'Friendly' drone on dog leash takes off

Drones are becoming more common in our skies, performing a variety of tasks, from taking photos to monitoring crops and potentially even delivering broadband.
But there are strict rules about their usage, which has led some to come up with innovative ways to fly such vehicles more safely.
"I'm using a dog leash for a small dog," says roboticist Sergei Lupashin as he demonstrates a new kind of consumer-friendly drone at the Ted (Technology, Entertainment and Design) conference in Vancouver.
By tethering it, he hopes the Fotokite, as it is called, can avoid some of the issues faced by unmanned aerial vehicles (UAVs), which are banned without a special licence because of safety and privacy concerns.
"It doesn't rely on GPS [ Global Positioning System], sophisticated machine vision, radio, it doesn't even use a compass. Most crashes today happen because of GPS, radio or piloting issues," says Dr Lupashin.
"Should something happen, the leash gives a robust fail safe - the vehicle reduces thrust and it automatically comes back to the operator," he adds.
The inspiration for the device came during street protests in Bolotnaya Square in Moscow, when he realised it could be an invaluable tool for reporting protests around the world.
"For journalists it is good to get that perspective, to show the scale of the event without adding to the tension," says Dr Lupashin.
But he also sees potential for amateur and professional photographers, archaeologists, architects and even as a toy for children.
His prototype device uses a shop-bought quadrocopter with "a basic action camera attached" which, in turn, is connected to a standard dog lead. It can shoot both video and stills.

'Game of Thrones': Who did it?

Fresh on the heels of the infamous Red Wedding, Sunday's "Game of Thrones" served up more murderous matrimony. But, with what fans have dubbed the "Purple Wedding," many of us finally got something we'd been hoping for since season one.
'Thrones' is back: 'All men must die'

Sex, dragons fuel new 'Thrones' tease
As the loathsome King Joffrey lay on the ground doing his best impersonation of Violet Beauregarde from "Willy Wonka & the Chocolate Factory," one question sprung to mind after the obligatory high fives: Who did it?
Certainly there is no shortage of folks who would have loved to off the sadistic, smug boy king. Here, we run down some of the key suspects and why they may have been behind the deadly deed. Let us know your theory in the comments (and, book readers, no spoilers, please!)
Tyrion
He's obviously Cersei's top suspect. And it's not like he doesn't have reasons.
There was no love lost between Tyrion and his nephew (remember the much-celebrated slap?) even before Joffrey went out of his way to humiliate him repeatedly, both before and after the wedding.
Slicing up his gift of a rare and priceless book? Check. Wine on the head? Check. Trying to force him into a humiliating performance at the feast? Check.
Was it all just too much for Tyrion? Not hard to imagine.
Sansa
And then there's Tyrion's wife. Joffrey was responsible for the deaths of her father, mother and brother. And that's on top of having her publicly beaten and tossing her aside for a more politically useful marriage. (Not that she wanted anything to do with him by that point.)
Sansa may be as close to an innocent as still exists in King's Landing. But what better time than Joffrey's wedding day to exact some revenge?
Oberyn Martell
"The Lannisters aren't the only ones who pay their debts."
When the Martells sent fiery warrior Oberyn to the wedding in place of his brother, Prince Doran, it was a not-so-subtle hint that they haven't forgotten, or forgiven, that Oberyn's sister, Elia, was raped and killed by Gregor "The Mountain" Clegane, who serves the Lannisters.
It only took hearing a Lannister song, "The Rains of Castamere," to send Oberyn into an anti-Lannister stabbing fit at a brothel. Was murdering Joffrey his plan all along?
The Tyrells

The wedding was over. Margaery was a queen. But Margaery and the rest of the Tyrell family, particularly Margaery's grandmother Olenna, had no doubts about what a rotten little bastard (literally) Joffrey was.
It's possible they've concocted a scheme to off Joffrey, but still press their claim for the Iron Throne now that Margaery has a crown on her head.
Stannis and Melisandre
As Jaime told Joffrey, the war is not over.
We assume Joffrey's transition to a lovely shade of purple was due to poisoning. But could it have been more dark magic from the Red Priestess instead?
It's easy to focus on the people who were at the wedding. But we've already seen what Melisandre can do to a foe without having to be in his presence. Could this have been an otherworldly announcement that Stannis is down, but not out?
Somebody else?
Seriously, who doesn't have one reason or another to want Joffrey dead?
Lord Varys isn't called "The Spider" for nothing. He's sneaky, as well as professing to be the only person in Westeros who truly wants what's best for the kingdom. He could have decided that's not Joffrey.
Knight-turned-fool Ser Dontos was obviously up to something. Was this part of a plan to save Sansa and avenge his humbling by Joffrey?
It's hard to imagine how Daenerys could have played a part from across the Narrow Sea. But could someone loyal to the Targaryens have made a move to weaken the Lannisters' hold on the throne?
We can presume it will all become clear in time. Meanwhile, we'll make a mental note to never, ever, accept a wedding invitation in Westeros.

What Not To Say In A Job Interview



Setting yourself apart from the crowd is vital when you are looking for that new job. This applies for all stages of the recruitment process - you want to ensure that your CV is at the top of a recruiter or hiring manager’s pile, and that your interview shows you in the best possible light.
People looking to fill a role will be looking for that something special which sets the very best candidates apart. To give yourself the best opportunity, here are some very common mistakes and phrases which you should try to avoid in those all-important interviews

I don’t know
Interviewers will be looking to stretch and challenge candidates during the course of the recruitment process. The best way of dealing with the tough questions is to do your homework. The importance of research cannot be understated – you should know about the company, and be prepared for anything you will be asked about your own CV. Of course if there is a question which you are not expected to know the answer to, or if you are genuinely stuck, don't make things up or try to bluff your way through. Move back into your comfort zone, relate the question back to something you do know and take on board any new information you are given. But as I said, proper planning and preparation is essential.

