DDR4 memory reaches the home PC market

DDR4 is the fourth generation of double data rate, synchronous dynamic random-access memory (SDRAM) after DDR (2002), DDR2 (2004) and DDR3 (2007).* It features greater speed, memory density and energy efficiency, with devices using 20 nanometre (nm) process technology allowing consumer-grade modules of up to 32 GB.* Though Samsung and others introduced DDR4 memory boards in 2013, processor boards like Intel's Broadwell did not yet support this standard. High-end servers in data centres were able to take advantage of DDR4 in 2014. However, the home PC market would have to wait until 2015.*

Windows 9 is released by Microsoft

Following the much-criticised Windows 8, Microsoft launches a major overhaul of the operating system in 2015. Windows 9.0 addresses a number of usability issues – refining the "Metro" design language of its predecessor and providing a more distinct experience for desktop, mobile and other platforms. This includes a return of the traditional Start Menu. The OS introduces a more unified code base, for improved compatibility and simpler transfer of data between various devices and services. There is a much greater focus on apps. Highly advanced gesture recognition is also incorporated, now that 3D cameras are becoming more common. It also deals with power management issues. Initially codenamed "Threshold", it is released in April 2015.**

 

2015 Upcoming Technology

Virtual reality makes a comeback

Exponential improvements in processing power (doubling every 18 months) are enabling the creation of highly lifelike graphics and 3D environments. At the same time, faster broadband is opening up new frontiers in cyberspace, allowing the development of Web 3.0 – the next generation of Internet. This is being combined with developments in on-person hardware, creating renewed interest in virtual reality.* Having been something of a gimmick in the 1980s, it is now becoming a serious tool for business, leisure, education and training.
Much of the content in these 3D environments is user-generated, with online communities for sharing and exchanging virtual objects, buildings, avatars, etc. Among the popular hardware configurations to emerge is a circular treadmill-like interface, allowing players to move freely and naturally in all directions.*

Increased automation in retail environments

Checkout operators of retail chains are increasingly being replaced with automated systems, in order to save costs and improve efficiency. The customer simply scans the items themselves, and is prompted via on-screen instructions and audio to insert their method of payment. In 2009, around 100,000 self-service checkouts were installed worldwide. By 2014, this number has more than quadrupled.*
 

Most phone calls are made via the Internet now

By now, the majority of homes and workplaces use Voice over Internet Protocol (VoIP) systems, such as Skype.* These connections are made via the Internet, rather than traditional phone lines. The biggest advantage of VoIP is the cost. PC-to-PC phone calls can be made anywhere in the world, at any time, for free. PC-to-phone connections usually charge a fee, but are generally much cheaper than standard phone services with conventional handsets.
Another advantage is the portability. Phone calls can be made and received from any PC – provided there is a broadband connection – simply by signing into a personal VoIP account. Phone-to-phone VoIP is also portable. When you sign up with a VoIP servicer provider, the Internet phone or adaptor that is used with that service is assigned a unique number. This 'phone number' remains valid even if your VoIP service provider is located in England and you are connected to the Internet in Australia. An Internet phone is small and light enough to take with you anywhere. It can simply be plugged into any broadband connection, anywhere in the world, and used to make and receive calls, just as though you were in your own home or office.
There are several other features that make VoIP attractive. Higher fidelity (wideband) audio, video, call forwarding, call waiting, voicemail, caller ID and multiple-way calling at no extra charge. Digital data such as pictures, documents and other files can also be transmitted during calls.

India's first Mars mission

Joining the MAVEN probe this year is another orbiter, the first Indian mission to Mars.* Launched in November 2013, the probe enters a highly elliptical orbit of 500 x 80,000 km around Mars in September 2014. The payload of 25 kg consists of ten instruments – including a colour camera, infrared and thermal analysers, a radiation spectrometer, methane sensor, and a Plasma and Current Experiment. Controversy surrounds the mission, however, in light of foreign aid to alleviate the country's ongoing poverty and social problems.*

The first test flight of NASA's Orion spacecraft

The Orion Crew Exploration Vehicle was originally part of NASA's Constellation Program which was cancelled in 2010. However, the design was carried forward as the Orion Multi-Purpose Crew Vehicle (Orion MPCV), as part of NASA's new plans for manned exploration to the Moon, Mars and asteroids.
The first test flight is in 2014.* For this particular mission, the capsule is unmanned. Nevertheless, it reaches a higher altitude than any spacecraft intended for human use since 1973. Orion makes two highly elliptical orbits of the Earth, before re-entering the atmosphere and splashing down in the Pacific Ocean.
This test supports the development of the Space Launch System – a new dedicated rocket, which itself will be tested in 2017. The first manned flight of Orion will occur in the 2020s, depending on Nasa's future funding.*

