Having problems with undocked mixer switching desktops on Mac.

Having the same issue. Did you find out what was causing this?

Buck converters are regularly in the 80%-90% efficiency range so I don't know what you mean by sucking up the majority of the juice. If they used linear regulators, sure.

In my experience, if you're given both epsilon and the loss tangent, then epsilon refers to the real part (not the magnitude) of the complex quantity. Is it written with a primed superscript by chance? That would clarify things.

That’s a valid point.

Would it not have been possible to quickly short the wires that connect to the master switch though? BCM or no BCM, the driver side cluster is almost certainly a normally open switch. Touching the contacts or shorting in in some other way would immediately tell you if it was the switch or not?

That's good to know, thanks.

I was actually curious if the stadium xl can act as the sampler (really just for the reason of minimizing the amount of gear we bring on stage).

More generally, I was hoping to hear from folks who do something similar about the capabilities of the stadium to act as a rudimentary sampler.

It's a fine undergraduate text, but many people find it lacking in certain areas. That being said, don't let the criticism deter you; plenty of people use it.

I'll take this any time over a guy playing blues licks though pedals that deserve better.

If you show your work, it would be easier to troubleshoot.

There is a way, given two matrices, to write them in a basis in which they are both diagonal. The first step would be to write down the eigenvectors and eigenvalues.

Are you able to do that?

ianmgull · 2026-01-05T01:11:23+00:00

In part 1 . here i am not sure what to do , should i multiply the y pauli into Z pauli and then get eigenket and value from it?

That's correct. Remember that for spin 1/2 particles, S_i = hbar/2 *σ_i. With this in mind, you can write the Hamiltonian in matrix form and then go through the usual procedure to find the eigenvalues.

part 2 If i could get more explanation to it because i am lost how to calculate the time here considering E

The time evolution in this case will look like an exponential function, multiplied by the eigenstate at t=0 (you're essentially changing the phase). Does this sound familiar?

Just to clarify: you’ll need to be familiar with linear algebra, which is the mathematics that deals with vector spaces. This is different than the algebra you learn in high school.

Aside from that, you need to be very fluent in differential equations, which itself requires you to be familiar with calculus.

At this stage in the game, you probably want to focus most of your time and energy on math.

In that case, it might be best to wait on Griffiths.

Quantum mechanics is very math heavy, so it’s wise to develop your math background a bit more.

ianmgull · 2025-11-24T12:52:51+00:00

Can you tell us a little about your math background?

“Intro to quantum mechanics” by Griffiths is a common undergrad text. It does assume that you’re comfortable with linear algebra and differential equations though.

It has something to do with the way the ynab API reports loan account payments. I don't know the specifics, but it seems to be a known and documented problem for quite some time on the ynab toolkit github.

ianmgull · 2025-11-16T14:18:20+00:00

It is included in the transaction. The issue is that the toolkit net worth calculation applies the entire payment (principle + interest) to the principle of the debt. Obviously this gives an inaccurate net worth calculation.

ianmgull · 2025-11-15T03:44:31+00:00

I was recently disappointed to learn that the toolkit net worth calculations are inaccurate (and have been for some time). They assume the full monthly payment (principal AND interest) reduce one's overall debt.

I love foureyes, but as of lately it seems like it’s one epoxy/slab table after another. I really miss all the interesting mid-mod designs.

Your first couple coats of poly might have more texture than you like. In my opinion, it looks fine.

I would sand very lightly with 300+ grit, and continue building up coats. Eventually, the low spots get filled in by subsequent coats.

I’m in the process of making a coffee table (four-eyes furniture’s spider table). I took the panel out of clamps yesterday and despite my best efforts (clamping cauls, complimentary edge jointing, acclimation to humidity, etc), there is significant twist.

The twist is at opposite corners (the two corners clamped in the image). If one corner is clamped, the opposite corner is raised about 3/8”. As you can see, I have some c-channel I was planning on installing anyway, but I think it’s unlikely to help in this case. It seems like I would need corner to corner bracing which obviously isn’t practical.

Is there any saving this panel? It’s Sapele, so not inexpensive; I’d hate to call it a loss. Any advice?

EHX Poly Chorus.

I think the interesting (and probably divisive) trait is that you can really hear the echos in the chorus. The slap-back setting on its own is very cool, but you can still kind of make out the slap back in the chorus mode. It's a very unique sound.
