In Java, you can use the command Runtime.getRuntime().exec to execute shell commands, or any external system command. Here's a handy example. Bash has your back.

One of the worst things that can happen to you is your code being a failure, and in extension, causing damage to a bigger picture as in: delaying (or breaking down) the project and the business, pulling down the sales, or generating any money/time/or hardware loss. It could happen in the worst of the moments, and in the least expected scenarios. What is a coder to do when his program goes wrong and every finger is pointing on him? Success usually has many parents, failure remains an orphan until they figure out a way to put it on you.

Why so paranoid? Simple. Because I care about my work, photos and data and I would be sad if I lost it. Think about all the times you've heard about a friend who has lost everything. A decade of photos. Years of email. It hurts- just like exercise - because it's good for you. Try restoring from a backup to practice. Backups always succeed. It's restores that fail.

Performance is only one of many points we consider when we review tablets, but performance affects your overall impression of the tablet—how zippy and responsive it is when you use apps, navigate the operating system, and surf the Web. On top of that, if your tablet's battery fails to deliver long life, you'll find yourself tethered to an outlet more often than you'd like. Tegra 3 leads the way.

If you build websites for a living, you'll undoubtedly use the obvious web design tools - Firebug, Browsershots, plus the various font embedding services and page speed analysers. So this article isn't about them. Instead we thought we take a look at the more underrated tools that can help you improve client-side browser development and rigorously test everything that you build. Plus 4 alternative tools if these don't quite meet your needs.

Although the design looks remarkably similar, much has changed below the surface. Where each page previously requested at least 14 assets weighing a total of 385kB, now only 9 requests are needed, and with an unprimed cache, these total just over 100kB. I thought it would be interesting to detail the changes I’ve made, and this time, I’ve got graphs! If you watch the bits, the bits watch the bytes.

Because of the low mass, if iPhones and iPads were substituted for larger, NASA-designed computer systems, NASA could save on development time and money (rocket fuel ain’t cheap, you know). Astronauts also get the benefits of an intuitive, well-designed user interface and more modern technology, versus the computers the astronauts now use, which are generally five to 10 years behind the latest consumer tech. This is all about a lot more than simply playing Angry Birds Space in space.

Still have to write the software, and if Apple products are used, then have to use the crappy developement environments Apple is so pleased to provide their developers. At least they should recommend using Windows based products since most of the apps are custom, and Windows has the development environment. Also there are issues with radiation that do not have to be delt with on Earth. I know I have had problems with consumer phones in just a little dampness, and consumer computers and componants also do not do well with water. Would not like to have to depend on them in a life threatening situation.

It looks like some users who have Gmail on their Windows Phone 8 devices are experiencing syncing issues that eventually cause the email app to crash. The problem seems independent of hardware (so 8X and 920 users are affected) and is tied to Gmail specifically. The problem occurs with the People Hub and linked contacts constantly syncing. Likewise, when people head to their Gmail inbox, it too is stuck on a constant sync and may even crash when one attempts to scroll the message list. Optimized for Outlook?

With more than 400 million Firefox users, Mozilla doesn't have a problem with relevance. And with today's disclosure that organization's revenue grew 33 percent to $163.5 million in 2011, the nonprofit organization doesn't have a problem with money. But it does have a problem with mobile. There's an app for that... but it's not Mozilla's app.

Far from ruining your eyes, digital screens can actually help people read better, especially those with bad vision. Researchers from the Robert Wood Johnson Medical School in New Jersey found that people with moderate vision loss could improve their reading speed when reading on a tablet versus on paper. And a backlit screen, such as the iPad's, provided even more benefit than an E Ink screen, as on the original Kindle. Reading comprehension, however, remains a problem.

Since he’s got several Raspberry Pi boards on hand Eric Erfanian decided to see what he could pull off using the robust networking tools present in every Linux installation. His four-part series takes you from loading an image on the SD cards to building a mesh network from RPi boards and WiFi dongles. He says that getting the mesh network up and running is easiest if none of the boards are using an Ethernet connection.... Skynet... Rise of the Raspberry Pi.

