In today?s world of mobile computing with devices that fit in your pocket, the notion that the first computers ever made occupied entire rooms and weighed several tonnes is hard to remember. It seems almost ridiculous too. Weren?t they just in the imagination of Hollywood producers of B-grade science fiction movies? Nope, they were real, and the WITCH is back.

The WITCH computer became the ?world?s oldest original working digital computer? recently when a museum in the UK refurbished the machine and fired it up. The scene must have been akin to a cheesy sci-fi film since unlike today?s computers, the WITCH was beeping, flashing and clunking like nobody?s business. And it read software off paper tape with holes punched into it. The only thing it was missing was those magnetic tape reels, but alas, they appeared in later, more ?advanced? models.

The WITCH isn?t particularly useful anymore outside of its attraction as a museum piece. It can store 90 numbers, so it?s effectively a room-sized calculator. It used flashing valves instead of binary code to store numbers, and it could take five to ten seconds to multiply two numbers together. It was used in atomic research up until 1957 and then as a teaching device until 1973 when it was renamed the Wolverhampton Instrument for Teaching Computation from Harwell (ie WITCH!). In its time, the WITCH was only one of about a dozen state of the art computers in the world.

Given the WITCH was used for several decades without an upgrade, the mammoth computer marks a stark contrast with today?s computing devices which can be swapped out for an upgrade every 12 months (and in some cases even sooner). It would also be hard to see today?s devices working 60 years after their original build date. It can be easy to take our access to cheap computing technology for granted these days. It?s a great thing that a computer like the WITCH is still functioning since it?s a fascinating window into the beginnings of the computer age.

Euro Crisis Deal Struck: Euro Zone, IMF Reach Agreement On Long-Term Greek Debt


* EU-IMF reach agreement on cutting Greek debt-to-GDP level
* Aim is to reduce Greek debt to 124 percent of GDP by 2020
* Interest on loans to Greece to be cut, ECB profits returned
* Deal to include Greek debt buy-back
* Euro strengthens after word of a deal
By Jan Strupczewski and Annika Breidthardt
BRUSSELS, Nov 26 (Reuters) - Euro zone finance ministers and the International Monetary Fund clinched agreement on a new debt target for Greece on Monday in a breakthrough towards releasing an urgently needed tranche of loans to the near-bankrupt economy, officials said.
After nearly 10 hours of talks at their third meeting on the issue in as many weeks, Greece's international lenders agreed to reduce Greek debt by 40 billion euros, cutting it to 124 percent of gross domestic product by 2020, via a package of steps.
The deal should open the way for a major aid instalment needed to recapitalise Greece's teetering banks and enable the government to pay wages, pensions and suppliers in December. Greece could receive up to 44 billion euros, although it remains unclear if the full amount will be paid in one go.
To reduce the debt pile, the ministers agreed to cut the interest rate on loans to Greece and return 11 billion euros to Athens in profits from European Central Bank purchases of Greek government bonds on the secondary market.
They also agreed to help Greece to buy back its own bonds from private investors at an expected cost of around 35 cents in the euro, officials said.
European Central Bank President Mario Draghi said on leaving the talks: "I very much welcome the decisions taken by the minsters of finance. They will certainty reduce the uncertainty and strengthen confidence in Europe and in Greece."
Details of the agreement were to be announced at a news conference after the meeting ended.
The euro strengthened against the dollar after news of a deal was reported by Reuters.
"We've filled the financing gap until the end of programme in 2014," one official engaged with the talks said. A second official confirmed the figures.
Greek Finance Minister Yannis Stournaras said earlier that Athens had fulfilled its part of the deal by enacting tough austerity measures and economic reforms, and it was now up to the lenders to do their part.
"I'm certain we will find a mutually beneficial solution today," he said on arrival for the marathon talks.
Greece, where the euro zone's debt crisis erupted in late 2009, is the currency area's most heavily indebted country, despite a big "haircut" this year on privately-held bonds. Its economy has shrunk by nearly 25 percent in five years.
Negotiations had been stalled over how Greece's debt, forecast to peak at 190-200 percent of GDP in the coming two years, could be cut to a more sustainable 120 percent by 2020.
The agreed figure fell slightly short of that goal, and the IMF was still insisting that euro zone ministers should make a firm commitment to further steps to reduce the debt stock if Athens implements its adjustment programme faithfully.
The key question remains whether Greek debt can become sustainable without euro zone governments having to write off some of the loans they have made to Athens.
A source familiar with IMF thinking said the global lender was demanding immediate measures to cut Greece's debt by 20 percentage points of GDP, with a commitment to do more to reduce the debt stock in a few years if Greece fulfills its programme.
To reduce the debt to 124 percent by 2020, the ministers were putting together a package of steps including a debt buyback funded by a euro zone rescue fund, reducing the interest rate on loans and returning euro zone central bank 'profits' to Greece.
Germany and its northern European allies have so far rejected any idea of forgiving official loans to Athens.

