Let's face it, you probably don't know as much about your Mac as you should.

But there's hope!

We've put together some great tips and tricks that can save you time, and at the same time allow you to do some really cool things with your Mac.

From taking advantage of your Mac's hidden calculator, to discovering the tiny icon that's been right in front of your face the entire time, we've got the most important tips and tricks covered.

Feel free to share any useful shortcuts you've found too.

Take a trimmed screenshot: Tired of taking screenshots that capture much more of your screen than you'd like? Hold down Command + Shift + 4, which will change your cursor into a cross hair. After you've outlined what you want to be in the screenshot, press the Spacebar to capture.

Hidden icon in plain sight: Once you save a Word, Pages, PowerPoint, or (most) other documents, a little icon appears at the top of your toolbar, next to the document name. You can treat this like a normal file icon and drag it wherever you like, which will move the file too.

Quick tab management: If you need to get rid of too many applications running, hold command and press your tab key to cycle through the applications. Tap "Q" to quit any of the applications, or "H" to minimize.

Ernest Hemingway really loved his liquor.

He liked his Martinis dry, his Mojitos sweet, and was rumored to be drinking a quart of whiskey a day later in his life.

And now we have even more proof.

Shaun Usher  — who publishes the extraordinary site Letters Of Note— tweeted out a picture of Hemingway's postscript to a letter to Ivan Kashkin, a Russian translator and critic, in 1935.

Here it is in full:

"P.P.S. Don't you drink? I notice you speak slightingly of the bottle. I have drunk since I was fifteen and few things have given me more pleasure. When you work hard all day with your head and know you must work again the next day what else can change your ideas and make them run on a different plane like whisky? When you are cold and wet what else can warm you? Before an attack who can say anything that gives you the momentary well being that rum does? I would as soon not eat at night as not to have red wine and water. The only time it isn't good for you is when you write or when you fight. You have to do that cold. But it always helps my shooting. Modern life, too, is often a mechanical oppression and liquor is the only mechanical relief. Let me know if my books make any money and will come to Moscow and we will find somebody that drinks and drink my royalties up to end the mechanical oppression."

We recently told you how to avoid Internet snoops, and that got me thinking about online privacy in general.

Sometimes it's easy to forget that before the Internet became ubiquitous, privacy was a normal, everyday thing. People just couldn't see your stuff whenever they felt like it.

Now, however, it's important to be aware of what you're doing online — and how much of your own personal information you may be allowing others to access. 

Everyone knows (or should) to use complex passwords. But do you use your web browser's private browsing mode when checking your bank account or paying a credit card bill?

The rest of these tips should serve as a refresher and help you surf the internet safely.

When checking your bank account or paying a bill online use the incognito mode or private browsing.

Put a passcode on your computer and smartphone. If your devices fall into the wrong hands it'll be one step harder to access your information.

Put a Google alert on your name.

Putting a Google alert on your name will make sure that you always know what's being said about you online.

Its simple to set up. Start by heading to google.com/alerts.

Type in your name, and other variations of your name too. Make sure to put quotations around your name so that the search engine can look specifically for you.

After losing in the semifinals at Wimbledon three straight years, Andy Murray broke through last year to become the first Brit to reach the finals since 1938.

Now, after reaching the finals for the second straight year, Murray will try to become the first Brit to win the tournament since Fred Perry in 1936.

Of course, a lot has changed at Wimbledon in the 77 years since Perry's last of three straight Wimbledon championships.

On the next few pages we will take a look at some amazing photos that show just how much it has changed.

In 1936, Fred Perry wore pleated slacks with a belt and of course, used a wood racket

And even occasionally wore a short-sleeved sweater

Today's players still wear all-white, but now it is shorts, synthetic materials, and rackets made with materials such as graphite

It's against the rules for U.S. servicemembers to play with stray animals in war zones, but sometimes rules are for fools.

And in Iraq and Afghanistan, where the deployments have been long and arduous, having some animal companionship can offer much needed stress relief. 

Even soldiers deployed to war zones have a sensitive side.

