Tesla Used Car Prices Plummet Amidst Growing Competition

The used car market is booming! Driven by historically high new car prices, consumers are flocking to the pre-owned market for better deals. Used Tesla Model Ys, in particular, have seen prices drop over $6,000 in the past year, with some low-mileage models available for under $30,000. Used Model 3s are even cheaper, with some high-mileage options dipping below $15,000. This trend is linked to the launch of new Tesla models, increased competition, and shifting consumer search preferences. A surge in rival EV manufacturers is giving consumers more choices, challenging Tesla's market dominance.

FTC Cracks Down on Hidden Fees: Transparency Mandate for Hotels, Tickets, and More

The US Federal Trade Commission (FTC) unveiled a new rule targeting deceptive fees, effective May 12th. This landmark regulation prohibits hidden charges for live events, hotels, and short-term rentals, banning practices like 'bait-and-switch' pricing. Businesses must clearly display the total price upfront, making it more prominent than other pricing details. While dynamic pricing is permitted, misleading information is strictly forbidden. The rule covers ticket sellers, lodging providers, and third-party platforms. The FTC provides guidance on which fees can be excluded (taxes, optional services), but these must be clearly disclosed. This is a significant victory for consumers long frustrated by hidden costs.

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.

LLMs: Lossy Encyclopedias

2025-09-02

Large language models (LLMs) are like lossy encyclopedias; they contain a vast amount of information, but this information is compressed, leading to data loss. The key is discerning which questions LLMs can answer effectively versus those where the lossiness significantly impacts accuracy. For example, asking an LLM to create a Zephyr project skeleton with specific configurations is a 'lossless' question requiring precise details, which LLMs struggle with. The solution is to provide a correct example, allowing the LLM to operate on existing facts rather than relying on potentially missing details within its knowledge base.

Superellipses and Superhyperbolas: Beyond Classical Geometry

2025-03-28

This article introduces superellipses and superhyperbolas, generalizations of ellipses and hyperbolas, respectively. The shapes are controlled by a parameter 'p'. When p=2, they reduce to standard ellipses and hyperbolas. Increasing p makes superellipses more rectangular, but with continuous curvature; superhyperbolas become blunted at the vertices. The article explores why superellipses are far more common than superhyperbolas, speculating on naming conventions and the lack of effective advocacy for the latter.
