Self-sculpting ‘smart sand’ can assume any shape, create instant prototypes (video)

Image

A new algorithm developed by the Distributed Robotics Laboratory at MIT’s Computer Science could lead to an exciting fast prototyping tool, being dubbed “smart sand.” Immerse an object in the sand, tiny cubes that send simple proximity messages to each other, which relay through the swarm and determine which blocks are adjacent to the object to be modeled, and those that aren’t. Using this data, it’s possible to create a map of the subject to be replicated. Initial tests were performed using 2D models, but has also been shown to work reliably with 3D shapes also. While true smart sand would need “grains” much smaller than currently possible, it’s said that this isn’t an “insurmountable obstacle.” The paper will be presented at the IEEE conference in May, or keep going past the break for the explanatory video.

Can social media drive social change? Today, IDEO.org launched HCD Connect, an online community for organizations and individuals, “who are taking a human-centered approach to poverty-related challenges around the world.” The site encourages users who want to leverage the ideas and strategies introduced in the Human Centered Design Toolkit to share stories and resources while learning more about the process.

HCD_Connect_Methods_Page.pngThe Methods page provides a place to learn more about the individual human-centered design methods contained inside the HCD Toolkit.

Designed by IDEO.org with a grant from the Bill & Melinda Gates Foundation, the site offers useful tips for those interested in employing the HCD Toolkit while connecting users to one another. On the site’s landing page, the first thing new users are encouraged to do is to connect with others by location and/or focus areas. Each user can then, in turn, setup a story page so they can share their own work and projects. User story pages include an overview of the project, the location and focus area of the social work (health, gender equity, education etc.) and what methods were employed to support the work. In this way, users can seek out like-minded projects and share resources across borders, “so they can build on each other’s ideas and tap into the power of the community.” In a few months, community members will be able to apply for microgrants to initiate or implement project solutions.

HCD Connect was created as a result of the enthusiasm IDEO and the foundation saw around the HCD Toolkit. IDEO designed the toolkit for organizations and individuals who want to use design methodology to innovate and solve problems in the social sector. The toolkit outlines the step-by-step process IDEO has used over the years. It has been downloaded more than 74,000 times.

IDEO.org is hoping HCD Connect will grow into a vibrant community that supports newcomers to the design process, connects experienced practitioners, and provides support for everyone working to implement HCD methods into their work on social sector challenges.

Watch the beautiful video of how human-centered design has made a difference for Proximity, an aid organization based in Myanmar.

HCD_Connect_Stories_Page.pngThe Stories page is a place for HCD Connect users to post their own stories about how they’ve used the HCD Toolkit or learn about other human-centered design projects.

150 Gigapixel Sky Image Contains 1 Billion Stars

The Bad Astronomer writes “Astronomers have used two big telescopes to create an infrared survey of the Milky Way that is the largest of its kind: the resulting image has an incredible 150,000 megapixels containing over a billion stars. Something that large is difficult to use, so they also made a pan-and-zoom version online which should keep you occupied for quite some time. These data will be used to better understand star formation in our Milky Way, and how far more distant galaxies and quasars behave.”

The interactive image is powered by IIPImage which happens to be Free Software and is cool in its own right (right click the image to get help — it has a full set of keybindings for navigation).

OCZ Vertex 4 SSD released, wins calm praise on the review circuit

OCZ Vertex 4 SSD released, wins calm praise on the review circuit
The Vertex 4 is a big deal for OCZ, because it’s the company’s first top-end SSD to come with an in-house Indilinx controller. We first saw an earlier version of this proprietary silicon put to good effect in the Octane drive a few months ago, and by most accounts the Vertex 4’s updated Everest 2 controller continues in the same vein. The new drive will ship in 128GB, 256GB and 512GB varieties, with MSRPs of $179, $349 and $699 respectively, which stacks up well against Intel’s 520 series. Bearing in mind that only the larger two variants have been sent out for review so far, the general feedback is that the Vertex 4 is reliable and indeed excels in certain key benchmarks like random write performance, which Anandtech described as “incredible.” On the other hand, read performance and some other real-world benchmarks were less earth-shattering, and most reviewers have been quite measured in their conclusions. Storage Review, for example, suggested that the new Vertex’s attractiveness will grow over time, as pricing gets more aggressive and OCZ’s decision to use its own controller pays dividends in terms of support and firmware tweaks. Check out the source links for all the usual benchmark graph goodness.

