BOINC: A System for Public-Resource Computing and Storage - 0 views

  •  
    This resource is written by David P. Anderson from the University of California, Berkeley, the original founder of the SETI @home Project (Gomes, 2006) and discusses public-resource computing in more detail. It talks about the benefits of it over grid-computing and goes into more detail about the BOINC (Berkeley Open Infrastructure for Network Computing) Platform for public-resource computing. Public-resource computing (also known as "global computing", "distributed computing" or "peer-to-peer computing") uses available resources on personal computers to do "scientific supercomputing" (Anderson, 2004). It also has the benefit of "encouraging public awareness of current scientific research". SETI @home, one of the most well known forms of public-resource computing, attracts millions of users worldwide and can provide 70 TeraFLOPS of sustained processing, versus approximately 35 TeraFLOPS from the largest conventional supercomputer (Anderson, 2004). The goals of BOINC include: * Reduce the barriers of entry to public-resource computing. * Share resources among autonomous projects * Support diverse applications * Reward participants There are now a number of projects that use BOINC other then SETI@home. These include: * Predictor@home - studies protein behaviour * Folding @home - studies protein folding, misfolding, aggregation, and related diseases. * Climateprediction.net - quantifies and reduces uncertainties in long-term climate prediction based on computer simulations. * Einstein@home - detects certain types of gravitational waves, such as those from spinning neutron stars, that can be detected only by using highly selective filtering techniques that require extreme computing power.

    By participating in these projects members can feel like they are playing a small part in helping with curing disease, solving global warming, and other world issues. Attracting participants is always a goal of these projects so it's important that these computing programs give no real inconvenience to them. BOINC has a general preference option that allows members to set a number of features including how and when their computer resources are used. This includes "whether BOINC can do work while mouse/keyboard input is active", hours of use, how much disk space can be used, and the network bandwidth. BOINC allows for many different projects to use its systems/setup allowing for smaller research projects to take advantage of the greater computing capabilities. This could potentially in the future help out an unknown research make a global scientific discovery. Anderson, D. (2004). BOINC: A System for Public-Resource Computing and Storage.

Website helps to make dreams come true - 0 views

    ABC LATELINE Michael Atkin Byline: "Australian website Pozible is helping to connect generous donors with needy projects, but there are concerns about how the website operates." The article introduces crowd-funding as an 'innovation of the internet age', bringing together donors and projects in need of funding, using an environmental group called Green Way Up as an example project, and a website called Pozible as an example of a crowd-funding resource. As an introduction to crowd-funding it presents Green Way Up as being both environmentally and socially conscious, as well as a good example of a crowd-funded project worth attention: Bob Miles and Chuck Anderson want to travel around the world on bio-fuel converted from recycled fats and oils obtained, in one case, from the waste of a chicken shop. However, Green Way Up may not have had such a start toward achieving this venture if not for Pozible; a crowd-funding resource whose Co-founder, Rich Chen, created the site 'because he was sick of hearing about exciting projects which failed to go ahead because they lacked money' (Atkin, 2011). Though it presents a hopeful opportunity to projects and financial benefactors alike, the article turns critical of the website's operations, suggesting Pozible may be 'violating the Corporations Act by raising money and offering rewards without issuing a prospectus' (Atkin, 2011).
  •  
    Jennifer McKay, Professor at the University of South Australia is also concerned that Pozible infringes upon consumer protection laws and security laws, but when asked by Lateline, the Australian Securities and Investment Commission said they were 'considering whether crowd-funding poses any regulatory concerns' (Atkin, 2011). Green Way Up is presented as an exception rather than a rule for projects seeking crowd-sourced funding; '[p]rojects only receive the money if they reach their funding target within 90 days and currently two-thirds fail' (Atkin, 2011). Built upon and relying heavily on trust, the article concludes there is potential risk for all involved. Atkin, M. (2011). Website helps to make dreams come true. Lateline.

    SETI@home and the various other projects that use BOINC rely on public contributions to achieve their computer processing goals. In a similar vein, the website Pozible.com.au also relies on public response to assist what would otherwise be unheard of projects. Pozible is a website that uses "crowd-funding" to get its donations. "Crowd-funding is an innovation of the internet age which links generous donors with needy projects" (ABC, 2011). In the example provided by this resource, the needy case is an environmental group called Green Way Up who want to fund an expedition to Norway using only bio-fuel. First shown on ABC's Lateline on the 1st April 2011, this interview discusses numerous aspects of Pozible. It talks through the set-up process, talks to a donator, and even questions the administration process from an ASIC/ACCC point of view. Not only does this website help otherwise unknown projects get up off the ground, it also helps connect them to "lounge-chair activists" looking to donate to causes they believe in. There are still a few problems with the donation process. Projects are required to generate 100% of their goal amount within 90 days to receive the money, meaning that currently only 1/3 of projects achieve this goal. There is also no formal follow-up process to ensure that the projects do what they have promised. On a positive note however, if a project fails to meet the requested total, no money changes hands. Donations work more on a pledge system, and even Pozible makes no profit from the projects, unless this total is met(Pozible.com, 2010). Projects like BOINC and Pozible are innovative ways of using current computer/internet usage to get public interest and participation in what could otherwise be undiscovered projects that could have positive implications in the future.

