Generating crossword puzzles is an NP-Complete problem due to the constraints that intersecting words create across the grid. As a result, there is no efficient algorithm that guarantees a solution, but effective heuristics can produce satisfactory outcomes. In late 2021, the author, inspired by a passion for the New York Times Crossword during lockdown, embarked on a project to create a crossword app. This led to the development of "Crosswarped," an iOS and Android game utilizing an algorithm for generating cross

The essay "When 2 + 2 Does Not Equal 4.0" explores the concept of equality in programming languages, highlighting the distinction between functional equality and semantic equality. It begins by discussing how incorrect assumptions about equality can lead to unexpected behaviors, as illustrated by JavaScript's treatment of different values like "" and [0], which are equal to 0 but not to each other. The essay references Leibniz’s Law, which posits that two things are identical if they share

A couple of months ago, the author received a request to add CSRF protection to their web framework, Microdot. Initially, they planned to incorporate traditional methods like anti-CSRF tokens and double-submit cookies. However, they discovered a simpler approach to mitigate CSRF attacks. Despite the common advice against implementing security features independently—favoring established solutions—the author, as the sole maintainer of Microdot, felt compelled to create a CSRF protection mechanism themselves due to the lack of existing options. They

The content emphasizes the importance of user feedback and acknowledges its receipt. It directs users to the documentation for available qualifiers and provides an example of building the "iced" GUI framework for Android. It mentions that users can run examples from iced, excluding certain rendering parts, and outlines some functionality issues with text input, such as copy/paste and keyboard visibility, which require Java calls. The document references the "android-activity" crate for detailed guidance and explains that although iced does not natively support Android,

Yusuf Mohammad discusses the implications of running an ONNX model with ONNX Runtime (ORT) using the CoreMLExecutionProvider, which can affect model predictions due to default behavior that casts models to FP16. To ensure the model remains in FP32 on a Mac GPU, a specific setup for the InferenceSession is recommended. After training the EyesOff model, evaluations showed discrepancies in outputs when comparing model performance between ONNX on MPS, ONNX on CPU, and PyTorch on both platforms

The article initially discussed the viability of local coding models, suggesting they could potentially replace higher-cost coding subscription services. However, after community feedback, the author acknowledged a mistake in their hypothesis, correcting it from a tentative endorsement to a clear recommendation against dropping existing coding subscriptions for local models. The author emphasizes that while local models can perform approximately 90% of software development tasks, the final 10%—crucial for professional environments—is where these models fall short. They clarify that their perspective was

Crunch is a C++ message definition and serialization framework designed for mission-critical and resource-constrained systems. It emphasizes the importance of message semantics alongside structure and includes features such as built-in field and message validation. Crunch is header-only, requires C++23, and does not use STL libraries for dynamic memory allocation. Users can integrate it by copying the include directory into their project and configuring their build system accordingly. Validation occurs during the serialization and deserialization processes, but it can be bypassed if needed.

The author invites technically inclined readers to attempt building a semaphore from scratch in their preferred programming language, sharing their own challenging experience with Go, which was more difficult than expected due to concurrency and locking bugs. Semaphores are used in programming to manage access to shared resources and limit concurrent task execution. The author illustrates a problem that can arise from not using semaphores when exceeding file descriptor limits in an operating system. In Go, channels facilitate communication between goroutines but lack a first-in-first-out (
