Gordon And Mike's ICT Podcast
Perspectives on Technology and Education from Gordon F. Snyder, Jr. & Mike Qaissaunee

We have spent a lot of time the last few months discussing the excitement and benefits of Web 2.0 technologies but have not spent much time discussing the inherent vulnerabilities of these technologies. Earlier this month the application security experts at SPI Dynamics Inc. put their collective heads together and took a look at the threat landscape for 2007. Specifically, the researchers identified seven threats that they expect to be prevalent during 2007. In this podcast we take a look at this SPI white paper and discuss these threats.

Intro
In our previous discussion regarding gaming we learned about Massively Multiplayer Online Role Playing Games or MMORPGs. Among the most popular was World of Warcraft. This week we consider The Webware Wars. Among the factors that have led to the proliferation of webware are: increased adoption of high-speed internet, greater bandwidth, cheap storage and a new dynamic and interactive web architecture enable by a collection of technologies referred to as Web 2.0 and AJAX. Everybody's getting into the act, including big players like Microsoft and Google, and little fish like Zoho and Thinkfree.

Mike, let's start out with what we have been using the longest - What are some of the New Features in Google Docs and Spreadsheets?

As with any Google product, new features are quietly added with little notice or fanfare. Since we last talked about Google docs and Spreadsheets (GDS), there have been a number of additions and improvements - mostly on the spreadsheets side of the house. The first addition is actually within Gmail - Google's popular web-based email. In the past, when a Gmail user received an email attachment (either word or excel) the only option was to open the attachment as an an html document-viewing only, or download and open the attachment. Now when a users receives an excel document, the have the option of opening that spreadsheet directly in GDS - presumably, a similar functionality will eventually be available for word documents.

Can you describe GoogleLookup?

This a new feature in the spreadsheets portion of the GDS that takes advantage of the online nature of GDS. In fact, it's a formula in the spreadsheet that attempts to answer a question by using information from the web. The syntax is fairly straightforward:
=GoogleLookup("entity", "attribute") [the double quotes are required!]
Some examples include:
  • looking up the population of New York City [=GoogleLookup("New York City", "population")] or
  • when Google was founded [=googlelookup("google", "founded")]
  • =GoogleLookup("Springfield, MA", "population") gives us 152,082 
  • =GoogleLookup("NJ", "population") gives us 8,414,350
If you mouse over the cell, you'll see links to the source pages. Don't expect to change the world with this function, but have fun with it.

What are some of the entity types you can look up?

Here are some of the types of entities you can access using GoogleLookup, and a few popular attribute names (some entities won't have all these attributes, and some will have more, so experiment):

  • Countries and Territories (like "Burkina Faso"): population, capital, largest city, gdp
  • U.S. States (like "Tennessee"): area, governor, nickname, flower
  • Rivers (like "Amazon River"): origin, length
  • Cities and Towns (like "Chicago"): state, mayor, elevation
  • Musicians (like "John Lennon"): date of birth, place of birth, nationality
  • Actors (like "Audrey Hepburn"): date of birth, place of birth, nationality
  • Politicians (like "Anwar Al-Sadat"): date of birth, place of birth, nationality
  • U.S. Presidents (like "Zachary Taylor"): date of birth, place of birth, political party
  • Baseball Players (like "Wade Boggs"): games, at bats, earned run average, position
  • Chemical Elements (like "Helium"): atomic number, discovered by, atomic weight
  • Chemical Compounds (like "Isopropyl Alcohol"): chemical formula, melting point, boiling point, density
  • Stars (like "Betelgeuse"): constellation, distance, mass, temperature
  • Planets (like "Saturn"): number of moons, length of day, distance from sun, atmosphere
  • Dinosaurs (like "Velociraptor"): height, weight, when it lived
  • Ships (like "USS Chesapeake"): length, displacement, complement, commissioned
  • Companies (like "Hewlett-Packard"): employees, ceo, ticker
What about GoogleFinance?
While GoogleLookup provides access to a wide variety of data, another new feature, GoogleFinance provides just financial data pulled from Google Finance. Using a similar syntax, you can look up the price of Google stock [=GoogleFinance("GOOG")] or the 52-week high of Apple [=GoogleFinance("AAPL", "HIGH52")]. And since this type of data changes fairly frequently, they are updated in your spreadsheet automatically.

