Microchip PIC18's - nice
On January 1st, 2003 In Technology
I've been doing some PIC programming
lately. I really love Microchip's parts. Simple, cheap, effective.
The 18F series is my current love. The 18F458 has lots of flash, a
CAN controller, serial an a little RAM. I wired one up to a Cirrus
8900 ethernet chip and write a simple TCP stack for it. Amazing huh?
Other have done this before me, but
Xilinx Virtex II Pro - wow
On January 1st, 2003 In Technology
My vote for the cool SOC of the year (2003) is the Xilinx Virtex II
Pro. It's a PPC 405 with a giant fpga. It's also a lot of IP which does
all of the normal things like ethernet, serial, etc...
Maybe everyone knows this but looking over the interface docs I was having
some major deja-vu from some work I did for IBM a few years back. It

What hath venture capital wrought?
dateline 2000: Way too much money chasing to many bad deals. Way too
much money put into marginal or even bad ideas. Insane valuations.
Insane investments.
dateline 2002: many, many, many failed startups. everyone is running
scared. M&A has slowed or stopped. IPO's have
SOC's coming like a train - woo hoo linux
On January 1st, 2002 In Technology
System-on-chip cpu's are coming like a train. The first one I spent time
with with Motorola's 8xx line, the
860, 850 and 823. These chips had
all the peripherals on the chip on one big melange. Static memory interface
for flash, SDRAM interface for memory, an MMU, serial ports and built in ethernet.
Needless to say it ran linux well, thanks

"Metricom to close Ricochet"
This is sad. I thought that this idea was strong enough to live in
some metropolitan areas at least. The problem (IMHO) is that VC's
often kill the idea by pushing the "big score/massive expansion"
rather than the "slow but sure wins the race" strategy. I can't tell
you how many CEO's I've talked to recently
Wearable computing
On August 1st, 2001 In Technology
Would you wear a computer? I'm not sure I would. Except for maybe my
wrist watch, cell phone, pager, oh, and the keys to my car. How
about one which had a 600x800 eyepiece? or one that had an audio
earpiece/microphone? Seen anyone with a phone and ear microphone
lately? (they really work well - I tried one).
There are research folks all
Taxes

My accountant told me he had clients break down and cry
in his office this year. On one hand I totally understand. On the other, I'm
not sure I do. Did people actually think that money existed? What if everyone
had tried to sell their CSCO or Redback shares at the height of the
market? The price would have dropped. There would have been
USB - truth is stranger than fiction
On December 1st, 2000 In Technology
A friend warned me when I said I was going to work on a USB controller. He
said it was a huge spec and it would take me months to figure it all out.
I didn't believe him. I went off to write a host controller for the PowerPC
8xx chip. Six month passed. Turns out he was right. Still, it was fun
to learn the entire spec from top to
