The author discusses their experience working on character-property regular expressions for the Quamina programming language, focusing on utilizing the Unicode Character Database (UCD). They initially attempted to generate a large amount of code but abandoned that path due to the excessive size of 1.5 million lines. Instead, they are now using a more efficient approach to enable regex support in Quamina with a recent pull request. The author highlights the challenge of finding updated character properties, noting that Go's Unicode libraries lag behind the latest

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 journey with programming languages, noting that while C was the first language they learned thoroughly through "K&R," it has become less common in their work. Instead, they primarily use C# for modding a game and shell or Python for automation tasks. Despite this, they occasionally return to C or C++ for creating library bindings or addressing specific language gaps, appreciating C as a prototyping language. The author points out that C lacks standardization in coding style and practices, leading

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-

At least 21 people have died and many others have been injured in a train collision in southern Spain, marking the country's worst rail accident in over a decade. The incident occurred when a Madrid-bound train derailed, crossed into the opposite tracks, and collided with an oncoming train in Adamuz, near Córdoba. Approximately 400 passengers and staff were on board both trains, with at least 24 people reported as seriously injured, including four children. Spanish Transport Minister Óscar Puente called the

The author reflects on their experience browsing HackerNews, a platform they appreciate for its focus on technology and minimal political discussion. They enjoy seeing open-source projects shared, despite recognizing the fear and vulnerability associated with "shipping" such work. However, they noticed a thread where users questioned the validity of an open-source project, speculating that it might be AI-generated due to discrepancies in the commit timeline and coding style. The author believes it's important for developers to disclose any use of AI in their projects, especially

The content discusses the development of a pure C inference model for image generation called FLUX.2-klein-4B by Black Forest Labs. It highlights that the program can generate images from text prompts or other images and operates without external dependencies, apart from the C standard library, with optional MPS and BLAS acceleration. The project, initiated by Salvatore over a weekend, is notable for being an open-source effort where he did not write any code himself. Instead, he utilized Claude Code for

A$AP Rocky's recent music video for "Helicopter" features an innovative use of volumetric performance capture, creating dynamic visuals that evoke the energy of early MTV. The project, led by director Dan Strait and involving teams from Evercoast, Grin Machine (CG Supervisor Chris Rutledge), and WildCapture, aimed to push creative boundaries in post-production through this technology. Rather than using traditional filming techniques, the decision to implement volumetric capture was driven by a desire for radical flexibility in

The author reflects on neglecting their Photos library for nearly twenty years, during which they amassed a large number of photos, particularly of their child riding a camel in Morocco. They grapple with storage issues on their aging Intel MacBook, considering expensive upgrades but ultimately deciding to reduce their photo library size. Attempts to use existing photo management apps were unsuccessful—most only detected exact duplicates or lumped together images from the same time period, ignoring the subtleties of similar images. Frustrated, the author
