“The researchers’ free software, called Tribler, uses a modified version of the popular BitTorrent file-trading algorithm. This requires people downloading a large file from a single source to pass segments of it on to other downloaders, dividing up bandwidth usage and speeding downloads. Unlike BitTorrent, however, Tribler asks users to “pay” for the bandwidth they consume by offering up more of their own in return. This is designed to tackle a common problem with peer-to-peer networks known as “leeching” or “free-riding”, where users download lots of data but refuse to upload it, in order to minimise their personal bandwidth usage. Use of Tribler is governed by a market in bandwidth, analogous to a market for physical commodities like oil. Users earn credit by uploading and can then spend it by downloading.”

“Ci stiamo forse avvicinando all’inizio della quarta era di quella che una volta chiamavamo “Information & Communication Technology”? Abbiamo visto la prima, l’informatica centralizzata, dominata da IBM. La seconda, il desktop computing, da Microsoft. La terza, quella attuale di Internet, da Google. La prossima sarà quella del vero e proprio mobile computing.”

—Are You Paying Attention?: Facebook is using your data to target ads at you
“The truth is, however, that unless Facebook begins to adopt more standards and open up its platform for export, it will be usurped by the first medium-scale network to do so.”

“A key point is that The Attention Economy is about the consumer having choice - they get to choose where their attention is ‘spent’. Another key ingredient in the attention game is relevancy. As long as the consumer sees relevant content, he/she is going to stick around - and that creates more opportunities to sell.”

“Forse che c’è un limite a cui il web si approssima, che definisce ciò che possiamo ragionevolmente attenderci da questo medium. E questo limite è il senso che donne e uomini in carne ed ossa conferiscono all’informazione. Forse dovremo renderci conto di questo limite e mettere meglio a fuoco i suoi contorni. Conoscendo il limite, forse un giorno potremo raggiungerlo.”

“I don’t really like the term “collaborative intelligence”—it sounds too buzzy—so we tend to call it “collaborative co-creation” instead.”
—Augmented Social Cognition: Wisdom of the Crowd, Collective Intelligence, and Collaborative Co-creation
“This feedback cycle is the part we’re really interested in understanding, because coordination is at the heart of collaborative creation. We want to understand how people are coordinating with one another through either self-organizing mechanisms or through explicit organizing mechanisms; we want to understand the principles by which those things happen in these environments but not in other environments.”

“l’effetto San Matteo presuppone che i motori di ricerca influenzino il traffico degli utenti attraverso rigide strategie di posizionamento delle pagine, e si è argomentato che possano generare una spirale tutt’altro che virtuosa che amplifica la dominanza dei siti già popolari secondo una strategia legata al ranking. Questa polarizzazione potrebbe cioé condurre ad un monopolio pericoloso delle informazioni: una rete non democratica.”

“L’effetto San Matteo viene, in altre parole, mitigato dal funzionamento dei motori e soprattutto dal comportamento degli utenti.”

“Il risultato ha conseguenze concettuali e pratiche interessanti: suggerisce, controintuitivamente, come l’uso “sociale” dei motori di ricerca contribuisca a “livellare” la popolarità delle pagine, cosicché anche i siti meno popolari hanno una probabilità, superiore a quanto ci si attenderebbe, di essere trovati, e questo grazie alle dinamiche della psicologia sociale applicate alle reti di informazione.”

“Red Shift Redefined
• Red shift refers to companies experiencing exponential growth in demand for raw computing power
• Red-shift companies tend to be Web 2.0-focused like YouTube and MySpace, or big financial, energy, and pharmaceutical companies
• Those companies, Sun CTO Greg Papadopoulos says, will experience similarly high levels of growth in users, revenue, etc., while blue-shift companies will grow relative to GDP
• Along with the cost of powering and cooling in-house data centers, the red shift is driving a surge in utility computing and software as a serviceDatabase calls have gone from millions to billions, says Salesforce’s Fisher Red-shifting companies will experience explosive growth, predicts Sun’s Papadopoulos” —The Red Shift Theory - Hardware - www.itnews.com.au
