The content discusses Ruby's Fibers, which offer lightweight, cooperative concurrency distinct from threads, which are managed by the operating system. Fibers allow developers to control when execution pauses and resumes, functioning like pausable functions. They can share data during these pauses and are particularly useful for creating generators. The introduction of the Fiber Scheduler API in Ruby 3.0 enhances non-blocking I/O operations by enabling developers to write asynchronous code without callbacks, although no default scheduler is provided. Instead, developers must

After years as an ML engineer focused on Python's async features, returning to Ruby felt outdated due to its reliance on thread-based concurrency models, such as those in SolidQueue, Sidekiq, and GoodJob. This stood in stark contrast to Python's shift towards asyncio, which saw a complete transformation of its ecosystem. However, while developing RubyLLM and Chat with Work, the author identified that asynchronous communication in LLM applications highlighted the advantages of Ruby's async capabilities. They realized Ruby's approach

The article discusses the evolution of C++, highlighting its origins in the 1980s when classes were first introduced by Bjarne Stroustrup. It notes that the 'this' keyword, an indication of its early design as a pointer, supports the idea that classes were a foundational feature of the language. The piece reflects on C++'s development over the years, including the adoption of object-oriented programming (OOP), encapsulation, and inheritance as dominant paradigms. It also mentions

Arthur O’Dwyer discusses the origin of the term "calling" functions in programming, particularly in the context of C++. The term likely derives from the idea of "calling up" or "summoning" a subroutine, which relates to how one would "call for" a book from a closed-stack library. This usage is traced back to library terminology, with the Oxford English Dictionary (OED) citing its first library-related use in 1876 by Melvil Dewey. The

The content discusses the functionality and benefits of the garbage collector (GC) in the Common Language Runtime (CLR), which acts as an automatic memory manager for applications. It allows developers to avoid manual memory management tasks, reducing the risk of memory leaks and unsafe memory access. The GC efficiently allocates memory on the managed heap, reclaims unused objects, and ensures memory safety by preventing objects from using memory allocated for others. Additionally, it highlights key memory concepts, such as the separation of virtual address space for