Do you keep up on the latest proceedings of the IACR CRYPTO conference? No? Then chances are whenever you have tried to use a cryptographic library you made some sort of catastrophic mistake which would lead to a complete loss of confidentiality of the data you’re trying to keep secret. The most important question is: are you using an authenticated encryption mode? You should.

Working with HTTP from the command-line is a valuable skill for HTTP architects and API designers to have. The cURL library and curl command give you the ability to design a Request, put it on the pipe, and explore the Response. The downside to the power of curl is how much breadth its options cover. Running curl --help spits out 150 different flags and options. This article demonstrates nine basic, real-world applications of curl. I don't always hack on web requests, but when I do, I use the command line.

The biggest change in programming over the last twenty-five years is that today you manipulate a set of useful, flexible data types, and twenty-five years ago you spent a disproportionately high amount of time building those data types yourself. Thinking about how to arrange ready-made building blocks into something new is a more radical change than it may first appear.

In our San Francisco chapter of GirlDevelopIt, we have an increasing number of members that are attending our web development classes because they actually want to get a job in our industry. They come from all sorts of backgrounds... but the important thing to note is that many of them do not come from a computer science background. They are learning web development skills and computer science concepts by attending classes like ours, going through online tutorials like Treehouse or Codecademy, taking online courses like Coursera's CS 101, and generally taking the DIY approach to learning. So, they can do all that to learn the skills that they need for the job, but the question remains, can they actually get a job? What's the best way to show skills and get a job without the degree?

most days you don't need what they teach in school, problem with education is, it's taught (and curriculum as well) by *Academics* with no industry/real world experience
I don't think this is true for everyone but for *many* school is quite irrelevant.
This said, quant finance, CAD/graphics engineering software, gaming ... all uses a lot of linear algebra/matrix mathematics

We’ve become great at curating our lives for the sake of our audiences on various social media services. We post what benefits our reputations, leaving out the parts that reflect poorly on us. Instagram is filled less with interesting photography and more with pictures that makes the photographer look like they lead an interesting life. Foursquare check-ins seem less weighted towards grocery store visits and gas stations and more towards coffee shops, music venues, and other coolhunting hotspots. Facebook is filled with posts that exhibit the wit and witticism of the poster. Pics or it didn't happen.

Did you know... If you listen to CLOUDS.MID backwards, you will go to sleep and have an amazing dream. In it, one by one, you meet the Microsoft Windows 95 Product Team. Finally, you get to Mr. Gates. you reach out to shake his hand, but instead, he puts something in your palm. He smiles. You wake up... Welcome to Windows 95. Here are some features you may not have seen before.

In real life (off the internet), pretty much everyone I meet seems to be using the Raspberry Pi or other Linux embedded system. The use of an actual microcontroller seems quite rare with people I’ve met. Even Arduino seems less popular in my city than embedded Linux. In a way this makes sense — why would someone buy an Arduino when they can get a Raspberry Pi that does so much more at the same price or less? Linux offers a large amount of software out of the box and allows people to program in simpler scripting languages. What is a microcontroller actually good for in comparison to a system on a chip?

Power consumption is a major factor. Many microcontrollers can run on a few µA. Keep in mind that the microcontroller is just the chip, not the board with all the accessories. When designing a purpose-built system you're designing around 100mm² of space, as opposed to 4000mm² or more for all the gadgets.

I've heard many say that Sinofsky is responsible for the death of Silverlight and that it's absence on Windows 8 is a shame. I hear a lot of Silverlight enthusiasts (or apologists) that Silverlight, while being a great technology, was killed because DevDiv and Windows couldn't get along. At last year's build, it was big news that Sinofsky actually said the word Silverlight made news. While the idea that Silverlight ran on a Mac certainly caused waves in the Windows team, it's not the reason for it getting pushed to the pile of technologies that are now in 'sustaining engineering' mode. If any executive is responsible for the current state of Silverlight it's... Steve Jobs.
