Twenty-four years ago, surgeon Santiago Horgan performed the first robotically assisted gastric-bypass surgery, marking a significant medical advancement. Now, he is exploring the potential of Apple's Vision Pro mixed-reality headsets in the operating room. At the University of California, San Diego, Horgan and his colleagues have conducted over 20 minimally invasive surgeries using these headsets, which were released in February but have not performed well commercially. Horgan argues that the headsets can enhance surgical effectiveness and reduce

In "The Unaccountability Machine," Dan Davies discusses the concept of "accountability sinks," which are organizational structures that obscure or eliminate direct accountability for decisions made within a company. He illustrates this with an example of a hospitality company reducing its cleaning staff to improve financial metrics, resulting in customers experiencing service failures without a clear point of contact for complaints. Davies notes that for these accountability sinks to work, they effectively sever the link between the decision-makers and the consequences faced by those affected, preventing

In early 2022, the author acquired several Sun SPARC servers for free. Recently prompted for an update, they described an issue with the NVRAM (non-volatile RAM) in these machines, which holds BIOS configuration data. When powered off for extended periods, the NVRAM can lose its contents, especially as the internal battery degrades, leading to complete configuration wipes upon power cycles. Upon turning on the machines, the author encountered an error indicating that the NVRAM had been

As of April 26, 2023, there are 897 database options available, making it difficult to choose the right one. Historically, MySQL was favored in the 2000s, followed by MongoDB in the 2010s. In recent years, PostgreSQL has emerged as a popular choice due to its reliability and features. However, at OtterTune, the authors aim to address a significant flaw in PostgreSQL: its implementation of multi-version concurrency control (MVCC),

Choosing the right base image for a Node.js application can be complex due to the variations in size and security vulnerabilities (CVEs) among different Docker images. While the smallest image isn't always the best, there are several options to consider, such as the official Docker images, Bitnami's re-packaged image, and distroless options from Google and Chainguard. For production applications, Node.js recommends using LTS releases, specifically focusing on Node.js version 22 in this discussion. The

Sampling is a crucial method for analyzing large datasets by reducing them to smaller, representative samples that are easier to work with. SQL, a common query language, allows users to take samples from any dataset effectively. While many database systems have built-in sampling features, these may be limited to simpler cases. The article discusses a one-pass algorithm introduced by Pavlos S. Efraimidis and Paul G. Spirakis in 2006 for obtaining a weighted random sample from a population, which can be implemented

The content discusses strategies for file storage across \(N\) servers, highlighting the trade-offs between durability, fault tolerance, and storage efficiency. One approach is to replicate the entire file on each server, ensuring maximum durability but at the highest storage cost. Conversely, dividing the file into \(N\) chunks, with each server holding one chunk, offers better cost efficiency but requires all chunks for reconstruction. Erasure codes provide a balance between these extremes by allowing data to be divided into \(N\)
