In the early 1943 wartime letter to Oswald Veblen, mathematician John von Neumann expressed his fascination with experimental physics and computational techniques, later proving to be a crucial aspect in the development of computing and nuclear weapons. Von Neumann’s rapid contributions across various fields, including economics and computer science, solidified his place as a 20th-century […]

PumpkinOS is a unique re-implementation of PalmOS that runs on modern architectures like x86 and ARM without requiring a PalmOS ROM. It can run m68K PalmOS applications like AddressBook, MemoPad, ToDoList, and DateBook with some compatibility issues. This project is still experimental, with the goal of providing a glimpse into the future of PumpkinOS. The […]
On May 29, 2023, the LIGO Livingston detector observed a signal from the merger of a neutron star and an unknown compact object, potentially a lightweight black hole. This discovery challenges the previously accepted mass gap between neutron stars and black holes. The researchers at the Max Planck Institute for Gravitational Physics played a crucial […]
ElephantSQL will be discontinued on January 27, 2025. The company will shift focus to AMQP protocol via CloudAMQP, specifically RabbitMQ and LavinMQ. Existing customers will have access until the close date. New users will not be accepted after May 1, 2024. An action plan and contact information are available for customers. The team will join […]
Minnesota-based 3M will begin payments to U.S. public drinking water systems due to contamination by potentially dangerous chemicals, impacting communities in the east metro. The multi-billion-dollar settlement received final approval from a U.S. District Court in South Carolina, with payouts scheduled through 2036. The settlement compensates for pollution caused by PFAS chemicals, known as “forever […]
ClangQL is a tool that allows SQL-like queries on C/C++ code using the GitQL SDK. It is case-insensitive, similar to SQL. You can query functions with various conditions like return type or argument count. To use ClangQL, download from Cargo.io or build from source. Run it on local files with options like pagination, output format, […]
Welcome to opt-models! This web content delves into building large-scale optimization models with a focus on speed and modern deployment. The author introduces a video series on creating mathematical optimization models in AMPL, using solvers like Gurobi and CPLEX, deploying models as containerized applications, and more. Discussions take place on the Maven platform, where AI […]
The author explores the realm of frequency domains, challenging the dominance of the Fourier transform with the Walsh-Hadamard transform. Contrary to the traditional approach of deconstructing signals into sine harmonics, the Walsh-Hadamard transform dissects data into square waves through a matrix of +1s and -1s. The detailed explanation covers the construction of the Walsh matrix […]
Apple has been at the forefront of great design trends over the years, including the popularization of progressive blur in their designs. This unique effect increases readability by reducing the frequency of background colors, making text easier to read. While blur is not a new concept, implementing progressive blur on the web proved to be […]
In the free excerpt from Lectures on the Philosophy of Mathematics, published by MIT Press in 2021, the author introduces the philosophy of mathematics grounded in mathematical inquiry and practice. Discussing Dedekind’s categoricity result for arithmetic and structuralism, the text delves into the philosophy that emphasizes the importance of isomorphism-invariance in math. The structuralism idea […]
