YouTube Flips Switch on 360° Videos As we inch closer to a world in which virtual reality is no longer science fiction, YouTube is taking the early lead as the destination of choice for 360-degree videos made specifically for VR headgear. Parent company Google on Friday flipped the switch on 360-degree video uploading but don't get excited just yet.

This list will no doubt swell as more cameras hit the market. Assuming you have the right camera, it’s still not as simple as just upload a video like normal. Uploaders will need to include certain metadata for 360-degree playback which can either be enabled by running a YouTubecreated app or through a Python script. Details for both methods can be found by clicking here.

Google offers up a few tips to get the most out of your 360-degree camera. For starters, you’ll want to encode video at a high resolution. YouTube currently supports 360 degree videos with 24, 25 or 30 frames per second with plans to add higher frame rates soon.

While it’s cool to see YouTube jumping onboard the 360degree bandwagon early, don’t expect much in terms of quality right now as it being compared to that of a 2004 flip phone. Remember those? When viewing these videos you can use the mouse to pan around on a desktop or laptop but only with Chrome.

Another restriction you’ll find is that only four cameras – Giroptic 360cam, IC Real Tech Allie, Kodak SP360 and Ricoh Theta – are compatible with YouTube as of today.

Toggle Android 5.0 device settings with your voice. Forget third-party widgets, Google's Search app will now let you use your voice to toggle several settings on Android Lollipop devices . A recent update to the Google Search app on Android 5.0 Lollipop devices will allow users to toggle their Wi-Fi, Bluetooth and flashlight (camera LED) with their voice. The device will also need to be running the most recent version of the Google Search app for these voice commands to work. To test them, you can tap the search button in the app, or wake the service with the "OK, Google" command, if you have that set up. Next, simply ask the service to toggle your Wi-Fi, Bluetooth or the flashlight. For example: "OK, Google, turn on Bluetooth." A Google Now card appears and shows you what's being toggled. You

can touch the card to adjust the toggle if you asked for the wrong one or changed your mind. Additionally, if you have the volume on, you'll hear confirmation of the action being spoken to you. Right now this feature only works for Wi-Fi, Bluetooth and the flashlight. However, it will still bring up shortcuts to your other settings -- like GPS, NFC and Airplane mode -- if you ask it to toggle them.

4 Tips & Tricks Every Android User Needs to Know by Ben Stegner Android is an awesome mobile operating system, but feeling lost while using it is completely understandable. Below are some tips and tricks that will give you even more control over your device. Let’s begin!  Control Your Default Apps and Notifications

When you open a link on Android, if you have multiple apps that can handle it, you’ll have to choose which one you’d like to use. This pop-up includes two choices: Just Once and Always. Choosing the former means you’ll be asked next time you try to open a similar link, while the latter sets that app as default for those kind of links. If you always open a particular link with the same app, it makes sense to just set it as the default.

Should you need to clear that app due to a mistake, just head to Settings > Apps > [App Name] and choose Clear Defaults to reset your choice. While you’re in settings, you can also clear the Show Notifications box if you’d prefer not to be notified by an app at all.  Make Changes to Your Apps on the Play Store

Google Play is the place to get all kinds of apps for your Android. You might however be irritated by some of the behaviors it exhibit. So here’s how to fix them. First, you might notice that apps automatically update without you having to explicitly tell them to. Since keeping everything up to date keeps you safe, it’s wise to leave this enabled so your apps don’t become horribly outdated. However, some may be concerned about these updates using their data plan or otherwise object to the practice. If you want to take on the responsibility for updates, open the Play Store on your phone and tap the slide-out menu in the top left, followed by Settings. In this menu, you can turn auto updates off completely, enable them on WiFi only, or let them run at any time. The WiFi option is probably the wisest choice, but it’s up to you.  Turn Off Autocorrect

Autocorrect is essential on most Android devices, as typing on a tiny keyboard doesn’t lend itself well to accuracy. The best keyboards all implement autocorrect with varying degrees of success, but sometimes you don’t want your phone to assume it knows what you mean. For those times when you’re just jotting down notes or practicing your typing accuracy, you can easily turn off auto-correction.  Take a Screenshot

Screenshots are extremely useful for illustrating an issue you’re having or for capturing a funny moment, perhaps in a text message or on Facebook. Thankfully, in recent versions of Android, the action for taking a screenshot has been simplified. Just push Power + Volume Down (might not work for older android devices) at any time to take a picture of what’s on the screen. It will be saved to your Gallery; from there you can send it to a friend or post it online. Source: http://www.makeuseof.com/tag/4-tips-tricks-every-android-user-needs-know/

Accelerating the Web By SICARII13 As web users, an important aspect of web surfing, other than UI, is page load time. No user likes to sit before their screen watching the loading indicator for a few seconds after typing a URL. From a designer/developer stand-point, slow page load times affects a website’s search engine ranking. To address this matter and improve content delivery, web acceleration is used. Web Acceleration is the process of speeding up the transfer of content between a Web server and a client browser. Web accelerators can be a self-contained hardware appliance or installable software and may be installed on the client (browsing) computer or mobile device, on ISP servers, on the server computer/ network, or a combination.

