By Kevin CurranIEEE Technical Expert So, for all you out there with similar sensitivities planning to go and see Skyfall, the latest in the Bond franchise, be warned! I have been to see this movie (expect spoilers below) and if you like your technology on the realistic side then you should see a different show... One of the most glaring errors occurs in what is perhaps the most crucial scene between the cyber-terrorist bad guy Raoul Silva, played by Javier Bardem, and Bond, who is tied up throughout to a chair. In the scene, the large room is dominated by the racks of computers that allow Silva to conduct his cyber-attacks. What is striking to a geek like me however is the complete absence of background noise! Firstly, a room full of computing hardware would have to be air-conditioned to keep the temperature of the servers down. Despite the precarious situation Bond was in, all I could think about was the potential of a fire caused by overheating throughout this scene. Secondly, as anyone who has been in a server farm will tell you, you would have struggled to hear the conversation over the background humming from the machines themselves. Hacked-off Later we see an active hacking attempt on MI6 by Silva with Q and Bond watching an animation that represents the code involved in the attack. The animation is very creative but it has absolutely no resemblance to anything you might see in reality. What you would actually see would be a plain command line - very dull admittedly. If you were very lucky you might have a mirror image of the attacker's screen but clever graphics? Not likely. Again, we security geeks are asked to suspend our knowledge of the complexities of cryptography when we find Bond being able to decipher part of the code in order to spot Granborough Road Tube station embedded in the cipher. If only it was as easy as that. Code-breaking is incredibly difficult, just ask the poor people at GCHQ who only last week had to admit they were stumped by a 70-year-old message taped to the leg of a dead pigeon, and can really only be done nowadays by large amounts of computing power. I cannot remember the last time I broke even a simple substitution code, but admittedly I don't work for GCHQ. Tracking shots Then there is my particular bugbear - tracking Bond underground. The public have no idea how hard it is to even track people in indoor locations using radio frequency techniques such as wi-fi, Bluetooth or Zigbee. It is highly unreliable. However difficult normal above-ground indoor tracking can be, tracking people underground is a nightmare. Despite this, we see Q getting an immediate fix on Bond and easily tracking him as he navigates deep underneath London in the tunnels. Arrhhhh, I'm an indoor location determination researcher... get me out of here! Of course, it is not difficult to understand why films overreach in their depiction of technology. Take just one example from Skyfall, such as hacking. Hacking in the real world is quite mundane and involves a number of labour intensive steps from identifying the systems which have weaknesses to executing the "payloads" which allow capture of the remote systems. It also quite often takes place on an old-fashioned "command line" with no fancy graphics at all. Any movie which attempted to give you a realistic interpretation of this would risk putting the audience to sleep. Licence to school The positive aspect for us involved in teaching computer science is that exciting overdramatisation of technology can encourage the younger generation to take up computing courses in higher education. Even without the movie glamour however, life in computer sciences can be pretty exciting. One of the most involving aspects of my life is acting as an expert witness for defence lawyers in court cases. This often sees me forensically trawling through a defendant's hard disk or mobile phone in some corner of a police station, visiting suspects in prison and attending court in order to help with technical questions. This is indeed a fast-paced world to be in, and one about to get even more interesting in the near future due to the sheer amount of information stored on digital devices. The importance of this data and the need for secure systems is certainly one aspect of technology that Skyfall did get right - the James Bonds of the future will have to be very aware of the potential for disruption posed by hacking sensitive information and platforms. Kevin Curran is a technical expert for internet and security matters at the Institute of Electrical and Electronics Engineers (IEEE), and is also a reader in computer science at the University of Ulster.
