  • Google is not only the world's largest search engine, it's one of the top three email providers, a social network, and owner of the Blogger platform and the world's largest video site, YouTube. Facebook has the social contacts, messages, wallposts and photos of more than 750 million people.
  • The site also lists my most recent sent and received emails (in both cases a "no subject" conversation thread with a colleague).
  • The big relief comes when I note Google isn't tracking the internet searches I've made on my work account
  • ...12 more annotations...
  • only around 29% of the information Facebook possesses on any given user is accessible through the site's tools.
  • The Facebook extended archive is a little creepier, including "poke info", each instance of tracking cookies they possess, previous names, and full login and logout info
  • Looking through anyone's list of searches gives a distressing degree of insight into odder parts of their personality.
  • sell us stuff
  • how much do the internet giants really know?
  • picked up by hackers
  • how much the internet giants know about us.
  • Google isn't totally unhelpfu
  • Every event to which I've ever been invited is neatly listed, alongside its location, time, and whether I said I would attend .
  • One piece of information – a supposed engagement to a schoolfriend, Amy Holmes – stands out. A Facebook "joke" that seemed faintly funny for about a week several years ago was undone by hiding it from any and all Facebook users, friends or otherwise (to avoid an "… is now single!" status update). The forgotten relationship helpfully explains why Facebook has served me up with badly targeted bridalwear adverts for several years, and reassures me that Facebook doesn't know quite everything.
  • This is the core of the main comfort
  • despite their mountain of data, Google and Facebook seem largely clueless, too – they've had no more luck making any sense out of it than I have. And that, for now, is a relief.

  • Only about 5% of retailers currently have the interest or the ability to market to specific customers based on their location, according to Ingle. Most of what brands are interested in is more generalized information about their customers. But in a rapidly evolving and increasingly mobile marketplace, the brands that arrive late to the location-based targeted advertising game may be left out in the cold.
  • Your smartphone holds a treasure trove of information about you, and cell phone companies are looking for ways to turn that into profit.
  • "An interesting transformation is happening in wireless, in which consumers are no longer customers -- they're the product," said Dan Hays, principal in PricewaterhouseCooper's communications and technology practice. "The trick is for operators to find out how to make money without violating their relationships and trust with their users."

Forty years of the internet: how the world changed for ever | Technology | The Guardian - 1 views

