If you were upset about "Friends" leaving Netflix, fret no more. The entire series, all eight Harry Potter movies, as well as HBO's massive catalog, are now available as part of HBO Max. If you're already an HBO Now subscriber, however, it can be a bit confusing to know how to switch over to this brand new service. Here's how.
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?
With many office workers in the US being asked to work from home if their job allows, Magic Leap's customary updates for the Lumin OS and Lumin SDK brings some help to keep distributed workforces connected.

We've all seen the login pages that allow you to log in to third-party accounts using your credentials from Facebook, Google, or Twitter. It saves you the trouble of creating another account and remembering more passwords — but it can also become a privacy and security issue, which is why Apple created the "Sign in with Apple" feature for iOS 13.
Over the past year, Magic Leap has teased its cross-platform vision of the AR cloud, which it dubs the Magicverse. While the company shared a timeline for its debut next year, it also served up new developer tools for the present.
Fast-food chain Jack in the Box has decided to put an augmented reality twist on the traditional sweepstakes promotion by employing the immersive powers of Snapchat.
KeePassX, 1Password, and LastPass are effective against keyloggers, phishing, and database breaches, but passwords managers rely on the operating system's clipboard to securely move credentials from the password vault to the web browser. It's within these few seconds that an attacker can dump the clipboard contents and exfiltrate passwords.
A hacker with privileged access to a Windows 10 computer can configure it to act as a web proxy, which allows the attacker to target devices and services on the network through the compromised computer. The probes and attacks appear to originate from the Windows 10 computer, making it difficult to detect the attacker's actual location.
Anyone who has been within a block of any wireless brick and mortar store or tech conference in the last couple of years has no doubt seen banners, posters, and videos promoting 5G high-speed wireless services on the way.
NetBIOS is a service that allows for communication over a network and is often used to join a domain and legacy applications. It is an older technology but still used in some environments today. Since it is an unsecured protocol, it can often be a good starting point when attacking a network. Scanning for NetBIOS shares with NBTScan and the Nmap Scripting Engine is a good way to begin.
The ability for apps and devices to determine the precise location of physical and virtual objects in space is a key component of augmented reality experiences, and the latest advancements in Bluetooth technology may have a hand in facilitating such location services in the near future.
After building its business on virtual reality, Jaunt is leaving the technology behind to focus on building tools for creating augmented reality content.

With tons of titles to choose from on the iOS App Store, you'll never be lacking when it comes zombie shooters. Unfortunately, the same can't be said if you're more interested in base-building and defending against the undead. PlayStack aims to change this, and they've soft-launched Survival City in the Philippines for further development. With a simple hack, you can try the game yourself right now.
Google has started blocking certain devices from accessing the Google Play Store and other Google services. This is part of an effort to clamp down on OEMs that skirt its certification requirements, but now millions of phones have been uncertified to download or update Google apps. Fortunately, there are a few workarounds.
Apple has tools built into iOS to help parents monitor the iPhone habits of their children. However, those same tools can be used by everyday iPhone owners to both hide apps they don't care about, as well as restrict features they don't need or that infringe on privacy. Whether you fit into one category or the other, all iPhone users can benefit from the "Restrictions" feature.
No matter what your holiday preference, you're probably aware that Christmas is now just days away. By now, you've already decked your halls with boughs of holly (either physically or virtually), thanks to our last holiday app roundup.
There was a time when building a website required coding knowledge. Eventually, software came along that made the process easier, and then services like Squarespace made it dead simple for even a technical novice to design a website.
Null Byte users have often requested video content, but the question has always been what format would best serve our community. This week, we partnered with Null Space Labs, a hackerspace in Los Angeles, to test the waters by hosting a series of talks on ethical hacking for students in Pasadena Computer Science Club. We invited students and Null Byte writers to deliver talks on Wi-Fi hacking, MITM attacks, and rogue devices like the USB Rubber Ducky.

