With protests, Egyptians mark uprising anniversary
CAIRO (AP) ? Two years after Egypt's revolution began, the country's schism was on display Friday as the mainly liberal and secular opposition held rallies saying the goals of the pro-democracy uprising have not been met and denouncing Islamist President Mohammed Morsi.
With the anniversary, Egypt is definitively in the new phase of its upheaval.
From the revolt that began Jan. 25, 2011 and led to the fall of autocrat Hosni Mubarak, the country has moved into a deeply divisive struggle between ruling Islamists, who say a string of election victories the past year gives them to right to reshape Egypt, and their opponents, who say Islamists are moving to take complete power.
Overshadowing their struggle is an economy in free-fall that threatens to fuel public discontent. The vital tourism sector has slumped, investment shriveled, foreign currency reserves have tumbled and prices are on the rise. More pain is likely in the coming months if the government implements unpopular new austerity measures.
"Today the Egyptian people continue their revolution," said Hamdeen Sabahi, a leading opposition leader who finished a close third in presidential elections held in June. "They are saying 'no' to the Brotherhood state ... We want a democratic constitution, social justice, to bring back the rights of the martyrs and guarantees for fair elections."
Tens of thousands massed in Cairo's Tahrir Square, where the 2011 uprising began, and outside Morsi's palace, with more heading to join them from other districts. Banners outside the palace proclaimed, "No to the corrupt Muslim Brotherhood government" and "Two years since the revolution, where is social justice?" Others demonstrated outside the state TV and radio building overlooking the Nile.
Similar if smaller crowds gathered in most of Egypt's main cities, including the Mediterranean cities of Alexandria. The protesters chanted the iconic slogans of the revolt against Mubarak, this time directed against Morsi ? "Erhal! Erhal!" or "leave, leave" and "the people want to topple the regime."
Clashes erupted in multiple places between police firing tear gas and protesters throwing stones ? in side streets around Tahrir, in Alexandria and the city of Suez and in six other cities. Outside the gates of the presidential palace in Cairo, masked protesters tried to push through a police barricade, prompting a barrage of tear gas by security forces.
In two towns in the Nile Delta, Menouf and Shibeen el-Koum, protesters blocked railway lines, disrupting train services to and from Cairo.
At least 119 people were injured in the clashes around the country, the head of the national ambulances services, Mohammed Sultan, told privately owned CBC TV. He did not give details on the nature or location of the injuries.
The immediate goal of the protesters is a show of strength to push Morsi to amend the constitution, which was pushed through by his Islamist allies and rushed through a national referendum. But more broadly, protesters are trying to show the extent of public anger against what they call the rule of the Muslim Brotherhood, the organization Morsi hails from, which they say is taking over the state rather than setting up a broad-based democracy.
Protester Ehab Menyawi said he felt no personal animosity against the Brotherhood but opposed its approach toward Morsi as Egypt's first freely elected leader.
"The Brotherhood thinks that reform was achieved when their man came to power and that in itself is a guarantee for the end of corruption," he said as he marched from the upscale Cairo district of Mohandiseen to Tahrir with some 20,000 others.
Unlike in 2012, when both sides made a show of marking Jan. 25 ? though, granted, not together ? the Brotherhood stayed off the streets for Friday's anniversary. The group said it would honor the occasion with acts of public service, like treating the sick and planting trees. The Brotherhood's ultraconservative allies known as Salafis are also staying off the streets. Their absence may reduce, but not entirely remove, the possibility of violence.
The night before, Morsi gave a televised speech that showed the extent of the estrangement between the two sides. He denounced what he called a "counter-revolution" that is "being led by remnants of ousted president Hosni Mubarak's regime to obstruct everything in the country."
Brotherhood officials have increasingly depicted the opposition as undemocratic, trying to use the streets to overturn an elected leadership.
In another sign of the increasingly bitter tone, new militia-like groups opposed to the Islamists have declared in video messages posted on social networks this week their intention to defend the opposition protesters if attacked. At least 10 people were killed and hundreds injured in December when Morsi's supporters descended upon protesters camped outside his palace, starting clashes that lasted for hours with firebombs, swords, knifes and firearms.
