Dieppe Raid: A Costly Failure?

This account recounts the disastrous Dieppe Raid of 1942. Over 5000 Allied soldiers participated, suffering heavy casualties with at least 2000 killed or captured. While the RAF inflicted significant damage on German fighters, the raid itself was a failure, achieving minimal strategic objectives and resulting in substantial Allied losses. The text explores potential reasons for the failure, including German advance knowledge and deficiencies in Allied fire support and landing plans. The debacle underscored the immense challenges of a European invasion and provided crucial lessons for future amphibious operations.

Go's io.Reader Efficiency: A Battle with Indirection and Type Assertions

2025-05-19

Many Go functions take an io.Reader, enabling streaming and avoiding loading everything into memory. However, when you already have the bytes, using them directly is more efficient. This article describes the author's experience decoding images with libavif and libheif. For simplicity, the simple memory interfaces were used, but the Go image.Decode function checks for a Peek function on the io.Reader, wrapping with bufio.Reader if not found, preventing direct use of bytes.Reader. The author cleverly uses type assertions and unsafe.Pointer to bypass bufio.Reader and bytes.Reader, achieving zero-copy. However, the article highlights issues in Go's type checking and interface design, including the resulting 'shadow APIs'.

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.

Unique Games Conjecture: A Surprisingly Divisive Problem in Computational Complexity

2025-05-10

Proposed by Subhash Khot in 2002, the Unique Games Conjecture (UGC) posits that approximating the value of a specific type of game, known as a unique game, is NP-hard. This conjecture has significant implications for the theory of approximation algorithms; if true and P≠NP, many crucial problems wouldn't allow for good polynomial-time approximations, not just exact solutions. The academic community is split on its validity, with equivalent formulations including label cover and Max2Lin(k) problems. While stronger versions have been disproven, the UGC's exploration has spurred substantial mathematical research, and some progress towards proving it has been made, including proving a related conjecture, the 2-2 games conjecture.

California Broadband Bill Sparks Debate: Protecting Renters or Stifling Competition?

A California bill (AB 1414) aimed at lowering broadband costs for renters has sparked controversy. Groups like the Real Estate Technology & Transformation Center (RETTC) oppose the bill, arguing it will raise costs, reduce investment, and widen the digital divide. They claim the bill's opt-out requirement will undermine the economics of bulk billing. However, supporters argue it promotes competition, particularly benefiting wireless or satellite providers as it avoids the need for wiring each building. While the bill may lower broadband costs for renters, a previous California bill pushing for significantly cheaper broadband plans was shelved after the Trump administration threatened to block broadband expansion funding.

Nagel on Moral Judgment and Progress: A Critique

This article examines Thomas Nagel's views on the objectivity of moral judgment and moral progress. Using the anecdote of a WWII French Resistance member interrogating a Nazi collaborator, Nagel illustrates the power of moral intuitions. While acknowledging utilitarian and evolutionary explanations for these intuitions, he argues they reflect underlying moral truths. Nagel distinguishes scientific from moral progress, asserting that accessing moral truths depends on historical developments revealing new moral reasons. He uses examples like individual rights, social equality, sexual morality, and international justice to show moral progress stems from multiple factors, not a single principle. The author ultimately questions Nagel's view, suggesting applying utilitarian principles to all affected individuals is key to moral advancement.

Tracing JITs in PyPy: A Pragmatic Choice?

2025-01-10

This post delves into the advantages and disadvantages of tracing JIT compilers, specifically focusing on their implementation within PyPy. Tracing JITs, which generate code by tracing program execution, offer benefits when handling complex languages like Python, effectively slicing through layers of abstraction and reducing overhead. However, they also suffer from performance instability and edge cases. Based on two decades of experience with PyPy, the author provides a nuanced analysis of tracing JITs' suitability, comparing them to method-based JITs. The conclusion suggests that, within PyPy's meta-JIT context and given its resource constraints, tracing remains a relatively pragmatic approach.