When it comes to differentiating from the competition, brands are continuing to leverage augmented reality to give consumers to the point that there are few "firsts" left to achieve in the marketplace. While L'Oreal jumps on the augmented reality bandwagon for cosmetics, Acura finds a new way to make augmented reality a spectacle in the automotive industry.
Many developers, myself included, use Unity for 3D application development as well as making games. There are many that mistakenly believe Unity to be a game engine. And that, of course, is how it started. But we now live in a world where our applications have a new level of depth.
Who said sports need parity to be fun? For the third year in a row, the Cleveland Cavaliers are facing off against the Golden State Warriors on the NBA's biggest stage, and basketball fans everywhere couldn't be more excited.
Yes, there's a way for you to get translations of foreign language websites on your iPhone using the built-in Safari app. Problem is, it's not super obvious. Actually, you'd never know the option was there if someone didn't tell you. But with a little setup on your part, you can have Safari translate webpages whenever you need it to.
Cyanogen, Inc., the for-profit company that spun off from its CyanogenMod roots several years ago, has announced that they're shutting down all of their services. The company's impending demise shouldn't directly impact many Android users, but the announcement does have one major repercussion: The servers that used to host the popular CyanogenMod custom ROM have now been shut down.
In the first part of my containers series, we learned how to install Docker on our local machine, pull down "hello-world" and Ubuntu containers, SSH into containers, and install software when in a container. Now, we're going to work on building, customizing, and storing our refined hacking Ubuntu container. Before we dive right in, though, let's make sure we still have a functional Docker installation.
Unity released the Beta 5.6 on December 13 with a bunch of new upgrades in the works, including support for Vulkan, better instancing options, and more improvements to particles—to name just a few that are potentially relevant to the mixed reality community. And today, December 15, Unity has just released the EditorVR that we reported on a few weeks ago as a part of their "Experimental" builds.
Windows Insiders running Build 14971 of Windows 10 in the Fast Ring can now look for the "Windows Holographic First Run" app to check to see if their PCs are up to the task of running Windows Holographic. It won't detect your VR headset yet, but at least you'll be able to see if your computer will be compatible.
With all of the bare-bones setup out of the way in our Mac for Hackers series, your Apple machine should be ready to run a significant amount of pentesting tools. We can pull tools from GitHub and compile them, we can pull dependencies or tools from Homebrew, we have both Python and Ruby. Everything is ready to go and now it's time to start building a toolbox on our local host.
Reading through various internet forums, it certainly sounds like the Google Pixel and Pixel XL are attracting more iPhone users than any of Google's previous Nexus devices. The sales figures seem to back that up, too, as the Pixel is outpacing last year's Nexus 6P, and pre-order demand has exceeded Google's expectations, causing delays in shipments. (We reached out to Google but they wouldn't give us any specifics on sales numbers or numbers of switchers.)
Today at the Unite '16 conference in Los Angeles, Unity's Timoni West and Amir Ebrahimi showed off its new virtual reality authoring and world editor, EditorVR, using the HTC Vive. Coming in December to Unity is a version of its editor that works inside a VR headset, which will change the way developers interact with the worlds they build—even if they aren't building for VR.
If the recent "state sponsored" Yahoo hack wasn't enough motivation for users to stop using their services, the latest news about Yahoo should be. Joseph Menn, a reporter at Reuters, just revealed that Yahoo created a custom email wiretap service for the US government.
Whether you use Google Calendar, Exchange, iCloud, or any other service, you need a good Android calendar app to keep you organized on the go. For many folks, the obvious answer was always Sunrise Calendar, but Microsoft purchased the company behind this awesome app in a classic acqui-hire move, and now, Sunrise has officially been shut down.
If you find yourself switching between Android devices frequently—for instance, your Nexus 6P and a Samsung tablet—you've probably noticed how the button placement can be different. Normally, it's back, then home, then the recent apps button, from left to right. But Samsung devices have this backwards, which can lead to frustration when muscle memory kicks in and the back button isn't where you expect it to be.
The Nexus 5X and Nexus 6P have identical camera hardware—in fact, both use one of the highest-end camera sensors ever put into a smartphone. The only real difference between the cameras on Google's latest flagship devices is that the 6P natively supports electronic image stabilization (EIS) whereas the 5X does not.
