The Three Development Paradigms: Procedural, Object-Oriented, and Functional | WPShout

three pears

When you’re brand new to development in PHP or JavaScript, you don’t really need or want to think too hard about programming paradigms. You just want to get things to work. And that makes a lot of sense. But eventually as you go along, you start to wonder. What’s this “OOP” thing people seem obsessed with? Am I doing that? Should I be?

Fundamentally, this article is for people in a place like that. Our goal today is to clarify what these three major paradigms in software development are, how they relate to each other, and which you’ll want to use when. Contrary to popular belief, there isn’t a “right” or “wrong” answer ever.

Before we start breaking down all the programming paradigms we’ll cover, it makes sense to be clearer about what we mean by “paradigms”. To cite a definition which is relevant, the American Heritage Dictionary says a paradigm is:

A set of assumptions, concepts, values, and practices that constitutes a way of viewing reality for the community that shares them, especially in an intellectual discipline

Difference Between SPF and UPF Rating System – Sungrubbies.com

UPF what you need to know

 

SPF vs. UPFSummary of all major differences between SPF and UPF rating systems. What you need to know about SPF and UPF.

Both SPF (Sun Protection Factor) and UPF (Ultraviolet Protection Factor) are standards used to measure sunburn protection. SPF, the standard used to measure the effectiveness of sunscreens, has been around for many years. The UPF system is relatively new and was created specially for sun protective fabrics. At first, American sun protective fabrics were rated using the SPF standard until the FTC finalized the UPF standard we have today. Use of the UPF standard is voluntary so some sun protective fabric manufactures still use the SPF system.

Tetrahedron

Tetrahedron

Four triangular faces along with six edges meeting at four vertices together describe the regular tetrahedron. The tetrahedron is the root of all entanglements that shape the perceivable bonds that hold life together in this dimension. The regular tetrahedron can be found at the source of all three-dimensional forms and is fundamental in the creation of all patterns and holographic configurations.

“All of the definable structuring of Universe is tetrahedrally coordinate in rational number increments of the tetrahedron. By tetrahedron, we mean the minimum thinkable set that would subdivide the Universe and have the interconnectedness where it comes back upon itself. The basic structural unit of physical Universe quantation, tetrahedron has the fundamental prime number oneness.”

Buckminster Fuller

“Within it (tetrahedron) lies the energy that holds all life together. The bonds that hold atoms, particles and molecules together, all the way down to nanoparticles and all the way up to macroparticles, are tetrahedral. Everything that exists as you conceive of it in a 3-dimensional world, is held together by these tetrahedral bonds.”

Buckminster Fuller

“The tetrahedron is a form of energy package. The tetrahedron is transformable…All of the definable structuring of Universe is tetrahedrally coordinate in rational number increments of the tetrahedron.”

Buckminster Fuller

“Two Triangular Energy Events Make Tetrahedron: The open-ended triangular spiral can be considered one “energy event” consisting of an action, reaction and resultant. Two such events (one positive and one negative) combine to form the tetrahedron.”

The shape of the universe

shape of the universe
What shape is the Universe
What shape is the Universe?

There are three possible geometries of the universe: closed, open and flat from top to bottom. The closed universe is of finite size and, due to its curvature, traveling far enough in one direction will lead back to one’s starting point. The open and flat universes are infinite and traveling in a constant direction will never lead to the same point.

Universe with positive curvature. A positively curved universe is described by elliptic geometry, and can be thought of as a three-dimensional hypersphere, or some other spherical 3-manifold (such as the Poincaré dodecahedral space), all of which are quotients of the 3-sphere.

Cryptocurrencies, Explained: How Blockchain Technology Could Solve 3 Big Problems Plaguing the Art Industry

  • PROBLEM 1: THE LINGERING MYSTERIES OF PROVENANCE & AUTHENTICITY

PROBLEM 1: THE LINGERING MYSTERIES OF PROVENANCE & AUTHENTICITY

Relatively few artworks today offer the air-tight security of a certificate of authenticity backed by an unbroken chain of title. Gaps in the provenance paper trail undermine both sides of the market, with collectors often left to wonder if they’re being presented looted works or outright fakes, and sellers sometimes forced to accept lower offers due to buyers’ hesitance over the uncertainties.