DEBT RELIEF "NOT ON TABLE"
German Finance Minister Wolfgang Schaeuble told reporters that a debt cut was legally impossible, not just for Germany but for other euro zone countries, if it was linked to a new guarantee of loans.
"You cannot guarantee something if you're cutting debt at the same time," he said. That did not preclude possible debt relief at a later stage if Greece completed its adjustment programme and no longer needs new loans.
The source familiar with IMF thinking said a loan write-off once Greece has established a track record of compliance would be the simplest way to make its debt viable, but other methods such as forgoing interest payments, or lending at below market rates and extending maturities could all help.
The German banking association (BDB) said a fresh "haircut" or forced reduction in the value of Greek sovereign debt, must only happen as a last resort.
Two European Central Bank policymakers, vice-president Vitor Constancio and executive board member Joerg Asmussen, said debt forgiveness was not on the agenda for now.
The ministers agreed to reduce interest on already extended bilateral loans from the current 150 basis points above financing costs to 50 bps once Greece achieves a primary budget surplus of 4.5 percent of GDP.
Another option considered, which could cut Greek debt by almost 17 percent of GDP, was to defer interest payments on loans to Greece from the EFSF, a temporary bailout fund, by 10 years. It was not immediately clear if that had been agreed.
By forgoing profits on on its Greek bond portfolio, bought at a deep discount, the ECB could cut the debt pile by a further 4.6 percent by 2020, a document prepared for meeting showed.
Not all euro zone central banks are willing to forgo their profits, however, the German Bundesbank among them.
Before the meetings, officials had spoken of a 10 billion euro buy-back of Greek debt, that would achieve a net reduction of about 20 billion euros in the debt stock, although the potential gain has fallen as prices have risen since the idea was first mooted.

FORGIVING OFFICIAL LOANS?
German central bank governor Jens Weidmann has suggested that Greece could "earn" a reduction in debt it owes to euro zone governments in a few years if it diligently implements all the agreed reforms. The European Commission backs that view.
An opinion poll published on Monday showed Greece's anti-bailout SYRIZA party with a four-percent lead over the Conservatives who won election in June, adding to uncertainty over the future of reforms.
German paper Welt am Sonntag said on Sunday that euro zone ministers were considering a write-down of official loans for Greece from 2015, but gave no sources, and a euro zone official said such an option was never seriously discussed.

Wired SKorea to stem digital addiction from age 3

SEOUL, South Korea (AP) ? Park Jung-in, an 11-year-old South Korean, sleeps with her Android smartphone instead of a teddy bear. When the screen beams with a morning alarm, she wakes up, picks up her glasses and scrolls through tens of unread messages from friends, shaking off drowsiness.

Throughout the day, the gadget is in her hands whether she is in school, in the restroom or in the street as she constantly types messages to her friends. Every hour or so, she taps open an application in her phone to feed her digital hamster.

"I get nervous when the battery falls below 20 percent," Park said as she fiddled with the palm-size gadget. "I find it stressful to stay out of the wireless hotspot zone for too long."

