An Introduction to Algorithms

Published

on

In the modern world, algorithms do much of the digital heavy lifting.

Algorithms control the inner-workings of everything from particle accelerators to stock markets. They determine the news you see, what search results you get, how computers learn, and what gets recommended to you on Netflix or Amazon.

In short, society couldn’t function as-is without algorithms – and as we lean on them to run more things, it becomes more important for us to learn what they are and what they do.

Algorithms 101

Today’s infographic from Futurism digs into the origins of algorithms, and how they impact our everyday lives.

What are algorithms?

What is an Algorithm?

An algorithm is a predetermined set of steps for a computer to accomplish a task. It’s basically an instruction manual. And as in life, instruction manuals can be simple (e.g. building an Ikea side table) or extremely complex (e.g. filing a patent).

Below is “Sorting Out Sorting” (1981), a timeless primer on sorting methods. It clearly demonstrates the way computers approach sorting vast quantities of information by following a set of instructions.

A famous example of an algorithm is Google’s PageRank, which determines the order in which websites appear in Google’s search rankings. PageRank’s methodology is explained succinctly and effectively in the video below.

By building on a stochastic model called the Markov chain, PageRank revolutionized the way the world accesses information. The power of this algorithm is partially responsible for Google’s ability to control 41% of the online ad market, which is where Alphabet still generates the majority of its revenue.

How Algorithms Influence Society

Social platforms play a substantial role in delivering news and information to us. In fact, an estimated 44% of the U.S. population consumes news via Facebook. The more we rely on social networks to supply us with news, the more algorithms will influence what information we’re exposed to. Since social platforms are designed to serve us customized content, there is a growing concern that we are creating online echo chambers that crowd out opposing views.

Algorithms also have a profound influence on our economy. Roughly 50% of the market moves through high frequency trading – the process of using dedicated programs to make automated trading decisions to place orders. Large portions of our economy are now managed with very little human intervention.

In recent years, progress in the field of artificial intelligence has generated an abundance of interest and excitement. Deep learning (a technique for implementing machine learning) is making all kinds of machine-assisted tasks possible. Preventive healthcare, driverless vehicles, drug discovery, bioinformatics, and hyper-customized recommendations on shopping websites are all here today or coming down the pipeline.

Deep Learning

The remarkable thing about deep learning is that it goes beyond what any human can program a computer to do. Programmers have instead used a learning algorithm – fueled by terabytes of data – to train it to perform complex tasks. The computer essentially figures out for itself how to recognize the desired objects, text, or actions.

Breakthroughs like this are the reason AI startups are now receiving billions of dollars of funding.

The Algorithmic Economy

The potential upside for technology providers are enormous, particularly if proprietary processes work on a global scale. An era where “things” will communicate autonomously and take actions without human intervention is sure to profoundly impact our society.

The big question is, what will we do once computers and algorithms are taking care of business?

Mapped: The World’s Fastest (and Slowest) Internet Speeds

How quickly did this page load for you?

The answer depends on the device you’re using, and where in the world you’re located. Average internet speeds vary wildly from country to country.

Which countries have the fastest internet connection? Using data from the Speedtest Global Index™, this map ranks the fastest (and slowest) internet speeds worldwide, comparing both fixed broadband and mobile.

What Factors Affect Internet Speed?

Before diving in, it’s important to understand the key factors that impact a country’s internet speed. Generally speaking, internet speed depends on:

  1. Infrastructure or the type of cabling (copper or fiber-optic) that a country’s utilizing to support their internet service. Typically, the newer the infrastructure, the faster the connection.
  2. Proximity/connection to submarine cables is important, as these massive undersea fiber-optic cables transmit about 97% of the world’s communication data.
  3. The size of a country, since landmass affects how much it costs to upgrade infrastructure. The smaller the country, the cheaper it is to upgrade cabling.
  4. Investment makes a difference, or how much a country’s government prioritizes internet accessibility.

Of course, other factors may influence a country’s internet speed too, such as government regulation and intentional bandwidth throttling, which is the case in countries like Turkmenistan.

Ranked: Fixed Broadband Internet Speeds

The Speedtest Global Index uses data from hundreds of millions of people, in more than 190 countries, to measure both fixed broadband and mobile connections.

When it comes to the fastest fixed broadband, Singapore comes in first place, with a download speed of 262.2 mbps—more than double the global average.

Size could be a factor in Singapore’s speedy internet, as it’s one of the smallest
and also densest countries in the world. With a landmass of just 280 square miles, it’s around the same size as Austin, Texas.

The country’s government has also prioritized investment in digital infrastructure, especially in recent years. In 2020, the Singaporean government promised to invest $2.52 billion towards digital innovation, with a portion dedicated to upgrading the country’s telecom infrastructure.