Like this Marine gunnery sergeant in southwestern Afghanistan.

Navy Corpsmen, like the one pictured here, serve as medics to the Marines; clearly they are affectionate people.

There is nothing better than a steak done the right way.

Earlier this year we met Chef Michael Lomonaco of Porter House New York, a classic American-style steakhouse, who shared some of his key grilling tips.

He showed us how to select the right piece of meat, how long to cook it for, and how to take care of your grill.

Chef Lomonaco walked us through some of the important terms and concepts you need to understand to cook delicious steaks right at home.

The terms "prime meat" and "dry-aged" really do matter when it comes to quality.

Prime meat has a "great deal of marble or fat within the beef, the fattiness makes it so delicious," says Chef Lomonaco. It serves as a natural source of flavoring when it cooks.

Dry-aged meat is kept in a specially controlled locker.

By controlling the temperature and humidity of the space, the meat's enzymes are able to develop and interact creating more complex favors.

Specifically, Chef Lomonaco explains, "dry-aged beef has a particular flavor, a nutty aroma, and pronounced beef flavor."

In addition to the flavor, aged-beef is firmer than non-aged and has less moisture content. The reduced moisture helps tenderize the meat and concentrate the flavor. 

Because the meat is more tender is feels firmer than regular beef and this can affect the "finger test" when trying to gauge doneness. More on the "finger test" later.

You don't always need to get the most expensive cut to get a great steak.

Sure when you go to a steak house you want to get the prime, dry-aged rib-eye that you only find at the finest restaurants. But when cooking at home, a simpler cut can still get stunning results. 

Chef Lomonaco recommends skirt steaks or hanger steaks for home cooking because these cuts have a great flavor and quality and can be cooked easily on the grill or in a cast iron pan. They are also a lot cheaper than the pricier prime cuts. 

This can even be true at restaurants. New York Magazine gave its coveted top 2012 steak award to a modest $15 hanger steak in Brooklyn.

Let the meat reach room temperature before cooking.

And this goes for chicken and fish too! The meat will cook more evenly if it is the same temperature throughout.

Professional kitchens that have super high-powered grills, like Porter House NY's 1800º F grill, can cook a frozen piece of meat just fine.

But if you are cooking on your home grill (which probably maxes out at around 500-600º F) letting the meat reach an even room temp will help you control the temperature of your meat better as you cook it.

Vegas is a city that is decidedly over-the-top, so it’s no wonder that it’s host to some of the most luxurious hotel accommodations in the world.

We’ve selected five of the city’s most jaw-dropping, high-roller-worthy suites that we think embody modern Las Vegas decadence.

Forget the kitsch and tacky opulence of yore; these beauties are sleek, sophisticated, and, well, pricey.

The Villas at The Mirage, Las Vegas

The Villas at the Mirage have an affirmed reputation as havens for high-rollers and A-listers — and it’s no wonder. The private gated entrance ensures extra privacy, and each villa comes with its own heated pool, putting green, and 24-hour butler.

See more photos of Villas at the Mirage

Penthouse A at the Palms Casino Resort

This off-the-Strip hotel is known for its crazy parties and celebrity stopovers, and there are certainly A-lister-worthy accommodations on offer. Penthouse A has a fireplace, private pool on an outdoor terrace, pool table, and stunning views.

See more photos of Penthouse A

SKYLOFTS at MGM Grand

Skylofts is the luxury section of MGM Grand, offering some of the most exclusive accommodations not just within the hotel but in Vegas.

All of the rooms are one-, two-, and three-bedroom duplex lofts (they start at 1,400 square feet) with big living areas and sophisticated but understated urban decor; prices are usually upwards of $1,000 a night. High-end extras include airport transfers in a Rolls-Royce Ghost limousine.

Asiana Airlines Flight 214 from Incheon, South Korea crash landed at San Francisco International Airport (SFO). Early reports have the cause of the crash as the tail breaking off just before or during landing.

The plane caught fire, and has since been extinguished.

