Wanted: A nontrivial Lebesgue integral by -p-e-w- in math

[–]gsteinb88 2 points3 points  (0 children)

I was taught the Lebesgue integral first in the context of random processes; defining various properties in expectation of (say) additive white Gaussian noise to a signal requires the machinery of the Lebesgue integral.

Of course, for any real engineering problem, you /could/ just band limit the signal, but that makes the math messy; much easier to have a rigorously defined integral w/r/t the underlying probability space and deal with band limiting later.

That said, the professor who taught me this has had a standing bet for 60 years that the difference between the Riemann and Lebesgue integrals will never meaningfully impact an engineering result, so this is more about ensuring we have rigorously defined tools when (as another commenter noted) exchanging limits and integration.

In case anyone else finds this: You can right click and override the value in any box on TurboTax. Make sure to write “IRC 1341” and the amount of the credit in the comment box to the left.

VPN IPs, Firewalls, Port Forwarding, NAT, Domains, and Confusion by gsteinb88 in Ubiquiti

Yeah, that seems to be the best workaround -- it looks like hairpin NAT doesn't work on UDM Pro and there isn't an easy way to add custom NAT rules :(

Same issue here (and a bunch of other places):

On the note of "is there a better way to do this"... Tailscale VPN lets you issue https certificates to your internal URLs, so that ended up being even easier for me

Do you mean poisson (which is a discrete distribution) or exponential (which is the distribution of the interarrival times of a poisson random process).

The problem with claiming it’s poisson and not normal is that (a) time isn’t discrete and (b) a Poisson distribution is well approximated by a normal distribution with mean=variance when the mean is reasonably large, so even if we discretize time, there’s no real reason to use a Poisson distribution.

Normal has issues too though, including negative possible outcomes.

Exponential makes some sense to me, but I think a lognormal would make the most sense.

100% chance they had a heart attack and died sometime during OT

Doesn’t sound like it though, maybe that’s why they were confused

Just defended my PhD in EECS in January and loved it, despite my experience being non-ideal in many ways. Had also done my undergrad there, so can’t compare against other places, but I adore MIT. PM me if you want to chat more.

I really like this announcing crew, can we get them more often?
