SPARQL 1.1 Protocol 4.1 Security There are at least two possible sources of denial-of-service attacks against SPARQL protocol services. First, under-constrained queries can result in very large numbers of results, which may require large expenditures of computing resources to process, assemble, or return. Another possible source are queries containing very complex — either because of resource size, the number of resources to be retrieved, or a combination of size and number — RDF Dataset descriptions, which the service may be unable to assemble without significant expenditure of resources, including bandwidth, CPU, or secondary storage. In some cases such expenditures may effectively constitute a denial-of-service attack. A SPARQL protocol service may place restrictions on the resources that it retrieves or on the rate at which external resources are retrieved.
eDonkey network The eDonkey Network (also known as the eDonkey2000 network or eD2k) is a decentralized, mostly server-based, peer-to-peer file sharing network best suited to share big files among users, and to provide long term availability of files. Like most sharing networks, it is decentralized, as there is not any central hub for the network; also, files are not stored on a central server but are exchanged directly between users based on the peer-to-peer principle. Currently, the eD2k network is not supported by any organization (in the past it was supported by the MetaMachine Corporation, its creator, which now is out of business) and development and maintenance is being fully provided by its community and client developers.
Google Dorks cache: If you include other words in the query, Google will highlight those words within the cached document. For instance, [cache:www.google.com web] will show the cached content with the word “web” highlighted. This functionality is also accessible by clicking on the “Cached” link on Google’s main results page. The query [cache:] will show the version of the web page that Google has in its cache. Materiales Didácticos /capacitacion/materiales-didacticos Inicio > Capacitación > Materiales Didácticos Materiales Didácticos Semantic Web Case Studies Case studies include descriptions of systems that have been deployed within an organization, and are now being used within a production environment. Use cases include examples where an organization has built a prototype system, but it is not currently being used by business functions. The list is updated regularly, as new entries are submitted to W3C. There is also an RSS1.0 feed that you can use to keep track of new submissions.
Onswipe Imagine waiting for the train while picking out your groceries from a display case filled with products identical in size, scale and color to really grocery store shelves. If the first round of the digital revolution was about making the real virtual, this time it is about making the virtual real again. South Korean grocery chain Tesco was looking for a way to one-up their major competitor – impossible to do in terms of physical shops due to a lack of actual stores; hence, they turned toward the world wide web with a combination of mobile phone and QR code technologies. Using smartphones, shoppers can browse the isles during time normally spent idle anyway on their way to or from work. Their purchased products are then delivered by the store, waiting for them when they get home and ready to be put right into the kitchen cabinets, refrigerator or freezer.
Topsy - Real-time search for the social web With iOS 9, Search lets you look for content from the web, your contacts, apps, nearby places, and more.

The Semantic Web is a Web of Data — of dates and titles and part numbers and chemical properties and any other data one might conceive of. The collection of Semantic Web technologies (RDF, OWL, SKOS, SPARQL, etc.) provides an environment where application can query that data, draw inferences using vocabularies, etc.
Social Media App Lets You Live Vicariously Through Friends' Experiences Vycarious, a new social-media app that is available for iOS, lets you create, follow and comment on friends' experiences, ranging from a two-week vacation to handcrafting a dinner table. To start, users create an "experience description," such as "cooking Pad Thai." They then choose a photo or video as the lead image, denote a starting date and time, and include hashtags to make their experience searchable. After that, users can upload posts, videos, images and other media until their experience ends. However, friends can still write comments even after users hit the end button to signal that their experience is over. "There just really isn't a way to share an entire experience [on social media]," Rosalie Bartlett, co-founder and CEO of Vycarious, told Mashable. " With Twitter, it's tiny, tiny snippets.
