Video: Richard Stallman talks about the importance of free software, GNU, copyleft and open sourcing

In these videos, Robin Good interviews Richard Stallman about free software and the open source movement. Stallman created the GPL and the Free Software Foundation to protect the GNU operating system from becoming proprietary.

In the sequence embedded below, filmed, the founding father of open source software answers a series of questions. This interview was originally posted at MasterNewMedia.org in 2006 and features commentary and links from Robin Good.

Q: What is free software?

Q: What are the negative consequences of using proprietary software instead of free software?

Q: What free software do you recommend using?

Q: Can individuals and organizations use GNU/Linux in their daily operations?


Q: What can individuals do to support the open source movement?

Video: How to install the Cosmos User Kit

This video from GoCosmos.org demonstrates how to install the Cosmos User Kit.

Cosmos is an open source microkernel .Net-based operating system written entirely in C#. The folks over at SharpOS.org, who have also created a microkernel OS written in C#, have reasonably objected to claims that Cosmos is the first OS of this type. Both operating systems can be installed and run from a USB jump drive, which only adds to their geeky cred.

You can get updates to the Cosmos project at the official blog. A Cosmos FAQ is also available at the site.

Better Education Through Open Source Robots

Heather Johnson is guest blogging at WhatIs.com this week. Heather is a freelance writer, as well as a monthly contributor for OEDb, a site that helps students select among accredited online schools. She invites comments and freelancing job inquiries at heatherjohnson2323@gmail.com.

There has been a lot of talk about open source hardware lately and its potential effects on research and education. ETech 2008 showcased many examples of open hardware and offered an insightful presentation [PDF] to those who are new to the emerging technology. Likewise, popular sites like Slashdot and bloggers like Scobleizer have been discussing the growing movement.

The increasing popularity of open source software has already had a tremendous influence on education and the world as a whole. Not only are many schools now making the switch to open source programs, leading universities like UC Berkeley and Carnegie Mellon are involved with developing large open source software projects.

A Scribbler Robot with BluetoothHowever, we have yet to see open hardware really take off. Ryan Singel of Wired feels that 2008 could be the year and I second that opinion. Leading the pack seems to be open source robotics, which has been embraced by several major universities.

Just last month, Willow Garage’s Steve Cousins gave a keynote speech at ETech 2008 about open source personal robots, which has brought more attention to the subject. Willow Garage is a privately funded lab that experiments with various robotics platforms.

This open source robotics movement can be felt on many college campuses as well. Carnegie Mellon, which I previously stated is involved with open source software, is also building OS personal robots. The university has recently formed a joint project called the Institute for Personal Robots in Education (IPRE).

The IPRE is a joint project between Georgia Tech and Bryn Mawr College, with sponsorship provided by Microsoft Research. Its purpose is to help advance robotics research and computer science education. The IPRE is currently selling open source robot kits, which are geared toward educators and can be integrated with computer education curricula.

Video: Exploring presence technology with tele-immersive dance in cyberspace

Often the title of a video alone raises an eyebrow. Today’s video selection certainly does — it’s a presentation from two tele-immersion labs, one at UC Berkeley’s Center for Information Technology Research in the Interest of Society (CITRIS) and the other within the University of Urbana-Champaign Computer Science Department. According to the IEEE Computer Society, tele-immersion is when “collaborators at remote sites share the details of a virtual world that can autonomously control computation, query databases, and gather results.” It might be a stretch but I see tele-immersion used in that was as an advanced version of presence technology, in which an application make it possible to locate and identify a computing device wherever it might be, as soon as the user connects to the network.

As it’s a dance performance, both labs worked in close collaboration with the Department of Theater, Dance, and Performance Studies at UC Berkeley, and the Dance Department and Intermedia Program at Mills College. The video quality admittedly isn’t great — and you may want to skip ahead to 11:30, when the actual performance begins, or to 20:00, when the dancing starts — but the concept itself is noteworthy for its aspiration to bridge the gap between real and virtual environments.


From the show notes on YouTube:

The Resonance Project Dance Group performed for a very large crowd in the Hearst Memorial Mining Building at UC Berkeley. The performance was a blend of live, modern dance with live tele-immersed dancers from University of Illinois in Urbana-Champaign, Illinois. Using a large network of cameras and computers the dancers were able to span the geographic distance and mingle in cyberspace. The computers merged three-dimensional video images of the dancers onto a single projection, which was broadcast alongside live dancers.

