Welcome to the Drone Age
THE scale and scope of the revolution in the use of small, civilian drones has caught many by surprise. In 2010 America's Federal Aviation Authority (FAA) estimated that there would, by 2020, be perhaps 15,000 such drones in the country. More than that number are now sold there every month. And it is not just an American craze. Some analysts think the number of drones made and sold around the world this year will exceed 1 million. In their view, what is now happening to drones is similar to what happened to personal computers in the 1980s, when Apple launched the Macintosh and IBM the PS/2, and such machines went from being hobbyists' toys to business essentials.
That is probably an exaggeration. It is hard to think of a business which could not benefit from a PC, whereas many may not benefit (at least directly) from drones. But the practical use of these small, remote-controlled aircraft is expanding rapidly. These involve areas as diverse as agriculture, landsurveying, film-making, security, and delivering goods. Other roles for drones are more questionable. Their use to smuggle drugs and phones into prisons is growing. Instances have been reported in America, Australia, Brazil, Britain and Canada, to name but a few places. In Britain the police have also caught criminals using drones to scout houses to burgle. The crash of a drone on to the White House lawn in January highlighted the risk that they might be used for acts of terrorism. And in June a video emerged of a graffito artist using a drone equipped with an aerosol spray to deface one of New York's most prominent billboards.
How all this activity will be regulated and policed is, as the FAA's own flat-footed response has shown, not yet being properly addressed. There are implications for safety (being hit by an out-of-control drone weighing several kilograms would be no joke); for privacy, from both the state and nosy neighbours; and for sheer nuisance—for drones can be noisy. But the new machines are so cheap, so useful and have so much unpredictable potential that the best approach to regulation may simply be to let a thousand flyers zoom.

How music is the real language of political diplomacy
Forget guns and bombs, it is the power of melody that has changed the world

An old man plays his cello at the foot of a crumbling wall. The notes of the sarabande of Bach’s Suite No 2 rise in the cold air, praising God for the “miracle” of the fall of the Berlin Wall, as Mstislav Rostropovich later put it. The photograph is seen around the world. The date is 11 November 1989, and the Russian virtuoso is marching to the beat of history.
Publicity stunt or political act? No doubt a bit of both – and proof, in any case, that music can have a political dimension. Yo-Yo Ma showed as much in September when the cellist opened the new season of the Philharmonie de Paris with the Boston Symphony Orchestra. As a “messenger of peace” for the United Nations, the Chinese American is the founder of Silk Road Project, which trains young musicians from a variety of cultures to listen to and improvise with each other and develop a common repertoire. “In this way, musicians create a dialogue and arrive at common policies,” says analyst Frédéric Ramel, a professor at the Institut d’Études Politiques in Paris. By having music take the place of speeches and peace talks, the hope is that it will succeed where diplomacy has failed.[…]
Curiously, the study of the role of music in international relations is still in its infancy. “Historians must have long seen it as something fanciful, because history has long been dominated by interpretations that stress economic, social and political factors,” says Anaïs Fléchet, a lecturer in contemporary history at the Université de Versailles-St-Quentin and co-editor of a book about music and globalisation.
“As for musicologists,” she adds, “until quite recently they were more interested in analysing musical scores than the actual context in which these were produced and how they were received.” In the 1990s came a cultural shift. Scholars were no longer interested solely in “hard power” – that is, in the balance of powers and in geopolitics – but also in “soft power”, where political issues are resolved by mutual support rather than force.