Completion of the International Space Station

The International Space Station is by far the largest man-made structure ever put into orbit: 110m (360 ft) across, with a mass of 345,000 kg and a living volume of 1,000 cubic metres. It is maintained in a nearly circular orbit with a minimum mean altitude of 330 km (205 mi) and a maximum of 410 km (255 mi). It travels at an average speed of 27,724 kilometres (17,227 mi) per hour, completing 15 orbits per day. Primary fields of research on board the vessel include human research, space medicine, life sciences, physical sciences, astronomy and meteorology. The station had been scheduled for completion in 2012. However, installation of the final two components, the Russian multipurpose laboratory module Nauka and the European Robotic Arm were delayed. Once built, the ISS remains in operation until 2028.
 

Smart watches are the latest must-have gadget

Worldwide, the market for smart watches has grown from 500,000 in 2013, to over 5 million by the end of 2014. These devices – which function as wearable computers – are the most important new product category in consumer electronics since the iPad.
Apple, Google, Microsoft and Samsung are among the firms launching a variety of stylish, hi-tech watches, incorporating a myriad of new hardware and software features to boost their appeal to consumers. Among the most popular uses are in health and wellness monitoring, sports and fitness. The market for traditional watches is being disrupted by the added functionality of this new generation.*

Google Glass is launched to the public

Google Glass is an augmented reality head-mounted display, allowing hands-free access to the web.* The product resembles normal eyeglasses where the lens is replaced by a small electronic screen. It provides interaction via natural language voice commands, as well as eye-tracking technology.* A miniature gyroscope can tell the user's position and orientation at all times. On the side frame is audio output, and a touch control pad, while on top is a button for recording photos and videos with a built-in camera. It is available to developers by 2013 and for the general public by 2014.* The design allows for integration of the display into people's day-to-day eyewear. It is light and weighs less than most sunglasses. A prototype unveiled in 2012 received criticism over the potential for Google to insert advertising (its main source of revenue) into the user's field of vision. However, the company denied it would use adverts.

The Internet has a greater reach than television

Citizens in developed nations now rely on the Internet more than any other medium for news coverage. This trend* first became apparent in the early 2000s, when radio was overtaken by Internet usage. The rapid shift towards web-based information then began to affect print media, with newspaper sales being heavily impacted.
By 2014, the trend has continued, with even television now having less reach when it comes to news reporting. Television and the Internet are in fact converging together as one. Social media, mobile technologies and exponential bandwidth improvements have driven much of this change.
 

A Football That Broadcasts Where It Is On The Field

How to Track a Football

In this photo, researchers taped ball-tracking components to the outside of a football to show what the components look like. In gameplay, the transmitter and antenna are tucked inside the ball.

David Ricketts

A team of engineers has built a prototype tracker for a different kind of football than what's in the news right now. The tracker overcomes one major difference between American football and soccer—the fact that in football, sometimes you have a half-dozen big guys pile on top of the ball.
Goal-line technology, like what the World Cup uses, relies on cameras set up around the field to watch where the ball goes. The cameras don't exactly have X-ray vision, however, so they're a no-go for pileups. On the other hand, with the new prototype tracker, "you can actually have all 22 people jump on top of the football," says David Ricketts, an engineering professor at North Carolina State University who worked on developing the system. "You can see right through the players and see the football directly."
Ricketts and his colleagues' system includes hardware that sends out signals from inside ball itself. Sensors arranged around the field then triangulate the ball's position from the signals they pick up.
It's not a new idea to have a ball broadcast its position on the field. Ricketts and his team tried to bring the idea closer to reality by using a type of signal that's safe, yet unobstructed by human bodies. Players' bodies would interfere with GPS and RFID signals, Ricketts tells Popular Science. So the engineering team, including researchers from Carnegie Mellon University and Disney Research, decided to try something called magnetoquasistatic fields. (Disney is interested because it owns ESPN, who wanted to see if this is feasible, Ricketts says.)

"You can actually have all 22 people jump on top of the football. You can see right through the players and see the football directly."

