Wisdom I Pondered This Week

Things I Learned This Week

  • The SR-71 Blackbird was a strategic reconnaissance aircraft for the U.S. Air Force in the 1960s. Capable of Mach 3.2+ speeds, altitudes above 85,000 ft, and a range of ~3,200 nautical miles, it could outrun surface-to-air missiles and was never shot down. In service from 1966 to 1998, it became a Cold War icon, nicknamed the Habu, and still holds the official speed record for a manned, air-breathing aircraft.
  • A Code Freeze, also known as a feature freeze or a hard freeze, is a designated period in software development during which no new code changes or modifications are introduced to the codebase. Its primary goal is to stabilize the codebase in preparation for a major release or other milestone. During this time, developers shift their focus from implementing features to testing and debugging, ensuring that the software remains stable, reliable, and production-ready.
  • Ligatures are when two or more characters are joined into a single symbol for improved aesthetics, readability, or style, originating from traditional typography (e.g., ”fi“, ”fl“) to prevent awkward letter collisions in printing. In modern digital fonts, they are a design choice, used in normal fonts for polished text and in programming fonts (like Fira Code) to visually join sequences such as != or -\>. The transformation is purely a visual effect — the underlying characters remain unchanged. Ligatures just make certain patterns look cleaner or easier to read.
  • The Bar Exam (律師資格考試) is a professional licensure test required to legally practice law in a given jurisdiction. Its purpose is to assess whether a candidate possesses the necessary legal knowledge, reasoning ability, and ethical standards to serve competently as a lawyer.
  • Ground Meat (絞肉), also known as minced meat, is finely chopped meat commonly made from beef, pork, lamb, chicken, turkey, or plant-based alternatives like soy or pea protein. It’s prized for its versatility and quick cooking time, making it a staple in dishes such as hamburgers, meatballs, tacos, Bolognese, and meatloaf. The fat content varies by blend (e.g., 80/20 or 90/10), affecting juiciness and flavor—higher fat yields richer taste, while leaner meat is healthier but can be drier. For safety, ground beef, pork, and lamb should be cooked to 71°C (160°F), and ground poultry to 74°C (165°F), as bacteria can be distributed throughout during processing.