Since then, every embassy has a cultural attaché. The US engages in “audio diplomacy” by financing hip-hop festivals in the Middle East. China promotes opera in neighbouring states to project an image of harmony. Brazil has invested in culture to assert itself as a leader in Latin America, notably by establishing close collaboration between its ministries of foreign affairs and culture; musician Gilberto Gil was culture minister during Luiz Inácio Lula da Silva᾽s presidency from 2003 to 2008. He was involved in France’s Year of Brazil. As Fléchet recalls, “the free concert he gave on 13 July, 2005 at the Place de la Bastille was the pinnacle. That day, he sang La Marseillaise in the presence of presidents Lula and Jacques Chirac.” Two years earlier, in September 2003, Gil sang at the UN in honour of the victims of the 19 August bombing of the UN headquartes in Baghdad. He was delivering a message of peace, criticising the war on Iraq by the US: “There is no point in preaching security without giving a thought to respecting others,” he told his audience. Closing the concert, he invited then UN secretary general Kofi Annan on stage for a surprise appearance as a percussionist. “This highly symbolic image, which highlighted the conviction that culture can play a role in bringing people together, shows how music can become a political language,” Fléchet says.

A design pattern is often posed as a question: how do we solve some design problem? However a design problem is, by its nature, nonspecific, and rarely has a single straight-forward answer. There might be several ways to solve the same problem, some better than others depending on the specific situation and the specific context of the problem. A design pattern is intended to share not just solutions but a better understanding of both the problem and how it might be solved. Firstly, patterns have a well-defined structure. This consistent layout makes it easy to browse through a collection of patterns to find relevant help and then dive further into the material. The structure encourages the author of the pattern to think carefully about the knowledge they're sharing, whilst making the material more consistently accessible to a reader.

Smart Greenhouse
Control the light, watering, temperature, and humidity of your greenhouse – automatically.
Kevin Farnham
Smart Greenhouse, one of three professional category winner in the 2014 IoT Developer Challenge, is an Internet of Things (IoT) device and application that monitors and controls a greenhouse environment. The concept for Smart Greenhouse came into being after the core team – Dzmitry Yasevich, Pavel Vervenko, and Vladimir Redzhepov – attended JavaOne Russia in April 2013. There, the team saw presentations of a smart house, various robots, and other devices, all controlled by Java.
Yasevich notes, “We were impressed by these solutions and had an idea to do something like that. Pavel Vervenko suggested making an automated greenhouse. Everyone liked the idea!”.
First, the team selected the hardware. “We started to use Raspberry Pi as a basis”, Yasevich says. “It is a compact but fullfedged computer with 700 MHz and memory at 512 MB. This system costs around $35”.
However, early on, a safety concern arose. “Current under high voltage passes in the greenhouse, and there is an automatic watering system, so it was necessary to properly consider all the aspects related to insulation”, Yasevich says.

Saint Patrick's Day, also known as The Feast of Saint Patrick, is a traditional holiday celebrated every year on March 17th, the day the patron saint of Ireland, Saint Patrick, died.
Patrick, who was born in the fourth century, lived in the British Isles, a land that had been invaded and conquered first by the Romans and then by Germanic tribes. At the age of 16, Patrick was captured and taken as a slave from the British Isles to what is now Ireland. He lived there for several years herding sheep. He was a religious boy, and he prayed that he would someday return to his homeland.
Legend has it that one night while he was praying, a voice told him to escape from the farm, and find a ship that was waiting for him in a harbor two hundred miles aways. Patrick got to the ship, sailed to Europe, and disembarked in what is now probably France. He ---1--- several of the ship's crew through a dangerous forest, praying all the time. Neither Patrick nor any member of his crew was captured. When some of the men were about to die of starvation, wild animals appeared to them to eat. Events such as these appeared to be miracles and gave rise to later legends surrounding Patrick.
Finally finding his way home, Patrick felt that he was called by God to perform an important mission. He believed it was his duty to go back to Ireland and convert the Celtic people to the Christian Religion.
Patrick arrived in England and became a missionary, traveling from village to village and talking about his faith. Once, several members of a tribe approached Patrick and told him that they found it difficult to understand and believe in the Holy Trinity. Patrick thought a moment, then stooped down and picked one of the plentiful shamrocks growing wild around Ireland. “Here are three leaves", he said, “yet it is one plant. Imagine the Father, Son and the Holy Spirit as each of these leaves. Here they are, yet they are one plant." The tribesmen understood, because Patrick had used a familiar object to explain. From that time on, the shamrock has been a revered symbol of Ireland.
There are lots of stories about Patrick. One of them is about him forcing snakes out of the entire country of Ireland. Even though there are many different stories about how he accomplished such a task, it is probably not true. Patrick died on March 17th, and the Irish people set aside the day to mourn. He became the patron saint of Ireland. Mourning turned to commemorating him and celebrating his life.
Because of Saint Patrick, lots of cities around the world with a large population of Irish have parades. Green is one of the national colors of Ireland. Green stripes are painted on the streets where the parade will travel. People wear green shirts, ties, hair ribbons, and hats. There are even pubs which serve green beer on that day.
Saint Patrick's Day was made an official Christian holiday in the early seventeenth century. It is now observed by the Catholic Church, the Anglican Communion, the Eastern Orthodox Church and Lutheran Church. The day commemorates Saint Patrick and the arrival of Christianity in Ireland. Not only that, but it also celebrates the heritage and culture of the Irish in general.