The football's emitting components create a magnetic field that moves very slowly, which is why it's called quasi—or seemingly—static. The slight movement helps sensors detect the field, and thus locate the ball.
One major challenge to using magnetoquasistatic fields is that when they contact the ground, they're absorbed and re-emitted, creating unwanted signals the sensors pick up. Ricketts and his team wrote an algorithm to remove the effect of Earth from the signals their sensors read.
The North Carolina State University team has played with Ricketts' and his colleagues' system. Still, the system needs some improvements before it's feasible for real games. It needs to be more accurate. For now, it can track a ball on a football field within about two feet of its actual location. For the system to be useful to umpires and game-watchers, it needs to be accurate within about half a football's length. Teams might also want the emitting device in the football to be smaller and lighter. These kinds of improvements will need to wait for a commercial lab, however.
Meanwhile, Ricketts' academic team plans to continue to research magnetic fields for tracking objects. Besides ball tracking, Ricketts imagines other uses for this technology. It could track people's gestures for games, devices, or giving feedback to athletes. It could also help companies keep tabs on boxes and inventory.

Invention Awards 2014: A Powerful, Portable, And Affordable Robotic Exoskeleton

Titan Arm

Surviving a stroke or debilitating injury is often the start of a very long ordeal. Physical therapy can be slow and strenuous with no guarantee of recovery. Robotic exoskeletons can sometimes provide the support a ravaged body needs to heal—and strength when it can’t—but they typically cost more than a car and must be anchored to a wall and plugged into a socket.In late 2012, a team of mechanical engineering students at University of Pennsylvania set out to build a portable, affordable exoskeleton. Two semesters of late nights and long weekends later, Elizabeth Beattie, Nicholas McGill, Nick Parrotta, and Nikolay Vladimirov had the Titan Arm: an efficient, lightweight, and surprisingly powerful robotic limb. Its actuator, or electronic muscle, could provide resistance during therapeutic exercises and can augment strength, allowing its wearer to lift an additional 40 pounds with little effort.
To ensure a slimmer frame than other exoskeletons and make Titan Arm easier for patients to use, the team situated its actuator in a backpack instead of in the limb itself. They also milled load-bearing parts out of aluminum to limit weight and power consumption. McGill, the electronics lead, created a software-and-sensor package to track arm movements and wirelessly relay the data. This would allow a patient to use a Titan Arm at home and a therapist to remotely monitor the exercises.
Potential beneficiaries, including stroke victims and an injured snowboarder, have already reached out to the team with encouraging comments. The positive response to their $2,000 prototype has made Titan Arm’s makers eager to push their invention toward a finished product and, to that end, they are now designing a more refined version. “We’ve been looking at 3-D printing to fully customize components, like tailoring a suit,” says Parrotta. 

1) POWER:

Lithium-polymer battery packs provide a day’s worth of power.

2) MUSCLE:

An electric motor in the backpack winds steel cables to rotate pulleys and induce arm movement. Beattie (left) designed a support system to safely distribute weight across a hip belt, elbow straps, and back plate.

3) BRAINS:

Software reads the positions of magnetic sensors in the steel joints to instruct movement, which the operator controls from a handheld device.

A portable retina scanner small enough to fit in a purse could one day be used to combat identity theft and strengthen personal security.
The new device is about 5 inches (12 centimeters) long and 3.5 inches (9 cm) wide, making it more compact than traditional stationary retinal scanners.
"Based on our research, this device is unique with respect to its compactness," Uwe Schelinski, a researcher at the Fraunhofer Institute for Photonic Microsystems in Dresden, Germany.

Memory Layout of C Programs

Memory Layout of C Programs

A typical memory representation of C program consists of following sections.
1. Text segment
2. Initialized data segment
3. Uninitialized data segment
4. Stack
5. Heap

