The Big Internet Museum: Milestones and Memes

Thebiginternetmuseum-1

If you were given the opportunity to curate a historical museum about the Internet, what would you include? Now's your chance to add to the collection of The Big Internet Museum, a virtual hall exhibiting the milestones and memes of the 43-year history of the World Wide Web. The online museum project was created by Dutch advertising pros Dani Polak, Joep Drummen and Joeri Bakker.

BLOG: Top 10 Social Networking Sites

The collection begins precisely on October 29 1969, the day when former NASA researcher, Robert William Taylor, launched the ARPAnet operational network for the Pentagon's Advanced Research Projects Agency (ARPA). The network is widely recognized as the precursor of what we now know as the Internet.

The exhibit concludes with South Korean megastar Psy, whose 2012 song "Gangnam Syle" became the first video to tally one billion views on YouTube.

As you can imagine, the space between those two bookends spans all that is significant and silly about the network platform that, for better or worse, has redefined our lives. America Online (AOL), Internet Relay Chat (IRC), .GIFs, chat lingo, Hyper Text markup Language (HTML), Flash, Google, Facebook -- even Double Rainbow guy -- get equal billing in this gallery. But that's only a smattering of the collection.

Touch Screen Desks For Next-Gen Schools

StartrekThere are some projects proposed for the future that can make you roll your eyes, and others that make you say, "Can we have this now, please?" The NumberNet desk belongs in the latter category.

Researchers from Durham University have been testing out the multi-touch, multi-user desk as part of a three-year project with over 400 students. The students range from ages eight to ten and use the desk in a group setting. Using the desk in this way allows the students to solve mathematical questions by working together and collaborating on one large platform rather than on multiple sheets of paper.

Much like other multi-touch desks on the market, this one has been designed to recognize multiple touches on its desktop using infrared lights. These screens have been built into existing fabric and furniture in the classroom and are linked to a main smart board controlled by a teacher. Because of this control, a teacher can use the screen as a lecture piece as well. Which means no Power Point or whiteboard and no more peeking over screen-covering tall kids. Solutions and input from other students can be shared to other groups by the teacher through the screens.

So far the project has found that the children who collaborated together showed improvement in mathematical flexibility and fluency, compared to those who used paper-based methods. The lead researcher of the project, Liz Burd says that the whole point of the project is to encourage more active student engagement, "where knowledge is obtained by sharing, problem-solving and creating, rather than by passive listening."

If implemented, this method of learning would encourage participation from all students, and not just one smarty-pants. Only mathematics was testing in this project, but researchers say that it could be applied in other areas of learning as well.

Windows 8: Twice The Interface, Third The Price

Windows 8 split-screen

It's barely been three years since Windows 7 ended Windows Vista's reign of error, but in those three years, computing has been upended by social media, touchscreen devices and app stores. Windows 8 is Microsoft's response to those changes, and much of it may annoy you if you don't understand that.

Windows 8 boots into a radically simplified Start screen (on the left in the composite image above) that displays apps and information as interactive tiles. That concept works well on Microsoft's Windows Phone 7 operating system and even on a laptop with only a keyboard and touchpad, it's still pleasant to navigate.

Windows 8 charms listThe Start screen's new apps -- 9,000-plus of these one-click installs await in Microsoft's Windows Store -- don't look like Windows programs either. Apps like Microsoft's Facebook-, LinkedIn- and Twitter-linked People don't have menus, and their toolbars are invisible unless you right-click on a blank area or swipe down from the top of a touchscreen.

To search or edit an app's settings, you have to tap or swipe in a right-hand corner to reveal an array of icons Microsoft calls "charms." You also need to invoke the charms list to get the time, check a laptop's battery or see the WiFi signal (which in my copy of Win 8, sometimes loses all Internet connectivity even as my desktop stays online).

With a mouse or touchpad, these gestures have you skating the cursor around the screen a lot. Even with a touchscreen, the new interface -- the only one on the cut-down Windows RT edition intended for tablets like Microsoft's Surface -- will take some learning.

