A function returns a value and a procedure just executes commands. The name function comes from math. It is used to calculate a value based on input. A procedure is a set of commands which can be executed in order. In most programming languages, even functions can have a set of commands. Hence the difference … Read more
Come on guys 🙂 We could do it simpler, by examples: /this-is-an-endpoint /another/endpoint /some/other/endpoint /login /accounts /cart/items and when put under a domain, it would look like: https://example.com/this-is-an-endpoint https://example.com/another/endpoint https://example.com/some/other/endpoint https://example.com/login https://example.com/accounts https://example.com/cart/items Can be either http or https, we use https in the example. Also endpoint can be different for different HTTP methods, for … Read more
Anti-patterns are certain patterns in software development that are considered bad programming practices. As opposed to design patterns which are common approaches to common problems which have been formalized and are generally considered a good development practice, anti-patterns are the opposite and are undesirable. For example, in object-oriented programming, the idea is to separate the … Read more
A mask defines which bits you want to keep, and which bits you want to clear. Masking is the act of applying a mask to a value. This is accomplished by doing: Bitwise ANDing in order to extract a subset of the bits in the value Bitwise ORing in order to set a subset of … Read more
Is null an instance of anything? No, there is no type which null is an instanceof. 15.20.2 Type Comparison Operator instanceof RelationalExpression: RelationalExpression instanceof ReferenceType At run time, the result of the instanceof operator is true if the value of the RelationalExpression is not null and the reference could be cast to the ReferenceType without … Read more
This is totally personal and subjective, but I’d say that a website is defined by its content, while a web application is defined by its interaction with the user. That is, a website can plausibly consist of a static content repository that’s dealt out to all visitors, while a web application depends on interaction and … Read more
I think your search for a “standard” naming convention will be in vain. Here are my proposals, based on existing, well-known programs: A) C:\users\OddThinking\Documents\My Source\Widget\foo.src — Vim calls it file root (:help filename-modifiers) B) C:\users\OddThinking\Documents\My Source\Widget\foo.src ——- file name or base name C) C:\users\OddThinking\Documents\My Source\Widget\foo.src ___ (without dot) file/name extension D) C:\users\OddThinking\Documents\My Source\Widget\foo.src ____ (with … Read more
Rune literals are just 32-bit integer values (however they’re untyped constants, so their type can change). They represent unicode codepoints. For example, the rune literal ‘a’ is actually the number 97. Therefore your program is pretty much equivalent to: package main import “fmt” func SwapRune(r rune) rune { switch { case 97 <= r && … Read more
In simple words, a loop invariant is some predicate (condition) that holds for every iteration of the loop. For example, let’s look at a simple for loop that looks like this: int j = 9; for(int i=0; i<10; i++) j–; In this example it is true (for every iteration) that i + j == 9. … Read more
Adding # noqa to a line indicates that the linter (a program that automatically checks code quality) should not check this line. Any warnings that code may have generated will be ignored. That line may have something that “looks bad” to the linter, but the developer understands and intends it to be there for some … Read more
