Crystal Ball Challenge: Knowing the Future Isn't Enough to Guarantee Riches

Elm Partners conducted an experiment called the "Crystal Ball Challenge," where 118 finance students traded stocks and bonds using the Wall Street Journal's front page from one day in the future (with price data blacked out) over 15 days. The results were surprising: despite having future information, most participants didn't profit, averaging a mere 3.2% gain. Experienced traders, however, performed exceptionally well, averaging a 130% gain. The experiment demonstrated that even with 'future' knowledge, successful investing requires sensible position sizing. This research highlights the importance of decision-making under uncertainty and position sizing, offering valuable lessons for financial education.

A Faster Quantum Fourier Transform Algorithm

2025-01-27
A Faster Quantum Fourier Transform Algorithm

Ronit Shah presents an improved algorithm for the Quantum Fourier Transform (QFT). Traditionally, approximate QFT requires Θ(n log n) gates, and exact QFT requires Θ(n²) gates. The new algorithm, leveraging a novel recursive partitioning of qubits, reduces the cost of approximate QFT to Θ(n(log log n)²) gates and exact QFT to Θ(n(log n)²) gates. This breakthrough promises significant efficiency gains in quantum computation.

Camembert Cheese May Improve Cognitive Decline

A new study has found that fatty acid amides present in Camembert cheese can improve cognitive decline in mice. Researchers used the object recognition test and found that orally administered Camembert cheese improved cognitive decline induced by a high-fat diet. Further investigation revealed that myristamide (MA), a fatty acid amide produced during Camembert cheese fermentation, improved cognitive decline, while its non-amidated counterpart, myristic acid, did not. This suggests that fatty acid amidation may be crucial for this physiological activity. Furthermore, MA increased the expression of brain-derived neurotrophic factor (BDNF) in the hippocampus.

“Bread and Circuses”: Reframing the Narrative of Roman Decline

This article delves into the origins and meaning of the proverb “bread and circuses.” Tracing it back to Juvenal's satire, the author argues it's not a positive assessment of the Roman populace but a critique of their abdication of political responsibility in favor of basic needs and entertainment. The author challenges the common notion that “bread and circuses” caused Rome's downfall, attributing the decline to prolonged civil wars and instability, with the populace prioritizing peace above all else. Ultimately, the article reveals the true meaning of “bread and circuses”: a lament for the loss of political liberty and the constrained dreams of the Roman people.

Ken Thompson's Sneaky C Compiler Backdoor: A Reflection on Trust

2025-02-16

In his paper "Reflections on Trusting Trust," Ken Thompson, co-creator of UNIX, recounts a chilling tale of a self-replicating backdoor he inserted into the C compiler. This backdoor would automatically inject itself into the login program during compilation, granting him unauthorized access. The insidious part? Even removing the backdoor from the source code wouldn't stop the compiler from re-inserting it during compilation. This story serves as a stark reminder of the limitations of trusting software and the inherent difficulty in ensuring complete security, even with source code review.

GPUs Are So Fast, Why Do We Still Need CPUs?

A viral video uses a painting duel to illustrate the performance difference between CPUs and GPUs: a CPU painstakingly draws a smiley face, while a GPU instantly renders the Mona Lisa. But this overlooks a crucial point: program types. CPUs excel at sequential instructions, while GPUs thrive on parallel processing. Most applications blend sequential and parallel code; for example, a program might be 50% parallelizable. CPUs are like head chefs, adept at handling unexpected events; GPUs are like line cooks, mastering repetitive tasks. Chips like Apple's M3 integrate both, combining CPU flexibility with GPU computing power.

Preferring Throwaway Code Over Design Docs: A More Efficient Software Development Approach

In software development, the traditional design document and incremental development model isn't always efficient. Author Doug Turnbull proposes a "coding binge" approach: quickly implement a prototype using a temporary PR, get early team feedback, refine the design, and then gradually break it down into deployable PRs. This method encourages rapid iteration, early problem detection, and considers code itself as the best documentation. While design documents still have value in specific situations, the author advocates for "showing, not telling," using code prototypes for rapid validation and iteration to achieve more efficient software development.