A typical memory layout of a running process
1. Text Segment:
A text segment , also known as a code segment or simply as text, is one of the sections of a program in an object file or in memory, which contains executable instructions.
As a memory region, a text segment may be placed below the heap or stack in order to prevent heaps and stack overflows from overwriting it.
Usually, the text segment is sharable so that only a single copy needs to be in memory for frequently executed programs, such as text editors, the C compiler, the shells, and so on. Also, the text segment is often read-only, to prevent a program from accidentally modifying its instructions.
2. Initialized Data Segment:
Initialized data segment, usually called simply the Data Segment. A data segment is a portion of virtual address space of a program, which contains the global variables and static variables that are initialized by the programmer.
Note that, data segment is not read-only, since the values of the variables can be altered at run time.
This segment can be further classified into initialized read-only area and initialized read-write area.
For instance the global string defined by char s[] = “hello world” in C and a C statement like int debug=1 outside the main (i.e. global) would be stored in initialized read-write area. And a global C statement like const char* string = “hello world” makes the string literal “hello world” to be stored in initialized read-only area and the character pointer variable string in initialized read-write area.
Ex: static int i = 10 will be stored in data segment and global int i = 10 will also be stored in data segment
3. Uninitialized Data Segment:
Uninitialized data segment, often called the “bss” segment, named after an ancient assembler operator that stood for “block started by symbol.” Data in this segment is initialized by the kernel to arithmetic 0 before the program starts executing
uninitialized data starts at the end of the data segment and contains all global variables and static variables that are initialized to zero or do not have explicit initialization in source code.
For instance a variable declared static int i; would be contained in the BSS segment.
For instance a global variable declared int j; would be contained in the BSS segment.
4. Stack:
The stack area traditionally adjoined the heap area and grew the opposite direction; when the stack pointer met the heap pointer, free memory was exhausted. (With modern large address spaces and virtual memory techniques they may be placed almost anywhere, but they still typically grow opposite directions.)
The stack area contains the program stack, a LIFO structure, typically located in the higher parts of memory. On the standard PC x86 computer architecture it grows toward address zero; on some other architectures it grows the opposite direction. A “stack pointer” register tracks the top of the stack; it is adjusted each time a value is “pushed” onto the stack. The set of values pushed for one function call is termed a “stack frame”; A stack frame consists at minimum of a return address.
Stack, where automatic variables are stored, along with information that is saved each time a function is called. Each time a function is called, the address of where to return to and certain information about the caller’s environment, such as some of the machine registers, are saved on the stack. The newly called function then allocates room on the stack for its automatic and temporary variables. This is how recursive functions in C can work. Each time a recursive function calls itself, a new stack frame is used, so one set of variables doesn’t interfere with the variables from another instance of the function.
5. Heap:
Heap is the segment where dynamic memory allocation usually takes place.
The heap area begins at the end of the BSS segment and grows to larger addresses from there.The Heap area is managed by malloc, realloc, and free, which may use the brk and sbrk system calls to adjust its size (note that the use of brk/sbrk and a single “heap area” is not required to fulfill the contract of malloc/realloc/free; they may also be implemented using mmap to reserve potentially non-contiguous regions of virtual memory into the process’ virtual address space). The Heap area is shared by all shared libraries and dynamically loaded modules in a process.
Examples.
The size(1) command reports the sizes (in bytes) of the text, data, and bss segments. ( for more details please refer man page of size(1) )
1. Check the following simple C program

#include <stdio.h>   int main(void) {     return 0; }

[narendra@CentOS]$ gcc memory-layout.c -o memory-layout
[narendra@CentOS]$ size memory-layout
text       data        bss        dec        hex    filename
960        248          8       1216        4c0    memory-layout

2. Let us add one global variable in program, now check the size of bss (highlighted in red color).

#include <stdio.h>   int global; /* Uninitialized variable stored in bss*/   int main(void) {     return 0; }

[narendra@CentOS]$ gcc memory-layout.c -o memory-layout
[narendra@CentOS]$ size memory-layout
text       data        bss        dec        hex    filename
 960        248         12       1220        4c4    memory-layout

3. Let us add one static variable which is also stored in bss.

#include <stdio.h>   int global; /* Uninitialized variable stored in bss*/   int main(void) {     static int i; /* Uninitialized static variable stored in bss */     return 0; }

[narendra@CentOS]$ gcc memory-layout.c -o memory-layout
[narendra@CentOS]$ size memory-layout
text       data        bss        dec        hex    filename
 960        248         16       1224        4c8    memory-layout

4. Let us initialize the static variable which will then be stored in Data Segment (DS)

#include <stdio.h>   int global; /* Uninitialized variable stored in bss*/   int main(void) {     static int i = 100; /* Initialized static variable stored in DS*/     return 0; }

[narendra@CentOS]$ gcc memory-layout.c -o memory-layout
[narendra@CentOS]$ size memory-layout
text       data        bss        dec        hex    filename
960         252         12       1224        4c8    memory-layout

5. Let us initialize the global variable which will then be stored in Data Segment (DS)

#include <stdio.h>   int global = 10; /* initialized global variable stored in DS*/   int main(void) {     static int i = 100; /* Initialized static variable stored in DS*/     return 0; }

[narendra@CentOS]$ gcc memory-layout.c -o memory-layout
[narendra@CentOS]$ size memory-layout
text       data        bss        dec        hex    filename
960         256          8       1224        4c8    memory-layout
