Rivalry 1, E-commerce — The incumbent: Amazon

While many e-commerce companies have come and gone, Amazon has remained a stalwart since 1994. The "Everything Store" has made its name for selling just that, everything from books to food to clothes. While many brick-and-mortar stores have an online equivalent, Amazon's online-first presence cemented its dominance in online shopping. That is, until one startup decided to take them on by hitting them where it hurts: pricing.

The challenger: Jet

Meet Jet, an online competitor determined to beat Amazon. The young company launched to much fanfare in 2015 with lower prices than the incumbent. Its bet was to have its members pay a fee, but it soon scrapped that and changed its business model so its products would be cheaper (but not by much less) than Amazon. Its CEO Marc Lore said at the time that the extra 4% to 5% off Amazon's prices was enough to entice buyers when making their orders.

Damage report: Amazon still has the edge, at least for now.

While Jet has struggled to find a sustainable business plan, Amazon's finances remain strong and don't seem to be impacted by the upstart yet. Don't count Jet out though — the company is well-funded having raised more than $565 million and people love saving money. While an Amazon membership does come loaded with perks like TV and free two-day shipping, Jet's lower cost selection might find its own niche in customers who are looking for a deal, not perks.

Do your bananas always go brown too fast? Do your greens wilt and wither away in the fridge?

If you're like me, you may feel like you're constantly wasting food because it goes bad before you have a chance to consume it.

But waste no more — we've compiled some handy tips on how to keep your food fresher for longer.

Wrap banana stems in plastic wrap because the stems produce ethylene gas that makes the fruit ripen faster. To keep them fresh even longer, separate the bananas and wrap each stem individually.

It's 21 feet of coach-built, English luxury.

Bentley unveiled the new Mulsanne Grand Limousine by Mulliner at the Geneva Motor Show this morning. It's the latest creation of Mulliner, their in-house coach-building division.

Over three feet longer than the standard Mulsanne, the Grand Limousine features "private-aviation style" club seating in the rear cabin, iPad docking stations, fold-out tables, champagne flutes and a bottle cooler, and a "soft-drink cabinet" with custom tumblers.

Bentley also notes that its coach-builders at Mulliner can customize the Mulsanne Grand Limousine to any customer's specifications.

With competitive pay, highly-rated benefits, and a reputation as a "fun place to work and a place where you can grow quickly," lots of people are clamoring to work at Whole Foods Market.

The healthy grocery store chain has more than 88,000 "team members" and has earned a spot on Fortune magazine's annual "100 Best Companies to Work For" list every year since its inception in 1998.

Based on Glassdoor reviews of the interview process there, earning a coveted spot at Whole Foods is by no means a breeze.

Here are some of the toughest questions people who have interviewed with the company say they've been asked:

The fast-food hot dog wars are on. 

On February 23, Burger King added grilled hot dogs to the menu. 

Checkers & Rally's responded the next day by selling its hot dogs for 79 cents. 

"It's a war we plan to win!" the company said in a news release.

But who serves the best wiener?

I taste-tested hot dogs from Five Guys, Burger King, Shake Shack, and Checkers. The winner surprised me.

First up, Checkers. As I waited in line, I scoured the menu for a hot dog but all I saw was a chili dog. When I asked the employee for one regular hot dog, she looked at me as if I had four heads. Guess that's not a typical order...

"OK, that will be 86 cents," the worker said. Then I looked at her as if she had four heads.

But I can see why it's so cheap. It's small, messy and depressing. The bag's face mirrored my own.

Talking from experience, doing yoga by yourself as a beginner is very difficult.

Even if you have an app or some sort of program that walks you through a routine, it's difficult to watch something while contorting your body.

A new clothing line called Nadi thinks it has a solution to perfecting poses solo: yoga pants that vibrate to guide you to the correct post. Here's how they work:

The yoga pants use haptic vibrations to guide you to the correct post.

RAW Embed

There are three motors placed around the hips, two behind the knees, and one on the ankle. The pants will vibrate in the different locations to indicate how to correct your desired pose.

So if your pigeon pose, pictured above, would benefit from moving your hips more center, then the pants will vibrate only in that area to relay that message. 

The pants also come with a corresponding app that will visually guide you to the correct pose, but viewing it is optional.

You can throw your phone to the side and the pants will still function.

We all have those friends who seemingly cruise through life, never stressing about money or success, and somehow always have plenty of both.

They have retirement plans, businesses and time to climb mountains or run marathons. Basically, they’re really annoying.