The Resonance Project is a team of choreographers, dancers, computer engineers, and visual and sound artists who are investigating concepts of presence/remote presence and corporeal and code interactivity within live and media based performance. Unique to the project is the use of a “performance as research” model, within which scientists and artists collaborate to explore a re-visioning of cyber culture and corporeal presence.

The nature of the performance has a close conceptual relationship with CAVE, a tele-immersive environment used for learning in a wide variety of disciplines, and the CAVEman, the first 4-D human atlas.

Video: Ted Nelson, hypertext and the Web

In this Google TechTalk, Ted Nelson discusses implementing the original hypertext concept and how transclusion should be used now to fulfill its original potential.

While Nelson is credited with coining the term “hypertext, Vannevar Bush is responsible for inventing the concept, which he described as “instant cross referencing.”

As usual, we tread in the path of giants.

Video: How to log into websites using OpenID

One of our newest definitions explains OpenID:

“OpenID is a decentralized single sign-on authentication system for the Internet. The goal of the OpenID initiative is to allow users to log in at websites around the Internet with one ID instead of having to create multiple unique accounts. OpenID was developed using the open source software model to be an interoperable protocol independent from any single organization. (Continued…)”

Activating and using an OpenID is quite easy — I was able to sign up for TravelWiki, for instance, using one from Yahoo!. Activation and setup took about a minute. I’ve embedded three videos below that explain more about how OpenID works and how to use it. Enjoy!

The video below explains more about how to use an OpenID to login, in this case to votay.com:

Here’s another one that explains how to use OpenID with WordPress:

Dave provides a short, clear explanation of OpenID using a whiteboard here:

And finally, in a Google TechTalk, Simon Willison  (co-creator of the Django Web framework) discusses the implications of OpenID and explores the best practices required to take advantage of the new technology while avoiding the potential security pitfalls. This one’s a bit long but excellent. 

The Singularity: Creating smarter-than-human intelligence through high technology

This past weekend, many of the world’s foremost thinkers gathered at the Singularity Summit within the Palace of Fine Arts in San Francisco. You might ask what the Singularity is, of course, as the focus of all of this heady cogitation?

It’s the point where a consciousness is comes into being (usually an AI) that is itself smarter than the humans who created it.

According to the Summit’s overview:

Vernor Vinge originally coined the term “Singularity” in observing that, just as our model of physics breaks down when it tries to model the singularity at the center of a black hole, our model of the world breaks down when it tries to model a future that contains entities smarter than human.

The summit’s Web site features videos, podcasts and coverage from all over the Internet of the yearly event, including a great piece from Peter Thiel on Wired.com exploring how to invest in the Singularity.

I can’t help but think of SkyNet, the decidedly nasty entity depicted so dramatically in the Terminator series, but there are more positive outcomes, many of which are amply explained here, where the summit’s organizers explain why the Singularity is worth working towards.  Whether humanity is willing or able to do so is another question entirely. We can only hope!

Speaking from a somewhat philosophical perspective, Joe Foran also had some deep thoughts regarding the concept, articulated in Virtualization and the Singularity on the Server Virtualization blog. If you’re wondering how virtualization and futurism blend together, look no further.

Facebook: A social network evolves into a social utility

What can I say about Facebook that hasn’t been said? Newsweek has placed Mort Zuckerberg, the founder of the social networking giant on its cover. And the press has been hyperventilating about Facebook for months.

So what is Facebook? It’s a simple idea, done well: move the “facebooks” of incoming college undergraduates online, with headshots and interests constituting a basic profile, and then create the tools for nodes on the network to interact and browse each other’s profiles.

It’s also my “latest discovery,” as I joined earlier this spring, egged on by a neighbor. Back when I went to college, we had such a thing, printed on “paper,” bound and distributed to the freshman class (and just as quickly appropriated by upperclassmen frequently interested in more than discovering who else was into rock climbing or Pearl Jam). Facebook was, at its inception, a social network for college students, with access limited to only students in the same institution. Now, Facebook has laid claim to being a “social utility,” bidding to become the platform or framework we use to organize our online lives.

Audacious, perhaps, but not unprecedented. Friendster had the early start in filling that role but never recovered from an inability of its original technical architecture to scale to massive traffic demands or challenges from MySpace and other networks.

To be fair, over the past spring and summer, the social networking phenomenon has continued to explode in popularity and innovation, but Facebook has grown much faster and pulled in the digerati like no other.

