Re: Miscellaneous Rambling

More rambling... Even with EWR (Newark Airport) being 60 miles (95km) away the main landing glide slope goes directly over my place. They typically are at an altitude of approx 7000 ft (2100m) and depending upon cloud cover easily seen but always heard. During busy times every 3 - 4 minutes. At nigh...

Re: Miscellaneous Rambling

I can imagine the pressure increases linearly as the wing moves in one direction, and decreases linearly as it moves in the other. At the transition there could be a whipcrack effect as the wings suddenly reverse, which would cause a sudden spike. I hypothesise such triangle wave with transition pe...

Re: Miscellaneous Rambling

They flap their wings at the astonishing rate of 50Hz to 80Hz. It is audible but doesn't sound like a transformer hum. More like a buzz.

Re: Miscellaneous Rambling

I did some checking and it turns out that the hummingbirds have been spotted in my area (Lower Hudson Valley). So I filled the feeder today with the sugar solution.

Re: Miscellaneous Rambling

SWMBO is keen on watching birds, so we have bird feeders in the garden. We also have cats. And cats like to kill birds. On the other hand, birds are astonishingly inefficient at eating from a bird feeder, dropping four seeds for every one they eat, so the dropped seeds attract rodents. Which the ca...

Re: Miscellaneous Rambling

I presumed humming birds were tropical. Then I was amazed to see them outside the work cafeteria in Palo Alto. Sweet little things, but then so are the few remaining garden songbirds here. Most species of hummers are strictly tropical but some do migrate in the Spring/Summer to as far north as Alas...

Miscellaneous Rambling

Now that the warmer weather is here the migrating hummingbirds will soon arrive. In my area typically at the end of April and beginning of May. As you may or may not know hummingbirds are only found in North and South America and nowhere else. Only one species, the Ruby Throated Hummingbird, is foun...

When I was a kid Stonehenge was free and open and without "amenities"; delightful. Exactly. Somewhere around 1980, I saw the sun rise on the longest day of the year at Stonehenge from within the stones. Weren't there some incidences where some assholes damaged or otherwise defaced the sto...

I didn't know videotapes were also afflicted with sticky tape syndrome. In 1978 there was an (internal) BBC Christmas tape "White Powder Christmas" and next year was "Good King Memorex" both commemorating a tape problem. I did a little walkabout in the museum corridor at work, a...

Some house sparrows have built a nest in a 2nd floor A/C unit and Harley hears all the commotion and it's driving him nuts. He wants those birdies.

Spend much time sitting at a keypunch writing up test cases for MECL 10K array boards that were going into an interface tester for the under development 3081. The punched cards were inputted to an IBM 1130 computer. Results printed out on a 1403 chain printer. As I recall the 1130 had a massive 1ME...

Going through Berlin photos and remembered this one that tickled me. A painting of people debugging a Robotron 300, an IBM 1401 clone. The socialists knew how to do modern art. None of that abstract bollocks. Never did see a 1401 in the flesh. They were built and tested at the Endicott, NY facility...

That small brownish pile in front of that tall shrub is all that remains of all the snow piles from the January/February snows. In a few days that pile should be gone too. It originally covered that entire area to the lamp post and street sign and up to the curb. And was almost as tall as the shrub....

Re: Interesting findings on the internet

I will never buy an EV, hybrid, or any vehicle that relies upon connectivity to operate. I hope I'm dead before that choice is gone.

2004 Civic
2010 Accord
2013 CR-V

All gas. No ridiculous "start/stop". No required connectivity. No unreliable CVT. And best of all.....no car payment.