history web changed world

  • In October 1969, a student typed 'LO' on a computer - and the internet was born
  • Towards the end of the summer of 1969
  • a large grey metal box was delivered to the office of Leonard Kleinrock, a professor at the University of California in Los Angeles.
  • ...32 more annotations...
  • At 10.30pm, as Kleinrock's fellow professors and students crowded around, a computer was connected to the IMP, which made contact with a second IMP, attached to a second computer, several hundred miles away at the Stanford Research Institute, and an undergraduate named Charley Kline tapped out a message.
  • It's impossible to say for certain when the internet began, mainly because nobody can agree on what, precisely, the internet is.
  • It's interesting to compare how much has changed in computing and the internet since 1969 with, say, how much has changed in world politics.
  • On the other hand, the breakthrough accomplished that night in 1969 was a decidedly down-to-earth one
  • Twelve years after Charley Kline's first message on the Arpanet, as it was then known, there were still only 213 computers on the network; but 14 years after that, 16 million people were online, and email was beginning to change the world; the first really usable web browser wasn't launched until 1993, but by 1995 we had Amazon, by 1998 Google, and by 2001, Wikipedia, at which point there were 513 million people online. Today the figure is more like 1.7 billion.
  • on New Year's Day 1994 – only yesterday, in other words – there were an estimated 623 websites.
  • On the one hand, they were there because of the Russian Sputnik satellite launch, in 1957, which panicked the American defence establishment, prompting Eisenhower to channel millions of dollars into scientific research, and establishing Arpa, the Advanced Research Projects Agency, to try to win the arms technology race. The idea was "that we would not get surprised again,"
  • "In a few years, men will be able to communicate more effectively through a machine than face to face," they declared.
  • The few outsiders who knew of the box's existence couldn't even get its name right: it was an IMP, or "interface message processor"
  • It was already possible to link computers by telephone lines, but it was glacially slow, and every computer in the network had to be connected, by a dedicated line, to every other computer, which meant you couldn't connect more than a handful of machines without everything becoming monstrously complex and costly.
  • The solution, called "packet switching" – which owed its existence to the work of a British physicist, Donald Davies – involved breaking data down into blocks that could be routed around any part of the network that happened to be free, before getting reassembled at the other end.
  • Still, Kleinrock recalls a tangible sense of excitement that night as Kline sat down at the SDS Sigma 7 computer, connected to the IMP, and at the same time made telephone contact with his opposite number at Stanford. As his colleagues watched, he typed the letter L, to begin the word LOGIN.
  • One of the most intriguing things about the growth of the internet is this: to a select group of technological thinkers, the surprise wasn't how quickly it spread across the world, remaking business, culture and politics – but that it took so long to get off the ground.
  • In 1945, the American presidential science adviser, Vannevar Bush, was already imagining the "memex", a device in which "an individual stores all his books, records, and communications", which would be linked to each other by "a mesh of associative trails", like weblinks.
  • And in 1946, an astonishingly complete vision of the future appeared in the magazine Astounding Science Fiction. In a story entitled A Logic Named Joe, the author Murray Leinster envisioned a world in which every home was equipped with a tabletop box that he called a "logic":
  • Instead of smothering their research in the utmost secrecy – as you might expect of a cold war project aimed at winning a technological battle against Moscow – they made public every step of their thinking, in documents known as Requests For Comments.
  • Deliberately or not, they helped encourage a vibrant culture of hobbyists on the fringes of academia – students and rank amateurs who built their own electronic bulletin-board systems and eventually FidoNet, a network to connect them to each other.
  • n argument can be made that these unofficial tinkerings did as much to create the public internet as did the Arpanet. Well into the 90s, by the time the Arpanet had been replaced by NSFNet, a larger government-funded network,
  • It was the hobbyists, making unofficial connections into the main system, who first opened the internet up to allcomers.
  • This was the software known as TCP/IP, which made it possible for networks to connect to other networks, creating a "network of networks", capable of expanding virtually infinitely
  • Nevertheless, by July 1992, an Essex-born businessman named Cliff Stanford had opened Demon Internet, Britain's first commercial internet service provider.
  • After a year or so, Demon had between 2,000 and 3,000 users,
  • the @ symbol was introduced in 1971, and the first message, according to the programmer who sent it, Ray Tomlinson, was "something like QWERTYUIOP".
  • A couple of years later I got my first mobile phone, which came with two batteries: a very large one, for normal use, and an extremely large one, for those occasions on which you might actually want a few hours of power
  • For most of us, though, the web is in effect synonymous with the internet, even if we grasp that in technical terms that's inaccurate: the web is simply a system that sits on top of the internet, making it greatly easier to navigate the information there, and to use it as a medium of sharing and communication.
  • The first ever website was his own, at CERN: info.cern.ch.
  • The idea that a network of computers might enable a specific new way of thinking about information, instead of just allowing people to access the data on each other's terminals, had been around for as long as the idea of the network itself: it's there in Vannevar Bush's memex, and Murray Leinster's logics.
  • Web browsers crossed the border into mainstream use far more rapidly than had been the case with the internet itself: Mosaic launched in 1993 and Netscape followed soon after, though it was an embarrassingly long time before Microsoft realised the commercial necessity of getting involved at all. Amazon and eBay were online by 1995. And in 1998 came Google, offering a powerful new way to search the proliferating mass of information on the web.
  • Google, and others, saw that the key to the web's future would be helping users exclude almost everything on any given topic, restricting search results to the most relevant pages.
  • It is absurd – though also unavoidable here – to compact the whole of what happened from then onwards into a few sentences: the dotcom boom, the historically unprecedented dotcom bust, the growing "digital divide", and then the hugely significant flourishing, over the last seven years, of what became known as Web 2.0.
  • The most confounding thing of all is that in a few years' time, all this stupendous change will probably seem like not very much change at all.
  • Will you remember when the web was something you accessed primarily via a computer? Will you remember when there were places you couldn't get a wireless connection? Will you remember when "being on the web" was still a distinct concept, something that described only a part of your life, instead of permeating all of it? Will you remember Google?

  • Comment is free The internet comes of age Older people are using the web as never before.
  • Silver surfers, defined as internet users over the age of 65, spend more time on the web (42 hours a month) than any other group,
  • A lot of older people still do not realise that once you have fixed up a broadband connection (which admittedly can be dodgy with some service providers) it is very easy to buy or sell things on the auction space eBay (the most popular one in the UK); to buy a book from Amazon or the wonderful abebooks; or to Google or email.

