    I find, in this scenario, Facebook's behaviour immoral. They have known of this problem for three years, and they have yet to produce any progress. Facebook does not seem to respect one's stance on these things. If you wish the picture deleted, then it should be deleted.

    I agree with Morten, if Facebook has known this problem for the past three years they should have done something about it not wait for someone to find out and then apologise and attempt to fix the problem later. However, i'm not quite sure on how this works because I have had friends send me links to pictures that were deleted minutes before and a content error appears and i'm not able to access the picture/link.
  • Mr Brooke on 09 Feb 12
     
    Jorge I think the difference is that if you have a direct link ie the url of the image then you can still see it. A link from someone's wall will be broken and the image will appear to have gone.
  • The Zhan on 10 Feb 12
     
    The apparent deletion of photos takes place by the elimination "all of the metadata for the photo as well as any and all tagging and linking information. For all practical purposes, the photo no longer exists. However, technically, the bits that make up the photo persist somewhere. It's possible that someone who previously had access to a photo and saved the direct URL from the CDN (...) could still access the photo." http://webapps.stackexchange.com/questions/2493/how-long-does-facebook-keep-data-of-a-deleted-account In the article, "Wolens claims that Facebook is on the verge of fixing up its content systems so that "deleted" photos are really, truly deleted from the CDN within 45 days." However, the reliability of this claim is compromised by Facebook's Terms of Service, which every user must comply prior to creating an account. Summing up, it grants Facebook the right to do whatever they like with old content. They can even sublicense it: "You hereby grant Facebook an irrevocable, perpetual, non-exclusive, transferable, fully paid, worldwide license (with the right to sublicense) to (a) use, copy, publish, stream, store, retain, publicly perform or display, transmit, scan, reformat, modify, edit, frame, translate, excerpt, adapt, create derivative works and DISTRIBUTE (through multiple tiers), any User Content." http://consumerist.com/2009/02/facebooks-new-terms-of-service-we-can-do-anything-we-want-with-your-content-forever.html Note the contradictions with the principles of the Data Protection Act 1998: "If you collect data about people for one reason, you can not use it for another; You can not give people's data to other people or

    ...organizations unless they agree;" http://simple.wikipedia.org/wiki/Data_Protection_Act I get the impression that through blurring the ownership of intellectual property and personal records, social networks have some ulterior motives. The following passage in the article suggests the photos could, in fact, be instantly deleted from the CDN databases: "(Amusingly, after publishing the 2010 followup, Facebook appeared to delete my photos from its CDN that I had linked in the piece. (...) Other "deleted" photos that I had saved links to-ones that weren't from my account and were deleted even earlier than mine-remained online.)" Zuckerberg counterargues: "trust us, we're not doing this to profit from you, it's so we are legally protected as we enable you to share content with other users and services." http://consumerist.com/2009/02/facebooks-new-terms-of-service-we-can-do-anything-we-want-with-your-content-forever.html In the end, it is in the hands of the user to control what is shared and given up ownership of.

  • Unable to keep up with the 21st-century transition from film to digital technology, Kodak listed a debt of $6.8 billion
  • Kodak has been felled by exactly what it espoused: universal access to cameras.
  • Isy :) on 21 Jan 12
     
    The main social and ethical issue that this article brings up is that of people and machines. The fact that Kodak has declared bankruptcy is hardly surprising, as though they were the company who worked so hard to develop the world of photography, they have failed to develop themselves in order to adapt to the new world of photography, while other companies such as nikon, samsung etc, have by constantly creating new digital cameras with new attractive features. This article is recent story of how Kodak are trying to sue Samsung for potentially infringing one of their patents: http://www.bbc.co.uk/news/technology-16631710 This article is prime example of how having an innovative idea is simply not enough to be successful over an elongated period of time: Just because Kodak had the idea of digital photography, that does not mean that they did not have to compete with other companies to remain the leading brand in photography. It seems to me that Kodak's complacency after having had the idea of digital photography led to their downfall. Explain the relationship between the IT system (digital photography) and the social/ethical (people and machines) The article shows how for the the public to continue to have an interest in machines such as digital cameras, they must continue to be developed, improved, updated and upgraded, as the appeal of new technology attracts customers. In this case, Kodak failed to keep up with the rate at which the world of digital photography is evolving.

    anyone want to try and describe step by step how this system works?
  • Jorge F1 on 18 Jan 12
     
