A watch is a small timepiece intended to be carried or worn by a person. It is designed to keep working despite the motions caused by the person's activities. A wristwatch is designed to be worn on a wrist, attached by a watch strap or other type of bracelet. A pocket watch is designed for a person to carry in a pocket.
Watches evolved in the 17thcentury from spring-powered clocks, which appeared as early as the 14thcentury. The first watches were strictly mechanical, driven by clockwork. As technology progressed, mechanical devices, used to control the speed of the watch, were largely superseded by vibrating quartz crystals that produce accurately timed electronic pulses. Some watches use radio clock technology to regularly correct the time. The first digital electronic watch was developed in 1970.
Most inexpensive and medium-priced watches, used mainly for timekeeping, are electronic watches with quartz movements. Expensive collectible watches, valued more for their elaborate craftsmanship, aesthetic appeal and glamorous design than for simple timekeeping, often have purely mechanical movements and are powered by springs, even though these movements are generally less accurate and more expensive than electronic ones. Various extra features, called "complications", such as moon-phase displays and the different types of tourbillon, are sometimes included. Modern watches often display the day, date, month and year, and electronic watches may have many other functions. Time-related features such as timers, chronographs and alarm functions are common. Some modern designs incorporate calculators, GPS and Bluetooth technology or have heart-rate monitoring capabilities. Watches incorporating GPS receivers use them not only to determine their position. They also receive and use time signals from the satellites, which make them essentially perfectly accurate timekeepers, even over long periods of time.
In software development, a breakpoint is an intentional stopping or pausing place in a program, put in place for debugging purposes. It is also sometimes simply referred to as a pause.
More generally, a breakpoint is a means of acquiring knowledge about a program during its execution. During the interruption, the programmer inspects the test environment (general purpose registers, memory, logs, files, etc.) to find out whether the program is functioning as expected. In practice, a breakpoint consists of one or more conditions that determine when a program's execution should be interrupted.
Breakpoints are most commonly used to interrupt a running program immediately before the execution of a programmer-specified instruction. This is often referred to as an instruction breakpoint.
Other kinds of conditions can also be used, such as the reading, writing, or modification of a specific location in an area of memory. This is often referred to as a conditional breakpoint, a data breakpoint, or a watchpoint.
Omaha (March 24, 1932 – April 24, 1959) was a United StatesThoroughbred horse racing champion. In a racing career which lasted from 1934 through 1936, he ran twenty-two times and won nine races. He had his greatest success as a three-year-old in 1935, when he won the Triple Crown. As a four-year-old, he had success running in England, where he narrowly lost the Ascot Gold Cup.
The horse was owned by and bred William Woodward, Sr.'s famous Belair Stud in Bowie, Maryland. He was trained by Sunny Jim Fitzsimmons, who also trained Omaha's sire to the Triple Crown. As a yearling, Omaha was leggy and awkward-looking but a favorite of Woodward, who reportedly considered sending the horse to England to be trained for the Epsom Derby. In the event, Omaha's move to England was postponed until 1936. He was ridden to his biggest wins by Canadian jockey Smokey Saunders.