How has Publishing Improved?
Google has also improved web-based publishing of spreadsheets. You can publish your entire spreadsheet (or just one sheet of it) so that other people can view it as HTML, or PDF - without having to sign in to a Google Account. The HTML even updates is the original spreadsheet changes.

Last week in Houston you demo'ed something called Thinkfree - can you tell us about that?
Thinkfree
http://www.thinkfree.com/common/main.tfo

A new addition to the webware wars is Thinkfree and their online office suite. Like GDS, Thinkfree provides online access to Word and Excel documents - what differentiates it is the addition of powerpoint and the ability to create charts in calc - their version of Excel. Thinkfree provides 1 Gig of space for their Thinkfree Write, Calc and Show suite. The collaboration and revisioning features are very similar to GDS. I would rate the interface a little cleaner and more user-friendly - Thinkfree refers to your online documents as your webtop, as opposed to your desktop. Like GDS, the architecture is AJAX-based, but Thinkfree uses JAVA as well. Another interesting feature that the Thinkfree suite provides is a doc exchange - an online repository that users can publish their documents to and share with one another - in fact this feature allows for a variety of creative commons licensing options. Another neat option is the Bulletin Board - sort of a guest book, where you can view all of your published and blogged files, collaborate with other Thinkfree users and get feedback from people all over the world.

Another unique thing about Thinkfree's Online office suite is that it's just one of a number of products that they have launched. In addition to the free online version, there are commercial versions available including a server version, a desktop version and a portable version. The desktop and server versions are cross-platform, running on Windows, MAC and Linux and are reasonably priced ($50 desktop, server pricing starts at $30 per user per year). The portable addition runs on a U3 drive - similar to a USB drive, but with the ability to run applications - see http://www.u3.com/default.aspx for more info on U3 technology. Finally, there's a version of portable show (powerpoint) for the iPod.

Are there any other applications we should take a look at?
Solodox
http://www.solodox.com
Not nearly as far along in development as either GDS or Thinkfree is Solodox. In fact, on their website, the product is listed as an alpha - in the nomenclature of software development and testing, alpha-testing is internal testing that occurs before the software is made available to the public for beta-testing. So why bother discussing a product that's not ready for prime time? Well what's unique about Solodox is that in addition to providing a web-based word processor with features similar to other such products (creating, editing and sharing documents) Solodox And Solodox supports English, Japanese and Chinese.

Where is Microsoft going with this webware technology?
In the December 4 issue of Business Week Seattle Bureau Chief Jay Greene interviewed Kevin Johnson, co-president of Microsoft's platform and services division, which makes Windows, and Jeff Raikes, president of Microsoft's business division, which is responsible for Office. Here's a couple of quotes from this interview:

In the Web 2.0 world where everything seems to be moving online, it almost seems anachronistic to be talking about packaged software.
RAIKES:
The new world of computing is the combination of software and services, and Microsoft is very, very focused on that services opportunity. I think the point that some of the competition misses is they think of it as an either/or situation when in reality it's an "and" situation--it's software and services, and you use the combination to do the best job for the customer.

But doesn't the growing importance of the Web and all sorts of devices require Microsoft to take a different approach?
RAIKES:
You might think the core of our business is the PC. That's the misconception. The core of our business is software. And the software can be applied to the PC, the software can be applied to the server. When K.J. [Johnson] was joining the company [14 years ago], servers were kind of just getting started for us. Now we're big in game consoles. Did we want to get into Xbox because we wanted to be a hardware company? No, Xbox is a vehicle that allows us to deliver software. Zune is about software. So we are about software, and if you stick to that understanding of our company, then it's a lot easier to see how we transform.

The pricing has me a bit concerned: http://office.microsoft.com/en-us/products/FX101754511033.aspx

Intro
According to wikipedia.com: Social media describes the online tools and platforms that people use to share opinions, insights, experiences, and perspectives with each other. Social media can take many different forms, including text, images, audio, and video. Popular social mediums include blogs, message boards, podcasts, wikis, and vlogs.

In this session we'll take a look at a few of the common social media applications including mySpace, Facebook and Flickr. We'll also look at some applications that are designed specifically for academic use.

