BBC News - Google previews Chrome open source operating system - 0 views

  •  
    Google is going after Microsoft with their new open source operating system designed originally for netbook users - so no software has to be installed.  It is all browser based and stores docs on Google servers - great for computer crashes - security???

When expected network reliability and security goes awry - 1 views

    This opinion article attacks RIM (Blackberry) for the outage fiasco experienced earlier this week and it got me thinking about the server outages, latency, bandwidth issues that schools face routinely even when trying to upgrade their infrastructure to meet the demands of today's technology. If education adopts mobile devices as essential or central tools in the formal learning space, how might the frequency of "dead zones" or transmittal issues effect the synchronous advantage of using such devices in class? If RIM had issues, I guess maybe it just adds one more layer of complexity and consideration to the integration of mobile technology into the classroom that will have to be accounted for and more importantly - tolerated?

    While this is a factor to consider, we must consider the frequency of such outages.

    Does anyone have any experience with this tool. It looks like a very interesting example of a Intelligent Web Filtering. Wow! Good side is that this is like Tivo for the web. Bad side is that you better have nothing else to do but look at the web. Also an interesting take on Personal Learning Networks.

    I am familiar with BitTorrent, and it's interesting Chris that you came about it excited for its uses in education. But have you read or heard about the controversy surrounding it? In a nutshell- BitTorrent is a technology that allows large collections of files and data to be shared across the internet in a decentralized, peer-to-peer manner. A person who has the original files decides to share them via BitTorrent, so others can download from him/her. But as the others begin downloading the files, they also start sharing the pieces they've downloaded with the ever-growing set of new users asking for the file. BitTorrent works like a growing web- in order to download files shared via BitTorrent - you have to share the pieces you get with others. More downloaders = more uploaders as well, ensuring popular files will always be accessible. The benefits - this is cheap and decentralized, no need to pay to host the files on the web. The users who have the file are sharing the file from their own computers with others requesting it. And this can be permanent - if you host a BitTorrent to share a file, you have that sharing channel last forever (not relying on external services that cost $ or can be shut down).

    BitTorrent is a really powerful technology that allows large amounts of files and data to be shared quickly with a limitless number of people. It's scalability at no cost. Could be a great tool for educators to share content across the globe in a hassle-free way. Even the folks at Khan Academy are excited to use it: from: http://blog.vipeers.com/vipeers/2008/10/bittorrent-is-a.html "For Khan Academy, BitTorrent was a natural extension for it stated mission of "a world-class education for anyone anywhere," Sal Khan tells Fast Company. Kahn was excited for activist educators to be able to download the Academy's entire portforlio, burn it on a CD, and distribute it to rural or underdeveloped areas otherwise unable to access it without a broadband connection. "I think the single most fun thing about BitTorrent," Khan adds, "is this content will never die. A nuclear bomb could hit our offices tomorrow and could take down our servers, but its going to sitting somewhere in the world on somebody's server." He added, "We don't care about monetizing the content; we just care that it gets used."

    But despite the prospects of BitTorrent being a great technology to allow sharing of digital content freely, to allow downloading of vast amounts of data that can then be stored offline and shared with anyone... the rest of the article (http://blog.vipeers.com/vipeers/2008/10/bittorrent-is-a.html) mentions that Google was unhappy with Khan's decision to use BitTorrent. Google actually blacklists BitTorrent content from its searches, and so is actually blacklisting Khan Academy content, despite being a recent financial backer of Khan. Why? This is the controversy: BitTorrent's power to share digital content in a decentralized way, where the more popular a file is, the faster it'll spread-- has led it to become the most popular method of digital piracy out there today. This has quickly become the most common use of BitTorrent, far exceeding the sharing of legitimate digital content. It's become a nightmare for the movie, music, software, and video gaming industries. A summary of the legal issues surrounding BitTorrent: http://en.wikipedia.org/wiki/Legal_issues_with_BitTorrent

    Hey Bharat, I am so glad I asked. I had no idea. Very interesting. New dimension to the concept of free knowledge vs. intellectual property. I think the kids at my school are using this to share music. I'll have to check it out. I find this conflict- "Google actually blacklists BitTorrent content from its searches, and so is actually blacklisting Khan Academy content, despite being a recent financial backer of Khan. " so intriguing. At first glance it looked to me like a vision of networked learning that was aimed at an authentic task with authentic participants (as portrayed by actors :).

