Summary: Automatic disk unlocking with TPM2 and systemd-cryptenroll/clevis can leave your system vulnerable to decryption by attackers with brief physical access. Most setups fail to verify LUKS identity, susceptible to filesystem confusion attacks. By exploiting real systems, attackers can mimic the original root filesystem, decrypt the partition, and introduce malicious software. One recommended solution involves […]

On its mission to the International Space Station, Dragon undergoes a series of precise maneuvers including burns to position itself closer to the station before docking. The process involves orbit activation, phasing burns to catch up with the ISS, and final approach and docking. The spacecraft performs these steps autonomously, establishing communication and navigation to […]
Every few months, people question why a particular DVLA service is turned off overnight. In the digital age, it seems strange for services to have limited hours. This post explains the complexities of government services being digitally native. DVLA had old technology from the 1980s, causing issues with overnight batch jobs. Despite challenges, new digital […]
Scientists and philosophers have long debated the meaning of life, with recent consensus that life requires the ability to reproduce and evolve through natural selection. Exploring the origins of life on Earth has revealed a possible solution involving RNA, which may have acted as both a protein enzyme and information carrier. The discovery that RNA […]
In this informative web content, the author delves into the complexities of memory management in software systems, with a focus on Rust’s restrictive memory model. Highlighting the differences between storing data in memory in C and more dynamic languages like Python, the author emphasizes the importance of memory allocation for variable-sized objects using concepts like […]
In May of 1694, Isaac Newton and David Gregory stumbled upon a math puzzle while contemplating stars’ orbits around a central sun. The problem, known as the “kissing problem,” involves arranging spheres around a central one without overlapping. While the maximum “kissing number” in three dimensions is 12, it varies in other dimensions, and recent […]
In 2019, construction workers in Spain discovered a Roman tomb sealed for two thousand years under an old house, where they found a glass urn with cremated remains and five liters of mysterious red liquid – the oldest wine ever found, dated back to the first century CE. The preservation of the tomb, its painted […]
The author discusses the negative impact of excessive social media scrolling on mental health but highlights the occasional valuable content that makes it worthwhile. They introduce a solution in the form of RSS technology, which filters out noise from platforms like Reddit, Facebook, and Twitter. By subscribing to specific websites, one can customize their feed […]
In this blog post, the author discusses the integration of AI-autocompleted code and Test-Driven Development (TDD) using Large Language Models (LLMs). Despite the skepticism around using AI in software development, the author believes that LLMs have changed the economics of TDD. The author shares a unique workflow where they automate the back-and-forth copy-pasting process between […]
A new research breakthrough at Stanford University and King Fahd University of Petroleum and Minerals has developed a way to generate ammonia from the atmosphere without requiring an external power source. Ammonia is a key component of fertilizer and has recently gained attention as a sustainable fuel source for hydrogen production. The innovative technique uses […]
