Outrageous cuts

18 Feb

PAUL KRUGMAN'S columns tend so often toward scathing criticism of Republicans that it's easy to discount the outrage and dismiss it. It would be a shame if that's the reaction to his writing today, which couldn't be more on point. To wit:

The whole budget debate, then, is a sham. House Republicans, in particular, are literally stealing food from the mouths of babes — nutritional aid to pregnant women and very young children is one of the items on their cutting block — so they can pose, falsely, as deficit hawks.

American government spending has grown across a range of categories—certainly, defence spending has increased as a share of the economy—but the big, looming problem for American solvency is health spending. The Congressional Budget Office's analyses could not be more clear about this. The long-term growth in spending, the stuff that pushes up spending as a share of the economy to unprecedented levels, the stuff that raises deficits and debt as a share of the economy to eye-popping percentages, is in the health portion of the budget. It is, overwhelmingly, Medicare and Medicaid. If members of Congress are unaware of this fact, then they have not picked up a CBO budget analysis, which suggests that they're woefully uninformed on a crucial issue and should not be making any impactful decisions about government outlays.

But of course, legislators are making impactful decisions about government outlays. They're hacking away at non-defence discretionary spending with reckless abandon. A colleague of mine worked up some interesting numbers on non-defence discretionary spending the other day, and I found the data very revealing. Have a look:

Here's a fun fact: non-defence discretionary spending was equal to 3.6% of GDP in 1963. It was also equal to 3.6% of GDP in 2008. It is not behind the increase in government spending as a share of the economy over that time period. It has not made government any less affordable. It is not projected to rise substantially in the future. This is not to suggest that there is no waste in this portion of the government. Without question, there is. This portion of the budget should be subject to close scrutiny, to reform, and perhaps to some cuts (though whether net cuts are justified is far from clear). To pretend that one can balance the budget with cuts focused on this portion of the budget, or that major cuts to this portion of the budget are in any way desirable, is madness. And yet this is what Republicans are doing. Mr Krugman notes that cuts so far have affected programmes that support food budgets of poor Americans. I've pointed out that proposed cuts would reduce spending on job re-training, despite the country's serious long-term unemployment problem. There's more besides:

With tensions rising, House Republicans pushed through a third long night, hoping to win passage late Friday of more than $60 billion in immediate spending cuts that would severely affect agencies in the second half of this fiscal year.

The leadership put the brakes on deep additional cuts, but a school reform program important to President Barack Obama would be decimated by a $336 million reallocation of funds approved by 249-179. The National Endowment of the Arts narrowly lost an additional $22.5 million. And in a blow to the president, Democrats failed to restore $131 million for the Securities and Exchange Commission, facing new responsibilities under Wall Street reforms enacted in the last Congress.

That's right: Democrats were unable to undo cuts to the budget of the commission charged with overseeing behaviour in the financial sector, the responsibilities of which were just overhauled in response to a financial meltdown that very nearly produced an economic depression. And if Republicans are unable to make these cuts law, they're prepared to shut down the government over it.

This is not responsible policymaking. This is not fiscal discipline. This is not a careful, cost-benefit-based analysis of the government's spending priorities. This is a joke. And it's a cruel one.

President Obama isn't out there leading the charge to address long-term fiscal issues in a responsible way, it's true. His budget cuts also focus on non-defence, discretionary spending. The lack of leadership there is disappointing. But his budget doesn't, for the most part, gut valuable programmes in the name of fiscal responsibility. And they absolutely don't excuse this reckless, dangerous behaviour on the part of Congressional Republicans.

 
 

Creating wires between iWidget on Mashup Page

18 Feb
In the Inter iWidget Communication entry i talked about how to create a iWidget that can publish an event as well as create iWidget that can subscribe event. Now i wanted to test this inter iWidget communication inside WebSphere Portal Server. We have two options for using widgets in WebSphere portal, first is we can directly use widgets on the Mashup Page of portal, or we can wrap the widgets in portlet and then add those portlets on a portal page.

