EARLY CHRISTIANS like the apostle Paul are said to have rejected the “vengeful” God of the Old Testament. In his place, the church fathers gave us the man Jesus, who they said was synonymous with love. Hate no longer had any place, including the hatred of evil. So whereas the God of Israel says explicitly in Malachi: “I love Jacob but I hate Esau” – presumably because the former represents those who struggle for peace, while the latter has become a symbol for those who “live by the sword.”
In the 20th century genocide was commonplace. A few of the better-known examples include the Turks slaughter of the Armenians during World War I, the Germans attempted extermination of the Jews, the Khmer Rouge and its killing fields in Cambodia in 1975-78, the Hutus hacking to death of the Tutsis in Rwanda in 1994, the ethnic cleansings of Croats by Bosnian Serbs and the wholesale slaughter of black Christians in the Sudan by militias.

Doctors issue warning on Facebook use, which they say can lead to teenage depression | The Australian
Researchers disagree on whether it's simply an extension of depression some kids feel in other circumstances, or a distinct condition linked with using the online site.
But there are unique aspects of Facebook that can make it a particularly tough social landscape to navigate for kids already dealing with poor self-esteem, said Dr Gwenn O'Keeffe, the lead author of new American Academy of Pediatrics social media guidelines, published today.
With in-your-face friends' tallies, status updates and photos of happy-looking people having great times, Facebook pages can make some teenagers feel even worse if they think they don't measure up.
It can be more painful than sitting alone in a crowded school cafeteria or other real-life encounters that can make kids feel down, Dr O'Keeffe said, because Facebook provides a skewed view of what's really going on.

Another is referred to as a "raghead."
When a local man is shown running away from an explosion, a soldier is heard to say that the blast "scared the f... out of that mufti."
A number of soldiers list their employer as a "f...ing ranga", some under their listing for Australian Defence Force.
Acting Chief of Army Paul Symon said the behaviour undermines everything Australia is trying to achieve in Afghanistan.
"There will be thousands of soldiers disgusted at what we're looking at," Major-General Symon told the Seven network.

Around 300 campers, including two school groups of 60 students, had to be evacuated to higher ground when their camp sites were flooded at Wilsons Promontory.
The State Emergency Service (SES) received around 110 calls for help from residents in East Gippsland including 100 from Moe and Foster where homes were inundated and roads cut by water.
Mallacoota, in the far eastern corner of the state, received 123mm of rainfall and the only road into town, Mallacoota Road, was closed off last night, turning the town into an island.
An SES spokeswoman said emergency workers had to rescue ten people whose cars stalled after they attempted to drive through flood water.
At Fish Creek, residents of five homes were evacuated and taken to a relief centre at the local town hall.
It was April 27, 1986, when radiation alarms sounded at Sweden's Forsmark nuclear power plant, radiation 14 times normal the cause, though the radiation did not originate at Forsmark. Soon after, the then-Soviet Union revealed Chernobyl's nuclear accident, an accident across the Baltic Sea and many hundreds of
kilometers southeast of Sweden. Meanwhile, not far up Sweden's Baltic Coast from Forsmark sat the city of Gavle, almost 1,600 kilometers from Chernobyl, but soon to be lastingly impacted by it.
It was 21 years after the Chernobyl fire, May 2007, when one Swedish paper headlined "Swedes still dying from Chernobyl radiation", Gavle and what is occurring there figuring prominently in the English-language article. A heavy rainstorm had struck Gavle in 1986, doing so as a cloud of Chernobyl's fallout was overhead.
Prevailing winds at that time had driven radioactive clouds from Chernobyl over parts of Scandinavia, the International Atomic Energy Agency (IAEA) providing a report on the early amounts of radiation registered in Chernobyl's aftermath, a report where Gavle is again significantly featured. A recent article on Time.com, “Fukushima: Chernobyl Redux?”, describes the immediate effect Chernobyl had on Gavle in fairly plain terms. Quoting from Time:
I remember that after Chernobyl there was a town in Northern Sweden called Gavle. The radioactive cloud went over the town and it started raining heavily and there was a lot of deposition of radioactive particulate material that was caught into surfaces of roads and buildings. There was a high level of cesium-137. When we went there and waved our Geiger counters about the counters maxed out - it was that bad.According to a 2006 Swedish study published in the American Journal of Industrial Medicine, it appears Sweden experienced approximately a thousand excess fatalities because of Chernobyl, the number expected to increase, the cases concentrated proportional to the levels of radioactive exposure. As might be imagined, there were other effects as well, such as effects with an impact on unborn children.

