Ahead of the Bell: Yahoo to update turnaround bid

SAN FRANCISCO (AP) ? Yahoo's fourth-quarter earnings report will provide an update of new CEO Marissa Mayer's efforts to revive the Internet company's revenue growth.

The results, due out after the stock market closes Monday, cover Mayer's first full quarter as Yahoo's leader. She left Google Inc. to join Yahoo in mid-July, shortly after the third quarter had already begun.

Although Yahoo still hasn't proven it can generate sustained revenue growth for the first time since 2008, investors have already been betting Mayer is on her way to pulling it off.

Yahoo's stock price has been trading above $20 for much of this month, hitting its highest levels since September 2008. The shares closed last week at $20.37. That translates into a gain of about 30 percent since Mayer joined the company.

Much of the confidence in Mayer, 37, may stem from the respect she won while helping to build Google into the Internet's most profitable company during her 13-year tenure there.

Since coming to Yahoo, Mayer has been trying to improve employee morale and intensify the company's focus on mobile and social networking services ? two of technology's hot spots in recent years.

Despite its early enthusiasm for Mayer, Wall Street isn't expecting a lot from Yahoo Inc. Analysts surveyed by FactSet foresee a slight rise in earnings from the previous year, to 27 cents per share, excluding an $83 million charge that Yahoo plans to take to account for the recent closure of its South Korean operations. Investors are likely to pay more attention to Yahoo's revenue, minus ad commissions, which analysts predict will be unchanged from the previous year at $1.21 billion.

The stalled revenue has stemmed from Yahoo's inability to attract more advertising, even though a bigger slice of the marketing budget is being diverted to the Internet. Google's fourth-quarter report released last week showed the Internet search leader's ad revenue, minus commissions, had climbed 17 percent from the previous year.

Federal website hijacked to avenge activist

5 hrs.

WASHINGTON???The hacker-activist group Anonymous says it hijacked the website of the U.S. Sentencing Commission to avenge the death of Aaron Swartz, an Internet activist who committed suicide. The FBI is investigating.

The website of the commission, an independent agency of the judicial branch (http://www.ussc.gov), was taken over early Saturday and replaced with a message warning that when Swartz killed himself two weeks ago "a line was crossed."

The hackers say they've infiltrated several government computer systems and copied secret information that they now threaten to make public.

Family and friends of Swartz, who helped create Reddit and RSS, say he killed himself after he was hounded by federal prosecutors. Officials say he helped post millions of court documents for free online, and that he illegally downloaded millions of academic articles from an online clearinghouse.

The FBI's Richard McFeely, executive assistant director of the agency's?Criminal, Cyber, Response, and Services Branch, said in a statement that "we were aware as soon as it happened and are handling it as a criminal investigation. We are always concerned when someone illegally accesses another person's or government agency's network."

Hours after the hijacking, pages on the USSC.gov website were available only sporadically.

parent - Hacker News


I came to HN because I was interested in how people were using technology to do something interesting for themselves and others. Not math puzzles, or clever programming hacks, or ruminations on various celebrities. This is "making stuff people want"

"Making stuff people want" is a broad mandate. If you can show me new and applicable information about people making money on e-books, I want to see it. If one guy is leveraging Amazon Mechanical Turk to solve CAPCHTAs for gamers, I'm interested. If Chinese firms are selling time levelling up characters for rich westerners, I'd like to know about it.

So as long as HN has articles about people making stuff other people want -- how they decided what to make, how they marketed it, how they worked closely with the target market, and so on -- count me in. I love Erlang Innards as much as the next guy, but after years of reading tons and tons of minutiae around technology, I'd like to see a bit of deeper analysis about how to do something useful with my life, not fluffy nerd candy about whether Haskell is exactly as fast as C or not.

That's my opinion. It's much different than yours, and it's much different than many others, I suspect. This is why we have a voting system, no?

-----


I respectfully disagree with your assertion for the following reasons:

1) While this may be called "hacker" news, there are a great deal of discussions that are about things that hackers are interested in that don't necessarily pertain to hacking.

2) This site is undeniably linked to technological entrepreneurship. eBooks, particularly when they cover something technical, are not only relevant, but the way in which you can make money with them are akin to being able to put together a good website and make money from it.

3) It's not at all uncommon for folks who have worked in the startup business to release or write an eBook. Many things they learn in the process can be applicable to things that are not bookseller related.

In short: this is a site for hackers, not about hacking. There are many other forums out there for such things.

