Currently there are only about 5 different versions of Operating Systems, with several sub-versions. They are: Windows MacOS iOS Android Unix/Linux Now, technically Unix/Linux are different, and there are variations of these, but fundamentally at a high level they are the same. There are some others out there, but they are rare and often on…
Now that we’ve looked at a Intro to Search and have a basic idea of how a search engine works, now we need to look at what we can do to improve our own search results – i.e. those things that get returned when you type what you want into the search engine. Knowing that…
So we looked in an Intro to Search at why people need to search. But how do search engines work? For example, did you know that Google estimates that they only know about 40% of the web pages out there? But how did they learn about all those other pages? Well, lets look at what…
Do you know how many websites are on the Internet? To be honest, no one really knows, but the best guess is around 1.6 BILLION, and that was in 2018. Usually that number is going up. After all, it only takes a few bucks to create a website, if you aren’t using one of the…
Where client side programming is focused on mainly JavaScript at this point, server side programming has several popular programming languages including, but not limited to, PHP, ASP.Net, Ruby, Python, Java, and many more. The languages that are picked have to deal with what the developer is comfortable with, what the server is capable of handling,…
There used to be several client side languages, however, now almost all client side programming is done with JavaScript. JavaScript is a scripting language which directly interacts with the web browser. All of the interaction is done on the client’s side. It is most often used for simple things like form validation and moving items…
In the previous example, you saw how a constructor called a method for a class. But how? That object wasn’t created yet… right? Well sort of. When you build from a base/parent class, it’s no arg constructor is called first, creating a base class. That object is then able to call it’s functions. Let’s try…
You can extend almost any class you want. So once you’ve defined a base class, you just need to know enough about it, and how you want to derive from it. Considering our GenericGeometric class from before, let’s look at deriving a Circle class from it. In our header file we will have: Notice two…
