Today at Facebook’s press event, Mark Zuckerberg, CEO of Facebook, announced its latest product, called Graph Search.
Zuckerberg made it very clear that this is not web search, but completely different.
He explained the difference between web search and Graph Search. “Web search is designed to take any open-ended query and give
you links that might have answers.” Linking things together based on things that you’re interested in is a “very hard technical problem,”
according to Zuckerberg.
Graph Search is designed to take a precise query and give you an answer, rather than links that might provide the answer.” For
example, you could ask Graph Search “Who are my friends that live in San Francisco?”
Zuckerberg says that Graph Search is in “very early beta.” People, photos, places and interests are the focus for the first iteration of the
product.
Facebook Graph Search is completely personalized. Tom Stocky of the search team explains he gets unique results for a search of
“friends who like Star Wars and Harry Potter.” Then, “If anyone else does this search they get a completely different set of results. ...C...
someone had the same set of friends as me, the results would be different [because we have different relationships with our friends].”
You can also use Graph Search for recruiting. Stocky says if he was looking for people to join the team at Facebook, he could search
for NASA Ames employees who are friends with people at Facebook. “If I wanted to reach out and recruit them, I could see who their friends
are at Facebook. To refine them I can look for people who wrote they are “founders.”
Photos is another big part of Graph Search. Results are sorted by engagement so you see the ones with the most likes and comments
at the top. For example, Lars Rasmussen, Facebook engineer, searched for “photos of my friends taken at National Parks.” He got a gorgeous
page of photos from Yosemite, Machu Pichu, and other parks.

It’s not nice to tell people “I told you so.” But if anybody has the right to say that, it’s Nina E. Olson, the national taxpayer advocate.
Olson recently submitted her annual report to Congress and top on her list of things that need to be fixed is the complexity of the tax
code, which she called the most serious problem facing taxpayers.
Let’s just look at the most recent evidence of complexity run amok. The Internal Revenue Service had to delay the tax-filing season so it
could update forms and its programming to accommodate recent changes made under the American Taxpayer Relief Act. The IRS won’t start
processing individual income tax returns until Jan. 30. Yet one thing remains unchanged − the April 15 tax deadline.
Because of the new tax laws, the IRS also had to release updated income-tax withholding tables for 2013. These replace the tables
issued Dec. 31. Yes, let’s just keep making more work for the agency that is already overburdened. Not to mention the extra work for
employers, who have to use the revised information to correct the amount of Social Security tax withheld in 2013. And they have to make that
correction in order to withhold a larger Social Security tax of 6.2 percent on wages, following the expiration of the payroll tax cut in effect for
2011 and 2012.
Oh, and there was the near miss with the alternative minimum tax that could have delayed the tax filing season to late March. The AMT
was created to target high-income taxpayers who were claiming so many deductions that they owed little or no income tax. Olson and many
others have complained for years that the AMT wasn’t indexed for inflation.
“Many middle- and upper-middle-class taxpayers pay the AMT, while most wealthy taxpayers do not, and thousands of millionaires pay
..A.. income tax at all,” Olson said.
As part of the recent “fiscal cliff” deal, the AMT is now fixed, a move that the IRS was anticipating. It had already decided to program its
systems on the assumption that an AMT patch would be passed, Olson said. Had the agency not taken the risk, the time it would have taken to
update the systems “would have brought about the most chaotic filing season in memory,” she said in her report.
The tax code contains almost 4 million words. Since 2001, there have been about 4,680 changes, or an average of more than one
change a day. What else troubles Olson? Here’s what:
− Nearly 60 percent of taxpayers hire paid preparers, and another 30 percent rely on commercial software to prepare their returns.
− Many taxpayers don’t really know how their taxes are computed and what rate of tax they pay.
− The complex code makes tax fraud ..B.. to detect.
− Because the code is so complicated, it creates an impression that many taxpayers are not paying their fair share. This reduces trust
in the system and perhaps leads some people to cheat. Who wants to be the sucker in this game? So someone might not declare
all of his income, rationalizing that millionaires get to use the convoluted code to greatly reduce their tax liability.
− In fiscal year 2012, the IRS received around 125 million calls. But the agency answered only about two out of three calls from
people trying to reach a live person, and those taxpayers had to wait, on average, about 17 minutes to get through.
“I hope 2013 brings about fundamental tax simplification,” Olson pleaded in her report. She urged Congress to reassess the need for
the tax breaks we know as income exclusions, exemptions, deductions and credits. It’s all these tax advantage breaks that complicate the
code. If done right, and without reducing revenue, tax rates could be substantially lowered in exchange for ending tax breaks, she said.

