This GitHub project, titled "Hobby Project: A dynamic C (Hot reloading) module-based Web Framework," details the development of a web framework written entirely in C, with a focus on dynamic module loading and hot reloading capabilities. The author's primary goal is to create a system where modifying and recompiling individual modules doesn't necessitate restarting the entire web server, thereby significantly streamlining the development workflow. This is achieved through a modular architecture where functionality is broken down into separate, dynamically linked libraries (.so files on Linux/macOS, .dll files on Windows).
The framework utilizes a central core responsible for handling incoming HTTP requests and routing them to the appropriate modules. These modules, compiled as shared libraries, can be loaded, unloaded, and reloaded at runtime without interrupting the server's operation. This dynamic loading is facilitated through the use of dlopen and related functions (or their Windows equivalents). When a module is modified and recompiled, the framework detects the change and automatically reloads the updated library, making the new code immediately active.
The project utilizes a custom configuration file, likely in a format like JSON or INI, to define routes and associate them with specific modules and their respective functions. This allows for flexible mapping of URLs to specific functionalities provided by the loaded modules.
The hot reloading mechanism likely involves some form of file system monitoring to detect changes in module files. Upon detection of a change, the framework gracefully unloads the old module, loads the newly compiled version, and updates the routing table accordingly. This process minimizes downtime and allows for continuous development and testing without restarting the server.
While the project is explicitly labelled as a hobby project, suggesting it isn't intended for production use, it explores an interesting approach to web framework design in C. The focus on modularity and dynamic reloading offers potential advantages in terms of development speed and flexibility. The implementation details provided in the repository offer insights into the challenges and considerations involved in building such a system in C, including memory management, inter-module communication, and handling potential errors during dynamic loading and unloading.

NVIDIA has introduced Garak, a novel open-source tool specifically designed to rigorously assess the security vulnerabilities of Large Language Models (LLMs). Garak operates by systematically generating a diverse and extensive array of adversarial prompts, meticulously crafted to exploit potential weaknesses within these models. These prompts are then fed into the target LLM, and the resulting output is meticulously analyzed for a range of problematic behaviors.
Garak's focus extends beyond simple prompt injection attacks. It aims to uncover a broad spectrum of vulnerabilities, including but not limited to jailbreaking (circumventing safety guidelines), prompt leaking (inadvertently revealing sensitive information from the training data), and generating biased or harmful content. The tool facilitates a deeper understanding of the security landscape of LLMs by providing researchers and developers with a robust framework for identifying and mitigating these risks.
Garak's architecture emphasizes flexibility and extensibility. It employs a modular design that allows users to easily integrate custom prompt generation strategies, vulnerability detectors, and output analyzers. This modularity allows researchers to tailor Garak to their specific needs and investigate specific types of vulnerabilities. The tool also incorporates various pre-built modules and templates, providing a readily available starting point for evaluating LLMs. This includes a collection of known adversarial prompts and detectors for common vulnerabilities, simplifying the initial setup and usage of the tool.
Furthermore, Garak offers robust reporting capabilities, providing detailed logs and summaries of the testing process. This documentation helps in understanding the identified vulnerabilities, the prompts that triggered them, and the LLM's responses. This comprehensive reporting aids in the analysis and interpretation of the test results, enabling more effective remediation efforts. By offering a systematic and thorough approach to LLM vulnerability scanning, Garak empowers developers to build more secure and robust language models. It represents a significant step towards strengthening the security posture of LLMs in the face of increasingly sophisticated adversarial attacks.
The Hacker News post for "Garak, LLM Vulnerability Scanner" sparked a fairly active discussion with a variety of viewpoints on the tool and its implications.
Several commenters expressed skepticism about the practical usefulness of Garak, particularly in its current early stage. One commenter questioned whether the provided examples of vulnerabilities were truly exploitable, suggesting they were more akin to "jailbreaks" that rely on clever prompting rather than representing genuine security risks. They argued that focusing on such prompts distracts from real vulnerabilities, like data leakage or biased outputs. This sentiment was echoed by another commenter who emphasized that the primary concern with LLMs isn't malicious code execution but rather undesirable outputs like harmful content. They suggested current efforts are akin to "penetration testing a calculator" and miss the larger point of LLM safety.
Others discussed the broader context of LLM security. One commenter highlighted the challenge of defining "vulnerability" in the context of LLMs, as it differs significantly from traditional software. They suggested the focus should be on aligning LLM behavior with human values and intentions, rather than solely on preventing specific prompt injections. Another discussion thread explored the analogy between LLMs and social engineering, with one commenter arguing that LLMs are inherently susceptible to manipulation due to their reliance on statistical patterns, making robust defense against prompt injection difficult.
