finally resurrected Spyder IDE for Python

It took me ages but I have finally managed to resurrect my friendly Spyder IDE in Python for Mac.  I know there are lots of alternatives but this is the relatively simple one that I am familiar with and it was a great feeling to actually be able to  step through breakpoints again. Viva algorithmic publishing!

Why the USS Thresher (SSN 593) Was Lost


The US nuclear submarine THRESHER (SSN-593) was lost because standard compensation procedures to adjust for hull compression during the deep-dive on 10 April 1963 were not followed. Consequently, THRESHER was heavy (negatively buoyant) at test-depth (1300 feet) and unable to deballast because adiab...

I’m proud of these books as they present the most authoritative explanation for these tragedies and as such are essential to preventing future tragedies.

Nimble Books, the leading publisher of books about torpedo boats …

I learned today that my great uncle Chester served on PT boats during World War II. This was an unexpected bit of synchronicity as my company Nimble Books has the distinction of being one of the leading publishers of books about torpedo boats, PT boats, and motor torpedo boats (MTBs), with 27 titles in print at Amazon and on my website.

I loved this little market for quite a while, but eventually felt I had done all I could do for  a niche audience that is graying and tends to be a bit contentious.  There are no new torpedo boats, and although there have been quite a few missile boats built in the postwar era, they never had quite the  flair of MTBs, and have become less and less survivable in an era of abundant fixed and rotary wing craft and guided missiles.

I still have two beautiful illustrations of torpedo boats by the late Joe Hinds hanging in my living room.

Startup Genome

A startup ecosystem is formed by people, startups in their various stages and various types of organizations in a location (physical or virtual), interacting as a system to create and scale new startup companies. These organizations can be further divided into categories such as universities, funding organizations, support organizations (like incubators, accelerators, co-working spaces etc.), research organizations, service provider organizations (like legal, financial services etc.) and large corporations. Different organizations typically focus on specific parts of the ecosystem function and startups at their specific development stage(s).

The Old Testament as the divinely inspired Firefly

I’ve been listening to the Old Testament as I drive to work these days and am working through Isaiah right now.  The titular character, like many other key OT figures, is a prophet commenting on the life and times of his nation and culture.  Thinking like a publisher, it occurred to me that if you think of the 66 books of the Bible as nonfiction backlist, they are the divinely inspired version of “Firefly,”  i.e. a high-quality and popular series that produced way too few episodes.

At an average of roughly 1-4 books per generation, the ~70 generations between 70 AD and today could support as many as 280 additional books of the Bible, each telling the history of a nation or set of nations over a generation or  two.  The implied author would be a prophetic persona, the style Biblical, probably more like NIV than KJV.  Many challenges and opportunities in this approach.  For  example, how about a New Apocryphica covering the years 1776 to 1815?  A clever author could use this as a platform to comment about the history of the entire world, Napoleon, China, Jefferson, Sally Hemings, and all.
