Keyboard Company Halts US Shipments Due to Trump Tariffs

Mechanical keyboard company Qwertykeys has temporarily suspended all shipments to the US due to President Trump's tariffs on Chinese goods. The 45% tariff increase, coupled with DHL's new requirement for a 50% prepayment of declared value plus a $21 processing fee per package, makes shipping unsustainable. Qwertykeys is pausing shipments for 72 hours to negotiate with DHL and other logistics providers for fairer solutions. The company also faced temporary delays in sending replacement parts due to a now-reversed US Postal Service suspension of packages from China.

Record Seizure of Viagra-Laced ‘Erectile Honey’ in France

French customs officials announced a record seizure of illegally imported "erectile honey" laced with Viagra and other medications in 2024. The honey, primarily sourced from Turkey, North Africa, and Southeast Asia, is sold on the black market and in night shops as a natural sexual stimulant. However, it often contains hidden pharmaceuticals like sildenafil or tadalafil, the active ingredients in Viagra and Cialis, which can be dangerous when interacting with other medications, such as those for high blood pressure. A single seizure in Marseille last November confiscated 13 tons from Malaysia. The U.S. Food and Drug Administration (FDA) also issued warnings in 2021 and 2022 about honey-based supplements promising "sexual enhancement."

Lean 4.22: A New Verification Infrastructure for Imperative Programs

2025-07-07

Lean 4.22 introduces an exciting new feature: a new verification infrastructure for proving properties of imperative programs. The post uses a simple example—determining if a list contains two integers that sum to zero—to demonstrate the feature's use and compares it to similar tools like Dafny and Verus. The new framework, Std.Do, leverages Hoare triples and combines the `mvcgen` and `grind` tactics to greatly simplify the verification process for imperative programs, even those with complex control flow like loops and early returns. Unlike automated systems relying on external SMT solvers, Lean's interactive proving approach offers greater reliability, easier debugging, and better maintainability, making it a compelling choice for real-world program verification tasks.

Are All Clocks 30 Seconds Behind?

Are All Clocks 30 Seconds Behind?

The author proposes a seemingly crazy idea: all clocks are 30 seconds behind. This isn't about time zones, leap seconds, or relativity; it's about everyday clocks. Through calculation, the author shows that because most clocks only display minutes, ignoring seconds, the average error is 30 seconds. They argue that if clocks rounded instead of truncating, the average error would be 0. The author further explores how people perceive and express time at different scales (years, months, days, hours, minutes, seconds), noting that at the minute scale, intuition leans towards rounding, which conflicts with clocks' truncation. Therefore, they believe all clocks are 30 seconds slow.

Coder's Million-Dollar Mistake: A Bug with a Dramatic Twist

Trey, a programmer working for a 3G telecom startup, wrote an automated payment testing program intended for small test transactions. Three bugs in the code, however, caused the program to credit his test account with $100 every five minutes. A lack of liveness check meant that when one gateway failed, the program continued running for hours, accumulating a substantial sum. The next morning, Trey faced questioning from the security team until his department head explained the situation, but the test account balance was reset to zero.

The Chaotic Dance of Black Hole Singularities: The Return of the Mixmaster Universe

This article recounts the journey of physicists exploring the chaotic phenomena near black hole singularities. In the 1960s, Misner's "Mixmaster universe" model described the chaotic changes of space and time around singularities, but was shelved due to computational limitations. Recently, with new mathematical tools and increased computational power, scientists have revisited this model, attempting to unify general relativity and quantum mechanics by studying the extreme environment of singularities to ultimately reveal the nature of spacetime. Researchers utilize Maldacena's AdS/CFT correspondence to explore chaotic behavior near singularities in simplified models, hoping to prove that previous simplifying assumptions are valid and ultimately construct a theory of quantum gravity.
