Welcome back to another tutorial on functions. Last time, we looked inside memory to see what functions looked like in the flesh and all that Assembly was pretty nasty. At least you have some exposure to it. This time, we will be examining how functions work with the stack.
Welcome back! In the last iteration of how to train your python, we talked about functions, and we even made our own! We're going to move on to more types of data arrays (much like lists) in today's discussion.
Welcome back! In the last iteration of how to train your python, we covered loops, today we'll be covering something that I wish I had learned about much earlier in my scripting career, errors. We all run into them, and they can be frustrating, but there is also a silver lining to them. Today, we'll be discussing why some errors are unavoidable, and what we can do when we run into them. Also, this article will be more of a concept and less of writing actual code, but the information is equall...
If you're a U.S. expat living, traveling, or studying abroad, or just someone who typically uses virtual private networks (VPNs) in order to access the North American video libraries of services like Hulu or Netflix, you were probably surprised to see that these video streaming services don't work on your Chromecast or Chromecast 2.
If you haven't come up with a funny, innovative costume yet for Halloween, you're running out of time. While all your friends are busy perfecting their month-long DIY costume project, you're still being lazy about it and have just now started to search online for ideas.
Last time in how to train you python, we covered the basics of variables and output. While we were covering variables, we talked briefly about strings. "String" is just a fancier way of saying "Word". A string is simply a set of characters encased in quotations, this lets python know that it is a word. Sometimes when we do things with strings we'll need to change them in order to do something. Python is case sensitive, for example "Null-Byte" is not the same as "null-byte". This is where mani...
First of all, I hope the title makes sense. :D Well, this is basically creating a program that can help with dictionary attacks. Generate possible passwords. It pretty much lies in you knowing the person you want to hack.
A while back, I wrote review of my favorite hacking movies of all time. Two of my key criteria were; (1) how realistic was the hacking, and (2) are the hackers portrayed as the "good guys." This past winter, a new hacker movie was released, appropriately named Blackhat starring Chris Hemsworth (from Thor fame) as a blackhat hacker who is released from prison to stop a notorious and destructive hacker that only he can stop. Although the movie did very poorly at the box office, I thought it was...
Apple's streaming music service, Apple Music, offers a three-month free trial that hopes to get you addicted enough to pay for a monthly subscription. You may even see a one-month trial if you're a former subscriber. While it's not very obvious, there is a way to cancel either free trial from auto-renewing. That way, you don't have to deal with Apple support to try and get your money back because you forgot.
Google made a huge splash this year in their annual Google I/O with an awesome announcement regarding their Photos app. Although I was primarily interested in the details surrounding Android M, my ears instantly perked up when Google announced that their Photos app will now offer free, unlimited, high-quality storage.
In the era of smartphones and cloud-based computing, it almost seems irresponsible to keep a stash of paper documents. Not only is a physical paper printout environmentally impractical, it's also a lot harder to organize and keep track of than a digital file stored on a hard drive.
Big box stores love to sell gift cards, and as consumers, we snap them up almost as quickly as they can be printed. This industry has become rather profitable, though, because portions of the gift card balances often go unused.
Welcome back, my aspiring hackers! Those of you who use Windows in a LAN environment understand that Windows machines can share directories, files, printers, etc. using "shares." This protocol dates back to the 1980s when the then dominant computer firm, IBM, developed a way for computers to communicate over the LAN by just using computer names rather than MAC or IP addresses.
Welcome to the first chapter of Excel is Simple, a place where we will burst all myths around excel and try to make it simpler and fun to use.
Loaded with a gorgeous display and a powerful processor, the Kindle Fire HDX is an impressive all-around tablet, especially when it's used for what Amazon Kindles were built for—reading electronic versions of novels, textbooks, and other printed works.
Like Costco's price codes or the tags on your bread, the numerical codes printed on those sticky little fruit and vegetable labels can reveal a lot of information to us consumers. Once you understand the codes, you can look at that little label (also known as PLU, or "price look up" label) and know whether the produce you're about to buy or eat was treated with pesticides, genetically modified, both, or neither. Before we go any further with deciphering the codes on these labels, let's take a...
If you're as bad at locking your Nexus up as I am, you have the "slide" option set for your screen lock. It may not be the most secure option, but it's definitely the easiest way to unlock your device while being able to utilize lock screen widgets.
One feature of Samsung devices that's less useful than I had expected is S Voice, the voice assistant that ships with all new Galaxy devices. The voice is annoying, the features are lacking, and it's an all around subpar product. With Google Now, Siri, and now Microsoft's Cortana, Samsung needs to really step up their game—even on the new Galaxy S5.
Some people put up their holiday decorations as soon as Thanksgiving is over. Some wait until Christmas Eve. Right now, the only thing in my whole apartment that would tip you off is a tiny little fake tree on the counter. I've been planning on decorating all month, but I haven't quite gotten around to it yet.
Some women see Halloween as a once-a-year opportunity to dress in something skimpy without dealing with as much scrutiny as usual. That can be fun, but not everyone is comfortable enough wearing so little, and the costumes are so boring and repetitive. Some of us just don't feel like freezing.
Everyone hates to feel like they've been taken advantage of, especially when buying a used vehicle. The thought comes across every car buyer's mind... "Did I just get taken by that smooth-talking salesman?" When it comes to cars, how do you know if you're really getting a good deal, or if you're being offered a fair price for your car? After all, cars are most peoples second largest investment, so we need to make this decision wisely.

