Hubble telescope reveals huge star’s explosion in blow-by-blow detail.
WASHINGTON: About 11.5 billion years ago, a distant star roughly 530 times larger than our sun died in a cataclysmic explosion that blew its outer layers of gas into the surrounding cosmos, a supernova documented by astronomers in blow-by-blow detail.
Researchers on Wednesday said NASA ’s Hubble Space Telescope managed to capture three separate images spanning a period of eight days starting just hours after the detonation — an achievement even more noteworthy considering how long ago and far away it occurred.
The images were discovered in a review of Hubble observation archival data from 2010, according to astronomer Wenlei Chen, a University of Minnesota postdoctoral researcher and lead author of the study published in the journal Nature.

They offered the first glimpse of a supernova cooling rapidly after the initial explosion in a single set of images and the first in-depth look at a supernova so early in the universe’s history, when it was less than a fifth its current age.
40GBASE-LR4 CWDM and PSM QSFP+ Transceiver Links
There are 40GBASE-SR4 QSFP+ transceivers and 40GBASE-LR4 QSFP+ transceivers. It’s known that 40GBASE-SR4 uses a parallel multimode fiber (MMF) link to achieve 40 G. It offers 4 independent transmit and receive channels, each capable of 10 G operation for an aggregate data rate of 40G over 100 meters of OM3 MMF or 150 meters of OM4 MMF. While for 40GBASE-LR4 QSFP+ transceivers, there are two kinds of links. One is coarse wavelength division multiplexing and the other is parallel single-mode fiber. What’s the difference?

Technology Strikes – “Internet of Things!”
Internet of Things is an evolving topic of practical, communal, and financial importance. Client products, robust goods, transportation, business and utility components, devices, and other everyday objects are being pooled in with Internet connectivity and influential data analytics abilities and aptitudes that guarantee to completely change our every day’s routine. Predictions for the influence of Internet of Things on the Internet and economy are remarkable, with some anticipating more than 101 billion connected Internet of Things devices and a universal financial influence of more than $10 trillion by 2025.
Will 3D Printing Be the Demise of Plastic Injection Molding?
There’s a lot of hype these days about 3D printing. Is this the way all plastic parts will be produced in the future? Will 3D printing overtake the tried-and-true method of plastic injection molding? This article explores the answers to these questions.
Video Streaming Protocols
Video surveillance systems currently are undergoing a transition where more and more traditional analog solutions are being replaced by digital solutions. Compared with an analog video surveillance system, a digital video surveillance offers much better flexibility in video content processing or data transmission. At the same time, it, also, have ability to implement advanced features such as motion detection, facial recognition and object tracking. Applying digital systems, makes the security system capable of transmitting video through the Internet, so we need to study the different methods of video streaming over the network. Streaming is the process of playing a file while it is still downloading. Streaming video is a sequence of “moving images” that are sent in compressed form in a way that it can start being proceed before it is completely received like video clips on a Web page. Here, some of network protocols used in video streaming are described. The focus is on the features of most important protocols in video surveillance including TCP, UDP and RTSP.

Guide on How to Convert PDF to Word
PDF is a convenient, easy-to-use document format. Unfortunately, you can’t use it in editing your document. If you want to edit a document you have to convert the PDF document to Word. The cool thing is that there are many ways in which you can do it. Here are some of the best ways:
NDP – IPv6 Neighbor Discovery Protocol
Neighbor Discovery Protocol is used by IPv6 hosts for a variety of tasks relating to the local area network. In addition, it also works with ICMPv6 to complete a number of operations. The primary tasks for NDP are Router Discovery, Neighbor Discovery and Duplicate Address Discovery. It was devised mainly due to the fact that IPv6 does not allow for broadcasts and therefore ARP (Address Resolution Protocol) as used with IPv4 is not in operation.

Edge Computing Helps in Curtailing Performance Bottlenecks
The utilization of the Internet is greatly trending towards CPU and bandwidth-intensive applications, and several other correlated things. In the meantime, businesses are making every possible effort to converge mobile and data networks into the cloud architecture. CTOs suggest introducing storage capacity and computing capability at the network edge, as it helps in decreasing the time taken by a data packet to travel, and increasing the availability of applications on the network. Herein, edge computing plays a pivotal role in bringing bandwidth-intensive data files and latency-sensitive business applications in proximity to the end-user or data source.
Do You Really Need a Smartwatch?
Although smartwatches have been around since the 80’s, they have received a surge of appeal in the last couple years. One of the biggest reasons smartwatches are increasingly popular these days is perhaps because they are not what they used to be, and are rather getting a lot better than when they were first conceived. When shopping for the smartwatch, you will be spoilt for choice given the vast number of options available, but it’s not really about buying a smartwatch, the big question is do you need one at all.
