In July 2013, Y Combinator's advice emphasized the importance of doing things that don't scale for startup founders. Many aspiring entrepreneurs mistakenly believe that startups grow organically once a product is launched. However, success often requires active efforts from founders to drive growth. A key example is Stripe, which is known for its aggressive user acquisition tactics. Instead of passively waiting for users to adopt their service, the Collision brothers would personally engage potential users by setting them up on the spot. This process reflects

NASA astronaut Nichole Ayers captured a rare phenomenon known as a gigantic jet on July 3, 2025, while aboard the International Space Station. This event is a type of Transient Luminous Event (TLE), specifically a powerful electrical discharge that extends from thunderstorm tops into the upper atmosphere. Gigantic jets typically form during turbulent conditions in thunderstorms and create an electrical bridge between the clouds (about 20 km up) and the atmosphere (around 100 km). Unlike sprites, which

The author has reported an ongoing issue with game rendering on MacBook displays (FB13375033), which has been open since September 2023. When games are developed using AppKit or Catalyst for full screen on MacBooks, they may render incorrectly due to the presence of a notch at the top of the display. Normally, games use the CGDisplayCopyAllDisplayModes function to select the best resolution for the display, but this function does not properly account for the non-standard full screen area caused

The Ghostty team has successfully rewritten the GTK application, utilizing the GObject type system from Zig and employing Valgrind for memory verification throughout the process. This has led to a more stable, feature-rich, and maintainable version of Ghostty on Linux and BSD. Ghostty is a cross-platform terminal emulator that employs native GUI frameworks for macOS (using Swift and Xcode) and GTK for Linux/BSD, with a shared core written in Zig that exports a C ABI compatible API.

The author shares their experience with feeling imposter syndrome as a software engineer in the face of claims surrounding "10x engineers" who leverage advanced AI technologies to significantly boost productivity. Initially confident in their skills, the author began to doubt their capabilities after seeing others seemingly excel with AI tools, leading to anxiety about being left behind in their career. They were particularly overwhelmed by the advanced uses of AI that went beyond basic coding assistance, making them feel disconnected from the evolving landscape of engineering. Eventually, they resolved

The post, part of a series on connection management challenges, focuses on the critical role of reverse proxies in load balancing requests among upstream servers. While round-robin load balancing works at a small scale, it becomes complex in larger systems due to varying request types, leading to potential server overloads and underutilization. For instance, different requests like image uploads versus profile lookups demand different resource allocations. The text also discusses the need for request stickiness to specific hosts, which round-robin cannot address

The post discusses the concept of placing functions in Rust, which allow for returning values without copying, offering improved efficiency and stable addresses crucial for self-referential types. The author highlights the potential for adding #[placing] notation to the standard library progressively, ensuring backward compatibility with existing traits and functions. The need to avoid creating additional incompatibilities, similar to issues caused by the introduction of Pin, is emphasized. The author also notes the challenges associated with placing arguments, underlining that invoking functions with these arguments

Variance in the context of generics helps us understand how behaviors of generic types relate to subtyping. Generics are types that include placeholders, known as type parameters, which allow for code reuse with various data types. Examples include `list[T]` in Python, `std::vector<T>` in C++, and `List<T>` in Java. The main advantage of generics is enabling code compatibility across different types while often improving runtime performance through a process called monomorphization in compiled languages.

The author discusses their experience implementing liveness analysis using Datalog after a conversation with Waleed Khan. They begin by referencing a Control Flow Graph (CFG) example (Wimmer2010) and manually identifying which variables are live out of different blocks. The author notes a shift in approach using block arguments instead of phi functions, leading to the formulation of liveness in terms of two relations: live-in and live-out. While they had computed live-in sets previously, the goal is now to compute

The content discusses the growing integration of large language models (LLMs) like ChatGPT and Claude into software development, highlighting a trend towards "vibe coding." However, it raises concerns about biases in these AI tools, specifically a study from King’s College London that found LLMs predominantly use Python (90-97% of the time) for programming tasks, even when other languages would be more suitable. Rust was notably never used in the benchmark tasks. The author, a Python developer, expresses
