A new tidbit of information hints at an addition to the company's unfolding story that almost no one had accounted for: retail stores.
Welcome back, my tenderfoot hackers! Those of you who have been reading my posts here for awhile know how much I emphasize good reconnaissance. Novice hackers often jump into a hack/exploit without doing proper recon and either fail or get caught. Experienced and expert hackers know that 70-80 percent of a good and successful hack is dependent upon successful and accurate reconnaissance.
For hire! Netflix is looking for someone who loves to watch movies and TV shows in the comfort of their own home for hours on end. Does this sound like what you do on your free time? Then you might want to update your résumé, because this job opening is real.
In this "Quick Clip," I tried dunking inflated balloons into a container filled with liquid nitrogen until they were completely flattened and seemingly destroyed. Once out of the liquid nitrogen, the balloons come back to life and reinflate on their own—without even touching them!
There's no shortage of techniques when it comes to light painting—you can use LEDs, flashlights, or even make your own light painting nunchuks. If you want to do something a little different, though, why not use a projector like photographer Brian Maffit did to capture these gorgeous long-exposure shots of a recent snow storm? Maffitt used a projector to play the movie The Lorax onto a tree in his backyard, providing the backdrop for these photos. The long exposure shots were taken using an o...
This goes out to all of the Tweeters out there looking to get a little more creative with their Twitter accounts. My page has always been extremely basic, because I just never bothered to pretty it up. I just had one of the stock backgrounds and the good ole Sacramento Kings logo for my profile pic. So, if you want to add your own cool photos and backgrounds to your account, the folks over at Twitter made this funny cartoon video just for you. It's not the most complicated of tasks, and every...
This is a cool little trap that me and some friends came up with while messing around with TNT and redstone on a big platform in the sky. The reason we called it the 'Roof Lever Trap' is because it utilizes the ability to place levers on the bottom side of blocks, which was introduced in Minecraft 1.3.1.

In this outdoors how-to video from fitclimb.com we're shown how to make a fire in the snow. The first step is to find a good flat spot, or make a flat spot yourself. Next, we look for trees with dead branches and break those dead branches off for the wood. The key here is to be organized because you'll have to carry this wood back to your camp. Next, you want to make a platform for your fire to keep it from sinking down as the snow melts. Here, we're using the bark from a dead stump for a pla...
Find Osman in the Cathedral Square to deliver Alexander's message to him in Mission 5 on the Sony PSP. Make your way to the Cathedral area, at which point the red delivery icon pops up and denotes Osman's rendezvous point. The only problem is that the area is swarming with guards and that Altair must make successful contact without being detected. Climb up the first buildings in front of you and hop across toward the icon. Silently dispatch the archer on the roof and then head around to the o...

The worldwide health crisis around the coronavirus has gripped the live events industry, particularly in the tech sector, with the cancellations of Mobile World Congress, the Game Developers Conference, Facebook's F8, Google I/O and now South by Southwest.
Cross-site scripting can be one of the easiest vulnerabilities to discover, but to be successful with this type of attack, it is essential to learn how to get past filters. In the previous guide, we explored some ways to do this, such as abusing attributes and event handlers and tricking the application into accepting unusual characters. Now, let's take a look at more techniques used to defeat filters.
It is often said that the best hackers remain unknown, and the greatest attacks are left undiscovered, but it's hard for an up-and-coming penetration tester or white hat to learn anything unless one of those factors is actually known or discovered. But the end goal here in our SQL injection lessons is to make that statement as true as possible for us when performing our hacks.
Until self-driving cars become mainstream, augmented reality might be the next big technology to hit your dashboard.
Generally speaking, in terms of modern devices, the more simple you make an interface to navigate, the more successful the product is.
A recently confirmed polio outbreak in Syria is connected to low levels of vaccination, worsened by conflict. It is the first confirmed incidence of polio in Syria since 2014. Before 2013, the last case of polio in Syria was in 1999.
Amazon's first venture into the wireless phone market was a crash and burn moment — and that's us being kind. Their FirePhone went down in flames almost instantly, no pun intended.
