Hello everyone! How's subnetting going? Did you practice a lot? I hope you did, but even if you didn't we will go through some more examples so you can be feeling confident after reading this article. It's all about that bad boy binary!
Hello ladies and gentlemen, welcome back to the Part 2 of our UDP & Wireshark adventure as I promised. Last time we discussed about what DNS is and how it uses UDP as its transport protocol but we left some unexplained parts behind and I'm about to investigate those with you. I would advice you to go back to Part 1 so you can have a clear understanding in case you don't feel comfortable with the topic. So our computer made its request to the DNS server and asked "Hey, I want to find out what ...
As you might know, there are a multitude of tools used to discover internal IP addresses. Many of these tools use ARP, address resolution protocol, in order to find live internal hosts. If we could write a script using this protocol, we would be able to scan for hosts on a given network. This is where scapy and python come in, scapy has modules we can import into python, enabling us to construct some tools of our own, which is exactly what we'll be doing here.
Welcome back, my tenderfoot hackers! Have you ever wondered where the physical location of an IP address is? Maybe you want to know if that proxy server you are using is actually out of your local legal jurisdiction. Or, maybe you have the IP address of someone you are corresponding with and want to make certain they are where they say they are. Or, maybe you are a forensic investigator tracking down a suspect who wrote a threatening email or hacked someone's company.
The only mail I like getting comes in the form of an Amazon package, but when I go to my mailbox, it always ends up being a pile of credit card offers and catalogs I could never see myself ordering from. Those pieces of junk mail usually end up in the trash, which is horrible when you think about all the trees that had to get cut down in order to produce them.
Welcome back, my novice hackers! The worst thing that can happen to any hacker is being detected by a security admin, the security technologies (IDS, firewall, etc.), or a forensic investigator.
Welcome back, my greenhorn hackers! Recently, I asked the Null Byte community what subject they would most like me to cover in future tutorials. Many of you cited scripting, and I decided it's best to cover this subject soon, so here goes.
For people that live outside of the United States, how many times has this happened when surfing through U.S. streaming services? If you're outside of the U.S. market and want to stream stateside services like Hulu, MTV, CBS, Pandora, and others—you're in luck. Tunlr is an application that re-addresses certain data envelopes, tricking the receiver into thinking the data originated from within the U.S. by using its own DNS server's IP address. You can even watch some non-US shows stateside, li...
Lea Michele, like her overachieving character Rachel in "Glee," has a bit of a diva complex. But with that talent, those smashing pearly whites, beestung lips, and gorgeous dark brown hair, we don't blame her.
The first and most basic tenet of origami is creating shapes using a single piece of paper. However, when it comes to modular origami, which is complex and multi-sided, this rule becomes a little more lenient. It's actually rather common in modular origamit o see magic cubes or 36-sided stars being assembled from multiple pieces of paper.
You know how sometimes you'll look up a recipe from a famous chef, and then when you take a gander at the ingredients list it looks longer than the last "Harry Potter" book? Complex, "high art" dishes sometimes do requires what seems like a million ingredients - and precise stirring and heating times - to accomplish.
Like all famous artists, Frida Kahlo had a very colorful life. Raised in a small town outside Mexico City, she lived through the Mexican Revolution and was struck by a bus as a teenager, an incident which caused a broken spinal column, broken collarbone, broken pelvis, fractures, and a punctured uterus which led to infertility problems later on.
"Clockwork Orange," Stanley Kubrick's oddball crime film, features several teenage characters whose intentions are...questionable, to say the least. After all, Alex DeLarge, the main character of the story, sociopathically rapes a few women in his youth, runs around with a gang, and takes drugs.

Beyonce looks like a veritable MGM screen siren in her music video for "Why Don't You Love Me?", pulling of very retro curled hair, WWII bandanas, and and plush red lips. She pulls off a kind of dated that we envy rather than feel distanced from.

The basic tenet of origami is to create an object - a bird, cube, monkey, etc. - using a single piece of paper. And while for the most part this is possible, there are notable exceptions, including modular origami and this menacing red bull.
Tandoori chicken, which originates in India, is traditionally cooked in a tandoor, or clay oven, at high temperatures so that its complex marinade has the optimal conditions to sink in.
The side of one's head is not very flat, and might not seem like the best place to balance something round and hard to balance like a soccer ball.

Too often in the hustle and bustle of life we forget to take a deep breath, calm down, and embrace the quiet.

Doesn't sound so fun, does it?

In our hectic everyday world of coffee, office cubicles, kids, and soul destroying commutes, it's nice - and often necessary - to have a peaceful, safe haven we can come back to and just be ourselves in. Unfortunately, for those who live in overcrowded cities, that place is not home. What's worse is that most apartment buildings and even condos don't have garden space for you to calm your mind in.
Have you ever secretly pined away for a career in interior design, even though you're currently stuck in law school because, well, your parents forced you and gave you no other option?

We love yoga: it prepares us for the day ahead and stretches out any residual tension in our shoulders and back. But waking up at 6 AM in the morning and doing that first down dog can be...rough. That's why it's so important to stretch before you start your morning yoga routine.
You know how people who proclaim they can't draw always muddle through drawing assignments by piecing together a couple of stick figures? Well, that's because stick figures are the absolute easiest figures to draw.

Doing a hobby such as crochet usually offers no instant gratification - in fact, that's probably why we have this stereotypical image of a grandma sitting in her rocking chair, knitting endless bunches of scarves for her grandkids for hours on end.
V, the masked and rather offbeat/tortured hero from the movie "V For Vendetta," had a strange obsession with a particular letter of the alphabet, embellishing all his clothing and gear with a great big letter "V."
Crochet quilts, potholders, and mittens would just be endless jumbles of webs without the appropriate edges to finish them off and give them polish. There are many different ways you can create edges in crocheting, but the crochet foundation chain is among the more creative.

Cut the crap and make your own species of miniature humans in a zillionth of the time by watching this video by Jo Nakashima.
In mathematics, the order of operations define the priority in which complex equations are solved. The top priority is your parenthesis, then exponents, followed by multiplication and division, and finally addition and subtraction (PEMDAS). This video tutorial demonstrates the order of operation with various examples and explains the associated methodology. From Ramanujan to calculus co-creator Gottfried Leibniz, many of the world's best and brightest mathematical minds have belonged to autod...
