Bug (computing)
A software bug is an error, flaw or fault in the design, development, or operation of computer software that causes it to produce an incorrect or unexpected result, or to behave in unintended ways. The process of finding and correcting bugs is termed "debugging" and often uses formal techniques or tools to pinpoint bugs. Since the 1950s, some computer systems have been designed to deter, detect or auto-correct various computer bugs during operations. Bugs in software can arise from mistakes and errors made in interpreting and extracting users' requirements, planning a program's design, writing its source code, and from interaction with humans, hardware and programs, such as operating systems or libraries. A program with many, or serious, bugs is often described as ''buggy''. Bugs can trigger errors that may have ripple effects. The effects of bugs may be subtle, such as unintended text formatting, through to more obvious effects such as causing a program to crash, freezing th ...

Radiation Therapy
Radiation therapy or radiotherapy, often abbreviated RT, RTx, or XRT, is a therapy using ionizing radiation, generally provided as part of cancer treatment to control or kill malignant cells and normally delivered by a linear accelerator. Radiation therapy may be curative in a number of types of cancer if they are localized to one area of the body. It may also be used as part of adjuvant therapy, to prevent tumor recurrence after surgery to remove a primary malignant tumor (for example, early stages of breast cancer). Radiation therapy is synergistic with chemotherapy, and has been used before, during, and after chemotherapy in susceptible cancers. The subspecialty of oncology concerned with radiotherapy is called radiation oncology. A physician who practices in this subspecialty is a radiation oncologist. Radiation therapy is commonly applied to the cancerous tumor because of its ability to control cell growth. Ionizing radiation works by damaging the DNA of cancerous tis ...

Baffle Ball
''Baffle Ball'' is a pinball machine created in November 19, 1931 by David Gottlieb, founder of the Gottlieb amusement company. Gameplay For one US cent players get ten balls. These balls are fired up onto the playfield and fall into pockets and holes. Some ball targets are worth more than others, and players try to fire the ball at just the right speed. Unlike later pinball machines, ''Baffle Ball'' does not have flippers. The best target is the Baffle Ball, a tiny hole at the top which doubles all points. The game uses no electricity, and all scoring has to be done by hand. Description While bagatelle-derived "marble games" have long existed previously, ''Baffle Ball'' was the first commercially successful game of its type, being affordable enough for store and tavern owners to quickly recoup the machine's cost. Over 50,000 machines were made, jump-starting the arcade pinball field; it spawned a home version in 1932 called ''Baffle Ball Senior''.