The demands of Friday's protesters vary. Some on the extremist fringe of Egypt's loosely knit opposition want Morsi to step down and the constitution adopted last month rescinded. Others are calling for the document to be amended and early presidential elections held.
"I am asking everyone to go out and demonstrate to show that the revolution must be completed and that the revolution must continue," opposition leader Mohamed ElBaradei said in a televised message posted on his party's website.
"There must be a constitution for all Egyptians. A constitution that every one of us sees himself in it," said the Nobel peace Laureate and former head of the U.N. nuclear watchdog.
Egypt's bestselling novelist and democracy campaigner Alaa al-Aswany marched with ElBaradei on Friday to Tahrir. "It is impossible to impose a constitution on Egyptians, a constitution which was sponsored by the Supreme guide of the Muslim Brotherhood, and the revolution today will bring this constitution down," he said.
Morsi, a U.S.-trained engineer, took office in June after a narrow election victory with just under 52 percent of the vote to become the country's first freely elected president.
On the horizon are key elections to choose a new lower house of parliament. The opposition is hoping it can leverage public anger into a substantial bloc in the legislature, but it is still trying to weld together an effective campaign coalition in the face of Islamists' strength at the ballot box.
Last winter, the Brotherhood and Salafis won around 75 percent of the lower house's seats, though the body was later disbanded by court order.
Opponents say Morsi and his Islamist backers have taken that election mandate too far, accusing the secretive, closed Muslim Brotherhood of simply stepping in to fill the shoes of Mubarak's ousted ruling party, only now with a conservative religious bent.
The most glaring example is the constitution itself: Islamists finalized the draft in a rushed, all-night meeting, throwing in amendments to fit their needs, then pushed it through a swift referendum in which only a third of voters participated. The result is a document that could bring a much stricter implementation of Shariah, or Islamic law, than modern Egypt has ever seen.
At the same time, Morsi has kept government policy-making and the choice of appointments almost entirely within the Brotherhood. Members and supporters of the group are being installed bit by bit throughout the state infrastructure ? from governor posts, to chiefs of state TV and newspapers, down to preachers in state-run mosques.
"Egypt is in a bad place, It's been wholly consumed with issues of power, and governance has been left by the wayside. None of this had to be," said Michael W. Hanna, a senior fellow at the New York-based Century Foundation. "It was a conscious decision to eschew reform by consensus. ... For them (the Brotherhood) it's not about reform it's about power."
In Egypt, the danger for the Brotherhood now is that it stands alone as it faces the difficult task of stopping the accelerating slide of the economy. That will require some highly unpopular decisions, including raising taxes and reducing subsidies on fuel and basic foodstuffs. Morsi's government has so far not put forward a cohesive plan, and public anger is growing over mounting prices, unemployment and poverty.
If Morsi and the Brotherhood can't fix the economy, they may try to keep the support of their Islamist base by focusing instead on "the culture war," pushing through a religious agenda of stricter Shariah and more sectarian rhetoric against Egypt's Christian minority, warns Hanna.
"We'll see more polarized politics, and that's a bad omen for actually governing," he said.

Essentially Angela talks Modern Love: What's the formula for success?
I?ve been thinking quite a bit about relationships this week?
What is it that keeps some going strong while others start promising, only to end tragically?
We all know the couple whose break up shocked us, and we also know the marriage that is still going strong despite everyone?s assumptions that it would end before the five-year Wood Anniversary.
So what gives? How is it that some people make it and others don?t??
It would be easy to give the standard answer and say it?s all about love. ?You either have it or your don?t.
But I disagree. ?LOVE has good intentions. I?ve seen people who love each other but can?t make it work.
Studying healthy relationships, toxic ones, and yes, even experimenting with the concept myself, I?ve realized there are five key elements that lasting partnerships must have.
?
1. Respect.?
If you don?t respect the person you lie down next at night, it won?t last. ?Respect. For their ideas, their dreams, their goals.?Respect for how they conduct themselves in life, and respect for the kind of person they are. ?The moment you feel disdain for your partner is the beginning of the end. ?It might take a long time to get there, but believe me, if you don?t have respect it?s a sure indicator you are on the road to break up.
