If you've got a birthday party to plan for a young budding scientist coming up, a little nitrogen should do the trick. In this project, I'll show you 10 "super cool" tricks with liquid nitrogen that you could try, but probably shouldn't!
If you're going to build yourself a water gun to cool down this summer, or maybe just a useful water pump, you'll need some check valves. However, the most expensive parts of a water pump or DIY super soaker are usually the check valves. So, let's make some from scratch for as little as $0.35 each.
Apple is set to release its latest operating system for iPad, iPhone, and iPod touch this fall, and if you haven't noticed yet from our iOS 7 softModder guides, it's going to be pretty slick.
In Minecraft, a large aspect of the game is PVP (Player vs. Player Combat). A hardcore Minecraft fan will remember that back in Beta 1.8, combat was switched up, and it really changed the game around. Here are some tips on what a two-year Minecraft player has to say.
Lurking inside your old junk microwave is an abundance of useful parts that can let you melt metal, spot weld, and make electrifying Jacob's ladders. You can even make a powerful AC arc welder, perfect for making hard-to-solve puzzles and even makeshift weapons for the zombie apocalypse.
UPDATE (February 26, 2014) Yesterday, the U.S. House of Representatives passed H.R. 1123 with a 295-114 vote decision. The ruling repeals the 2012 Library of Congress (LOC) decision that limited the ability to legally "unlock" your smartphone (see below).
Sherlock Holmes is one of the most famous characters in modern history, and has appeared in film more often than any other character. No less than 78 different actors have taken their turn at portraying the enigmatic deduction machine in various mediums, and each has brought their own foibles to the role. Some of the names may even surprise you: Tom Baker, John Cleese, Peter Cushing, Charlton Heston, Christopher Lee, Roger Moore, and even Leonard Nimoy.
The vast majority of people involved in Steampunk are interested in history but, like with science, there's something about history that we don't talk about very often: The holes.
With the new year right around the corner, it's time to talk about the end of the 19th century, a time which plays an enormous role in Steampunk. If you've done any reading of British books written from about 1890 to 1899, you may have come across the phrase 'fin de siecle' and wondered what it meant. You also may have come across this term in reading about the late Victorian era. No worries, I'll tell you all about it! Image by Giovanni Dicandia
An internet connection has become a basic necessity in our modern lives. Wireless hotspots (commonly known as Wi-Fi) can be found everywhere!
OSAGYEFO DR. KWAME NKRUMAH (1909-72) Founder and Father of the Nation Osagyefo Dr. Kwame Nkrumah, the first Prime Minister and President of Ghana, stands out not only among the Big Six but also among the greatest statesmen of history. It was he who canalized the discontent of the people of the Gold Coast Colony into the highly organized movement of protest against British rule, and within a relatively short period won political independence for Ghana on March 6, 1957. With Ghana independent, ...
Safari keeps getting better and better on the iPhone, and that's exactly what happened with the latest Safari 16 update for iOS.
While Apple's reputation for privacy and security is nearly unmatched, it'll never be perfect when Hey Siri is always listening. Aside from iOS devices, Hey Siri always listens for questions and commands on the HomePod and HomePod mini smart speakers. If you rarely use Hey Siri on those speakers, it's worth disabling the feature for some extra privacy.
While Apple has been rather secretive about its work on AR wearables (despite the abundance of leaks revealing details about their unannounced devices), Facebook has been rather chatty about its plans for smartglasses.
Quietly, while the rest of the world was engaged in pandemic and political concerns, a few weeks ago Facebook casually upgraded its Spark AR platform with what it calls Unified Effect Publishing.
Google's Pixel smartphones have earned a reputation for taking great photos without relying on top-of-the-line camera sensors. Instead, Google leans on the software side to squeeze super images out of its camera. This also enables them to roll out new features out to previous-generation devices.
Android has not had the best reputation for privacy and security, though Google has made strides in those departments in recent years.
It's safe to say that we can call the annual ranking of AR investments a holiday tradition at Next Reality.
Whether it's a short road trip or an 18-hour flight, our phones are now essential travel companions. No longer do we need a GPS unit, maps, cameras, camcorders, or even boarding passes. However, not all phones are created equal in this regard. Some are more suited for traveling, no matter the duration.
I noticed the neon yellow sign at the new location of Pho Bar in Chinatown right away. The sweeping cursive yellow letters spell out "Crazy Rich Broth"; the same phrase printed on the back of servers' shirts. It's the kind of minimalist but colorful design feature that is especially popular on Instagram at the moment — shots of patrons in front of a glowing sign.
There's a lot of misinformation about VPN services, and it stems from the fact that not all of them are created equal. Some focus on privacy, others on security, and a few VPNs are seemingly even purpose-built for the polar opposite: data collection. We made this guide to help clear the air on some of these issues while objectively ranking the best of the best.
