There's a type of camera that allows one to refocus images after the fact. I was looking for floral photography tips when I came across a site for a company called Lytro located in Silicon Valley. Check out the image below. If you click on different part of the image, the photo gets refocused on that part of the image. Also if you double click on the image, it will zoom in on that part of the image.

Crash!
Okay, maybe that's too over-dramatic. It was probably more like a whimper in the night. I woke up early a couple Saturdays back and noticed that the computer was left on overnight. It wasn't the blue screen of death that greeted me, but a black screen asking for a boot disk. This didn't bode well either.
Turns out that the hard drive had stopped working. A good friend tried to help me revive the computer enough to retrieve some data, but it wasn't meant to be. We do regular back-ups so we didn't lose much data, but since the automatic back-ups are set for Sunday night we had lost about a week's worth of files. This wouldn't have been too bad, but this particular week included Ethan's science project.
In the end, we recreated Ethan's hard work. This was after we loaded the OS and software on the second hard drive which was still working. We're going to see how much more we can squeeze out of this PC, but we've taken additional precautions like buying an external drive on which we are storing much of our data because we really don't trust the second hard drive after what happened to the first one.
We still may go out and buy that laptop that we've been talking about getting. And we still do have our really old PC that is older than Naomi. A couple years back we upgraded the OS from Windows 98 to XP on this relic of a PC. It only has a 13 GB hard drive so it's really not much use. The kids were using it, but the CD-drive on it failed last year. I bought a replacement drive, but have not installed it yet.

Express Lanes
This is a concept that we are preparing to test out where I work. The project is to provide solo commuters the option to use carpool lanes for a fee. This allows more people to be able use the freeway without having to widen the freeway.

Are You Ready to be a Traffic Engineer?
Check out this game from the University of Minnesota to see if you have what it takes to be a traffic engineer. Of course, in most cities the timing of signals is controlled by a computerized system.

Plasma or LCD?
Not that we are in the market for a new set, but here's what is the current state of the "Should we buy an LCD or plasma high definition television?" question.
If having a truly cinema-like experience is important, then plasma displays are slightly better. The main issues with plasma sets seem to be image glare on untreated diplays especially in bright rooms. Also, although for most good plasma displays this is a non-issue today, there is a possibility of image retention for some displays.
LCDs on the other hand come in a wider variety of sizes (e.g., plasma displays less than 42 inches are not available) and images are quite comparable to that from a plasma display. The areas where LCDs do have possible weaknesses compared with plasmas are limitations with viewing angle, blacks not being as dark, and motion blur.
The top plasma display makers are Panasonic and Pioneer.
The top LCD display makers are Sony, Samsung and Sharp.

Cell Phones
If you're in the market for a new cell phone, here's a site that you should check out before shopping.

The Keitai Denwa
One of the biggest changes that Dorothy and I noticed in Japan since our last visit nine years ago is the proliferation of cell phones, or as they're called in Japan "keitai denwas." But then again this change should not be that surprising - even here at home cell phones and their use have changed considerably. We only got cell phones seven years ago before the birth of our first child so that I would be reachable any where, any time.
My first memory of cell phones were objects that we called "car phones." There were a few people in my office where I worked 15 years ago who had them. They were usually grey, brick-shaped phones that were powered through the cigarette lighter in cars or could be operated on their own. Somewhere in the past 10 years the term "cell phone" has become the generic term for these phones. http://en.wikipedia.org/wiki/History_of_mobile_phones
In Japan, these phones are called "keitai denwas" or more simply "keitais." The word keitai means portable with the kanji characters for keitai coming from KEI meaning "carry" and TAI meaning "belt." http://www.cjvlang.com/Writing/writsys/signs/keitai.html
This literal translation of keitai would be a better description of cell phones here in the U.S. than in Japan. It's much more common to see cell phones carried on the belt here than in Japan. Most of my male relatives in Japan seemed to carry their phones in a pocket. Other observations include:
1. Not as many variations on the shape of the phone (many seemed to look like my Mom's Cingular Erickson phone).
2. High quality digital cameras and the storing of photos on their phones seemed to be more common.
3. Many of the phones were decorated with tags like we have on key chains.
4. Much more text messaging, perhaps even more text messaging than phone calls. I think text messaging is less expensive than making a call and perhaps much of what can be communicated can be done so through short messages. Another reason for the popularity is its outgrowth from the popularity of pagers in Japan from the mid-80s to the mid-90s. http://en.wikipedia.org/wiki/Japanese_cell_phone_culture#Teenagers_and_keitai
5. Cell phone usage in cars is not allowed. There are also signs in may establishments that request phones to be placed on "manner mode." Trains have signs requesting phones to be turned off near senior priority seats because of the risk of cell phone radio waves interfering with pacemakers and other medical devices. Why isn't this more of an issue here in the U.S.?http://en.wikipedia.org/wiki/Japanese_cell_phone_culture#Negative_aspects
