In September 2023, KrebsOnSecurity reported that a series of cyber heists, resulting in six-figure losses for multiple victims, were traced back to master passwords stolen from LastPass in 2022. Federal agents investigating a $150 million cryptocurrency theft in January 2024 came to a similar conclusion. They seized about $24 million in cryptocurrencies linked to the heist, which affected Chris Larsen, co-founder of Ripple. The seizure confirms insights from the earlier report about ongoing heists where

In February 2025, the discussion focused on the development of Polars, a DataFrame library that aims to address the shortcomings of existing data manipulation libraries like pandas and PySpark. The author noted that while SQL has been versatile and optimized for various environments (embedded, client-server, OLAP warehouses), DataFrame implementations differ significantly based on use cases, leading to performance issues. Pandas is user-friendly but lacks several optimizations known from decades of database advancements, resulting in poor scalability. On the

This post discusses how Rails processes incoming HTTP requests and how to access the request object within a controller. HTTP operates as a request-response protocol, where the browser (client) sends a request to the server (Rails application), which processes it and returns a response. The request contains valuable information that the application uses to handle it appropriately. Rails provides an easy interface for accessing the current HTTP request through the `request` method, available in controller classes, which returns an instance of the ActionDispatch::Request

The paper "From Game of Life to Pattern Generation with Learned Recurrent Circuits" by Pietro Miotti and colleagues from Google explores the potential of using a fully differentiable approach to develop cellular automata that can learn local rules for generating complex patterns from simple specifications. Traditionally, cellular automata involve a bottom-up approach where local rules are predefined and emergent behaviors are studied. The authors propose combining Neural Cellular Automata (NCA), capable of learning patterns but lacking within a discrete state framework, with

Michael Lynch discusses the importance of effective commit messages in software development, illustrating their role in simplifying code reviews and aiding long-term maintenance. He notes that many commit messages are vague or unhelpful, such as "Fix bug" or "Update UI." Through his 20 years of experience, he emphasizes that a good commit message should clearly describe the change and its impact. For example, he provides the message: "Delete comments for a post when the user deletes the post," which gives context about a

The content discusses the tail latency problem in distributed systems, where a small percentage of requests experience significantly longer response times, negatively impacting user experience. This issue can disrupt service-level agreements (SLAs) despite the majority of requests being processed quickly. The solution presented is "hedging," a technique employed by major companies like Google and Grafana to mitigate latency spikes. Hedging involves sending multiple requests for the same operation and using the fastest response, akin to a user trying to secure a concert ticket