I used the steps outlined in http://wpcertification.blogspot.com/2011/02/how-to-register-iwidget-for-use-on.html, to register and add widget on the Portal Mashup page



Then i followed few steps to create the wire between both widgets, these are the screen shots that i took along the way





Once the wires were create i could use them for inter widget communication like this

 
 

The Mystery of the Missing Moon Trees

18 Feb

15 years after NASA astronomer David Williams started searching for them, hundreds of trees grown from space-faring seeds are still missing.

The “moon trees,” whose seeds circled the moon 34 times in Apollo 14 astronaut Stuart Roosa’s pocket, were welcomed back to Earth with great fanfare in 1971. One was planted in Washington Square in Philadelphia as part of the 1975 bicentennial celebrations. Another took root at the White House. Several found homes at state capitals and space-related sites around the country. Then-president Gerald Ford called the trees “living symbol[s] of our spectacular human and scientific achievements.”

And then, mysteriously, everyone seemed to forget about them.

“The careful records weren’t kept, or if they were kept they weren’t maintained,” Williams said. Williams, whose job includes archiving data from the Apollo missions, hadn’t even heard of the moon trees until a third grade teacher e-mailed him in 1996 to ask about a tree at the Camp Koch Girl Scout Camp in Cannelton, Indiana.

“No one around here had ever heard of it,” Williams said. “This is such a neat story, and no one seems to know about it.”

Williams has made it his mission to find them. For the past 15 years, he has kept a record on the web of every known tree’s location. When he started in 1996, he only knew where 22 trees were found. Now, that number has climbed to 80.

But the climb is slow. Mostly, Williams heard of new trees when a hiker or a park visitor found one and e-mailed him about it. The e-mails are ever fewer and farther between, he says.

“It’s been sort of a trickle,” he said. “Most of the easy ones, the low-lying fruit had already been gathered.”

Although most of the trees are long-lived species expected to last centuries, some have started to die off. According to Williams’ most recent tree count, 21 of the 80 known trees are dead, including the Loblolly pine outside the White House, five sycamores and two pines outside the U.S. Space and Rocket Center in Huntsville, Alabama, and one New Orleans pine that was damaged in Hurricane Katrina.

“It’s kind of sad, to see them going,” Williams said.

The trees’ poor health has nothing to do with their journey to space, Williams says.

“No one knew for sure whether being exposed to weightlessness or radiation would do something to the seeds,” he said. “They grew control trees right next to each other to see if they grew differently. But they didn’t find anything.”

The healthy trees have given rise to a crop of half-moon trees, trees grown from the seeds of a moon tree.

“There’s a lot of second generation moon trees being planted now,” Williams said. “That’s getting to the point where I can’t keep up with it.”

You can even buy half-moon seeds online and plant one in your own yard. Williams’ yard hosts a second generation moon tree, a gift from the National Arboretum.

Although Williams will keep looking, there’s no way to know when he’s found them all, he says. But at least the trees won’t be forgotten again.

“At least now there’s a permanent home for it,” he said. “It can’t be lost now. At least all the information that comes in, we have that.”

Update: If you think you’ve found a moon tree, you can contact Williams at dave.williams@nasa.gov. Check the Moon Trees website to see if your tree has been reported before.

IBM Researcher Explains What Makes Watson Tick [VIDEO]

18 Feb


Humanity took a beating from the machines this week. The world’s best Jeopardy player is no longer from the human race.

This week, IBM’s Watson supercomputer defeated Jeopardy‘s greatest champions, and it wasn’t even close. When all was said and done, Watson won $77,147, far more than Brad Rutter ($21,600) or 74-time champion Ken Jennings ($24,000). Its ability to dissect complex human language and return correct responses in a matter of seconds was simply too much for humanity’s best players.

A few years ago though, Watson couldn’t even answer 20% of the questions it was given correctly. And it took hours, not seconds, for Watson to process a question.