For others, failing to save, going deeper into debt and generally stressing about life is the norm. if you’re wondering what those successful friends of yours are thinking — but not saying — about your money habits, keep reading.

1. You need to budget.

You know the guy who you’re always hitting up for money until you get your paycheck? Well, he’s thinking that you would benefit by creating and sticking to a budget. Fortunately, making a budget is as easy as clicking a mouse.

"Find an app or system that works well for you such as Mint, You Need A Budget or just an Excel spreadsheet," said Kate Holmes, a certified financial planner (CFP) and founder of Belmore Financial. "Import the last few months of all checking, debit and credit card transactions and see where things are at. You’ll likely be surprised by some of the category totals."

"Ask yourself how much happiness each item brings. You may find some unnecessary spending you can easily cut out," she said.

Read:5 Signs You Have a Spending Problem

Here’s a strategy she recommended: 50% of your take-home pay goes for food, housing and other necessities; 30% for discretionary spending; and 20% toward paying off debt and building savings. Of course, any money-savvy friend will also tell you that making a budget is easy. Staying with it can be challenging.

2. You don't save enough.

We all want to retire someday, right? Well, the bad news is most of us won’t be retiring in style if we only rely on Social Security benefits to live. The average Social Security recipient in 2014 got only $1,300 a month. Those golden years are starting to look tarnished already.

So what can you do? Save in your workplace retirement plan and take advantage of your employer’s matching program, said consumer finance expert Kevin Gallegos, vice president of Phoenix operations for Freedom Financial Network. He recommended saving 10 percent to 15 percent of your gross pay for retirement. If you can’t swing that, start with what’s manageable for you.

3. You have too much credit card debt.

The financially savvy see credit cards as a convenience, not a bank account from which to draw. The average credit card interest rate stands at 13%, meaning that everything you buy, from dinner out to a flat screen TV, will cost you 13% more if you don't pay it off immediately.

That's why a good friend would tell you to avoid using credit cards except in emergencies. "Few, if any, investments will return as much," said Gallegos. "Having no credit card debt provides a financial cushion itself."

So the next time you whip out that Visa to fund your latest impulse buy, add in the interest costs and reassess whether it's really worth it.

After the first box-office bomb of the year, Gerard Butler will return to theaters this weekend in the sequel to 2013's "Olympus has Fallen," cleverly called "London has Fallen."

You may remember "Olympus has Fallen" — a movie about a president taken hostage — for bearing a striking resemblance to Channing Tatum's movie "White House Down," which came out three months later.

Critics and fans alike were quick to point out how similar the two movies were to each other.

But this wasn't the first time two films with "twin" plots were released around the same time, and it certainly won't be the last.

So why does this happen so frequently? It's all about the competition.

Forbes contributor Mark Hughes summed it up best in a 2011 Quora post explaining that sometimes it's just coincidence. However, it could also be to piggyback off a competitor's potentially successful — or already successful — project. 

Read the rest of his explanation here, and keep scrolling to see 25 "twin" films that have come out months apart in theaters over the years.

1993/1994: "Tombstone" and "Wyatt Earp" are both centered around Western lawman Wyatt Earp.

Box Office
"Wyatt Earp": $25 million
"Tombstone": $56.5 million

Neither film did overwhelmingly great at the box office. "Tombstone," starring Kurt Russell and Val Kilmer, edged out the Kevin Costner and Dennis Quaid film from Warner Bros.

1997: "Dante's Peak" and "Volcano" both revolve around the cast outrunning erupting volcanoes.

Box Office
Dante's Peak": $178 million 
"Volcano": $122.8 million

Fox got a little excited with its over-the-top posters for "Volcano." The film did nowhere near as well as Pierce Brosnan's volcano epic in the states; however, the Los Angeles centered movie picked up overseas.

1998: The Earth was nearly destroyed in both "Armageddon" and "Deep Impact."

Armageddon": $553.7 million
"Deep Impact": $349.5 million

Billionaire investors Warren Buffett, George Soros, and Carl Icahn are among the most tracked and emulated investors on the planet, and for good reason. All three have carved out billions of dollars in gains over investing careers stretching back 50 or more years.

Although investors should always do their own homework, each of these billionaires recently filed 13F reports with the Securities and Exchange Commission that show what stocks they've been buying. Since those 13Fs can be a treasure trove for new investment ideas, let's take a closer look at three stocks Buffett, Soros, and Icahn are betting will go higher.