By Rachel Ehrenberg Science News, Web edition: Monday, February 21st, 2011
WASHINGTON — Getting blood or other perishable supplies to an area that’s been struck by an earthquake or hurricane isn’t as simple as asking what brown can do for you. But a new model quickly determines the best routes and means for delivering humanitarian aid, even in situations where bridges are out or airport tarmacs are clogged with planes.
The research, presented February 18 at the annual meeting of the American Association for the Advancement of Science, could help get supplies to areas which have experienced natural disasters or help prepare for efficient distribution of vaccines when the flu hits.
Efficient supply chains have long been a goal of manufacturers, but transport in fragile networks — where supply, demand and delivery routes may be in extremely rapid flux — requires a different approach, said Anna Nagurney of the University of Massachusetts Amherst, who presented the new work. Rather than considering the shortest path from one place to another to maximize profit, her system aims for the cleanest path at minimum cost, while capturing factors such as the perishability of the product and the uncertainty of supply routes. ‘You don’t know where demand is, so it’s tricky,’ said Nagurney. ‘It’s a multicriteria decision-making problem.’
By calculating the total cost associated with each link in a network, accounting for congestion and incorporating penalties for time and products that are lost, the computer model calculates the best supply chain in situations where standard routes may be disrupted.
‘Mathematical tools are essential to develop formal means to predict, and to respond to, such critical perturbations,’ said Iain Couzin of Princeton University, who uses similar computational tools to study collective animal behavior. ‘This is particularly important where response must be rapid and effective, such as during disaster scenarios … or during epidemics or breaches of national security.
’ The work can be applied to immediate, pressing situations, such as getting blood, food or medication to a disaster site, or to longer-term problems such as determining the best locations for manufacturing flu vaccines. . Retrieved April 7th, 2011.

Worm Infects Millions of Computers Worldwide
By JOHN MARKOFF
A new digital plague has hit the Internet, infecting millions of personal and usiness computers in what seems to be the first step of a multistage attack. The world's eading computer security experts do not yet know who programmed the infection, or what the next stage will be.
In recent weeks a worm, a malicious software program, has swept through corporate, educational and public computer networks around the world. Known as Conficker or Downandup, it is spread by a recently discovered Microsoft Windows vulnerability, by guessing network passwords and by hand-carried consumer gadgets like USB keys.
Experts say it is the
infection since the Slammer worm exploded through the Internet in January 2003, and it may have infected as many as nine million personal computers around the world.Worms like Conficker not only ricochet around the Internet at lightning speed, they harness infected computers into unified systems called botnets, which can then accept programming instructions from their clandestine masters.
Many computer users may not notice that their machines have been infected, and computer security researchers said they were waiting for the instructions to materialize, to determine what impact the botnet will have on PC users. It might operate in the background, using the infected computer to send spam or infect other computers, or it might steal the PC user's personal information.
Microsoft rushed an emergency patch to defend the Windows operating systems against this vulnerability in October, yet the worm has continued to spread even as the level of warnings has grown in recent weeks.
Earlier this week, security researchers at Qualys, a Silicon Valley security firm, estimated that about 30 percent of Windows-based computers attached to the Internet remain vulnerable to infection because they have not been updated with the patch, despite the fact that it was made available in October.
Unraveling the program has been particularly challenging because it comes with encryption mechanisms that hide its internal workings from those seeking to disable it.
The program uses an elaborate shell-game-style technique to permit someone to command it remotely. Each day it generates a new list of 250 domain names. Instructions from any one of these domain names would be obeyed. To control the botnet, an attacker would need only to register a single domain to send instructions to the botnet globally, greatly complicating the task of law enforcement and security companies trying to intervene and block the activation of the botnet.
Several computer security firms said that although Conficker appeared to have been written from scratch, it had parallels to the work of a suspected Eastern European criminal gang that has profited by sending programs known as "scareware" to personal computers that seem to warn users of an infection and ask for credit card numbers to pay for bogus antivirus software that actually further infects their computer.
One intriguing clue left by the malware authors is that the first version of the program checked to see if the computer had a Ukrainian keyboard layout. If it found it had such a keyboard, it would not infect the machine, according to Phillip Porras, a security investigator at SRI International who has disassembled the program to determine how it functioned.
