The developer has received positive feedback about the name "Script" and plans to keep it until mid-February while considering alternatives. They have created a project called Script, which compiles JavaScript and TypeScript into native machine code without garbage collection. This enables high performance comparable to Rust, with features like SSA-based intermediate representation and self-contained executables. The developer's journey included attempts to build a hybrid framework and optimize performance benchmarks, ultimately realizing that a new language combining Rust and JavaScript/TypeScript

The author describes their experience of designing robot parts using traditional CAD software and the drawbacks of that approach, such as manual adjustments and repeated workflows. To improve the process, they developed a tool called "vcad," which allows users to design parts in a coding-like environment using Rust. In vCAD, parts are defined by geometry with straightforward operations: creating primitives, combining them using boolean operations, and exporting designs. The syntax is simple and operates similarly to arithmetic, making the process of creating complex shapes efficient

The content outlines the functionality and usage of the Time Station Emulator, which allows phones and tablets to act as low-frequency radio transmitters to synchronize radio-controlled ("atomic") clocks and watches. The emulator is designed to help clocks that may not receive adequate real-time signals due to geographic limitations or urban interference. To use the Time Station Emulator, devices must support WebAssembly and have a Digital-to-Analog Converter (DAC) capable of ≥44.1 KHz PCM. While most modern devices should work

A customer shared their debugging process involving Honeybadger and GitHub Copilot, questioning whether Copilot could directly access Honeybadger to streamline their workflow. Indeed, it can, thanks to GitHub Copilot's custom agents that support Model Context Protocol (MCP) servers. The honeybadger-mcp-server, released in 2025, enables integration with various tools, including Copilot. This article outlines how to build a custom Copilot agent that automates debugging and fixing errors. Custom

The content discusses the concept of "narrowing" types in Python, which is essential for type checkers like Pyrefly. Narrowing involves applying constraints to the potential values of variables or expressions, allowing for more accurate type inference. For example, using `isinstance(x, int)` narrows the type of `x` to `int` within the corresponding block. Since Python utilizes duck typing, type checks often focus on structural properties instead of class names. The blog post outlines various narrowing

The software industry operates under a "polite fiction" that estimating the duration of projects is feasible, though most engineers recognize this is false. Accurate estimations are notoriously difficult, leading to unconventional practices such as using t-shirt sizes instead of timeframes for estimates, which are then converted into time by management. Some engineers resort to unreliable heuristics like increasing initial estimates by a fixed percentage. The article suggests that while estimating can be tricky, it serves a purpose within organizations, and acknowledges that accurate estimations

In a recent episode of Radio24 titled "La scomunica digitale," the host discussed the case of Nicolas Guillou, a French ICC judge sanctioned by the Trump administration, which resulted in his ban from US territory and prohibited American entities from providing services to him. This situation was compared to the historical excommunication of philosopher Baruch Spinoza in 1656 for heretical views on God and the universe. Spinoza's excommunication, known as a herem, led to

The author expresses frustration over recurring issues with spin-locks encountered in multiple projects within a year. They have experience with both implementing and being affected by spin-locks and are motivated to write a blog post to prevent others from making the same mistakes. Although many others have addressed issues related to spin-locks—such as performance, fairness, priority inversion, and broken code—the author feels there is always more to discuss. They strongly advise against using spin-locks unless one is very knowledgeable about them, highlighting

The content highlights the security vulnerabilities of two tools, Clawdbot and Plinq, both of which have gained significant popularity and attention in their respective communities. Clawdbot, an autonomous agent with extensive access and control over a computer, poses a significant risk as it can execute commands based on messages it receives, undermining the traditional trust boundary of access. This vulnerability is exacerbated by the potential for prompt injection attacks, where malicious messages could lead to harmful actions executed by the agent. Pl

The content emphasizes that many activities related to planning or discussing a goal (referred to as "the thing") do not equate to actually taking action. It lists various forms of preparation, contemplation, and communication that, while potentially valuable, do not fulfill the act of doing. The key message is that true progress comes from taking action—no matter how imperfect or small it may be—rather than merely thinking about or preparing to do something. The author concludes by recognizing the need to focus on actual

Building multiplayer games, particularly in real-time collaboration, presents significant challenges, notably in developing a suitable data model and conflict resolution strategy. While understanding resources like Figma's multiplayer blog can provide initial insights, the complexity of managing infrastructure and costs remains. Collaboration engine products, which simplify this process, can be expensive and unnecessary for low-throughput scenarios with few users. The author shares their experience of creating a multiplayer sword fighting game without a sync server by utilizing a peer-to-peer (P2P) architecture