    Basically the car works with a Velodyne 64-beam laser mounted on the roof on the car, the laser produces a detailed 3D map of the environment and takes measurements of the area. The car uses the data from the 3D map and the measurements to avoid obstacles and respect traffic laws. Furthermore, the car uses various sensors, two of which are placed on the front and rear bumpers to track obstacles. There is also a camera, that detects traffic lights, GPS, inertial measurement unit, and wheel encoder, that determine the vehicle's location and keep track of its movements. In my opinion, the idea of a self driving car is incredible if it is built correctly, however I believe that the wheel encoder may invade the privacy of some.
  • Morten Nielsen on 18 Jan 12

    Because the car records it's position using the GPS, if a black hacker is able to get hold of this information the owner of the car could be put at risk.

    In my opinion, the main objective is purely to protect the entertainment industry by blocking infringing domain names however, as stated in the video these industries do not contribute so much to the US economy. Furthermore, theses bills will put the stability of new search engines at risk as the US government will be able to sue them if they advertise any infringing website.

  • Fiche Galinha on 19 Jan 12
     
    Although protecting the entertainment industry from piracy and blocking certain websites containing disturbing and innappropriate material (paedophilia) is a good idea, the way SOPA and PIPA have been written/proposed makes it very easy for people enforcing both acts to abuse their power. Once we censor one thing, other will decide that other things must also be censored, therefore destroying any sembelence of free-speech Internet users have. I also find it worrying how the American Senate decided by itself that these two acts should be made law, in the process crippling the Internet, a resource used by billions of people all around the world and not just the population of the US.

    Criterion B . Describe, step by step, how the IT system works. How unauthorised sites outside usa jurisdiction is censored within american borders: A little bit like the great firewall of China, this kind of censorship takes place at a router level. 1. The American ISPs enter the domain names of the unauthorised sites and directories, blogs and forums that contain related links into the Internet routers. These enable data to flow back and forth between ISPs in the USA and Internet servers around the world. 2. The user types in the domain name of an unauthorised website. 3. The request is sent to the web server at the ISP, and the domain name is looked up on the database of addresses in the router 4. The router denies the request from the web server 5. An error message appears in the user's browser how chinese censorship works - http://embargo.gn.apc.org/3.htm#_ftn5 how internet works - http://www.explainthatstuff.com/internet.html

    The SOPA is mainly adresses the protection of intellectual property of content creators. Obviously this is the one of the biggest advantages being proposed by the act as artists and entertainers will be able to profit more from the content they make. Nowadays much of their content is illegally downloaded from the internet, such as music. However SOPA will have a severe impact on online freedom of speech as numerous websites would be affected by the act and blacklisted as a result. The internet is makes frequent use of copyrighted material not necessarily in a legal way. Doing streaming of such content after the act could lead to a maximum penalty of five years in prison. However the US congress states that protecting intellectual property is not the same as censorship http://agbeat.wpengine.netdna-cdn.com/wp-content/uploads/2011/12/sopa-infographic1.png The image above provides more detail about SOPA including how it will take effect and the impact it would have on businesses. It shows the major supporters of SOPA as well as the major opposers, one of them being Google.

DNA link led to sex attack arrest - 4 views

    The national DNA database proved "uniquely crucial" in an investigation that led to the conviction of a sex attacker in Essex. But police fear the service that helped to link Lawrence Button to the sexual assault of a former University of Essex student, in 2009, may be scaled back.
  • ...3 more comments...
  • The Zhan on 06 Jan 12
     
    This article compromises the privacy of British citizens, as well as the reliability and integrity of the DNA database. I will focus my comment on the latter. It was a matter of fortune that Button's DNA had been collected due to his arrest for a domestic assault in May 2010. This is because according to the Protection of Freedoms Bill, biometric material can only be retained if the holder consents it formally. This consent "can be withdrawn at any time". There are also strict regulations on the amount of time that a DNA profile can be retained by authorities according to the new Bill. In addition to that, what way is there to ensure the 62 million(http://en.wikipedia.org/wiki/United_Kingdom) British citizens have their DNA profile taken and input in the database? This compromises the integrity and completeness of the DNA database. According to the article itself, "The national database is believed to hold over five million DNA profiles". The new Bill also "requires schools to get parents' consent before processing children's biometric information" (http://services.parliament.uk/bills/2010-11/protectionoffreedoms.html) The full official bill on the regulation of biometric data can be found at: http://www.publications.parliament.uk/pa/bills/lbill/2010-2012/0099/lbill_2010-20120099_en_2.htm#pt1-ch1-pb1-l1g1 Hence the sweeping statement "The odds, we were told, were over a billion to one, so we were quite confident we'd got the right man", is certainly misleading, because the database is likely not to include a fraction of the British population. The most disturbing thing is that the responsible chief Richard McNamara states "it was the DNA alone that convicted the man, because we never had any other evidence". Is it really ethical to convict a criminal solely based on a potentially incomplete database? A solution to this problem would be to enforce surveillance systems and active police monitoring in order to obtain more plausible evidence.

