Readers of my previous blog entry "What Light Through Yonder Flashlight Shakes?" have asked for details about the science project that caused my son and I to look into shake flashlights in the first place. Here goes.

I bought a new toy the other day, a netbook.  It's an "ASUS Eee PC Seashell 1005HA-PU17-BU Royal Blue".  Although I recently confessed to being a late adopter of flat-screen TVs (actually, I still don't have one), I think I can claim to be a bit of an early adopter of netbooks since I don't know anybody who has one.  Here are my initial impressions.

Fred Allen once said "Imitation is the sincerest form of television."  With 3D becoming increasingly mainstream in movie theatres, television inevitably must follow.

The technology is here.  Flatscreen TVs long have had oversampled frame rates, LCD shutter glasses are a simpler technology than the LCD television you might watch through them, and Blu-Ray players hold oodles of data.  In fact, I'm surprised 3D TV didn't come out sooner.

I recently helped a lad put together a school science project that involved the idea of using "shake flashlights" as a power source.  The idea seemed like a good one when he first proposed it.  But when we began to implement it we immediately ran into a quite unexpected problem: it's impossible to find shake flashlights in retail stores.

I ran into Gall's Law recently, which states: "A complex system that works is invariably found to have evolved from a simple system that worked. The inverse proposition also appears to be true: A complex system designed from scratch never works and cannot be made to work. You have to start over, beginning with a working simple system."

 I decided to try to speed up my Vista laptop in place of - or at least before - upgrading it to Windows 7.  That would allow me a fairer comparison to the speedup after a clean install of Windows 7.  And that led me down the Yellow Brick Road of the Vista defragger.

I spent part of the day today trying to figure out whether I want to "upgrade" from Vista to Windows 7.  I run Vista on a Toshiba laptop and I've had a lot of problems with Vista: it's really a complete piece of garbage. 

I've recently been learning Matlab, and I thought it might be fun to record some of my impressions of it as I go. First, a little background. I've been programming for many years, and know a variety of programming languages, including FORTRAN, C, C++, Perl, Python, and a few assembly languages. My preferred languages are Python and C++, depending on whether an application can be interpreted or must be compiled.

Well, dspGuru will be ten years old in a few days. It hardly seems possible. It's interesting to look back on how it turned out relative to what I was hoping for when I launched it. dspGuru has mostly been a success. At the most basic level, it scratched an itch that I had - and still have - to spread the gospel of DSP. Of all the missions one might adopt to make the world a better place, helping folks learn DSP pales in comparison to ending polio and squashing sugar ants. But we all need a mission.