-----


The site is Hacker News - not Programmer News. I understand that there is obviously a strong lean towards programming when thinking of hacking, but hacking can apply to broader topics than just programming. A lot of people are interested in eBooks and marketing and if the post helps you think about those things in a new manner and "hack" the methods of writing, publishing, and marketing your eBook, then I think it's a valid thing to post. If you check out the guidelines for posts on HN, you will see:

"Anything that good hackers would find interesting. That includes more than hacking and startups. If you had to reduce it to a sentence, the answer might be: anything that gratifies one's intellectual curiosity."

I think that a lot of these posts will satisfy a ton of people's intellectual curiosity. If it didn't, why would it make it to the front page in the first place?

Not to mention that if you extrapolate some of the ideas found in these sorts of posts, you could potentially apply them to things like programming and startups. Seems like a beneficial thing to me to have on the site.

I won't go into whether or not some of these posts are that well written or that incisive, but I think a lot of people would agree that they belong here.

-----


I'm not a programmer, though I have some knowledge of programming.

I do think I have a hacker's mindset. That's why I read this site.

When I've posted comments explaining how I created my sidebusiness self publishing books, they've been well received. People here want to know about it.

I make around $1,000 per month in physical and ebook sales. The way I've done it could easily be replicated in a technical field. And from what I've gathered, how to do it is not common knowledge.

So while it's not programming per se, I don't think this site is about programming.

-------------------------------

How I Did It

Since I've alluded to how I've done it, I'll give a top level overview. My book is Hacking The LSAT. Irrelevant to almost everyone here, highly relevant to law school applicants.

http://www.amazon.com/gp/product/0988127903

Createspace allows you to easily publish a physical book on amazon, and keep around 35% of the print price, before discount.

Lightning source lets you sell on other sites such as Barnes and noble, and potentially cause amazon to discount your book.

ELance let me find outsourcers to proofread, format and design my books.

Blogs in your niche are good potential affiliate partners. About 50% of my revenue comes from one affiliate blog.

Relevant forums are a great marketing venue. Hacker News and subreddits may be one of them. Make useful contributions. I created the lsat subreddit, and have an ongoing ask me anything at the other main lsat forum.

While writing, the internet is not your friend. Consider disabling it while writing. I did this for a month by moving to a country without Internet, and my productivity increase 50% (measured in good words written)

Reviews are important on amazon. Give away review copies, and ask people to write honest reviews.

All of this only works if you write a good book. Consider doing it, a good book or e-book can reall set you sort in your niche, even if it's self published.

I haven't gone deep into cross formatting, but calibre is a great conversion program, and liber writer does formatting for kindle. If publishing a kindle book, buy a kindle to test it. Kindle formatting is finicky.

-----


Was it? I didn't mean it that way. The first part or the second part?

I just wanted to show that the community has found such discussions valuable in the past, how it can be done, and what kind of results you can get even from a mid ranked book in a small niche.

-----


No, I didn't. Normally I'm pretty self aware, but we all have our gaping blind spots. No need to be rude.

I can just delete the comment if the whole thing reeks of self promotion.

edit: I typed it out on my phone, which makes it very hard to review the whole thing.

-----


Whether or not an article gets on the front page (or close) depends on whether the herd vote enough for that article, you have a method to determine that, called a vote.

After all, the needs of the many outweigh the needs of the few, or the one.

-----


>>>I'd prefer that spot on the top list to be about programming or something closely related

Now wait a minute. It's people who are putting it up there. Do we have the right to vote or not? And there are lessons in selling eBooks that can be applied to other things too.

-----


Before the internet, before the PC, before even ENIAC, there were writers who made money writing what sold rather than literature. They were considered hacks.

The quintessential person banging away at a keyboard is a writer not a programmer.

-----


hacking: present participle of hack (Verb)
    1. Cut with rough or heavy blows.     2. Ride a horse for pleasure or exercise.

-----


HN has a voting system, so what appears on the front page are articles HN readers want or find interesting.

If you have a problem with a front page article, you should know that some people found it interesting and that after all, you can't agree with everybody on HN.

What you are suggesting is a matt2000'ing of HN. (matt2000 being your username.)

Canada's Dextre robot refuels faux satellite from the ISS in first-of-a-kind test

Canada's Dextre robot refuels faux satellite from the ISS in first-of-a-kind test

Move over, Canadarm. You may have helped the space shuttle fleet repair the Hubble Telescope and build the International Space Station, but there's another robotic tool that's the apple of the Great White North's eye. Dextre, the Canadian Space Agency's dual-armed mechanical "handyman," has successfully refueled a faux satellite from the ISS as part of NASA's and the CSA's joint Robotic Refueling Mission. Not only did the exercise demonstrate how satellites could be juiced up in space and have their lives extended, but the CSA says it's a first for the history books, to boot. Since 2011, Dextre completed a trio of tests to show how it could service satellites that weren't built for being pried opened in space. Late this week, NASA and CSA robotics controllers removed two safety caps from a washing machine-sized mock satellite, snipped two sets of retaining wires and pumped in a bit of ethanol. Sure, you could take a Frankenstein-like approach and cobble together new satellites from old ones, but Dextre's trials indicate there's promise for a proactive tactic that would keep existing hardware humming.