In South Korea, where the government provides counseling programs and psychological treatment for an estimated 2 million people who cannot wean themselves from playing online computer games, youngsters such as Park have previously not been considered as potential addicts.

Here and in other parts of Asia, online addiction has long been associated with hardcore gamers who play online games for days on end, isolated from their school, work or family life and blurring the line between the real and fantasy online worlds. In a shocking 2010 case in South Korea, a 3-month-old girl died after being fed just once a day by her parents who were consumed with marathon online game sessions.

Park does not play computer games and in class, she confidently raises her hand to answer a question. She also gets along well with her friends and likes to cook as a hobby. And yet, she set off more than eight red flags on an addiction test, enough to be considered unhealthily dependent on her smartphone. Park is not unique and the government is concerned enough to make it mandatory for children as young as 3 to be schooled in controlling their device and Internet use.

Her obsession with being online is a byproduct of being reared in one of the world's most digitally connected societies where 98 percent of households have broadband Internet and nearly two thirds of people have a smartphone. Being wired is an icon of South Korea's pride in its state-directed transformation from economic backwater to one of Asia's most advanced and wealthy nations. Always seeking an edge, the government plans to digitize all textbooks from 2015 and base all schooling around tablet computers.

But some now fret about the effects that South Korea's digital utopia is having on its children, part of the first generation to play online games on smartphones, tablets and other devices even before they can read and write.

New mobile devices that instantly respond to a touch of a finger seem to make children more restless than before and lack empathy, said Kim Jun-hee, a kindergarten teacher who conducted an eight-month study on Internet safety and addiction education for pre-school children.

"Babies are in a stroller with a smartphone holder. Kids sit in the grocery shopping cart watching movies on the tablet computer," she said. "I've been teaching at kindergartens for more than 10 years now but compared to the past, kids these days are unable to control their impulses."

In Suwon city south of Seoul, students in teacher Han Jeoung-hee's classroom now turn in their smartphones when they arrive at school in the morning.

"Kids forgot to eat lunch, completely absorbed with smartphones and some stayed in the classroom during a PE class," said Han who teaches sixth grade students at Chilbo elementary school. Smartphones are put in a plastic basket and returned when kids leave for home after classes.

The National Information Society Agency, or NIA, estimates 160,000 South Korean children between age 5 and 9 are addicted to the Internet either through smartphones, tablet computers or personal computers. Such children appear animated when using gadgets but distracted and nervous when they are cut off from the devices and will forgo eating or going to the toilet so they can continue playing online, according to the agency.

Across the entire population, South Korea's government estimated 2.55 million people are addicted to smartphones, using the devices for 8 hours a day or more, in its first survey of smartphone addiction released earlier this year. Smartphone addicts find it difficult to live without their handsets and their constant use disrupts work and social life, according to NIA. Most of their personal interaction is carried out on the mobile handset. Overuse of smartphones may be accompanied by physical symptoms such as turtle neck syndrome caused by having the head in a constant forward position and a pain or numbness in fingers or wrists.

Though Internet addiction is not recognized as a mental illness, there is a growing call from medical practitioners and health officials worldwide to treat it as an illness rather than a social problem.

The American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders lists Internet Use Disorder as meriting further study. It is unclear whether it will be recognized as a mental illness in a major revision of the standard-setting manual due out next year. But as the Internet becomes more pervasive and mobile, more societies are grappling with its downside. In Asia, countries that have experienced explosive growth in the Internet such as Taiwan, China and South Korea are most active in carrying out research into whether Internet addiction should be recognized as a mental illness, according to Lee Hae-kook, a psychiatry professor at Catholic University of Korea, College of Medicine.

South Korea already provides taxpayer-funded counselors for those who cannot control their online gaming or other Internet use. But the emergence of the smartphone as a mainstream, must-have device even for children is changing the government's focus to proactive measures from reactive.

