Post WW II but pre-nuclear?

Interesting story about submarine design. Right after the war, Charles "Swede" Momsen (famous for developing the Momsen lung) was asked to figure out a way to increase the speed of submarines moving underwater. He threw out conventional surface ship design philosophy and looked at nature, specifically the Tuna as having the least water resistance. His prototype was, (wait for it) the Albacore. Naturally, naval leaders were skeptical until he challenged the navy to a race. Not only did the Albacore "swim circles" around older subs, it outran the fastest destroyer; something considered impossible. The rest is history as all nuclear subs use Momsen's "tuna"design.

Nautilus predated the tuna design. Seawolf was a variant of the Nautilus. IIRC, there was one shaped like a blimp before the tuna took over.

The bow looks like a canoe. Quite different from modern designs for sure.

Looks like a relative of the Nautilus.

Does anyone like BING?


Cherries? Yes to them. Crosby? Also a yes. M$? Don't like the pushiness of its product pusher.

Along the Great Ocean Road you come upon some places that you appreciate for their natural beauty. This was one of them for me. The erosive power of the ocean is visible on a grand scale here and on down the coastline.


Your timing was much better than mine. Great shot. There were 18 of them when I visited.

I'm sure glad they don't use that stuff any more. It was state of the art in 1950 when I had an emergency appendectomy. I puked for over 24 hours after the surgery.

Knew it would be good. I started watching Groban's shows on PBS when he was a very good tenor, before the teen hormones turned him into a baritone. The pairing with Dion had to be good.

Never worked on a 1401, the 360 was hex.


The 360 was where I worked after my Army time. The earlier machines did I/O inline. When you started an I/O operation the machine could do nothing else until the I/O completed. No overlapped operation, no O/S, single task. Those were the days.

I remember the 1401. Internally at IBM, we referred to it as a “business machine”, not a “computer” like the 360 I was trained on.


It was a stored program computer. It was considered mid-range at the time. In the large shops that I saw, it was used mainly to copy decks of cards to tape to be used as input for the larger machines and to take tapes containing reports produce by the bigger boys and print them. Many small shops used them for other things. RPG was a popular program on them. As noted above, it was a true decimal machine. It did not convert to binary.

We always said that RPG was an acronym for Repulsive Program Generator.

Although I used mainframes, the majority of my work was with four test systems running proprietary OS software. I was weened on an IBM OS-360, but the bulk was the IC and semiconductor test systems with smaller boxes. I did work in coding processors like the 8080, 8085, 6502, 6800, 6809, etc. I got into the computers at the component and bit level.
Any more I'm just basically an "end user", except for the web work.

Did you check that link? The 1401 was all decimal, while the 7080 and some other processors used a hybrid called Qi-binary.

I will believe it when I see a mother duck nurse her newborn babies. I was born in Missouri, you have to show me.

No, it is the correct spelling of a type of duck.

When did a duck become a mammal?

• I'm talking about normal run-of-the-mill computers.

• The way you wrote it sounded like you were saying that they work in decimal......

• I only have 50 years of working with computers, processors, ICs, and programming. Hope to get at least 10 more if I'm lucky. (8 of my 12 programming languages leaked out of my head over time.) Yea, I think I know how they work.
Except the newer processors, I never got into the guts of them.


I first programmed an IBM 650, the first commercially available stored program computer, as a college freshman in 1959. My career was spent working mainly with mainframes, mostly operating systems.For mre aout the 2nd generation adders see https://www.righto.com/2015/10/qui-binary-arithmetic-how-1960s-ibm.html
