Niri is a new programming language designed for building distributed systems. It aims to simplify concurrent and parallel programming by introducing the concept of "isolated objects" which communicate via explicit message passing, eliminating shared mutable state and thus avoiding data races and other concurrency bugs. This approach, coupled with automatic memory management and a focus on performance, makes Niri suitable for developing robust and efficient distributed applications, potentially replacing complex actor models or other concurrency paradigms. The language is still under development, but shows promise for streamlining the creation of complex distributed systems.
The blog post "The Future Is Niri" by Alexej Diez introduces Niri, a novel programming language designed to address the limitations of existing languages, particularly regarding concurrency and memory management. Diez posits that the current landscape of programming languages, while offering a variety of paradigms and tools, struggles to adequately manage the increasing complexities of modern hardware and software architectures, especially in the realm of parallel and distributed computing. He argues that prevalent approaches to concurrency, like shared memory with mutexes or message passing, are inherently prone to errors and difficult to reason about, leading to significant development overhead and susceptibility to subtle bugs.
Niri, as Diez elaborates, aims to overcome these challenges by introducing a fundamentally different model centered around the concept of isolated state, inspired by the actor model and offering a "shared nothing" concurrency paradigm. Each computational unit in Niri operates within its own isolated state, precluding shared mutable state and thus eliminating data races and other concurrency-related issues. Communication between these isolated units is achieved through asynchronous message passing, ensuring a deterministic and predictable execution flow, irrespective of the underlying hardware architecture or the number of concurrent operations.
The post delves into the specifics of Niri's syntax and semantics, highlighting its focus on simplicity and clarity. It emphasizes a type system designed for both safety and performance, allowing for compile-time detection of various errors and enabling efficient code generation. Diez further explains the memory management model of Niri, which leverages a combination of automatic memory management, employing techniques akin to garbage collection, along with explicit memory allocation control for fine-grained optimization when necessary. This dual approach provides the convenience of automated memory management without sacrificing the potential for performance optimization in critical sections of code.
Furthermore, the post underscores the potential of Niri to facilitate the development of robust and scalable distributed systems. By inherent design, Niri's isolation model and asynchronous communication primitives naturally align with the requirements of distributed computing, simplifying the process of designing and implementing complex distributed applications. Diez concludes by expressing his belief that Niri represents a significant step towards a future where concurrent and distributed programming is significantly more accessible and less error-prone, ultimately leading to more robust and performant software systems. He anticipates that Niri’s unique features will pave the way for innovation in various domains, particularly those demanding high concurrency and reliability.

Hacker News users discussed Niri's potential, focusing on its novel approach to UI design. Several commenters expressed excitement about the demo, praising its speed and the innovative concept of manipulating data directly within the interface. Concerns were raised about the practicality of text-based interaction for complex tasks and the potential learning curve. Some questioned the long-term viability of relying solely on a keyboard-driven interface, while others saw it as a powerful tool for experienced users. The discussion also touched upon comparisons to other tools like spreadsheets and the potential benefits for specific use cases like data analysis and programming. Some users expressed skepticism, finding the current implementation limited and wanting to see more concrete examples of its capabilities.
The Hacker News post "The Future Is Niri," linking to an article describing a hypothetical new internet protocol called Niri, generated several comments discussing its feasibility, potential benefits, and drawbacks.
Several commenters expressed skepticism about Niri's claims and its ability to overcome existing internet infrastructure challenges. One commenter questioned the practicality of Niri's micropayment system for content retrieval, highlighting the existing complexities and costs associated with micropayment infrastructure. They also pointed out the potential for abuse and the difficulty in determining fair pricing for various types of content. Another skeptic argued that the benefits of Niri, such as censorship resistance and improved efficiency, are overstated and that similar functionalities are already achievable or in development within existing protocols. The commenter also raised concerns about the cost and complexity of transitioning to a new internet architecture.
A recurring theme in the comments was the difficulty of replacing the existing internet infrastructure. Commenters pointed out the entrenched nature of TCP/IP and the massive undertaking required to transition to a new protocol. They also questioned the economic incentives for such a shift, given the significant investments already made in current technologies. One commenter drew parallels with previous attempts to create alternative internet architectures, suggesting that Niri might face similar challenges in gaining widespread adoption.
Despite the skepticism, some commenters expressed interest in Niri's potential. One commenter praised the innovative approach and the focus on addressing some of the internet's limitations, particularly in the areas of security and efficiency. They acknowledged the significant hurdles to implementation but encouraged further exploration of the concept. Another commenter specifically highlighted the potential of Niri's addressing system to improve routing efficiency and reduce latency.
The discussion also touched upon the technical aspects of Niri, with some commenters questioning the specifics of its implementation and its ability to scale to the size of the current internet. One commenter raised concerns about the potential for denial-of-service attacks and the need for robust mechanisms to mitigate such threats.
Overall, the comments on the Hacker News post reflect a mix of skepticism and cautious optimism towards Niri. While some commenters see potential in its innovative approach, others remain unconvinced of its practicality and ability to overcome the significant challenges associated with replacing the existing internet infrastructure. The discussion highlights the complex considerations involved in developing and deploying a new internet protocol and the importance of addressing issues such as scalability, security, and economic incentives.
