Laser gun is deployed and operational on U.S. Navy warship

By
After several years of research and testing, the U.S. Navy has introduced a new laser gun designed to protect ships without using ammunition.   Another entry on our  timeline  is now a reality as the U.S. Navy has authorised the first operational use of a laser weapon. This new hi-tech system – known as the Laser Weapon System (LaWS) – is designed to serve as a form of defence against drones and other small flying vehicles or small-boat enemies including suicide attackers. It is highly accurate, able to hit objects moving at up to 300 mph (480 km/h). The LaWS fires a solid-state infrared beam with two modes: high output to destroy a target, and low output for optical "dazzling", warning shots or to cripple a potential attacker. Among the advantages of this device versus projectile weapons is the low cost per shot, as each firing of the weapon requires only minimal cost for generating the energetic pulse; by contrast ordnance for projectile weapons must be des...

Intel announces the first 14 nanometre processor

By
At the Computex conference in Taipei, chipmaker Intel has revealed a fanless mobile PC reference design using the first of its next-generation 14nm "Broadwell" processors. The 2 in 1 pictured here is a 12.5" screen that is just 7.2 mm thick with keyboard detached and weighs 670 grams.  The Surface Pro 3  – for comparison – is 9.1 mm thick and weighs 800 grams. It includes a media dock that provides additional cooling for a burst of performance. The next-generation chip is purpose-built for 2 in 1s and will hit the market later in  2014 . Called the Intel Core M, it will be the most energy-efficient Intel Core processor in the company's history with power usage cut by up to 45 percent, resulting in 60 percent less heat. The majority of designs based on this new chip are expected to be fanless, with up to  32 hours of battery life,  offering both a lightning-fast tablet and razor-thin laptop. Intel is also delivering innovation and performance for the ...

How to prevent Recent and Phone Favorite contacts from showing in your iOS task switcher

By
When you double-click your iPhone's home button, you will be greeted with the task switching screen, which presents you with card deck-style snapshots of your active apps to freely browse and switch to. With iOS 8, however, where most iPhones are at the moment, Apple introduced a Favorites row there, with circular pictures of your most recently used contacts. Most people aren't bothered by their recent contacts appearing there, but for some this means easy snooping on who they've called or texted last, or simply unnecessary clutter. If you don't want to wait until  iOS 9  hits and gets rid of these circular shenanigans in your task switcher, here's what you need to do to get rid of them: 1. Go to the Settings app, and scroll down to the Mail, Contacts, Calendars section; 2. From Mail, Contacts, Calendars, look for the Contacts section, which will be hosting the Show in App Switcher options; 3. Tap on Show in App Switche...

How to Choose BitLocker Drive Encryption Method and Cipher Strength in Windows 10?

By
BitLocker is an encryption method that enables users to lock the different drives in  Windows . The drives which are protected by BitLocker are accessed by passwords. Windows has provided opportunity for users to choose and configure the  cipher  strength and algorithm used by BitLocker Drive Encryption. This can be achieved via the Local Group Policy editor. The Local Policy Editor will let you configure and select the cipher method for BitLocker encryption. By default it is not configured but you can choose your choiceable encryption method by enabling the Policy Setting. If the drive is already encrypted or if encryption is in progress, the encyption method will have no effect. If you leave the policy unconfigured, then BitLocker will use the default encryption method of AES 128-bit with Diffuser or the encryption method specified by the setup script. Steps to Choose BitLocker Drive Encryption Method and Cipher Strength in Windows 10 1.  ...

Oculus’ New $99 Samsung Gear VR Makes Serious Virtual Reality Affordable

By
At half the price of its last mobile VR headset, the new $99  Oculus-made  Samsung Gear VR is cheap enough to unlock virtual reality for the mainstream. Revealed today at the Oculus Connect conference, it works with the whole 2015 line of Samsung Smartphones including the Note 5, S6, S6 Edge, and S6 Edge+. It will ship in November in time for Black Friday. Compared to the $199 previous Gear VRs that only worked with fewer phones, this headset will be a lot more accessible. The new Gear VR is 22% lighter, making it more comfortable to wear. The trackpad on the temple of the headset also now has a tactile directional pad on it so your finger will know where it’s touching. The previous Gear VRs had a smooth trackpad and sometimes it was to tough to know if you were touching it or just the unsensitive shell of the headset when you couldn’t see for yourself. There’s also a new Gear VR Gamepad which all the Oculus Connect conference attendees will get for free. It features an...
