After a long hiatus, we shall once again emerge from the shadowy depths of the internet to build an exploit. This time, we'll be looking at how to defeat a non-executable stack by using the ret2libc technique — a lean, mean, and brilliant way of exploiting a stack overflow vulnerability.
The holidays are stressful. Between traveling, family, and dinner, Thanksgiving weekend can feel like weeks. Many families have traditions that make the days long, but some of us would rather curl up somewhere and watch our favorite shows.

Snapchat and its augmented reality capabilities have become a haven for music artists seeking to promote their new albums or simply amplify their art with immersive experiences.
The original iPhone SE was, for some, the perfect iPhone. It brought back the popular one-handed form factor of the iPhone 5 but packed in the internals of the then-new iPhone 6S. Now, the second-generation iPhone SE is here for 2020, but can it live up to what made the first-generation iPhone SE so popular?

As it turns out, we don't need to wait for an official announcement to get an idea of what new features and changes are coming to iPhone this year.
Silence spreads over these mountains like nothing I've ever felt. If I didn't have Moby blasting in my earphones, there'd probably be no other sounds around. Well, except for someone, Phil probably, murmuring in a nearby tent just low enough to make his words indiscernible.
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.
The private automobile has been an intrinsic part of our lives for around a hundred years. But over the last decade, car sharing has gained a very small but growing part of the mobility market. The more recent rise of companies like Uber and Lyft is witness to a more dramatic shift in mobility and car ownership. Private vehicle ownership to a transportation-as-a-service model has already started, and high capability SAE Level 4 vehicles will complete this trend.
Many lazy cooks skip rinsing off their grains before they cook 'em, but that's a big mistake for a few reasons. Some grains have coatings on them that need to be rinsed off to cook properly and taste good.

Google's new Material You theming engine in Android 12 adds a personal touch to your user interface. The main colors of your wallpaper dynamically affect the colors in menus and apps, essentially putting you in control of the overall theme. But there's another new design element for app icons that's hiding in your settings.
The year 2020 was a pivotal span of time during which the word "virtual" took on a brand new meaning. Instead of referring to VR or augmented reality, the term was hijacked to describe meeting across long distances through a variety of software tools, most often through video.
The Wallet app on your iPhone can be used to store and access event tickets, loyalty cards, boarding passes, gym memberships, airline miles, gift cards, coupons, and more — all in one centralized place. Before doing so, though, you must add your passes to Wallet, and there is more than one way to do it. However, not every pass can be added using all of the available methods.
The latest culinary trend? How about breaded and fried deer balls. That's right, you heard me. The Atlantic makes an interesting point about the political correctness of "nose-to-tail" eating:
Rob Scott shows how to stop weeds using sheet mulch in which a sheet of fiber membrane is placed over the soil. Subtitles and numbered steps make this video easy to follow. Stop weeds using sheet mulch.
Follow Monty's step-by-step video guide to laying an alpine garden path and making alpine beds using membrane and gravel.
Experimental house, "Roll It", is a collaborative project within Germany's University of Karlsruhe. The basic concept is as follows: using a cylindrical design to maximize space within a minimum housing unit. Not sure how "space efficient" this would actually be, but using it as transport could be fun (until the nausea inevitably sets in).
In this video tutorial, Creative Cow leader Michael Park shows you how to create a realistic 3d earth, complete with clouds and atmosphere, using only After Effects' built in effects. Special attention will be given to combining multiple instances of the CC Sphere effect to create unique layers with different specular properties for the land and water masses, as well as creating lights from urban centers on the night side of the earth.
Umbra, penumbra. Not exactly abracadabra, but if you've taken an astronomy class, you know exactly what the umbra and penumbra are. And any Earthling would agree that the umbra is the best place to be during a solar or lunar eclipse.

So, I got this email today from Groupon claiming today is Earth's 400 birthday. Groupon is known for their humor, but how (and why) did they pick today as Earth's 400th birthday?
To prevent bed bugs from entering your suitcase, you will need to pre-treat it, with diatomaceous earth. Bed bugs often hitchhike home with you when you stay overnight in hotels or on long trips. They will normally stow away in your suitcase. To prevent that from happening, dust your suitcase with a diatomaceous earth (DE) compound. For this, you will need a paintbrush, diatomaceous earth, and a large plastic bag. Sprinkle a little onto your suitcase, and use a dry paintbrush to spread the di...
Those of you who are proud to be Libras, well, you may no longer be Libras. You could be Virgos. At least, according to astronomer Parke Kunkle.
Seeing an aurora in person is one of the most amazing spectacles you could witness in the skies above. But what about the skies below?
I took this photo in Iceland at Snæfellsjökull, a 700,000 year old stratovolcano with a glacier covering its summit. The famous spot provides the setting for Jules Vernes' fictional A Journey to the Center of the Earth, in which the characters find a passage leading to the center of the earth. Standing up there was truly surreal—the strong winds whipped the snow, clouds and land all together into one incredible landscape.
Measuring the distance from the Earth to the moon doesn't require NASA equipment. The ancient Greeks did it, which means 2,000 years later, you can do it, too.
Mother Earth, God, Buddha, the Universe, energy fields... whatever you call it, lightning slo-mo'ed looks like some higher being set off some major fireworks. Beautiful. Two videos in the gallery below.