Dextre Successfully Refuels Mock Satellite and Aces a Major Test for Space Robotics

Longueuil, Quebec, January 25, 2013 - Dextre, the Canadian Space Agency's robotic "handyman" on board the International Space Station (ISS), made space history last night by successfully refueling a mock satellite on the exterior of the station. Topping off the satellite's fuel tank was the pivotal task in the experimental Robotic Refueling Mission (RRM), a collaboration between the National Aeronautics and Space Administration (NASA) and the Canadian Space Agency (CSA) to demonstrate how robots could service and refuel satellites on location in space to extend their useful lifetime.

For RRM, NASA's Goddard Space Flight Center designed a module simulating a satellite, as well as custom power tools for Dextre. Since RRM operations began in 2011, Dextre has performed three series of tests to show how a robot could service satellites, which were designed never to be opened in space. In this latest set of operations, Dextre removed two safety caps, cut through two sets of thin retaining wires, and finally transferred a small quantity of liquid ethanol into the washing machine-sized module. The latter maneuver was particularly tricky, since handling liquids in space required perfect precision to prevent dangerous leaks. The specialized tools built for the job allowed Dextre to seal the connections between the tool and the fuel valve to eliminate the possibility of leaks. Adding to the level of difficulty was the fuel hose itself, which adds additional forces that tend to pull Dextre's hands. It took the combined skills of the experienced NASA and CSA robotics controllers to pull off this first-of-a-kind space refueling demonstration successfully and without any mishap.

RRM is a significant step in pioneering robotic technologies and techniques in the field of satellite servicing-saving ailing space hardware by refueling or refurbishing them before they become space debris. The ability to refuel satellites in space could one day save satellite operators from the significant costs of building and launching new replacement satellites. With over 1100 active satellites currently operating in the near-Earth environment (many of them worth hundreds of millions of dollars), and an additional 2500 inactive satellites still orbiting around our planet, the savings could be substantial.

Struggling dolphin dies in polluted New York City canal

NEW YORK (Reuters) - A distressed dolphin died on Friday after wandering into a notoriously polluted New York City canal, according to a marine research group that was monitoring the animal.

The animal, a common dolphin, died in the shallow waters of Brooklyn's Gowanus Canal, said Valentina Sherlock, an employee at The Riverhead Foundation for Marine Research and Preservation, whose biologists were keeping watch over the dolphin on behalf of police and the National Oceanic and Atmospheric Administration (NOAA).

A decision on what to do with the carcass would likely be made on Saturday, Sherlock said.

Earlier in the day, the animal appeared to be disoriented and seemed to be struggling to avoid getting stuck in the muddy floor of the shallow canal, said Mendy Garron, a marine mammals response coordinator from NOAA.

"When we see animals that come in, especially this far, and get into these situations they are typically very disoriented, and it's an indicator that they're either sick or injured," Garron said, adding that healthy common dolphins are rarely seen separated from their pod.

"They usually don't survive these types of stranding events," she said.

The dolphin's sex and age were unknown.

Some New Yorkers who visited the dolphin on Friday took to the Internet to describe its plight.

"This is stupid and I'm sorry, but it does seem like dolphin is looking up at humans for help," Dave Bry, a writer who lives in New York, wrote on Twitter as he watched the scene from a bridge over the canal. "Jeez. Could that be?"

The Environmental Protection Agency declared the Gowanus Canal a Superfund site in 2010, calling it one of the country's "most extensively contaminated water bodies," laced with heavy metals, coal tar wastes and other pollutants from the factories and tanneries that have lined its banks.

The EPA is still working on its plan to spend hundreds of millions of dollars of federal money to clean up the canal.

In late December, a finback whale died after beaching in the New York City borough of Queens.

Egypt anything but peaceful on anniversary of uprising

CAIRO/ISMAILIA, Egypt (Reuters) - Egypt's armed forces deployed troops in the city of Suez early on Saturday after nine people were shot dead during nationwide protests against President Mohamed Mursi, underlining the country's deep divisions as it marked the second anniversary of the uprising that toppled Hosni Mubarak.

Eight of the dead, including a policeman, were shot dead in Suez, and another was shot and killed in the city of Ismailia, medics said. Another 456 people were injured across Egypt, officials said, in unrest on Friday fuelled by anger at Mursi and his Islamist allies over what the protesters see as their betrayal of the revolution.