A passenger on the plane tweeted "I just crash landed at SFO. Tail ripped off. Most everyone seems fine. I'm ok. Surreal... "

That may unfortunately not be the case, as a KTVU source in the San Francisco Fire department said that two people have died. 

With Windows 8.1, announced last month, Microsoft has fixed a lot of the things people hated about Windows 8.

But there's one thing that it hasn't fixed: the fact that this gesture-based operating system is not intuitive.

It can take quite a bit of poking around to figure out how to navigate or perform other tasks.

We've been playing with a Microsoft Surface Pro and the Acer Iconia W3 with 8.1, table for a few weeks and discovered a bunch of "hidden" tricks.

Even closing a Windows 8 window isn't obvious ...

Microsoft says that Windows 8.1 will automatically close apps if you haven't used them for a while, but we've never experienced that.

But it can be baffling to figure out how to close a modern app, since there's no little "x" in the Window anymore.

To close a window, with one finger swipe from the top of the screen to the bottom.

You can add multiple accounts.

Windows 8 relies on lots cloud services. So every user needs to sign into the device with his/her own Microsoft account to access Microsoft's cloud storage, email, and so on.

To add multiple accounts: From the Start screen swipe the right side of the screen. Tap Settings,  tap Change PC settings, tap Accounts. Choose Other Accounts. You can create a new Microsoft account from this screen using any email you have, even Gmail.

You'll also have an option to add a child account that lets you monitor/control your kid's Internet usage.

Here's how to manage your privacy.

If you don't like the idea of an advertiser tracking your online moves, you can decide how much information Microsoft shares.

Sign into the Windows 8 device using a Microsoft account. From the Start screen swipe the right side of the screen.

Tap Settings,  tap Change PC settings, then Privacy. Decide which apps can see your location,  control your Webcam and mic. Then click on "Manage my advertising privacy preferences" and choose how much data to share with online advertisers.

On paper, Candy Crush Saga sounds incredibly dumb: switch a set of candies around in a box to match three of a kind.

It's Bejeweled, but with candy, right?

But Candy Crush Saga is currently HUGE in the mobile gaming world. It's No.3 in the Apple App Store and is the top game on Facebook, with 44 million monthly active users, according to AppData.

Candy Crush Saga is played more than 600 million times a day and is reportedly bringing in hundreds of millions of dollars to King, the creators of Candy Crush Saga.

The game only appears to be incredibly simple. In fact, it's ingeniously constructed to keep you playing against your better judgment by engaging you in a "compulsion loop." It combines ease of access, random rewards, enforced withdrawal, and constant progress in an almost never-ending stack of levels.

Here's how it's constructed.

First, the game is easy-access. No special gaming skills are required: It's a pick-up-and-play game. You can play it for a couple of minutes or for several hours. The basic idea is to match at least three candies together.

Once you've started playing, Candy Crush never leaves you alone: It's cross-platform, so you can play it on your computer, iPhone, iPad, etc. and always pick up right where you left off.

Second, you are randomly rewarded by the game. There are four different game modes to keep you on your toes. In the Moves round, you have to reach a certain score in X amount of moves. It gets increasingly harder to achieve as you progress.

Google product marketing manager Krista Seiden was on her way from San Francisco to Phoenix yesterday when she tweeted, "Hmm, seems my life has revolved around airports recently."

And then the Asiana Boeing 777 crash landed at San Francisco International airport— right in front of her.

She took some of the most dramatic early images of the crash, which she gave the media permission to use.

Her fast-thinking — and her cellphone camera — got her onto CBC News.

Here are her tweets and images, as they happened.

Seiden was waiting for her flight to Phoenix when she looked out the window. She tweeted: "Omg a plane just crashed at SFO on landing as I’m boarding my plane." She later added, "@9NEWS @PKGM yes. Plane came down and hit on its belly, immediately enveloped on smoke. Pic taken ~15 sec after crash"

"People being evacuated via the emergency slides at the plane #crash at #SFO."

