Apple Mac Pro – Complete Redesign of Workstation Desktop

Apple Mac Pro – Complete Redesign of Workstation Desktop

          We have been using desktops for a very long time with the physical design of it remainning the same. There were some innovations made to desktops by companies like Alienware, Razerzone with LEDs to make it look better and attractive. But the overall shape has remained same for years. Have you ever bored of using such design? Here we have Apple’s Mac Pro, a workstation desktop with complete physical redesign.

Mac Pro
          It is upcoming workstation desktop computer from Apple which a complete physical redesign running on Mac.Apple has built such a great performance machine to give better graphics, storage, expansion, processing power, and memory.


Features
  • Dual GPUs
  • PCI Express-based flash storage
  • High-performance Thunderbolt 2
  • new-generation Xeon processors
  • Ultrafast memory
  • support for 4K video

Processor
         Mac Pro is powered by latest Intel Xeon E5 chipset which offers  up to 12 cores of processing power and up to 40GB/s of PCI Express gen 3 bandwidth.

Memory
       Mac Pro includes a four-channel DDR3 memory controller running at 1866MHz. It has a bandwidth capability of 60GB/s.

Graphics
          It offers a very high graphic performance with dual AMD FirePro workstation GPUs with up to 6GB of dedicated VRAM which can support 4K resolution dispalys even for graphic intensive applications

Storage
         We all know about flash storage which offers very high read write performance compared to SATA and other storage technologies. But in Mac pro we have next-generation PCI Express flash storage which is  2.5 times faster than the solid-state drive and up to 10 times faster than a 7200-rpm SATA hard drive.

Expansion Slots
            Mac pro has 6 built‑in Thunderbolt 2 which is the fastest IO technology available, four USB 3, two Gigabit Ethernet ports, and HDMI 1.4 port. each Thunderbolt 2 port has the capability to connect to 6 external peripheral devices and thus with 6 Thunderbolt 2 ports we can use upto 36 external peripheral  devices.


Wireless
         Mac pro comes with built in wireless 802.11ac Wi-Fi for the latest in high-speed wireless connectivity and Bluetooth 4.0.

         We have got a beast which delivers such a great performance with just 9.9″ height and 6.6″ width. Apple has designed a custom thermal solution to drive the heat generated from the CPUs and GPUs.

           Quality product always comes with quality price. But anyway the pricing information and release date is not yet announced.

Virtuix Omni – Advanced Virtual Reality Platform – Includes Natural Movements

Virtuix Omni – Advanced Virtual Reality Platform – Includes Natural Movements

          The digital world has now started moving towards the virtual reality computing. The computer and other digital devices are now very much interactive and has filled the gap between the humans and the electronic devices. there are many virtual reality electronic devices in the line up which includes Oculus Rift, Google Glass, Kinect and many more. Kinect is actually a motion controller for Xbox console which cannot track 3D movements in physical space. Oculus Rift is a VR head-mount display which gives a VR of a very large display with 7inch screen.

 

        Here is another Kickstarter project Omni from Virtuix, a first virtual reality platform for moving freely and naturally in your favorite game. Omni allow us to naturally move with our feet to control movement controls in gaming instead of just sitting and playing with a keyboard, mouse or a controller. This is the next level of futuristic gaming experience.

             The Omni is similar to a treadmill where a user can naturally move around in 360 degrees. It uses a special low friction surface and a special shoes to track the movement of the user. Omni can track movements like walking, running, crouching and strafing. Omni also requires Oculus Rift, VR head-mount to give completely immerse VR experience, a controller and a PC for interfacing all these devices. The project is currently under funding.

Wikipad – Android Gaming Tablet

Wikipad – Android Gaming Tablet

           The gaming industry is taking a great leap with the upcoming release of PS4 and Xbox One. Nvidia has already release its high-end GeForce 700 series GPU. With this lineup we also have handheld gaming console  like Razer Edge which is already in market.Along with these gaming products we also have Wikipad, a android based gaming tablet.

 

           Wikipad is portable gaming tablet which is planned for release later this year for a price of 499 USD. It runs on Android 4.1 (Jelly Bean) operating system. Wikipad is actually a tablet which can be docked into a custom designed controller which makes it a gaming tablet. There are a lot games available for Wikipad from Google Play, PlayStation titles via PlayStation Mobile, and games streamed from Gaikai.

SpaceTop – An Interactive 2D & 3D Computer

SpaceTop – An Interactive 2D & 3D Computer

            SpaceTop is a technology and design to make 2D and 3D spacial interaction in a desktop computer. While a traditional desktop uses a keyboard and a mouse for interaction, SpaceTop uses a completely redefined display setup and visualization for seamless 2D and 3D interaction on the objects on the display. SpaceTop allows users to type, click, draw in 2D, and directly manipulate interface elements that float in the 3D space above the keyboard. SpaceTop uses special hardware which included a depth camera and a transparent display.

 

           The display will look like a transparent thin screen and we will be able to directly interact with the objects on the display screen.Users place their hands behind the screen to manipulate the icons and apps, while a camera tracks their eye position and adjusts the angle, making it appear as though the box is really 3D. There are a lot of researches going on to make the SpaceTop go commercial. The SpaceTop 3D computer is still in the early stages, and no consumer devices are currently planned.

Raspberry Pi – USB Tethering (How to make Internet work in Raspberry Pi by USB Tethering)

How to make Internet work in Raspberry Pi(RPi) by USB Tethering

USB Tethering will not work with initial default configuration of the USB port in RPi. We need to enable the network interface for the USB port to make the internet work with USB tethering. Follow the below steps to  make internet work with USB tethering.


Note: Take backup of the file before you edit

Steps:
1. Boot Raspberry Pi

2. In the start up screen enter the following command to open the file “interfaces”

                   > sudo vi /etc/network/interfaces

sudo will execute the command with administrator privileges

This will open the file “interfaces” in the location /etc/network

3. Add the following line “iface usb0 inet dhcp”  below

auto eth0
iface eth0 inet dhcp

The modified code will look like

auto eth0
iface eth0 inet dhcp
iface usb0 inet dhcp

4. To save the file press the following keys
                      ESC
                        :wq 
                        ENTER

5. Now enter the following command and press ENTER key
                        >sudo ifup usb0

                        Now you will see some auto generated commands on the screen
ifup command will bring a network interface up

6. Reboot Raspberry Pi by executing the command
>sudo reboot

7. Enjoy!!!

Test Configuration:
        RPi : Raspberry Pi ModelB
        RPi OS : Raspbian “wheezy” OS
        Mobile OS : Sony Ericsson Xperia Mini Pro (Android Ice Cream Sandwich)