2.?Healthy Disagreement.?
You will argue, that?s a given. ?You won?t agree sometimes on things- like politics, where to go to dinner, or how to discipline your children. ?But the way you handle yourself during these disagreements is telling to your relationship. ?Fighting fair is a must for strong relationships. ?So is talking it out. ?Remember what your grandparents told you about never going to bed angry? It?s true. ?Even if it means you hash it out all night, that?s what you do. ?Get to the bottom of things. ?If you don?t, resentment starts building its wall, layer upon layer until one day, one of you forgets to load the dishwasher and the other packs bags and is out the door for good.
3. Emotional & Physical Connection. ?
Sex has to be a priority. Cuddling has to be a priority. Romance can not die. The moment you let these fall to the back burner, is the moment you are short-changing your relationship. ?As much as we love our success, family, hobbies, ourselves?if you don?t constantly work on your relationship with your partner and put them as the most important thing in your life, YOU WILL FAIL.?
Success feels amazing but it doesn?t keep you warm at night, children grow up and find their own partners, hobbies and narcissistic pursuits are great at the time, but eventually it just gets empty. If we all worked as hard on our relationship as we did every other area in our lives, the divorce rate would be much lower?and we would all be much happier.
4. Support For Each Other.?
We all need someone to have our back. ?Someone to support us no matter if we have victories on a great scale or fail epically. Knowing that a partner supports everything we do is key for all of the above: Respect, Healthy Disagreement, and Connection.
When you commit to a partnership, you commit to support. No matter the cause.
5. The Three F?s.?
FEED him. FUCK him. Make him FEEL like a man.?
I?ve taken a lot of shit for this one belief more than any other over the years. Despite dissenter?s arguments (always women) I firmly believe that in the confines of the relationship:?A?man is the man and the woman is the woman.?
This has nothing to do with income or status. ?Don?t tell me this is the 21st century and my thinking is old school and puts women?s lib back 100 years.
This has everything to do with EVOLUTION. Men need to be taken care of, have their sexual needs met, and know they are in charge of their domain.
Try to manipulate this by emasculating?your man, withholding sex, or always being in control and eventually your man will turn from you, in one way or another. ?Emotionally or physically you will lose him, many times to someone who will provide exactly what you would not.
?
Whether you are in a relationship currently or in pursuit of one, reminding yourself of the 5 elements above on a regular basis will ensure that your partnerships remain healthy and strong forever. ?Despite the escalating divorce rate and fear of commitment, everyone walking this earth would be completely satisfied with one?forever if done properly.
Do you have the commitment it takes to honor FOREVER??

Time Spent In Retailers? Mobile Apps Grows More Than Five-Fold In A Year, Flurry Finds
Consumers spent six times as much time in retailer apps in December compared to a year earlier, showing that shopping and commerce is finally beginning to take off on mobile platforms. Flurry, the mobile analytics startup, looked at about 1,800 iOS and Android apps from December 2011 to December of last year. They also broke it down into five other categories including Retailer Apps, Price Comparison, Purchase Assistant, Online Marketplace and Daily Deals. Time spent in apps overall grew by 132 percent year-over-year, so as you can see above, basically every category except for daily deals outpaced growth in the rest of the ecosystem. Retailer apps like ones directly from Walmart, Target, Macy’s, Victoria’s Secret, Gap and Saks 5th Avenue, grew the most in terms of time spent. Time spent in ‘Price Comparison’ apps like eBay’s RedLaser and Grocery IQ grew by 247 percent year over year. At the same time, “Purchase Assistant” apps like ShopSavvy and ShopAdvisor saw 228 percent more time spent. Even though Daily Deals apps like Groupon, which have spent millions on user acquisition, have seen their market share fall, they still saw the time spent metric at least double. Groupon has said in the past that one-third of its revenues come from mobile purchases in North America. But you can see how market share has changed for mobile commerce apps. Daily deals apps, which were very early to mobile platforms and could spend millions upon millions to acquire users every year, were first-movers. Now the rest of the space is catching up as big box retailers figure out how to use mobile apps to promote transactions. Retailers nearly doubled their market share in the shopping category, with 27 percent of time spent up from 15 percent a year ago. Virtually every other category was either flat or down year-over-year in terms of market share. Marketplace apps like eBay and Amazon fell to 20 percent marketshare from 25 percent a year ago, while price comparison and purchase assistant apps were basically flat year-on-year.Source: http://feedproxy.google.com/~r/Techcrunch/~3/-f7s25QFQKo/

AP Source: Obama picks Mary Jo White to lead SEC
WASHINGTON (AP) ? President Barack Obama will nominate Mary Jo White to lead the Securities and Exchange Commission, tapping an attorney with broad experience in prosecuting white-collar crimes to lead an agency that has a central role in implementing Wall Street reform.