"Breaking news update: smoke appears to be getting worse, lots of emergency personal at site #SFO #planecrash." She also tweeted, " Don’t know airline or plane size yet, but definitely a commercial jet. Lots of smoke. Emergency evac slides down #SFO"

Smartphones are a relatively new technology. But older people still have old-school ideas about when it's polite, or impolite, to use smartphones. 

We had Survey Monkey conduct a nationwide survey of people to see how and when people are using their smartphones. We have gathered the results here, focusing on people aged 45-60.

We previously published the results for people 18-29 years old. The results from the 45-60 group follow, and you can see that they have a much more traditional notion of when it's appropriate to use a phone.

For instance, that old piece of etiquette from the days of the hard-wired phone — that it's impolite to call when someone's likely to be eating dinner — is still a current standard for middle-aged people, even though young people just don't care.

It's slightly acceptable to answer a phone call at dinner, but you probably shouldn't do it at all.

Business calls are a little bit better, but are still only "slightly" acceptable.

Facebook, though, is a different story altogether. Don't even think about checking it.

From fresh, crunchy locusts to eggs hard-boiled in urine, cultural ideas about what constitutes a delicacy vary drastically by region.

But the world is getting smaller, and ideas about what's acceptable to eat are changing. The U.N. recently told people to suck it up and learn to eat bugs, which are filled with protein and fiber.

And in the wake of the January's horse meat scandal in the U.K., many people wondered aloud: Why don't we eat horses when we eat cows and other similar mammals?

We found 18 amazing pictures of some of the most extreme cuisines from around the world, and it turns out that people living in Western nations are pretty picky when it comes to what they will and won't put on their plates.

Be warned: Some photos are not for the faint of heart (or stomach).

The adaptation of Max Brooks' "World War Z" is currently earning bank at the box office, here are 16 of the biggest book-to-movie projects.

*All figures are total domestic grosses, not adjusted for inflation.

"Jaws" (1975): The first Steven Spielberg-directed movie on the list made $260 million and is based on the Peter Benchley novel with the same name.

"How the Grinch Stole Christmas" (2000): The Dr. Seuss classic is the only holiday-oriented picture on the list, besting "Jaws" by less than $50,000.

The Chronicles of Narnia: The Lion, The Witch, and the Wardrobe (2005): The first of a series of films based on the work of C.S. Lewis, "The Chronicles of Narnia" grossed $291 million.

Every banker, trader, broker etc. we've talked to will barely glance at their Blackberry, let alone their Bloomberg screens over the next couple of days.

Everyone is in holiday mode.

So while you're kicking it with your loved ones over BBQ and what not, feel free to relax with one of these movies. They'll serve as a reminder for why you actually love working on Wall Street, and why you can't wait for all the stupid relaxing to be over, obviously.

The 25th Hour (2002)

In a sentence: The broker scene, that's all you need to see "...when you become a cowboy, that's when I draw the line."

Plot: Okay, not totally a Wall Street movie, but when there's a full-on scene about trading on employment numbers in a movie, it makes the list. Directed by Spike Lee, the movie is mostly about a man's last day of freedom before going to jail for selling drugs.

Quants: The Alchemists Of Wall Street (2010)

In a sentence: A rare look inside the minds of mathematical geniuses who have invented financial models that have both destroyed and made Wall Street.

Plot: Quants is 45-minute documentary on the inner-workings of quantitative analysts on Wall Street.  If you'd like to watch it, it's embedded below via YouTube.

Money, Power and Wall Street (2012)

In a sentence: A Frontline documentary that breaks down our latest doom machine.

Plot: The financial crisis comes alive as Frontline's expert documentarians interview the people that watched it all fall down, from journalists to regulators, to Wall Streeters. This is a two parter.

Men's Wearhouse made headlines recently when it decided to can its TV spokesman and founder George Zimmer.

This type of thing happens all the time, says Noam Wasserman, a professor at Harvard Business School. Sometimes their passion detracts from their management skills and they aren't suited to run the companies their start-ups grow into.

Here are seven more founders who learned the hard way.

Martin Eberhard, Tesla

Tesla Motors might be synonymous with the name Elon Musk, but the company has two founders.

