Arthur C. Clarke died early this morning after a long battle with post-polio syndrome. The New York Times has an interesting summary of his life and major accomplishments. I’m ashamed to say that I still haven’t read 2001: A Space Odyssey, but it is on my ever expanding reading list. Hopefully I can review it some time in the near future. Clark is well known for his laws of prediction, which are as follows:

When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.
The only way of discovering the limits of the possible is to venture a little way past them into the impossible.
Any sufficiently advanced technology is indistinguishable from magic.

Isaac Asimov introduces the Radio Shack TRS-80 pocket computerIsaac Asimov introduces the Radio Shack TRS-80 pocket computer

I ran across this ad recently for an amazing new product, promoted by my own favorite science fiction author, Isaac Asimov.

Radio Shack’s TRS-80 Pocket Computer turned my dreams into a reality. Now I can take the power of a true computer with me wherever I go.
— Isaac Asimov

The marketing guys chime in a few paragraphs later.

And it can also function just like a calculator — something a desktop computer can’t do.
— Radio Shack

Wait, what!? With a standard calculator included in just about every phone that I can think of, it is hard to imagine a desktop computer ever existing without that ability. Crazy, right? Now that I think of it, it wasn’t too far in the distant past that desktop computers couldn’t be used for voice communications, something a simple phone could do. So what does $169.95 actually get you?

From Dave Dunfield’s old computer page:

The machine was actually a Radio Shack branded version of the Sharp PC-1211, which features:

Sharp SC43177/SC43178 4-bit CPU running at 256khz

1×24 character LCD display

57 key “Qwerty” keyboard

1.5k of RAM for user program storage

Pizoelectric buzzer

Be sure to check out the full breakdown at Dave’s TRS-80 Pocket Computer page

As a point of comparison, here are a few highlights of Motorola’s Droid 2 tech specs:

1 GHz processor
480×854 Pixel display (Characters displayed depends on the font)
QWERTY keyboard
8GB flash (expandable to 32GB)
Support for stereo bluetooth (not sure if actual speaker is stereo or not)
100’s of other features like camera, video capture, streaming video, and get this includes the ability to make phone calls. Sadly though, it can’t make you breakfast… yet.

Let me whip out my calculator on my i7 Desktop Computer! The Droid 2 has a 3,906.25 times faster processor (just based on clock rate, not actual computational power) and has 5,592,405.33 times more storage. That seems crazy right? The TRS-80 pocket computer came out in 1980, about 20 years ago. I wonder how people will feel about our state of the art smartphones in 2020? That is assuming we haven’t been taken over by robots gone wild, destroyed ourselves with nukes, or succumbed to a raging nano-plague. But that is all just science fiction.

I recently started reading the Cobra Trilogy by Timothy Zahn. Cobra, the first book in the series, starts off just after the beginning of the Troft war with the Dominion of Man. At the beginning of the novel, the Trofts have already conquered a two key worlds in the outer systems. The military, in a desperate move, created the Cobra program to train an elite force of enhanced soldiers. One of the first things that came to mind when I came across this series was Starship Troopers, the BOOK, not the movie. I immensely enjoyed the first few chapters of Starship Troopers with the cap troopers in the Mobile Infantry. The main difference is that instead of troopers inside of huge external mech hardware, the Cobras’ enhancements are essentially hidden, yet very deadly. On the outside they look like a normal human, which is one of their advantages.

I wasn’t sure what to expect from Timothy Zahn after the first book in this series. Johnny, the main character from the first book, now has three sons. The eldest at 27 is involved in politics, just like Johnny. The two other sons are a pair of twins, one which becomes a Cobra. I was hoping that there would be more action, but for the first third of the book I was fairly disappointed. It consisted mostly of political ramblings concerning a very controversial offer that one of the Troft trading partners proposed. They had identified a world near Troft space that was considered a significant threat. If the Cobras could neutralize this threat, the Trofts were willing to give the colony five new worlds. (more…)
