Hi Tim,

I'm thinking more of the job hunt after the fact.  Have you ever walked into a job interview room filled with kids who look at you with the unspoken message "Why aren't you greeting customers at Wallymart?"

The worst is when unemployment benefits are about to run out and the Unemployment Insurance Commision sends an email to the effect that "Due to your length of unemployment, you might be looking for a career in an unsuitable field."  Duhhhh...yeah, maybe I'll go flip burgers.

Thank you for your appreciation of my past work.  I apologize for not responding sooner.  The people I worked with in my last 2 jobs were good people, and I certainly will not say anything against them.  At one there was a large layoff due to business conditions in which many people were let go.  At the other, it was a contract position, so it was only for a limited time.  In neither case was age discrimination involved.  As for a new position, I prefer to think the best of people, so I won't bring it up there either.

Good story, impressive fix.  Except at the very end in the author's bio "He has an MSEE from CWRU, and a BSEE from MIT.  He is currently looking for a new position."

Somehow I get the impression this gent has been "put out to pasture" so to speak, and today's bright young corporate HR people refuse to consider a competent engineer with 29+ years of experience, no matter what the track record.  What they see is someone in their 50's.  Age discrimination is alive and well despite being illegal.

Tim, perhaps you might comment on this, is my assessment accurate?

Diagnostic smarts

Pretty hairy stuff to me Tim (I'm doing some blogs on the PICAXE at the moment and you make me feel totally inadequate :-)  but I found it very interesting as my wife had one of these scans done just the other day.  I am constantly amazed at the "smarts" of this kind of medical diagnostic equipment.  As your machine was mid-1980s I would assume that they now use n times more memory and processing power and don't have to use tricks like yours.  But I take my hat of to you!

old notes
Caleb Kraft   10/21/2013 5:02:40 PM
You never know when those old notes are going to be a life saver!

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
