Welcome back! In our last training session we covered classes and how OOP can make programming/scripting easier. Today we'll be taking a breather and covering something fairly simple, bitwise operators.
Those of you who have been a part of the Null Byte community for even a short while know that I sincerely and firmly believe that hacking is the most important skill set of the future.
You're at your friend's house. All you've heard about all day is his new laptop. He's got a brand new top-specced MacBook Pro, and he won't stop going on about it. It particularly annoys you as all you've got is a 4 year old cheap laptop, even if it is running Linux.
Televisions used to be great for just one thing—watching TV. But a more connected world brought with it Smart TVs, devices that can access the web, stream Netflix, and even mirror your smartphone's display. And with this level of connectivity, OEMs like Samsung saw it fit to place targeted and interactive ads on your screen.
The future: that time that lies ahead, unknown and overwhelming. Whether you're an obsessive planner or someone who can't think more than two days ahead, considering the future can be frightening with all of the "what ifs." Don't let the future keep you awake at night—in fact, the less you think about what life holds in store for you, the better off you'll be.
Investing is like exercise—we all know we should be doing more of it, but we often just can't find the time. I mean, really, who's got the hours, inclination, and skill to pour through volumes of data and put together a balanced yet sophisticated portfolio of investment vehicles tailored specifically to optimize their returns while mitigating potential risks. Not me, that's for sure.
I'll freely admit that I'm a SwiftKey diehard. I've used the keyboard since its inception in 2010, and it was one of the first apps I ever paid for back in the days of my beloved Sprint Evo 4G. Since then, I've kept up with all its beta iterations, and have unabashedly installed it on various friend's devices.
Google recently updated their TOS to reflect the email scanning practices they use in Gmail, which are used to display more relevant ads, among other things.
Dropbox, the cloud backup tool that is a mainstay on many of our devices, has added two companion apps to its service. Earlier today, we showed you a glimpse into a new testing version of the Gmail app, with features like pinning and snoozing to keep your inbox in check. Now, Dropbox has released Mailbox for Android, about a year after they purchased the company and its iOS app, with a simple goal: taming your inbox.
I used to have nightmares when I watched Terminator 2. I mean, I didn't step on a playground for a least two months after I saw that movie. There was something terrifying about computers having so much intelligence.
Assembling a gingerbread house is the bread and butter of a lot of Christmas Eve and Christmas Day celebrations, but anyone who has tried to do so on limited time knows it's harder than it looks.
Faux bois is a fancy schmancy French term for fake wood. And faux bois prints on furniture, pillows, as wallpaper, and even as ingrained barks of chocolate are all the rage right now.
In this tutorial, we learn how to write a literature review for thesis writers. The three elements are: discuss the most relevant theory, introduce and define key terms, and discuss recent research in the field. You will need to include the most important literature, quote directly only if you discuss at some length, and use indirect quotes as well. Focus on notions you will use in your empirical study. It should be ten pages or less and sources of all quotes must appear in your works cited p...
The term blog is a shorthand for web-log. It can be considered as a online and publically viewable diary of user generated content usually sorted by date.
A video that demonstrates one of the basic techniques involved in factorizing an equation that contains the difference of two terms which are also perfect squares themselves and are equated to 0.
In this video, we learn how to understand completing the square. First, you will write the quadratic expression out. Then, you will write the open bracket so you write it out in the correct format. Now, find the number in front of the 'x' term, which is the coefficient. Then, write this number on the other side of the equation in the parenthesis. From here, you will need to follow the proper rules of math to find out what the square is equal to. When you are finished, make sure you label the ...
In this video, we learn how to understand negative exponents. The one rule you have to remember is when you have a number with a negative power, then you need to divide it over one. You can take this term and put it in the denominator of your fraction to make it a positive exponent. For example, if you have 5 to the -1, then you can move the 5 to the denominator and get 1/5, which is the same exact thing! This is one of the most basic rules in math. Once you understand this, simplifying fract...
In this video, we learn how to calculate a limit at infinity with a radical. The idea is to take out the higher power of 'x' in the denominator first. If the x squared is under a radical, take that out so you're left with just 'x'. After this, divide every term by 'x'. Once you are finished with this, you can rewrite the equation. Next, you will use the rules of math to find the answer of the equation. This is hard math to do if you aren't used to it! Make sure you practice with the samples i...
"Harajuku" might sound slightly familiar to you - Gwen Stefani used the word to name her "Harajuku Girls" fashion and perfume line. But other than the cutesy little Japanese dancers she had during her tour and lots of bright clothing and makeup, what is a Harajuku girl exactly?
This is a video tutorial in the Education category where you are going to learn how to describe chemical formulas. A chemical formula represents the actual number of atoms of each element within a molecule. Different visual representations of molecules include the ball and stick three dimensional model, a line drawing that represents the structure in two dimensional terms, and a shorthand used by organic chemists. If a molecule has 4 green atoms and 2 orange atoms, the ratio of green to orang...
In this video Donnie Smith shows you how to apply primer surfacer. In addition to the visual instructions on the video, you can follow along with the instructions below from Donnie himself. After watching this video, you'll be an expert on primer surfacing!
