I'm back. School's an ass. On my quest for knowledge, which started approximately 3 years ago, I can upon an interesting little artifact. It is called the Arduino.
School internet filters serve a valid purpose—they keep students from wandering off into the deep corners of the web while still allowing at least some internet access. But a lot of these restrictions are completely ridiculous, to the point where some school districts block access to the educational material in National Geographic or forbid searching terms like "China," "Iran," or "Russia"—because, you know, breasts and commies.
BlackBerry has yet to find a home amongst the iPhone and popular Android phones, with sales plummeting over the last couple years, but this might be a thing of the past thanks to their latest device, the BlackBerry Priv. It has decent numbers so far and was even sold out on Amazon shortly after its initial release.
In the tech world, it's all too common to slap a fake label and packaging on a lower quality product, especially SD cards. If you've ever bought an SD card on the cheap from a slightly-less-than-reputable source (or even a reputable source, in some cases), how do you know if it's the real deal?
Everyone starts their mornings differently, but one common thread amongst the masses tends to be the consumption of coffee, albeit in many different forms—instant, pre-ground, K-Cups, Nespresso, and so on. And I'm sure that we all have our own preferred methods, as well.
Samsung's Galaxy series of devices have one common design theme that ties them all together—the physical home button at the bottom of the phone. This button can wake the phone, take you to your home screen, and even scan your fingerprint to securely unlock your device.
Few things are as frustrating as grabbing food from the fridge just to discover that your leftovers have gone bad. When it comes to cheese, you may have taken every last precaution to keep it as fresh as possible—sealed plastic containers, saran wrap, parchment paper—but to no avail.
Roughly four years ago, Adobe decided to abandon development of the mobile version of their popular Flash Player browser plugin. Their excuse at the time was that this move would enable them to focus more on HTML5 development for mobile devices and allow them to put more effort into maintaining the fluidity and security of their desktop Flash plugin.
If there's one thing that gets used far too frequently in the modern kitchen, it's the trash can. Home cooks everywhere waste enormous amounts of food by throwing it away before it's actually ready to be tossed.
Hello dear friends! I'm jgilhutton and I want to show you guys a Python wrapper I made a few months ago.
I'll bet this scenario will sound familiar to you: you're in the middle of making a spectacular dessert that will knock the socks off of your guests, and you've almost finished gathering all of your ingredients to create your mise en place. The last ingredient listed is powdered sugar, and you reach for where it's stored, when—drat! You don't have enough for the recipe.
In general, the fingerprint scanner in Samsung's 2015 flagship phones is quick and accurate, but when you get that "No Match" message while trying to unlock your phone, it can be incredibly annoying. To help curb these issues, I'll go over three tips for speeding up the unlocking process that should work wonders on your Galaxy S6, S6 Edge, S6 Edge+, or Note 5.
It's been a while, since I have just started High School. I have put a hiatus to my pentesting for a few weeks, and now, I am making a return. I have taken time to read about code, (even did a research article analysis on how humans can write "beautiful" code and something like that) and pentesting, but never made a full return. I will be occasionally coming back for a while.
Hello! I'm newbie at Null Byte and I want tho share some of my thoughts with you guys, hope you like it. I've been inspired by 3 facts for making this: 1- The post 'How to write better code', 2- A few illegible comments at some posts, 3- I myself have never written such a long text in English, this will be my first one!
There are a few key ingredients that you always need on hand when baking cookies and other desserts, but when you run out, you run out. You either have to stop what you're doing and go to the grocery store, find a good substitute, or scrap the project entirely. Chances are, you'll never accept defeat, and why go to the store if there's a good substitute on hand?
There are rules that cooking in general always follows: cakes should be fluffy. Steaks should be heavily seasoned, and nowhere near a bottle of steak sauce. Every stock should start with aromatics (onions, carrots, & celery). And, until very recently, meringues should always be made with egg whites.
Programming is an essential thing in hacking/pentesting, and at times, I do not feel that it is being addressed enough here, at Null-byte. I understand that this is a forum dedicated for hacking, but I'll address some of the stuff I feel is muy importante about programming. I am not a professional programmer, but I do have experience and I do want to share some of the stuff professionals have taught me.
The grill isn't just a place for burgers, dogs, and corn anymore. Fresh fruit has made its way into barbecue territory, with results so good, you'll think twice about settling for fruit salad. While some fruits are common enough on the grill (like pineapple), these six are more off the beaten trail: peaches, watermelon, strawberries, mango, and pears.
