A Quick Look at Amazon's AWS Services


In 2006, Amazon Web Services (AWS) began offering IT infrastructure services to businesses in the form of web services -- now commonly known as cloud computing. One of the key benefits of cloud computingis the opportunity to replace up-front capital infrastructure expenses with low variable costs that scale with your business. With the Cloud, businesses no longer need to plan for and procure servers and other IT infrastructure weeks or months in advance. Instead, they can instantly spin up hundreds or thousands of servers in minutes and deliver results faster.
Today, Amazon Web Services provides a highly reliable, scalable, low-cost infrastructure platform in the cloud that powers hundreds of thousands of businesses in 190 countries around the world. With data center locations in the U.S., Europe, Brazil, Singapore, Japan, and Australia, customers across all industries are taking advantage of the

The R Project for Statistical Computing


R Graphics Demo

The R Project for Statistical Computing

R is a language and environment for statistical computing and graphics. It is a GNU project which is similar to the S language and environment which was developed at Bell Laboratories (formerly AT&T, now Lucent Technologies) by John Chambers and colleagues. R can be considered as a different implementation of S. There are some important differences, but much code written for S runs unaltered under R.
R provides a wide variety of statistical (linear and nonlinear modelling, classical statistical tests, time-series analysis, classification, clustering, ...) and graphical techniques, and is highly extensible. The S language is often the vehicle of choice for research in statistical methodology, and R provides an Open Source route to participation in that activity.
One of R's strengths is the ease with which well-designed publication-quality plots can be produced, including mathematical symbols and formulae where needed. Great care has been taken over the defaults for the minor design choices in graphics, but the user retains full control.
R is available as Free Software under the terms of the Free Software Foundation's GNU General Public License in source code form. It compiles and runs on a wide variety of UNIX platforms and similar systems (including FreeBSD and Linux), Windows and MacOS.

The R environment

R is an integrated suite of software facilities for data manipulation, calculation and graphical display. It includes
  • an effective data handling and storage facility,
  • a suite of operators for calculations on arrays, in particular matrices,
  • a large, coherent, integrated collection of intermediate tools for data analysis,
  • graphical facilities for data analysis and display either on-screen or on hardcopy, and
  • a well-developed, simple and effective programming language which includes conditionals, loops, user-defined recursive functions and input and output facilities.
The term "environment" is intended to characterize it as a fully planned and coherent system, rather than an incremental accretion of very specific and inflexible tools, as is frequently the case with other data analysis software.
R, like S, is designed around a true computer language, and it allows users to add additional functionality by defining new functions. Much of the system is itself written in the R dialect of S, which makes it easy for users to follow the algorithmic choices made. For computationally-intensive tasks, C, C++ and Fortran code can be linked and called at run time. Advanced users can write C code to manipulate R objects directly.
Many users think of R as a statistics system. We prefer to think of it of an environment within which statistical techniques are implemented. R can be extended (easily) viapackages. There are about eight packages supplied with the R distribution and many more are available through the CRAN family of Internet sites covering a very wide range of modern statistics.
R has its own LaTeX-like documentation format, which is used to supply comprehensive documentation, both on-line in a number of formats and in hardcopy. Learn more about (R)...

After Spirit and Opportunity, Curiosity is ready to Go!


Spirit and Opportunity, Curiosity is powered with radioisotope thermal generators, and is thus not limited by the availability of solar power. However, it will still need to reduce activity during the coldest winter months, when more of its power will be required to keep its instruments warm. It also carries a more sophisticated analytical instrument package than Spirit and Opportunity. Curiosity will assess past habitability by searching for and identifying organic compounds, possible metabolic products of ancient organisms, and studying the rocks for details about the past climate in which they formed. Curiosity carries ten science instruments. What makes the science instrument suite of Curiosity unique are the analytical tools located within the body of the rover, which will perform detailed chemical analyses of about 70 samples of rock and soil delivered to them by the robotic arm. Sample Analysis at Mars (SAM) includes a gas chromatograph, mass spectrometer, and tunable laser spectrometer, and is intended to identify organic compounds and also to measure the isotopic ratios of chemical elements important to life. CheMin is an X-ray diffraction X-ray fluorescence instrument, which directly measures the bulk elemental composition of rocks and soils, allowing scientists to infer mineral composition. read more (planetary.org)

Geiger Counter Kit



Introducing the Geiger Counter Kit from the Maker Shed. This kit costs a fraction of a commercial unit and it works just like you it should, blinking and clicking in the presence of radiation. It takes about an hour to build and even has a serial output for tracking radioactivity over time.
Is Grandma’s pottery or glass collection radioactive? Do bananas give off radiation? Is that granite table given to you by your mother-in-law slightly “hot?” (In my case, yes!) With this Geiger Counter Kit these questions are yours to answer. While this is a functional Geiger counter it is for educational purposes only. Please do not use it for anything important.

Nesting PC Virtual Tablet' Concept

 
'nesting pc virtual tablet' by sono mocci


a concept by japanese-born, italy-based designer sono mocci, 'nesting pc virtual tablet' is a combination tablet and data visualization 
interface with automatic battery charging and data syncing. phones, memory cards, CDs, USB ports, and I/O cables can be plugged 
directly into the device, where they will show up as images on the touchscreen for easy manipulation and access. the design was shortlisted 
from over 1000 concepts in our recent designboom competition 'a life with future computing', organized in collaboration with FUJITSU.

the 13-inch concept tablet features a dedicated dock for mobile phones. when inserted, a visualization of the phone onscreen 
works in the same manner as would the device itself, permitting dialing, calling, texting, and other use. the loading of disk media 
or flash drives offers a similar intuitive functionality. integrated charging eliminates the need for AC or outlet-specific adapters 
for these kinds of devices.