Viewpoint: James Bond fails the tech test in Skyfall

By Jeremy McDermottBBC News, Medellin Not now. The presidential election on 30 May is set to be a photo finish. "It was only 70 days ago that Colombia thought that Uribe was going to be the next president," said Rafael Pardo, the Liberal Party candidate. "Now the country faces a dilemma: a continuation of Uribe's politics or a fresh start." All the polls indicate that the contest will go to a second round on 20 June, with most suggesting that Antanas Mockus of the Green Party will face Mr Santos in the second ballot. This is hard to understand when one thinks that President Uribe still has approval ratings of 60% after almost eight years in power. His popularity can largely be attributed to his hard-line, US-backed security policies. He has had great success. Marxist rebels, engaged in conflict with the Colombian state for more than four decades, have been driven deep into their mountain and jungle stronghold, their numbers halved. Drug production is down and the brutal right-wing paramilitary militias have demobilised. Mr Uribe pushed for a referendum on whether the constitution should again be change to allow him to stand for a third term. But on 26 February, the Constitutional Court banned any further re-election and Mr Santos launched his bid for the presidency. Split field President Uribe has been unable to transfer his popularity to Mr Santos, 58, or the unified political base with which he has governed. The main pro-Uribe parties, the Conservatives, Cambio Radical and Mr Santos' Partido de la U, are all fielding their own candidates. "The Uribe government has been successful, nobody can deny that," said Maria Victoria Llorente of the Bogota-based think-tank Fundacion Ideas para la Paz. "However it came at a cost, the dark side of the administration: paramilitarism, human rights abuses and illegal wiretapping. Santos is associated with this." Mr Santos has inherited a series of scandals which are tainting him far worse than they have the president. The one that he had to shoulder as defence minister is that of the "false positives". Within the army there was a "body bag" culture. Success was measured by the number of enemies killed in combat. So some units of the army began to round up civilians, initially homeless people, who would turn up dead in remote parts of the countryside in rebel uniform, presented as guerrillas killed in combat. Last year evidence emerged that unemployed men in the slums of Bogota were being offered work in the eastern province of Norte de Santander only to turn up dead, allegedly killed in combat with the army. Now the attorney general's office is investigating more than 1300 cases of "false positives" involving more than 2,000 victims. Pencil Another scandal has been that of the secret police, the DAS, which answers to the president. Some DAS members have admitted that there were illegal intercepts of telephone calls by senior magistrates, opposition politicians and journalists. Mr Uribe has denied that he ordered the wire-tapping, but investigations are closing in on members of his inner circle in the presidential palace. Hence the appeal of Antanas Mockus, 58, twice mayor of Bogota, who promises to break with past political corruption. The idea is intoxicating for Colombians tired of scandals and endemic corruption and this is reflected in his extraordinary and rapid rise in the polls. Mr Mockus carries with him a pencil everywhere he goes on the campaign trail. It has become the symbol of his campaign. "The next chapter of Colombia's history will be written with a pencil, not with blood," he insists. In the University of Antioquia, a hot bed of left-wing thinking, Mr Mockus is greeted like a hero. The young make up a huge part of his following and if he wins it will be thanks to their enthusiasm. The students all carry pencils and wear green shirts. In Bogota, a Santos campaign rally had a very different feel to it. It was held in the central landmark Tequendama hotel. Here the crowd wore suits, there were flashing lights and multimedia presentations, all presided over by models who stood around the stage and distributed campaign T-shirts to the faithful. Diego Ospina, who runs a small restaurant nearby, voiced his backing. "Look everyone wants an honest government, but Colombia is at war and we need a war president, a man who can get things done. That man is Santos," he said. Mr Santos comes from unrivalled political stock. His great-uncle was president, his grandfather one of the most prominent political commentators in the country. He has a long and exceptional record in public office. His time as defence minister saw the rescue of 15 hostages from guerrilla hands, among them the former presidential candidate, Ingrid Betancourt. The security situation is always at the back of any Colombian's mind. They do not want to return to the days of a decade earlier when the guerrillas were camped in the outskirts of the cities and kidnappings ran at eight a day. Liberal Party candidate Rafael Pardo has accused the current government and Mr Santos of wanting to make the election about fear. "They want to scare voters into believing that more of the same military approach is needed," he argues. Given the closeness of the opinion polls, it seems Colombians favour both change and continuity. Sunday will show which they are ready to plump for.
Alvaro Uribe casts long shadow over Colombia election

The supermodel posted the magazine's last staff photo, which featured no black faces among the 55-strong team. It was taken before Edward Enninful took the reins as the magazine's first black editor earlier this month. "Looking forward to an inclusive and diverse staff now that @edward_enninful is the editor," Campbell wrote on Instagram. Broadcaster and commentator Edward Adoo said the Vogue staff photo looked like a snapshot of "very old school Britain". He told BBC News: "It seemed there was no room for anyone else. It seemed like the Sloanies' club. In the whole fashion industry, the mainstream element feels very middle class, very white, very controlled, and there needs to be some kind of breakthrough. "I think Edward Enninful is a step in the right direction. He's black, he's gay and he reaches out to different people, and I think that's what's needed." Campbell has the status to speak out, whereas younger models have less power, Adoo said. "For Naomi Campbell to say it, it would certainly silence the critics because of her calibre and status. "But for someone who's up-and-coming to speak out and say, I feel as if I'm not being treated right, or there are no opportunities, they may never ever get a call again." One of Enninful's first appointments was to hire Campbell, Kate Moss and film director Steve McQueen as contributing editors. Speaking to Time last year, he said there needed to be widespread change to make the fashion industry more diverse. "If you put one model in a show or in an ad campaign, that doesn't solve the problem," he said. "We need teachers in universities, we need internships, we need people of different ethnic backgrounds in all parts of the industry. That really is the solution; you have to change it from the inside." In the same interview, Campbell said: "For me, it never stops. It's not a fight, it's a conversation - constantly reminding people that diversity is beautiful and that there should be diversity and equal opportunity. "It never stops because you say it and they say that they listen, and it seems to take two steps backwards." Follow us on Facebook, on Twitter @BBCNewsEnts, or on Instagram at bbcnewsents.