In order for high traffic sites to support hundreds, and at times thousands, of users and to scale to meet high volumes, modern computing best practices require adding more servers to handle more requests. Continuously adding web servers can become an expensive endeavor. Web Acceleration uses various methods to speed delivery of both static and dynamic content enabling Web servers to handle more client requests without the need for more hardware. Web accelerators may use several techniques to achieve a reduction in access time which includes: HTTP Optimization: One of the

primary ways to accelerate Web traffic is by using a Load Balancer or Reverse Proxy server to optimize HTTP traffic as it flows between clients and back-end servers. Through HTTP optimization techniques, the Load Balancer sits in between clients and servers accepting requests for Web content and sending them to the server pool in a streamlined and efficient manner that maximizes speed and server utilization. Caching and pre-fetching: Web Acceleration servers can cache or locally store commonly requested information so that additional time and effort is not wasted to fetch that content over and over from back-end Web servers, resulting in overall content acceleration. If the Web content changes from time to time then the Web Accelerator can refresh it’s cache at a specified interval. Compression: A Web Accelerator can compress large documents that are being passed back and forth such as images to speed up transfer times. SSL Processing: Some advanced Web Accelerators can offload additional processing to free up back-end Web server resources such as encrypting and decrypting documents during secure SSL transmissions.

A Look at 3D Printing : Could this be the manifestation of the 2nd Digital Revolution? Imagine a future in which a device connected to a computer can print a solid object. A future in which we can have tangible goods as well as intangible services delivered to our desktops or high-street shops over the Internet. And a future in which the everyday "atomization" of virtual objects into hard reality has turned the mass pre-production and stockholding of a wide range of goods and spare parts into no more than an historical legacy. Such a future may sound like it is being plucked from the worlds of Star Trek. However, while transporter devices that can instantaneously deliver us to remote locations may remain a fantasy, 3D printers capable of outputting physical objects have been in both development and application for over three decades, and are now starting to present a whole host of new digital manufacturing capabilities. 3D printing may therefore soon do for manufacturing what computers and the Internet have already done for the creation, processing and storage of information. Such a possibility has also started to capture mainstream media attention. The Economist, for example, has now published several articles on 3D printing, including The Printed World (February 2011), and most recently the superb 3D Printing Scales Up (September 2013). Whether or not they arrive en-masse in the home, 3D printers have many promising areas of potential future application. They may, for example, be used to output spare parts for all manner of products, and which could not possibly be stocked as part of the inventory of even the best physical store. Hence, rather than throwing away a broken item (something unlikely to be justified a decade or two hence due to resource depletion and enforced recycling), faulty goods will be able to be taken to a local facility that

will call up the appropriate spare parts online and simply print them out. 3D printers may also be used to make future buildings. To this end, a team at Loughborough University is working on a 3D concrete printing project that could allow large building components to be 3D printed on-site to any design, and with improved thermal properties. Another possible future application is in the use of 3D printers to create replacement organs for the human body. This is known as bio printing, and is an area of rapid development. In an age in which the news, books, music, video and even our communities are all the subjects of digital dematerialization, the development and application of 3D printing reminds us that human beings have both a physical and a psychological need to keep at least one foot in the real world. 3D printing has a bright future, not least in rapid prototyping (where its impact is already highly significant), but also in the manufacture of many kinds of plastic and metal objects, in medicine, in the arts, and in outer space. Desktop 3D printers for the home are already a reality, and should cost no more than a few hundred dollars by 2015. 3D printers capable of outputting in colour and multiple materials also exist and will continue to improve to a point where functional products will be able to be output. As devices that will provide a solid bridge between cyberspace and the physical world -- and as an important manifestation of the Second Digital Revolution, 3D printing is therefore likely to play some part in all of our futures.

Thoughts On The New MacBook

by Dylan Tweney

When Apple announced its new MacBook last week, I was initially excited. A Retina display — with resolution of 2,304 by 1,440 pixels — and a hugely promising 9 hours of battery life with active Web use sounded like exactly what I wanted. Plus, it weighs only slightly more than an iPad, at just 2 pounds. A nicer keyboard and a “force touch” trackpad are nifty add-ons, if not anything anyone had actually asked for.

drawback. If, like many laptop users, you like to plug in your laptop while connecting it to an external monitor, you’ll be out of luck with the MacBook. It will force you to choose between recharging and connecting to a monitor. And if you want to connect to a monitor, you’ll need to buy a $79 adapter cable. clear that the MacBook is suffering from two serious flaws.

One, that processor! It’s a 1.1GHz or 1.2GHz Intel Core M processor, Even the USB-C port that others aka the “Broadwell” line of chips. have complained about didn’t Apple and other PC makers, not to bother me.

In short, this is a $1,300 netbook, more comparable to Google’s latest Chromebook Pixel than anything else. Cult of Mac writes that the MacBook is a down payment on the future of laptops. Other PC makers may mock the MacBook today, but in a year or two, Apple will address some of the more glaring flaws (maybe adding a second USB-C port), drop the price, and mop up the competition. It followed this playbook with the initial MacBook Air, which was ridiculously overpriced and limited when it first came out, but which is an affordable workhorse today. If Apple is indeed moving towards a more tablet-centric future, I have a suggestion: Make that Retina screen into a touchscreen, and make the keyboard detachable. But if you did that, you’d have something a lot like Microsoft’s Surface Pro 3, wouldn’t you?