Apple's macOS operating system is just as vulnerable to attacks as any Windows 10 computer or Android smartphone. Hacker's can embed backdoors, evade antivirus with simple commands, and utilize USB flash drives to completely compromise a MacBook. In this always-updated guide, we'll outline dozens of macOS-specific attacks penetration testers should know about.
One could argue that, at least for the moment, software development is more important to the augmented reality experience than hardware. Since a viable augmented reality headset has yet to emerge for the broader, mainstream consumer market, currently, the same devices that make texting and selfies possible are leading the charge to enable easy-to-use AR experiences.
Windows 10 and macOS have poor reputations when it comes to customer privacy and user policies. Our hacking Windows 10 and hacking macOS articles might make it seem like a reasonably secure operating system doesn't exist. But I'm here to tell you that there is a viable alternative that could provide some sense of security and trust.
A powered-off Windows 10 laptop can be compromised in less than three minutes. With just a few keystrokes, it's possible for a hacker to remove all antivirus software, create a backdoor, and capture webcam images and passwords, among other highly sensitive personal data.
Virtual private networks, or VPNs, are popular for helping you stay anonymous online by changing your IP address, encrypting traffic, and hiding your location. However, common IoT devices, media players, and smart TVs are hard to connect to a VPN, but we have a solution: Turn a Raspberry Pi into a router running through PIA VPN, which will ensure every connected device gets the VPN treatment.
The dark web is an intimidating place for a newbie hacker, but it's a powerful tool once you've learned to navigate it safely. To help you out with that, this guide will cover some need-to-know information for traversing the dark corners of the internet while keeping your identity and data safe. (Hint: Using Tor is not enough.)
Privacy and security go hand in hand, especially for smartphones. When it comes to privacy, you decide what personal information about yourself is out there to discover. Security, on the other hand, is all about enforcing those privacy decisions.
Lack of appetite often signals a cold or flu. Eating can be the last thing we want to do when we have a sore throat or are too fatigued or achy to even get out of bed. When hungry, we don't feel as strong as when we are well fed—and we more than likely aren't as strong.
The year was 1947. Scientists had isolated a virus from a pyrexial rhesus monkey in Uganda and named it after the forest where the monkey lived — Zika.
Ready to try and sew-in your own weave? It's a big decision. As with everything that concerns our hair, we struggle with the pros and cons and often dwell on what could go wrong. Pixie cut. Perm or not? New shade (of pink, purple, or blue). These are all major decisions because ... well, it's our hair, and hair is such a big part of our style. To get a weave or not calls for careful consideration, and to sew one in yourself, that's an even bigger internal debate.
The experience of actually using the HoloLens 2 can be difficult to describe to anyone who hasn't had a chance to directly interact with the device in person and be blown away by its immersive capabilities.
Apparently, we learned nothing from Jurassic Park, as scientists are still working on bringing extinct species back to life. Until that day comes, you can interact with long-lost animals through augmented reality...if you have a newer model iPhone.
Web browser extensions are one of the simplest ways to get starting using open-source intelligence tools because they're cross-platform. So anyone using Chrome on Linux, macOS, and Windows can use them all the same. The same goes for Firefox. One desktop browser add-on, in particular, makes OSINT as easy as right-clicking to search for hashes, email addresses, and URLs.
With protests springing up across America, there's a chance you may have your first interaction with law enforcement. Many demonstrators will have their phones in-hand to film the action, which, sadly, could prompt an officer to demand the device and any self-incriminating data it may contain. Before this happens, you should know there are tools at your disposal to protect your data in such situations.
We all want to be healthy, but in practice, it can be tricky, especially from the fitness angle. Our lives seem busier and busier, which makes hitting the gym quite the challenge. What if we told you there was a real way to work on your fitness in the comfort of your own home — in just seven minutes a day? All you need is a chair, a wall, and a 7-minute workout app.
So you want to know what that person who is always on their phone is up to? If you're on the same Wi-Fi network, it's as simple as opening Wireshark and configuring a few settings. We'll use the tool to decrypt WPA2 network traffic so we can spy on which applications a phone is running in real time.
Starting Sept. 13, you can preorder the iPhone 11, 11 Pro, or 11 Pro Max from Apple, wireless carriers, and various e-commerce websites. However, unlike with Android smartphones, there is only one set of iOS phones that come out each year, so they're pretty hot items. That means being the first to get your hands on one could be a challenge, but we're here to help you out.
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.
The worlds of augmented reality and virtual reality are closely linked in many ways. That means it's smart for AR insiders to keep a close on new developments in VR. If you have been paying attention, you know that Oculus CTO John Carmack is one one of the most important thinkers in the VR space.