In this tutorial, we learn how to find the interior and exterior angles of a triangle. I triangle has three angles and their measurement when added together will equal 180. For example, if one angle is 80 and another is 30, then start off saying the equation equals 180. Write in 80+30+X in front of the equals sign, then subtract the combined like terms from the 180. After this, you will have found the value of x, which will also be the measurement of the last angle. Make sure to write out the...
In this tutorial, we learn how to understand fractional exponents. Starting with an example, let's say you have the square root of four as an equation. The answer to this is two. A fractional exponent is not much different than this problem. Let's say you have 4 to the 1/2 power. This would be equal to (2 squared) 1/2. Now, using the third exponent law, the term becomes 2 to the power of two x 1/2. This will leave you with the answer of two. Now you know how to get the correct answer and can ...
In this tutorial, we learn how to find abc, curve direction & y-intercept (quadratic eq). First, you need to find the a,b, and c of the equation. A will equal what the coefficient is in the equation, B will equal the second, and C will equal the third term. This tells us if the numbers are positive or negative, so so know if the parabola opens up or down. To graph C, you will know what the y-intercept is going to be, then find the matching units. After this, you will use B to shape the parabo...
Despite what this cookie's name may imply, these monster cookies are not in any way related to monsters or to Halloween. Rather, the term "monster cookies" comes from the simple fact that these doughy goodies contain everything you could possibly imagine a cookie to have.
In this tutorial, we learn how to understand a securitization. This is a type of structured finance that has three key elements. the first is that there is a pooling of credit sensitive assets. In pooling the assets, you introduce diversification. The second element is to transfer credit risk to the third party and make rules around whether there has been a true transfer of credit risk. The third element in this is trenching of liabilities. This means when cash flows are transferred to a spec...
Who said you could only cook one type of ethnic cuisine at a time? Define the term "fusion" by whipping up this chicken with cardamom-orange butter. The cardamon and orange add a scintillating dose of rich, Indian-inspired curry-like flavor that'll take your chicken from blah to mindblowingly delicious.
Unless you're a music theory buff or taking AP Music Theory in school (forced or otherwise), then the only word in "diatonic circle chord progressions" that makes sense to you is "circle." But the fancy schmancy term is just an elaborate way of saying you're playing chord progressions based on the circle of fifths.
In order to install steam games on a Mac without Windows, you'll to download the Crossover application. After you have the Crossover software, place the CD in your hard drive. Click on "Install Unsupported Software, after you highlight it in the list. Click "continue". Rename the bottle. Click on create. Click continue. Follow the install wizard through, accepting the terms and clicking "next". Register your product ID, if you haven't already done so.
If you're in a committed long-term relationship then you're stuck with the person. You're probably thinking, "um, yeah, I already know that," but have you factored this variable into how and what you and your partner fight about?
Yeah, we know the title of this video sounds confusing (dichroic what?), but a tri-strand necklace with a dichroic glass pendant is simply a fancy term for a necklace composed of three strands with a glass pendant hanging from the bottom.
Okay, so we have to admit something to you: This isn't actually an origami craft in the strictest sense of the term. Origami dictates that an object be folded into being from a single sheet of paper, but for this goldfish we take a bit of a shortcut, literally. Instead of folding to get all the pieces in place, we make a few cuts to facilitate the fish-forming process.
It doesn't matter how great a photographer if you don't have the right tools. Even Annie Liebvitz would get only average shots with a lower grade digital camera because it's very limited in terms of settings that you can control.
Victory rolls may not sound like a familiar term these days because almost no one does them anymore. But you'd sure recognize them if we showed you some photos from the 1940s and 1950's: Actresses like Rita Hayworth and Katherine Hepburn loved wearing them, and as they did so did the rest of the nation who looked to them for beauty inspiration.
The circle of fifths sounds like some sort of "Lord of The Rings" council of high elves, but all this term really denotes is how major and minor scales are connected on the piano (a lot more boring than the high elf stuff, we know).
Bobs, both long (affectionately termed blobs) and short, are the hottest hair trend in Hollywood right now. A-listers like Eva Longoria and Victoria Beckham, who love the liberated, "modern girl" effect a bob tends to give off, have made the haircut high in demand at major salons.
To solve a Rubik's cube, you will need to begin by keeping in mind the 7 steps. To learn about the cube itself, you will need to take it apart. The cube has 3 types of pieces. The center pieces do not move. They are actually fixed. Every piece is unique, and every piece has a unique place.
A cicada is a fancy term for a flying cockroach, and though it may seem strange - not to mention disgusting - to want to make a cockroach replica out of paper, we promise that the paper version is much cuter and won't pee on you like the real ones would.
In order to kill bed bugs with a dry ice trap, you will need the following: a dog bowl, a towel, a cooler, a cotton ball, painter's tape, and talc powder.
So after much hard labor and patience, you've finally thrown your first vase, fired it carefully in the kiln, and let it harden to a fine finish. What to do next in your pottery making journey? While a beautiful vase is a beautiful vase no matter the finish or color, applying a glaze is like putting on makeup: sure, you don't NEED it, but having it on dramatically improves and accentuates your features, making cheekbones more sculpted, eyes wider and brighter, and lips more well defined. In t...