South Korea's government is widening efforts to prevent Web and digital addiction in school-age children and preschoolers. Starting next year, South Korean children from the age 3 to 5 will be taught to protect themselves from overusing digital gadgets and the Internet.

Nearly 90 percent children from that age group will learn at kindergartens how to control their exposure to digital devices and the danger of staying online for long hours. The Ministry of Public Administration and Security is revising laws so that teaching the danger of Internet addiction becomes mandatory from pre-school institutions to high schools.

Kim, the kindergarten teacher, said educating children against digital and web addiction should start early because smartphones are their new toys.

From next year, her program for 3-year-olds will focus on introducing them to the positive activities they can do with the computers, such listening to music. Children aged 4 and 5, will learn the dangers of overuse and how to control their desire to use computers.

Programs also include making and learning the moves for "computer exercises" and singing songs with lyrics that instruct kids to close their eyes and stretch their bodies after playing computer games. They read fairy tales where a character falls prey to Internet addiction and learn alternative games they can play without computers or the Internet.

Kim said parents have to be involved in the education. One of the pledge cards written by a 5-year-old girl reads: "I promise to play Nintendo for 30 minutes only. Daddy promises to play less cellphone games and play more with me."

UN nuclear agency reports being hacked

(AP) ? The International Atomic Energy Agency acknowledged Tuesday that one of its servers had been hacked after a previously unknown group critical of Israel's undeclared nuclear weapons program posted contact details for more than 100 experts working for the U.N. nuclear watchdog.

A group called "Parastoo" ? Farsi for the swallow bird and a common Iranian girl's name ? claimed responsibility for posting the names on its website two days ago.

Israel is commonly acknowledged to possess nuclear weapons but has neither confirmed or denied its status. It says Iran is secretly working to make nuclear arms ? something Tehran denies ? and describes the Islamic republic as the greatest threat to the Mideast. But Iran and Arab countries say the Jewish state's nuclear capacities pose the greatest menace.

Chastising Israel for its "nuclear arsenal," the hackers urged the experts whose names they published to sign a petition demanding an "open investigation" into Israel's nuclear program.

IAEA spokeswoman Gill Tudor said the agency "deeply regrets this publication of information stolen from an old server." She said the server had been shut down some time ago and agency experts had been working to eliminate any "possible vulnerability" in it even before it was hacked.

The IAEA was doing "everything possible to help ensure that no further information is vulnerable," she said in an email.

Millwards Matt looking to upset Farkland Tyson in Jem Racing Super Paws (Heat 3)

Millwards Matt will be looking to surprise his opponents in the Jem Racing Super Paws (Heat 3) at Poole in England on Tuesday, November 27, 2012. He made his debut this year, but has proven that he possesses the ability to deliver positive results at this level with consistency.

Most of the runners lined up for action in the Grade OR event have been struggling for consistency recently, which means that the competition will be a close one at the end of the day.

However, this will give a solid opportunity to some of the least favourite hounds to cause an upset in order to make a name for themselves and bag a cash prize of ?100. The spectators will be eagerly awaiting the start of action at 21:22 GMT.

According to the bookmakers, the best chances of victory are with Farkland Tyson, despite the fact that he does not have a lot of experience. He is learning with the passage of time, but needs to start challenging the best in the business in order to get the attention of the bettors regularly.

The P. Chatfield?s trained hound started off his career in 2012 with an outing in a Grade GR contest. This was probably too tough for him, but he did not choke under pressure at all. He was up against some very good runners and finished on top of the table in the end.

Since then, he has been running at Poole and his performances have been really impressive. He is a hard worker and knows how to handle pressure. However, he has never appeared in a Grade OR contest in the past, which means that things will be a bit tough for him today.

He completed a hat-trick of victories in lower classes recently and will be looking to carry that positive momentum into today?s race as well.

On the other hand, Millwards Matt finished in a disappointing sixth place last time around in this class. He was unable to cause any problems for his opponents, thus will be under immense pressure right now.

Therefore, the P. Young?s trainee will have to be at his best in order to be competitive at Poole.