At the opposite end of the spectrum, Cuba has the slowest fixed broadband, with a speed of 3.46 mbps. Along with poor government funding, Cuba also has limited access to submarine cables. While most countries are connected to several, Cuba is only connected to one.

Ranked: Mobile Internet Speeds

Mobile internet uses cell towers to wirelessly transmit internet to your phone. Because of this extra element, the ranking for mobile internet speeds varies from fixed broadband.

The United Arab Emirates (UAE) is first on the list, with a download speed of 195.5 mbps. Not only is mobile data fast in the UAE, it’s also relatively cheap, compared to other countries on the ranking. The average cost of 1 GB of data in the UAE is around $3.78, while in South Korea (#2 on the list) it’s $10.94.

The Future is 5G

Innovation and new technologies are changing the digital landscape, and things like 5G networks are becoming more mainstream across the globe.

Because of the rapidly changing nature of this industry, the data behind this ranking is updated monthly to provide the latest look at internet speeds across the globe.

This means the bar is gradually raising when it comes to internet speed, as faster, stronger internet connections become the norm. And countries that aren’t equipped to handle these souped-up networks will lag behind even further.

Ranked: Big Tech CEO Insider Trading During the First Half of 2021

Big Tech is worth trillions, but what are insiders doing with their stock? We breakdown Big Tech CEO insider trading during the first half of 2021.

Big Tech CEO Insider Trading During The First Half of 2021

When CEOs of major companies are selling their shares, investors can’t help but notice.

After all, these decisions have a direct effect on the personal wealth of these insiders, which can say plenty about their convictions with respect to the future direction of the companies they run.

Considering that Big Tech stocks are some of the most popular holdings in today’s portfolios, and are backed by a collective $5.3 trillion in institutional investment, how do the CEOs of these organizations rank by their insider selling?

CEOStockShares Sold H1 2021Value of Shares ($M)
Jeff BezosAmazon (AMZN)2.0 million$6,600
Mark ZuckerbergFacebook (FB)7.1 million$2,200
Satya NadellaMicrosoft (MSFT)278,694
$65
Sundar PichaiGoogle (GOOGL)27,000$62
Tim CookApple (AAPL)0$0

Breaking Down Insider Trading, by CEO

Let’s dive into the insider trading activity of each Big Tech CEO:

Jeff Bezos

During the first half of 2021, Jeff Bezos sold 2 million shares of Amazon worth $6.6 billion.

This activity was spread across 15 different transactions, representing an average of $440 million per transaction. Altogether, this ranks him first by CEO insider selling, by total dollar proceeds. Bezos’s time as CEO of Amazon came to an end shortly after the half way mark for the year.

Mark Zuckerberg

In second place is Mark Zuckerberg, who has been significantly busier selling than the rest.

In the first half of 2021, he unloaded 7.1 million shares of Facebook onto the open market, worth $2.2 billion. What makes these transactions interesting is the sheer quantity of them, as he sold on 136 out of 180 days. On average, that’s $12 million worth of stock sold every day.

Zuckerberg’s record year of selling in 2018 resulted in over $5 billion worth of stock sold, but over 90% of his net worth still remains in the company.

Satya Nadella

Next is Satya Nadella, who sold 278,694 shares of Microsoft, worth $234 million. Despite this, the Microsoft CEO still holds an estimated 1.6 million shares, which is the largest of any insider.

Microsoft’s stock has been on a tear for a number of years now, and belongs to an elite trillion dollar club, which consists of only six public companies.

Sundar Pichai

Fourth on the list is Sundar Pichai who has been at the helm at Google for six years now. Since the start of 2021, he’s sold 27,000 shares through nine separate transactions, worth $62.5 million. However, Pichai still has an estimated 6,407 Class A and 114,861 Class C shares.

Google is closing in on a $2 trillion valuation and is the best performing Big Tech stock, with shares rising 60% year-to-date. Their market share growth from U.S. ad revenues is a large contributing factor.

Tim Cook

Last, is Tim Cook, who just surpassed a decade as Apple CEO.

During this time, shares have rallied over 1,000% and annual sales have gone from $100 billion to $347 billion. That said, Cook has sold 0 shares of Apple during the first half of 2021. That doesn’t mean he hasn’t sold shares elsewhere, though. Cook also sits on the board of directors for Nike, and has sold $6.9 million worth of shares this year.

Measuring Insider Selling

All things equal, it’s desirable for management to have skin in the game, and be invested alongside shareholders. It can also be seen as aligning long-term interests.

A good measure of insider selling activity is in relation to the existing stake in the company. For example, selling $6.6 billion worth of shares may sound like a lot, but when there are 51.7 million Amazon shares remaining for Jeff Bezos, it actually represents a small portion and is probably not cause for panic.

If, however, executives are disclosing large transactions relative to their total stakes, it might be worth digging deeper.
