The excerpt discusses the historical evolution of calculus from its informal roots to a more rigorous foundation. Initially, calculus, developed in the 17th century, relied on intuitive concepts. French mathematicians focused on applying calculus in physics, while German mathematicians, in the 19th century, critiqued and sought to refine it by finding counterexamples. The article highlights Karl Weierstrass, who, despite initial struggles and outside pressures, contributed to establishing a more stable mathematical framework for calculus. The

Traditional vector search methods typically use sentence embeddings, which can lose fine-grained token-level details. ColBERT addresses this limitation by utilizing token-level multi-vectors, maintaining more nuanced information and improving search accuracy through contextual late interaction at the token level. While this method requires more computational resources and storage, making it challenging for large datasets, a potential solution is to combine sentence-level vector search with token-level late interaction reranking for efficiency and quality. The multi-vector approach can also be applied beyond text retrieval

The challenge of practical code generation using AI, particularly through Large Language Models (LLMs), remains significant. While LLMs can generate clean code samples, they cannot reliably create intricate features for comprehensive codebases due to the complex context of real-world development that includes domain logic, legacy architectures, and specific business constraints. Although AI-driven products like Cursor, Bolt.new, and Vercel V0 have gained attention for their functionalities and funding, they struggle with the context issue, making them more suitable for

Bert Hubert discusses the challenges posed by email security scanners, particularly from Microsoft, which now execute JavaScript in email links and allow POST requests, creating potential security risks. This shift complicates single-use sign-on and email confirmation systems. Hubert reflects on changing cyber norms since his early internet days, noting how what was once considered secure has evolved. His recent experience while building a site for monitoring the Dutch parliament highlights the frustrations with these security changes, as users faced issues with password-less sign-on due to

The author intends to write a post about Pitchfork, discussing its origins, characteristics, and future. Before diving into that, they address common perceptions about Rails performance and its reliance on databases. While it is often said that database bottlenecks hinder Rails applications because they are typically I/O bound, the author clarifies that scaling Rails applications is primarily about expanding server capacity since Rails is stateless and can scale horizontally. However, relational databases pose more significant challenges for scaling. Although vertical scaling (upgrading

The new Opengrep repository is available for access. Recently, Semgrep changed its licensing model, which has sparked disappointment. Despite having always appreciated Semgrep's scanning capabilities and the work of its community advocates and researchers, the licensing change is viewed negatively as it may hinder competition in the market. The author believes that effective competition should come from providing better paid offerings rather than limiting access to open-source licenses. They express excitement for OpenGrep, an open-source alternative supported by multiple security vendors, and

On November 20, 2024, Shubham Shah and the author discovered a major security vulnerability in Subaru's STARLINK connected vehicle service, allowing unrestricted access to all vehicles and customer accounts in the U.S., Canada, and Japan. The vulnerability could have enabled an attacker to take control of a Subaru vehicle using only a victim's last name and ZIP code, email address, phone number, or license plate. The authors demonstrated they could take over a Subaru in about 10 seconds and retrieve

The author expresses enthusiasm for fully automated pipelines in design and manufacturing, particularly in the context of a recent speaker project. Previously constrained by the size limitations of their 3D printer, the author was inspired by a video of Richard from RMC 3D, who successfully created an arcade machine using several smaller printers by splitting the design into parts that were easy to assemble. This prompted the author to consider automating the segmentation process for their speaker design, focusing on panel-type structures. They plan to adapt

The author is seeking employment in audio, signal processing, and embedded systems. The post discusses audio processing using ffmpeg's libav* libraries, which are known for their complexity compared to the command-line API. It aims to clarify concepts related to media files, streams, packets, and codecs. Media files contain streams divided into packets, which may need decoding into raw PCM audio for processing. The author notes that while handling various audio formats can be cumbersome, converting them to a desired variant is possible.

The content discusses the difference between the game development industry and the tech industry in terms of project evaluation and funding strategies. Game developers create a "vertical slice," a polished, playable segment of the game that showcases its mechanics and aesthetics, which they present to publishers and investors as proof of their capability to deliver a high-quality finished product. In contrast, the tech industry often relies on a "minimum viable product" (MVP) approach, which focuses on producing the simplest version of a product that can be
