"Though iPhone and iPad apps are generally very stable, sometimes you'll encounter an application that crashes at random. In iOS, a crashing app usually presents as an app that seems to quit itself immediately, returning back to the Home Screen of the device without user intent. An app crash can happen immediately upon launching the app, crash randomly in the middle of using the app, or sometimes a crash can even be triggered predictably by a particular action that is attempted within the application. Regardless of when the iOS app is crashing, we're going to review a few solutions that nearly always work to remedy the problem and should get you on your way to a trouble-free app usage experience again."

"At about this time last year John Green launched Crash Course World History. That video series now contains 42 short video lessons on World History. Today, John Green launched a new Crash Course series. This one is all about U.S. History. The first video in the Crash Course U.S. History series is now up on YouTube. I've embedded it below. The series starts before Europeans arrived in North America."

"One of the biggest learning trends you should know about is project-based learning. Basically, students are given a task and allowed to work in groups to deliver solutions to a problem. This is an applicable methodology in science, technology, math, arts, etc. You name it, project-based learning could likely be used. But how do you get started with a new way to teach? That's a major question that often stops teachers right in their tracks. It's hard to switch up what's been working in the past. It's impossible to figure out how to integrate a new classroom structure in the small amount of time available to educators around the world. In an effort to help solve this issue, our friends at EdTechTeacher have created what's essentially a crash course in project-based learning. The video is about an hour long and is by Suzy Brooks, a third-grade teacher in Massachusetts."

"You learned how to Zoom, or Hangout, or Team up. You read all the quick tips about emergency remote teaching. You recorded your lectures or gathered via video call with however many students you could reach each week. You pivoted, shifted and, let's be real, maybe stumbled into a makeshift version of online education. At last, final grades-or pass/fail marks-are turned in. Congratulations, you made it through the virtual semester. Now what?"

"We all know that leadership is important in education. Without strong leadership, education initiatives tend to crash and burn. Consider professional learning. Leadership is one of Learning Forward's seven Standards for Professional Learning -- evidence-based standards that outline the characteristics of professional learning that lead to effective teaching practices and improved student learning."

"McGonigal's remarks included a bevy of interesting facts about gaming, as well as a group play exercise - what she called "massively multiplayer thumb wrestling" - and peeks at two of her recent alternate reality games: EVOKE (2010), a "crash course in changing the world"; and Find the Future (2011), which challenged 500 student authors to write a book in one night while inside the New York Public Library. Here are five key things McGonigal wanted ISTE 2013 attendees to know about gaming and education:"

"It's a golden age of education podcasts. Teachers, professors, education innovators, and tech skeptics have switched on their microphones to share their insights and analysis-and you'll find plenty of lively characters and fresh voices via your earbuds. After all, let's face it, teachers can be great talkers (we mean that in a good way), and they're also seasoned storytellers. Check out the latest reboot of the EdSurge On Air podcast! Take Michael Wesch, for instance. Inspired by the long-running radio show This American Life, he tags along with his students to better understand their lives and struggles on his Life101 podcast. (That includes crashing a frat party-you'll want to check out that episode). Other education podcasts take a more Socratic approach, drawing out their guests through dialogue. When asking around, several folks we talked to praised Teaching in Higher Ed as a podcast with particularly engaging discussions. Below are our favorites (including our own podcast, which relaunched this week), organized by topic. Please share your own picks in the comments section below."

"If you ask any DIY fanatic what's on top of their wish-list, chances are pretty high they'll say a laser cutter or engraver. As you might expect, these exotic pieces of kit use high-powered lasers to cut through materials, or to engrave them with a design. Like a 3D printer, they're controlled by a computer, and work autonomously once provided with a design. Laser cutters aren't terribly new technology, and haven't quite captured the public attention like 3D printers have. However, they are incredibly cool, and much like 3D printers, prices have crashed to the point where they're now affordable for DIY enthusiasts. Which brings us on to a really interesting question: What one should you get? What can you make with it? And crucially, what should you do to ensure that you use them as safely as possible?"

