When it comes to waterproof cameras, drastic updates are few and far between. Nikon's AW line of cameras is no exception: from year to year, they generally don't change much at all.

On paper, that appears to be the case again in 2015. But this year’s Nikon Coolpix AW130 (MSRP $349.95) takes last year's AW120, and rectifies its biggest omission: a grip.

That might not sound like much, but the grip results in a camera that's easier to hold and use. While it won’t set any performance records, this is a point-and-shoot you can confidently take on any adventure—rain or shine. In addition, several key changes take this camera from mere refresh to a shooter that's worthy of a new model number.

The user experience will be familiar to anyone who’s used an AW before, thanks to its slippery aluminum exterior, and a set of easy to navigate menus.

Unquestionably, the selling point of this camera is durability. Not only can it go on dives 100 feet underwater, but can also withstand temperatures down to 14˚F, and drops of up to 7 feet. The added grip is a long overdue upgrade, because without it the camera has a tendency to slip out of your fingers when wet.

Taking a peek inside that tough exterior, you'll find a 16-megapixel, 1/2.3-inch sensor behind a 5x zoom 4.3-21.5mm (24-120mm full-frame equivalent) f/2.8-4.9 lens. The glass isn’t spectacular, but it’s more than adequate, and offers more flexibility with your shots.

One flaw with this camera is its dim screen — it’s difficult to see in direct sunlight, which is a shame since you're likely to use it outdoors. There's not really a good remedy, so you'll often be left to point, shoot, and hope.

When it comes to performance, the AW130 is able to hold its own in a crowded sea of waterproof shooters. There are a bunch of limitations the waterproof, unibody design imposes upon a camera—but the AW130 handles them gracefully.

With that in mind, its positives are substantial: color performance is great, and sharpness is decent. However, smartphone cameras are starting to catch up to point and shoots, and the bump in performance you'd get from buying the AW130 over your smartphone isn't much. You’re buying this camera because it can go where your smartphone can't.

The camera's environment will also play a role in how well your shots come out. For example, deep water will restrict how much light is available. Same goes for any low-light situation. For best results, I suggest keeping your auto-ISO setting to capped out at ISO 800 to prevent excessive noise.

So why buy this over another waterproof camera? The answer lies in the features, including its freshly upgraded software. For instance, the new scene modes are exhaustive and fun. You can add a handful of effects to your snaps, and even use one of 22 shooting modes to get the right settings in any situation. On top of that, you can also shoot timelapse videos if you have a tripod (and are willing to wait a while).

Like the other cameras in Nikon's AW line—this camera has onboard WiFi to pair with your smartphone. Using the app, you can also use your phone to remotely shoot pictures with the AW130.

This camera makes good use of its onboard GPS, with a points-of-interest feature that lets you look at a bird's-eye-view of areas you're about to explore. In addition to the ability to geotag your shots, you can also map out your vacations using Nikon's freeViewNX 2 software to show people where each snap was taken (you’ll want this at Gettysburg).

Smartphones have come a long way, and the appeal of point and shoots is starting to rely more and more on qualities that fragile little phones just can't provide. In the AW130’s case, that means its extreme durability gives it an edge over your phone.

It's got all the features a point and shoot needs to stay relevant in a world of do-everything smartphones, while offering extreme water, dust, and shockproofing. This is a reliable camera that will shoot even when covered in pond muck and mud. Thanks to its added grip and better software, it’s remedied a lot of the concerns we had with last year’s AW120.

The AW130 sits near the top of the toughcam heap, but there are always alternatives. Last year's Olympus TG-3 is a better waterproof camera—though it can't dive as far as the AW130. If you're looking for a little more power to take with you, Nikon's 1 AW1 is the only interchangeable-lens toughcam for consumers, but it's more fragile than the AW130. You could also go bargain-bin diving online and get last year's Nikon AW120 at a decent discount—it's virtually the same as the AW130, minus NFC and a grip.

Q. I hate Windows 7. I'm really looking forward to the Windows 10. When will I be able to upgrade?

A. While Windows 10 is launching July 29, very few people are going to actually get the upgrade that day. Microsoft is rolling out Windows

10 in stages starting with people in the Insider program. After 10 is working well for them, it will go to people who reserved a copy using the reservation system in Windows 7 and 8. Even that's going to take a while because Microsoft is upgrading small groups one at a time. If you aren't an Insider and didn't reserve your copy, it's going to be a while, expect months.

Find out why Microsoft chose to do things this way and how you can move up the list.

Print from your smartphone

Q. Like a recent caller on your national radio show, my computer died and between my smartphone and my tablet I don't miss it that much. But how do I print things? I used to hear you on Armed Forces Radio when I was stationed in Iraq. You were a breath of fresh air from home. Thank you for your support of our military!

A. First, thank you and your family for serving. We appreciate your sacrifices. Now, both Apple and Android gadgets include wireless printing systems. Apple has AirPrintand Android has Google Cloud Print. If you have a compatible wireless printer on your network, your gadget should detect it, connect and let you print with a tap. There are also third-party apps like Paper Hammermill (Android, Apple; Free) that work with a wider range of printers. Of course, it isn't always as easy as it should be. Click here for step-by-step instructions for setting up and using these services to print from your mobile gadgets.

