terminology - What does it mean when data is scalar? - Software . . . The word scalar derives from the Latin word scalaris, an adjectival form of scala (Latin for "ladder") The English word "scale" also comes from scala Source A Scalar is a variable that holds an individual value For example: Scalar Variable: Say that you are trying to represent the names of various students as a set of variables Each of the
What is meant by a primitive data type? For example, in languages like C and C++, you have a number of built-in scalar types - int, float, double, char, etc These are "primitive" in the sense that they cannot be decomposed into simpler components From these basic types you can define new types - pointer types, array types, struct types, union types, etc
performance - Why does expressing calculations as matrix . . . Using SIMD instructions (confusingly, this is also called "vectorization" but in a different sense than in the text quotes in the question) In essence, instead of 4 or 8 or so scalar arithmetic instructions, give the CPU one instruction that performs arithmetic on 4 or 8 or so registers in parallel This can literally make some calculations
data structures - How to represent a set in JSON? - Software . . . Take a scalar, say 0 or null and force it to be the value of every key in the map: {"a": 0, "b": 0} This way, under standard comparison tools, the objects are equal, even if the key ordering is changed However, this technique pollutes the JSON document with irrelevant data [4] - As an ordered list
Why Protobuf 3 made all fields on the messages optional? The syntax 3 of protobuf made all the fields optional dropping the keywords required and optional from previous proto2 syntax Reading some comments from developers it seems that it was done for
Algorithm for detection of overlapping between vectors where k is some scalar value in [0, 1] When you have transformed all your inputs into this form, it's fairly straightforward to find solutions where the lines overlap: When you have transformed all your inputs into this form, it's fairly straightforward to find solutions where the lines overlap:
Is it wrong to parse YAML `true` as a string? Alternatively, an editor can be type-agnostic but that can lead to seemingly trivial edits changing the type of a scalar Your coworker is slightly more correct assuming they are suggesting that you define a custom schema or parse without any YAML-level schema
