Video games are art, but a strange art: their essence is transformation of the player, not description to the player. This makes meaningful criticism nearly impossible—you can point at the moon, but it’s not the moon, and once someone sees it, they no longer need the pointing. | |

| 144. | Memory layout in Zig with formulas | (raymondtana.github.io) |
|
|
I was recently encouraged to watch A Practical Guide to Applying Data Oriented Design (DoD) by Andrew Kelley, the creator of Zig1. Just 10 minutes into the talk, I was confronted with a skill I had never formally learned… the arithmetic behind memory layout of types. Zig is a modern, C-like programming language which offers a safer, more memory-explicit experience for systems programming, without sacrificing low-level control or C interoperability. Notably, Zig makes it straightforward to manage memory allocation by treating allocators as first-class values rather than hidden globals. Instead of relying on an implicit runtime or a process-wide allocator, you pass explicit allocator objects into the code that needs them. This makes ownership and lifetimes much clearer, encourages you to design APIs around who is responsible for allocating and freeing memory, and makes it easy to swap in custom allocation strategies (e.g., arenas, scratch, tracking, etc.). ↩ | |

| 148. | An ultra-high-resolution map of (dark) matter | (nature.com) |
|
Ordinary matter—including particles such as protons and neutrons—accounts for only about one-sixth of all matter in the Universe. The rest is dark matter, which does not emit or absorb light but plays a fundamental role in galaxy and structure evolution. Because it interacts only through gravity, one of the most direct probes is weak gravitational lensing: the deflection of light from distant galaxies by intervening mass. Here we present an extremely detailed, wide-area weak-lensing mass map covering 0.77° × 0.70°, using high-resolution imaging from the James Webb Space Telescope as part of the COSMOS-Web survey. By measuring the shapes of 129 galaxies per square arcminute—many independently in the F115W and F150W bands—we achieve an angular resolution of $$1.00\pm 0.0{1}^{{\prime} }$$ . Our map has more than twice the resolution of earlier Hubble Space Telescope maps, revealing how dark and luminous matter co-evolve across filaments, clusters and underdensities. It traces mass features out to z ≈ 2, including the most distant structure at z ≈ 1.1. The sensitivity to high-redshift lensing constrains galaxy environments at the peak of cosmic star formation and sets a high-resolution benchmark for testing theories about the nature of dark matter and the formation of large-scale cosmic structure. JWST’s COSMOS-Web survey is used to create an ultra-high-detail dark matter map, revealing hidden filaments, clusters and distant structures. By tracing features out to z = 2, this map shows how dark and luminous matter build the cosmic web across cosmic time. | |
