How To: Writing 64-Bit Shellcode - Part 2 (Removing Null-Bytes)

Welcome to the sequel to the latest post on writing 64 bit shellcode! This tutorial will assume that you are aware of everything mentioned in the last one, as I will try to make this tutorial void of formalities and straight to the point! If you have not read the last one, I suggest doing so unless you are familiar with basic assembly programming and system calls. This is by no means rocket science, so therefore I will simply repeat my TL;DR from last time before we get started, so that the a...

How To: Make Garlic-Infused Olive Oil & Vinegar at Home

Garlic—it stinks so good! It's one of nature's most wondrous foods, being both delicious and incredibly healthy. What's not to love? Well, it is kind of a pain to prep, whether you're peeling a couple of cloves for a sauce or a whole head and trying to mince it finely. One way to get around the whole peeling and mincing issue every time you want garlic in a dish is by buying pre-made garlic-infused olive oil, except that stuff is pretty pricey. Learn to make it at home and you'll get all the ...

How To: Understanding Signature Schemes: How Data Sources Are Authenticated, Secured, & Spoofed

One of the biggest problems in data security is authentication of data and its source. How can Alice be certain that the executable in her inbox is from the venerable Bob, and not from the not-so-venerable Oscar? Clearly Alice wants to know because if this file is actually sent to her by Oscar, the file might not be a game, but a trojan that can do anything on her computer such as sift through her email and passwords, upload her honeymoon pictures, or even turn on microphones and webcams. Thi...

How to "Eat" Your Sunscreen: 10 Nutrient-Rich Foods That Will Increase Your Sun Tolerance

Even as someone with super pale skin that burns instead of tanning, I don't use sunscreen nearly as often as I should. Or, uh...ever. My skin cancer prevention routine mostly involves hiding from the sun as much as humanly possible. If you're like me and hate the greasy feeling of sunscreen, there are other ways you can protect your skin by increasing your sun tolerance. Your diet actually has a lot to do with how easily you burn, so by getting enough of a few key nutrients, you can decrease ...

The Time Traveler's Companion: Surviving the Past and Future with Your Kindle

Not that long ago I wrote an article discussing what it would be like, realistically, if you were to accidentally travel back in time to the Victorian era. At the end of that article, I mentioned that the best thing you could bring with you on a time-traveling adventure is a Kindle, or similar e-reader, stuffed full of the knowledge of the 21st century. Why a Kindle? Well, I own a Kindle, and I love it. However, there's far more to it than that.

How To: What You Need to Know Before Voting on Facebook's Proposed Policy Changes This Week

A few weeks ago, Facebook published a blog post called "Proposed Updates to our Governing Documents," which outlines a few changes in their policies and user voting system. These changes would essentially take away users' right to vote on future changes to Facebook's data use policy while also taking away Facebook's responsibility to alert users of those changes. If the new policy is enacted, the vote will be replaced with "a system that leads to more meaningful feedback and engagement," what...

News: 8 Tips and Tricks Every Steampunk Writer Should Know

While I am a writer with a degree in Creative Writing, I haven't published any Steampunk fiction. However, as a panelist and track director, I've been on panels with many well-known Steampunk writers and have gleaned insight from the things they've said. I've compiled some of those things into this post, which will hopefully be helpful to all of the writers out there!

Hacker Fundamentals: A Tale of Two Standards

If you read my article on the OSI model, you got a good overview on communications from that model's perspective, but how does that relate to TCP/IP? We're going to take it a step further, getting into the idea behind the two address concept. How does an IP address and a MAC address work together? If you want to hijack sessions and all sorts of lulz like that, you need to understand these concepts. Let's get into it, mates!

News: This Is Why All Augmented Reality Startups Suck

People fundamentally distrust magicians. And they should. The illusions they proffer are just that, illusions meant to astound rather than tangible interactions and results that have weight and meaning in our real world. Our lizard brains know this, and, no matter what the outstanding feat of "magic" presented, we nevertheless hold fast to our survival-based grip on the truth: we just saw simply "can't be real."

News: 15 Remote Assistance Apps Driving the Enterprise Sector of Augmented Reality, from HoloLens to iPhone

Comparing the present-day states of the consumer and enterprise sectors of augmented reality is like evaluating the merits of sports car versus work trucks. Like consumer AR, sports cars are sexy and exciting, but perhaps a bit impractical at times. On the other hand, enterprise AR is utilitarian, but it gets the job done and, in the long run, pays for itself.

NR30: The Mobile AR Leaders of 2018

This time last year, we got our first taste of what mobile app developers could do in augmented reality with Apple's ARKit. Most people had never heard of Animojis. Google's AR platform was still Tango. Snapchat introduced its World Lens AR experiences. Most mobile AR experiences existing in the wild were marker-based offerings from the likes of Blippar and Zappar or generic Pokémon GO knock-offs.

News: 5 Major Problems Magic Leap One Faces on Day One

The mysterious technology product teased via an eccentric TED Talk nearly five years ago has finally been revealed, and it's called the Magic Leap One: Creator Edition. After all of the non-disclosure agreements, furtive comments from CEOs and insiders given early access to the device, and a seemingly never-ending string of hints dropped by the company's CEO, Rony Abovitz, on Twitter, we finally have a real look at the product.

How To: Update Your iPhone's Lock Screen with an Attention-Grabbing Note, Reminder, Warning, or Other Custom Message

There's a lot you can customize on your iPhone's Lock Screen — wallpapers and photos, widgets, the display mode, notifications, and even the time's font and color. But there's another feature that lets you add custom text for whatever you want, whether it's an inspiring quote, a reminder, a warning to anyone who dares touch your iPhone, or even just your name.