  • Mr Brooke on 06 Jan 12
     
    "The Zhan" you raise some interesting points on the privacy issues of DNA databases. However I think you may have misunderstood the reliability issue of the DNA test. When two DNA samples are found to be the same then it is 99.99% certain that it is in fact the DNA of the suspect and is a very reliable indicator that it was that person. There are forensic issues involved in the collection and contamination of DNA samples from a crime scene but that is another issue. The main social and ethical issue here that you have rightly pointed out is the collection and storage of DNA from people. This article outlines some of these issues from 2008: http://news.bbc.co.uk/2/hi/uk_news/7177152.stm Here the issue of innocent peoples data being stored has come because ....."following a change in the law in 2001, all DNA collected by forensics - for whatever purpose - can be stored permanently. " It was promised in the recent election in the UK to destroy old data but it appears to be one of the many U turns that the current government has made: http://www.telegraph.co.uk/comment/telegraph-view/8659968/A-Bill-to-curtail-our-liberty.html
  • The Zhan on 06 Jan 12
     
    I agree with your first point to some extent, but I think that implying that it DNA profiling is 99.99% accurate is when in fact it is 99.9999999999% accurate (one to a trillion sir, get it right), is not acceptable - according to this http://www.guardian.co.uk/commentisfree/henryporter/2009/may/25/dna-database-false-positive I think that retaining DNA samples in databases and profiling an individual in a pervasively detailed manner could lead to extremes such as that of convicting criminals for pre-crimes, as portrayed in the film Minority Report. That would heavily compromise a citizen's privacy. http://3.bp.blogspot.com/-I7tBjrA8Mj0/TWPfWNY9-0I/AAAAAAAAADg/QTXlFpTtNvM/s1600/MINORITY+REPORT.jpg "The US government has come up with a Big Brother-esque machine that senses if an individual intends to do harm".

  • A few years ago, Nass worked on a study about how multitasking affects adults. He found that heavy multitaskers experience cognitive issues, such as difficulty focusing and remembering things. They were actually worse at juggling various activities, a skill crucial to many people's work lives, than those who spent less time multitasking, Nass said.

    (CNN) -- FaceTime, the Apple video-chat application, is not a replacement for real human interaction, especially for children, according to a new study.

    Employees of Silicon Valley giants like Google, Apple, Yahoo and Hewlett-Packard opt to send their children to computer-free Waldorf schools. These subscribe to a teaching philosophy focused on physical activity and learning through creative, hands-on tasks. They affirm that computers inhibit creative thinking, movement, human interaction and attention spans. Computers are not allowed in classrooms and "their use at home" is frowned upon. "Teaching is a human experience," says an associate professor of education at Furman University, "Technology is a distraction when we need literacy, numeracy and critical thinking." "And where advocates for stocking classrooms with technology say children need computer time to compete in the modern world, Waldorf parents counter: what's the rush, given how easy it is to pick up those skills?" http://www.nytimes.com/2011/10/23/technology/at-waldorf-school-in-silicon-valley-technology-can-wait.html?_r=4&pagewanted=all

    It's true that computers can give a person bad habits, I do not doubt that. But the article is not offering any numbers nor web page reference of any kind; so we cannot verify this easily. However, my point is that perhaps computers have not made anyone more antisocial, than what they would have been without computers. The articles says that "Young girls who spend the most time multitasking between various digital devices, communicating online or watching video are the least likely to develop normal social tendencies", but what is "normal social tendencies"? There will be some of these young girls without "normal social tendencies", but I doubt that the difference between these young girls, and the ones who does not multitask - is about the same amount of girls without these normal tendencies. Not all mice are gray, some are brown. Not all users of IT are antisocial, some who aren't will be antisocial as well.