Gordon, can you tell us a little more about what these social media tools?
�What we want to express with the term social media is the fact that in media design we are aware of the existence of others and the collaborations we see happening through the so-called social software. Concrete examples of social media are online communities, social networking places, social sharing tools (flickr),.... �

Flat World Strategies: Online Games People Play

Overview: According to wikipedia.com: MMORPGs are online Role Playing Games (RPG's) in which a large number of players interact with one another in a virtual world. As in all RPGs, players assume the role of a fictional character (most commonly in a fantasy setting) and take control over many of that character's actions. MMORPGs are distinguished from single-player or small multi-player RPGs by the number of players, and by the game's persistent world, usually hosted by the game's publisher, which continues to exist and evolve while the player is away from the game.

Today business and industry (including Intel and IBM) along with academic institutions (including Harvard and the University of Washington) are developing MMORPGs that provide education and training. In this session we'll take a look at some of the common games and discuss how they could potentially be used in our classrooms.

Social Networking
A social network is a social structure made of nodes which are generally individuals or organizations. It indicates the ways in which they are connected through various social familiarities ranging from casual acquaintance to close familial bonds. The term was first coined in 1954 by J. A. Barnes (in: Class and Committees in a Norwegian Island Parish, "Human Relations"). The maximum size of social networks tends to be around 150 people and the average size around 124 (Hill and Dunbar, 2002).

Social networking also refers to a category of Internet applications to help connect friends, business partners, or other individuals together using a variety of tools. These applications, known as online social networks are becoming increasingly popular[1]. Source: http://en.wikipedia.org/wiki/Social_networking

Have you ever been working collaboratively on a document, either with one other person or multiple people? Have you been frustrated looking through your computer or your email for the most recent version or even an older version that that has something you've since deleted? Worse yet, have you ever been looking for that file wondering if the most recent version is on my work computer, my laptop, my home computer, my email or any number of usb drives I have laying around - or even worse yet on someone else's computer. What about collaboration - sending a file around by email, everyone adds their comments and you have to try to put it all together - what a hassle. And who can stand to read documents with track changes turned on. Well there's a new class of applications called webware coming to the rescue!

Gordon: Mike - what is webware?

Webware is an online software application that trys to replicate the richness and responsiveness of a traditional desktop application. What's really made this even remotely possible is the widespread adoption of high-speed or broadband internet and a new architecture for the Web (Web 2.0 and AJAX - we'll talk about these more some other time). Google Docs & Spreadsheets is an example of webware - an online analogue of the ubiquitous Microsoft Office.

Gordon: I know we've been using Google Docs and Spreadsheets - can you give our audience an overview of how these applications function?

Google Docs & Spreadsheets is a fairly full-featured online word processor and spreadsheet editor that enables you, your colleagues and your students to create, store and share documents and spreadsheets. It's this sharing - the collaboration - that's really exciting! Sharing enables you to decide who can access and edit documents, and even better, all changes are kept in a document revisions history. You can create documents from scratch or upload existing documents and spreadsheets. Other than a web browser and a network connection, there's no software required, and all your documents are stored safely online and accessible from any network-connected computer. Some of the neat features include being able to save documents to Word, spreadsheets to Excel and either (documents or spreadsheets) to HTML or PDF. The Spreadsheets even have a panel that allows collaborators to have a live chat regarding the spreadsheet. A particularly useful feature - AUTOSAVE - means you never have to remember to save your work!

How are people using it? Teachers are publishing announcements about upcoming assignments and monitoring student progress via the revision history. In the revision history, you can see clearly who contributed to what assignment and when; if a student says he or she worked on a given project for five hours, it will be documented (no more "dog ate my homework" excuses). Additionally, faculty are using GDS to keep track of grades, attendance, student projects and assignments. Students are using GDS to stay organized and work more effectively. Google Docs & Spreadsheets helps promote group work and editing skills, and encourages multiple revisions and peer editing. Students can go online to collaborate with other students, teachers, parents, relatives and tutors, and enter updates anytime from anywhere. And through their revisions history, kids can check how they've revised a document and who has helped. Not to be outdone, Google spreadsheets allows students to track their grades, assignments, semester goals, baseball statistics, car expenses, or anything else that interests them.  

Gordon: Can you give us some more examples of how these can be used?

Consider the example of a high school English and journalism teacher who uses Google Docs & Spreadsheets to help facilitate students' work and has found significant improvement in their writing.  Among the reasons she gives, GDS:

               -     facilitates peer editing and revising,

               -     allows for multiple versions of an assignment,

               -     allows her to see who students collaborated with and when,

               -     prevents students from losing documents either by failing to save or having crashed hard drives, and

               -     provides 24/7 access to their documents from anywhere in the world.

