Indie Dev Uses C for a 2025 Commercial Game: A Postmortem

2025-01-20

Cowleyfornia Studios released their train management game, *Iron Roads*, in 2025, surprisingly written in pure C (C99) instead of C++. The choice stemmed from a desire for portability, simplicity, and most importantly, code clarity to manage memory allocation and performance. Prototypes in Haskell, Go, and Rust were explored, but ultimately C (approx. 40,000 lines of code) and Lua (approx. 8,000 lines for higher-level logic) were chosen. The developer found C's fast compilation and ease of optimization beneficial to the workflow, but admitted to challenges with serialization and boilerplate. While happy with the outcome, they are unlikely to repeat the process, leaning towards modern, higher-level languages that compile to C, like Nim, for future projects.

Earthquake Early Warning: The Speed-Accuracy Tradeoff in Magnitude Estimation

2025-07-23
Earthquake Early Warning: The Speed-Accuracy Tradeoff in Magnitude Estimation

A major challenge in Earthquake Early Warning (EEW) systems is real-time estimation of earthquake magnitude. Magnitude determines the extent of shaking and who needs warning. Underestimation risks missed warnings, while overestimation leads to false alarms and erosion of public trust. The key challenge lies in balancing speed and accuracy; initial data is limited, but delaying alerts reduces warning time. Over the past three years, we've significantly improved magnitude estimation, reducing the median absolute error from 0.50 to 0.25. Our accuracy now rivals, and in some cases surpasses, established seismic networks.

The Evolution of PuTTY's Icons: From Hand-Drawn to SVG

2025-03-12

This article chronicles the evolution of PuTTY's icons from hand-drawn images in the 1990s to today's scalable SVG vectors. The author initially created 32x32 pixel icons using the MSVC icon editor, constrained by the 16-color palette and display technology of the time. Over time, to accommodate higher resolutions and the needs of various tools, the author refined the process, eventually developing a script that auto-generates icons in multiple sizes and formats. This culminated in SVG versions, achieving true scalability. The design philosophy remains simple and clear, reflecting PuTTY's 'reassuringly old-fashioned' style, and continues to be used to this day.

Dune vs. Lawrence of Arabia: A Comparative Analysis

This article explores the similarities and differences between Frank Herbert's *Dune* and T.E. Lawrence's *Seven Pillars of Wisdom*. Both Paul Atreides and Lawrence function as outsiders who immerse themselves in desert cultures to lead indigenous populations against their oppressors. However, significant contrasts emerge in their portrayals of the Arabs and Fremen, their treatment of women and religion, and their emotional responses. Lawrence reveals profound self-doubt and guilt over his actions, while Paul displays excessive confidence and a ruthless pursuit of power. Furthermore, *Dune* features prominent female characters and a rich tapestry of religious themes, absent in Lawrence's largely male-centric and religiously understated narrative. While *Dune* draws inspiration from *Seven Pillars*, it ultimately forges a unique and compelling world of its own.

Bangkok Basin's Long-Period Ground Motion: A Love Wave Story

This study analyzes horizontal elastic response spectra of earthquake ground motion in the Bangkok basin. It finds significant amplification of spectral energy at long periods (0.5-2s) within the basin, linked to surface wave arrivals. Analysis of different parts of accelerograms confirms that long-period energy is associated with surface wave propagation, not source effects. HVSR analysis reveals predominant frequencies between 5.1-5.5s for basin stations, consistent with elastic spectra. Analysis of the 2008 Mw 7.9 event shows that low-frequency ground motion (0.1-0.3Hz) in the basin is influenced by locally generated surface waves, particularly Love waves. Further research is recommended, including large-array observations with reliable low-frequency seismometers and 2D/3D basin-structure ground motion modeling.