A White House official said the president would announce White's nomination during a ceremony in the State Dining Room Thursday afternoon.
At the same event, Obama will renominate Richard Cordray to serve as head of the Consumer Financial Protection Bureau, the official said. The president used a recess appointment last year to circumvent Congress and install Cordray as head of the bureau. That appointment expires at the end of this year.
The official spoke on the condition of anonymity in order to discuss the nominations ahead of the president.
White spent nearly a decade as the U.S. attorney in Manhattan, building a reputation as a tough prosecutor with an expertise in pursuing white collar crimes and complex securities and financial fraud cases. White House officials say that experience makes her well positioned to implement Obama's Wall Street reform legislation.
While serving as U.S. attorney, White also won convictions related to the 1998 bombings of two U.S. embassies in Africa and the 1993 World Trade Center bombing.
If confirmed by the Senate, White would take over the helm at the SEC from Elisse Walter, who is serving out the rest of former SEC chair Mary Schapiro's term. Schapiro resigned in December.
Cordray has run the consumer bureau since last year, when Obama used a recess appointment to install him in the job. Senate Republicans had opposed Cordray, as well as the concept of the consumer bureau.
Sen. Elizabeth Warren, D-Mass., first conceived of the idea of a consumer protection bureau. Obama considered naming her to lead the bureau, but her nomination would likely have run into deep opposition on Capitol Hill.
White, 65, currently heads the litigation department at law firm Debevoise & Plimpton.
She was the first woman to hold the position of U.S. attorney in Manhattan, one of the most prestigious positions in federal law enforcement. During her tenure from 1993 to 2002, White won convictions of white-collar criminals, drug traffickers and international terrorists. The most notable was Ramzi Yousef, the mastermind of the 1993 World Trade Center bombing.
She also led the prosecution of mob boss John Gotti when she was acting U.S. attorney in Brooklyn in 1992. Gotti died in prison in 2002.
If confirmed by the Senate, White would be the first prosecutor to head the 79-year-old SEC. Most SEC chairmen traditionally have come from Wall Street or the ranks of private securities lawyers. The choice of White is likely intended to bolster the agency's enforcement profile in the aftermath of the financial crisis.
White's background differs sharply from Schapiro, who stepped down last month after guiding the agency in the four years after the crisis. Schapiro worked at the Commodity Futures Trading Commission and the Financial Industry Regulatory Authority, the securities industry's self-policing organization. Some consumer advocates have said that Schapiro's experience as CEO of FINRA made her more likely to seek compromises and less likely to aggressively pursue misconduct.
During Shapiro's tenure, the SEC reached major settlements with the biggest banks on Wall Street, including Goldman Sachs, JPMorgan Chase and Citibank. But critics said the penalties were small compared with the banks' revenues. And they complained that no senior executives were held accountable.
White would be expected to give high priority to expanding the enforcement efforts.
At the same time, much of the pressing work facing the agency involves writing new rules. The SEC is seeking stricter rules for money-market mutual funds and must get into shape the so-called Volcker Rule, which would bar banks from making certain trades for their own profit.
