  • The internet has quietly infiltrated our lives, and yet we seem to be remarkably unreflective about it.
  • All of which might lead a detached observer to ask: if the internet is such a disaster, how come 27% of the world's population (or about 1.8 billion people) use it happily every day, while billions more are desperate to get access to it?
  • THE WEB ISN'T THE NET
  • ...8 more annotations...
  • So the thing to remember is this: the web is huge and very important, but it's just one of the many things that run on the internet. The net is much bigger and far more important than anything that travels on it.
  • On the internet, web pages are only one of the many kinds of traffic that run on its virtual tracks.
  • 5 COMPLEXITY IS THE NEW REALITY
  • 6 THE NETWORK IS NOW THE COMPUTER
  • 7 THE WEB IS CHANGING
  • But in fact, the web has gone through at least three phases of evolution – from the original web 1.0, to the web 2.0 of "small pieces, loosely joined" (social networking, mashups, webmail, and so on) and is now heading towards some kind of web 3.0 – a global platform based on Tim Berners-Lee's idea
  • For baby-boomers, a computer was a standalone PC running Microsoft software.
  • First, the companies (Yahoo, Google, Microsoft) who provided search also began to offer "webmail" – email provided via programs that ran not on your PC but on servers in the internet "cloud".

  • But during internet veteran Tim O'Reilly's keynote speech at the Web 2.0 Expo in San Francisco, he looked back over the past five years to demonstrate that the "baby we built with technology is growing up and it's starting to go to work".
  • he web was more than just a fun place to hang out and catch up with friends on Facebook or MySpace.
  • There are still a lot of challenges around that we haven't solved
  • ...11 more annotations...
  • "We are starting to see a co-ordination of these sensors. That is the future,"
  • He then told the audience that this led to a formulation "moving beyond Web 2.0 as it really engages with the world, it really becomes something profoundly different and we are calling it Web squared".
  • At that point, a slide came up with the words "Web 2.0 + World = Web Squared."
  • "Web 2.0, as a set of ideas, is alive and well," he said.
  • Mr O'Reilly described how they were increasingly interacting with the world through the use of sensors.
  • But Web 2.0 has a healthy future
  • I don't really care what it's called. I care that people understand that delving into this concept and building businesses and applications and products out of it is a way we can innovate in our economy.
  • Twitter is a classic example of the 'power of less'
  • Mr Elliott
  • was disappointed that he was not seeing more cutting edge innovation at this year's Expo
  • it's important to keep innovating and to keep finding those big ideas

  • Predavanja zvenečih svetovnih znanstvenikov le 'klik' stran Intervju z urednikom portala Davorjem Orličem 24. februar 2013 ob 07:00 Ljubljana - MMC RTV SLO "VideoLectures.Net so v resnici mala univerza, ki je vsem dostopna in na kateri lahko vsak kaj najde," Davor Orlič pojasnjuje idejo za inovativnim, uspešnim in nagrajenim projektom IJS-ja.
  • Spletni portal, nekakšen znanstveni YouTube, ki ga ustvarja manjša ekipa sodelavcev na Inštitutu Jožef Stefan, poznajo vsi, ki se navdušujejo nad dodatnim znanjem, izobraževanjem in informacijami z najrazličnejših znanstvenih področij. Njegov izjemen prispevek k omogočanju kroženja znanja so prepoznali tudi v Združenih narodih in Unescu, saj so jih pred dnevi razglasili za najboljši produkt desetletja v kategoriji "e-znanost in tehnologija". Na portalu so namreč vsakomur dostopni videoposnetki predavanj odmevnih znanstvenikov, raziskovalcev in direktorjev, kar pomeni, da lahko kar v svoji sobi prisluhnemo, kaj je v zadnjem predavanju povedal Noam Chomsky ali Tim Berners-Lee, ki je zasnoval svetovni splet. Tako lahko vsak, ki ima dostop do spleta, prisluhne znanju s Harvarda, Oxforda, MIT-ja, pa tudi z ljubljanske univerze.
  • O projektu in njihovem poslanstvu smo se pogovarjali z urednikom portala Videolectures.net Davorjem Orličem.