Kids Tagged With RFID Chips? The Creepy New Technology Schools Use to Track Everything ... - 2 views

  •  
    In general, these systems consist of a school photo ID card affixed to a lanyard that is worn around the student's neck. The ID has a RFID chip embedded in it. The tag includes a digit number assigned to each student. As a student enters the school or pass beneath a doorway equipped with an RFID reader, the tag ID is read, recorded and sent to a server in the school's administrative office. The captured data not only provides an attendance list (sent to the teacher's PDA), but tracks the student's movement throughout the day.

    I like that it makes attendance easier to monitor but still seems kinda creepy...and there's always a way around those systems....

Offline Learning - 1 views

  •  
    The Foundation for Learning Equality is working to get content to the 65% of the world who live without internet. Currently their only project involves offlining Khan Academy lectures and loading them on SD cards which can be loaded onto Raspberry Pi servers and sent along with e-readers to anywhere in the world. To me, this seems like an incredible opportunity to simultaneously address quality and access issues in remote parts of the world, though I don't think Khan Academy's content is necessarily the best. As a technological innovation, however, I think there is a real possibility to scale this, insofar as there are on-the-ground resources in each location facilitating the learning on the e-readers. Does anybody have any critique or insight to curb my excitement?

The Web Is Dead. Long Live the Internet | Magazine - 2 views

  • a good metaphor for the Web itself, broad not deep, dependent on the connections between sites rather than any one, autonomous property.
  • According to Compete, a Web analytics company, the top 10 Web sites accounted for 31 percent of US pageviews in 2001, 40 percent in 2006, and about 75 percent in 2010. “Big sucks the traffic out of small,” Milner says. “In theory you can have a few very successful individuals controlling hundreds of millions of people. You can become big fast, and that favors the domination of strong people.”
  • This was all inevitable. It is the cycle of capitalism. The story of industrial revolutions, after all, is a story of battles over control. A technology is invented, it spreads, a thousand flowers bloom, and then someone finds a way to own it, locking out others. It happens every time.

  • Google was the endpoint of this process: It may represent open systems and leveled architecture, but with superb irony and strategic brilliance it came to almost completely control that openness. It’s difficult to imagine another industry so thoroughly subservient to one player. In the Google model, there is one distributor of movies, which also owns all the theaters. Google, by managing both traffic and sales (advertising), created a condition in which it was impossible for anyone else doing business in the traditional Web to be bigger than or even competitive with Google. It was the imperial master over the world’s most distributed systems. A kind of Rome.
  • Enter Facebook. The site began as a free but closed system. It required not just registration but an acceptable email address (from a university, or later, from any school). Google was forbidden to search through its servers. By the time it opened to the general public in 2006, its clublike, ritualistic, highly regulated foundation was already in place. Its very attraction was that it was a closed system. Indeed, Facebook’s organization of information and relationships became, in a remarkably short period of time, a redoubt from the Web — a simpler, more habit-forming place. The company invited developers to create games and applications specifically for use on Facebook, turning the site into a full-fledged platform. And then, at some critical-mass point, not just in terms of registration numbers but of sheer time spent, of habituation and loyalty, Facebook became a parallel world to the Web, an experience that was vastly different and arguably more fulfilling and compelling and that consumed the time previously spent idly drifting from site to site. Even more to the point, Facebook founder Mark Zuckerberg possessed a clear vision of empire: one in which the developers who built applications on top of the platform that his company owned and controlled would always be subservient to the platform itself. It was, all of a sudden, not just a radical displacement but also an extraordinary concentration of power. The Web of countless entrepreneurs was being overshadowed by the single entrepreneur-mogul-visionary model, a ruthless paragon of everything the Web was not: rigid standards, high design, centralized control.
  • Blame human nature. As much as we intellectually appreciate openness, at the end of the day we favor the easiest path. We’ll pay for convenience and reliability, which is why iTunes can sell songs for 99 cents despite the fact that they are out there, somewhere, in some form, for free. When you are young, you have more time than money, and LimeWire is worth the hassle. As you get older, you have more money than time. The iTunes toll is a small price to pay for the simplicity of just getting what you want. The more Facebook becomes part of your life, the more locked in you become. Artificial scarcity is the natural goal of the profit-seeking.
  • Web audiences have grown ever larger even as the quality of those audiences has shriveled, leading advertisers to pay less and less to reach them. That, in turn, has meant the rise of junk-shop content providers — like Demand Media — which have determined that the only way to make money online is to spend even less on content than advertisers are willing to pay to advertise against it. This further cheapens online content, makes visitors even less valuable, and continues to diminish the credibility of the medium.