Adds the teacher - "It has changed the way I teach writing... for the better!!"

Here are some interesting uses other people have found for this tool: http://www.google.com/google-d-s/tour5.html

Imagine the way you could use GDS in your work - collaborating with colleagues to develop curriculum, a budget or even complete committee work - the possibilities are endless - take it for a spin and let me know what you think at mqaissaunee@brookdalecc.edu

Mike: Gordon, there's been 3 new products released in the last week - the Zune, the Wii and the PS3. Can you give us a quick update?

Zune

Microsoft's Zune digital media player came out a week ago and has had mixed reviews.

Positives:

Looks including color choices of white, gray or brown

Connectivity: 802.11 b/g with range up to 30 feet

 Zune's wireless song-sharing functions (many are calling this aa killer app), which allow users to digitally "loan" songs to other Zunes. Those loaned songs disappear from the devices after three plays. The song-swapping capability has been dubbed "squirting." Microsoft is working on other uses for squirting, and has called the song exchange a good first step in using the technology. Although the wireless sharing does not allow users to expand their music libraries permanently, it could give Zune owners a way to try out music and see if they like certain songs enough to buy them.

Negatives:

Weight, which is heavy for a digital media player, coming in at 5.6 ounces.

Critical mass is not there yet - yes you can do file sharing with other Zune users but how many people do you know that have bought one?Time will tell!

Mike: How about the Sony PS3 and the Nintendo Wii?

Looking at www.gametalk.com and the Next Generation Console Debate forum where people discuss  Xbox 360 vs Wii vs PS3 you get the usual fans - and most of these people are pretty dedicated to their favorite platform. I (or correction - my kids) got a Wii and I get it play it sometimes. When I do get to play it - it is incredible. The controller - what I like to refer to as the user interface - is incredible. It's wireless and what I would probably call like a wand or a television remote control. You swing the wireless controller like a baseball bat or golf club or tennis racket. You can even simulate the throwing of a bowling ball. You can also attach the optional nunchuck controller and play two handed games like boxing. On the gametalk website there are lots of people complaining about sore arms - I know you sent me a tongue in cheek link written at Scientific American titled: Could the Nintendo Wii Reverse the Childhood Obesity Trend? Based on my own personal experience I think it could. Yesterday I threw 120 pitches in 7 innings and ended up having to ice my arm!:) Seriously - it can and does provide an excellent workout. I'm waiting for Nintendo to come out with Velcro sensors you wrap around your ankles. This would allow both the feel and arms to move - think of the potential -  DDR for all 4 limbs!!

The Nintendo is about half the price of the high end PS3. I have not used a PS3 so can't provide much comment on usability. The control has some limited motion capabilities but not like the Wii. The graphics are supposed to be incredible.

Mike: What about the Microsoft Xbox 360?

The 360 is sorta old news believe it or not. It launched in March of 2005 so it's tough to compare to the new products from Nintendo and Sony.

We'll have to put together a separate podcast comparing these products once my arm gets better!!!

Intro Mike:

On November 6, 2006, BroadLogic Network Technologies, a San Jose chip manufacturer, announced The World's First Massively Parallel, Multi-Channel Video Processor, a terapixel-speed video processing chip that will allow cable providers to recover bandwidth that can then be used to deliver more high definition channels, video on demand and high bandwidth data services without major network upgrades.

 

Mike: Gordon, before we discuss the Boradlogic product, can you give us an idea of how current cable delivery systems work?

 

Traditional cable delivery systems work by allocating 6MHz of analog bandwidth for each channel. Most cable providers offer approximately 80 channels that consume (6 MHz/channel x 80 channels) 480 MHz of bandwidth. Typical cable networks provide only 750 MHz of bandwidth and with 480 MHz used for video, there is not much left for other services.

 

Let's think about this a little bit more - one channel consumes 6 MHz of bandwidth but it takes 480 MHz of bandwidth to deliver that single channel to your TV while "wasting" (480 MHz - 6 Mhz) 474 MHz of bandwidth. Not very efficient even if you have a few TV's going in your house watching different channels at the same time.  In summary and according to an article at Light Reading and linked in the show notes:

 

Each analog channel consumes 6 MHz of capacity (or roughly 1/125th of the total capacity of an upgraded cable plant). Re-claiming that channel slot frees up enough capacity to launch 2 more channels in HDTV (each of which consumes about 2.4 MHz), or ten more digital Standard Definition (SD) channels (each of which consumes about 0.6 MHz), another ten QAMs, each capable of delivering an additional VOD stream, or more broadband [Internet] capacity.

