“Bootstrapping” comes from the term “pulling yourself up by your own bootstraps.” That much you can get from Wikipedia. In computing, a bootstrap loader is the first piece of code that runs when a machine starts, and is responsible for loading the rest of the operating system. In modern computers it’s stored in ROM, but … Read more
The Constructor is a default method of the class that is executed when the class is instantiated and ensures proper initialisation of fields in the class and its subclasses. Angular, or better Dependency Injector (DI), analyses the constructor parameters and when it creates a new instance by calling new MyClass() it tries to find providers … Read more
client.user.presence returns a Presence, a very complex object. I believe you are looking for Presence#status, which will return online, offline, idle, or dnd Also, instead of adding every property to the userinfo object after it’s been defined, you could condense your code using object destructuring: Show code snippet Show code snippet
Looks like you are hitting the limit on connections per server. I see you are loading a lot of static files and my advice is to separate them on subdomains and serve them directly with Nginx for example. Create a subdomain called img.yoursite.com and load all your images from there. Create a subdomain called scripts.yourdomain.com … Read more
Casting in Java isn’t magic, it’s you telling the compiler that an Object of type A is actually of more specific type B, and thus gaining access to all the methods on B that you wouldn’t have had otherwise. You’re not performing any kind of magic or conversion when performing casting, you’re essentially telling the … Read more
You asked for a link that looks like a button, so use a link and a button 🙂 This will preserve default browser button styling. The button by itself does nothing, but clicking it activates its parent link. Demo:
Preliminaries JavaScript has only one data type which can contain multiple values: Object. An Array is a special form of object. (Plain) Objects have the form Arrays have the form Both arrays and objects expose a key -> value structure. Keys in an array must be numeric, whereas any string can be used as key … Read more
but as for this method, I don’t understand the purpose of Integer.MAX_VALUE and Integer.MIN_VALUE. By starting out with smallest set to Integer.MAX_VALUE and largest set to Integer.MIN_VALUE, they don’t have to worry later about the special case where smallest and largest don’t have a value yet. If the data I’m looking through has a 10 … Read more
for example, when to use it over foreach? You don’t use IEnumerable “over” foreach. Implementing IEnumerable makes using foreach possible. When you write code like: it’s functionally equivalent to writing: By “functionally equivalent,” I mean that’s actually what the compiler turns the code into. You can’t use foreach on baz in this example unless baz … Read more
XOR is short for exclusive or. It is a logical, binary operator that requires that one of the two operands be true but not both. So these statements are true: And these statements are false: There really isn’t such a thing as an”exclusive and” (or XAND) since in theory it would have the same exact … Read more
