Ubuntu 25.10 Drops Xorg Support for GNOME, Embraces Wayland Exclusively

Ubuntu 25.10, codenamed "Questing Quokka," is making a significant change: the default GNOME desktop will exclusively use Wayland, dropping support for Xorg. This isn't a sudden decision; GNOME is phasing out Xorg support, and Canonical is proactively adapting. This allows users and developers a full release cycle to adjust before the next LTS, Ubuntu 26.04, arrives next year. The move is driven by Wayland's maturity, improved Nvidia driver support, better touchscreen and high-DPI display handling, and a simplification of development by avoiding maintaining two display servers. While some users rely on Xorg, it won't disappear entirely; it can still be installed and used with other desktop environments. Most X11 applications will continue to function via XWayland.

The Rise and Fall (and Rise?) of Book Blurbs

This article delves into the controversial world of book blurbs—those quotes of praise adorning book covers. While acknowledging the time-consuming and often hyperbolic nature of blurbs, the author argues that they remain a crucial element in a crowded publishing landscape. Blurbs help readers filter through the massive number of books published, assist book reviewers and sellers in their choices, and ultimately contribute to a book's success, especially for lesser-known authors. The author suggests reforms to improve the blurb system, including limiting their number, avoiding blurbs for unsold manuscripts, and encouraging established authors to prioritize giving opportunities to newer voices.

Hegel 2.0: The Unrealized Revolution of Ternary Computing

This article explores the Cold War clash between the US and Soviet Union in computer science and philosophy. Warren McCulloch's refusal of a Soviet invitation sets the stage for a narrative about the ternary computer SETUN and its connection to McCulloch's neural network theory and Gotthard Günther's 'transclassical logic'. Günther sought to synthesize Hegel's dialectic with cybernetics, arguing that ternary logic could solve contradictions inherent in binary logic and provide a foundation for a digital metaphysics. Though SETUN ultimately failed, it spurred exploration of non-binary computing and prompted reconsideration of binary oppositions in digital culture.

Harvard Grad, LSD Kingpin: The Collision of Sixties Idealism and Nineties Materialism

William Leonard Pickard, a Harvard graduate, was arrested for allegedly being one of the world's largest LSD manufacturers. This article chronicles his legendary and complex life: from a privileged childhood in Atlanta to the heart of the 1960s counterculture and social drug research at prestigious universities in the 1990s. He associated with rock star Sting, befriended members of the British House of Lords and US officials, and earned a master's degree from Harvard's Kennedy School of Government. However, he served multiple prison sentences for drug manufacturing and, while attempting to lead a legitimate life, was again caught up in the drug trade through his collaboration with Gordon Todd Skinner, a drug dealer. Pickard's story is a microcosm of the clash between 1960s idealism and 1990s materialism, a cautionary tale about the conflict between the dreams of the counterculture and the harsh realities of life.

LLVM-MCA Performance Analysis: Pitfalls of Vectorization Optimization

LLVM-MCA Performance Analysis: Pitfalls of Vectorization Optimization

The author encountered a performance degradation issue when vectorizing code using ARM NEON. The initial code used five load instructions (5L), while the optimized version used two loads and three extensions (2L3E) to reduce memory accesses. Surprisingly, the 2L3E version was slower. Using LLVM-MCA for performance analysis revealed that 2L3E caused bottlenecks in CPU execution units, unbalanced resource utilization, and stronger instruction dependencies, leading to performance regression. The 5L version performed better due to its more balanced resource usage and independent load instructions. This case study highlights how seemingly sound optimizations can result in performance degradation if CPU resource contention and instruction dependencies aren't considered; LLVM-MCA proves a valuable tool for analyzing such issues.
