In many cases, the scope of an AP class is different than that of an Honors class -- for example, AP U.S. History covers 500 years of history as opposed to Honors covering 100 years. A conversation with the teacher can be helpful. I would recommend that the student's interests be a guiding principle in course selection. If a student loves art, he or she might want to try AP Art to explore the interest in a deeper way. Not only will it make school a happier place, which generally makes for a more successful student, but it also shows colleges another dimension to the applicant.

Colleges generally want students to complete at least two years of a world language; most will prefer to see that a student has studied the same language for at least three years. If a student chooses to drop a language, the replacement course is important. For example, does the student want to double up on science classes because that is a passion?

For younger students who are struggling with their world language class, it is generally preferable to switch to try another language after two years rather than dropping a language from the schedule entirely.

The history of the graphical user interface, understood as the use of graphic icons and a pointing device to control a computer, covers a five-decade span of incremental refinements, built on some constant core principles. Several vendors have created their own windowing systems based on independent code, but with basic elements in common that define the WIMP "window, icon, menu and pointing device" paradigm.

There is still some controversy over the amount of influence that Xerox's PARC work, as opposed to previous academic research, had on the GUIs of the Apple Lisa and Macintosh, but it is clear that the influence was extensive, because first versions of Lisa GUIs even lacked icons.[8][9] These prototype GUIs are at least mouse-driven, but completely ignored the WIMP ( "window, icon, menu, pointing device") concept. Screenshots of first GUIs of Apple Lisa prototypes show the early designs. Apple engineers visited the PARC facilities (Apple secured the rights for the visit by compensating Xerox with a pre-IPO purchase of Apple stock) and a number of PARC employees subsequently moved to Apple to work on the Lisa and Macintosh GUI. However, the Apple work extended PARC's considerably, adding manipulatable icons, and drag and drop manipulation of objects in the file system (see Macintosh Finder) for example. A list of the improvements made by Apple, beyond the PARC interface, can be read at Folklore.org.[10] Jef Raskin warns that many of the reported facts in the history of the PARC and Macintosh development are inaccurate, distorted or even fabricated, due to the lack of usage by historians of direct primary sources.[11]

The standard windowing system in the Unix world is the X Window System (commonly X11 or X), first released in the mid-1980s. The W Window System (1983) was the precursor to X; X was developed at MIT as Project Athena. Its original purpose was to allow users of the newly emerging graphic terminals to access remote graphics workstations without regard to the workstation's operating system or the hardware. Due largely to the availability of the source code used to write X, it has become the standard layer for management of graphical and input/output devices and for the building of both local and remote graphical interfaces on virtually all Unix, Linux and other Unix-like operating systems, with the notable exceptions of macOS and Android.

In the first decade of the 21st century, the rapid development of GPUs led to a trend for the inclusion of 3D effects in window management. It is based in experimental research[citation needed] in user interface design trying to expand the expressive power of the existing toolkits in order to enhance the physical cues that allow for direct manipulation. New effects common to several projects are scale resizing and zooming, several windows transformations and animations (wobbly windows, smooth minimization to system tray...), composition of images (used for window drop shadows and transparency) and enhancing the global organization of open windows (zooming to virtual desktops, desktop cube, Expos, etc.) The proof-of-concept BumpTop desktop combines a physical representation of documents with tools for document classification possible only in the simulated environment, like instant reordering and automated grouping of related documents.

Now, we need to calculate what focal length gets this horizontal angle of view. If we use this lens, the screen will become our natural window to the world. The lens projection will match the angle of viewing of our eyes in the screen area. e24fc04721