 

Many of the hundreds of digital broadcast TV channels a cable operator delivers are not being watched at any given time. It is a network inefficiency that can be remedied by simply switching off those channels that are not being watched. By reclaiming much of this analog spectrum, splitting fiber nodes, and employing switched broadcast video (SBV) techniques, there is lots of room for cable to expand service offerings, including HDTV and VOD.

 

SBV has attracted major interest to this point and involves the delivery of all 80 or so channels in digital format � it works but requires every attached TV in the house to be connected through a set-top box with each box having its own remote controller - we have 6 connected TVs in my home now so 6 boxes plus 6 more controllers - expensive and we have enough time keeping track of a single remote.

 

Light Reading says Comcast Corp. has an aggressive plan to cut the average number of analog channels it carries in half over the next five years, from 70 to 35. That means moving some three dozen basic cable networks from analog to digital-only carriage.

This is where things get interesting:

Until digital penetration reaches 100% being left off the analog tier means reduced distribution. And that means lower affiliate fees, and lower advertising revenue.

It's gonna be slow because subscribers will not want to pay for the extra boxes, will not have room for them on their shelves, etc.

This means the programmers will fight this tooth and nail. Ironically, it is SBV that may well help prove their case is built on a house of cards. Cable TV programming networks sell themselves to advertisers based on their total distribution footprint - say 40, 60, or 80 million homes. The metric is bogus, as only a small fraction of homes are viewing it. With SBV, MSOs will have all the statistical details on who is watching, and eventually, so will advertisers.

Mike: So last week along comes Broadlogic, what does this product do?

 

According to Broadlogic website:

 

The BL80000 TeraPIX chip is capable of decoding dozens of digital video streams and generating a full analog and digital service tier, including an 80-plus analog channel lineup, that any number of cable-ready devices (TVs, DVRs, PCs with tuner cards, etc.) can view, plus up to 160SD or 50HD programs.

 

The TeraPIX processor powers a new type of Residential Gateway, installed outside or just inside a residence, which allows the network to be all-digital, while subscribers continue to receive the cable-ready analog video, digital video, high speed data and voice services they crave. Conventional set-top boxes output one channel at a time and thus feed only one TV. Cable MSOs can use this technology to take their networks all digital, thus tripling their digital capacity at a time when rising content and competitive requirements demand it.

 

Mike: It sounds like the Broadlogic chip may be a much more cost effective solution - can you give more detail?

 

More according to Broadlogic website:

 

The BroadLogic TeraPIX video processor works by decoding bandwidth-conserving digital video signals delivered by a cable operator, and generating 80-plus high-quality channels of television. Cable operators get their extra bandwidth, and consumers get the channel lineups they're used to without having to get more set-tops, run more coax, or lose more remotes.

 

The TeraPIX processor enables solutions that support virtually all existing analog and digital consumer devices. For example, if a subscriber has a DVR set-top from their cable operator, the digital signals are passed through TeraPIX to the DVR.

The price of an individual chip is around $300 when purchased in bulk (1000 or greater numbers)  and cable companies are saying this could be a cost effective way to increase network bandwidth.

The technology is moving at such an incredible pace and it is easy to see more bandwidth and more applications and, from an academic perspective, the ability to provide more and more quality IP delivered content to our students at a distance. Very exciting stuff and - what's next??

Mike: Let's change the subject a bit - I know you took a train ride last week and performed an interesting "experiment". Can you fill us in with some details?

 

On Tuesday I had an excellent visit with the Borough of Manhattan Community College Video Arts and Technology Program (http://www.bmcc.cuny.edu/speech/VAT/VAT.html ) faculty and administrators. BMCC has an NSF project grant titled "Creatiing Career Pathways for Women and Minorities in Digital Video Technology" , an exciting project with an HDTV focus. We're looking forward to lots of good results from the VAT group at BMCC.

