The Unix Trinity: dmr, kt, and bwk

2025-02-12

In Unix history, the initials dmr, kt, and bwk represent legendary figures: Dennis M. Ritchie (dmr), co-creator of Unix and the C programming language; Ken Thompson (kt), co-creator of Unix alongside Ritchie; and Brian W. Kernighan (bwk), co-author of influential Unix programs and books like "The C Programming Language" and "The UNIX Programming Environment". These three giants shaped the foundations of Unix and profoundly impacted modern computer science.

Nonlinear Optics Sandbox: AI-Powered Control of Complex Optical Systems

WestonCB's Nonlinear Optics Sandbox is an interactive platform for studying controlled nonlinear dynamics through the simulation of coupled optical fields. The project uses a specific optical configuration—coupled fundamental/harmonic fields interacting with an adaptive medium—as an idealized model to explore how optimization processes can guide complex nonlinear systems towards desired states. It combines real-time visualization, GPU-accelerated physics simulation, and gradient-based optimization, offering a novel tool for researching nonlinear dynamics and the control of complex systems.

Chrome Incognito Gets IP Protection: A Two-Hop Proxy for Enhanced Privacy

Chrome is introducing IP Protection for Incognito mode, enhancing privacy against cross-site tracking. Using a two-hop proxy system, users' original IP addresses are masked, protecting them from third-party tracking. Only domains on a Masked Domain List (MDL) are affected, and essential web functionality remains intact. Google and external CDNs operate separate proxies, preventing either from accessing complete user information. Launching after May 2025, users can disable the feature.

From Comfort Zone to Hyper-Growth: How to Gain 5 Years of Experience in 1-2

This article explores the variability in learning speed during career progression. The author argues that certain periods yield exceptionally high learning efficiency, akin to compressing years of experience into mere months. Using the acquisition of Drivy by Getaround as an example, the author recounts a high-pressure experience involving complex tasks and rapid personal growth. Four zones are introduced: Comfort, Learning, Fast Growth, and Burnout. The author suggests navigating flexibly between these zones, maintaining continuous learning, and avoiding stagnation in either comfort or prolonged hyper-growth.

CA AG Sues OMB to Block $3 Trillion Federal Funding Freeze

California Attorney General Rob Bonta, along with 22 other state attorneys general, filed a lawsuit against the Office of Management and Budget (OMB) to block a directive that would freeze up to $3 trillion in federal funding. The directive threatens to halt crucial funding for disaster relief (including California's wildfire recovery), public health, education, and public safety programs. Bonta argues the directive violates the Constitution and the Administrative Procedure Act, and seeks a temporary restraining order to prevent immediate and irreparable harm.

Major Polar Vortex Disruption Imminent: Early End to Winter?

Major Polar Vortex Disruption Imminent: Early End to Winter?

For months, strong polar vortex winds have been circulating the stratospheric polar region. However, forecasts predict a major disruption this weekend, with wind speeds dramatically decreasing and potentially reversing. This could lead to a sudden stratospheric warming, with temperatures potentially rising 25°C in just days. This event may displace the polar vortex or split it, potentially impacting spring weather with colder-than-normal Arctic air. The extent to which this affects the troposphere remains uncertain. This could signal a premature end to the polar vortex season, a phenomenon observed in past years.

Training Large Diffusion Models on a Shoestring Budget: $1890

Sony Research has open-sourced micro_diffusion, demonstrating how to train large-scale diffusion models on an extremely low budget ($1890). Using 37 million publicly available real and synthetic images, they trained a 1.16 billion parameter sparse transformer model, achieving an FID score of 12.7 on zero-shot generation on the COCO dataset. The project provides training code, dataset code, pre-trained model weights, and details a staged training process, including progressive training from low to high resolution and the use of patch masking to reduce training costs and improve efficiency.

TrapC: A Safer C Extension

TrapC is a new extension of the C programming language designed to enhance memory safety. Removing keywords like `goto` and `union`, and adding `trap` and `alias`, TrapC incorporates C++ features such as constructors and destructors. It boasts automatic memory management, preventing leaks, and uses lifetime management for pointers instead of garbage collection. Despite its minimalist design—maintaining the same keyword count as C—it surprisingly offers significant C++ code compatibility. Presented at an ISO C meeting, TrapC aims to address memory safety concerns more comprehensively than other existing proposals.

Lisp Dialect Showdown: Scheme, Common Lisp, Clojure, and Racket

2025-03-07

The Lisp family is vast and complex. This post explores four prominent dialects: Scheme, Common Lisp, Clojure, and Racket. Scheme is known for its minimalism and strong academic foundation; Common Lisp boasts a rich standard library and decades of history; Clojure emphasizes functional programming, concurrency, and JVM interop; and Racket is beginner-friendly with a focus on education and extensibility. The article delves into each dialect's history, community, and unique characteristics, offering a humorous take on the inter-dialect 'tribalism'. Ultimately, it avoids declaring a 'best' dialect, instead guiding readers to choose the Lisp that best suits their needs.

Hello World: Minimized to 167 Bytes

This article documents the author's journey to create the smallest possible 'Hello World' program. Initially using Rust, the author discovered that minimizing the binary size required a deep dive into low-level programming. Ultimately, assembly language was chosen, and through clever techniques such as removing debugging symbols and manually crafting the ELF header, a 64-bit Linux 'Hello World' program was reduced to an impressive 167 bytes! The article delves into the file size expansion during the linking process and the details of the ELF file format, making it highly valuable for low-level system developers.

Typst vs. TeX: A Comparison of Layout Models and a Look Ahead

2025-02-14

This article explores the differences in layout models between the typesetting engines Typst and TeX. TeX, based on boxes and glue, is flexible but lacks awareness of precise positions; Typst uses a region model, allowing elements to react to their position but sacrificing some flexibility. The author analyzes the strengths and weaknesses of both models and points out that Typst, by introducing a re-layout mechanism, is expected to balance flexibility and optimization, addressing current shortcomings in handling complex layouts (such as wrap-around images and pageable tables).

Apple's Image Playground: A Case Study in AI Bias

Apple's new image generation app, Image Playground, despite incorporating safety features to prevent realistic deepfake generation, reveals inherent biases within AI models. Experiments show that using the same image with different prompts results in significant variations in skin tone and hair style, suggesting a bias towards certain skin colors. Further research highlights this bias is prevalent in other image generation models, reflecting societal biases embedded within training data. While Apple is addressing and attempting to measure model bias, completely resolving AI bias remains a significant challenge.