Why? There’s no single reason. While the decision to open the formerly closed network to the Internet at large is an obvious place to begin, instead of limiting membership to isolated pools of collegians, other factors are in play. Making APIs available to developers resulted in a tsunami of applications that help to further interconnect nodes within each social network has attracted enormous amounts of energy (and, increasingly) venture capital to the platform.

Choosing to keep a clean, easily navigated interface has mattered as well. While MySpace is still the biggest social network — and by most measurements, the most popular site on the Internet, the contrast between the two services couldn’t be much larger, aesthetically, as Facebook (by comparison) radically limits the visual control a user has over a profile. It doesn’t hurt that all of the young college graduates enter the workforce with profiles, either.

If you need a sense of how bound into the tech community Facebook has become, consider how Silicon Valley reacted to a recent Facebook outage.

There’s plenty of evidence too that spending time on Facebook has also evolved into a significant productivity drain (though some disagree) and security risk. (If you’re wondering which companies lead in embracing Facebook, along with the most risk, just read Elisa’s post). The trouble is that sysadmins with itchy trigger fingers may not be able to quickly shut off the flow of bandwidth by firewalling Facebook. Unlike other more informal networks, many professionals have been using to “friend” their coworkers, clients and collaborators, along with former college roommates and dorm buddies. While LinkedIn has long been the social network of choice for many professionals, Facebook has begun eating into that market. In the online social media world, the gaps between online and offline networks are continuing to close, along with whatever space remained between work and personal lives.

Netizens my age (proud members of the “XY generation” that bridges the gap between Gen X (children of the 80s) and Gen Y (folks who don’t remember life before CDs and email or who said “trust but verify“) and older may find some elements of Facebook surprising, though perhaps not more so than MySpace. Older users are joining, however, and finding a place. While privacy options for profiles exist, unlike MySpace, there’s significant potential for embarrassment and even calamity for college or career prospects for those who aren’t wary about posting photos or blog entries that don’t put them in a good light, to put it mildly. PR professionals and marketers would do well to consider the advice of social media gurus. And, as neighborhood applications crop up, there are also alarming security concerns regarding personal safety and property, given that clever criminals can posit where and when individuals are away.

While much of the value of joining these networks can be found in keeping touch with friends and alumni — and making new ones from within that social network — the amount of information that many people are adding to their profiles has also been identified as a valid phishing risk, with significant potential for social engineering hacks that allow access to corporate networks.

What to do? As is the case with the rest of the Web-based applications that have made their way into enterprise and personal desktops alike (users keep outwitting IT when installing consumer apps, apparently), the key is likely to be adaptive security policies that both recognize the increasingly blurred boundaries between work and personal life while respecting both the bandwidth limitations high usage may inflict upon a network and the need to limit the leak or theft of potentially damaging proprietary or personal data. No one is suggesting that developing, implementing or enforcing such a policy is easy, but the consequences of failing to try may extend well beyond a public relations disaster to the organization or individual who doesn’t consider Facebook to be a risk.

There are also no shortages of critics who view the closed nature of Facebook with some distaste — “yet another profile to populate” is a new form of fatigue in the digital age. Personal data portability may become a online movement. It’s certainly been the inspiration for a business plan or two. The founder of LiveJournal, for instance, has published a mini-manifesto for portable, open social networking, according to Mashable. (It may help that Google appears to be backing him). Other observers have noted that Facebook hasn’t been proven to be a rewarding platform for advertisers yet either, though the model is still evolving, as described in this excellent article from Business.com, the Facebook Economy.

In the meantime, I’ll enjoy watching classmates and friends pop up on Facebook; lest you wonder, you can find me there as well. Be warned: I’m sticking with adding friends, coworkers and neighbors, lest I develop social networking fatigue myself.

WikiScanner: How Googlebombing Virgil led to radical transparency for Wikipedia editing everywhere

Sometime this past summer, future CalTech grad student (and self-styled”disruptive technologist”) Virgil Griffith decided that he wanted to see if he could elevate his personal home page to the top of search results for “Virgil.”

While that dream may or may not come true, there’s no doubt that the “quotes” should now be removed from disruptive technologist, (along with my self-styling). Virgil hasn’t written an epic quite yet but he’s clearly provided a useful tool to journalists and inquisitive netizens alike. Meet WikiScanner.

In two weeks, Griffith created a Web site that matches the IP addresses attached to edits of Wikipedia pages with the IP addresses listed in the publicly accessible whois database for companies and media organizations worldwide.

Using a simple, minimally designed interface consisting of a form, text, dropdowns and hyperlinks, Griffith’s site allows users to first determine what the IP address of an organization is and then plug it into to discover what edits have been made from that IP range.