In 2007, Tesla fired Martin Eberhard from his post as president, but apparently signing a"non-disparagement agreement" didn't stop him from sounding off on the company.

In 2009, Eberhard sued Musk for libel and breach of contract, as well as taking credit for developing Tesla’s Roadster. The suit also claimed Tesla had withheld his severance pay as a consequence of violating the non-disparagement clause.

Danny Zappin, Maker Studios

Maker Studios' co-founder and recent CEO Daniel Zappin alleges the companybreached his contract by pushing him out.

According to Variety, which first broke the story, the lawsuit says "Maker Studios and other defendants 'conspired and agreed to use their power to line their pockets with Maker’s assets, to deny Mr. Zappin, Maker’s then chief executive officer (‘CEO’), of all of his powers, and to gut the rights of common stock shareholders to control Maker and its corporate activities.'"

Last December, Time Warner took a stake in Maker Studios, leading a $36 million investment.

Andrew Mason, Groupon

Despite being fired, Andrew Mason still took the high road.

Mason broke the news in a farewell letterto Groupon employees, in which he took responsibility for the company's failings, including its disappointing earnings since going public in 2011.

"As CEO, I am accountable," he wrote. "You are doing amazing things at Groupon, and you deserve the outside world to give you a second chance. I'm getting in the way of that."

On July 2, Mason will release a seven-track record of "motivational business music" called Hardly Workin'.

Today, Facebook is finally launching its new Graph Search feature.

The new search tool uses your Facebook connections and interests to come up with relevant results for people, photos, places, and interests.

These are generally results for which a regular Web search would come up empty — like "places I visited in 2010" or "photos of my friends taken before 1980" or "restaurants my friends like."

(In fact, Facebook struggled with naming its new search feature, fearing that anything with "search" in the name would make people think of a Web search engine like Google.)

We've been playing with Graph Search for the past few months and its easy to see why naming the product was so hard. This is not Google Web search—it's something completely different.

The interface strongly guides users to doing these kinds of searches, responding with plain-English suggestions for questions.

Here's what you can expect to experience with Graph Search starting today.

Thanks to Owen Thomas who contributed to this article.

When you first log in, Graph Search prompts you to take a tour.

Suggestions for searches come from profile data—like the college you attended.

From there, Graph Search tries to help you narrow your search.

Walmart, America's biggest employer, is merely the 10th biggest brand advertiser in the U.S. according to data gathered by Kantar and supplied to Ad Age.

Some of the usual suspects have also made the top 10 — McDonald's, Macy's and T-Mobile for instance.

But there are a few big brands who didn't make the cut.

Apple was merely the 12th biggest spender, at $662 million. Samsung spent $597 million, and came at No. 15 in the ranking.

10. Walmart: $690 million. Walmart is a nimble juggernaut, and seemingly nothing can stop it. It most recently severed ties to Paula Deen to maintain its squeaky clean brand image.

9. Macy's: $762 million. A huge portion of the department store's branding is around entertainment, such as Macy's July 4 fireworks in New York.

8. T-Mobile: $773 million. The wireless service recently ditched the beloved T-Mobile girl in pink to hitch its wagon to the iPhone 5 and a no-contract deal for new signups.

Clinical psychologist Dr. Meg Jay doesn't subscribe to the theory that your 20s are a throwaway time to just have fun and decide what you want to be when you grow up.

While popular media often depicts 20-somethings as aimless wanderers lounging in extended adolescence, the truth, according to Jay, is that your 20s are your defining decade.

In fact, that's the title of her new book,"The Defining Decade: Why Your Twenties Matter—and How to Make the Most of Them Now" and the inspiration for her TED talk, which proclaim that 30 is not the new 20, stressing the importance of that crucial time period post-college, especially when it comes to your career.

We got Jay on the phone to get her advice on nine of the most common myths about your 20s, and what you should do instead. If you've ever considered bailing on your job or your "temporary" barista job has stretched to three years, you're going to want to hear this.

Myth 1: Your twenties don't count.

