🌍 Geopolitics & Conflict

The U.S. Ammo Shortage Is Worse Than You Think

A recent conflict with Iran has underscored the U.S.’s critical shortage of ammunition needed to sustain a major war against adversaries like China. The current defense industrial base is insufficient to meet wartime demands, necessitating accelerated improvements in production and acquisition. Efforts to modernize the system, begun under the Trump administration, must be expanded to address broader strategic challenges and bolster munitions stockpiles.

Iran will close strait of Hormuz if Trump acts on 48 hour infrastructure threat

Iran’s IRGC warned that it will close the Strait of Hormuz if the U.S. targets Iranian energy facilities, responding to President Trump’s recent threat. This escalation follows attacks on Middle Eastern energy infrastructure and heightened tensions between the two countries. Closure of the strait would significantly disrupt global energy supplies and likely increase prices.

Curry controversy sparks debate

A recent analysis questions the widespread preference for currying in functional programming, arguing it doesn’t offer distinct advantages over alternative approaches like parameter lists or tuples. These methods can achieve the same partial application functionality, rendering currying theoretically equivalent and potentially unnecessary. The debate suggests the popularity of currying may stem from a misunderstanding of its capabilities.

Convincing Is Not Persuading

The article distinguishes between “convincing,” which relies on logic, and “persuading,” which involves understanding an audience’s motivations. Many technical proposals fail not because of technical issues, but because they focus on convincing rather than persuading decision-makers. Effective leaders recognize the importance of tailoring arguments to resonate with specific audiences and their unique circumstances.

Apple’s intentional crippling of Mobile Safari

A new comparison reveals that Apple’s Safari browser on iOS and iPadOS significantly lags behind Chrome for Android in supported web features.