  • Menim, da smo na začetku bili ena prvih spletnih videoknjižnic
  • Večinoma nas povabijo, da pridemo snemat, kar pomeni, da razumejo, v kakšne promocijske namene jim služi posneti dogodek. Tudi mi, predvsem v bližnji okolici, stopimo v stik z organizatorji, če zasledimo predavanja eminentnih avtorjev. Nazadnje smo tako dali pobudo za snemanje predavanja Noama Chomskega v Trstu.
  • Pozitivni odzivi pa niso le v znanstveni ali razvojno-raziskovalni skupnosti, temveč predvsem pri gledalcih videoposnetkov. Teh mi ne imenujemo uporabniki, temveč učenci (learners).
  • Za nas je pomembno, da so to brezplačna, odprta predavanja in da je avtorjem to všeč - da dajo svoje stvaritve na razpolago vsem in razumejo, da gre za širjenje znanja.
  • gre za popularizacijo, a ne v smislu, da bi se snov predstavljala na enostaven način. VideoLectures.Net so v resnici mala univerza, ki je vsem dostopna in na kateri vsak lahko kaj najde, če ima čas, da si ogleda 45-minutne posnetke, in željo po učenju.
  • Lahko naštejete nekaj imen znanih predavateljev, ki so objavljeni pri vas?Slavoj Žižek, Jure Leskovec, Umberto Eco, Noam Chomsky, Walter Lewin iz MIT-ja, Tim Berners-Lee – izumitelj interneta. Presenetljivo veliko znanih imen je pri nas.
  • Veliko pa je tudi slovenskih predavanj, okoli 1.700. To je največja takšna slovenska nacionalna zbirka. Trenutno imamo nov projekt, s katerim raziskujemo možnost avtomatičnega podnaslavljanja in prevajanja podnapisov za predavanja, da bi omogočili vsem gledalcem predavanja v njihovem jeziku.
  • Na portalu je trenutno 16.000 predavanj, ki so večinoma v angleščini.
  • Ogledov imamo okoli 10.000 na dan. YouTube ima seveda veliko več dnevnih ogledov, a moramo vedeti, da mi ponujamo daljša, 45-minutna predavanja. Najbolj gledana so predavanja s področja računalništva. Največ obiskov imamo iz ZDA, Indije, Kitajske, Nemčije, Velike Britanije pa tudi iz Slovenije. Obiskujejo nas iz večjih mest, kjer so univerze – London, Ljubljana, New York, pa tudi kjer so raziskovalni centri.
  • VideoLectures.Net ni profitni projekt, zato smo že tukaj omejeni s finančnimi prilivi. Pod okriljem inštituta smo finančno samozadostni in neodvisni, predvsem zaradi raziskovalnih projektov, ki potrebujejo naše storitve

A 'more revolutionary' Web - The New York Times - 0 views

  • Just when the ideas behind "Web 2.0" are starting to enter into the mainstream, the mass of brains behind the World Wide Web is introducing pieces of what may end up being called Web 3.0. "Twenty years from now, we'll look back and say this was the embryonic period," said Tim Berners-Lee, 50, who established the programming language of the Web in 1989 with colleagues at CERN, the European science institute.
  • To many in technology, Web 2.0 means an Internet that is even more interactive, customized, social and media-intensive - not to mention profitable - than the one of a decade ago.It is a change apparent with multilayered media databases like Google Maps, software programs that run inside Web browsers like the collaboration-friendly word processor Writely, high-volume community forums like MySpace, and so-called social search tools like Yahoo Answers.
  • In this version of the Web, sites, links, media and databases are "smarter" and able to automatically convey more meaning than those of today.For example, Berners-Lee said, a Web site that announces a conference would also contain programming with a lot of related information embedded within it.A user could click on a link and immediately transfer the time and date of the conference to his or her electronic calendar. The location - address, latitude, longitude, perhaps even altitude - could be sent to his or her GPS device, and the names and biographies of others invited could be sent to an instant messenger list.

  • "There is an obvious place for the semantic Web in life sciences, in medicine, in industrial research," Shadbolt said, and that is where most of the focus is today."We're looking for communities of information users to show them the benefits," he said. "It's an evolutionary process."The big question is whether it will move on next to businesses or consumers, he said. A consequence of an open and diffuse Internet, he noted, is that unexpected outcomes can emerge from unanticipated places.
  • "People keep asking what Web 3.0 is," Berners-Lee said. "I think maybe when you've got an overlay of scalable vector graphics - everything rippling and folding and looking misty - on Web 2.0 and access to a semantic Web integrated across a huge space of data, you'll have access to an unbelievable data resource."Said Sheehan: "I believe the semantic Web will be profound. In time, it will be as obvious as the Web seems obvious to us today."

  • Za sve one koji negativni utjecaj iz elektroničkih uređaja smatraju običnom teorijom zavjere bez ikakve veze s istinom donosimo najnovija znanstvena otkrića koja pokazuju vezu između novootkrivenih svojstava deoksiribonukleinske kiseline i bežičnih tehnologija.
  • DNK ima dvije strukturalne karakteristike fraktalnih antena: elektroničku kondukciju i samo-simetriju.
  • Kada se DNK našla u doticaju s EMF-om i RF-om, prvo su se pojavili visoki nivoi stresnih proteina u heliskima DNK, a nakon toga su znanstvenici promatrali kako se spirale DNK razdvajaju i raspadaju. Drugim riječima ne-ionizrajuće zračenje uništava ljudsku DNK.

