Obama and Castro to meet in rare talks
US President Barack Obama was to hold rare talks with Cuban President Raul Castro yesterday in Havana, setting aside a more than half-century bitter standoff between the US and the communist nation.

The meeting in the Cuban capital’s Palace of the Revolution is only the third formal encounter between Obama and the brother of Fidel Castro, who handed over the presidency in 2008.

At stake is the historic shift to end the Cold War conflict, which has seen Washington try to bring Cuba to its knees through an economic embargo, while Havana, a close Soviet ally, became enemy territory.

Obama, who arrived on Sunday with his family, is the first US president to touch down on the island, barely an hour’s flight from Florida, in 88 years.

As Air Force One landed in Havana, Obama cheerfully began the landmark trip by tweeting in local slang: “Que bola Cuba?” — or “What’s up?”

Later he said that the last US president to visit, Calvin Coolidge in 1928, needed three days to make the trip by train and navy ship.

This is a historic visit,” he remarked to staff at the freshly reopened US embassy in Havana.

The trip has been touted mostly for its huge symbolic value, and comes more than a year after Obama and Castro surprised the world in December 2014 by announcing that their countries would begin normalizing relations.

The presence of a US president on the island for the first time since the 1959 revolution marks a transcendental change in relations between the US and Cuba,” said Michael Shifter, head of the Inter-American Dialogue think tank in Washington.

However, some tough issues are up for discussion.

Although the embargo can only be lifted by the US Congress, where Republicans are far less keen on rapprochement, the Obama administration is chipping away at the edges of the sanctions.

For example, a trickle of US visitors over recent years is soon expected to turn into a flood with the lifting of an onerous requirement that they go to Cuba as part of pre-approved groups.

However, while pushing for an easing of the decades-long sanctions regime, the White House continues to press for greater human rights in a country where the Cuban Communist Party maintains its grip on every key institution and little dissent is tolerated.

Just hours before Obama’s arrival on Sunday, police in Havana arrested dozens of people from a banned group demanding greater human rights. Several had been freed by the end of the day and the rest were expected to be released shortly.

I don’t think Obama’s visit will have an immediate impact on Cuban politics, much less on the near-term decisions of the regime,” Shifter said. “Full normalization will take a lot of time and will be a complex process. To advance, the US Congress needs to go further in lifting the embargo and Cuba needs to speed up its political and economic opening and improve its human rights.”

A heavy police presence was evident when Obama went on his first official event, a visit to the beautifully restored Havana Old Town late on Sunday. Plainclothes agents swarmed through the narrow streets and access to ordinary Cubans was all but impossible, leaving the neighborhood eerily empty.

Maybe they let me come here because they think I’m a tourist with my backpack,” said civil engineer Ariel Hernandez, 42, who was trying to get a glimpse of the president.

Tomorrow, Obama is scheduled to meet with a few human rights activists. He is also to give a speech — the main set piece of his trip — that is to be carried live on Cuban television, an unprecedented concession from the authorities.

He is to round off the trip by attending a baseball game between the Cuban national team and Major League Baseball’s Tampa Bay Rays.

Although meant to be a celebration of shared love for the game, the occasion is also to highlight yet another cause of tension: the talent drain of Cuban stars attracted by the lure of the big-money US circuit.

In another major piece of Latin American business, US Secretary of State John Kerry, who is traveling with Obama, was yesterday due to meet separately with representatives of the Colombian government and the Marxist FARC rebels, according to a Colombian negotiator.

They have been negotiating in Cuba since 2012 to end their more than 50-year war. Both sides have acknowledged that a deadline of tomorrow they had set themselves will pass without the signing of a final accord.

Google’s AlphaGo beats masters at their game again
DeepMind Technologies AlphaGo was the brains behind the go player that won 60 consecutive games in one week in online battles against the worlds top-ranked players, Taiwanese developer Aja Huang (黃士傑) of the Google unit confirmed on Wednesday.

Using the pseudonym Master, AlphaGo played its first online game on Dec. 29 and defeated some of the worlds top players, including Chinas Ke Jie (柯潔) ranked the worlds No. 1 in the Whole History Rating system Nie Weiping (聶衛平) and Chen Yaoye (陳耀燁); Japan’s Yuta Iyama; and South Korea’s Park Junghwan and Cho Hanseung.

Before DeepMind’s revelation, Master’s unconventional strategy, fast reaction and seemingly improbable winning streak had led to speculation that the player was not human.

Yu Bin (俞斌), head coach of Chinas national go team, told Xinhua news agency that no human player could make a move almost every five seconds.

It is highly possible that it is the latest version of an AI [artificial intelligence] player,” he was quoted as saying.

After claiming its 59th win on Wednesday, Master wrote a message on the platform that read: “I am AlphaGo’s Dr Huang.”

We’ve been hard at work improving AlphaGo, and over the past few days we’ve played some unofficial online games at fast time controls with our new prototype version, to check that it’s working as well as we hoped. We thank everyone who played our accounts Magister (P) and Master (P) on the Tygem and FoxGo servers,” DeepMind cofounder and chief executive Demis Hassabis tweeted on Wednesday.

