Ghostty Terminal Emulator Reaches 1.0: A Journey of Challenges and Triumphs

2024-12-28

Mitchell Hashimoto's journey to release Ghostty 1.0, his terminal emulator, spanned two years and overcame numerous challenges. Initially a personal project to explore Zig and graphics programming, Ghostty unexpectedly gained significant traction. To balance family life and development, Hashimoto employed a private beta, yielding invaluable community feedback but also resulting in frustration from those excluded. Ghostty 1.0 distinguishes itself with its unique tech stack (Zig core and platform-specific GUIs) and impressive performance. Future plans include open-sourcing the core library, libghostty, to further expand Ghostty's impact.

SBCL Compiler Optimization: Speeding Up Compilation of (lambda () nil)

SBCL Compiler Optimization: Speeding Up Compilation of (lambda () nil)

The SBCL compiler received a significant optimization that dramatically improves the compilation speed of empty functions like `(lambda () nil)`. Previously, compilation generated many redundant functions. This optimization identifies and handles these special cases, directly returning a predefined empty function, thus avoiding unnecessary computation and significantly increasing compilation speed. This improvement is especially effective when dealing with large amounts of code containing empty functions, reducing compilation time and boosting developer productivity.

Camembert Cheese May Improve Cognitive Decline

2024-12-27

Camembert Cheese May Improve Cognitive Decline

A new study has found that fatty acid amides present in Camembert cheese can improve cognitive decline in mice. Researchers used the object recognition test and found that orally administered Camembert cheese improved cognitive decline induced by a high-fat diet. Further investigation revealed that myristamide (MA), a fatty acid amide produced during Camembert cheese fermentation, improved cognitive decline, while its non-amidated counterpart, myristic acid, did not. This suggests that fatty acid amidation may be crucial for this physiological activity. Furthermore, MA increased the expression of brain-derived neurotrophic factor (BDNF) in the hippocampus.

Phugoid Oscillation: A Pilot's Nightmare

2024-12-27

A phugoid is an aircraft motion characterized by a repetitive cycle of climbing and descending, accompanied by changes in airspeed. Caused by variations in pitch and a nearly constant angle of attack, it can be triggered by factors like elevator input or control surface malfunctions. While sometimes a manageable nuisance, uncontrolled phugoids have been implicated in numerous aviation accidents, including the devastating Japan Airlines Flight 123 crash. Understanding phugoid dynamics is crucial for flight safety.

Pseudonymity in Academic Publishing: A Wikipedia Edit Sparks Debate

2024-12-27

A paper on editing mathematics on Wikipedia has sparked a debate about pseudonymity in academic publishing. One of the authors used the Wikipedia pseudonym "XOR'easter," but the American Mathematical Society (AMS) refused to publish the paper because they didn't know the author's real-world identity. This highlights the conflict between internet pseudonymity and traditional academic publishing, and the question of how readily academia accepts anonymous publications. The authors argue that Wikipedia's pseudonymity policy protects editors, and that academia needs to rethink the meaning of anonymous publication.

Hackers Face Lawsuit After Exposing Polish Train Manufacturer's Manipulation

The Chaos Computer Club (CCC) is raising funds for three hackers who revealed at the 37C3 conference how Polish rail vehicle manufacturer Newag manipulated its trains to be repairable only in its own workshops. Newag reacted with a 90s-style aggressive lawsuit, pursuing both criminal and civil charges. The legal costs have already reached €30,000. The CCC is calling for donations to cover legal and other expenses. The hackers' research did not involve any illegal replacement of train components. The CCC believes Newag's lawsuit aims to prevent future publications about these 'illegal instructions,' emphasizing that only the content teams decide who speaks at the congress.

Insights into the Structure of Neural Embeddings

This article explores the structure of embeddings (latent spaces) produced by deep neural networks. Several key hypotheses are summarized: the Manifold Hypothesis (high-dimensional data lies in a low-dimensional manifold); Hierarchical Organization (features organize hierarchically across layers); Linear Hypothesis (neural networks represent features as linear directions in their activation space); Superposition Hypothesis (neural nets represent more independent features than a layer has neurons); Universality Hypothesis (circuits reappear across different models for the same data); Adversarial Vulnerability (small input changes cause large embedding shifts); and Neural Collapse (after training, class features cluster tightly around their means). These hypotheses collectively illuminate the complexity and potential limitations of deep neural network embeddings.

This article delves into the discrepancy between Unix time (the number of seconds since January 1, 1970) and the actual time due to the Earth's slowing rotation and slight variations in its orbit. Leap seconds were introduced to address this, but their complexities lead to a plan to discontinue them by 2035. The author proposes a novel solution: periodically adjusting Earth's orbit to maintain synchronization between the solar year and the average Gregorian calendar year, thereby eliminating the need for leap seconds.