  • Ljudska DNK je najburnije reagirala na ELF-ove (extreme low frequencies) ili radio valove ekstremno niske frekvencije, iako su efekti slični kao i s drugim oblicima RF i EMF zračenja, u slučaju ELF-ova reakcije su postajale puno kompleksnije.
  • povećanje različitih vrsta zračenja siguran razlog u povećanju kancerogene epidemiologije
  • povećanje broja kancerogenih oboljenja možemo zahvaliti različitim zračenjima iz okoliša koja su oštetila i još uvijek oštećuju našu DNK.
  • za 40% povećava rizik od dobivanja raka mozga u slučaju da korisnici provedu telefonirajući više od 1640 sati. U neovisnom istraživanju iz 2007., godine, koje je obavio tim iz Švedske je otkriveno kako se za 540% povećava rizik od dobivanja raka ako se mobilni telefoni koriste više od 2000 sati.
  • Svijet se treba osloboditi od mobilne telefonije, ne samo da je ova tehnologija opasna, ona je smrtonosna. Biološki učinak mobilnih telefona na ljudsko tijelo ne leži u jakosti signala već u njegovoj eratičnoj prirodi koja uništava rezonancu DNK i njenu mogućnost obnavljanja. Ovo je i najjednostavniji razlog zašto mobilna tehnologija stvara kancerogena oboljenja.
  • Izraelski znanstvenici su preko 30 godina istraživali povećanje tumora na parotidnoj žlijezdi, između 1970-te i 2006-te godine broj tumora se povećao za 400%.
  • dr. Siegal Sadetcki, glavni istražitelj senata SAD-a, je uspio identificirati glavnog krivca za tumore zaušne žlijezde. U njegovom izvješću stoji kako su mobilni telefoni glavni i najčešći krivci za: 34% povećanja rizika od tumora zaušne žlijezde ako se mobilni telefon koristi na regularnoj bazi u vremenu od pet godina. 58% povećanja rizika od tumora zaušne žlijezde ako se mobilni telefon koristi s više od 5500 poziva za vrijeme ljudskog života. 49% povećanja rizika od tumora zaušne žlijezde ako se mobilni telefon koristi za više od 266,3 sata za vrijeme ljudskog života.
  • 03.05.2011., godine, WHO i IARC (International Agency for Research on Cancer) ili Internacionalna agencija za istraživanja raka, su priznale kako mobilna telefonija zaista uzrokuje rak, te su zračenje iz mobilnih telefona stavili u 2B rizičnu skupinu za ljude.
  • U istraživanju koje je objavljeno 2008., godine je otkriveno kako su trudnice i njihova nerođena djeca posebno osjetljiva na zračenje iz mobitela. Znanstvenici su analizirali 13 tisuća djece i otkrili su kako je zračenje iz bežične tehnologije uzrokovalo brojne probleme za vrijeme trudnoće te da je na koncu povećalo rizik od poremećaja koji izazivaju hiperaktivnost, nedostatak pažnje, probleme s emocijama, stvaranjem i održavanjem veza s ljudima i druge bihevioralne anomalije. Rizik je postajao još veći ako su djeca koristila mobilne telefone prije navršene sedme godine života. Sve trudnice koje su koristile mobilne telefone su imale 54% povećan rizik od različitih fizičkih i psihičkih anomalija u zdravlju i razvoju njihove djece.
  • U nedavnim istraživanjima se potvrdilo kako su djeca, pa čak i ona nerođena u najvećoj opasnosti od zračenja uzrokovanog bežičnom tehnologijom i mobilnim telefonima.
  • osobe koje su počele koristiti mobitel kao tinejdžeri imaju 400-500% veću mogućnost od razvijanja raka mozga u dobi od 20-te do 30-te godine.
  • U znanstvenom istraživanju koje je objavljeno 2009., godine se pokazalo kako nošenje mobitela u džepu hlača uništava kosti karlice, točnije stvara osteoporozu. Muškarci koji su nosili mobitele okačene o opasač ili unutar džepa od hlača su unutar šest godina ove prakse izgubili gustoću kostiju karlice.
  • RF-EMR (radio frekvencije i elektromagnetsko zračenje) bez obzira na jakost i frekvenciju mobilnih telefona, uništava mitohondrijsku generaciju kisika unutar ljudskih spermija, na taj se način smanjuje njihova pokretljivost, dok s druge strane uništava DNK i fragmentira je. Ovo istraživanje ima jasnu implikaciju o tome koliko je opasno korištenje mobilnih telefona za muškarce koji imaju namjeru imati djecu. Mobiteli potencijalno utječu na plodnost muškaraca i zdravlje njihovih potomaka.
