A screensaver is a computer program that blanks the screen or fills it with moving images or patterns when the computer has been idle for a long time. The original purpose of screensavers was to prevent phosphor burn-in on CRT and plasma computer monitors. Though modern monitors are not susceptible to this issue, screensavers are still used for other purposes. Screensavers are set up to offer a basic layer of security, by requiring a password to re-access the device; some screensavers use the otherwise unused computer resources to do useful work, such as processing for distributed computing projects. As well as computers, modern television operating systems, media players and other digital entertainment systems include optional screensavers. Before the advent of LCD screens, most computer screens were based on cathode ray tubes; when the same image is displayed on a CRT screen for long periods, the properties of the exposed areas of phosphor coating on the inside of the screen and permanently change leading to a darkened shadow or "ghost" image on the screen, called a screen burn-in.
Cathode ray televisions and other devices that use CRTs are all susceptible to phosphor burn-in, as are plasma displays to some extent. Screen-saver programs were designed to help avoid these effects by automatically changing the images on the screen during periods of user inactivity. For CRTs used in public, such as ATMs and railway ticketing machines, the risk of burn-in is high because a stand-by display is shown whenever the machine is not in use. Older machines designed without burn-in problems taken into consideration display evidence of screen damage, with images or text such as "Please insert your card" visible when the display changes while the machine is in use. Blanking the screen is out of the question as the machine would appear to be out of service. In these applications, burn-in can be prevented by shifting the position of the display contents every few seconds, or by having a number of different images that are changed regularly. CRTs were much less susceptible to burn-in than older models due to improvements in phosphor coatings, because modern computer images are lower contrast than the stark green- or white-on-black text and graphics of earlier machines.
LCD computer monitors, including the display panels used in laptop computers, are not susceptible to burn-in because the image is not directly produced by phosphors. While modern screens are not susceptible to the issues discussed above, screensavers are still used; these are for decorative/entertainment purposes, or for password protection. They feature moving images or patterns and sometimes sound effects; as screensavers are expected to activate when users are away from their machines, many screensavers can be configured to ask users for a password before permitting the user to resume work. This is a basic security measure against another person accessing the machine while the user is absent; some screensavers activate a useful background task, such as a virus scan or a distributed computing application. This allows applications to use resources only. Decades before the first computers using this technology were invented, Robert A. Heinlein gave an example of how they might be used in his novel Stranger In A Strange Land: Opposite his chair was a stereovision tank disguised as an aquarium.
The first screensaver was written for the original IBM PC by John Socha, best known for creating the Norton Commander. The screensaver, named scrnsave, was published in the December 1983 issue of the Softalk magazine, it blanked the screen after three minutes of inactivity. By 1983 a Zenith Data Systems executive included "screen-saver" among the new Z-29 computer terminal's features, telling InfoWorld that it "blanks out the display after 15 minutes of nonactivity, preventing burned-in character displays"; the first screensaver that allowed users to change the activating time was released on Apple's Lisa, in 1983. The Atari 400 and 800's screens would go through random screensaver-like color changes if they were left inactive for about 8 minutes. Normal users had no control over this; these computers, released in 1979, are technically earlier "screen savers." Prior to these computers, games for the 1977 Atari VCS/2600 gaming console such as Combat and Breakout, included color cycling in order to prevent burn-in of game images into 1970s-era televisions.
In addition, the first model of the TI-30 calculator from 1976 featured a screensaver, which consisted of a decimal point running across the display after 30 seconds of inactivity. This was chiefly used to save battery power, as the TI-30 LED display was more power intensive than LCD models; these are examples of the firmware of a computer. Today with the help of modern graphics technologies there is a wide variety of screensavers; because of 3D computer graphics, which provide realistic environments, 3D screensavers are available. Screensavers are designed and coded using a variety of programming languages as well as graphics interfaces; the authors of screensavers use the C or C++ programming languages, along with Graphics Device Interface, such as OpenGL
The River Šuica is a sinking river flowing through Duvanjsko Polje and the wider region of Tropolje in Bosnia and Herzegovina. The river runs through its subterranean section, which begins at the point where river goes underground within the main estavelle at Kovači; this section of the Šuica is traversable for trained speleologists with proper equipment. Its sources are Mali Veliki Stržanj, both close to village of Stržanj, it flows through and drains most of its waters from Kupreško Polje, the Šuica Valley and Duvanjsko Polje. The river disappears underground in large Kovači estavelle, eponymous of nearby village Kovači, in southwestern corner of Duvanjsko Polje. Waters of the Šuica than re-emerges at the source of Ričina in village Prisoje, which than empties into the reservoir of Buško Blato after a short flow of cca 0–50 meters, depending on the water levels in reservoir