What’s the salary?
The salary is always a tough point to discuss with a new employer, especially at the interview stage. There is a time and place to bring it up, and the first interview isn't always the right one. At the same time, you don’t want to get too far down the process and not know what the salary is. Initially you should have a good indication of the remuneration from the job description. The chances are that the interviewer themselves will ask you what sort of salary you are looking for - this gives you the opportunity to talk about it and negotiate the best deal for you.

How many holidays do I get?
Companies are on the look-out for people that are motivated and willing to put in the necessary effort. They want staff to be ambitious, driven self-starters, not people who are just looking for an easy life. If you want a fulfilling career and the rewards that tend to come with that, then you have to be prepared to go that extra mile. Of course you are perfectly entitled to perks, but try to avoid talking about things like holiday entitlement straight away, because it can give off the wrong impression.

I dislike my current company
You never want to turn the tone of the interview negative, even if you may be having a bad experience at your current job. All this does is make you seem like somebody who is difficult to manage. If asked why you are leaving, focus more on your ambitions for the future and what excites you about the job you are applying for.

I don’t have any questions
I have written before about candidates needing to ask questions themselves in interviews. You want to show prospective employers how keen you are to get the role. The research you have done may have thrown up some interesting facts that you can ask about, or you may want to know about the scope for personal development. You may also wish to get some more information about your role or the working culture – either way it is important that the interview process is not one sided.

Holy Week 2014

To Use, Or Not To Use The Cane


There were tempers flaring in the home of Demola Lewis, his parents threatening a police arrest, when he returned home from school with bruises gotten from a teacher’s cane recently. Demola, 14, a Junior Secondary three student of Government High School, Ipetumodu, told his parents he got beaten by his teacher for engaging in a fight with another student.
But for his father, Mr Lewis, no offence should warrant the extent of beating gotten from his teacher which was evident from the bruises on his son’s body. “I am not saying they should not correct my child, but this is too much,” he complained. “I don’t even beat my son to the extent of giving him bruises on his body so what right does a teacher have to beat my son like that?”
An outdated practice?
The use of a cane as a means of correcting or instilling discipline in a child by teachers and school administrators has been a topic of debate among several interest groups more than a few times. While many would say the choice of using a cane should be left for the parents or guardians alone, others say a cane should not be used either at home or in school for any reason.
Several people still fall under the school of thought that if you spare the rod, you end up spoiling the child. For them, a cane can be used by any older or matured person, in school or at home, to correct a child immediately so that he would not repeat the same wrong doing again.
Among the latter group who believe in the cane comes the question – to what extent should the cane be used in schools?
In most private schools in Nigeria today, the use of a cane has been completely abolished, forbidden some would say. For some of these schools, the adopted British or American curriculum being used to train the students does not conform with the use of a cane. Others have stopped using it or decided not to use it as a result of decisions made by the parents or school administration. The cane is mostly being used, however in scanty measures, by public school teachers today.
Schools without canes
Belinda Amao, the Head Teacher of Chrisland School, Ikeja, while speaking about the use of cane at a school function recently, said it was stopped because the management realised that it affects the relationship between the teacher and the students negatively.
“We realised that when a teacher uses the cane on a child, the child becomes withdrawn and would not be able to approach the teacher when he or she has problems with studies,” she said. “This could affect the child’s performance.”
At Bright Stars International School, Apapa, the use of cane was stopped after an unanimous decision was reached by the parents during one of the Parents Teacher’s Association meetings. “All the parents said they would prefer if the teachers stopped using the cane, so we had to oblige,” said Patricia Chukwuemeka, Head Mistress of the school.
Breaking the law
In 2011, the Lagos State Government passed a legislation which outlawed the caning, beating or physical torture of school students. The provision of the law stated that striking any adult person with a stick or other weapon constitutes a violent criminal offence statutorily classified as Felony Assault and Battery, for which jail sentences can be imposed after a fair trial, under Nigerian law.
However, Ajoke Osoba, an English teacher at Oshodi Senior High School, Oshodi, is one woman who doesn’t agree with the law. “I don’t beat them because I hate them, I beat them to discipline them just like I beat my own children and it always works,” she said, adding that she only beats her students on the palm and no other part of the body.
The parents’ view on the use of the cane is just as varied.
Caroline Paul, a mother of two said she has never used a cane on any of her children and would never allow a teacher beat her children with a cane. “One of the things I asked when I was looking for a school for my children is whether they use cane on the students,” she recalled. “I don’t believe in the cane and I was not brought up with it. There are other ways of disciplining a child.”
Tomisin Bakare, another mother believes the cane should only be used at home and not in school because “teachers can sometimes get too overzealous.”
But Taiwo Oyedele, a counselor and director of Children In Leadership Foundation, says that most Nigerian parents today are being misled by the Western culture. For him, you cannot use western methods to train an African child or African methods to train a western child.
“Most parents are just deceiving themselves these days,” he said. “What works abroad might not necessarily work here. I don’t believe a cane should be used at school but it should be used at home. A child who is not properly trained according to the dictates of the society in which he grows up would always misbehave later in life.”
