Everyone who drives should know how to use a car jack in case of a flat tire or blowout. Check your owner's manual to find out where your car jack and spare tire are located. In most cases, they are somewhere in the rear of the car. The video shows us how to use a telescoping jack, though the more common type of jack requires a scissor motion to raise the car and lifts from the side rail. The telescoping jack lifts from the axel and to raise the jack you need to insert the rod into the hole n...

There are a lot of great features for your iPhone with iOS 18, released Sept. 16, but one of the coolest features is also one of the simplest and most satisfying — one that you'll notice every day you use your iPhone. And for now, it's an iPhone exclusive, so you won't get the same gratifying experience on an iPad with iPadOS 18.
The enterprise-focused category of augmented reality doesn't often get the headlines due to its relatively sedate profile as a mostly factory floor and training-based tool.
As great as Macs are, they're often limited by the apps you have installed. Your computer might have the processing power to render a 4-hour movie in the time it takes you to have lunch, but if you don't have the right apps, you're not putting all that power to use. The All-Star Mac Bundle Ft. Parallels Pro gives you access to programs that will put your Mac to use and give you the best functionality out of it, and right now this whole bundle is on sale for $49.99.
Apple's exclusive chat services, iMessage and FaceTime, force many of us to stay locked into iOS, iPadOS, and macOS to communicate with other Apple users, so chatting with Android-using friends means SMS texts, third-party messaging apps, and third-party video chat services. However, Apple is breaking boundaries with iOS 15 so that we can FaceTime with Android, Linux, and Windows users.
It's no secret that Apple and Spotify haven't exactly gotten along in the past, but things are looking better than ever in iOS 14.5.
A successful startup needs more than a good idea. To get your startup off the ground, you need to know how to make a plan, fund it, and market it. Trying to learn how to do all of that on your own is impractical and unnecessary.
Using a virtual private network (VPN) is one of the safest ways to ensure your identity and data remain secure. Choosing one from the hundreds of services that now exist is another story. How do you tell which VPN truly provides the best protection at a great price?
Post-exploitation is often not quite as exciting as popping the initial shell, but it's a crucial phase for gathering data and further privilege escalation. Once a target is compromised, there's a lot of information to find and sift through. Luckily, there are tools available that can make the process easy. One such tool is Postenum.
We're glued to the news now more than ever, but our "free press" isn't necessarily free of charge. Cable news outlets like CNN and MSNBC are locked behind expensive cable TV packages and cord-cutting streaming subscriptions such as Sling TV and Hulu + Live TV. Luckily, there are plenty of alternatives to get your TV news fix, free of any payment, account, or commitment.
There's only so much Netflix and TikTok a person can take in quarantine before they've had enough. We've only just started our stay-at-home lifestyle, but already TV and movies are getting old. The COVID-19 lockdown doesn't just have to be a mindless watch party, so why not take the time to learn a new language?
Hey, you, still stuck at home? Cheer up, today is the first day of spring. Yes, really. And since you're probably locked in on TV, we're guessing you need a break from some of the less than sunshiney news reports rolling in. Well, no worries, because there's actually some good news to report.
Google is known for merging older products into a new one's ecosystem for ease of use. The transition can take time, and that's the case with the old Google Wifi system now that Nest Wifi is out. Google is working on phasing out the dedicated Google Wifi app in favor of using the Google Home app for all your IoT needs.
Nearly every connection to the internet is dependent on the Domain Name System. DNS, as it's more commonly called, translates domain names like gadgethacks.com into IP addresses, which is what network devices use to route data. The problem with DNS servers is that they don't have your privacy in mind.
We might never truly know all of the colors behind old and classic black-and-white photos, but thanks to technology, we can get a pretty accurate colorization. Although Photoshop is a popular way to colorize these images, you can now use your iPhone, along with a nifty shortcut, to transform and give new life to vintage photos.
Web application firewalls are one of the strongest defenses a web app has, but they can be vulnerable if the firewall version used is known to an attacker. Understanding which firewall a target is using can be the first step to a hacker discovering how to get past it — and what defenses are in place on a target. And the tools Wafw00f and Nmap make fingerprinting firewalls easy.
I've been using the Galaxy Note 10+ as my daily driver for a while now. I love it, but as with any phone, it loses its pizzazz after a while. But since it's an Android phone, there's always a way to add fresh features and functionality to the UI.