Warren Buffett bets on an energy bargain

Buffett's legendary buy-and-hold investing style has turned Berkshire Hathaway into a global conglomerate with more than $100 billion in equity investments, and in the fourth quarter, one of Berkshire Hathaway's most interesting buys was Kinder Morgan.

Kinder Morgan is one of the largest energy-infrastructure companies in North America, and its pipelines kick off plenty of investor-friendly cash flow that in the past was returned to investors via dividends. However, facing headwinds tied to the global crude oil glut, Kinder Morgan announced plans in December to cut its dividend by 75% to limit debt and protect its investment-grade credit rating.

Historically, Buffett has favored companies that use their cash flow to improve their business, rather than pay dividends, and Kinder Morgan's debt plan could be why he's become a fan, but his $400 million stake could also be tied to a broader belief that a steep sell-off in the sector has made energy stocks a bargain. In 2015, Kinder Morgan's shares fell 63%. 

Although Buffett may think that Kinder Morgan's shares are cheap, he's recently been a bit more active with energy stocks in his portfolio, and that suggests that investors interested in owning Kinder Morgan may want to keep a close tab on Berkshire Hathaway's future filings to see if his opinion changes.

George Soros' bets on interest rates

George Soros is the legendary investor behind Soros Fund Management, which made a big 7.1 million-share bet on Synchrony Financial last quarter.

Synchrony Financial is the legacy credit card business spun out of General Electric Capital as part of a restructuring in July 2014. The company is the largest store-brand credit card issuer in the United States, and its credit card partners include the retail giants Wal-Mart and T.J. Maxx.

Soros Fund Management's acquisition hints that the fund's managers believe that credit card rates -- and the profits associated with the spread between Synchrony Financial's borrowing and lending rates -- are heading higher. Last year, Synchrony Financial reported net interest income of $12 billion, up 7%, and net profit of $2.1 billion, up 5%, so an improvement in spreads could move the needle nicely.

Admittedly, Soros' fund usually takes a rapid-fire approach to investing that has them moving in and out of positions quickly, but the size of its Synchrony Financial position may indicate a willingness to stick around longer than normal. You might want to, too. 

Carl Icahn's latest activism

Activist investor Carl Icahn's most intriguing buy last quarter was a nearly $1 billion stake in Xerox Corporation, the long-standing business service company best known for its copiers, and given that Xerox announced a restructuring in January, Icahn may already be putting his stamp on the company.

Xerox plans to split into two publicly traded companies: one that focuses on document technology, and another that does business process outsourcing (BPO). The document technology business and BPO business will have roughly $11 billion and $7 billion in trailing sales, respectively.

In addition to the split, Xerox is also taking an eraser to its expenses. Management expects cost-saving moves to cut expenses by $700 million this year and that the split will allow the company to shave $2.4 billion in expenses over the coming three years. Those savings should offer a nice tailwind to profit. Since Xerox expects the deal to close by the end of this year, investors interested in following in Icahn's footsteps might want to get involved sooner, rather than later.

Alexandra Andresen is the youngest billionaire in the world.

Forbes revealed in its 2016 ranking of the richest people on earth that the Norwegian heiress, 19, is now worth $1.2 billion (£862 million). In 2007, her father, Johan Andresen, transferred to her 42% of the stock in Ferd, the family's centuries-old private-investment company.

He also transferred a 42% stake in the company to her sister, Katharina, who at 20 is the second-youngest billionaire in the world. She's also worth $1.2 billion.

Alexandra was only recently confirmed as the world's youngest billionaire because the Norwegian government publishes the tax returns of people over 17.

But despite her affluent upbringing in one of the most famous families in Norway, she isn't just any rich kid. Alexandra is already an accomplished horse rider, winning several massive competitions in dressage.

Her parents also taught her to be humble and save. So even though she is worth over a billion dollars, she actually saved her pocket money during her younger years and only drove second-hand cars.

Take a look at the incredible life Alexandra Andresen has led so far:

Alexandra Andresen was born in 1997 in Oslo, Norway, where she was also primarily raised.

Her father is Johan Andresen, son of industrialist Johan Henrik Andresen and Marianne Ebba Therese Bielke.

The Andresen family made their money from their tobacco brand, Tiedemanns, which the clan held until 2005 under Ferd. Today, Ferd mainly runs hedge funds. It is an active investor on the Nordic stock exchange and has private equity investments, too.

In the future the global employment market will rely heavily on robots, artificial intelligence, and all sorts of automation.

