TL;DR summary of stories on the internet
The author shares their experience with a card testing attack that their company faced. They initially implemented Stripe Radar and added captcha to their checkout process to address the issue. However, they later discovered that the attackers were manually or lightly automating the attacks, using a list of cards with similar parameters. The author suspects […]

This web content is a manifesto on the use of code as an alternative to mathematics to understand and apply Kalman filters. The author provides an accessible explanation of Kalman filters, describing them as a means of combining multiple imperfect and unreliable sources of information to estimate a more accurate statistic. The content includes code […]
In this web content, the author discusses the use of Bayes factors in testing hypotheses. The author presents a scenario where a minimum wage increase of $4 leads to a 1% increase in unemployment. The author explains that Bayes factors compare the data with both the null hypothesis and alternative hypotheses. They argue that Bayes […]
The Pixel Pump, created by Robin Reiter, is an open source manual pick & place assist tool that is now available for shipping. This project, initially entered into the 2021 Hackaday Prize, caught our attention due to its sleek design and the idea of an open architecture for a tool that is essential for desktop […]
Security researchers have found over 200,000 stolen OpenAI credentials for sale on the dark web. These compromised credentials give buyers access to ChatGPT’s premium features and chats containing confidential information like trade secrets and business plans. The stolen credentials were obtained through various malware variants, with the Asia-Pacific region having the highest number of OpenAI […]
In this paper, the authors discuss the pursuit of room-temperature superconductivity, which has long been a goal in the fields of solid-state physics and materials science. They highlight the potential revolutionary impact of achieving this, as it could lead to significant changes in energy transmission and storage. The authors turn their attention to recent research […]
The author reflects on a past idea of a “desert island machine” where someone is placed in a room with minimal resources and challenged to build a functioning system from scratch. They entertain the idea of “speedrunning” the Linux situation, starting with a minimal system and quickly progressing to accomplish meaningful tasks. The author predicts […]
Enu is a 3D live coding system implemented in Nim. It aims to make 3D development more accessible and is designed to be usable by younger people who may struggle with reading or typing. Enu uses a block-building interface and a Logo-inspired API to allow users to build and explore worlds. The documentation for Enu […]
The author of this web content shares their method of creating a “personal” virtual machine to use alongside their work laptop. They install a virtualization system and use a “Server” version of Ubuntu, with Emacs as their window manager. They explain that this setup allows them to split the screen into windows, launch programs, and […]
In a recent study by Lee et al., published in the Journal of Korean Crystal Growth and Crystal Technology, some interesting findings suggest that Pb$_{10-x}$Cu$_x$(PO$_4$)$_6$O, also known as LK-99, could potentially be a room-temperature superconductor at normal atmospheric pressure. The authors conducted density-functional theory calculations, which revealed similar lattice parameters and a volume contraction with […]
