China successfully launches two more Beidou navigation satellites

China has moved a step closer to completing its own navigation and positioning satellite network with the launch of two more navigation satellites.

China plans to launch 35 navigation satellites

It brings the Beidou system, which became operational with coverage of China last December, to 13 satellites.

To have global coverage, the country eventually aims to have 35 satellites in orbit by 2020.

China hopes that Beidou will wean it off the US Global Positioning System.

Just like GPS, the Chinese system is designed to let users determine their positions to within a few meters.

Beidou, also known as Compass, has been developed for both military and civilian uses.

The two satellites went up on Monday morning from the Xichang Satellite Launch Centre in southwest Sichuan province.

They were carried on a Long March-3B rocket, according to the state-run Xinhua news agency.

"The two satellites will help improve the accuracy of the Beidou, or Compass system," Xichang Satellite Launch Centre said in a statement carried by the agency.

• Sat-nav systems determine a position by measuring the distances to a number of known locations - the spacecraft constellation in orbit
• In practice, a sat-nav receiver will capture atomic-clock time signals sent from the satellites and convert them into the respective distances
• A sat-nav device will use the data sent from at least four satellites to get the very best estimate of its position - whether on the ground or in the sky
• The whole system is monitored from the ground to ensure satellite clocks do not drift and give out timings that might mislead the user

Now partially operational, Beidou makes China only the third country in the world, after the US and Russia, to have its own navigation system.

Russia's Glonass satellite network has 31 satellites in orbit, but only 24 of them are operational. Four more are in reserve, one undergoing trials, and two under maintenance.

According to the Russian Space Agency, Roscosmos, Russia plans to spend $694m (£427m) on its Glonass system this year.

At a recent annual Satellite Navigation Forum in Moscow, Russia's deputy prime minister Vladislav Surkov said that more than 300 billion roubles (£6bn, $10.2bn) have been budgeted to further develop Glonass and bring 30 satellites into operation by 2020.

Europe has also been building a navigation system, called Galileo, which has two satellites in orbit, launched in October last year. The next two are scheduled to follow later this year.

The space project of the European Commission, the EU's executive arm, plans to have all 26 Galileo satellites in orbit by the end of 2015. - BBC Newscribe : get free news in real time

China has successfully launched a pair of navigation satellites. The launch took place on Sunday Morning from Xichang Satellite Launch Center and marks the first time the Long March 3B launch vehicle has been used for this kind of mission.

The Compass Navigation Satellite System is China’s second-generation satellite navigation system, capable of providing continuous, real-time passive 3D geo-spatial positioning and speed measurement.

Bersih 3.0: the good, bad and ugly Malaysians

When people who want change take to the streets, some stick to the perimeters of the law while others, with ulterior motives, break barriers and turn things unruly. 

BERSIH 3.0 co-chairman Datuk Ambiga Sreenevasan's call for people to show their displeasure and demand for electoral reforms on Saturday brought out thousands of Malaysians from all races and walks of life in a colourful expression of free will.

But Ambiga's calls also brought out the professionals the hardcore saboteurs who dreamt of regime change and the provocateurs who simply wanted chaos and trigger a mass protest that could eventually lead to the toppling of a democratically-elected government.

These people dream of sustained protests on the streets that eventually drive away tourists and worry investors.

Taking law into their own hands: Rioters using sticks and helmets to smash a car carrying the TV3 news crew as it was leaving Jalan Tun Perak, Kuala Lumpur, in 1999, soon after the verdict on Anwar was delivered.

 

Such sustained protests were last seen during the reformasi years in the 1990s with the arrest and jailing of the then Deputy Prime Minister Datuk Seri Anwar Ibrahim.

The same man was present on Saturday, after warning months earlier that Middle East-style protests could hit South-East Asian countries if the reforms were delayed.



If Ambiga thought she could keep everyone within limits, then she was sadly mistaken.

Different people read differently into a mass protest and the hardcore politicians in the crowd have other ideas too.

Reportedly, PKR deputy president Azmin Ali had egged on the crowd to break down the police barriers at Dataran Merdeka that were put up due to a court order declaring the place “out of bounds”.

Ambiga had given the order to disperse at about 3pm, but some marched forward and broke thorough the barriers.

They pelted a police car with bottles and stones, jumped on it and smashed the windscreen and later overturned it. They then attacked a police motorcycle and tried to grab a policeman's gun.

The attack on the police car was reminiscent of an incident in 1999 when a TV3 car was set upon during the reformasi protest.

At a press conference later, Ambiga expressed shock over the turn of events.

The initial carnival mood where people were giving flowers to FRU personnel, who reciprocated by wearing them, was hijacked by a section of the crowd.

Ambiga described the violence as “highly unusual” and suspected that it could have been instigated by agent provocateurs.

The problem is that while Ambiga heads a civil rights movement which is winning support by the day from young people, who incidentally make up the bulk of new voters, she has chosen to tie that movement with Opposition politics.

She has given Opposition leaders an opportunity to ride on the Bersih movement.

Ostensibly, independent non-politicians fill the Bersih steering committee but they are also enthusiastic Pakatan Rakyat supporters.

