to write code, which enforces the append-only rules. While the concept is framed as a fun challenge rather than a practical programming method, it highlights

The Brazilian Navy has confirmed the location of the shipwreck of the Vital de Oliveira, which sank 28 miles off the coast of Rio de Janeiro after being torpedoed by a German U-boat on June 19, 1944. The ship was transporting supplies and soldiers during World War II and was the Brazilian Navy's greatest loss, with 99 of the 270 individuals aboard perishing. The wreck, first reported 14 years ago, was identified using advanced sonar technology. Brazil was

In the scenario, a king or queen faces a dilemma when attempting to communicate new laws to their subjects amid a flooding issue that blocks road access to some cities. Understanding the importance of everyone being aware of the laws to ensure justice, the ruler sends messengers with tablets containing the laws. However, the flood prevents full delivery, leading to a decision point influenced by the CAP theorem from network theory, which discusses the trade-off between consistency and availability in decentralized systems. Consistency is likened to ensuring all

The content discusses the author's experience with creating "Choose Your Own Adventure" style stories using various large language models (LLMs). These interactive stories allow readers to make choices that influence the narrative. The generation process starts with Title Generation based on user-selected prompts, followed by Narrative Generation, where the LLM creates the story's text creatively. For Image Generation, a specific formatted prompt for a Stable Diffusion model is created from the narrative, rather than directly using the narrative itself. The process for generating

The content describes the Magma pretraining pipeline, which involves tokenizing texts and encoding images and videos through a shared vision encoder. This process results in discrete and continuous tokens that are input into a large language model (LLM) for generating outputs related to verbal, spatial, and action types. Two key prompting methods are introduced: 1. **Set-of-Mark (SoM)** – This method aids action grounding in images across various applications, helping the model identify clickable UI buttons or robot arms by

In this post, the author discusses the integration of previously covered concepts related to the SQLite file format and a basic SQL parser to create a query evaluator, focusing on handling basic SELECT statements. The evaluator won't yet include features such as filtering, sorting, grouping, or joins, but will serve as a foundation for future enhancements. To begin evaluating queries, the author suggests creating a simple database with a single table (table1) containing two columns: id and value. A caution is provided against using existing

The content discusses the feasibility of writing functional code solely using the `#define` directive in C, drawing a comparison to C++ templates, which are Turing complete. It hints at the complexity of the question and introduces a personal project: a simple compiler for a newly invented language named "wend." The author seeks to create engaging and illustrative examples, avoiding conventional examples like Fibonacci calculations. Instead, they aim to create a bonfire animation using terminal escape sequences for output. The author plans to first implement

The author introduces a series of articles aimed at those curious about how compilers work. Motivated by personal interest, the author created a simple programming language called "wend" (short for weekend) and wrote a translator that compiles wend code into GNU assembly. The goal is to produce a minimal compiler in about 500 lines of Python. The author notes that wend is a basic, strongly typed language similar to C or Java, but lacking features like pointers, arrays, and dynamic memory.

The author notes that there will be no newsletter next week due to teaching a TLA+ workshop and reflects on their focus on formal methods (FM) and TLA+ as their primary revenue source. They express that while most readers may not engage with FM, they prefer to share ideas that are relevant across different fields. One concept discussed is "property strength," which relates to the varying strength of tests. The author explores the theme of nondeterminism in system modeling, categorizing it into five types

The article by Adam McCrea addresses the "ConnectionTimeoutError" that often occurs in Ruby on Rails applications, specifically when the application cannot obtain a database connection from the pool in a specified time. This error arises not from the database itself, but from insufficient configuration of the connection pool within Rails. Each Rails process maintains a pool of database connections to support multiple threads, preventing contention for a single connection. To resolve the error, one typically needs to increase the connection pool size, which is set

In system design, achieving perfect consistency, availability, latency, and throughput simultaneously is challenging, if not impossible. Instead, each property should be balanced to find the appropriate fit for the application. The author discusses recent trade-offs made in the design of Bluesky's Following Feed/Timeline to enhance write performance, resulting in a significant reduction in latency while maintaining a user-friendly experience. When a user posts, it is indexed and stored in a database, and a reference is sent to their followers' Timelines

The `dependent: :restrict_with_error` option in Rails is an effective way to maintain data integrity by preventing the deletion of parent records that have existing associated records. This feature not only preserves historical data but also provides users with clear error messages regarding dependency management. When utilizing associations in Rails, it’s crucial to manage referential integrity. The `dependent: :restrict_with_error` option ensures that records cannot be deleted until their dependencies are adequately addressed, unlike alternatives such as `:destroy`, `