Instead of driving I took the AMTRAK train down to New York City from Springfield, MA. I had my notebook computer with me and on the way home, as I was doing some work, I decided to let NetStumbler ( http://netstumbler.com/ ) run in the background. NetStumbler is a Windows application that allows you to detect 802.11b, 802.11a and 802.11g Wireless Local Area Network Access Points (WLAN AP's). In addition to Netstumbler, there is MacStumbler for Macintosh computers, and Kismet for machines running Linux.

Many people use Netstumbler for wardriving that involves driving a car around with a wireless enabled laptop or PDA and logging wireless Wi-Fi networks. According to the Netstumbler website wardriving was first started in the San Francisco area by the Bay Area Wireless Users Group (BAWUG) and is similar to using a scanner for radio. Many wardrivers will use GPS devices to find the exact location of the network found and log it on a website. In fact, if you have a GPS device attached to your computer Netstumbler will automatically log the latitude and longitude settings for future reference. There are several active databases on the web that maintain lists of open hotspots - one of them is maintained and accessed via the Netstumbler site.

In the train I started up Netstumbler on my PC at the New Rochelle, NY stop and just let it run until I got to Springfield, MA with some interesting results. Netstumbler logs, among other things, the access point MAC address, SSID and whether or not the AP is running any kind of encryption. An un-encryped access point is one that is wide open for access. Between New Rochelle and Springfield I logged 1441 access points, many unencryped and wide open for public access. SSIDs were sometimes very descriptive and I found open access points from at least one large insurance company, one law firm and the 36th floor conference room of an unknown company. I also got a kick out of some of the creative SSID names people are using.

Hundreds of the access points still had the Vendor SSID with linksys, NETGEAR and default [note: SSID default is commonly used by no-name routers sold by the big box retailers] popping up on my screen as we rocked along the tracks at 60 mph. Hundreds were setup for open access - I could not actually log in to any because we were moving to fast but I'm convinced I could walk the tracks from New Rochelle to Springfield and maintain free wireless access by piggy-backing on these networks.

I don't want to get into a debate on what's legal and what is not - my concern is seeing so many open access points with many likely connected directly into corporate networks. I thought we had this security problem licked but it appears many are still buying these things and just plugging them in.

Anyone want to carry a load of batteries?

Flat Word Strategies: New Technologies Create Interactive Learning

 

Introduction

In "The World is Flat," Thomas Friedman makes the case that a number of forces have converged to flatten and restructure the global competitive landscape, and that this process is continuing and accelerating.  This flattening has empowered individuals to compete and collaborate on a global scale like never before.  As educators, we must understand the implications for us, our students and our institutions and more globally on education and learning.  Key flatteners that are already impacting education include the Internet, open source software, search, wireless/mobility, VoIP, digitalization, personalization and virtualization. One of the key observations of this less predictable, less hierarchical flattened world is that knowledge is widely distributed and rapidly changing leaving traditional course-based learning increasingly unable to meet the needs of students.  Bridging this divide requires new paradigms in education that incorporate "flat' world strategies such as informal learner-driven knowledge transfer and new technologies and forms of learning.

Question from Mike: Gordon, can you give us a little background on some of the new tools being used?

In the 1990's many of us first started to use the Internet to deliver and supplement content for our courses. We developed relatively static web pages that included text and pictures in similar format to traditional textbooks. Today with the combination of high bandwidth access and new development tools, fresh web content looks and feels much different. With "Web 2.0" tools and delivery methods, instructors are discovering new ways to develop and deliver content to and engage their students. Among the new tools finding their way into business and into the hands of our students are:

  • Search,
  • Instant Messaging,
  • Blogging/Podcasting,
  • Wikis,
  • RSS/Subscription, and
  • Wireless/Mobility.

While many faculty are well-versed at using websites, email, and course management systems to interact and engage with their students, most have been slow to adopt some of these "new" technologies into and outside of their classroom.

These new tools are part of the dynamic, interactive new Internet many are calling Web 2.0. According to techtarget.com, the term Web 2.0 was first used by O'Reilly Media and MediaLive International in 2004 during a next generation web conference. Web 2.0 based technological advances have continued over the last two years and new applications are coming out daily that allow faculty and their students to experience new ways of interacting and learning. Much of this new technology is built around two fundamental technologies, AJAX and RSS.

Question from Gordon: AJAX � that�s soap, right Mike?