The Opposition leaders are hardened politicians who have served time in jail, have courted arrest many times and are willing to take greater risk to trigger mass action.

During the two previous Bersih rallies in November 2007 and July 9 last year, a similar scene took place; a section of the crowd taking over the protest and turning it violent.

The same police force, which was peaceful in the morning, was forced to fire tear gas and arrest protesters in the afternoon.

It brings to mind DAP vice-chairman Senator Tunku Abdul Aziz Tunku Ibrahim's warning that by not using the stadiums offered, Bersih 3.0 “encourages Malaysians to break the law”.

He had said he supported an individual's constitutional right to assembly but felt that it must be exercised within the provisions of the law. “As a lawmaker I am not willing to break the law.”

That same advice could also apply to Ambiga, a lawyer, but for politicians who desire regime change it is another matter.

The clock has been turned back on a burgeoning civil rights movement, and what could have been a shining example of peaceful protest, turned into a violent demonstration.

There were no warnings of reprisals in the days leading to Bersih 3.0, no roadblocks set around the city and no arrest of people streaming in for the protest.

But all that was blown away after some protesters breached the police barriers.

Many of the protesters who turned up on Saturday were those who genuinely wanted to bring about positive change. They had meant well and they represented middle Malaysia.

And, for the thousands of young Malaysians who braved Ambiga's call for a sit-in protest over the slow pace of electoral reforms, it was their first baptism of fire and one that they can wear as a badge of honour.

A father's lament: The real world is not a game!

Learning should be fun, but that doesn't mean we should be trying to hook kids into playing computer games that just happen to teach. 

There was something about the Mama Bear family tech conference a week ago that creeped me out. I am the father of a 5-year-old boy, and perhaps a third of the people at this conference were trying to build apps for him. All the apps were well-intentioned. All were, at some level, educational.

Still, all the apps felt wrong to me. I wanted my son to have nothing to do with any of them.

I've been trying to understand why these educational apps were getting under my skin to this extent. It's not like I'm anti-technology when it comes to my child. He plays Angry Birds. We watch TV (together). He's a child of technology; how could he live in my house and not be?

A psychiatrist friend, listening to me rant about how these apps are trying to wilt my son's brain, sympathized, but not completely. Yes, he said, computer games can be addictive. In fact, in his opinion, teaching kids to expect the world to work like a computer game deprives them of learning real-world life skills.

But, he said, a truly good educational app can be effective like a book, or a teacher. You can't stick everything that pops up on a kid's iPad into the "evil" category.

So where are the really good apps?

A few days ago, I handed my son a Vinci tablet to try out. This is another well-intentioned product for young children. It comes with pre-installed educational games carefully geared to kids up to about my son's age (actually he's a little old for it, but I occasionally make him earn his keep as a product reviewer).

I had the same feeling of foreboding about this product as I did about many children's apps I see. The Vinci reinforced this, unfortunately. While the game did in fact have educational payloads, the mechanics were, for the most part, dumb. How does pressing a button at exactly the right time to jump over a beach ball on-screen teach anything but how to operate a game, no matter what the game says it's supposed to be about?

The boy liked the tablet and its apps. But it's how he liked them that bothered me. The software sucked him in, and whatever lessons it tried to teach him were obstacles that seemed about as interesting as the flatly drawn beach balls. The real red flag came when I told my boy it was time to put the tablet down. He was so dialed in to the game mechanics that he panicked. He wasn't in learning mode, he was in addiction mode.

Did he retain the factoids and basic math and spelling skills he learned while playing? I think so. But I don't want him learning this way.

There is hope, though.

On the DIY app, kids snap pictures of their projects. On the Web site, shown, family and friends can award badges.

Yesterday, I read about the launch of DIY, a site and app for kids that's supposed to be a social destination for them to share their creative projects. They upload photos of stuff they've designed, built, written, or drawn, and then their friends and family members can award them badges.

Something about this site appealed to me as a father. Why was it better than all the learning games, with their impressive educational pedigrees? I couldn't put my finger on it. So I called up DIY's CEO, Zach Klein (formerly of Vimeo). Klein isn't a father himself, but he understands the child's mind. In a few words he crystalized for me what I find distasteful about most kids' programming.

"They are gravity-fed," he says. "There's a path of least resistance to get to the next screen." The player's job is to find that path, he says. Games like this "infantilize children."

The real world doesn't work like this. There are no shortcuts in life. You don't get a big reward for each tiny action. Real rewards take real work.

DIY, he says, "gives children more responsibility than they are used to, not less." And the rewards aren't programmed. They come from peers and family. "We want kids to feel satisfaction, but we're suggesting it will take time and craft and love to earn it."

DIY is in a very early stage, and is too basic at the moment. In the interest of protecting kids, there's no personal information anywhere on the system; kids' identities are masked behind handles, and if a family member awards a kid a sticker, the kid can't see who it came from. But the thinking of DIY is right, at least to me: Encourage kids to engage with the real world. Use social-networking mechanics to reinforce it.

I loaded the DIY app on to my old iPhone 3G. I plan to let my boy use the app on this device without supervision. It's the first app I've seen that passes that test for me. I'm not sure he'll use it, but I bet he will. And I like it, because it's an accessory to his physical world, not a replacement for it.
