Erik Naggum explains the importance of the ‘pair’ notion in Scheme, highlighting the success of the abstract data type (ADT). He criticizes the simplistic view and flawed implementations in other languages, praising the brilliance and complexity of Lisp’s ‘list’ ADT. Naggum delves into the historical background behind the ‘cons cell’ and the significance of ‘car’ […]

Summary: The IRS announced the expansion of Direct File, a free e-filing service, to 24 states for the 2025 tax season, doubling from last year. The service will now cover a wider range of tax situations, including interest income, retirement income, and various tax credits. Users can access Direct File on various devices and receive […]
The content discusses scaling pipelines using RxJS and Go for processing images. It outlines how to reuse decoders efficiently, handle errors when processing images, and prevent goroutines from being cancelled prematurely. A bug causing the program to fail in specific scenarios is highlighted. While RxJS handles completion differently from Go, the issue can be resolved […]
The author expresses admiration for working in Linux despite its flaws, emphasizing its programmability and synergy with various languages. They highlight the simplicity and flexibility of text streams and the universal data structure in Unix. The author critiques Unix for its outdated features like the archaic file system and the limited capabilities of the terminal […]
In recent years, there has been a renewed interest in traditional recurrent neural networks (RNNs) like LSTMs and GRUs due to the scalability limitations of Transformers. By removing hidden state dependencies from these models, researchers have found they can be trained in parallel without the need for backpropagation through time (BPTT). This has led to […]

This surprising message is present in various Linux distributions like RHEL, OpenSUSE, Fedora, and Debian. The code responsible for this output was added […]
Robert Dennard, known for inventing Dynamic RAM, transformed the computer industry by developing a memory cell that utilized a tiny capacitor and transistor. His groundbreaking invention made RAM less expensive and more accessible. Dennard’s work on transistors also led to the development of low-power, high-performance integrated circuits. His theory known as Dennard scaling revolutionized the […]
NASA satellites initially built to detect high-energy particles from space were surprised to find high-energy gamma radiation bursts coming from thunderstorms on Earth. After years of uncertainty, a team of scientists used a retrofitted U2 spy plane to study these phenomena and discovered that gamma radiation in thunderstorms is much more common than previously thought. […]
Permiso Security researchers recently discovered a disturbing trend involving stolen cloud credentials used for illicit sex chat services that may involve child sexual exploitation and rape. These attackers target organizations with exposed credentials, particularly on AWS Bedrock, to bypass content restrictions and hijack the infrastructure for profitable sexual services. Surprisingly, Permiso researchers attempted a unique […]
