Well, if I had to explain it to my wife it would have been something like that: The main idea is to avoid duplication of large data. Let’s take a look at a list of people and the country they came from. Instead of holding the name of the country which can be as long … Read more
Traditionally a program is compiled and a script is interpreted, but that is not really important anymore. You can generate a compiled version of most scripts if you really want to, and other ‘compiled’ languages like Java are in fact interpreted (at the byte code level.) A more modern definition might be that a program … Read more
It means that the two threads are not running in sync, that is, they are not both running on the same timeline. I think it’s a case of computer scientists being too clever about their use of words. Synchronisation, in this context, would suggest that both threads start and end at the same time. Asynchrony … Read more
ORM = Object-Relational Mapping In an ORM, classes/objects in the application are mapped to database tables and operations for persistence, sometimes automagically. DAL = Data-Access Layer In a DAL, database operations are hidden behind a code facade. An ORM is a kind of DAL, but not all DALs are ORMs.

In your case if you have User Interface for providing two numbers and then getting the result, it should be called a web application. But if you have an API exposed to receive two numbers and return result over http , then it should be called a web service. At low level, both Web application … Read more
The only reason to use the log-likelihood instead of the plain old likelihood is mathematical convenience, because it lets you turn multiplication into addition. The plain old likelihood is P(parameters | data), i.e. assuming your data is fixed and you vary the parameters of your model. Maximizing this is one way to do parameter estimation … Read more
My understanding is this: A computer program is a set of instructions that can be executed on a computer. An application is software that directly helps a user perform tasks. The two intersect, but are not synonymous. A program with a user-interface is an application, but many programs are not applications.