The Situation - Television Tropes & Idioms - 0 views

  • Google pulled all their ads on October 26th, due to TOS violations on the part of the wiki and forums — specifically "adult and mature content" on pages that carried Google Adsense ads. These ads provided far and away the majority of the site's operating budget.
  • Turn off anonymous editing in the wiki. This is so that we can tell Google, "See, we do have standards, and we can identify and take action against people who violate them." This has already been implemented.
  • Segregate "adult and mature content" behind some sort of barrier that you will have to explicitly agree to go through. This has been implemented

  • Nofollow tags will be attached to outbound links on wiki pages. This is an invisible-to-users tag that tells the Ad Server "The following link goes somewhere that isn't us. Don't hold us responsible for their content."

    TV Tropes is being very transparent about creating a moderation system for the content. This is in response to loosing advertising dollars from Google. It is interesting to see the outline for their model of moderating content. Some of these elements could be used in a web 2.0 environment for education

India's $35 tablet is here, for real. Called Aakash, costs $60 -- Engadget - 3 views

  •  
    Tying into discussions this week about bringing access to mobile devices to all via non-prohibitive costs, while still reaching a set of bare-minmum technical specs for actual use: India's "$35 tablet" has been a pipedream in the tech blog-o-sphere for awhile now, but it's finally available (though for a price of roughly $60). Still though, as an actual Android color touch tablet, with WiFi and cellular data capability - I'm curious to see how it's received and if it's adopted in any sort of large scale

    I had heard months ago that India was creating this, but was not going to offer it commercially - rather, just for its own country. Just like the Little Professor (Prof Dede) calculator, when tablets get this affordable, educational systems can afford classroom sets of them and then use them regularly. But to Prof Dede's point - can they do everything that more expensive tablets can do? Or better yet - do they HAVE to?
  •  
    I think this is what they're aiming to do - all classrooms/students across the country having this particular tablet. They won't be able to do everything today's expensive tablets can do, but I think they'll still be able too to do plenty. This $35 tablet's specs are comparable to the mobile devices we had here in the US in 2008/2009. Even back then, we were able to web browse, check email, use social networking (sharing pics and video too), watching streaming online video, and play basic 2D games. But even beyond those basic features, I think this tablet will be able to do more than we expect from something at this price point and basic hardware, for 2 reasons: 1. Wide-spread adoption of a single hardware. If this thing truly does become THE tablet for India's students, it will have such a massive userbase that software developers and designers who create educational software will have to cater to it. They will have to study this tablet and learn the ins-and-outs of its hardware in order to deliver content for it. "Underpowered" hardware is able to deliver experiences well beyond what would normally be expected from it when developers are able to optimize heavily for that particular set of components. This is why software for Apple's iPhone and iPad, and games for video game consoles (xbox, PS3, wii) are so polished. For the consoles especially, all the users have the same exact hardware, with the same features and components. Developers are able to create software that is very specialized for that hardware- opposed to spending their resources and time making sure the software works on a wide variety of hardware (like in the PC world). With this development style in mind, and with a fixed hardware model remaining widely used in the market for many years- the resultant software is very polished and goes beyond what users expect from it. This is why today's game consoles, which have been around since 2005/6, produce visuals that are still really impressive and sta