Jesse James Garrett of Adaptive Path (www.adaptivepath.com) is responsible for coining the acronym AJAX in a February 2005 article. In the article, Garrett describes AJAX or Asynchronous JavaScript and XML, as a new approach to web applications. In terms of user interaction, what makes AJAX stand out is that it allows developers to create web applications that start to approach the richness and responsiveness of desktop applications. AJAX is not a technology, nor is it code or an application that can be downloaded. Instead, it is a collection of technologies that have all matured and when combined together provide for a new paradigm for the architecture of web applications.  More precisely, AJAX includes XHTML and CSS; DOM or the Document Object Model; XML and XSLT; XMLHttpRequest; and JavaScript.

 

Technologies

Role

XHTML + CSS

Standards-based presentation

Document Object Model (DOM)

Dynamic display and interaction

XML + XSLT

data exchange and manipulation

XMLHttpRequest

Asynchronous data retrieval

JavaScript

Binds everything together

 

To understand how AJAX works, we first have to understand the classic or traditional client-server web application model.  In this model, user actions (typically through a web browser interface) trigger an HTTP request back to the web server, which processes the request (retrieving data, performing calculations, etc) and responds to the client (user) with an HTML page.  While this model has been extremely successful at building out the Internet, it breaks down when developers try to replicate the user experience of desktop applications.  Thatâ��s where AJAX comes in.  AJAX represents a fundamental shift in what's possible on the Web.  To provide this functionality, we introduce an AJAX engine as an intermediary into the traditional client-server model. Simply put, instead of loading a web page at the start of the session, the browser loads the AJAX engine on the client side of the relationship.  This engine is JavaScript code that coexists with the browser, usually in a hidden frame, and is responsible for rendering the web interface and communicating with the web server on the user's behalf.  Practically speaking, what this does is ensures that the user is never looking at an empty browser window waiting for the server to respond and the page to refresh.  With first generation web technology, user actions would generate an HTTP request; with AJAX these requests are JavaScript calls to the AJAX engine.  Many user actions don't require communication with the server and can be handled by the engine.  If the server is needed, the engine makes the request asynchronously using XML, with no interruption of the user-application interaction.

Question from Mike: Gordon could you tell us a little bit about RSS?

RSS (RDF Site Summary and also referred to as Really Simple Syndication) is a technology used to push content out to subscribers using an aggregator application like My.Yahoo or Google Reader. In addition web browsers like FireFox and Internet Explorer 7.0, along with Mac OS X and Microsoft's upcoming Vista operating system, have built in aggregator functionality. These applications allow the user to subscribe to different feeds and have content pushed out to the aggregator. Here's an example of how you can use this technology � if you have a free Yahoo account, you can configure your account to aggregate, or collect, different types of content. Once setup, you can go to any computer with a browser and an Internet connection, go to My.Yahoo.com, log in with your username and password and have your custom page come up with all of your subscribed feeds listed. Your feeds are selected by you and you can add and remove as you see fit. Here are some the feeds we like and subscribe to: Gizmodo for breaking gadget news, Broadband Reports for news on delivery technology and Information Week for breaking IT news. Let's look at how it works � let's say Information Week publishes an article on a IT workforce needs � if you are logged in to your aggregator and subscribed to the Information Week feed, you see the title, a brief summary of the article and how long ago it was published (minutes, hours, days, weeks, etc) on your aggregator page. If the article looks interesting you can click the link and then read the entire article. This technology has allowed many to cut back considerably on hard copy technology journal reading and email subscriptions � most common journals and periodicals are now publishing content with RSS feeds, allowing readers to subscribe and rapidly scan and review content.

RSS developers create an XML file that describes content as it is posted on websites. The blog at nctt.org/blog is a good example if you want to take a look at an XML file. The blog is written using a word processor and then the content is typically copied and pasted into a blog editor with the XML file automatically updated with the latest content. If you are a subscriber to nctt.org/blog your aggregator checks the NCTT blog site periodically for updates and, if it finds one, it lists the content on the aggregator screen. You can see a brief summary on the aggregator and, if you wish to read further, you can click the link and read the entire blog.

Your current students are using this technology on, in some cases, a minute by minute basis. Let's take a look at how it can be used. Let's say you wake up one morning not feeling well and have to cancel your classes. When and how do your students find out you are out sick? Maybe you send out an email which requires students check their campus email account or (worst case) you call in and a note goes on the door or board. In both cases many, if not all, of your students will show up for class and be disappointed to find out you will not be there. Using a simple RSS feed, you could give your students the option of subscribing and actually push the message out to their cell phone or other connected device. Students get the message and do not end up showing up for a class that has been cancelled.

