Software SDR - the RXTX+Xtall v6.3 kit

Dave Noderer — Sun, 24 Aug 2008 23:14:13 GMT

I've started construction of a HF (High Frequency vs UHF/VHF ham bands) radio that will cover ~ 1.8 to 30 mhz. it is a kit put together by Tony Parks and supported by a very active community: http://groups.yahoo.com/group/softrock40

I tell you, either my eyes have gone downhill (for sure) or those surface mount components got much smaller in the 20 years since I last worked in a lab every day.

This would be especially hard without community driven detailed construction notes: http://golddredgervideo.com/wb5rvz/RXTX_V6_3/index.htm

I'll make comments here and post pictures as I go!

I'm almost at a stage where I can point some software at this thing but a while before I will be able to do much with it.

Install Fest at Devry on 12/11/2007

Dave Noderer — Wed, 12 Dec 2007 11:53:11 GMT

WOW!! That was fun!

The room was packed with 50 people and their machines loading Visual Studio 2008 while Joe Healy (www.devfish.net) talked about various Visual Studio Features.

People started arriving at 5PM with Ed Hil from DeVry checking identiies and dna samples. Up to 6:30 PM only the 1st 50 on the list who showed up with a machine got a copy. During this time we kept a list of people as they arrived and the order they arrived in. At 6:30 we opened it up and had just enough copies for everyone!

As each person finished, we took their picture with their completed install screen which Joe will post on his website.

But... this was no ordinary presentation.. the room was "buzzing" all night as people are talking about the installs and other topics too. A few people had problems and were awared the mechanical "bug" by Joe as a prize but most were able to finish. One person had a big server box and 24" monitor! Another had an older system which unfortunately did not have a DVS player.

A few of the DVD's were bad but everyone shared and more importantly got the code for the boxed version.

Everyone got a Visual Studio 2008 T-shirt and thanks to Sherlock Technologies (www.sherstaff.com) and Mike Wasserman, we had pizza and soda.

A big big thanks to Joe Healy, our Microsoft Developer Evangalist for making this possible... Hey now we know how to fill the room each month, give everyone $600 of free software!

Email validation regex

Dave Noderer — Sun, 09 Dec 2007 11:44:03 GMT

I've been using regular expressions to validate email for quite a while. Recently I ran across a case where the email started with a number like 4thisisatest@computerways.com which was rejected.

Investigating some more I found a better expression at:

http://www.breakingpar.com/bkp/home.nsf/0/87256B280015193F87256C40004CC8C6

The expression i'm using now is:

(([^<>()[\]\\.,;:\s@\"]+(\.[^<>()[\]\\.,;:\s@\"]+)*)|(\".+\"))@((\[(2([0-4]\d|5[0-5])|1?\d{1,2})(\.(2([0-4]\d|5[0-5])|1?\d{1,2})){3} \])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))

Which works for the case above...

Although there are online and even free tools for regex testing, I still use regex buddy: www.regexbuddy.com which does cost but is very useful to me.

Review: "ASP.NET AJAX in Action"

Dave Noderer — Mon, 26 Nov 2007 11:34:57 GMT

I've just finished reading asp.net Ajax in action by Alessandro Gallo, David Barkol and Rama Krishna Vavilala. ISBN-10: 1933988142

My philosophy about javascript can be summed up in one word "yuk!" I keep hoping that the need to learn javascript will pass as the tools catch up and extend the .net dev environment to the browser client. This is happening with much better tools for debugging and deploying javascript in vs 2008. Still i'm a curious person and am embarrased to admit how little javascript I know and use.

One thing this book gave me was a very good education on javascript and the very powerful engine built into all browsers and i'm walking away with a much better apprciation for what is there and how to use it. After reading the javascript chapter i'll no longer hesitate to use javascript where required.

On the AJAX front the book does a great job of explaining what the simple sever side Microsoft tools will and won't do and explains the events on the browser side in great detail. This is further expanded to describe the interaction with server side events. This all greatly expanded my knowledge of the page life cycle at the browser end.

All of the discussions are with detailed step by step examples in code which i liked a lot.

Great job guys!
