What Is MVC? Simple Explanation

What Is MVC? Simple Explanation

Have you ever wondered what MVC means in programming or how it really works? MVC stands for Model, View, Controller, and it is an architectural paradigm used by many web frameworks such as Ruby on Rails, Laravel, CakePHP, Django and more. It is a way of thinking organizationally when coding.

In MVC everything has its own place so you can catch up on projects easier and find snippets of code when debugging or improving a page. It also makes the application efficient and secure since only certain elements can do certain things. For example, only Models talk to the database, and only Views contain HTML markup and so forth.

Creating Opportunity Through the Sharing Economy | Emily Castor | TEDxSacramentoSalon

Creating Opportunity Through the Sharing Economy | Emily Castor | TEDxSacramentoSalon

Emily makes the case that ride and car sharing are not only a promising transportation alternatives, especially as the urban population continues to grow worldwide, but such examples of collaborative consumption are transformative agents for our economy and culture that increase personal freedom and move us closer toward the sharing economy.

Emily Castor believes authentic communication can build meaningful communities around transportation. Emily is an original Lyft team member who has helped develop the ride sharing service into what it is today as the Director of Community Relations. Along the way, she honed her expertise in the shared economy through work with Congress, political candidates, and Universities. She learned the importance of having a presence on social media, and has turned her social presence into grassroots mobilization and community outreach. From here, she is working to pass laws on Capitol Hill, and encourage policy makers to adopt ridesharing as an environmentally-conscious and community-based alternative form of transportation. In her free time, Emily hosts Collaborative Chats, a monthly panel discussion for citizens, entrepreneurs, academics, and thought leaders to build community and discuss emerging issues of relevance to the sharing economy.

The Advantages and Disadvantages of the Sharing Economy

The Advantages and Disadvantages of the Sharing Economy

In the modern world, we have a new kind of sharing economy – one that provides all services that you can possibly need at 24/7 with just the click of a button. This economy is also known as on-demand or “gig economy.” This phenomenon isn’t new, but it’s indeed bigger and more user-friendly than ever now. The advantages include flexibility, a huge variety of jobs, not having to work all of the time. That is a great way to side hustle and have extra money to your income. But disadvantages are no health insurance, no stability and lack of protections.

Functional Programming In An Imperative World

Functional Programming In An Imperative World

Let’s start by looking at the core concepts that differentiate FP from the OO / imperative style most programmers are familiar with. Along the way it will be introduced you:

1. Immutable data structures. Having data structures that don’t change makes your code safer. Especially when dealing with concurrency and parallelism. However, they require you to approach solutions in a different way than you would with mutable data.

2. «Pure» functions. Pure, or idempotent, functions do not mutate state or cause other kinds of side effects. As a result, you are guaranteed that every time you call a function with the same parameters, you will always get the same value.

3. Recursion: While recursion is something most of us know about, it’s not something we tend to use often in imperative programming, and with good reason. Nonetheless, it’s a worth knowing about it’s various forms.

4. Function composition. When you have pure functions that handle only one task, you can build larger, more complex and more beneficial programs by composing functions together to form new functions.

5. First class functions: passing around functions as parameters and return values, just like any other object.

6. The holy trinity: map, reduce, filter. After all, these three functions are the work horses of FP, helping us manipulate and transform data quickly and elegantly.
