The content emphasizes the importance of user feedback and provides a brief overview of a project involving running Linux within Excel. The project utilizes a mini-rv32ima emulator, which is built as a separate DLL and accessed through a VBA macro that inputs the emulator's output into Excel cells. Although the project is functional, it is described as "buggy" and was primarily conducted for fun, without rewriting the emulator in VBA or Excel formulas. Additionally, it mentions using MSVC to build the DLL and provides

The author discusses their experience building an HN (Hacker News) API client as part of the project hn.unlurker.com, focusing on utilizing the latest features in Go. The client enables the retrieval of active items (comments and stories) and includes a feature to download all items as a comprehensive JSON file. After successfully downloading a 20 GiB file containing all Hacker News data, the author initially used grep to analyze the content but then opted to use DuckDB, a fast and embedd

The author has developed a Ruby tracing profiler that tracks four types of events—Ruby function calls, system calls, thread-state changes, and garbage collection—while maintaining low overhead (under 30 nanoseconds per function call), making it suitable for production environments. The profiler reportedly provides a unique combination of signals compared to existing tools, such as ruby-prof, which has significantly higher overhead (538 ns). Although the profiler is currently in a proof-of-concept stage and not yet open-sourced, interest from

IBM Research, in collaboration with CMU, Princeton, and the University of Illinois, has developed an open-source large language model (LLM) called Bamba. This model uniquely combines the capabilities of transformer architectures with the speed of state-space models, addressing issues related to the quadratic memory and processing costs associated with longer conversations in traditional transformers. Bamba is expected to feature prominently in IBM's upcoming Granite 4.0 models. An event discussing the optimization of LLM inference performance will be held on

The content discusses the implementation of a technique called CoRT, which enhances AI models by encouraging them to recursively evaluate their responses, generate alternatives, and select the best option. This method allows AI to "doubt" itself and improve its outputs through repeated iterations. The author tested this with the Mistral 3.1 24B model, noting a significant improvement in performance, particularly in programming tasks. The author invites contributions to further enhance this technique and mentions that the project is open-source under

The author is developing a programming language and acknowledges the difficulty involved in language design, particularly in parsing. They propose a simplified approach by minimizing the number of syntax elements to just five, which would ease parsing challenges, especially for C-family languages. Instead of traditional constructs like switch/case statements and loops, the author suggests using simpler alternatives such as if statements and named recursion. They argue that many features common in programming languages, like pattern matching and parametric polymorphism, are unnecessary. The design leans

The content discusses the concept of Zero Trust Architecture (ZTA), which aims to address vulnerabilities in complex systems, as illustrated by the Swiss Cheese model. Catastrophic failures often result from multiple smaller failures rather than a single disaster. ZTA emphasizes the importance of eliminating implicit trust within networked systems, especially given the rise of non-human identities and distributed cloud systems. It advocates for strong identity verification and continuous auditing of all users and devices. The principles of ZTA, first established by NIST in

Amazon RDS for PostgreSQL is an AWS service that offers managed instances of the PostgreSQL database. A recent study by Jepsen revealed that multi-AZ clusters of Amazon RDS for PostgreSQL can violate Snapshot Isolation, the strongest consistency model available. This issue, including instances of Long Fork and G-nonadjacent cycles, was observed across all tested versions (13.15 to 17.4). As a result, Amazon RDS might only provide Parallel Snapshot Isolation instead. Post

The author expresses frustration with the complexities of code performance optimization, emphasizing that it is a brute-force task that requires careful consideration of various approaches. While discussing the nuances of optimization, the author notes that some techniques can work well in isolation but may lead to worse performance when combined, highlighting the need for deep expertise in selecting the right strategies. The author also shares personal challenges in exploring optimization options, particularly in algorithm design, due to the myriad of choices and their interdependencies. Furthermore, they critique the idea

The text discusses the differences between Ancient Greek orthography and modern English orthography, emphasizing that Ancient Greek more closely represented spoken language. It highlights the presence of hesitations and meaningless expletives in speech that are not captured in writing. The author provides examples of these expletives in English speech, drawing from a collection of 327 spoken texts of varying lengths. Observations indicate that these expletives typically occur before or immediately after major syntactic constituents. Examples illustrate their placement in various contexts within
