"The Licensing Racket," by Philip Hamburger, exposes the pervasive and often absurd world of occupational licensing in America. Hamburger argues that these boards, ostensibly designed to protect the public, frequently serve as protectionist barriers for existing practitioners, stifling competition and harming consumers with higher prices and reduced access to services. He details the often arbitrary and onerous requirements imposed on aspiring professionals, from florists and interior designers to fortune tellers, illustrating how these regulations disproportionately impact lower-income individuals seeking economic advancement. The book ultimately calls for a reassessment of the necessity and scope of occupational licensing, advocating for deregulation and a return to more open markets.
Hacker News users generally agree with the premise of the WSJ article, lamenting the excessive licensing requirements across various professions. Several commenters share personal anecdotes of burdensome and seemingly pointless licensing procedures. Some highlight the anti-competitive nature of these boards, suggesting they serve primarily to protect established professionals and inflate prices. Others point to the variability of licensing requirements across states as further evidence of their arbitrary nature. A few commenters discuss potential solutions, including deregulation and national reciprocity agreements, while acknowledging the difficulty of implementing meaningful reform. The discussion also touches upon the historical context of licensing, with some suggesting it originated as a way to ensure quality and protect consumers, but has since morphed into a protectionist racket.
The blog post explores visualizing the "ISBN space" by treating ISBN-13s as coordinates in 13-dimensional space and projecting them down to 2D using dimensionality reduction techniques like t-SNE and UMAP. The author uses a dataset of over 20 million book records from Open Library, coloring the resulting visualizations by publication year or language. The resulting scatter plots reveal interesting clusters, suggesting that ISBNs, despite being assigned sequentially, exhibit some grouping based on book characteristics. The visualizations also highlight the limitations of these dimensionality reduction methods, as some seemingly close points in the 2D projection are actually quite distant in the original 13-dimensional space.
Commenters on Hacker News largely praised the visualization and the author's approach to exploring the ISBN dataset. Several pointed out interesting patterns revealed by the visualization, such as the clustering of books by language and subject matter. Some discussed the limitations of using ISBNs for this kind of analysis, noting that not all books have ISBNs (especially older ones) and the system itself has undergone changes over time. Others offered suggestions for improvements or further exploration, such as incorporating data about book sales or using different dimensionality reduction techniques. A few commenters shared related projects or resources, including visualizations of other datasets and tools for working with ISBNs. The overall sentiment was one of appreciation for the project and its insightful presentation of complex data.

A few users shared their personal book recommendation methods, contrasting them with the tool's approach. The creator responded to many comments, acknowledging the suggestions and explaining some design choices.
A new algorithm for the "pancake sorting problem" — sorting a disordered stack by repeatedly flipping sections of it — has achieved near-optimal efficiency. While the minimal number of flips required to sort any stack remains unknown, the new algorithm, developed by researchers at MIT and other institutions, guarantees completion within 1.375 times the theoretical minimum. This represents a significant improvement over previous algorithms, edging closer to a perfect solution for a problem that has puzzled computer scientists for decades. The researchers employed a recursive strategy that breaks down large stacks into smaller, more manageable substacks, optimizing the flipping process and setting a new benchmark for pancake sorting efficiency.
Hacker News users discussed the practicality and significance of the new book-sorting algorithm. Some questioned the real-world applicability given the specialized constraints, like pre-sorted sections and a single robot arm. Others debated the definition of "perfection" in sorting, pointing out that minimizing the arm's travel distance might not be the only relevant metric. The algorithm's novelty and mathematical elegance were acknowledged, but skepticism remained about its potential impact beyond theoretical computer science. Several commenters highlighted the existing highly optimized solutions for real-world sorting problems and suggested that this new algorithm is more of an interesting theoretical exercise than a practical breakthrough. There was also discussion about the difference between this algorithm and existing techniques like Timsort, with some arguing the new algorithm addresses a distinctly different problem.
Agnes Callard's Open Socrates offers a practical philosophy focused on "aspiring." Callard argues that we should actively strive for values we don't yet hold, embracing the difficult process of becoming the kind of person who embodies them. The book explores this through engaging with figures like Socrates and Plato, emphasizing the importance of self-creation and the pursuit of a life guided by reason and critical thinking. While not providing easy answers, it encourages readers to confront their own limitations and actively work towards a better version of themselves.
HN commenters generally express interest in Callard's approach to philosophy as a way of life, rather than just an academic pursuit. Several praise the reviewer's clear explanation of Callard's "aspirational" philosophy. Some discuss their own experiences with transformational learning and self-improvement, echoing Callard's emphasis on actively striving for a better self. A few express skepticism about the practicality or accessibility of her methods, questioning whether her approach is truly novel or simply repackaged ancient wisdom. Others are intrigued by the concept of "proleptic reasons," where present actions are justified by a future, hoped-for self. Overall, the comments reflect a mix of curiosity, cautious optimism, and some doubt regarding the applicability of Callard's philosophical framework.