Mursi said the state would not hesitate in "pursuing the criminals and delivering them to justice". In a statement, he also called on Egyptians to respect the principles of the revolution by expressing their views peacefully.

The troops were deployed in Suez after the head of the state security police in the city asked for reinforcements. The army distributed pamphlets to residents assuring them the deployment was temporary and meant to secure the city.

"We have asked the armed forces to send reinforcements on the ground until we pass this difficult period," Adel Refaat, head of state security in Suez, told state television.

Friday's anniversary laid bare the divide between the Islamists and their secular rivals.

The schism is hindering the efforts of Mursi, elected in June, to revive an economy in crisis and reverse a plunge in Egypt's currency by enticing back investors and tourists.

Inspired by the popular uprising in Tunisia, Egypt's revolution spurred further revolts across the Arab world. But the sense of common purpose that united Egyptians two years ago has given way to internal strife that already triggered bloody street battles last month.

Thousands of opponents of Mursi massed on Friday in Cairo's Tahrir Square - the cradle of the revolt against Mubarak - to rekindle the demands of a revolution they say has been hijacked by the Muslim Brotherhood, the group from which Mursi emerged.

In Suez, the military deployed armored vehicles to guard state buildings, witnesses and security sources said, as symbols of government were targeted across the country.

Street battles erupted in cities including Cairo, Alexandria, Suez and Port Said. Arsonists attacked at least two state-owned buildings. An office used by the Muslim Brotherhood's political party was also torched.

"Our revolution is continuing. We reject the domination of any party over this state. We say no to the Brotherhood state," Hamdeen Sabahy, a popular leftist leader, told Reuters.

The Brotherhood decided against mobilizing for the anniversary, wary of the scope for more conflict after December's violence, stoked by Mursi's decision to fast-track an Islamist-tinged constitution rejected by his opponents.

The Brotherhood denies accusations that it is seeking to dominate Egypt, labeling them a smear campaign by its rivals.

'LEAVE! LEAVE! LEAVE!'

There were conflicting accounts of the lethal shooting in Suez. Some witnesses said security forces had opened fire in response to gunfire from masked men.

News of the deaths capped a day of violence that started in the early hours of Friday. Before dawn in Cairo, police battled protesters who threw petrol bombs and firecrackers as they approached a wall blocking access to government buildings near Tahrir Square.

Clouds of teargas filled the air. At one point, riot police used one of the incendiaries thrown at them to set ablaze at least two tents erected by youths, a Reuters witness said.

Skirmishes between stone-throwing youths and the police continued in streets around the square into the day. Ambulances ferried away a steady stream of casualties.

Protesters echoed the chants of 2011's historic 18-day uprising. "The people want to bring down the regime," they chanted. "Leave! Leave! Leave!" chanted others as they marched towards the square.

"We are not here to celebrate but to force those in power to submit to the will of the people. Egypt now must never be like Egypt during Mubarak's rule," said Mohamed Fahmy, an activist.

There were similar scenes in Suez and Alexandria, where protesters and riot police clashed near local government offices. Black smoke billowed from tires set ablaze by youths.

In Cairo, police fired teargas to disperse a few dozen protesters trying to remove barbed-wire barriers protecting the presidential palace, witnesses said. A few masked men got as far as the gates before they were beaten back.

Teargas was also fired at protesters who tried to remove metal barriers outside the state television building.

Outside Cairo, protesters broke into the offices of provincial governors in Ismailia and Kafr el-Sheikh in the Nile Delta. A local government building was torched in the Nile Delta city of al-Mahalla al-Kubra.

With an eye on parliamentary elections likely to begin in April, the Brotherhood marked the anniversary with a charity drive across the nation. It plans to deliver medical aid to one million people and distribute affordable basic foodstuffs.

Writing in Al-Ahram, Egypt's flagship state-run daily, Brotherhood leader Mohamed Badie said the country was in need of "practical, serious competition" to reform the corrupt state left by the Mubarak era.

"The differences of opinion and vision that Egypt is passing through is a characteristic at the core of transitions from dictatorship to democracy, and clearly expresses the variety of Egyptian culture," he wrote.

Mursi's opponents say he and his group are seeking to dominate the post-Mubarak order. They accuse him of showing some of the autocratic impulses of the deposed leader by, for example, driving through the new constitution last month.

"I am taking part in today's marches to reject the warped constitution, the 'Brotherhoodisation' of the state, the attack on the rule of law, and the disregard of the president and his government for the demands for social justice," Amr Hamzawy, a prominent liberal politician, wrote on his Twitter feed.

The Brotherhood says its rivals are failing to respect the rules of the new democracy that put the Islamists in the driving seat via free elections.
