The most important difference, and in fact the defining difference between a library and a framework is Inversion of Control. What does this mean? Well, it means that when you call a library, you are in control. But with a framework, the control is inverted: the framework calls you. (This is called the Hollywood Principle: … Read more
Type safety means that the compiler will validate types while compiling, and throw an error if you try to assign the wrong type to a variable. Some simple examples: // Fails, Trying to put an integer in a string String one = 1; // Also fails. int foo = “bar”; This also applies to method … Read more
It means to increment the version number to a new, unique value.
This is a shorter and hopefully clearer answer… Yes, the endpoint is the URL where your service can be accessed by a client application. The same web service can have multiple endpoints, for example in order to make it available using different protocols.
In the old days, “/opt” was used by UNIX vendors like AT&T, Sun, DEC and 3rd-party vendors to hold “Option” packages; i.e. packages that you might have paid extra money for. I don’t recall seeing “/opt” on Berkeley BSD UNIX. They used “/usr/local” for stuff that you installed yourself. But of course, the true “meaning” … Read more
Images are frozen immutable snapshots of live containers. Containers are running (or stopped) instances of some image. Start with the base image called ‘ubuntu’. Let’s run bash interactively within the ubuntu image and create a file. We’ll use the -i and -t flags to give us an interactive bash shell. $ docker run -i -t … Read more
Suppose, you want to count the number of times user clicked a button on a webpage. For this, you are triggering a function on onclick event of button to update the count of the variable <button onclick=”updateClickCount()”>click me</button> Now there could be many approaches like: You could use a global variable, and a function to … Read more
Relevant article on Programming.Guide: Dynamic programming vs memoization vs tabulation What is difference between memoization and dynamic programming? Memoization is a term describing an optimization technique where you cache previously computed results, and return the cached result when the same computation is needed again. Dynamic programming is a technique for solving problems of recursive nature, … Read more
Since you’re looking for correctness, login, logout, logon, and logoff are all nouns: “Please enter your login credentials.” “I see three logons but only two logoffs from this user.” The corresponding verbs are each two words: “Please log in to see your reputation.” “You must log off and talk to a human.” Update: according to … Read more
Static/Dynamic Typing is about when type information is acquired (Either at compile time or at runtime) Strong/Weak Typing is about how strictly types are distinguished (e.g. whether the language tries to do an implicit conversion from strings to numbers). See the wiki-page for more detailed information.
