The recent dispute between David Heinemeier Hansson (DHH), creator of Ruby on Rails, and Matt Mullenweg, founder of WordPress, has reignited discussions on open source sustainability. DHH launched a kanban tool called Fizzy, labeled as open source, but critics highlighted that its O'Saasy license prevents the development of competing SaaS versions, which contradicts the Open Source Initiative's definition. DHH dismissed these concerns, while Mullenweg argued that ignoring the established

This paper presents a novel method for removing transformers from inference processes while maintaining or enhancing downstream accuracy. It demonstrates that a 70-billion-parameter Llama-3.3-70B model can be substituted with a 256-dimensional meaning field derived from its internal activation layers. The method utilizes a lightweight compressor (AN1), achieving a 224× reduction in size and a +1.81 percentage point increase in accuracy across classification tasks, with a notable +3.25 pp improvement on low-resource

The passage discusses a common issue in C++ programming related to move semantics and exception safety, particularly when using `std::vector`. It explains that if a type's move constructor is not marked with the `noexcept` keyword, the compiler opts to perform copying instead of moving during operations like vector reallocation, which can lead to performance inefficiencies. This precaution is taken to ensure the "strong exception guarantee," meaning that if an exception occurs during reallocation, the original vector remains intact. The text

Django 6.0 has been released, marking a new cycle for the popular Python web framework, which is now 20 years old. The release includes various new features, some of which the author contributed to. A tool called django-upgrade is available for users upgrading from Django 5.2 or earlier, which helps automatically update code and address deprecation warnings. The major highlight of this release is the introduction of "partials," defined by the new `{% partialdef %}` and `{

The author discusses a specific hash table design known as Robin Hood open-addressing using linear probing and a power-of-two table size. The design integrates several properties for efficiency: each table slot can either be empty or hold a key/value pair stored as a 64-bit integer, where the low 32 bits represent the key and the high 32 bits represent the value. This allows for the use of the value 0 to denote an empty slot, eliminating the need for special values for tombstones.

The post discusses the use of the `auto` keyword in C++ for type deduction, presenting a series of coding examples for readers to determine the deduced types. Readers are encouraged to identify cases where the code might not compile, and the examples increase in complexity. Topics covered include basic assignments, handling of references and CV-qualifiers, advanced concepts like forwarding references and lambda expressions, and the challenges of type deduction with lambda captures and structured binding. The author provides resources for further exploration, invites readers

Stephen Ramsay expresses his passion for programming and his disdain for "vibe coding," which he feels detracts from the joy and satisfaction of the coding process. He reflects on his two-decade teaching career, emphasizing his pride in transforming non-programmers into programmers. Ramsay likens programming to solving a complex crossword puzzle that brings joy when completed, but feels that vibe coding diminishes that experience, making him feel as though he hasn't truly accomplished anything. He acknowledges the challenges of understanding programming at a

Fresh utilizes a piece tree, or piece table, for text storage, a concept developed in the early 1970s by J. Strother Moore and Bob Boyer in their "77-Editor." This method focuses on structure-sharing to optimize text editing without modifying original files, which was crucial for early systems with limited RAM. Charles Simonyi later adapted the idea at Xerox PARC for the Bravo editor and subsequently for Microsoft Word. In 2018, VS Code implemented piece tables to replace

The content discusses the importance of gamification, particularly through badge systems, in enhancing user engagement across various platforms like learning, fitness, and productivity applications. The series starts with the basics of implementing a simple badge system focused on recording accomplishments without unnecessary complexity. Initially, badges can be hardcoded into business logic, making implementation straightforward for early-stage products. However, as applications grow, this approach reveals limitations, leading to the need for progress tracking and dynamic badge management. The first major improvement involves supporting badges that

Bruno Simon, a creative developer specializing in web design, invites visitors to explore his portfolio in an interactive 3D environment. The server is currently offline, preventing score saving and the display of visitor messages, referred to as "whispers." Up to 30 messages can be left, but new ones replace old ones, and users can only submit one while adhering to a character limit and guidelines against inappropriate content. The portfolio utilizes Three.js, a library for 3D rendering, highlighting contributions from

The content discusses the Strangler Fig pattern, a method for incrementally migrating a legacy system to a new application by gradually replacing specific functionalities with new services. This approach allows the old system to be gradually suppressed and ultimately decommissioned, making the transition smoother for clients who can continue using the existing interface while the migration occurs. It addresses the challenges of maintaining two versions of an application and ensures minimal disruption by routing requests through a façade (proxy) that manages interactions between the new and old systems during modernization

In the article by Gregory Brown, the author discusses the challenges in implementing the Singleton design pattern in Ruby, noting that while many design patterns have elegant translations in Ruby, the Singleton pattern does not. The Singleton pattern is described as a means to create global objects that do not need explicit instantiation, typically used for single instances needed throughout an application, such as configuration data or logging systems. The author acknowledges that the Math module serves as an example of a singleton object in Ruby. Despite various methods available to

After two years of using the Shape-Up software development methodology, Customaite decided to discontinue it due to its rigid structure not aligning with their evolving needs. Although they were attracted to Shape-Up's promise of longer focus periods and value-based prioritization to address ongoing project challenges, they ultimately found that projects often extended beyond planned sprints, leading to an accumulation of work-in-progress. Shape-Up, created by Basecamp, is characterized by 6-week development cycles followed by 2-week cooldown periods,