Huang, a professor of computer science at National Taiwan Normal University, was in 2012 employed by the London-based company that was later acquired by Google, and played a key role in AlphaGo’s development team.

According to the Chinese online media outlet The Observer, Master initially registered as a South Korean go player, in an apparent homage to the fact that AlphaGo was certified by the South Korean national go academy as a 9th dan player in January last year after defeating Lee Sedol, a South Korean player with a 9th dan rank, in four games.

Chou Chun-hsun (周俊勳), a professional and the first Taiwanese to play against Master, said he was routed in little more than 40 minutes and had to concede the game.

Master’s strategy defied conventional rules of playing the game, and I knew then that what made those moves was not human. Though the game was a crushing loss, I had a lot of fun losing and I learned some very interesting things from it. I look forward to playing it again,” he added.

Who: AlphaGo
What: It defeated some masters again.

SpaceX launches satellite; Falcon 9 fails sea landing

SpaceX has another launch under its belt, but not another rocket landing.
The leftover first-stage booster hit the floating platform hard on Friday, SpaceX CEO Elon Musk said.
The company never expected to nail this landing because of the faster speed of the booster that was required to deliver the satellite to an extra-high orbit, he said.
SpaceX scored a rocket landing on the ground at Cape Canaveral in December last year, but has yet to nail a trickier barge landing at sea.
However, the good news is that the uncrewed Falcon 9 rocket successfully hoisted a broadcasting satellite for Luxembourg-based company SES.
It was the fifth launch attempt over the past week and a half. An attempt on Sunday last week ended with an engine shutdown a split second before liftoff. Friday’s sunset launch provided a stunning treat along the coast.
As it has tried a handful of times before, SpaceX attempted to land the discarded first-stage booster on a barge, this time 644km off the coast of Cape Canaveral. Right before touchdown, 10 minutes into the flight, the TV camera on the platform cut out, drawing loud groans from the crowd gathered at company headquarters in Hawthorne, California.
“Didn’t expect this one to work (v hot reentry), but next flight has a good chance,” Musk said on Twitter — more than an hour after liftoff.
This mission required that the booster fly much faster than usual and therefore burn up more fuel, leaving less for a precision touchdown.
There were plenty of cheers, nonetheless, as the second-stage successfully lifted the satellite higher and higher, and even more when the satellite separated successfully in full camera view.
Musk said the target altitude of 40,600km was achieved.
“Thanks @SES_Satellites for riding on Falcon 9! Looking forward to future missions,” he said on Twitter.
Musk wants to retrieve and refly boosters to save time and money. Usually, the boosters just fall into the sea.
SES chief technology officer Martin Halliwell last week said that his company would have “no problem” launching a satellite on a recycled SpaceX rocket.
SpaceX is working to recover from a launch accident last summer shortly after liftoff. It hopes to resume space station deliveries for NASA in the next month or so.

Paris climate change deal an actionable plan: Tang Prize laureate

Taipei, April 22 (CNA) Former Norwegian Prime Minister Gro Harlem Brundtland, who was awarded the first Tang Prize in Sustainable Development in 2014, said the Paris Agreement on climate change "provides an actionable global plan for the coming years."

Her remarks came as representatives from more than 160 countries are expected to sign the landmark agreement at United Nations Headquarters in New York later Friday, which is Earth Day.

The pact will be signed by the highest number of governments ever to sign an international agreement, she said, confirming the significance and importance of the agreement, which was reached during the United Nations climate change conference in Paris last December.

"The road to this agreement has been long and uncertain," she said through a statement issued by the Tang Prize Foundation on Friday. "But this year's agreement provides an actionable global plan for the coming years."

On Earth Day, global leaders will gather in New York to sign the agreement, designed to combat climate change and unleash action and investment toward a low carbon, resilient and sustainable future.

The main aim of the agreement is to keep increases in global temperatures this century to well below 2 degrees Celsius and to drive efforts to further limit the temperature increase to 1.5 degrees above pre-industrial levels.

Brundtland, the "godmother of sustainable development," chaired the World Commission on Environment and Development (WCED) from 1984 to 1987. The WCED, also referred to as the Brundtland Commission in recognition of her leadership, coined the term "sustainable development" in a landmark report in 1987 titled "Our Common Future."

The 1987 "Brundtland Report" defined the term "sustainable development" as "development that meets the needs of the present without compromising the ability of future generations to meet their own needs."

The concept supports economic and social development while also highlighting the importance of protecting the environment and natural resources.

Tang Prize Foundation CEO Chern Jenn-chuan (陳振川) visited Paris last year to set up a booth showcasing the foundation's emphasis on sustainable development at an exhibition on the sidelines of the U.N. Climate Change Conference.

The Tang Prize was established in 2012 by Taiwanese entrepreneur Samuel Yin (尹衍樑) to honor leading lights from around the world in four fields: sustainable development, biopharmaceutical science, sinology and rule of law.

The biennial prize takes its name from the Tang Dynasty (618-907 A.D.), a period considered to be the height of classical Chinese civilization, characterized by liberal policies and robust cultural activity.

The Tang Prize will announce its second round of recipients in June.