RSA is a subsidiary of data storage giant EMC. The tokens are small devices which generate a digital security code that changes every 60 seconds. It is usually used together with a static PIN or password to access a computer system.
Other Australian customers include Telstra and Virgin Blue, the federal departments of Defence, Treasury, Prime Minister and Cabinet, Veterans Affairs and Parliamentary Services, along with the Australian Electoral Commission, Family Court, Geoscience Australia, AusAid and Crimtrac.
RSA has refused to say how its system was compromised and what specific kinds of threats its customers are facing. Its Web site continues to claim the SecurID system has never been breached in 15 years.
In an open letter to customers, RSA's North American HQ said an investigation into the attack revealed that it had "resulted in certain information being extracted from RSA's systems". The stolen data was "specifically related to RSA's SecurID two-factor authentication products" and the attack "could potentially be used to reduce the effectiveness of a current two-factor authentication implementation as part of a broader attack," the security firm said.
Observers say one potential weakness that could be exploited involves a factory-installed key called a seed. Typically 16 characters long, it is different for each token and is stored on a corresponding server program, which authenticates the session each time a user connects to a secure network.
If the database containing customers' seeds was cracked, the intruder might still not know which user had which seed, but cryptographers said it would be possible to use a reverse-engineered version of the RSA algorithm to determine that information by simply capturing a single log-in session.

The quad-SSD on the VAIO-Z allows you to use them in a single RAID stripe, which boosts the drive data load at up to 6.2 times faster than a regular 5,400rpm notebook HDD. Another interesting feature is the switchable graphics, which allows you to have options to choose from the powerful NVIDIA GeForce GT 330M graphics or the energy-efficient integrated to save battery.
So, when you’re into gaming or watching HD videos, you’ll need to choose the NVIDIA, and when you’re down to doing simple tasks such as word processing, you can toggle to the integrated graphics to preserve the battery.
One of these upgraded Sony VAIO-Z laptops will run you about $1,900, will be available in the US in April and Europe will get it earlier by end of March.

Ten pilots were fired after they failed tests, including one who was found over the limit on two occasions, according to the list released by Aviation Minister Vayalar Ravi in parliament on Thursday.
The fifty-six pilots worked for the state-owned national carrier Air India, as well as private airlines Jet Airways, Indigo, SpiceJet, GoAir, and Kingfisher.
Twenty-three pilots from India's top airline company Jet Airways failed their tests, but the airline did not sack any of them, putting them on suspension and subjecting them to a pay cut instead.
The list of pilots was issued a day after two pilots were found flying passenger planes with forged qualifications, deepening concerns about safety on India's booming airlines.
India's Directorate General of Civil Aviation (DGCA) drafted regulations recently, stipulating that pilots arriving to work drunk would be grounded for three months for a first offence and lose their flying licence after a second.
No more such cases have emerged since the DGCA's regulations came into effect in December 2010.
Rising incomes and the liberalisation of the airline market in the 1990s has led to an explosion in air travel in India, with passenger numbers up 25 per cent over the last 12 months.
With new routes and new aircraft being regularly inducted, the half-dozen low-cost Indian airlines are competing fiercely for locally trained pilots. Many employ foreign pilots, often from eastern Europe.
Footy season started properly at the weekend and the change is more pronounced than the turning of the seasons. This year the underbelly of professional high-collision sport is under scrutiny on a level of forensic detail never seen before.
On Friday the players in America's National Football League went on strike, not just over how to divide the spoils of the NFL's multibillion-dollar entertainment cartel, but over player safety. The players are refusing to expand the regular season from 16 games to 18 because the injury and attrition rate is so horrific (the average pro career is four years).