Super Blood Moon 2018

The rare Super Blue Blood Moon is about to happen for the first time in 150 years!

Early Wednesday morning brought a lunar event that hasn’t been seen since 1866.

It was at least partially visible in all 50 U.S. states, though the views were better the farther west you live.

Let’s break this down. This event – called a super blue blood moon – was actually three fairly common lunar happenings all happening at the same time.

And scientists say that information gathered during the event could help them figure out where to land a rover on the moon.

How is what3words able to provide accurate address of every location?

With what3words, Chris Sheldrick and his team have divided the entire planet into three-meter squares and assigned each a unique, three-word identifier, like famous.splice.writers or blocks.evenly.breed, giving a precise address to the billions of people worldwide who don’t have one. In this quick talk about a big idea, Sheldrick explains the economic and political implications of giving everyone an accurate address — from building infrastructure to sending aid to disaster zones to delivering hot pizza.

We have named every 3mx3m in the world with unique combination of 3 words.

Geospatial Start up of the Year is valuable recognition for What3Words.

The Idea behind what3words was to use words 3 words as it is easy for people to grasp.

We use latitude and longitude with our algorithm to generate 3 words addressing.

We do not use any address or pass code or anything which is much bigger then 3 meters.

Pythagorean theorem

Pythagorean Theorem

What do Euclid, 12-year-old Albert Einstein, and American President James A. Garfield have in common?

They all came up with elegant proofs for the famous Pythagorean theorem:

In mathematics, the Pythagorean theorem, also known as Pythagoras’s theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

3 THINGS THAT HAPPEN WHEN YOU STOP SHOWERING FOR A MONTH

Bathing
  • You won’t actually smell
  • Your skin will moisturize itself
  • You’ll save so much extra time

Ever skip a shower after a workout? Maybe. What about skip a shower for an entire month? That’s what one writer from The Atlantic, James Hamblin, set out to do.

No, it wasn’t out of laziness (although we wouldn’t quite blame him). It was actually an experiment to see whether his natural microbes—found in the gut, as we know, but also on the skin—were enough to keep him smelling clean and fresh, without any extra products. (He did wash his hands regularly, though, and rinsed off when he was visibly dirty, “like after a run when I have to wash gnats off my face, because there is still the matter of society.” Good call.)

Eclipses

types of solar eclipses

Eclipses, solar and lunar, have fascinated scientists and lay people for centuries. In ancient times, eclipses were seen as phenomena to be feared – many cultures came up with stories and myths to explain the temporary darkening of the Sun or the Moon. In recent centuries, eclipses have been sought after by scientists and astronomers who use the events to study and examine our natural world.

Solar eclipses can only occur during a New Moon when the Moon moves between Earth and the Sun and the 3 celestial bodies form a straight line: Earth–Moon–Sun.

There are between 2 and 5 solar eclipses every year.

There are 3 kinds of solar eclipses: total, partial, and annular. There is also a rare hybrid that is a combination of an annular and a total eclipse.

color blindness

Normal Vision
Normal Vision

There are three main kinds of color blindness, based on photopigment defects in the three different kinds of cones that respond to blue, green, and red light. Red-green color blindness is the most common, followed by blue-yellow color blindness. A complete absence of color vision —total color blindness – is rare.

Deuteranomaly
Deuteranomaly

People with ‘faulty’ trichromatic vision will be colour blind to some extent and are known as anomalous trichromats. In people with this condition all of their three cone types are used to perceive light colours but one type of cone perceives light slightly out of alignment, so that there are three different types of effect produced depending upon which cone type is ‘faulty’.

The different anomalous conditions are protanomaly, which is a reduced sensitivity to red light, deuteranomaly which is a reduced sensitivity to green light and is the most common form of colour blindness and tritanomaly which is a reduced sensitivity to blue light and is extremely rare.
