Victorian London's Cat's Meat Men: A Portrait of Hard Work

During Queen Victoria's reign, London's cat's meat men, with their blue aprons, black hats, and corduroy trousers, became a subject of anthropological investigation by journalists. Henry Mayhew's *London Labour and the London Poor* (1851) delves into their visible yet mysterious world. Mayhew estimated a thousand such traders serving around 300,000 cats. While seemingly lucrative, Mayhew's interviews revealed a life of grueling labor. One carrier reported walking 30 to 40 miles daily through London's streets.

MVVM in SwiftUI: Best Practices and Pitfalls

This article delves into the best practices and challenges of using the Model-View-ViewModel (MVVM) architectural pattern in SwiftUI. The author argues that while MVVM aligns well with SwiftUI's data flow, its perceived rigidity can introduce problems. The article explains how MVVM works, how to leverage its advantages in SwiftUI, and how to navigate its challenges, including avoiding overusing view models and implementing MVVM in a SwiftUI app. It also compares MVVM to alternative architectural patterns like MVC, the Model-View pattern, and Clean Architecture, analyzing their pros and cons.

Caffeine: A Cellular Fountain of Youth?

Caffeine: A Cellular Fountain of Youth?

Researchers at Queen Mary University of London have uncovered a new mechanism by which caffeine might slow cellular aging. Their study, using fission yeast, demonstrates that caffeine activates AMPK, a cellular energy sensor conserved in yeast and humans, rather than directly influencing the TOR pathway. By activating AMPK, caffeine influences cell growth, DNA repair, and stress response – all factors implicated in aging and disease. This research offers a novel explanation for caffeine's potential health benefits and opens avenues for exploring how to more directly trigger these effects through diet, lifestyle changes, or novel medications.

DragonFlyBSD's Next-Gen Disk Encryption: dm_target_crypt_ng

2025-04-13

DragonFlyBSD has a major update: dm_target_crypt_ng, a next-generation disk encryption implementation. Developer Michael Neumann re-engineered the DM-crypt code for improved performance and interactivity. The new version ditches opencrypto and cryptodev, opting for a simplified symmetric block cipher API and using two worker pools for efficiency. Currently supporting AES-CBC and AES-XTS, with plans to add Twofish and Serpent. This update significantly improves system responsiveness, providing a smoother disk encryption experience for DragonFlyBSD users. It's expected to become the default in the upcoming DragonFlyBSD 6.4 release.

The Facebook 2014 Outage: Why 'War Rooms' Are Bad for Deep Investigation

2025-02-23

The author recounts the epic Facebook outage of August 1st, 2014, dubbed "Call the Cops." Working in a cramped, overheated 'war room', the author found it impossible to effectively troubleshoot the root cause. He ultimately retreated to his own comfortable workspace. After 18 days of investigation, he pinpointed the problem: a process called 'fbagent' incorrectly sent a termination signal to all processes, leading to system failure. This experience highlights the importance of providing a suitable personal work environment during emergencies and emphasizes the value of in-depth investigation over rapid fixes.

Local LLM Inference: Potential is Huge, But Tooling Needs to Mature

Local LLM Inference: Potential is Huge, But Tooling Needs to Mature

This article benchmarks the performance of local LLM inference frameworks such as llama.cpp, Ollama, and WebLLM. Results show llama.cpp and Ollama are blazing fast, but still slower than OpenAI's gpt-4.0-mini. A bigger challenge lies in model selection and deployment: the sheer number of model versions is overwhelming, and even a quantized 7B model is over 5GB, leading to slow downloads and loading, impacting user experience. The author argues that future local LLM inference needs easier model training and deployment tools, and tight integration with cloud LLMs, to become truly practical.

Apple Found in Contempt of Court, Ordered to Halt App Store Commission

A federal judge ruled that Apple Inc. violated a court order and must stop charging commissions on purchases outside its App Store. Judge Yvonne Gonzalez Rogers found Apple willfully defied a 2021 ruling that required it to allow developers to bypass its in-app payment system. The judge also referred the case to federal prosecutors to investigate possible criminal contempt of court. This decision could significantly impact Apple's billions of dollars in annual App Store revenue and potentially lead to further legal battles. Epic Games, the plaintiff in the case, celebrated the ruling as a victory for developers.

Amazon's AI Talent Woes: Frugality and RTO Policies Hamper Recruitment

Amazon is lagging in the fierce AI talent war. Internal documents reveal that its unique pay structure, lagging AI reputation, and rigid return-to-office (RTO) policies are major obstacles. Competitors offer more competitive compensation and flexible work arrangements, making it difficult for Amazon to attract top talent. While Amazon claims its compensation is competitive, its 'egalitarian' pay philosophy and strict salary bands hinder its ability to compete for high-earning AI experts. The mandatory RTO policy further limits its access to talent. Amazon is trying to adjust its recruitment strategy, but whether its ingrained frugal culture and rigid systems can change remains to be seen.

US to Stop Making Pennies: A Costly Tradition Bites the Dust

US to Stop Making Pennies: A Costly Tradition Bites the Dust

The US Treasury is phasing out the penny. Production of new one-cent coins will cease once existing blanks are used up. This move, driven by the fact that producing a penny costs over three cents, follows President Trump's earlier order to halt production. While consumers can still use existing pennies, businesses will round cash transactions to the nearest nickel. The Treasury estimates $56 million in annual savings, but increased nickel demand might offset this. This echoes Canada's previous elimination of the penny, highlighting a trend towards efficiency and waste reduction.

This article recounts a little-known speech given by Albert Einstein at the 1940 New York World's Fair. The speech praised the contributions of immigrants and African Americans, advocating for the acknowledgment of America's diversity and inclusivity. The context is set against the backdrop of pre-WWII anti-immigrant sentiment and Nazi influence in the US; Einstein's speech served as a powerful counterpoint, emphasizing the importance of multiculturalism to American society and refuting the fallacies of immigration restriction. This contrasts sharply with the nativist movements of the 1850s and the pro-Nazi elements before WWII.

The author received a challenging 3D puzzle consisting of 25 identical wooden pieces and, after struggling to solve it manually, decided to leverage the power of the Haskell programming language. This is the first of a two-part series focusing on modeling the problem. The author models the space as a 3D grid, using vectors to represent positions and defining data structures for a single piece and its arrangement in space. The article details how linear algebra and Haskell features are used to represent rotations and translations of the pieces, generating a candidate list of all possible arrangements. The article ends with a cliffhanger, leaving the solution of finding the correct arrangement from the candidates to the second part.

P vs. PSPACE: Is Space Computationally More Powerful Than Time?

A central question in complexity theory is the relationship between the complexity classes P and PSPACE. P encompasses problems solvable in reasonable time, while PSPACE deals with space complexity. The prevailing belief is that PSPACE is larger than P, due to space's reusability unlike time. Proving this requires demonstrating problems in PSPACE unsolvable in polynomial time. The article recounts the 1975 breakthrough by Hopcroft, Paul, and Valiant, showing space's slight advantage over time, but progress stalled. Ryan Williams' work finally broke the deadlock, offering fresh insights into resolving the P vs. PSPACE problem.

Generative AI: A Paradigm Shift in Programming

Large Language Models (LLMs) are revolutionizing software development, a change comparable to the shift from assembly language to high-level programming languages. The author argues that LLMs not only raise the level of abstraction but also introduce non-determinism, fundamentally altering the nature of programming. The evolution from Fortran to Ruby improved efficiency but didn't change the core essence of programming. The non-determinism introduced by LLMs requires programmers to adapt, presenting both challenges and opportunities.