By providing the means to cross reference who is editing what, Virgil’s code nearly approaches poetry, at least judging by Jimmy Wales, who told the AP that “It is fabulous and I strongly support it.”

It’s not quite fair to say that the effort is all about the Virgil Google bomb, either. According to this Wired article, Griffiths was inspired by the discovery that many Congressional offices were editing their own entries. Wondering what corporations were doing the same thing, he created WikiScanner.

As Griffiths notes wryly in his WikiScanner FAQ, the reaction to the tool’s discoveries has been more or less as expected. The CIA and FBI, Disney, Diebold, Exxon and a rapidly expanding universe of other entitities, large and small, have been editing away. Take a look at Wired’s “list of salacious edits” to see how far the count of “minor public relations disasters” that WikiScanner has enabled — and be aware that any edits that you make to Wikipedia may not be as anonymous as you might think.

Sneakernets, removable storage and hassle-free file transfer methods

One of WhatIs.com’s faithful readers wrote in recently with a suggestion for a much-beloved IT sniglets page (go take a look if you think words like CrackBerry, AlzIMers, IMglish or prairiedogged are a hoot): sneakernet. We love that sort of thing, of course (write to us!) but in this case we already had a definition for sneakernet: a method of transmitting electronic information by personally carrying it
from one place to another on floppy disk or other removable medium. The concepts certainly doesn’t seem many years removed from the days of copying working files onto a 3.5″ floppy disc at the end of the day in the computer room — or even of writing simple algorithms to the cassette tapes attached to the ancient PET computers next to my classroom in the late 80s.

As is so often the case, technology and life comes in cycles. In recent years, the explosion of cheap, removable flash drives (or jump drives, so some folks call them) has allowed mind-bogglingly large sneaker-borne file transfers copied over speedy USB 2.0 ports. iPod owners have long since discovered that those giganormous 80-gigabyte hard drives also make fantastic data warehouses for easy travel and transfer (as long as you don’t forget the cord!) and of course, it’s a cinch for most PC owners to burn a copy of a file to a CD and walk it over to another desk or office. That sort of thing can result in podslurping, of course, as network admins know. Entire operating systems can be carted around as LiveDistros, along with whatever portable applications a user might desire. I won’t even touch, of course, the multitude of flash memory formats that inhabit cameras, smartphones, GPS devices and other electronica, each a potential method of data transfer in “the sneakernet.”

(BTW, hat tip for the cool sneaker image goes to ProZak on Flickr)

So sneakernet is definitely not dead (as noted in this tip from SearchNetworking from 2005). The prompt provided by the reader email did, however, recall to my biological RAM an e-column I read just last week from David Pogue, the witty and frequently funny technology reviewer over at the New York Times. David recently wrote about a trip to California where he managed to forget a folder of 2 GB of digital photos he’d taken of digital SLRs he was reviewing in that week’s paper. With the help of a marvelously patient wife, he managed to get the files transferred over to his laptop from home using a nifty little shareware application called Pando. Pando provides, as David says, “a free, cross-platform, super-simple program designed expressly for idiotproof file transfers, even big ones.”

You can learn more at (you guessed it) Pando.com.

The only snag is that for the service to work, both users have to download and install the client, a step and hitch that David rightly suggests is a potential hindrance, or even impossible for some end users without admin privileges. That being said, Pando worked well for David and is allowing thousands of users to easily backup, transfer, recover and (yes) trade quite large media files. Color me a fan.

Aside from discovering Pando (thanks, David!), the process Pogue worked through is remarkably similar to one that plays out in classrooms and cubicles daily. How to do it? Sneakernet and removable storage is certainly one way, though I hear that the “Interwebs” is an attractive method these days as well. Here’s a crack at a list of ways to make a hypothetical transfer happen. If you have more ideas, please add them in the comments.

For instance, gmail has changed the way that most people think about using email to send attachments, with its remarkably large capacity (convertible to online storage, as I’ve blogged about before, with Gdisk), though I agree with David that 2 gigs is a tag weighty to send this way.

Also like David, I’ve been using FTP for a long time to download and upload files online, though I’ve endured timeouts, unexpected logouts and all manner of file corruptions over the years. I still have fond memories of the early versions of Fetch, including the happy dog icon that accompanied the app. David’s second idea, using an IM-client to transfer files, wasn’t a bad idea at all, though that kind of P2P file sharing isn’t likely to fly on many corporate networks.

As David disco
