GPS signals can also be affected by multipath issues, where the radio signals reflect off surrounding terrain; buildings, canyon walls, hard ground, etc. These delayed signals cause measurement errors that are different for each type of GPS signal due to its dependency on the wavelength.
List of FTP server return codes. FTP server return codes always have three digits, and each digit has a special meaning. [1] The first digit denotes whether the response is good, bad or incomplete: Range. Purpose. 1xx. Positive Preliminary reply. The requested action is being initiated; expect another reply before proceeding with a new command.
Command-line interface. A command-line interface (CLI) is a means of interacting with a computer program by inputting lines of text called command-lines. Command-line interfaces emerged in the mid-1960s, on computer terminals, as an interactive and more user-friendly alternative to the non-interactive interface available with punched cards ...
The error() function can be used to show the value of a variable at any point in the module. So to know the value of a variable var at a certain point in the code, add the line error(var) at that point. In the case that the variable is a table (let's call the variable tab), mw.dumpObject(tab) can be used to show the table.
Euclidean distance. In mathematics, the Euclidean distance between two points in Euclidean space is the length of the line segment between them. It can be calculated from the Cartesian coordinates of the points using the Pythagorean theorem, and therefore is occasionally called the Pythagorean distance. These names come from the ancient Greek ...
The coordinates are valid in the region < <, < <, which is often called the Rindler wedge, if represents the proper acceleration (along the hyperbola = /) of the Rindler observer whose proper time is defined to be equal to Rindler coordinate time. To maintain this world line, the observer must accelerate with a constant proper acceleration ...
Different command-line argument parsing methods are used by different programming languages to parse command-line arguments. Programming languages. C C uses ...
The test command in Unix evaluates the expression parameter. In most recent shell implementations, it is a shell builtin, even though the external version still exists.In the second form of the command, the [ ] (brackets) must be surrounded by blank spaces (this is because [is a program and POSIX compatible shells require a space between the program name and its arguments).
