Having the characters and the numbers and making the associations is also called a mapping (verb). It differs from a function, as a function takes some input and produces the output based on some calculation. Mappings generally do not do a calculation, but instead some sort of look-up. Share.
From Section 5.3 of Google's paper describing MapReduce. "A Map function extracts a 10-byte sorting key from a text line and emits the key and the original text line as the intermediate key/value pair. We used a built-in Identity function as the Reduce operator. This function passes the intermediate key/value pair unchanged as the output key ...
No, you can never exceed 4GiB of simultaneously addressable memory for a 32-bit binary. Usually, the kernel takes half and you are left with 2GiB user. Some kernels support a compromise split of 1GiB/3GiB. However, you can ask the OS to map different portions of a file into memory at different times, essentially performing time multiplexing of ...
I'm going through a program written in C/C++ for control in robotics. Basically, three different programs run at the same time, and they communicate via shared memory. Google-ling around I found thinks like vxWorks and the boost libraries interprocess headers (Boost documentation: Sharing memory between processes).
In the program, we don't have to care if we expose a REST service or a SOAP service or whatever. Simply throw an exception, it will be handled correctly later. The caller gets enough and correct information if something goes wrong (as long as the exceptions have meaningful names and information). Logging can also be centralised.
Here is your library :) And you dont need to pass full K-table, only fields that you are interested in :) It assumes that its AND operator in truth table.
Program to an interface, not an implementation; Role interfaces; Make decisions in one place; Program to an interface. Say this variable is used in at least one long hard to read method. If it is declared as a map and not something concrete I can instantly tell that I could refactor to any map implementation without even having to read the long ...
Imperative programming - In good old days, when programming was broadly in assembly, code would have tons of GOTOs. Even higher level languages like FORTRAN and BASIC began using the same primitives. In this programming paradigm, the entire program is a single algorithm or complete functionality written linearly - step-by-step.
The easiest way to display these in a 2D plane is streamslice. Calculating and plotting these fields in MATLAB is just a case of setting up the physical equations in a vectorised form and calculating them for a grid of coordinates through which MATLAB can draw contours and field lines. Using the equation for electrical potential in the form ...
Assembly opcodes have, for the most part, a one-to-one correspondence with the underlying machine instructions. So all you have to do is identify each opcode in the assembly language, map it to the corresponding machine instruction, and write the machine instruction out to a file, along with its corresponding parameters (if any).
