In 2025, Dr. Ing. h.c. F. Porsche AG sold 279,449 cars globally, a 10% decline from 310,718 in 2024. This reduction was expected and attributed to supply gaps for the 718 and Macan models, weaker demand in China, and a strategic focus on value-oriented supply management. Despite the dip in overall sales, Porsche highlighted successful product launches, such as the 911 Turbo S and the Cayenne Electric, indicating strong

Wilson Lin from Cursor has been experimenting with a large team of "autonomous" coding agents to see how effectively they can collaborate on a project. In their latest endeavor, they attempted to build a web browser from scratch using hundreds of concurrent coding agents who executed pre-defined tasks managed by planners and sub-planners. This approach was similar to that used by another system called Claude Code. In their experiment, the agents wrote over a million lines of code across 1,000 files over a week, generating

NanoLang is an experimental, minimal programming language designed for coding with large language models (LLMs). It features a clear, modern syntax aimed at enhancing both human readability and AI code generation, while also enforcing mandatory testing. The language transpiles to C for native performance and supports true self-hosting via a multi-stage bootstrap process. NanoLang is compatible with Windows 10/11 through the Windows Subsystem for Linux (WSL2) since its dependencies are Unix/POSIX libraries. Currently,

On January 19, 2026, the Space Weather Prediction Center reported that G4 levels of space weather were first achieved at 2:38 PM EST due to the arrival of a coronal mass ejection (CME). The passage of the CME is expected to continue into the evening, with the possibility of maintaining G4 levels. The information is provided by the National Oceanic and Atmospheric Administration's National Weather Service and National Centers for Environmental Prediction.

The author reflects on the changing nature of user-program relationships, noting a shift from user control to programs demanding user compliance, particularly regarding account creation. Older programs allowed users to dictate their needs, but newer applications, often called "apps," insist users create accounts, even when unnecessary. This trend leads to annoyance as users face constant security requests and updates, which often feel intrusive. The author cites examples of programs that successfully operate without requiring accounts or frequent updates, arguing that users do not always need or want

On January 8, 2026, a routine update to the DNS service 1.1.1.1 aimed at reducing memory usage inadvertently caused widespread DNS resolution failures due to a change in the order of records within DNS responses. While most software disregards the order of records, certain DNS implementations expect CNAME records to be positioned first. This misalignment led to failures in DNS queries. The change was initially introduced on December 2, 2025, released to testing on December

Burhan Khanzada, a software engineer with experience in Android and Flutter development, joined Slint in September as a Working Student. He is currently working on integrating the Servo browser engine into Slint applications to allow web content rendering. This transition from Flutter to Rust involved learning about Rust's ownership model and low-level graphics programming techniques. The need to render web content in modern applications, such as for OAuth flows or documentation, led to this integration, which bridges two rendering systems while ensuring cross-platform compatibility

In this article, Oskar Dudycz discusses an edge case encountered in the context of Event-Driven Architecture when rebuilding inline projections from PostgreSQL stored events. The previous design involved using a hybrid locking strategy to ensure that only one rebuild operation occurs at a time. However, a potential flaw was identified where the rebuild process could mistakenly declare success even though an important event is still pending in an uncommitted transaction. This can lead to situations where the projection is marked as active despite missing the newly appended

The content discusses a probability problem involving a ladybug that moves randomly between the numbers on a clock, starting at 12. Each time she lands on a number, it is colored red, and the goal is to determine the probability that the last number she visits is 6. Initially, it seemed that the distance from 12 to 6 would influence its probability, but simulations showed that the likelihood of any number being the last colored is roughly equal, converging to approximately 9.09%

WebAssembly (Wasm) has evolved from enhancing browser performance to becoming a leading technology in backend environments, functioning as a lightweight alternative to Docker containers for tasks like serverless functions and AI processing. Its main advantage lies in its sandboxed environment, designed to be "safe by design" through strict controls and isolation from the host system. However, as backend complexity increases, vulnerabilities such as "Linear Memory" issues and JIT-compiler bugs are emerging, enabling malicious modules to circumvent this safety and potentially

In a recent blog post, David Heinemeier Hansson, creator of Ruby on Rails, shares his perspective on the current capabilities of AI in programming. He contrasts the Silicon Valley narrative that AI can replace junior programmers with his own observations, noting that AI is not as effective as many junior developers at coding. Hansson describes AI tools as akin to a "flickering" light bulb, sometimes providing valuable insights but often failing to deliver consistent quality. He emphasizes that while AI-generated code may work

Arrays in PostgreSQL can be easily initialized by declaring a column as integer[] and inserting values, but they come with complexities beyond basic usage. They involve their own memory management and indexing, which can create issues in production environments. The article emphasizes that arrays should not be confused with JSONB arrays, as using arrays is akin to document storage, prioritizing data locality over normalization, similar to NoSQL databases. When embedding data, such as tag IDs in an array, it simplifies data retrieval but compromises relational

In a previous post about Peter Naur’s idea of "Programming as Theory Building," it was argued that a program consists of the shared mental model of its creators rather than just its source code. When those developers leave or lack comprehension, the underlying theory fades, leaving behind an incomprehensible codebase. The author reflects on a deeper issue: it's not just that individual developers are losing their theoretical skills, but that the institutions facilitating theory-building—like teams, companies, and the software development profession—

The author reflects on their initial reaction to the Haskell documentation describing arrays as functions defined over contiguous integer subsets. Initially amused by the formalism, they now appreciate this description as capturing the essence of arrays, emphasizing that it has remained memorable over the years. This leads to a discussion on the allure of unifying arrays and functions in programming languages for simplification purposes. However, the author notes that while such a correspondence exists, it doesn't mean practical implementations, like those in Haskell or the research language

Rijnard van Tonder discusses the complexities of building agents in the tech ecosystem, which often involves navigating numerous tools and concepts. He proposes a simplified approach where the agent operates with a single powerful tool: the ability to execute code. Instead of using traditional command line tools like `bash`, `ls`, or `grep`, the agent only executes code, reshaping the interaction from questioning which tools will be used to focusing on the code generated and executed by the agent. This method emphasizes a Code-