Some commenters focused on the technical aspects of Garak and LLM vulnerabilities. One suggested incorporating techniques from fuzzing and symbolic execution to improve the tool's ability to discover vulnerabilities. Another discussed the difficulty of distinguishing between genuine vulnerabilities and intentional features, using the example of asking an LLM to generate offensive content.
There was also some discussion about the potential misuse of tools like Garak. One commenter expressed concern that publicly releasing such a tool could enable malicious actors to exploit LLMs more easily. Another countered this by arguing that open-sourcing security tools allows for faster identification and patching of vulnerabilities.
Finally, a few commenters offered more practical suggestions. One suggested using Garak to create a "robustness score" for LLMs, which could help users choose models that are less susceptible to manipulation. Another pointed out the potential use of Garak in red teaming exercises.
In summary, the comments reflected a wide range of opinions and perspectives on Garak and LLM security, from skepticism about the tool's practical value to discussions of broader ethical and technical challenges. The most compelling comments highlighted the difficulty of defining and addressing LLM vulnerabilities, the need for a shift in focus from prompt injection to broader alignment concerns, and the potential benefits and risks of open-sourcing LLM security tools.
The Hacker News post introduces Zyme, a novel programming language designed with evolvability as its core principle. Zyme aims to facilitate the automatic creation and refinement of programs through evolutionary computation techniques, mimicking the process of natural selection. Instead of relying on traditional programming paradigms, Zyme utilizes a tree-based representation of code, where programs are structured as hierarchical expressions. This tree structure allows for easy manipulation and modification, making it suitable for evolutionary algorithms that operate by mutating and recombining code fragments.
The language itself is described as minimalistic, featuring a small set of primitive operations that can be combined to express complex computations. This minimalist approach reduces the search space for evolutionary algorithms, making the process of finding effective programs more efficient. The core primitives include arithmetic operations, conditional logic, and functions for manipulating the program's own tree structure, enabling self-modification. This latter feature is particularly important for evolvability, as it allows programs to adapt their own structure and behavior during the evolutionary process.
Zyme provides an interactive environment for experimentation and development. Users can define a desired behavior or task, and then employ evolutionary algorithms to automatically generate programs that exhibit that behavior. The fitness of a program is evaluated based on how well it matches the specified target behavior. Over successive generations, the population of programs evolves, with fitter individuals being more likely to reproduce and contribute to the next generation. This iterative process leads to the emergence of increasingly complex and sophisticated programs capable of solving the given task.
The post emphasizes Zyme's potential for exploring emergent behavior and solving complex problems in novel ways. By leveraging the power of evolution, Zyme offers a different approach to programming, shifting the focus from manual code creation to the design of evolutionary processes that can automatically discover efficient and effective solutions. The website includes examples and demonstrations of Zyme's capabilities, showcasing its ability to evolve programs for tasks like image processing and game playing. It also provides resources for learning the language and contributing to its development, suggesting a focus on community involvement in shaping Zyme's future.
The Hacker News post "Show HN: Zyme – An Evolvable Programming Language" sparked a discussion with several interesting comments.
Several commenters express interest in the project and its potential.

Another commenter draws a parallel between Zyme and Wolfram Language, highlighting the shared concept of symbolic programming, but also questioning Zyme's unique contribution. This commenter seems intrigued but also cautious, prompting a need for clearer differentiation and practical examples. A different commenter focuses on the aspect of "evolvability" being central to genetic programming, subtly suggesting that the project description might benefit from emphasizing this aspect more prominently.
One commenter expresses skepticism about the feasibility of using genetic programming to solve complex problems, pointing out the challenges of defining effective fitness functions. They allude to the common issue in genetic programming where generated solutions might achieve high fitness scores in contrived examples but fail to generalize to real-world scenarios.
Furthering the discussion on practical applications, one commenter questions the current state of usability of Zyme for solving real-world problems. They express a desire to see concrete examples or success stories that would showcase the language's practical capabilities. This comment highlights a general interest in understanding how Zyme could be used beyond theoretical or academic contexts.
Another commenter requests clarification about how Zyme handles the issue of program bloat, a common problem in genetic programming where evolved programs can become excessively large and inefficient. This technical question demonstrates a deeper engagement with the technical aspects of Zyme and the challenges inherent in genetic programming.
Overall, the comments reveal a mix of curiosity, skepticism, and a desire for more concrete examples and clarification on Zyme's capabilities and differentiation.