As head of the litigators at Debevoise & Plimpton, White has represented a number of financial institutions likely to have crossed swords with the SEC in enforcement cases. Her clients also included former Bank of America CEO Ken Lewis, whom she represented in a 2010 civil lawsuit by then-New York Attorney General Andrew Cuomo accusing Lewis of misleading shareholders in the bank's merger with Merrill Lynch.
White also represented the largest U.S. hospital chain, HCA, in the insider-trading investigations by the SEC and the Justice Department of former Senate Majority Leader Bill Frist, whose family owned HCA. The investigations were closed in 2007 with no charges filed against Frist.

Guns at Home: Where a Shooting Range Is Part ... - AOL Real Estate
We've been talking about guns in America over the last week, and we know that the debate over gun control can get very heated. But let's leave aside for a moment the question of whether gun permits in a neighborhood help or hurt property values and instead take a look at the real estate itself. Here are properties that both pro- and anti-gun forces might at least agree are impressive (or intimidating). Thanks to our friends at Estately for tipping us off to this smokin' real estate!
Newtown Square, Penn.
This $16.95 million home has a basement shooting range. Thanks to the unique requirements and building permits necessary to build an indoor shooting range, you won't happen upon these homes very often. But if you're hell-bent on blowing off some steam during television commercials, maybe it's worth it.
Rutledge, Ga.
If all the red tape is stopping you from building a shooting range in your own home, then building one outside your home is probably the next best thing. See this $925,000 home in Rutledge, for example. All you need is some wide open space for a professional-looking rifle range with bullet-stops and target-holders.
Mitchells, Va.
If shotguns are more your thing, then this $149,000 property with its own backyard skeet shooting range may be the home for you. (For those not in the know, skeet shooting is when marksmen aim at clay disks automatically flung into the air at high speed from fixed stations.) It doesn't take as much effort to build as a full-fledged rifle range; in fact, "traps" -- the devices that launch the disks -- can be bought as-is (and online!).
Chadwick, Ill.
If archery is more up your alley, then how about this $275,000 home with an indoor archery range? It also comes with $40,000 in retail inventory and displays.

Little Chilli LA-M1 outshines other QRD-based quad-core budget phones, we go hands-on
Spotted outside the auditorium at Qualcomm's China QRD (Qualcomm Reference Design) Summit earlier today were a handful of -- surprise, surprise -- QRD-based smartphones from China, several of which featured the Cortex-A5-based quad-core MSM8x25Q announced back in September. The usual suspects were there in the quad-core lot: Yulong had its Coolpad 5890 (EVDO) and Coolpad 7268 (UMTS), along with Hisense's U958 (UMTS) and Tianyu's K-Touch U86 (UMTS). These all fall within the so-called "¥1,000 ($160) phone" category and yet they are also gifted with a second SIM slot. But what really got our attention was Beidou's Little Chilli LA-M1, which also does dual-SIM (UMTS) but packs an OGS gapless IPS display, while the others came with an LCD panel of obviously lesser quality. Read on to learn more about this mysterious phone, as well as checking out our hands-on photos of the other aforementioned quad-core QRD phones.
Here's a little background: Little Chilli is Beidou's fairly new brand that attempts to follow Xiaomi's online retail model, but without supplying a heavily customized version of Android like MIUI. Most of its earlier models didn't really stand out as they carried almost the same set of components used by other budget phones; but that was until Beidou and ZTE announced their ¥999, Tegra 3-based U950, followed by the Little Chilli Q1 which was officially launched four days ago. The latter went on sale yesterday and the first batch of 20,000 units promptly sold out -- not a surprise since it comes with Tegra 3 and a 4.7-inch 720p IPS display for just ¥999 as well.
Giving the Q1's recent availability, you could say the timing of the LA-M1's announcement today wasn't ideal, which is likely why Beidou has yet to mention the price and availability for its newer phone, but we did hear mentions of a sub-¥1,000 on the show floor. That would be pretty decent for the specs we know so far: 4.5-inch 800 x 480 IPS gapless display, MSM8225Q quad-core chip, dual-SIM support, an eight-megapixel main camera (which produced reasonably good photos, from what we could see), a two-megapixel front-facing camera, and Baidu cloud service integration with 15GB of storage for life, plus another 15GB free for one year. No word on battery size nor battery life yet, but our guess is that neither should disappoint.