The NFL Players Association wants a reduction in the number of full contact drills at training, and a reduction in the length of pre-season training. The 2011 NFL season may be curtailed or even suspended as the two sides grind away in the courts.
The shadow hanging over these negotiations can be summed up in three letters, CTE, a shadow which also hangs over Australian football, particularly rugby league, but also rugby union and Australian rules football. CTE stands for chronic traumatic encephalopathy. It is caused by repetitive brain trauma: multiple concussions and sub-concussions.
The first case of CTE was not diagnosed until 2002, when doctors examined the brain of a former player for the Pittsburgh Steelers, Mike Webster, who anchored the Steelers to four Super Bowl championships and was elected to the game's Hall of Fame.
Fame and glory did not follow Webster after football. He died at 50, after a decade of acute pain from football injuries, plus depression, amnesia and early-onset dementia. He spent his last years living in his pick-up truck and sleeping on railway stations.
Since this belated discovery of a measurable link between CTE and professional contact sport, CTE has been found in the brains of a number of former athletes who died young, some by suicide, most notably the pro wrestler Chris Benoit, who murdered his wife and son before committing suicide in 2007.
CTE is also casting a long shadow over the cynicism of the National Hockey League, which has always tolerated on-ice fighting as part of its culture. Last week, Air Canada threatened to withdraw its sponsorship if legal action was not taken against a player who rammed another player into a wall, causing serious injury. Ice hockey also has the legacy of Bob Probert, who died last year aged 45. Probert was a goon, a designated enforcer, who ranks fifth all-time in the hockey league's list of most penalised players.
Probert's family donated his brain to science. Last month, researchers announced the autopsy had revealed evidence of CTE. No surprise. CTE is now part of society's growing awareness of the real costs of pro contact sport. Which brings me home, to the opening game of the 2011 rugby league season, which I attended, between the Sydney Roosters and the South Sydney Rabbitohs. Here was a game featuring a young player who is not waiting to be brain-dead by 60. The catalyst for the Roosters giving away a commanding lead was the penalty-conceding antics of forward Jared Waerea-Hargreaves, who is so intent on making a reputation as a hard man that he managed to fire up the Souths team.
Even Rugby League's latest pin-up boy, the Wests Tigers captain and brilliant playmaker, Benji Marshall, is embroiled in a violence-related incident that is now before the courts. His predecessor as the face of the game, Manly's Brett Stewart, was dropped from pin-up status after allegations of excessive drinking at a season-launching social event. A year later, the fall-out from this event continues to be contested.
This is business as usual for Rugby League, even as the game continues to evolve as a brilliant spectacle that is perfect for TV. The only thing that stands between league and a billion-dollar TV pay-off when its broadcast rights are negotiated this year is the game's underbelly: brilliant game, brainless sub-culture. For years, the number of scandals involving Rugby League players has been a conveyor belt of incidents involving drinking, gambling, drug-taking, sexual assault, and public defecating, urinating and brawling. The number of incidents has been beyond all statistical probability.
But the amount of brainless behaviour does make sense when placed within the context of league's pervasive culture of illegal conduct, in plain sight. Take the play-the-ball. It is the engine-room of the game, and it is a joke.
Players have enough time to make a cup of coffee and call their girlfriends as they lie on the tackled player until their mates get back into the defensive line, while the referees pretend it's not happening. When you are trained to get away with things on the field, it must spill over into conduct off the field.
Let us not forget Aussie rules, where the cheap shot is enshrined in the culture of the game. So much of the action in the AFL takes place off the ball as players constantly niggle, elbow, thump and verbal each other. Many AFL stars have been bullies first and athletes second.
Every parent should drill this fact into their kids: beauty and bravery on the sporting field does not translate to beauty and bravery off the field. To survive in professional contact sport you need a streak of mongrel and with some players mongrel is all there is

