Fundamental Problems of Lisp, the Cons Cell (2024)

Fundamental Problems of LISP, the Cons Cell (this essay is originally written around 2008) The Cons Business The other fundamental problem in the language is its cons cells as its list construction primitive. Lisp at core is based on functional programing on lists. This is a powerful paradigm. However, for historical reasons, lisp's list is based on the hardware concept of “cons” cell. From a mathematical, functional, API point of view, what this means is that lisp's “list” is limited to a max

Methane Pollution Has Cheap, Effective Solutions That Aren’t Being Used

wired.com Umair Irfan 2026-03-07 05:00:00

This story originally appeared on Vox and is part of the Climate Desk collaboration. Odorless and colorless, methane is a gas that is easy to miss—but it’s one of the most important contributors to global warming. It can trap up to 84 times as much heat as carbon dioxide in the atmosphere, though it breaks down much faster. Measured over 100 years, its warming effect is about 30 times that of an equivalent amount of carbon dioxide. That means that over the course of decades, it takes smaller a

The music industry is building the tech to hunt down AI songs

theverge.com Jack Buehrer 2026-03-07 06:00:00

The music industry’s nightmare came true in 2023, and it sounded a lot like Drake. “Heart on My Sleeve,” a convincingly fake duet between Drake and The Weeknd, racked up millions of streams before anyone could explain who made it or where it came from. The track didn’t just go viral — it broke the illusion that anyone was in control. In the scramble to respond, a new category of infrastructure is quietly taking shape that’s built not to stop generative music outright, but to make it traceable.

Augmented Vertex Block Descent (AVBD)

news.ycombinator.com Unknown 2026-03-07 03:04:56

Augmented Vertex Block Descent (AVBD) Vertex Block Descent is a fast physics-based simulation method that is unconditionally stable, highly parallelizable, and capable of converging to the implicit Euler solution. We extend it using an augmented Lagrangian formulation to address some of its fundamental limitations. First, we introduce a mechanism to handle hard constraints with infinite stiffness without introducing numerical instabilities. Second, we substantially improve the convergence in th

Cracovians: The Twisted Twins of Matrices

Linear algebra is typically explained using matrices. But matrix theory is just one possible perspective. Below, I describe an alternative approach to linear algebra. Tadeusz Banachiewicz (1882–1954), a Polish astronomer living in Krakow, was passionate about calculating machines. From the 1920s, Banachiewicz developed a method for computations on tables of numbers, which was particularly easy to perform with arithmometers. In honor of Krakow, Banachiewicz named these computational objects crac