While it isn't exactly the most handsome phone on the planet, the M1 that we got to touch actually felt pretty solid, and it ran the native Android 4.1 quite smoothly. So given the choice (and assuming they cost the same), it's either the M1 with its dual-SIM capability but qHD display, or the Q1 with the 720p display but with just one SIM slot. Regardless, Beidou could be well on its way to become the new Xiaomi (sans the software part), though only time can tell whether it has the reliability and after-sale service to prove it. If not, there's still plenty of opportunity for others -- Qualcomm's already completed over 170 QRD-based projects, with about 100 more in the pipeline. Watch out, MediaTek!

Adelie penguins: cool, efficient killing machines
TOKYO (Reuters) - Fish of the Antarctic, be very afraid. There's an unlikely stealth predator on the loose - Adelie penguins.
Forget their ungainly waddling on land or comical bobbing at the ocean's surface. As soon as these penguins dive into the icy Antarctic ocean, they become calculating, efficient killing machines, say Japanese researchers.
"You could say the penguins have an amazing stealth mode," said Yuuki Watanabe, a researcher at Japan's National Institute of Polar Research. "They're great at sneaking up on their prey and taking them unaware."
Watanabe this week released footage recorded in December 2010 showing a bird's eye view of a hunt for fish and small crustaceans called krill, captured using a small video camera strapped to the backs of more than a dozen penguins.
"The krill wiggle their bodies about, they clearly make an attempt to swim off at full speed and escape," Watanabe said of his findings, published in the U.S.-based Proceedings of the National Academy of Sciences this week.
"But that doesn't make the slightest difference to the penguins. They just gobble up the krill that are trying to get away and swallow them whole."
Using the "penguin cams," which were set to automatically switch on when a penguin entered the water and shoot for 90 minutes, Watanabe and his team were able to capture the secrets of penguins on the hunt.
Additional information came from two accelerometers strapped to each bird that measured its head and body movements to calculate how fast it devoured its prey.
"We didn't really know if the penguins caught krill one-by-one. I'd thought that maybe they just got into their stomachs when they were after some other prey," Watanabe said. "But when we saw the footage it turned out the penguins were doing just that, eating these tiny little creatures one after the other."
Not only that, the penguins didn't swim randomly but hung poised on the edge of the ice until a thick swarm neared, then swooped into the water. Footage showed a penguin zooming under the ice and then deeper, its head snapping rapidly up as it fed.
The krill killing-rate was both fast and efficient. The penguins gobbled an average of two krill per second when the krill were clustered in swarms, a much faster rate than under general hunting conditions when the penguins consumed about 244 krill in roughly 90 minutes.
"I was so happy when I got the footage of a penguin going straight into a swarm of krill and gorging itself," Watanabe said.
Penguin research completed, Watanabe now aims to repeat the same exercise with sharks.

"The Dinosaurs in the Details: There were more small meat-eating dinosaurs than first thought"
(Edmonton) University of Alberta researchers used fossilized teeth to identify at least 23 species of small meat-eating dinosaurs that roamed western Canada and the United States, 85 to 65 million years ago.
Until now, only seven species of small two-legged meat-eating dinosaurs from the North American west had been identified.
U of A palaeontologist Philip Currie and student Derek Larson examined a massive dataset of fossil teeth that included samples from members of the families to which Velociraptor and Troodon (possibly the brainiest dinosaur) belong.
"Small meat-eating dinosaur skeletons are exceedingly rare in many parts of the world and, if not for their teeth, would be almost completely unknown," said Larson.
The researchers say the huge increase in the number of small meat-eating species to 23, shows that instead of a few species existing for many millions of years, there were actually many small meat-eating species, each existing for shorter periods of time.
"We can identify what meat-eaters lived in what geographic area or geologic age," explained Currie. "And we can do this by identifying just their teeth, which are far more common than skeletons."
###
The research authored by Currie and Larson (now at the University of Toronto) was published Jan. 23 in the journal PLOS ONE.