Despite their best efforts, 20-somethings have been hindered by the recession and difficult economic climate. From saving money to borrowing money, Gen Y lags behind their parents and grandparents. But that doesn't mean they get to take a time out.

“Your 20s are the time to make some moves,” Jay says. “It's a unique, potentially transformative time. It ends up being more important than it feels.”

If you're putting off starting your life ... don't. It's time to start making deliberate choices in your job, your city and even your love life to set yourself up for the life you want in your thirties. As Jay said to one young woman in her book who said that her choices before age 30 were just practice: "Consider what part you're rehearsing to play."

Myth 2: You need to know exactly what you want to do.

Too many 20-somethings think they need to figure out what they want to be when they grow up before landing an actual job. Instead, says Jay, your 20s are the ideal decade to build what she calls "identity capital"—little bits of experience you collect that coalesce into a solid identity over time.

For example, rather than holding out for your absolute dream job, it's O.K. to take a job that isn’t ideal, as long as there's something about the position that could lead to another, better opportunity down the road. It's also fine if it's something a little unconventional. “I always tell my clients to take the job that's going to make people lean forward and say, ‘Tell me about that!’” she says.

Long before becoming a successful psychologist, Jay was an Outward Bound instructor, which her future interviewers found cool. “I was actually the only person in my graduate school class at Berkeley who didn't go to an Ivy for undergrad, but with Outward Bound in my pocket, I didn't need the Ivy distinction," she says.

She too, went through a 20-something period of being "underemployed," but made a point of upping her identity capital by choosing such an interesting part-time gig. If you need to make ends meet as a nanny or barista for a time, fine, but also try to find a way to get more high-profile experiences on your résumé. As she writes in her book, no one will start off an interview with, "So tell me about being a nanny."

Myth 3: You can do anything you want.

Before you get stars in your eyes, you should be realistic about your skills and goals. “Sometimes people get in their 20s and hear, ‘Oh my God, you can do anything you want in the whole wide world!’” Jay says. “That's overwhelming, and it's not true."

In her book, she discusses psychoanalyst Christopher Bollas' idea of "unthought knowns"—things we know about ourselves but forget or suppress, like a childhood dream of working with animals or an aptitude for physics that was abandoned post–high school. To keep from being overwhelmed by "endless" possibilities, put together a handful of concrete plans you could pursue, based on your unthought knowns.

Carriers and manufacturers are offering big discounts on top-tier smartphones this summer in preparation for new devices launching this fall.

Plus, there are a bunch of relatively new devices that have launched in recent months from just about every big name in the smartphone business.

Here's what you should be looking at. 

Note: We update this list approximately once a month. Our rankings are based on a variety of factors including design, software and hardware features, content selection, and price. We only consider phones that are on sale in the US at the time of publication. You can see last month's smartphone rankings here.

#15 BlackBerry Q10

The Q10 is BlackBerry's first device running the company's new BlackBerry 10 operating system with a physical keyboard. 

It's a good phone, but you should only consider buying it if having a keyboard is the only feature you really care about. New BlackBerry 10 phones don't have a good app selection, and the Q10's touchscreen is much smaller than other top-tier phones.

Click here for the full review of the BlackBerry Q10 >

Price: $200 on Verizon, $200 on AT&T (pre-order), $100 down plus $20 per month for 24 months on T-Mobile. Available soon on Sprint. 

#14 iPhone 4S

Even though the iPhone 4S is approaching its second birthday, it's still a pretty good phone if you're on a budget. Plus you get access to the best ecosystem of apps, games, movies, and music from Apple.

Price: Starts at $99 with a two-year contract on most carriers, $69 down on T-Mobile. (Sprint, Verizon, T-Mobile, or AT&T)

#13 Samsung Galaxy S III

Samsung still sells its flagship phone from last year, the Galaxy S III. The phone is nearly identical to the current flagship Galaxy S4, but has a slightly smaller screen, thicker body, and fewer software features. 

Click here for our full Samsung Galaxy S III review >

Price: Price varies by carrier, but you can get it for $100 or less with a two-year contract many places. (Verizon, AT&T, Sprint, and T-Mobile)