When I was a little kid, I was obsessed with shells. And while most of my shell collection came from combing the beach for treasure, some of it came from a different source: dinner. Whenever my parents had fresh clams or mussels, I would take the leftover shells, soak them overnight in soapy water, and add them to my collection.
The peanut butter and jelly sandwich has officially left the building. When you eat this every other day in elementary school, you've sort of reached your limit. The thing is, peanut butter itself is delicious and quite versatile if used in the right way. Let's explore this kitchen cabinet staple and showcase it via the three dinner courses.
There is no greater food to master than steak. If you can make a steak that's only marginally better than your neighborhood Applebee's, you'll still have friends waiting outside your door for steak night. And if you can make steak as good as that expensive gourmet steakhouse you went to for your birthday? Well, your popularity is about to increase dramatically.
Most primary cocktail ingredients just sound delicious. Lime and tonic water? Yes, please. Bitters and simple syrup? Sign me up. Egg whites and... wait... egg whites? In a cocktail?
In my opinion, vodka gets a lot of undeserved flak. It seems like most people have a bad experience in college with a plastic bottle of vodka and never go back. I can't blame them; it took me a few years after graduating college to start to enjoy vodka again—but now I adore it.
Brought to you by Purdy Paints The art of painting requires excellent tools. And with so many options on the market, it can be hard to find a brand that works for you and your DIY project. That's where Purdy comes in.
Hello, Hackers/Viewers! My name is nullf0x, and I have 4 years of experience as a hacker. You might see everyday that one of your friends or acquaintances get a new virus in their computer. You might think, How cool would it be if I made a virus? or How cool would I be if i could remove viruses from others computers for money or free?
Ad blocking on Android usually requires root access, but a pair of new browsers based on the open source Chromium and Firefox builds are looking to change this.
Carriers like to distinguish their Android phones from the competition by making small changes to the interface here and there. This practice is so common that Android now has a built-in system for managing these small tweaks.
Android Debug Bridge (or ADB for short) serves as a remote terminal interface for executing shell commands on any Android device. Put simply, ADB lets you send commands from your computer to your phone or tablet, some of which would require root access if they were performed on the Android side of the connection.
When it comes to app permissions, Android takes an "all or nothing" approach. You have no granular control over what data apps can access, so the only way to prevent an app from seeing your location or starting up on boot, for instance, is to not install the app in the first place.
While honey is one of the most popular ingredients on kitchen shelves the world over, honeybee pollen is still a relatively rare find in most households. It's not hard to guess why: eating pollen just sounds weird... it would probably sell a lot better if it had a more appetizing name, like honey. Furthermore, it looks unlike any other common ingredient, and the smell can be off-putting to some. But it's good, it's healthy, and it's altogether pretty awesome!
Greasy fast food. Snacks. Candy. Empty stomachs. What do these all have in common? They're all things that people commonly have for lunch during the week, because it beats the hassle of having to plan, make, and pack lunches before their workday.
If beauty is in the eye of the beholder, music lies in the ear. Even within a group of friends who share enough common interests to sit around and socialize over, music tastes can vary dramatically.
Sushi aficionados and Simpsons fans alike know all about the joys of fugu. Known also as blowfish, it's reputed for being tasty if sliced from the correct part of the animal and many even say they experience a "fugu high" after eating the fish. Alas, if you have an unskilled chef, fugu is famous for being deadly.
Those ordinary green zucchini you see in the market are hiding a lovely, delicious secret: Actually, all summer squashes produce these delightful blooms, but the zucchini's are most frequently used for eating since they taste the best: fresh, clean, and zucchini-like, but with a little something extra. They used to be a rarity at supermarkets, so you had to have a garden or a gardener friend who would generously share the bounty with you.
We've all been there: facing a lengthy, complex word that ignores the phonics we were taught in elementary school, unsure of not only its pronunciation, but also its meaning. These words, from autochthonous to esquamulose, are both terrifying and impressive. After all, if someone knows how to use them—and even say them—they must be quite smart. Yet before you begin stuffing every email and presentation with verbose prose, you might want to reconsider what others perceive to be intelligent.
Are you stranded in a hotel room with no kitchen, but craving the comfort of a home-cooked meal? Fear not, I have found some interesting ways to cook food without the luxury of an oven, stove, microwave, or even a toaster!—also known as "hotel room cooking."
If you have ever attempted to mix and shape your own meatballs or burger patties, you may have endured bits of meat continuously and stubbornly sticking to your hands. This can make shaping more challenging than it should be.
There's a common bug that affects many Samsung Galaxy S5 users, myself included. The software that drives the fingerprint sensor can randomly fail to load, leaving you without one of the most unique features of your beloved smartphone.