Self-repairing software tackles malware
University of Utah computer scientists have developed software that not only detects and eradicates never-before-seen viruses and other malware, but also automatically repairs damage caused by them. The software then prevents the invader from ever infecting the computer
again.
A3 is a software suite that works with a virtual machine - a virtual computer that emulates the operations of a computer without dedicated hardware. The A3 software is designed to watch over the virtual machine's operating system and applications, says Eric Eide, University of Utah research assistant professor of computer science leading the university's A3 team with U computer science associate professor John Regehr. A3 is designed to protect servers or similar business-grade computers that run on the Linux operating system. It also has been demonstrated to protect military applications.
The new software called A3, or Advanced Adaptive Applications, was co-developed by Massachusetts-based defense contractor, Raytheon BBN. The four-year project was completed in late September.
There are no plans to adapt A3 for home computers or laptops, but Eide says this could be possible in the future.
"A3 technologies could find their way into consumer products someday, which would help consumer devices protect themselves against fast-spreading malware or internal corruption of software components. But we haven't tried those experiments yet," he says.
Unlike a normal virus scanner on consumer PCs that compares a catalog of known viruses to something that has infected the computer, A3 can detect new, unknown viruses or malware automatically by sensing that something is occurring in the computer's operation that is not correct. It then can stop the virus, approximate a repair for the damaged software code, and then learn to never let that bug enter the machine gain.
While the military has an interest in A3 to enhance cybersecurity for its mission-critical systems, A3 also potentially could be used in the consumer space, such as in web services like Amazon. If a virus or attack stops the service, A3 could repair it in minutes without having to take the servers down.

“Dear Robert,
I can’t believe I have found your email address, because I thought I’d lost it! It’s been so long we haven’t talked, I feel I have so much to tell you. Do you remember Alex from our high school class? We got married! And we’ve been married for about six years. We have two kids, Lily and Oliver. They’re so lovely! Lily is five and Oliver is two. We moved from Florida right after we had Lily for Alex got a nice job as a chief engineer of a car factory in Chicago and we’ve been living here since then. Chicago is an incredible city. There are many shopping centers, parks, libraries and the nightlife is pretty fun. Of course, after having two kids, Alex and I don’t have plenty of time to go out at night, but we do catch a movie every once in a while, we just have to find a babysitter! I’m still working as a teacher in a primary school very close to our neighborhood. I work in the afternoons and it gives me the opportunity to see the kids in the morning and at night. Alex usually works all day, yet he gets home before I do, so that when I arrive the kids have already taken their showers and are finishing their supper. It’s very rewarding to be a mom, even though I may get worn out at times. So, I heard you run a taco place in central Florida, is that right? Me and my husband love Mexican food and we’re planning on visiting our parents in the city on Thanksgiving. Maybe we could stop by your business and grab a taco! Well, Oliver has just woken up from his afternoon nap and is calling for me! I’m looking forward to hearing from you soon!
Love,
Lucy”