"Imagine if we taught pilots to fly without ever letting them in a cockpit. Or gave them the keys to a commercial airplane without the required hours-or years-of hands on training and practice. Sure, we'd show them plenty of PowerPoint presentations and make them sit through a few seminars on the theory and physics of flight, but then we'd slap on a graduation cap and let them take off into the big blue sky. Not only would it likely be ineffective, it would be borderline criminal. Yet when it comes to professional development for classroom teachers, that's almost exactly what we do. Most professional development opportunities for educators are still lecture style - telling, showing, and explaining how something can be done. And when the 'learning' is finished, we push teachers onto the runway with a cabin full of students and wish them luck. Predictably, many crash and burn."

"You bought your iPad new three years ago, and now it's getting a bit long in the tooth. Opening apps can take forever. Sometimes they crash, stop responding, or won't open to begin with. If you want to extend the life of your little glass rectangle-and make your iPad faster in general-the following tips can help. And all of these tips are simple(ish)-nothing crazy like jail-breaking or changing hardware."

"Music is creative, enjoyable and an excellent means of expressing oneself. Even better: playing an instrument is one of the best workouts you can give your brain. Even if you don't intend on pursuing a career in music or starting a band, you only need to know the basics of an instrument to enjoy it. YouTube can teach you to do just about anything, and that includes playing an instrument. Today we'll focus on piano, guitar, bass guitar and drums, but if you look hard enough you'll find crash courses in everything from the bassoon to the melodica."

Whenever you install something in Mac OS X then it gets installed from package files. Along with installing something from package files, a "Bill of Materials" file is stored in the package receipt file. These ".bom" files contain a list of the files installed by that package as well as the proper permissions for each file. But, in future, these permissions can get changed resulting in freezing or crashing of your Mac.

In case, your computer crashes then you can lose your most important data like photos, professional documents, etc. Thus, taking back up of your computer data is very useful.

It is really very frustrating when you lose data due to hard disk crash or any other computer problem. Whether it is family photos, music collection or any financial data, keeping it safe is your responsibility. Thus, regularly backing up your data and settings is highly recommended.

"Multicopters are one of the hottest consumer gadgets on the market, and for good reason. They're cheap, easy to fly, a ton of fun, and by far the easiest way to get into radio controlled flying. This Drone School series is our way to help new flyers get off the ground, and over the next few weeks we'll get into some exercises to build your skills and capabilities for maximum fun with minimal crashes. For starters, let's look at how to pick a good beginner quadcopter."

"In December our hackerspace, Crash Space in Culver City, hosted an Instructables Build Night featuring Chibitronics Circuit Stickers. With Channukah around the corner, I thought an LED menorah would be a perfect project to see what I could make with the stick-on circuits. When celebrating Channukah, the candles of the menorah are lit each night, one for the first night, two for the second, and so on until the eighth night, when they are all lit. The middle candle is lit first each night, and is used to light the other eight candles. My goal for the LED menorah was for it function like the candles, with the center always lit, and an additional LED "candle" lit each night. I also wanted to set it up so that lighting the LED's each night didn't require additional construction. As you will see, the goals were met and turning on each additional LED was done using a pull tab, which allowed all the taping and construction to be done ahead of time."

"I recently discovered Boclips for Teachers, a portal hosting more than 2 million short-form educational videos from more than 100 of the educational video producers you already know and love. Familiar sites like TED-Ed, LearnZillion, Associated Press, PBS, Crash Course, Reuters, Bozeman Science and Smithsonian have offered permission for the site to curate their excellent content in a distraction-free, ad-free environment. Content is selected by teachers for teachers. Boclips for Teachers spans age/grade levels and disciplines. Content includes instructional video, animations, mini-documentaries, historical footage, breaking news and virtual reality. Teachers may use the platform to share, edit, and store videos or they might easily copy BoClips links to share on their own websites and learning management systems. Unfortunately, the search does not yet allow users to filter for subject, age level, curriculum standards, etc"
