Southern boobook their upperparts. The tips of their feathers are white and fluffy, remnants of the nestlings' down. These are worn away over time, persisting longest on the head. The feathers of the head, neck and underparts are fluffier overall. Immatures in their second and third year have plumage more like adults, though their crowns are paler and more heavily streaked. On mainland Australia, it could be confused with the barking owl or the brown hawk-owl ("Ninox scutulata"), a rare vagrant to the northwest, although the southern boobook is easily distinguished by its squat posture and distinctive pale border to its face
Programming in the large and programming in the small Programming-in-the-Small", IEEE Trans. on Soft. Eng. 2(2). In computer science terms, "programming in the large" can refer to programming code that represents the high-level state transition logic of a system. This logic encodes information such as when to wait for messages, when to send messages, when to compensate for failed non-ACID transactions, etc. A language that was designed to explicitly support programming in the large is BPEL. In software development, programming in the small describes the activity of writing a small program. Small programs are typified by being small in terms of their source code size, are easy to specify,
