about electronics

IEEE is mostly stuffed-shirt academics, not the place to find interesting opportunities.

We were forced to join as EE freshmen. I got out as soon as I could.

They do it by the minute. Ships care about weather, not climate.

Sofar is also building a sort of overgrown surfboard, with solar cells and an electric prop, that can go where it wants and stay out longer than a passive buoy.

Neither. I use the NTCs to temperature compensate my instant-start LC oscillators. FR4 has a radical positive TC. I typically wind up with a parabolic frequency tempco, flat around 35c.

Most things work like that. Compensate the first-order term, and what's left is mostly second-order.

Sounds like a typo. They meant 32/6.

Actually, it is more likely overconfidence on their part -- thinking they understand something when, in fact, they are largely clueless. "Enlightenment" possibly coming when they find they've shot themselves in the foot.

Software is repeatable (in the absence of hardware errors). So, seeing "something" once means there is some condition that caused it to manifest. Your inability to reproduce THAT CONDITION doesn't mean the problem has gone away -- you're just being lazy and HOPING for the best.

Do you see standard library (et al.) functions accounting for the fact that the address space "wraps"? Most will gladly do what they are told -- regardless of how nonsensical it may be (what does it mean to clear the last 100 bytes of memory starting at LAST_MEMORY_ADDRESS - 72?) Or, trying to print "(unsigned) -1" digits with leading zero suppression? Or, ...

How much stack does your piece of code (AND EVERYTHING ON WHICH IT RELIES) *require*? Do you even know how to go about getting a DEFINITIVE answer? What (specifically) will happen if you exceed that value?

Well, I went there for the free pizza and beer, and for the view and to meet tekkies.

Sofar has been around for years and claims to have revenue. Gorgeous offices.

They seem to be one of the lesser-insane startups.

Yikes. Panic.

I talked to the founder, an interesting guy. He's a surfer and scuba diver and has always loved the ocean.

I don't know the details. He is using an RP2040 CPU and, I think, cell phone type sensors.

Their real focus is on the software. As is typical these days, computer screens outnumber soldering irons about 20:1.

I saw the same thing touring the Cornell EE school. I counted 30 computer screens and one oscilloscope.

"Straight-line winds" are bit improbable. Weather systems are essentially circular because of the

"House-sized boulders" deposited on beaches don't have to come from wave action - whenever the Greenland ice sheet decides to slide off into the sea, the ice-bergs created can contain substantial "iceberg rafted" boulders, and these show up as "erratics" on the floor of the North Atlantic.

Your capacity for making implausible and insulting predictions is unlimited. If there was anything useful going on around Sydney I'd probably get to hear about, and I would try to exploit it if I did. I do go off to meetings from time to time. I got to see the University of New South Wales quantum computer a few years ago. The then New South Wales chair of the Royal Australian Chemical Institute was there too (I'm a life member of that crew too, so I did recognise him).

So do lots of confidence tricksters.

To you.

So does every successful confidence trickster.

The kind of electronics which everybody wants to help with aren't exactly demanding. If everybody can see stuff that needs improvement you haven't got off to good start.

Not a good characterisation of the people I work with. There are quite a few lectureres and professors, but none of them strike me as stuffed-shirts. The Italian female professor who has now gone to the European academic semiconductor fab - IMEC in Belgium - stuffed a shirt quite agreeably, but her expertise was in insulating layers for semi-conductor fabrication, and Australia doesn't have any semiconductor fabs left.

Before the IEEE kicked you out?

But it still doesn't look at the deep return currents.

The instant start LC oscillators are a bad idea. You can get much better timing out of a continuously running oscillator - you need two interpolation circuits rather than just one to find out where your interval started as well as where you want it to end, but the lower jitter on the continuously running oscillator makes that a better choice.

You can't make a silk purse out of a sow's ear.

Your ideas about good circuit design don't entirely align with mine. Your rejection of the classic common-base two transistor monostable does come to mind. It didn't provoke any kind of screaming fit from me, but I did get lots of instruction about not losing my temper when I was a kid.

The nearest we ever got to a job interview had you forwarding a private e-mail from me to you to Jim Thompson.

If that's an example of your interviews technique, anybody with the smarts to get a Ph.D. would write you off rather rapidly.

Search on “Coriolis effect “. Straight-line winds from the poles to the equator, forsooth.

We have some pretty bad house-sized houses deposited on the beaches here already.

Uncle Al says we'll have another ice age soon.

That wasn't what he was saying, though Breitbart may think it was - they aren't exactly well-informed.

The film "The Day after Tomorrow" was about the Gulf Stream (AMOC) shutting down, which wouldn't start an Ice Age, though Northern Europe and the east coast of North American would get pretty chilly for about a thousand years or so.

It would be a re-run of the Younger Dryas, which was a 1300+/-10 year long episode that happened at the end of the last ice age.

Technically true about the improbability of "straight-line" in the meteorological sense. But the winds will be driven by the atmospheric temperature gradient, now much, much steeper, and that is roughly independent of the Coriolis effect.

The emphasis on a "privately owned network" raises questions about why they want to avoid using existing, accessible government data. Maybe they're planning on serving customers from "rogue nations."