There's a new operating system on the horizon, and this one's so big that it may actually live up to its galactic moniker. Andromeda, a merging of Android and Chrome OS, has the potential to bring Google to the ubiquitous status that Microsoft's Windows enjoyed in the '80s and '90s.
The biggest problem with plastic wrap is also its most useful trait: its incredibly clingy nature. Plastic wrap seems to stick to itself or you before you can get it over the plate, bowl, or food you're trying to preserve. And once you do manage to get it in the right position, it never sticks as well as you need it to. Fortunately, you can combat these inconveniences with two extremely helpful methods—a change in temperature or a bit of added moisture—as Jenny Stewart of CHOW explains in the...
Yup, you read that right. As of now, you can actually play the first level of one of the most popular video games of all time—Super Mario 64—directly in your web browser.
Welcome back, my hacker novitiates! In an earlier tutorial, I had introduced you to two essential tools for cracking online passwords—Tamper Data and THC-Hydra. In that guide, I promised to follow up with another tutorial on how to use THC-Hydra against web forms, so here we go. Although you can use Tamper Data for this purpose, I want to introduce you to another tool that is built into Kali, Burp Suite.
Most of you already know that a zero-day exploit is an exploit that has not yet been revealed to the software vendor or the public. As a result, the vulnerability that enables the exploit hasn't been patched. This means that someone with a zero-day exploit can hack into any system that has that particular configuration or software, giving them free reign to steal information, identities, credit card info, and spy on victims.
Auto-correction is a double-edged sword if I ever saw one. It's great because I'd have an abundance of typos without it, yet it's extremely frustrating (and embarrassing) when it doesn't actually work. Just take a look at the very recent example below from Breaking Bad star Aaron Paul. Funny for us, embarrassing for him. I have a particularly difficult time typing on small keyboards (i.e. fat-finger syndrome), so disabling auto-correction on my Samsung Galaxy S4 is a no-go. I'm willing to ris...
In a world where mobile devices are the new norm for interacting and staying in contact with one another, it's important to make the experience as smooth as possible, and typing is the biggest problem for me.
You've got to be sick of it by now. Those meaningless and unsatisfying articles, lists, and videos you were duped into clicking on because their headline made them impossible to resist.
Recently, I offered a guide detailing how to run two separate windows on a Nexus 7 tablets for better multitasking. While extremely useful, that mod was limited to only two windows, and you also needed root access to use it.
For those of you who have (or had) and iPhone, one of the cooler photo apps for iOS was VSCO Cam, an extremely popular camera with pro-quality filters and effects. Now this app is available for Android on Google Play for your Nexus 7 tablet and any other devices running Android 4.0 and up.
There are a gazillion lock screen apps available on Google Play, but the majority of them are subpar and not worth your time. However, in my opinion, there is definitely one out there worth your time—one that constantly learns and adapts to what apps you use when and where to determine which shortcuts to give you.
Welcome back, my hacker wannabees! Most of my recent posts have addressed using Metasploit’s Meterpreter and what we can do once we have embedded it on the victim’s system. This includes remotely installing a keylogger, enabling the webcam, enabling the microphone and recording, disabling the antivirus software, among many other things. The list is almost unlimited.
Text adventure games, such as the well-known Zork series, were some of the first computer games ever made, second only to the likes of Spacewar! and the better-known Pong. So let's travel back in time for a moment, to a time that never was.
You know how sometimes you accidentally send a minecart shooting out down your tracks, and you can only watch helplessly as it fades into the distance? And then you know that you have to go find it and break it, so that it doesn't stop up your cart traffic on your tracks.
There are a lot of programs which allow opening archives. Alas, most of them are rather complicated to use. The process of the archive opening often takes much time. Hopefully, there are some programs which are simpler to use for regular users.
You've manage to get your hands on some ruthenium, and now you want to destroy the hard silvery-white metal of the transition series. Well, you're going to try all kinds of ways to dissolve this odd metal, but the only successful way to dissolve ruthenium is with a common household cleaner… bleach.