New iPhone rumors

Q. I'm thinking about upgrading to an iPhone 6, but isn't a new iPhone coming soon?

A. The next iPhone, which could be the iPhone 6s or iPhone 7, is rumored to have some interesting goodies. The biggest addition is a "Force Touch" display that not only registers touch, but pressure. That means you can make different things happen based on how hard you tap or press the screen. There should also be a faster processor, more storage space, and possibly a 12 megapixel camera to replace the current 8MP version. That's just the beginning; find out more about the next iPhone's rumored features. And in case you're curious, Apple announced new iPods too.

An actual use for selfies

Q. I don't get the whole selfie thing, but my daughter and her friends take them all day long. What do you think this is going to do to society in the future?

A. The selfie craze isn't dying down, and some companies have decided to accommodate the selfie-loving generation. MasterCard, for example, is starting a trial of a system that lets you confirm payments by taking a selfie instead of typing in complex passwords. It's actually just a fun way to say "facial recognition." So far, facial recognition hasn't proved to be too secure on mobile gadgets, but MasterCard thinks it can make it work. Learn more about how this "selfie" system works and see it in action.

Daughter calls Mom paranoid

Q. My daughter is constantly posting her vacation pictures on Facebook. I tell her this isn't safe. She says I am paranoid.

A. Tell your daughter this: Over 75 percent of convicted burglars admitted that they use social media to target victims. These criminals only need a rough idea of where you live and access to Google Street View to start casing your home. Depending on where she posts her photos, she could also be revealing her exact location. Suggest that she wait until she's safely home to post vacation stories. And instead of sharing potentially sensitive photos across social networks, create a private photo album on a site likeFlickr or Google Photos. Click here for a tip on my site that details how precisely burglars use social media and how to avoid being their next victim. Send her the link.

Bonus Question: Apple Watch woes

Q. I bought the Apple Watch and I hardly use it. I like the idea of a computerized watch. Maybe I just need a different one. Can you help out?

A. I hear you. I don't wear my Apple Watch either. There are several other makes and models to choose from including LG, Samsung, Sony, Pebble, etc. The differences between them span display type and size, battery life, voice controls, whether you need a smartphone to use, and more. But I did the heavy lifting and made it easy for you. Click here for my SmartWatch Comparison Chart.

The Federal Aviation Administration is investigating two incidents in which airplanes spotted a drone flying near them as they were landing at John F. Kennedy International Airport, one of the nation's busiest airports.

One of the airplanes reportedly came within 100 feet of the unmanned aircraft.

Delta Flight 407, an MD-80 en route from Orlando, was preparing to land at 4:55 p.m. Friday at JFK when it spotted a drone flying at 100 feet about a quarter-mile from the aircraft.

The pilot did not take evasive action, the FAA said in an emailed statement. Delta spokesman Anthony Blacks said the flight carrying 149 passengers and five crew landed safely with no injuries.

JetBlue Flight 1834, an Airbus A-320, was arriving from Port-au-Prince, Haiti, earlier that day at 2:24 p.m. when the pilot also reported seeing a drone near the airport. The pilot did not take evasive action to avoid the drone, the FAA said. In the audio recording, the cockpit says the drone passed just below the plane's nose when the plane was flying at an altitude of about 800 to 900 feet.

Both airplanes landed safely. The FAA said it's investigating the incidents. It's unclear whether they were related.

JetBlue spokeswoman Kate McMillan says the airline had not confirmed the report with the crew of the aircraft.

Drones are not supposed to fly within 5 miles of an airport without notifying the control tower. They are also not supposed to fly above 400 feet.

Drones flying too close to commercial flights threaten large aircraft as they can be sucked into the engine or crash into the cockpit window, Phil Derner of NYCaviation.com told CNN affiliate WPIX.

Dave Mathewson, executive director of the Academy of Model Aeronautics, said, "No unmanned aircraft should be flying in a way that poses a risk to manned aircraft."

"The key to safe and responsible operation is education, as many newcomers to the technology don't know where they should and should not fly," Mathewson said in a statement.

Have you ever clicked "Send" on an email and regretted it a fraction of a second later? Whether you were angry and typed something you shouldn't have, clicked "Reply All" when you wanted "Reply," or just accidentally clicked the "Send" button before the email was finished, your first instinct is to find and click an "Oops!" button. Unfortunately, there is no such button for email ... or is there?

While I can't tell you how to unsend email you might have sent already, I can give you four options to set up your email so you can undo them in the future. Taking a few minutes now can save you a lot of embarrassment later.

Gmail 'Undo Send'

Google's Gmail is an incredibly popular email system thanks to its powerful and customizable inbox. It also has more features on the back end than you can shake a stick at, and it's adding more all the time.

One feature Gmail has had for years is "Undo Send," but it was experimental and buried away. Now, it's front and center, and you just need to enable it.

In your Gmail account, click the gear icon in the upper-right corner and choose "Settings." On the "General" tab, scroll down and find "Undo Send." Click the checkbox for "Enable Undo Send" and choose the cancellation period.