E-mail Spoofing
E-mail spoofing is the forgery of an e-mail header so that the message appears to have originated from someone or somewhere other than the actual source. Distributors of spam often use spoofing in an attempt to get recipients to open, and possibly even respond to, their solicitations. Spoofing can be used legitimately. However, spoofing anyone other than yourself is illegal in some jurisdictions.
E-mail spoofing is possible because Simple Mail Transfer Protocol (SMTP), the main protocol used in sending e-mail, does not include an authentication mechanism. Although an SMTP service extension (specified in IETF RFC 2554) allows an SMTP client to negotiate a security level with a mail
server, this precaution is not often taken. If the precaution is not taken, anyone with the requisite knowledge can connect to the server and use it to send messages. To send spoofed e-mail, senders insert commands in headers that will alter message information. It is possible to send a message that
appears to be from anyone, anywhere, saying whatever the sender wants it to say. Thus, someone could send spoofed e-mail that appears to be from you with a message that you didn't write.
Although most spoofed e-mail falls into the “nuisance" category and requires little action other than deletion, the more malicious varieties can cause serious problems and security risks. For example, spoofed e-mail may purport to be from someone in a position of authority, asking for sensitive data, such as passwords, credit card numbers, or other personal information – any of which can be used for a variety of criminal purposes. One type of e-mail spoofing, self- sending spam, involves messages that appear to be both to and from the recipient.

I. “Six months ago, saving Libya from potential atrocities inspired by Moammar Gadhafi meant establishing a no- fly zone over the country, all the better to protect Benghazi, the rebel stronghold in the east. ____________ classic mission creep set in and the NATO forces, Canada among them, were bombing Tripoli and clearly trying to eliminate Africa’s longest-standing dictator and his sons (while denying that was the goal).”
II. “Like all early civilisations Ancient Greece was an agricultural society. Most of the people lived by farming and the main form of wealth was owning land. In each city there was an upper class and a middle class of men like substantial farmers, doctors and teachers. ____________ the vast majority of people were peasants and craftsmen or slaves. Slavery was common. (It is estimated that about 30% of the population of Athens was made up of slaves). If they worked in rich peoples homes slaves could be reasonably treated. However by law owners were allowed to flog slaves. Those slaves who worked in mines probably suffered the most.”
III. “Older people are facing a scarcity of qualified nurses to care for them ____________ the Government changes its policy on undergraduate education, a leading nursing organisation has warned. The All-Ireland Gerontological Nurses Association (AIGNa) is calling for the urgent introduction of specialised nursing degree courses in care for older people – as an estimated 700 jobs remain unfilled in the sector.”

This is not a great time to be a recent college graduate.
Average student-loan debt is $29,400. The underemployment rate is 44 percent for graduates ages 22 to 27, meaning they are holding jobs that don’t require bachelor’s degrees. And the average age of financial independence for college graduate these days is 30.
Such statistics have given rise to the narrative that a college degree is no longer worth it, although volumes of economic studies on lifetime earnings prove otherwise. Even so, given the number of college graduates struggling to launch their careers, a wide gap has emerged between what the workforce needs in employees and what colleges are producing in graduates.
Part of the problem is that we have high expectations for the bachelor’s degree today. Thirty years ago, when fewer people required a higher education to get ahead in life, the bachelor’s degree was seen as a vehicle for broad learning. The training part came later by going to graduate school or getting a job where the new employer trained you.
Now we demand that skills training move in tandem with broad learning, and expect both to be completed in the four years of an undergraduate education. For too many students, however, the bachelor’s degree is not providing that dual experience - high-impact, in-classroom learning and out-of-the- classroom, experiential, and hands-on learning necessary for success in today’s economy.
Because of student loan debt, graduate or professional school is no longer an option for many recent college graduates. They’re searching for quick and cheap add- on boot camps that give them what they’re missing. And a whole new set of providers are emerging outside of the traditional higher-education ecosystem to provide that lift.
Last year, General Assembly, which offers courses of a few hours to a few weeks in everything from digital marketing to web development, expanded to Washington, DC, where it is selling out of nearly all of its offerings. Its average student is in his mid-20s and just a few years out of college.
