How To: The Trick to Taking Perfect Selfies with Your iPhone

Unless you have a newer iPhone 6S or 6S Plus, the front-facing "FaceTime" camera on your iPhone has a pretty weak, low-res sensor, which means unflattering selfies. You could use the rear "iSight" camera to take a high-res selfie, but framing your mug properly and hitting the shutter is difficult, takes many failed attempts, and usually results in a lackluster photo.

How To: Check Your Heart Rate on Any Android Phone

Samsung created quite a buzz when it debuted a built-in heart rate sensor on the Galaxy S5 back in 2014, but amazingly, not many other manufacturers decided to follow suit. It's really a shame, too, since data from a heart rate sensor would go perfectly hand in hand with the increasing fitness- and activity-tracking features that most smartphones sport these days.

Android Basics: How to Connect to a Wi-Fi Network

If you're just starting out with Android—or smartphones in general, for that matter—there are a lot of little things to learn. One of the first terms you'll likely encounter is "Wi-Fi," which is a wireless internet connection served up by a router in your home, office, or local coffee shop. This differs from your smartphone's regular "Mobile Data" connection, which is provided by your cellular carrier and included as part of your monthly bill.

Basics of Ruby: Part 1 (Data Types/Data Storage)

Ruby is a dynamic, general-purpose programming language created by Yukihiro "Matz" Matsumoto in Japan around the mid-90's. It has many uses but with it's flexibility, it makes a great language to write exploits in. In fact, the entire Metasploit Framework is written in Ruby! The sole purpose of this series is to teach hackers the basics of Ruby, along with some more advanced concepts that are important in hacking.

How To: Bypass T-Mobile's Tethering Limit for Free

T-Mobile's "Uncarrier" initiative has done wonders for my wallet and my data usage. Before I had to deal with being throttled down to 2G speeds after passing my data limit, but thanks to their unlimited data plans, I'm free to use as much LTE data as I possibly can. The only downside is, when sharing data through a mobile hotspot (tethering), T-Mobile imposes a 5 GB limit (which was recently upped to 7 GB for some).

How To: Download & Save Any File Type onto Your iPhone

On an Android device, you can download almost any file type into a neat and tidy "Downloads" folder, and those files can then be accessed with an appropriate app, shared via email, or transferred over to your computer. On an iPhone, there is no such folder, and saving files from Safari is almost impossible unless you're jailbroken.

How To: Bypass Location Restrictions to Use Any Snapchat Geofilter You Want on Android

In 2014, Snapchat introduced a special type of Filter called Geofilters. Geofilters only appear when you're in a specific location. For example, a Disney Land Geofilter will only appear if you're actually there. Rather, your phone needs to think that you're at Disney Land. By spoofing your GPS location, you can effectively travel all across the globe — at least in the eyes of Snapchat.

How To: Permanently Browse in Desktop Mode on Android

The majority of Android web browsers carry a "desktop mode" feature that makes mobile websites look like normal computer versions. Mobile versions are designed to work faster and more efficiently on smartphones, but sometimes the desktop version looks better on large displays or has additional features not included in the mobile one.

How To: Theme the Quick Settings Icons on Your LG G3

While the Quick Settings feature on Android is great, manufacturers like HTC, LG, and Samsung took it a step further in their custom skins. For instance, on Samsung devices, you can access the most common toggles at the top of the Notification tray, and you can tap once to access more tiles. This makes toggling cellular data, Bluetooth, and Wi-Fi a fast and painless process.

News: Is FireChat the Future of the Internet?

As you already know, Hong Hong has been rocked in recent weeks by protests against their Beijing overlords. Promised free and fair elections, Beijing has reneged on this promise and is now telling Hong Kongians (that's what they're called, aren't they?) that they will only be able to vote on Beijing-selected candidates. All that is interesting from a political perspective, but from a technological perspective, the more intriguing story is how the protesters are communicating. Faced with their...