Dutch Pirateparty Refuses Order To Take Down Proxy


New submitter CAPSLOCK2000 writes “The Dutch Pirateparty has refused an order from BREIN to take down a proxy to The Pirate Bay. Last month BREIN (the distribution-industries paralegal outfit) forced a number of ISPs to block The Pirate Bay; the first site ever blocked in the Netherlands. Immediately people started using proxies at other ISPs to get to TPB. BREIN then threatened a number of those proxies with legal action. As most of these are run by hobbyists without legal or financial means there was little resistance. Now the Dutch Pirateparty has decided to stand up to the intimidation and refuses to take down its proxy. Today they sent there response in style: by uploading it to The Pirate Bay In translation: ‘The Pirateparty disputes your claim and will not comply with your request.'”

Via Torrentfreak, Pirate Party chairman Dirk Poot: “There are a plethora of proxy sites on the internet. On almost any them TPB can by reached, even with a single URL. That’s not even mentioning the ways you can get to TPB if you’re willing to put in more effort than saving a single URL. If this keeps going there will be no Internet left by the time BREIN has achieved its goal of making TPB inaccessible. … In their self-righteous zealousness they have brought substantial damage to the free and open Internet.”

Apps to help you save money

This series is brought to you by
TurboTax Federal Free Edition.

Here’s a roundup of some of my favorite money-saving apps for iOS:

SmartyPig. My favorite money saving app is SmartyPig. It’s designed to let create virtual “piggy banks” for specific savings goals. I have piggy banks for my yearly car insurance bill, for Christmas present money, for my kids’ college funds, and for a new computer every three years.

SmartyPig is linked to your checking account, and every month, a specified amount of money is transferred from your bank account to your piggies. As the pigs get closer to their goal, you can see them getting full. When the goal is reached, you can have the cash transferred to your bank account, or redeem it for a retailer gift card such as Amazon and get a bonus. I seem to have the incurable habit of spending all the readily available money in my checking account, so SmartyPig helps me meet my savings goals.

Debt Free. Last year, I foolishly used credit cards to pay for things I’d ordinarily have used cash to purchase: vacation, back-to-school supplies, school books, clothes for my kids, and business travel. It added up fast. As a result, I am now carrying balances on three different credit cards. The total amount I owe is large enough that I can’t pay it off immediately, so I needed to come up with a plan to get out of debt.

I figured there’d be an app for that, so I looked around the iTunes app store and found something called Debt Free. It’s a well constructed app that helps you use the “Snowball method” to pay down your debt (including credit cards, car loans, lines of credit or any other kind of loan).

If you’re not familiar with the Snowball method, here’s how it works:

1. Make a list of all of your outstanding loan balances, sorted from the lowest balance to the highest balance.

2. Write down the minimum payment for each loan.

3. Figure out how much extra you can afford to pay every month. This is your “snowball.”

4. Pay the minimum payment on each loan, and apply the snowball to the loan with the lowest balance.

5. When the lowest balance loan gets paid off, start applying the extra payment to the next lowest loan on your list.

6. Repeat steps 1-5 until you are free of debt.

Debt Free automates the above process. You simply enter information about each card (remaining balance, interest rate, due date and minimum payment) and how much of a snowball you can afford. It crunches the numbers, generates a payment schedule and tells you when you will be debt-free. It will also notify you when a bill is due (even if the app is not running), and send you a detailed report by email.

Mint. I’ve been a user of Mint, a personal finance website, for several years, and it has become an essential tool for keeping track of my expenses and organizing information that my accountant needs to prepare my income taxes. The great thing about Mint is the way it pulls data from my checking account, savings accounts, stock brokerages, and credit cards and creates attractive and easy to understand reports and graphs. It’s so much easier to use than Quicken, which I struggled with for over 15 years. As soon as I started using Mint, I zapped Quicken from my hard drive, vowing never to use it again. (I got nervous when I learned that Intuit, the company that publishes Quicken, purchased Mint, but so far Intuit has not mucked with the elegance of Mint.)