Google Plus



Visit https://plus.google.com/



A quick look at the first pieces of the project.


Sharing is a huge part of the web, a part that we think could be a lot simpler. That's why we've been working on adding a few new things to Google: To make connecting with people on the web more like connecting with them in the real world. We hope that you like what we've cooked up so far. And stay tuned, because there's more to come.


Circles


You share different things with different people. But sharing the right things with the right people shouldn't be a hassle. Circles makes it easy to put your friends from Saturday night in one circle, your parents in another and your boss in a circle all on his own – just like in real life.

Sparks


Remember when your Grandpa used to cut articles out of the paper and send them to you? That was nice. That's kind of what Sparks does: It looks for videos and articles that it thinks you'll like, so that when you're free there's always something to watch, read and share. Grandpa would approve.

Hangouts


Bumping into friends while you're out and about is one of the best parts of going out and about. With Hangouts, the unplanned meet-up comes to the web for the first time. Let your mates know that you're hanging out and see who drops by for a face-to-face-to-face chat. Until we perfect teleportation, it's the next best thing.

Knocking down barriers to knowledge - Google Search by Image and Voice

As much as technology has advanced, there are still many barriers between you and the answers you’re looking for—whether you’re juggling a clunky mobile keyboard or waiting for a website to load. Today we held a media event in San Francisco where we talked about some of the latest things we’re doing to tackle these barriers on mobile, announced that we’re bringing our speech recognition and computer vision technology to the desktop, and took the next step for Google Instant—Instant Pages.


The thirst for knowledge doesn’t stop when you step away from your computer, it continues on your mobile device. In the past two years, mobile search traffic has grown five-fold. Mobile search today is growing at a comparable pace to Google in the early years.


Here you can see that mobile search traffic growth over the past three years (the red line) is comparable to overall Google search traffic growth over the same duration (the blue line) but earlier in our history.

One of the technologies driving this growth is speech recognition. With Voice Search, you don’t have to type on a tiny touchscreen. You can just speak your query and the answer is on the way. We’ve invested tremendous energy into improving the quality of our recognition technology—for example, today we teach our English Voice Search system using 230 billion words from real queries so that we can accurately recognize the phrases people are likely to say. As the quality has increased, so has usage: in the past year alone, Voice Search traffic has grown six-fold, and every single day people speak more than two years worth of voice to our system.

We first offered speech recognition on mobile search, but you should have that power no matter where you are. You should never have to stop and ask yourself, “Can I speak for this?”—it should be ubiquitous and intuitive. So we've added speech recognition into search on desktop for Chrome users. If you’re using Chrome, you’ll start to see a little microphone in every Google search box. Simply click the microphone, and you can speak your search. This can be particularly useful for hard-to-spell searches like [bolognese sauce] or complex searches like [translate to spanish where can I buy a hamburger]. Voice Search on desktop is rolling out now on google.com in English, but in the meantime you can check it out in our video:



Searching with speech recognition started first on mobile, and so did searching with computer vision. Google Goggles has enabled you to search by snapping a photo on your mobile phone since 2009, and today we’re introducing Search by Image on desktop. Next to the microphone on images.google.com, you’ll also see a little camera for the new Search by Image feature. If you click the camera, you can upload any picture or plug in an image URL from the web and ask Google to figure out what it is. Try it out when digging through old vacation photos and trying to identify landmarks—the search [mountain path] probably isn’t going to tell you where you were, but computer vision may just do the trick. Search by Image is rolling out now globally in 40 languages. We’re also releasing Chrome and Firefox extensions that enable you to search any image on the web by right-clicking.



Whether you type, speak or upload a photo, once you’ve indicated what you’re looking for the next step in your search is to sift through the results and pick one. To make this faster, last year we introduced Google Instant, which gives you search results while you type. We estimated Google Instant saves you between two and five seconds on typical searches. But once you’ve picked a result, you click, and then wait again for the page to load—for an average of about five seconds.

We want to help you save some of that time as well, so today we took the next step for Google Instant: Instant Pages. Instant Pages can get the top search result ready in the background while you’re choosing which link to click, saving you yet another two to five seconds on typical searches. Let’s say you’re searching for information about the Smithsonian Folklife Festival, so you search for [dc folklife festival]. As you scan the results deciding which one to choose, Google is already prerendering the top search result for you. That way when you click, the page loads instantly.



Instant Pages will prerender results when we’re confident you’re going to click them. The good news is that we’ve been working for years to develop our relevance technology, and we can fairly accurately predict when to prerender. To use Instant Pages, you’ll want to get our next beta release of Chrome, which includes prerendering (for the adventurous, you can try Instant Pages today with the developer version). It’s one more step towards an even faster web.

To learn more about today’s news, visit our new Inside Search website atwww.google.com/insidesearch. There you’ll find a recording of the event (when it’s ready), answers to common questions and links to other blog posts about today’s news on the Mobile blog and Inside Search blog. The Inside Search website is our new one-stop shop for Google search tips, games, features and an under-the-hood look at our technology, so there’s plenty for you to explore.

We’re far from the dream of truly instantaneous access to knowledge, but we’re on our way to help you realize that dream.