Prepaid phones are becoming more and more popular, and tons of people can see the benefits of switching now that some companies are offering prepaid services that are on par with the big players. For a lot of folks, the only thing keeping them from switching is the huge early termination fees that service providers charge to break a contract early.

If you have children, then you know firsthand how many crayons parents end up buying. There is no such thing as using a crayon until it disappears. Kids use crayons until they are a nub, and then they toss the crayon aside, never to use it again.
To some, SCRABBLE is just a board game to play during family game night or during a casual get-together. Others think of SCRABBLE as a mere hobby. But with any activity, there will always be fanatics—the ones who would rather sell their soul than stop—the ones with a constant yearning for self-improvement—the merciless.

You know that you have the Gmail app on your iPhone. After all, you get Gmail notifications, you see it in the app switcher, it's in the Settings app, and there's an "Open" button in the App Store instead of "Get" or a download icon. But you cannot find the app on your Home Screen. If this situation sounds like something you're dealing with on iOS 14 or iOS 15, there's an easy answer.
At first glance, it may not sound like there's much value in doing a crossword puzzle in augmented reality, but The New York Times has managed to revamp the pastime as an immersive game.
While the job market is slowly rebounding, competition remains fierce. Don't get caught behind when a new opportunity presents itself. Preparation is key to landing your new big job.
You may be familiar with image-based or audio-based steganography, the art of hiding messages or code inside of pictures, but that's not the only way to conceal secret communications. With zero-width characters, we can use text-based steganography to stash hidden information inside of plain text, and we can even figure out who's leaking documents online.
While some people might like Thanksgiving because of the food, seeing family, or another wholesome reason, many of us also enjoy saving big on the items we've been eyeing all year. Take iPhone cases, for example. Speck, Insignia, even Apple all make cases that can put a dent in your wallet. A good Black Friday deal can mean a shiny new case for your iPhone and some extra dollars in your pocket.
KeePassX, 1Password, and LastPass are effective against keyloggers, phishing, and database breaches, but passwords managers rely on the operating system's clipboard to securely move credentials from the password vault to the web browser. It's within these few seconds that an attacker can dump the clipboard contents and exfiltrate passwords.
With an inconspicuous Android phone and USB flash drive, an attacker can compromise a Windows 10 computer in less than 15 seconds. Once a root shell has been established, long-term persistence to the backdoor can be configured with just two simple commands — all while bypassing antivirus software and Windows Defender.
With the list of available mobile apps for moviegoers constantly expanding and improving, seeing a film at your local theater has never been better.
