Compound actions on shared state, such as incrementing a hit counter (read-modify-write) or lazy initialization (check-then-act), must be made atomic to avoid race conditions. Holding a lock for the entire duration of a compound action can make that compound action atomic. However, just wrapping the compound action with a synchronized block is not sufficient; if synchronization is used to coordinate access to a variable, it is needed everywhere that variable is accessed. Further, when using locks to coordinate access to a variable, the same lock must be used wherever that variable is accessed. ↗

Accessing shared, mutable data requires using synchronization; one way to avoid this requirement is to not share. If data is only accessed from a single thread, no synchronization is needed. This technique, thread confinement, is one of the simplest ways to achieve thread safety. When an object is confined to a thread, such usage is automatically thread-safe even if the confined object itself is not. ↗

Michael Jordan and Magic and myself all learned how to play the game in college programs that emphasized the team. ↗

I often get letters, quite frequently, from people who say how they like the programmes a lot, but I never give credit to the almighty power that created nature. ↗

You can only get really unpopular decisions through if the electorate is convinced of the value of the environment. That's what natural history programmes should be for. ↗

I am very much against weapons in space. And I wish we could be spearheading that program to come to some kind of international agreement so that doesn't happen. That is my only - fear - in further space exploration like always, we hope it doesn't get abused. ↗

When I was 17, I worked in a mentoring program in Harlem designed to improve the community. That's when I first gained an appreciation of the Harlem Renaissance, a time when African-Americans rose to prominence in American culture. For the first time, they were taken seriously as artists, musicians, writers, athletes, and as political thinkers. ↗

Once an object escapes, you have to assume that another class or thread may, maliciously or carelessly, misuse it. This is a compelling reason to use encapsulation: it makes it practical to analyze programs for correctness and harder to violate design constraints accidentally. ↗