You can choose a cancellation period of 5, 10, 20 or 30 seconds. This is how long you have to realize that you didn't mean to send that email and call it back before it gets delivered. Once you have that set, scroll down to the bottom of the screen and click the "Save Changes" button.

Now when you click the "Send" button on a message, you'll see a message appear at the top of your Google inbox with an "Undo" link. As long as the message is on the screen, you can click the "Undo" link and the email will reappear ready for editing or deleting.

Of course, maybe you want a grace period longer than 30 seconds or you use a different email service. I've got something for you, too.

Browser plug-ins

There are a few browser plug-ins that offer unsending features. The first one we're going to look at is Criptext. Right now, it's just for Chrome and Safari, but Firefox and Outlook program versions are in development.

When you enable Criptext on an email, it encrypts the message and any attachments, tracks it so you know when it's been opened, and gives you the option to "recall" it. You can also set messages to expire after a certain amount of time.

UnSend.it is a service that works with more browsers and email services than Criptext. It does everything Criptext does, except encryption. You will also need to configure your email service to run through UnSend.it's servers.

Once that's done, you can send email and attachments to anyone. If you decide to unsend the email, just click a button in your email service and they won't see it anymore. You can also track when someone opens the message or set it to self destruct after an amount of time.

Both of these services work by turning the text of your message into an image, then sending that image on to your recipient. Because the message is served from their servers, they can delete the image and it will disappear from your recipient's inbox.

The email will still be there, but it will be blank. Unless your recipient took a screenshot, they won't have the information. If you really want to take things to another level, however, keep reading.

Secure messaging

Most free messaging systems aren't really that secure, which is why a former NSA employee decided to take matters into his own hands. The result is called Virtru.

Virtru is a plug-in for Firefox and Chrome that works with Gmail, Yahoo and Outlook.com. There's also a plug-in for Outlook 2010 and 2013, along with apps for Apple and Android.

The free version of Virtru lets you send secure messages to anyone. If the other person has Virtru, they can open the message in their regular email. Otherwise they'll need to get Virtru's free Web viewer.

If you upgrade to Virtru Pro for $2 a month, it adds message revoking and expiring, along with the ability to see and control message forwarding. Learn more about Virtru's features and step-by-step instructions on how to use it.

NEW YORK — Ride-hailing company Uber just completed a round of funding that values them at a whopping $51 billion — or more than four times the value of rental car companies Hertz and Avis combined.

The latest funding came from Microsoft and the investment arm of Indian media conglomerate Bennett Coleman & Co., according to the Wall Street Journal, citing anonymous sources. Uber raised close to $1 billion in the latest round, bringing its total funding to more than $5 billion, the WSJ reported.

Uber has 3.5 billion shares outstanding, according to documents filed with Delaware's Secretary of State, where it is incorporated.

"We filed to authorize this new funding more than two months ago" Uber said in an e-mailed statement. "We aren’t commenting on additional speculation."

Hertz is valued at $7.8 billion. Avis Budget Group, which is also publicly traded, is valued at $4.6 billion.

Uber carries the loftiest start-up valuation in an already frothy tech economy, beating out room rental company Airbnb, which is valued at $25 billion, and Snapchat at roughly $15 billion.

Investors have been lured by the company's fast-paced growth. Uber, which was founded in San Francisco in 2009, is doing business in 58 countries across Europe, Asia and the Middle East. The company recently said it plans to invest $1 billion to expand in India.

Uber is not without risks, however, including challenges from workers over their status as independent contractors.

The company has long kept its expenses down by claiming that it's merely a technology company matching drivers with riders, not a car service company with vehicles to maintain. The saddles drivers with bulk of expenses such as maintenance, insurance, gas and the vehicles themselves.

Some employees have sued to gain employee status, a designation that could substantially increase the company's costs.

Uber has also faced opposition in cities like Paris, because the service matches passengers with drivers who don't have the proper licenses. In New York, some local politicians have expressed concern the impact of Uber's growth on already congested and polluted streets.

Last week a proposed cap on Uber and other for-hire vehicles in New York was put on ice after the start-up agreed to "not flood the streets" until questions about the impact of its growth on traffic can be determined.

A flying DeLorean?! No, just another Terrafugia car-plane concept

While the likes of Google focus on driverless cars, Terrafugia continues to look much further into the future with flying cars.

The company has been talking about its heli-car hybrid the TF-X since 2013 and has just released a video showing its new exterior design in action.


Now for the first time, Terrafugia has announced that a one-tenth scale model will be tested at the MIT Wright Brothers wind tunnel.

"The wind tunnel test model will be used to measure drag, lift and thrust forces while simulating hovering flight, transitioning to forward flight and full forward flight," Terrafugia said.

The video shows the TF-X leaving a garage and taking off from a landing pad. It's equipped with twin electric motor pods, two wings and two helicopter-style propellers.

Four passengers can be carried a maximum of 500 miles, while the TF-X is capable of flying up to 200mph.

Unfortunately, Terrafugia predicts that development of the heli-car hybrid will take 8-12 years.