Twitter as Medium and Message - 0 views

    Savage, N. (2011). Twitter as Medium and Message. Communication of the ACM, 54(3), 18-20. Researchers say the Twitter data may help answer sociological questions that are otherwise difficult to approach. Their research documents the Twitter in means of social media that gives people opportunities for tracking what people are saying about everything. The Twitter opens access to tweets with range of incredible number of topics and subjects that people tweet about. For example a scientist at the Louisiana University used the Twitter for a simple search using a few influenza related keywords. This simple search enabled him to predict future influenza outbreaks. The Twitter's data assisted in another professional field called Air Twitter project at the Washington University in St Louis. The Twitter was engaged for additional provision of information or tweets about events like dust storms, fires, air quality and similar. A similar approach was explored by US Geological Survey (USGS). The Twitter was used for messages in means of a supplement to USGS network of seismographic monitors that alert the federal agencies about occurring earthquakes. Another good example is from psychology field where the Twitter was used for the sentiment analysis of tweets. Researchers used 'Affective Norms for English' tool used in psychology that rates the emotional value of words. The analysed tweets revealed data about particular group happiness levels. The real examples above reveal how data from the Twitter can assist in gaining valuable information either for the medicine, natural disasters or just about happiness levels. The Twitter has been recognised as extremely useful tool for gathering data that would be otherwise difficult to search. Twitter's fast and cost free access to information is very useful for the sociological purpose. Of course, there is always potential for spread of unfiltered information that can invite a possibility of abuse, incorrectness and other negati

    Paula, an excellent and timely article which shows how Twitter has become a collaborative tool for research and data collection purposes. A leading researcher in this area is academic Dr Steve Wheeler at the University of Plymouth in the UK. He quotes a teacher on Steve's blog who states that he uses Twitter 'is because his community - those he wishes to connect with - are best contacted using it' (Wheeler, 2011a). Indeed Steve argues that connections of both research information and data can be found simply by following academics in your field on Twitter. Although such communications can often be one-way but as your article states, the potential for both medium and message, i.e. this can be interpreted as data and research, as leads to what you want can be invaluable if protocols are followed (Wheeler, 2011b; Savage, 2011). For example, people do collaborate simple nights out with friends on Twitter, so therefore why is collaborating on a large project by using contacts on a professional an ideal? Sometimes it depends on Twitter's image as a social media nattering device (Wheeler, 2011b). I agree that Twitter has had an image problem to overcome. But your article does prove it is being used for research advancement. The dust storm data for example shows what is possible to collect and how getting data transcends time and physical borders. However, it is vital that etiquette be followed, perhaps even making Twitter networks private, and the information is check for credibility. These are the challenges Twitter users face; yet to have this collaboration tool is vital for broadening access to research data and findings. References Savage, N. Twitter as Medium and Message.

    As BOINC is being used to further research projects through public-resource computing, so too is Twitter, another form of online collaboration, now being used for research. "Researchers are finding they can measure public sentiment, follow political activity, even spot earthquakes and flu outbreaks, just by running the chatter through algorithms that search for particular words and pinpoint message origins" (Savage, 2011). Due to the real time nature of "tweets", researchers can get early warning signs of events like earthquakes by searching twitter for key words like "OMG earthquake" and other related words. Programs can also be written to exclude unrelated words, for instance when looking for flu outbreaks, comments like "Beiber Fever" can be instantly excluded. Although at this stage this form of research can not be 100% accurate it can give a picture of what is happening. Twitter can also give researchers a more subjective point of view. It can look at how the people are affected by an earthquake, instead of just giving statistics on building damage and repair costs. As with anything there can be some problems related to using twitter this way. The first is "sample bias". Information gained in this way relies on the users having a computer, internet access and a twitter account. Although in the western world percentages of this would be high, in poorer nations this usage would drop significantly. However this problem can be addressed. Researchers wanting "to glean insights from tweets can apply corrections to the sample, just as traditional pollsters do" (Savage, 2011). The other problem is that of spam, or users hoping to improve the chance of their tweet gaining high rating by re-tweeting on the same topic. For example in an American election a conservative group sent out "929 tweets in just over two hours" (Savage, 2011) with a link that attacked a representative. This can then affect the data bias.

