Energy and tech

As we attempt to become more conscious of our energy consumption, we do need to consider the energy demands of our technology. I started thinking about this (again) when I encountered a blog post indicating that Google was using its power as consumer to require chip manufacturers to increase the temperature at which computer chips fail. The server farms Google operates require a hefty investment in energy for cooling and greater tolerance for heat would reduce cooling costs. What I know about the energy demands of server farms I have learned from Tom Friedman (Hot, flat and crowded) and technology does use a lot of energy.

You get a sense of the same issue when you enter a school computer lab. My department’s computer lab is located next to my office and we sometimes run the fan on the air conditioner even in the winter. The windows are sealed so using the air conditioner to pump in some sub zero air is the only way to cool the room.

I operate a high end Macintosh in my office. It turns out the Mac has 4 fans evidently necessary to keep the system functioning. I seldom put much strain on this equipment. The most demanding thing I do (programming) is probably the least demanding of my computer. The power of my old 2e would easily keep up if I know how to work using the command line and could connect to my servers.

I wonder if “thin client” technology would save energy – no hard drive, mostly just the energy to power the monitor on the client side. What about the demands on the server side. Perhaps server farms should be located in North Dakota. At least the cost of cooling in winter should be lower.

We could have been contenders

I just finished viewing a short video of Maine’s past Governor Angus King talking about the rationale in support of Maine’s 1:1 initiative. Whatever you think of spending for this particular tech initiative, the Governor’s grasp of educational issues and his arguments for technology were impressive.

Watching this video reactivated this uneasy feeling I have had for some time regarding technology innovation in my own region. At one point, I was convinced that North Dakota was a national leader at the K-12 level. We benefited from and hopefully encouraged developments in our neighbor to the east – Minnesota. The days of MECC represented a heady time and I remember making trips to regional conferences and returning with disks of new educational software. Working in higher education, I was convinced that K-12 folks were far ahead of us.

I do not feel this way anymore and I am not sure whom or what to blame. I think NCLB may have taken K-12 folks out of the game. While those of us in higher education are facing ever more frequent calls for demonstrations of accountability, at least we have yet to identify some standardized tests by which this accountability will be measured.

I also think the good times in ND may be a problem. Yes, I am willing to claim these are relatively very good times. We have a regional advantage that includes agriculture at record prices, oil, and Canadian shoppers. In a state with a small population, the amount of money involved from what many would consider unlikely sources can have a significant impact. Unfortunately, these benefits can be distracting. I was convinced when I regarded North Dakota as innovative that this leadership was a function of our rural setting. Distance education and software were an attempt to compensate for a lack of diversity and the limited offerings that are economically feasible in small schools. Perhaps, the innovation evident in Maine stems from similar challenges. Perhaps now there is less local pressure because the political and public pressure to look forward is less intense.

Big mistake!

Thin client, cloud computing, what’s the difference

The relatively recent focus on “cloud computing” has a vaguely familiar feel to those of us who have been involved with technology for a while. Some of my early ed tech research was conducted with a PDP 11/34 mini computer “serving” a dozen “dumb terminals”. The terminals were basically a keyboard and monitor and everyone connected to the same “remote” computer. Remote in this case meant “in another room”.

A recent NY Times article indicates that “thin client” computing may be on the rebound. The “hook” is often financial assuming that many users can share programs (software) and hardware (server) with the result that the work stations can be less powerful and thus less expensive.

Cloud computing is very similar. For example, many users with low end hardware can connect via the Internet and use Google docs rather than invest in many copies of Microsoft Word.

What is the difference? One difference might be the openness/extensiveness of the network. A thin client architecture serving a company is different than an Internet-based service available to everyone. Perhaps a second difference is how completely “clients” must subject themselves to “the system”. One model of the thin client approach assumes users are connecting with the bare minimum of hardware and software and cannot perform actions that allow independence – e.g., storing local copies of work completed. In contrast, Google Apps allows local storage of resources and through the use of Google Gears independence from the Internet.

While some are concerned that cloud computing is a trap, I am concerned only to the extent the options are few and inexpensive opportunities come at the expense of becoming dependent on one or two providers.

Text To Speech

Cindy has a project underway that involves developing educational resources that ESL students can use from iPods. She has been exploring Text to Speech conversion programs that create audio files.

Here is one example. CK’s Text to Speech takes advantage of the built-in conversion capabilities of the Macintosh. The applescripts convert from selected text in Safari, from a text file, and from the clipboard.

The content read to you here can be viewed on our participatory web site. It is a web page with bullet points, headings and images that may not make the most comprehensible audio presentation, but is fairly typical of an extended web page.

The Macintosh reads text as part of the basic operating system. I have not explored the text to speech capabilities in some time and found the quality to be quite impressive. The connected file allows you to judge for yourself. What is different about this application is the generation of an audio file that can be used in other ways (e.g., used as part of a web page, offloaded to an MP3 player). There are other programs that perform this same function and perhaps do so in a slightly easier way (not requiring multiple scripts/programs). The advantage of the resource we link to is that it is available at no cost.

A little humor – the lures of the phisherperson

A warning appeared in my mail box this morning. Writing a scam must be kind of an art – you obviously cannot offer that much information and yet you must convince the recipient you are attempting to address a very specific problem. I am tempted to write back and ask which of my accounts has generated this concern, but it is probably better to just ignore the request.

Will the free ride on the cloud end soon?

Here is a comment on the present down turn in the economy and the web 2.0 resources we have been promoting for education.

Today, I read comments from several venture capitalists (e.g., Ron Conway) as they offered advise to those they support. The comments expressed concern that while the present financial situation did not originate with online apps and services (like the Internet bubble of a few years ago) tight money would eventually impact tech companies hoping to make their mark with Internet services. The advice was to economize.

Of course, those companies that can find a way to make it through the lean times will likely find they have less competition on the other side. It reminds me of the rise of the Bubba Gump shrimp company – this likely makes no sense unless you are fans of Forest Gump.

My concern is that I invest too much time and perhaps resources I have created in an online (probably free) service that has no way to generate funds. The idea that good services will be bought up by Google, Microsoft, etc. or catch the eye of those with venture capital may not hold in the short term. For example, Yahoo, owner of Flickr, fell below $14 today. Time to back up just in case.

Questions and Some Answers About OLPC

The mission of One Laptop Per Child was to bring very inexpensive laptops to needy children. Perhaps you did the same thing we did and purchased one for ourselves as part of the get one / give one project.

I can’t say that I have used ours much. The keyboard is pretty small for my hands. Originally, I spent some time online, but we switched our router from WEP to WAP and I have been unable to figure out how to configure the new password (it seems you have to convert the password to hex, but the conversion with a Airport Extreme works differently, etc.). I can still get the XO to work at my office.

To me, the project has struggled with direction. The original commitment was to put these computers in third world countries and then it turned out deals were made to offer the machines in some U.S. schools. The machine was to be developed based on open source software and now Microsoft has become involved in the project to include Windows.

This linked interview (Robert Scoble and the COO from OLPC) offers an update.