That's not bad by itself. Having one app fill the screen, without distracting "chrome" above or below, brings the calming focus of a Kindle e-reader (though you can also "snap" an app into a left- or right-hand column to accompany another). The simplicity of navigation here also reminds me of Microsoft's Media Center and Apple's Front Row, alternate media-playback interfaces built for use without a mouse or keyboard.

But the traditional desktop, at right above, remains a click or a Windows-logo keystroke away. That preserves traditional Windows applications (except in Win 8 RT, which I'll cover in a separate post) and file folders (their windows now group commands in the "ribbon" toolbar Microsoft pioneered in Office 2007).

But there's no Start menu. So if you're on the desktop and want to launch a traditional Windows program, you'll often have to flip back to the Start screen, right-click and click an "All apps" button.

The cluttered Start menu desperately needed renovation years ago, but scrapping it instead of replacing it with a simpler apps menu (perhaps like OS X's Launchpad) seems crazy.

When I installed a preview release of Windows 8 alongside Win 7 on my 2011-vintage ThinkPad this spring, I was impressed by its speed and reduced memory consumption. But when I replaced 7 with 8 Friday morning -- a tedious process that ground along over four hours -- the never-too-fast laptop had become unusably slow.

I resorted to Win 8's new "Refresh" option, which keeps your files and settings, installs a clean copy of Windows and wipes out all third-party software that might have gummed up the system. Windows has needed this for years. And this time it worked, yielding a snappier machine.

So I don't feel bad about the $39.99 this cost me (a third of the $119.99 price of most Win 7 upgrades). But if your job doesn't require knowing new software, your computer lacks a touchscreen and you're content with Windows 7 -- which should describe many readers -- I can't think of why you'd want to pay even that low price right away.

Kids from 1995 Love the Web: Gotta-See Videos

Gotta-see-videosDid you hear? Shark Week is here!

These students from 1995 advocate for Internet usage, but not for better fashion. One out of two ain't bad. The kids tell us why we should be on the Internet. Their predictions are oddly accurate and, if anything, understated.

Their pronouncements involve using the internet as a "telephone, television, shopping center and workplace." As it turns out, they... (we?) weren't wrong.

Animated Characters Printed in 3D

3dmonster


Avid gamers everywhere may soon be able to print action figures of their favorite game characters. Graphic experts and computer scientists from Harvard have created software that can turn any three-dimensional animation (think, Pixar) into a "fully articulated action figure,” according to a press release from the School of Engineering and Applied Sciences.

According to the release, the software returns a virtual character to the real world, which means it has to abide by real world physical constraints. When animating characters from the game “Spore,” surface points are used to determine weight relationships and skeletal positioning. In the animated world, these figures lack joints and other body features that produce real-life movement. The software addressed this problem by identifying the best places on the image for joints, and then adjusted the character’s physical attributes. (i.e. a thin arm equals a smaller joint.)

Skin textures were also optimized for 3D printing. The software analyzed the way light reflected off of the virtual skin and mapped it to a physical form.

Moritz Bacher, author of the study and a grad student in computer science, describes the use of this kind of software for animators, saying, “Right now, perhaps they can print a static scene, just a character in one stance, but they can’t see how it really moves. If you print one of these articulated figures, you can experiment with different stances and movements in a natural way, as with an artist’s mannequin."

Harvard has filed a patent application for the software and plans to commercialize it to either license it to an existing company or creating a start-up, with a focus on customized user-generated toys and enhancing animation.

Card Game for Wannabe Hackers

Control-alt-622
Control-Alt-Hack: $30.00

Think you’re an expert hacker? The “Control-Alt-Hack” card game will put your so-called skills to the test. Developed by professor Yoshi Kohno of the Security and Privacy Research Lab at the University of Washington, this old-school game is geared toward a younger generation with basic knowledge of computer science.

BLOG:Hackers Hit Iranian Oil Facilities

Three to six players can become part of “Hackers Inc.,” a fictional computer security auditing company that instructs players to break into different kinds of systems and expose security flaws. Fifty-six mission cards lay out different hacking challenges. Each player gets a mission and has to decide what tactic he or she will take when the dice is rolled.