Kako internet i nove tehnologije utječu na pažnju i koncentraciju kod djece? ... - 0 views

  • Nema uopće sumnje da nove tehnologije, predvođene internetom, oblikuju naše razmišljanje i načine na koje razmišljamo.
  • Nema uopće sumnje da nove tehnologije, predvođene internetom, oblikuju naše razmišljanje i načine na koje razmišljamo. Ponekad se to događa vidno i neposredno, gotovo namjerno, a ponekad suptilno i slučajno.
  • tehnološki bum događa se tako brzo da nemamo vremena ispitati i razmisliti njegovu vrijednost u odnosu na cijenu koju djeca plaćaju i obratno.
  • ...11 more annotations...
  • Tehnologija utječe na stvaranje drugačijih veza i drugačije povezivanje informacija u dječjem mozgu nego što je to bilo kod prošlih generacija.
  • Ono što je jasno znanstvenicima je da svaki napredak tijekom povijesti, odnosno nova dostupna tehnologija određuje kako će se razvijati mozak kod ljudi.
  • Hoće li tehnologija pomoći ili odmoći razvoju vašeg djeteta i načinima na koje razmišlja, ovisi koju specifičnu tehnologiju koristi, koliko često i na koji način.
  • Osim na usvajanje informacija, donošenje odluka i pamćenje (učenje), nove tehnologije imaju najveći utjecaj na pažnju kod djece.
  • U starijim generacijama, primjerice, djeca su veliki dio vremena posvećivala čitanju, a to je aktivnost u kojoj nema puno odvlačenja pažnje te zahtijeva intenzivnu i postojanu pažnju, maštu i pamćenje. Tu pažnju prekinula je televizija koja je novoj generaciji djece ponudila vizualnu stimulaciju, a za uzvrat tražila rascjepkanu pažnju i gotovo nikakvu maštu. Internet generacija s razvojem tehnologije našla se pred novim izazovima. Potpuno nova virtualna okolina djeci je ponudila svijet u kojem je odvlačenje pažnje na sve strane gotovo norma. Postojana pažnja je nemoguća, mašta je potpuno nepotrebna, a pamćenje ograničeno.
  • tehnologija uvjetuje mozgu da pažnju pridaje informacijama na potpuno drugačiji način od čitanja.
  • Čitanje knjige je poput ronjenja tijekom kojeg je osoba uvučena u tihi, vizualno ograničeni svijet, u kojem vrijeme prolazi sporije i bez nekih većih prekida pažnje. Rezultat je ravnomjerna pažnja i fokus te duboko razmišljanje o ograničenom broju primljenih informacija. S druge strane, korištenje interneta je poput jet-skija tijekom kojeg skijaš skija po površini velikom brzinom, izložen je širokom rasponu prizora, okružen mnogim distrakcijama i ne može se ozbiljnije fokusirati ni na jednu informaciju.
  • Studije su potvrdile da čitanje neprekinutog, ujednačenog teksta rezultira bržim završavanjem i boljim razumijevanjem, boljim prisjećanjem pročitanog i učenjem, u uskoredbi s čitanjem teksta koji je prošaran hiperlinkovima, oglasima i drugim ukrasima kakve nalazimo u tekstovima na internetu. Isto vrijedi i za prezentacije.
  • Još jedna studija pokazala je da su djeca koja su tijekom nastave imala pristup internetu zaboravila o čemu je bila tema predavanja i slabije su riješili testove od vršnjaka koji nisu tijekom nastave bili online.
  • Neka druga istraživanja pokazuju da, primjerice, neke video igrice i drugi sadržaji poboljšavaju vizualno-spacijalne sposobnosti, vrijeme reakcije na podržaje i sposobnost da se uoči detalj i izdvoji ono što je važno. Tehnologija djecu ne čini glupljima, već drugačijima.
  • Dok vrijeme ne pokaže kako će nove tehnologije i ubrazani razvoj promijeniti način razmišljanja kod naše djece, ono što roditelji mogu je dozirati stara i nova okruženja u odrastanju djece. Djeci treba ograničiti vrijeme provedeno pred ekranom i poticati ih na aktivnosti poput čitanja, maštanja i slobodne nestrukturirane igre.

  • 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.
  • ...10 more annotations...
  • 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