Question from Gordon: Mike, What are some of the popular apps out there now that people are using?

The �killer app� or application that demonstrated the potential and viability of AJAX is Google�s gmail service. The use of AJAX has since exploded. Examples include the aggregators we mentioned earlier, which all leverage AJAX technology to provide for a more pleasing user experience, as well as a whole class of �webware� � web-based applications that attempt to replicate desktop applications, including Writely, ZohoWriter, ZohoShow, Google Spreadsheets, and DabbleDB. With these applications, you and your students have access to a virtual office suite, allowing students to interact and collaborate online. This new class of tools and technologies provide faculty with an opportunity to engage their students inside and outside of the classroom.

Question: Gordon: Where can people find the content of this article?

You can find the content of this podcast in the Oct/Nov 2006 edition of Community College Journal, at nctt.org/blog and at nctt.org/podcast.  In addition you will find a maintained list of several interesting links that further demonstrate these technologies. You can reach the authors at gsnyder@stcc.edu and mqaissaunee@brookdale.edu and at their National Science Foundation center and project websites at www.nctt.org and www.maitt.org

Researched and written by: Michael Qaissaunee
In Death by Powerpoint, we talked about becoming a better presenter, but we (myself included) take for granted that the copious notes students take in class capture the key aspects of our great lectures, are well organized, and will provide what students need to retain for tests and for further courses. Have you ever looked at your students' notes? As an exercise, try collecting and reviewing notes from a cross-section of your classes. Most faculty won't be surprised to learn that good note-taking is a lost art. This got me to thinking ... Where do our students and our kids learn to take notes? What I've concluded is that we don't, at any level, do any formal education on note-taking - it's all ad-hoc; most teachers are rightly focused on the content. But what's really troubling here, is that good note-taking is a critical part of learning and clearly we don't do enough to teach it and to reinforce with students the importance of good note-taking.

What I'd like to introduce to you today is the Cornell Note-taking method. Developed by Cornell's Walter Pauk to help Cornell University students better organize their notes, this system is just one of many different strategies designed to help students take more effective notes. No one method is better than another, the goal is to find a method that works for you. I encourage you to share this method with your students and encourage them to give the method a chance. At the very least, it will get them and you thinking about how they take notes.


The Cornell Note-Taking System

To use this system, separate your page into 3 separate sections (nice illustration here), as follows:

  1. The Notes column (6-6.5 inches wide on right) is the largest and primary section. This is where the notes go, whether they're lecture or textbook notes.  Stress using bulleted lists for easy skimming, as well as economy of language - abbreviations (see resources below), short sentences and fragments and eliminating all unnecessary words. 
  2. The Cues column (2-2.5 inches wide on left) is used to highlight main ideas, clarify meanings, give examples, draw diagrams, or link ideas and examples. If done well, this area is where you do the bulk of your studying from.
  3. The Summary area (1-2 inches high on bottom) is used to reinforce concepts and provide an overview area where you write a sentence or two to summarize the notes on the page. This section is great for skimming your notes and locating information. 

Now for the technology
You didn't think I'd do a blog without including some sort of technology did you? I really don't have the time nor the inclination to sit with pencil, paper and a ruler to layout the Cornell method. So instead, here are a couple useful links:

  • The Cornell Method PDF Generator is a web-based form that creates printable PDF's in the Cornell style with either unlined, ruled, or graphed notes sections.
  • Cornell Word Templates provides instructions for creating your own Microsoft Word Cornell template, as well as down-loadable template that can be customized to suit your needs.

Writely and other Google products like Google Spreadsheets, Google Calendar, Google Talk and Gmail have become a pretty formidable combination. The only disadvantage at this time is you have to be online to use. Next year, with new browser versions coming out, things will change significantly.

Jajah, started by Roman Scharf and Daniel Mattes in 2004, is offering an interesting service that may challenge Skype and other similar products. Jajah provides a paid service that allows calls to be routed landline/cell to landline/cell in many parts of the world without long distance fees. Here’s how it works: Let’s say I’m a Jajah customer and I want to call my brother who is living in London. I log into my Jajah account at jajah.com, enter my brother’s landline or cell number and my landline or cell number. Jajah makes the connection and rings my phone and then my brothers phone over connections that are local to each of us.