Avaaz - The World in Action - 3 views

  •  
    "Avaaz is a global web movement to bring people-powered politics to decision-making everywhere" (Avaaz.org, 2011). Avaaz means voice, in "... several European, Middle Eastern and Asian languages" (Avaaz.org, 2011a). This is not a website where you need to prove your credentials or log in to be a member. However, it is one of the most powerful and influential organisations in the world. The Avaaz community "... empowers millions of people from all walks of life to take action on pressing global, regional and national issues, from corruption and poverty to conflict and climate change" (Avaaz.org, 2011a). Their online platform "... allows thousands of individual efforts, however small, to be rapidly combined into a powerful collective force" (Avaaz.org, 2011a). The Avaaz community supports campaigns in 14 languages, has a core team on 4 continents, includes thousands of volunteers. Overall, the community helps organise the signing of petitions, funding media campaigns and direct actions, contact through emailing, calling and lobbying governments, and organizing "offline" protests and events. They do this to "... ensure that the views and values of the world's people inform the decisions that affect us all" (Avaaz, 2011a). Two very good examples of the strength of the community include: * Stand With Anna Hazare (Avaaz.org, 2011b) shows of a petition where over 624,876 people have signed since the campaign launched on the 7th April, 2011. Before the goal of one million signatures was reached, a victory has been announced. * Blackout-proof the protests (Avaaz.org, 2011c) is a current petition to "...secure satellite modems and phones, tiny video cameras, and portable radio transmitters, plus expert support teams on the ground -- to enable

    The opening statement to this web site reads " Avaaz is a global movement to bring people-powered politics to decision-making everywhere" (Avaaz.org, 2011) Immediately the reader is in no doubt that this is an organisation that is able to bring together large numbers of people to influence governments worldwide. Like other commentators I had not been aware of this organisation and spent some time researching. Unlike flash mobs and Anonymous, it appears that Avaaz has a formal structure and employs staff. As their website points out the staff write email alerts to the community and work with experts to develop campaign strategies (Avaaz.org, 2011). But it is the Avaaz community that decide where and how to campaign. This is very reminiscent of the Australian Democrats, where all policies are decided by a poll of members (Australian Democrats, 2011). Flash mobs occur in local communities, but the global nature of Avaaz means that this can be magnified to call attention to new issues on a worldwide or country-by-country basis if needed. The key to Avaaz, flash mobs and Anonymous is the use of Internet communication Technology. As the Avaaz website points out in "previous times each group would need to build up a constituency to reach a scale that could make a difference….Today thanks to new technology and ….. global interdependence this constraint no longer applies" (Avaaz.org, 2011).

    Avaaz's systems of collaboration allow decentralized networks to form around community and global projects, " ...(taking) action on pressing global, regional and national issues, from corruption and poverty to conflict and climate change" (Avaaz 2011). The Avaaz community, like Anonymous, are examples of how decentralized networks of like-minded individuals are capable of achieving common goals. The influences and successes that these groups are currently having regarding the sharing of global resources and fighting for basic human rights and freedoms of information show how powerful these network structures can be. The strength and flexibility of collective intelligence networks such as Avaaz and Anonymous is found in the diversity of their participants. For example, Avaaz uses methods that "allows thousands of individual efforts, however small, to be rapidly combined into a powerful collective force" (Avaaz 2011). Similarly, Anonymous is "a loose network of people with shared values and varying skill sets" (Anonymous, 2011). Like all collective intelligence networks, every member of these groups is acknowledged as having valuable skills that can benefit the community - so a method of harnessing this is input has been developed. However Avaaz and Anonymous use different techniques regarding how they attempt to achieve their goals. Avaaz use socially and politically transparent methods of traditional protest such as "signing petitions, funding media campaigns and direct actions, emailing, calling and lobbying governments, and organizing "offline" protests and events". In contrast, Anonymous are notorious for their use of "distributed denial of service (DDoS) attacks" using software such as 'Low Orbit Ion Cannon'; or 'LOIC' (see, Arthur, C. 2010). These different ways of collaborating online show that while "the social, political and technological environment has developed, some have already begun to explore new options, seizing new chances

