Bob Lind – Elusive Butterfly

An evening pause: Performed in 1965.

Hat tip Cotour.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.

The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

    A little off-topic but vaguely connected: In school back in the late ’60s I wrote a computer program that would hide in unused memory of the mainframe computer I was working on. When it detected that the memory it was residing in was about to be allocated to a running program, it would find another unused chunk of memory big enough for it to hide in, copy itself there, and wait until that memory was about to be used, rinse and repeat. It kept track of its activities, and every 100 or so moves it would write a message out on the system console and ring the bell. The operators never did figure out what was going on!

    What does all that have to do with this song? Well, I named the program…

    “The elusive butterfly”

    Funny, I was waiting to see how you tied your computer work in with the song.

    I was about 6 years old at the time and this song among many others brings me back to that carefree time whenever I hear them.

    Elton Johns, Rock Around the Clock? I am in my basement with the smell of stale gas and an old Vespa fixing and figuring out how the thing worked and how to order a new set of rings to get it to run. From motorcycles to cars, took them all apart and put most back together. I don’t know how my parents put up with me.

    In those days it was the Sears catalogue for tools, car magazines and manuals if you could find them for information and going to the junk yard or auto parts store for parts. That in itself was a major chore. But you learned how to be resourceful.

    Today? I happened to have to rebuild my Town and Country’s entire front and rear suspension system over Covid. Either that or buy a new auto and was not in the mood to spend $50k at that particular moment.

    I sat at my computer found exactly what I needed, from brakes to shocks to whatever, got them from several sources, paid with my credit card and it ALL came through my front door by either UPS or Amazon. I did not have to go anywhere. And I watched several other mechanics who were doing the same work and got lots a great information, tips and special tools I needed. And that was GOLD. The systems on cars yesterday besides the basic mechanics have little relation to the computer controlled and monitored systems of today. It was a great learning experience.

    I needed an entire new/used rear beam axel, found what I needed in Chicago on Ebay, ordered it and had it within 5 days, it walked through my front door on the shoulder of the UPS man.

    Things certainly have changed since 1965.
