In 1987, two brothers, Thomas and John Kroll, began work on an image editing software, which was eventually acquired in 1988 and released to the world in 1990 by Adobe. That software was Photoshop 1.0, initially exclusive for the Macintosh platform. Over the years, Photoshop became a great wizard of image editing and gained application rockstar status.
Have you ever been using your computer when a friend randomly decides it's time to start up a text message conversation? You usually have to stop what you're doing on the desktop, then go pick up your smartphone and respond to the text. Then, if your buddy replies with another message, you have to juggle back and forth between your mouse and keyboard and your handheld device.
One of the first orders of business after purchasing a new smartphone is to load up your shiny new toy with phone numbers, email addresses, and general contact information for all the important people in your life.

The wait is over. The Samsung Galaxy S6, arguably the best Android phone of this year, has just launched. There was already a lot of hype about this super phone—its looks, its specifications, and its other functions have been under the microscope for quite some time. It will not be a good idea that you take this phone in your hand and use it in the same fashion as you have been using your other phones in the past.
Macarons are a sweet meringue-based confection made primarily from almond flour, sugar, and egg whites. They are usually filled with buttercream, curd, or ganache. A true fat cow cook will tell you that macaron is pronounced (mah-k-uh-rohn). While it's technically not incorrect to call them macaroons (mak-uh-roon), this usually refers to coconut cookies.
Welcome back, my fledgling hackers! In an earlier tutorial, I introduced you to probably the most popular scripting language for hackers, Python. To become a professional hacker, you need to have some scripting skills and Python is a good choice if you want to master just one. In this latest guide, I will expand your background in Python and offer you a tidbit of Python code to whet your appetite for all of the hacking to come.
The internet is forever. When you put something out there, it can easily be re-shared, floating from server to server indefinitely with no way of taking it back. It's a scary thought when you consider that a young adult's grandchildren will one day have access to their drunken party pics.
When it comes to getting your computer and smartphone to work well together, there's no service more robust and capable than AirDroid. For years, it's been the go-to tool for users looking to transfer files between their devices or access contact lists and call logs from their computer.
Holidays are a time for good food and good drink, but more often than not, we substitute good drink for, well, cheap drink. However, cheap wine doesn't have to be bad.
Google's new Inbox by Gmail service wants to fundamentally change the way you handle email, so a bit of a learning curve is to be expected when you're first using the utility. As of right now, the service is invite-only, but if you were lucky enough to get in on the ground floor, you're probably wondering, "How the heck do I use this thing?"
Staying healthy is a progressive challenge we all face throughout our lives, and figuring out just how to do that can be a challenge when it's not your job. For doctors, however, it is. Here's how they keep themselves healthy day to day.

Although it might seem like a simple and straightforward exercise, those of you who have attempted password cracking know that there are many subtleties to this art.
If you're anything like me, every time you travel you end up in a desperate panic for a decent W-Fi connection. Whether you want to post your photos, research the best beaches, or kill time during an overnight layover, a hotel's Wi-Fi quality is of paramount significance in making a reservation.
There are so many things to love about the Nexus 5, from timely updates to newer versions of Android to a terrific blend of price and specs.

Welcome back, my apprentice hackers! As many of you know, I have been hesitant to adopt the new Kali hacking system from Offensive Security. This hesitancy has been based upon a number of bugs in the original release back in March of 2013 and my belief that BackTrack was easier for the novice to work with.
Welcome back, my greenhorn hackers!
For my money, one of the greatest improvements brought about from the smartphone revolution is the advent of visual voicemail. No longer do we have to slog through dial menus or trudge through every single message to get to the next. We can just look at our messages, right there on our screens, organized neatly like emails or text messages.
Sometimes... no, most of the time, I don't want to do anything, so I was excited to find a developer teaming up with Sir Isaac Newton to create an application that encouraged my slothfulness.
Former Vice President Dick Cheney was so fearful of attacks, he had his heart defibrillator re-calibrated to block incoming wireless signals so that highly skilled hackers couldn't send him into cardiac arrest.
Sometimes, doing the right thing is way more difficult than it should be, like trying to return a lost smartphone. Despite having the best intentions, it's often hard to track down the rightful owner, especially if the device is armed with a passcode. On the other hand, there are plenty of people who see an unattended iPhone or Samsung Galaxy S3 as a chance for profit. In 2011 alone, the number of lost and stolen cell phones in America was worth over 30 billion dollars. That's right, billion....
There are two options when it comes to a dent in your car — live with it, cringing each time it enters your view, or get rid of it. While the latter is obviously the best option, most of us will probably just live with dents and dings since spare money is better spent on the actual functionality of the vehicle. However, there is a way to knock out automobile dents yourself with relatively little cash in the bank.
I was kinda disappointed with last year's James Bond movie, Skyfall. Don't get me wrong, it was a solid flick, but only made me jealous with all its super spy hacker stuff.
There's nothing worse than holding an ice cold brewski on a hot summer day and having no way to open it. If you're a Bud fan, you'll have no problem opening the bottle because most mass-market beers have twist-off caps. But if you have a taste for finer, more expensive brews, you'll more than likely run into the pry-off caps. Pry-offs are used mainly because companies believe it provides a better seal against one of beer's greatest enemies—oxygen. Plus it's a cheaper alternative for craft bre...

It can feel hard to find time for just about anything these days. But if you really sit down and think about it, you likely have a little more free time in your day than you might actually imagine. The average person has about 4.5 hours of total leisure time over the course of a week.
As more and more people use the video conferencing service Zoom, the chances of trolling behavior and attacks only increase. But it's not just "Zoombombers" you need to worry about. A heated discussion between family, friends, or colleagues could turn sideways real quick, and sometimes the best course of action is to remove the participant from the group video meeting altogether.
In the pursuit of large displays with thinner bezels, Samsung has sacrificed some components. While the loss of the headphone jack gets all the attention, there are other victims — namely, the notification LED.
Samsung put some of the industry's most advanced camera tech in the Galaxy S20 series. However, their image processing still lags behind the Google Camera app found on Pixel phones, so the end result is good but not great. Luckily, you can install a mod to pair that beastly hardware with arguably the best camera software.
On stock Android 9 and 10, it is easier than ever to take a screenshot and quickly edit the captured image. However, the downside to that convenience has manifested itself in a heads-up notification that can also get in the way.
One of the main goals of Google Wifi (and Nest Wifi after it) is to make managing your internet connections as simple as possible. A great example of this is how easy it is to prioritize one device and allot it more bandwidth when your network is bogged down with other traffic.
