If you're considering purchasing Apple's new 2020 iPhone SE, which brings many modern components into the compact body of an iPhone 8, you should know what its dust and water resistance rating means. Just how dirty and wet can the iPhone SE get without breaking any functionality?
As the calendar year (and, for many companies, the fiscal year) comes to a close, it appears 2017 may stand as the new high-water mark for investment in augmented and virtual reality technology.
As many of you know, I firmly believe that hacking is THE skill of the future. Although the term "hacking" often conjures up the image of a pimple-faced script kiddie in their mother's basement transfixed by a computer screen, the modern image of the hacker in 2015 is that of a professional in a modern, well-lit office, hacking and attempting to development exploits for national security purposes. As the world becomes more and more digitally-dependent and controlled, those that can find their...
Hydrazine sulfate has many uses, but most notably, it's been used under the trade name of Sehydrin, a treatment for anorexia, cachexia and some even think cancer. But for we DIY chemists, it's useful for something entirely different— as a substitute for the more dangerous pure liquid hydrazine in chemical reactions. NurdRage shows you how to make it via some hypochlorite and the Ketazine process.
Chlorine gas is a very useful oxidant, which was first introduced as a toxic weapon by the German Army. Even today, it's still used as a weapon, most recently in the Iraq War by insurgents. But chlorine gas has more useful (and less lethal) applications, and if you want to learn how to make some at home, NurdRage has the answers.

If you've rooted your phone (good for you!) and for some reason want to go back to the stock configuration that your phone was in when you took it out of the box, this video will show you how to do it. One good reason is if you want to update your phone's firmware, which will not work if you phone is rooted ...

It might seem like an inconvenience but it is important to take the time to find out what has caused your oil light to come one in your car. You may just be low on oil or you may have a more serious problem but ignoring the warning will only lead to further damage.
This is a common embellishment for back ochos and takes a little practice to work up the speed to do it but once you do you'll find lots of places to fit it in. During back ochos, beat your free foot in front as it passes the other on the "&" count (halfway through the beat), before stepping behind into the next step. (You should feel the achilles tendon at the back of the free leg hit the lower part of the shin of the standing leg, just above the ankle.) Try not to let your legs turn-out as ...
The words of three of tech's most important executives in the last 48 hours are providing some valuable insight into the near term future of augmented reality and the cloud infrastructures that support it.

If you want to root your phone, it's a huge plus. If you want to install a custom ROM like LineageOS, it's an absolute must-have. Custom kernels like ElementalX, custom recoveries like TWRP — none of this happens unless you buy a phone with an unlockable bootloader.
With the announcement of Google Glass Enterprise Edition last week, a literal behemoth entered the arena of companies serving augmented reality solutions to business customers. While Google Glass, with the backing of Alphabet, has the potential to be a disruptor, the field already has a number of players who have been in the game.

Returning your device to stock, whether it is because you need to sell it or just want to receive OTAs again, is not always a simple process. Since HTC has released countless variations of both the M7 and M8 HTC One, it can be a pain in the ass finding the right files and tools to get your phone back to stock settings.
I hate flying for two reasons. Firstly, I'm afraid of heights and turbulence is absolutely hellish. Secondly, I hate overspending on airfare. Flying can be unnecessarily expensive, especially if you don't plan ahead or must deal with inclement weather. Nevertheless, the travel season is almost here and we're always looking for the cheapest, most convenient flight. But what service actually provides you with exactly that?

Prior to the release of Android 4.0, most devices had a dedicated search button. This functionality allowed you to search Google from your home screen and app-specific content from within any app. Eventually, though, this dedicated search button was ditched in favor of an icon in the action bar of apps, and a search bar on the home screen.
The international hit Xperia Z2 may be headed to Verizon if a posted, and quickly erased, image is any indication. Take this information with a grain of salt—I certainly am—but this could be Sony's entrance into the non-GSM realm. The image above was posted to Sony's Xperia Google+ page, and very quickly removed. Compared to the Z2 that's currently on the international market (below), we can see that not only has the Sony logo shifted to the bottom, but a Verizon logo rests squarely along the...
