The Coder Cafe discusses Conflict-Free Replicated Data Types (CRDTs) and their importance in distributed systems, emphasizing their ability to facilitate independent updates across nodes while ensuring all replicas eventually reach the same state. CRDTs may seem complex initially, but the concept revolves around managing concurrent operations—actions that occur independently without knowledge of one another—by providing a framework that enables synchronization. The distinction between concurrent operations and conflicts is also addressed, illustrating that concurrent edits can occur without conflict, while conflicting edits

The Temporal Ruby SDK has reached General Availability (GA), enabling Ruby developers to build durable software with ease. This SDK is fully supported, offering the same features as other officially supported Temporal languages. The post provides a high-level overview of Temporal Ruby and dives into technical aspects, such as Rust integration, durable fiber implementation, and handling illegal calls. Temporal is a framework for creating deterministic code that can withstand crashes by recording actions as events, allowing it to resume from the last executed point. The Ruby SDK translates

The content discusses a tool called modshim, which allows users to enhance existing Python modules without modifying their original code. This approach serves as a cleaner alternative to forking or monkey-patching. Modshim creates a new "shimmed" module that combines original functionality with customized enhancements while keeping the original module intact. For instance, if you want to enhance the built-in `textwrap` module by adding a prefix to wrapped lines, you would create a new module that mirrors the original structure. You would

The article discusses two vulnerabilities found in NVIDIA's Linux Open GPU Kernel Modules, which can be exploited by attackers with access to local unprivileged processes. These bugs were identified in the nvidia.ko and nvidia-uvm.ko modules, which expose ioctls to unprivileged users. Although meant for NVIDIA's proprietary binaries, the header files allowed for direct ioctl calls, leading to the discovery of these vulnerabilities. One notable vulnerability involves the UVM_MAP_EXTERNAL_ALLOCATION ioctl,

The text discusses a recent refactoring of complex code related to customer and order management in an enterprise resource planning (ERP) system. The code refactoring aimed to simplify requests management by leveraging static analysis through applicative functors. These functors allow for a completely static control flow but have limitations in expressing computations that depend on previous results. The goal was to batch queries efficiently without dealing with data dependencies, enabling library users to benefit from batch query APIs without managing batching details. The article also introduces the “

The author recounts a near-miss with a sophisticated scam while preparing for a coding interview with a seemingly legitimate blockchain company, Symfa, through its Chief Blockchain Officer, Mykola Yanchii. After receiving a "test project" consisting of a React/Node codebase, the author, who usually practices good security habits, rushed through the initial code review without running it in a safe environment. At the last moment, they decided to consult an AI tool to check for suspicious code. This

The post summarizes chapter 5 of Sebastian Raschka's book "Build a Large Language Model (from Scratch)," focusing on the challenges of understanding cross-entropy loss and perplexity. It highlights that, despite the chapter being shorter than previous ones, it is particularly exciting as it culminates in a functioning codebase for training a language model. The author successfully trained their model on a sample dataset and was pleased with the results of generating text. They then integrated weights from the original GPT-2 to

Testing Anthropic's Claude Haiku 4.5 on a WebSocket refactoring task revealed that while it produced the most code (13,666 tokens), it scored poorly in quality with a score of 74.4/100, ranking 7th out of 8 models tested. In contrast, Claude Sonnet 4.5 generated 8,425 tokens but achieved a higher score of 89.0/100. The results indicate that increasing code volume doesn't necessarily lead to better

The author revisits their 4 kilowatt solar fence installation to share insights on its design and construction. They highlight the challenges in sourcing materials for small solar setups, as manufacturers primarily cater to utility-scale needs. Using their experience with Ironridge roof mounting systems, they adapted it for vertical mounting, combining Ironridge components with common hardware store items. The project aimed to equalize the costs of mounting solar panels and the panels themselves, achieving nearly equal costs: $100 per panel and $110 per panel

The content discusses the challenges of managing outdated dependencies in software development, particularly focusing on the transition from the rest-client gem, which is no longer actively maintained, to a more current alternative like Faraday. The author highlights the assessment process for determining "abandonedness" based on factors like release frequency and community engagement on platforms like GitHub. While migrating from rest-client to Faraday, the author notes the absence of a direct replacement for a specific feature: the ability to use an indexing method (using