In fact, technology is so crucial going forward, that in January, the World Economic Forum predicted that in less than five years more than five million human jobs will be replaced by automation, AI, and robots. 

Just this week, a new report showed nearly a third of retails jobs in the UK could disappear by 2025, with many workers replaced by technology in some way or another.

But which jobs in London are at the most risk of being done by robots in the future? As part of its "Global cities, global talent" report, Big Four accountancy firm Deloitte took a look into the jobs in Britain's capital at the highest risk of automation moving forward.

Deloitte ranked job sectors using data from Oxford University academics Carl Frey and Michael Osborne, and the ONS, before creating a ranking from what it calls the "proportion of jobs at high risk of automation." Most of the jobs at risk of being taken by robots generally involved low skilled, manual work, but some of them might surprise you.

Check out the list below.

13. Information and communication — 3%: Information and communication workers don't need to lose much sleep over their incomes. A massive 97% of jobs in the sector are considered to be at "low risk of automation."

12. Education — 8%: Teachers don't need to worry too much about having their jobs stolen by robots in the coming years, with just 8% of jobs in the education sector at high risk of automation.

11. Arts, entertainment and recreation — 23%: Actors, musicians, and anyone else working in the entertainment industry have a 23% chance of having their job automated. However, nearly two thirds of jobs in the sector are safe for the time being.

To be among the top 10% in San Francisco, your salary needs to reach at least $238,855. And to crack the top 25%, you need to earn $141,790.

That's according to an interactive tool from The New York Times that allows you to enter your household income and compare your earnings across 344 zones throughout the US. 

Here, we've highlighted the annual household income required to be in the top 10% and top 25% in 25 major US cities, from lowest to highest income needed.

William Henry Gates III was born in Seattle, Washington on October 28th, 1955, the son of a lawyer and a banking executive. Because of his suffix, his childhood nickname was "Trey."

Gates' parents were grooming him to be a lawyer. His parents enrolled him at the Lakeside School, a rigorous Seattle private high school that future Microsoft cofounder Paul Allen also attended.

But Lakeside is also where the course of Gates' life changed. In eighth grade, the Lakeside Mothers Club used cash from a rummage sale to give students access to a Teletype Model 30 computer hooked up to the General Electric mainframe. Gates fell in love with the idea of computers.

As Annie Dillard writes in her book "The Writing Life,""how we spend our days is, of course, how we spend our lives."

There's no short-cut to a happy life, but there are simple things we can do to help us get there.

"We have a choice in our lives, in our behavior, and in our thoughts, as to what we want to focus on and what type of people we want to be," host of "The One You Feed" podcast Eric Zimmer tells Tech Insider.

Zimmer has talked with more than 110 psychologists, mindfulness teachers, and life coaches about overcoming fear and fostering happiness. He's found happiness takes more than positive thinking — It takes constant and consistent effort to live your best life.

Here are a few strategies to start your journey today.

1. Meditate.

RAW Embed

Even if it's just for two or three minutes a day, a daily meditation practice helps you be more present, focused, and empathetic, Zimmer says. Meditation can also help you understand how your mind works and avoid mental autopilot.

"Happiness is predicated on being aware," he says. "It's important to start training that muscle."

If you're a beginner, try sitting in a quiet space for a few minutes at the same time every day. Be attentive to only what is happening in that moment, concentrating on the breath. When a thought comes up, return to the breath.

2. Set phone alarms to fight zombie scrolling.

RAW Embed

Twitter, Facebook, and Tumblr feeds are designed to get us to keep scrolling. YouTube and Netflix's autoplay features are engineered to get us to keep binging.

"We have a natural desire to distract ourselves with our phones, which is not always a bad thing, but you should be consuming something you care about," Zimmer says. "The more we are conscious about how we spend our time and do things that matter to us, the more content we will be."

We can actually use our phones to avoid mindless Internet use. If you only want to use Facebook for 10 minutes, set an alarm. When it goes off, log off immediately.

You can also set random check-ins during the day, and then ask yourself these three questions: Where am I? What am I doing? Is what I'm doing important to me?

3. Play the alphabet game to derail ruminating thoughts.

RAW Embed

If you notice you have a lot of ruminating, negative thoughts, Zimmer recommends trying the alphabet game.

Start with A, naming something you appreciate that starts with that letter. Then move to B, and do the same until you get to Z.

It's a great strategy to get yourself out of unhealthy thought patterns, Zimmer says.

"It brings your brain back and can be more effective than just positive thinking. The puzzle aspect helps gratitude stick more," he says.