Professor Andrew Dempster, from the School of Surveying and Spatial Information Systems at the University of New South Wales, says the GPS has become an integral part of our lives.
"Most people wouldn't be aware of how many of their daily systems require GPS to work," he said.
"It is not just a system to provide you with position in fact each GPS satellite is an atomic clock.
"Those clocks are used to synchronise a whole range of things, from radar for air traffic control... to the official time for Australia."
Professor Dempster spoke this week at a workshop in Canberra on GPS vulnerability organised by UNSW's Australian Centre for Space Engineering Research.
The workshop discussed threats to GPS including jamming and "spoofing" devices.
He says the weak radio signals used by GPS receivers makes them vulnerable to interference and attack.
"The satellites are 20,000 to 26,000 kilometres away and the power that they're transmitting is not much more than a light bulb," he said.
"By the time they get to the surface of the Earth they are very weak."
A recent survey by UNSW researchers found radio signals from a television transmission tower in the northern suburbs of Sydney disrupted GPS receivers, despite it using a different frequency.
"The SBS transmission tower in Artarmon has a transmission frequency about one third of the GPS central frequency," Professor Dempster said.
"The third harmonic falls in or near the GPS band and we have observed that there is interference to GPS."
Professor Dempster says electronic devices such as computer and portable music players can also interfere with GPS receivers.
GPS under threat
Recently, there have been claims radio waves coming from 4G transmission towers - the next phase of mobile telephone and internet services - are interfering with GPS signals.
"In 2010, the [Federal Communications Commission] in the US approved a company called Light Squared to use LTE equipment - the next generation of mobile phone technologies," Professor Dempster said.
"It will be operating in a band right next to GPS and those transmissions will be relatively strong.
"The lesson we need to learn from the US experience is not to use spectrum right next to satellite navigation."
But Professor Dempster says the biggest threat to GPS could come from criminal or terrorist activities.
His says UNSW is working with the University of Adelaide and GPSat Systems to develop jammer-detection technology that should reduce the threat.
"We are looking at setting up a system where we [can] identify the location of a jammer," he said.
"By using various techniques we are hoping that we'll be able to say 'OK, that jammer is at point X, Y, Z."å

CardioArm can assist surgeon’s procedures, slithering into places in the body too tight or dangerous for ordinary medical tools to enter. Though it’s hardly comfortable, Snakebot is revolutionising the way heart surgery is performed, mitigating the need for open heart surgery.
Rather than having to crack open patients’ ribcage during heart surgery, this slippery little sucker buries itself deep inside your chest via a 2cm hole in your solar plexus and slithers around your organs.
The inventors of CardioArm say this technology has the potential to minimise the time it takes for patients to recover from heart surgery. Dr Howie Chosets from the University of Cargenie Mellon in Pennsylvania told Discover magazine: “Instead of cracking open a person’s chest we can do a surgery and send patients home the next day.”
The roboticist plans to test the device in other surgeries such as ablation, which involves using lasers to burn away small amounts of heart tissue to correct an abnormal beat. Surgery isn’t the only thing on Dr Chosets' agenda however, the robotics believes Snakebot could assist in archaeology fields as well.
Dr Chosets told IEEE's Spectrum:“We’re hoping to use a remote-controlled robot to go through small caves in Egypt and find remains of ancient Egyptian tombs.”

For decades, the primary method of storing data on a computer has been on a magnetic disc. Even after the disc has been formatted and data removed, most of the information can still be recovered by skilled forensics specialists. But increasingly, computer makers are moving to a new technology called solid-state drives (SSDs), which are faster, quieter and less susceptible to physical shocks as they store data on memory chips instead of spinning magnetic discs. Graeme Bell and Richard Boddington of Perth's Murdoch University, in a paper published in the Journal of Digital Forensics, ran tests which discovered that with SSDs, once the user erases their hard drive, the data is gone forever in minutes and cannot be recovered.
The pair said the results were "remarkable" and revealed that SSDs are "quite capable of essentially near-complete corrosion of evidence entirely under their own volition". In their experiments, with a traditional hard drive almost all files were preserved after the user runs a quick format, and those files could later be recovered perfectly. "In contrast, with SSD we saw that shortly after reboot the entirety of the files were damaged and almost all were purged completely, including their filesystem and metadata records," the study found.
To produce the bicycle, layers of nylon were stacked on each other to create a single structure with the wheels, bearings and axle all made in one piece. The process means that a design can be created on a computer and then printed, removing the costly process of building prototypes. The use of advanced materials also allows manufacturing companies to build components that are much stronger and lighter because they do not have to be joined, welded or lathed.
Robin Southwell, chief executive of EADS UK, said: "We can now design a component on a computer and, just like printing a sheet of paper, we can print a product using just powder and lasers." Additive manufacturing has been around for several years but it has been possible to grow only relatively small products. However, 3D printers are becoming bigger and the process has become more sophisticated. Some of the world's largest manufacturing companies are looking at how they can use additive manufacturing to speed up product development and reduce waste. For EADS, the prize is to build aircraft components that are lighter and stronger than is possible using traditional processes.
