London Suburb Dweller's Megawatt-Hour Battery Dream

A London suburban resident attempts to calculate the battery size needed for complete home energy self-sufficiency. Using data from their solar panels (generating 3800 kWh annually, matching their consumption), and years of data analysis, they find a massive 1068 kWh (nearly a megawatt-hour) battery is required to store summer's excess energy for winter use. While currently unrealistic due to technology and cost, they remain optimistic about future battery technology advancements and price drops, envisioning a future where every home has such a battery, achieving complete solar self-sufficiency.

From Curiosity Cabinets to Public Museums: A Multi-Century Evolution

This article recounts the origin story of the modern museum, starting with the 17th-century craze among wealthy individuals for collecting curiosities in 'cabinets of curiosities'. It begins with a literary feud between poets Shadwell and Dryden, leading to a satirical portrayal of the 'virtuoso' Gimcrack, representing the obsessive collectors of the time. These private collections, initially driven by personal interests, gradually evolved into rigorously categorized scientific displays, ultimately transforming into publicly accessible museums like the Basel Kunstmuseum and the Ashmolean Museum, laying the foundation for our rich museum culture today.

Ghostly CVE: A Terminal Emulator Security Bug in Ghostty

2025-01-01

A new terminal emulator, Ghostty, recently released version 1.0. Security researcher David Leadbeater discovered a vulnerability (CVE-2024-56803) similar to a 2003 CVE, allowing attackers to execute arbitrary code by exploiting the terminal's title querying functionality. The vulnerability leverages the in-band signaling nature of terminals and Zsh's behavior in vi mode. Attackers can use crafted escape sequences to execute malicious commands without the user's knowledge, even over SSH. Ghostty 1.0.1 fixes this, users are advised to upgrade or apply mitigations provided in the advisory.

Context Engineering Strategies for Large Language Model Agents

2025-07-04

As large language model (LLM) agents gain traction, context engineering emerges as a crucial aspect of building efficient agents. This post summarizes four key context engineering strategies: writing (saving context outside the context window, such as using scratchpads or memories), selecting (choosing relevant context from external storage), compressing (summarizing or trimming context), and isolating (splitting context across multiple agents or environments). These strategies aim to address the limitations of LLM context windows, improve agent performance, and reduce costs. The post uses examples from companies like Anthropic and Cognition to detail the specific methods and challenges of each strategy, including memory selection, context summarization, and multi-agent coordination.

Cat Origin Story Rewritten: Tunisia, the Unexpected Cradle of Domestic Felines

Two large-scale studies are rewriting the history of domestic cat origins. By analyzing genetic data and archaeological evidence, researchers found that cats didn't accompany early farmers into Europe as previously thought. Instead, Tunisia is pinpointed as the origin point, with cats arriving in Europe in multiple waves starting around the 1st century CE. Religious and cultural factors played a crucial role, with the veneration of cats in ancient Egypt and their representation in Greco-Roman and Norse mythology driving their spread. The research also reveals competition and hybridization between domestic cats and native European wildcats, leading to a decline in wildcat populations. This discovery significantly alters our understanding of one of humanity's most familiar companions.

Tail Recursion: The Equivalence of Loops and Recursion

2025-08-12

This article delves into the equivalence of recursive functions and loops, focusing on tail-call optimization. Recursive functions are elegant and easy to reason about, but generally slower due to stack usage for intermediate results. Loops are faster but can be less readable. Tail recursion, where the recursive call is the last operation, allows compilers to optimize it into a loop, preventing stack overflow and improving performance. The article uses example code to compare recursive, iterative, and tail-recursive implementations of a summation function, and concludes with exercises to solidify understanding.

Regaining Sight: Stem Cell Transplants Repair Corneal Damage

A new clinical trial offers hope for patients with corneal injuries. Scientists have successfully repaired severe corneal damage using a transplant of stem cells from the patients' healthy eyes. The treatment, called cultivated autologous limbal epithelial cells (CALEC), involves harvesting stem cells from the patient's uninjured eye, culturing them in a lab for several weeks, and then transplanting them into the injured eye. An 18-month follow-up showed a 92% success rate, with significant vision improvement in many patients, some even progressing from legally blind to low vision.