At an intimate event in San Francisco, John Prager, one of the researchers developing Watson’s ability to answer complex questions, gave a presentation detailing the work he and his colleagues did to turn Watson into a Jeopardy champion. During his presentation and a Q&A afterwards, Prager and fellow researcher Burn Lewis revealed some key nuggets of information, such as why Watson made those odd, uneven bets during Daily Doubles (an IBM researcher thought it would be boring if Watson’s bets ended with zeros, so he added random dollar amounts for kicks) or which programming languages the researchers used to build Watson (Java and C++).

So what’s next for Watson? Prager says that the next frontier is health care; he hopes that Watson’s technology can help diagnose ailments by analyzing vast quantities of data against patient symptoms and queries.

Check out the video to get a deeper dive into the technology behind Watson. Check it out in HD if you want to read the slides.

Google opens up Public Data Explorer to your data

17 Feb

Public data explorer

With Google's recent data-related offerings, it shouldn't come as much of a surprise that they've opened up their Public Data Explorer so that you can upload your own data. Previously, it was only available when you searched for something like "GDP" and a related dataset was supplied by an official provider.

[W]e’re opening the Public Data Explorer to your data. We’re making a new data format, the Dataset Publishing Language (DSPL), openly available, and providing an interface for anyone to upload their datasets. DSPL is an XML-based format designed from the ground up to support rich, interactive visualizations like those in the Public Data Explorer. The DSPL language and upload interface are available in Google Labs.

In terms of visualization, there's isn't anything new. You've got your maps, bar charts, and time series line charts, with the checkboxes on the left (like the snapshot below). Then there's the chart types available via the charting API.

From what I can tell, the data you upload ends up in the public domain, so it kind of has a Many Eyes feel to it, but less exploratory. Then again, Martin Wattenberg and Fernanda Viegas are now both with Google, so I wonder if this a jumping off point for them to do more. Or maybe they weren't involved at all.

If it's the former, then great, I can't wait to see what comes next. If it's the latter, then the bigger news is that Google packaged a new data format with this release. We'll see how people take to that one.

ImpulsBauhaus

17 Feb

ImpulsBauhaus

As the year marking the 90th anniversary of the establishment of the Bauhaus, 2009 was an appropriate year for an exhibition dedicated to the understanding of the social networks of the Bauhaus movement.

In preparation for this project, biographical details of all of the members of the Bauhaus were systematically structured and entered into an online database. The impressive volume of information resulting from this effort was then presented within an illuminated 4x4meter cube at the Bauhaus University in Weimar.

The exhibition is an immersive yet highly-structured digital archive rich with historical details, where complex interrelationships are made more accessible through the implementation of an innovative graphical interface. All visualizations of the complex network are drawn directly from the research database and presented in an intuitive computer-generated form.

Here is a video on the project.

 
 

600 million-year-old fossils reveal catastrophic oxygen loss on ancient Earth [Evolution]

17 Feb
635 million years ago, almost the entire planet was a frozen ball of ice. And yet mere tens of millions of years later a population explosion happened deep underwater in South China, preceding the better-known Cambrian explosion by a significant time period. In these oxygen-free waters, more than 3,000 fossils of 15 species of seaweeds and worms lived briefly, and then all died suddenly. More »
 
 

Poll Results: HTML5 Features in Use on Production Sites

17 Feb

As a follow up to asking people if they are using HTML5 or not, I asked the people who are:

What features of HTML5 have you used on production sites?

These are the levels of popularity, from almost 3,000 voters:

Not a big surprise that using the new semantic elements (like <nav>) is the most common use of production HTML5. It's easy, it's hip, it feels good.

Right behind that are the new form features. I'm happy to see that, as these things are also very easy to implement and usability tremendously, as well as replace clunky-ish JavaScript methods (I'm thinking of things like range inputs and the placeholder attribute).

Third place is the audio and video features. I'm sure iDevices helped push that along, as using HTML5 is really easy and works on those devices. Fallbacks are now also easy to implement.

The least popular feature is cross document messaging. Also not a huge surprise as it's not all that common of a thing to need. I do think this is super duper cool though, especially as I've been working on a thing that uses it.

"Other" came in ahead of a number of other features, so apparently I've missed a number of HTML5 features that people are actively using. Please share!