    Avaaz addresses global issues to generate global interest in improved conditions - globally. The world in action (Avaaz.org). Available in fourteen different language, it encourages borderless interest in issues relevant locally and internationally, promoting campaigns to 'close the gap between the world we have and the world most people everywhere want' (About Avaaz, n.d.). Avaaz is to the world what GetUp! is doing for Australia, including its policy on transparency, evidenced in the availability of financial reports, member statistics, and its member-funded, crowd-sourced model. Rather than a distributed, region-dependent staff and budget, Avaaz has a 'single, global team with a mandate to work on any issue of public concern' (Avaaz.org, n.d.). It is Avaaz members who decide where to direct resources The website projects a sense of global community, as much in being available in so many languages as in movements presented on every page heralding from many different countries representing the plights of many and varied communities. Avaaz is a global example of social awareness instigating social movements, easily promoted through the connectivity of the internet and the tools for social networking, to create a better world. Websites and movements for campaigns such as Avaaz and GetUp! Australia are helping to raise awareness and reclaim power for the people. Avaaz.org.(2011). The World in Action.

    As yet another online resource for the "lounge chair activist" Avaaz.org seems to cover it all. Whether you're interested in saving the whales, climate change, gay rights or donating to flood victims, there is a cause available for you. Avaaz, started in 2007 with the mission to "organise citizens of all nations to close the gap between the world we have and the world most people everywhere want" (Avaaz.org, 2011). So far they seem to be achieving this goal. With over 8 million members worldwide, who have so far taken over 38 "actions" this is a website that seems to be doing what it's promised. To ensure that there is no underlying bias, no political voice hiding behind the curtains, Avaaz ensures there is "democratic accountability" by being 100% member-funded. It is mainly staffed by volunteers, who email actions to members in way that registers interest in the project and nothing more. These actions are also normally put forward by Avaaz members themselves, rather than outside parties. Avaaz, like BOINC, relies on word-of-mouth to spread the word. Also using social network sites to keep up the interest between members. Their hope is that once someone joins through a campaign for one specific issue, that they will then continue to support other actions. To prove their success, after "China's violent crackdown on the March '08' protests and riots in Tibet"(Avaaz, 2011) Avaaz was able to build the most successful global position to date. They were able to achieve 1.5 million signatures in just three weeks calling for dialogue between China and the Dalai Lama. Whether you just sign a petition or donate money, having so many available voices ensures that Avaaz will make it count. As stated by Zainab Bangura, the foreign minister of Sierra Leone "Avaaz is an ally, and a rallying place, for disadvantaged people everywhere to help create real change"(Avaaz, 2011). Avaaz.org.

How Many Computers Does It Take to Make Contact with E.T.s? - 1 views

  •  
    This resource, an article from the Wall Street Journal, is a more current take on the SETI @home project. It can be more easily understood by the average reader and gives a summary of both the history of the SETI @home project, and information on where it stands today. It also discusses further details of "distributed computing". According to this resource, late in the 1990s University of California, Berkeley scientist David P. Anderson thought that the millions of "often-idle computers"(Gomes, 2006) could be better utilised in distributed computing. The idea behind distributed computing is to take a scientific problem, and then share out the computations required to millions of computers. To test this theory, Dr. Anderson chose the SETI project, and set up SETI@home. Although the search for Extraterrestrial Intelligence was basically an "attention-getting gimic" (Gomes, 2006), it worked better then expected with almost a million users signing up and downloading the required client. Although there are now many other distributed computing projects available, almost akin to choosing which charity to donate to, many users are still loyal to the original SETI @home project. With their accumulated point system, earned by the number of computing hours donated to the project, users are unwilling to move to another project and lose the points they have earned. The current popularity of this project is shown by the 10,000+ members of the SETI @home facebook page (Facebook, 2011), which also demonstrates how many forms of online collaboration often cross paths. This resource describes the SETI @home project in easy to understand language making it a good introduction to the theory of distributed computing (or public-resource sharing) however some of the information seems to contradict that written on the SETI @home about page.

    SETI@home has also inspired other collaborative shared computing projects. Most notably the Folding@home project conducted by Stanford University (Sony folding@Home 2008). The aim is to analyze proteins in hope of solving various diseases including Cancer. An interesting aspect of the project is its imbedding as a networked technology in the millions of PlayStations 3's around the world. As a user-setting, PlayStations left idle can shift processing resources to working through the protein work packets sent out by Stanford. Like the SETI Project, various teams compete for most work units analyzed. As an addition, Stanford are in the process of publishing peer reviewed results that stem from the completed work (Stanford 2009). Both this and the SETI Project hold technology as the central core of collaboration, but there is a human social factor playing an important role. Highlighted by the the team-play that gathers around the competition to see who is putting the most resources into completing work units. Sony folding@home (2008).
