One of the basics of electronics is knowing how an electrical current works. For this video, you will need a 1.2V battery, a lightbulb, and 2 copper wires. First, take the wires and attach one end of each wire to opposite sides of the battery. Have a friend hold the wires there, or tape the wires down. Then, take the unattached ends of the wires. Take one wire and touch it to the upper part of the base of the lightbulb. Take the other wire, and touch it to the bottom. The lightbulb should now...
In this lesson we will learn about one of the most important concepts in algebra SQUARE ROOTS. The square root of a number m is another number n that satisfies the following formula: m = n x n. You can also say that m is the square of n. The opposite of squaring a number is finding its square root. You can use the radical symbol to indicate that the square root of m is n:

Okay, so obviously this stew has a bit of an ick factor. Because when we say "oxtail," we MEAN oxtail. While the thought of eating a tail probably doesn't sound palatable, oxtail is actually quite a nice - if different - cut of meat the inquisitive gastronome should try.
There's a tool on your iPhone that can help you with your overall emotional well-being, one that can help you be more aware of your emotions throughout the day and build resilience against the stressors in your life.
One of my favorite perks of this job is the opportunity to try out all the big flagship phones each year. Whether it's rating their suitability for a particular use-case or just entering their specs into our comparison tool, we have to get our hands on all major phones released in the US. We pride ourselves on being fair in our reviews and roundups, but that doesn't mean we don't have preferences.
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.
The $35 Raspberry Pi is an amazingly useful single-board computer (SBC) with a good balance of price, performance, and connectivity options. But for some projects, it just isn't enough.

An incorrectly scaled object in your HoloLens app can make or break your project, so it's important to get scaling in Unity down, such as working with uniform and non-uniform factors, before moving onto to other aspects of your app.
Over the years, the internet has become a dangerous place. As its popularity has increased, it has attracted more hackers looking to make a quick buck. However, as our dependency on the web grows, it becomes increasingly difficult to sever all ties. This means we have to protect one of our weakest points, the password.
When hacking Wi-Fi networks, having the right wireless adapter is essential. But hunting online for one can be a frustrating experience. To see how the handful of Kali-compatible adapters on the market measure up, I ran a series of tests to benchmark and compare their range, signal strength, and ability to enter monitor mode and perform packet injection. This should help you determine which adapter is right for your own hacking needs.
Social engineering makes headlines because human behavior is often the weakest link of even well-defended targets. Automated social engineering tools can help reclusive hackers touch these techniques, but the study of how to hack human interactions in person is often ignored. Today, we will examine how to use subtle, hard to detect persuasion techniques to compromise a human target.
Beginners luck is a phrase I have always hated. But really, beginners luck comes down to not letting your experience in something get in the way of the idea.

Many of your accounts online likely require two-factor authentication (2FA) or two-step verification (2SV) to confirm your identity when logging in, and there's a good chance the second factor or step for each is a one-time email or SMS verification code. If you get a lot of email and SMS codes, it can clutter your Mail and Messages apps with junk if you don't delete the messages after signing in.

And as good as that sounds, the fine print can complicate things real quick.
Nowadays, our phones are capable of just more than 30 fps video. Phones like the Galaxy S10 can shoot 4K at 60 fps, even on the front camera. Slow motion functionality has recently started to appear on more and more devices — but as you may have noticed, the quality of the feature differs from phone to phone.
The camera punch hole on the S10 has gotten our creative juices flowing more than any notch ever could. First, we saw wallpapers that served to camouflage the cutout or even accentuate it. Now, if you want to go the opposite direction and highlight your S10's camera hole, there's an app that turns it into a circular battery meter.
Among the younger generation, Roblox rivals major titles like Minecraft as one of the most popular online games out there.

The Pixel 3 XL versus Galaxy Note 9. Stock Android versus Samsung Experience. When I began this comparison, I thought the Pixel 3 XL would be unfairly outmatched.

If bezel-less was the goal of OEMs in 2017, 2018 seems to be the year of the notch. Thanks in no small part to Apple's iPhone X, more and more smartphone manufacturers are designing their displays with this polarizing cutout. While many are frustrated with the trend, it's worth taking the time to consider what each phone gains with the unique design.
Your email inbox is a treasure trove of personal data. The people you contact, your writing style, which messages you flag as spam — all of this information and more can be used to paint a clear picture of you.

While it may not be an obvious feature, Apple actually built a way into iOS that lets you hide specific pictures and videos in the Photos app that you want to keep on the down-low, for your eyes only.