Another year, another battle between Samsung and Apple. We recently saw what Samsung is bringing to the table this year with the release of the Galaxy Note 10+, and now it's Apple's turn. For those who want a truly large device, Apple is offering the iPhone 11 Pro Max. Let's see how they match up.
Samsung decided to shake things up this year. In the past, the Galaxy Note series was one large phone. This year, it's two phones: the Galaxy Note 10 and Note 10+. So for the first time in a long time, we can compare the latest standard iPhone, the 11 Pro, to a Galaxy Note device.
iPhones with Face ID all retail for at least $999, which many still believe is just too much for a smartphone. But that's okay, because Apple just introduced the iPhone 11 for roughly $700. It's not necessarily the best value, though, because the iPhone 11 already has some stiff competition in this price range.
You may have recently seen a plethora of Instagram users, including celebrities and politicians, sharing a screenshot declaring that the platform will implement a new "rule" where it would own and could use your photos and videos however it wishes. The screenshots are part of an internet hoax, one that's been around in one way or another since 2012, but what can Instagram actually do with your media?
Every fall, we can expect a few things: leaves changing colors, cooler temperatures, and Samsung and Apple releasing new phones that fanboys and fangirls will argue about until the following year. This year, Samsung is mixing it up, releasing two phones in the Galaxy Note series. Let's see how the larger phones compare.
In Apple Music, loving and disliking songs is a great way to teach Apple's subscription service what type of tunes you like and which you don't. While it also seems like it should be an excellent way to keep track of songs you enjoy in the wild, there's no clear way to view all of your loved tracks in one convenient list. There is a way, however, but easy it is not.
As part of the iOS 11 update, Apple added a document scanner function that creates high-quality digital copies of physical documents, but it was only available inside the Notes app. With iOS 13, Apple has built its scanner right into the Files app, enabling you to quickly create PDFs with your iPhone and do more with them.
Phone numbers often contain clues to the owner's identity and can bring up a lot of data during an OSINT investigation. Starting with a phone number, we can search through a large number of online databases with only a few clicks to discover information about a phone number. It can include the carrier, the owner's name and address, and even connected online accounts.
The OnePlus 7 Pro is definitely a beast on paper. With a specs page that ticks virtually every box and a price point that undercuts the competition by hundreds of dollars, it's hard to overlook this phone. But before you get too excited, know that OnePlus has repeatedly shown to be misleading with their official specs.
News+ is Apple's new digital subscription service for written media that costs $9.99 per month. There is a free trial offered for one month, but you'll start getting charged the monthly fee as soon as your 30 days are up. While it's not very obvious, there is a way to cancel the auto-renewal right before you get charged.
In 2019, Sony is mixing up its design, attempting to stand out among the sea of familiarity. Instead of emulating Samsung with punch hole cameras, they decided to target a rare section of the market, content consumers. There's the Xperia 1 for those who want the best, and the Xperia 10 and 10 Plus for the budget crowd.
One of the best things about Android is the ability to customize every aspect of your device to make it your own. However, unless you have prior knowledge or experience with every single setting available to you, you might have missed a few critical features without even knowing it. Some settings are easy to find, while others might be tucked away in another menu of their own.
Similar to last year, LG is mixing up its releases. Instead of the G series in the first half of the year and the V series in the second half, LG is releasing both heavy hitters together. However, unlike last year, this is a true upgrade from its predecessor, the LG V50 ThinQ 5G.
After months of waiting, it looks like HMD has finally answered the call. Nokia's parent company is finally releasing a true flagship phone — one that isn't just an enhanced version of a previous phone and actually brings something new to the table. That phone is the Nokia 9 PureView.
With Apple releasing the iPhone XR, it appears Samsung is looking to challenge this "budget flagship" option head-on. They brought their usual two phone releases this year, but also threw in another three for a total of five phones, including the Samsung Galaxy S10e. And for many, this might be the option to look at.
With the best selling phone on Amazon in 2018, Lenovo had big shoes to fill when making the successor of the Moto G6. Fortunately, Lenovo was up to the task. The Moto G7 continues to provide a high performance-to-price ratio, offering a worthwhile upgrade for G6 users while remaining budget friendly.
In about 27% of all car crashes, someone was using their cell phone. You may think texting is the big problem here, but many fail to realize that even the smallest smartphone interaction could spell disaster. Thankfully, Google Maps has rolled out an overdue feature that'll help ensure a safer drive.
