The IPod Syndrome

I just came across an article about the cottage industry which has sprung up to repair broken IPods. The IPod is a marvel of engineering, but apparently is very fragile. But, did you ever notice that modern consumer products are a perfect example of the inverse relationship between technology and triviality?

The Apple IPod may be a marvel of engineering, but what it does is to serve up a completely canned and trivial application - playing recorded music - especially when you consider the complete banality of most of the music played on the device. The device makes it easy for users to "consume music", but at the expense of creativity. What you see is what you get - or should I say what you paid for.

At least in the old days of surfing radio stations for "tunes", even if by accident you were at least marginally exposed to different music as you paused to listen for a minute as you swept past different stations. And every so often you found something that absolutely intrigued you and lead you on the path of new discovery.

Not that I am arguing against IPods, I think they are neat. But if you take the time to examine side by side the any kind of product, one designed for purely consumer use, and the other for serious/professional use, in most cases the professional version has a lot less automatic controls, and requires a lot more manual input. The professional version requires the serious user to pre-visualize the end result and allows him or her to put more of their personal touch into the work to achieve the visualization. There-in lies creativity.

Now everything is getting more and more packaged. From vacations to meals to IPods and music, our society seems to be bent on creating a comfortable cocoon around us, and a kind of "stay in-the-box" world mentality. We are lulled into a fixed way of thinking. The problem is what happens when your IPod breaks?

I believe as practicing engineers and designers we have the responsibility of not just creating this new technology, but also conveying to the next generation the real fun is learning how to hack the "IPods of life", not just be content as a regimented user.

After all, a hirsute Steve Jobs holding up the first Apple computer with the promise of all the things we could program it to do with a little creativity (and a lot of hard work) was a lot more inspirational a generation ago, than the dapper corporate Steve Jobs displaying an IPod to a gaggle of stock analysts.

Where did you go Steve? You were once one of us... we miss you.





Simple Multi-tasking for small microprocessors.

As long as it has a stack, a return instruction, a push instruction, and a couple bytes of SRAM you can read and write to store task context to, with just a few instructions even the simplest microprocessor can multi-task just fine.

Millman's Theorem

Millman's Theorem states: The node voltage of a network of parallel branches, each consisting of a voltage source and a conductance in series (Fig 1), can be calculated by the formula:

V0 = (G1V1+ G2V2 + ... + GNVN)
      -------------------------------------
        (G1 + G2 + ... + GN)

Elizabeth Castro: HTML for the World Wide Web.

Now in its fifth edition, with a sixth coming out soon, HTML for the World Wide Web is becoming a classic book on designing websites.

This book is about programming web pages in HTML, but it is intended for people with little or no programming experience. Actually, "programming" is a bit of an over- statement when it comes to designing web pages. Unless you are actually designing with a language like Java script (which the author covers briefly), or PHP, designing web pages using mostly HTML is really quite simple. AND, there is the added advantage that pages you design yourself actually look and act the way you intend them to.