Shortly after the iPhone was introduced, Mint created an app for it. And like the Web version, the iPhone app was very useful at providing a snapshot of my income, expenses, and financial status. I didn’t think Mint could get much better, but in October the company created an iPad version (which is free, like all versions of Mint) and it is the best way yet to take stock of your personal finances.
When you launch the iPad app you are presented with a screen that displays the following:

1. A pie chart that shows your spending by category;

2. Alerts about upcoming bills and other important information;

3. A progress bar that shows how much under or over budget you are for the month;

4. A list of your top spending categories for the month.

If you click on any of these items, Mint will drill down to display detailed information about it. If you need to edit a transaction, or change the spending category that Mint has incorrectly assigned to a transaction, you can do that on the iPad app, but I find it easier to make those kinds of changes on the web-based version.

If you haven’t tried out Mint yet, I highly recommend that you do. And if you have an iPad, I’m betting you’ll find the Mint app to be as useful as I do.


note: Mint is owned by Intuit, sponsors of this content series. Intuit had no input into or review of the content of this post.

Microsoft ships SQL Server 2012, refreshes Hadoop on Azure preview



On April 2, Microsoft released SQL Server 2012, the latest version of its SQL Server database platform. The company also announced the availability of a second preview for the company’s Hadoop “big data” service for the Windows Azure cloud.

Many of SQL Server 2012’s new features serve the high end of Microsoft’s customer base. They focus on supporting hybrid IT environments that blend more traditional data center deployments with those in private and public cloud computing environments. These features include SQL Server Data Tools, a new common set of tools for SQL Server and cloud SQL Azure application and database development. The release also contains the Power View web-based ad-hoc data visualization tool, which allows users to generate presentations and reports by pulling data from published SQL Server datasets and other data sources published through Microsoft’s Windows Azure Marketplace.

The new Hadoop preview ups the capacity and reliability of the trial service on Azure. According to a blog post from Microsoft’s SQL Server team, Microsoft has quadrupled the capacity of the preview from its initial invitation-only trial. The company also added disaster recovery features for the Hadoop Distributed File System in the Azure cloud. The new preview includes the promised data connections for Office and SharePoint. There is also support for connections from SQL Server 2012’s Power View and other business analytics tools—as well as support for open-source Hadoop analytics projects such as Mahout. Microsoft customers can sign up for a slot in the Hadoop on Azure trial at hadooponazure.com.

US Army grants HP $249 million contract to deploy private cloud services

Image

HP is in the Army now. Today, the Palo Alto company announced that it has received a $249 million contract to provide the Department of Defense and other federal agencies with enterprise level cloud computing services. The new initiative will allow the military to consolidate its existing data centers, and the services will be deployed to a number of commercial and government-owned buildings. HP will also provide the military with Performance-Optimized Data Centers (PODs) for quick deployment into tactical situations. Under the terms of the Army Private Cloud contract, HP will work with ten small businesses and Alabama A&M University to help actualize the private cloud and its requirements. We can only assume that Meg Whitman is glad to start out the month with a bit of walking-around money. You’ll find the full PR after the break.

Apple holds the master decryption key when it comes to iCloud security, privacy



Ars recently attempted to delve into the inner workings of the security built into Apple’s iCloud service. Though we came away reasonably certain that iCloud uses industry best practices that Apple claims it uses to protect data and privacy, we warned that your information isn’t entirely protected from prying eyes. At the heart of the issue is the fact that Apple can, at any time, review the data synced with iCloud, and under certain circumstances might share that information with legal authorities.

We consulted several sources to understand the implications of iCloud’s security and encryption model, and to understand what types of best practices could maximize the security and privacy of user data stored in increasingly popular cloud services like iCloud. In short, Apple is taking measures to prevent access to user data from unauthorized third parties or hackers. However, iCloud isn’t recommended for the more stringent security requirements of enterprise users, or those paranoid about their data being accessed by authorities.