Different methods of hacking include hardware hacking, hacking software through coding, accessing networks, social networking hacks or constructing/deconstructing cryptographic ciphers. The different tactics and a points system that goes along with the dice rolls are a little confusing at first, but once you get the hang of it, it makes for a fun and challenging way to test your skills.

The game isn’t necessarily for educational purposes, but Kohno and his team did incorporate real-life hacker issues into it. While it may not be completely educational, U.S.-based educators can request a free copy of the game before it goes on sale in the fall.

Pentagon Develops Reddit for the Military

Milsuite-622
Last to join the party, I've just recently started using Reddit. What I thought was a bunch of disjointed information has turned out to be an interesting source for work and fun. That kind of crowd-sourced information is making its way to the military through a Pentagon-created site called Eureka. The new site will join the group of military-friendly social sites under the label "milSuite," which resemble Facebook, YouTube and Wikipedia and only carry unclassified material.

BLOG: U.S. Military Seeks 'Spidey Sense' Training

The site is projected to go up in mid-July and will only be open to military members to share information, content and ideas to solve problems through a group effort. Users will be able to post stories or tag ideas to have others vote them up or down. The deputy director of the Combined Arms Doctrine Directorate, Jim Benn, says that the formal method of gathering ideas can miss things because, “not only are we working the problem, we’re working the budget and policy issues that surround the problem.” He also mentioned that an external force is sometimes needed to bring issues to the forefront. The hope is that this project can do it efficiently, using its best and brightest source.

Facebook Acquires Face Recognition Site

Face-com-622

Facebook has announced plans to buy the face recognition site Face.com, along with its free mobile app, Klik, which recognizes friends in photos to make tagging on Facebook easier. The acquisition means this feature could be added to Facebook’s mobile app or to the site itself, with possible Instagram integration.

BLOG: Say Cheese! Facebook Camera Is Here

As TechCrunch pointed out yesterday, this is an important move for Facebook and Face.com. The amount of untagged photos on Facebook is huge, especially mobile uploads. These present missed opportunities for interaction. When you are tagged in a photo, it shows up in a friend's news feed without a tag or any notification to friends and family. That’s not always a bad thing (drunken pub crawl photos, anyone?), but tagging in general, whether through photos or events, does make news feeds more relevant to users.

As a side note, this is also a smart way to lessen the time it takes to get to Facebook when autocomplete in Web browsers redirects users to Face.com instead of Facebook.com, but maybe that just happens to me.

Life-Sized Boxing Robots Pack A Punch

Bot2

Last week, while attending Microsoft’s TechEd event in Orlando, I saw a line of guys hanging out at what looked like a boxing ring. I went to check it out and saw two life-sized robots beating the hell out of each other, just like the old Rock-Em Sock-Em game. These are called "BoxingBots" and they were built by Microsoft's  Coding4Fun team, that shows off just-for-fun coding projects on their website.

6a00d8341bf67c53ef016767a91d41970b-800wiThe six-foot tall bots are pneumatic, using pressurized gas for mechanical motion. In this case, the bots use two 2.5-gallon tanks of compressed air at 150 psi. Players control the bots with a Kinect for Windows-enabled PC that reads their movements and maps out their body through a series of dots displayed on screen. Once the player’s dots are in balance and the bots are gassed up, the punches can be thrown. Players deliver punches with a full arm stroke, once the bots are close enough. Leaning forward moves the robot forward on its four omni-directional wheels.

ANALYSIS: Kinect-Powered Amusement Park Will Blow Your Mind

When they throw a punch or lean forward to move the bot, that information is sent to the administrator PC, which can override, reset or pause the game, just in case things get out of hand. Players aim their bot's blows at the center target of the opponent machine's chest. The target is powered by Phidgets LED controller board and when hit enough times the bot is “knocked out.” (Phidgets-based systems are popular with robot lovers because they allow robots to be controlled by a simple PC and are low cost.)
