The goal of business is to undermine competitors. It's hard to imagine a good person with such mindset.

Some kind stranger has explained the numerical solution and even provided code in Python:

http://hplgit.github.io/wavebc/doc/pub/._wavebc_cyborg001.ht...

We only need to apply it to a circle and rewrite the solver in C. This will give us a visualizer for a single frequency.

Then we run FFT, run the solver for all frequencies, observe that the final solution is a linear combination of the individual solutions and apply the rainbow coloring to corresponding frequencies.

This solver needs to be kinda fast to run at 15 fps, but luckily, different frequencies can be solved in parallel. Most likely, changing the input frequency a bit will change the solution only a little, and so we could pre-solve the frequency range with sufficient density, cache them and rapidly derive actual solutions by interpolation.

Bonus points for using complex numbers. The boundary condition in a singing bowl is u(x0, t) = A sin(Bt) where x0 denotes the circular boundary. Since real numbers are boring, we could expand the problem into the complex plane: u(x0, t) = A exp(iBt). In this case the solution u(x, t) would be in complex plane also, where the absolute value |u| is the amplitude, or pixel opacity on our visualization, and the angular coordinate arg u would be maybe color of that pixel?

Iirc, Spanner is eventually consistent.

That above isn't just an idea, it's the idea of sound visualization. It's a bijective projection between sound and shape that turns nice sound into nice shapes and vice versa. The analog sound visualizer would be an air filled glass sphere put next to speakers, if only we could see air. All you need is a performant software simulation of it. The only problem to solve here is visualizing the rapidly changing patterns in a comprehensible way. P.S. actually, we can see air patterns if we fill that glass sphere with dust. Edit: In fact, that's been done already. Find the "Yantara Jiro voice made visible". They used a cymascope (a water bowl in lab conditions) and captured the formed patterns with a fast camera. A water bowl is indeed a great music visualizer.

It's a topic that's been fascinating me for a while. Sounds, speech and music "produce" images in some sense, so visualizing sound on a flat screen is a meaningful thing to do. That parallel with the Heisenberg principle is a deep observation, I think. A few random thoughts. Colors correspond to notes: a clear red is like a clear "do" note. Volume is like size of the shape. Repetitive patterns correspond to symmetry. And that observation that there's no such thing as a "moment" if sound, and it's always about the past few seconds of sound that make it look like a music. I think this corresponds to multiple image layers with exponential decay: a sound pattern of past would look like a faint decaying background image that eventually disappears. I wish I could study this topic full time, but in our society you either make money or work on interesting things: the heinsenberg principle gas influence even here.

Then you should start with Senior Management and especially the C levels. What was that quote from the office? "There's only one person in charge in every office and his name is Charles Darwin"

I feel so much optimism in your "the rest of the year".

It was an easy way to make some initial capital. I would've done that in the banking sphere if I could.

I've been there and only learnt that this "wait to be chosen" attitude never pays off. It's rewarded, but the reward is a pittance compared to what that energy could buy.

My advise to myself 20yo would be: learn how to deal with people, learn how organizations work, build capital and get onto the money side of things; but don't let your ego get tricked into the shiny tech lead and manager titles as those are only mirages of wealth.

The right answer should be: I've build capital and started my own business.

Those 4% are 0.04% for some and 40% for others. Now the question is, if you're young and healthy, do you prefer the virus or the untested vaccine?

People with this "help others" mindset lose competition against their more ruthless peers. If you had a business, would you help others to compete with you?

The 1% contribution to others is good for the manager, because he gets to take credit for the entire team. The 10% self improvement is good for that individual, because he can leverage that into a better paying role.

One day Google locked one of my gmail accounts and demanded a verified phone number in exchange for access. Luckily, that email wasn't that important. However this taught me a lesson: next time Google is going to lock my important gmail and demand an ID, W2, routing number, full address and medical records in exchange for access and then I'll have a hard choice. That day I finally put effort into setting up my own email domain.

My favorite theory is that the Wuhan virus lab created the virus and used bats in experiments. One bat escaped and infected other bats that eventually ended up on the wet market in Wuhan. Edit: a more plausible theory is that one researcher got bitten by an infected bat and chose to hide this fact.

Apple, Google, Facebook already track everyone and everything they can: all these gps, wifi, Bluetooth and even ultrasound trackers built into smartphones exist only for one purpose. After all, they are in the business of building accurate user profiles and selling ads to them. What they do need is ability to do this openly, so they're trying to leverage the epidemics to legalize their business (ATM it's in the grey area: kinda legal, but amoral).

Is this all this tracking achieves? I personally assume that I'm infected until proven otherwise. Even if proven, I can get infected a day later. I don't need a tracker to tell me this.

Does IRS work with consultant firms? I can see how someone sets up a consulting shop, finds COBOL brogrammers and charges IRS $5k/hour.

"Mind is the great destroyer of reality" - a quote from one of those ancient dusty books. Our mind is a machine that creates models and labels for everything, to avoid dealing with the illigible reality.

They all want to get experienced corporate lawyers for an entry level associate price.

Air pollution isn't good for health: cancer, heart diseases are the leading causes of death. The virus kills a few, mostly old and sick and mostly males, but saves many, as people can finally see how clear air looks. So yeah, restarting the dirty economy machine is what going to kill millions, not the virus.

They just don't think it's harmful.

Actions like switching to paper straws?

They live in 700K houses with 3K a month payments. Mortgages will be suspended: banks don't want foreclosures. Again, the tech bros are in the top 5% by income and assets. If they sink, then 95% will have been underwater already.

I have experienced alternatives a good part of my life. The words I'd use to describe American suburbs are: quiet, green, peaceful. I get that many people are scared to be alone, but that's entirely in their heads.

I think you illustrate my point well: people are bought into the climate change talk, but when it comes to actions, they do what they really believe in.

These prices are set by the top 30% employees of the big tech firms. Unless there are massive layoffs there (e.g. 250k employees are let go) and this situation lasts for a few years (they have savings for 3-5 years usually), I wouldn't expect the prices to move.

And given that there's a limited number of good parents, there's a competition for those spots. The most skillful win.

First we pretend to care about global warming and make bold promises about how in some distant future we'll cut emissions to a more reasonable level. Everybody understands that the emissions come from the growing economy and that the only real solution is to slow down the economy.

So the virus slows down the economy for us. Exactly what we wanted, right? Emissions are down, folks in India can even see Himalayan mountains. Everybody should celebrate this, but no, our only concern is how to restart the economy and get to the new heights of pollution asap.

Gyms are now closed. The thing about suburbs is that you can be anywhere anytime, thanks to your car and garage space to store bicycles and various recreational things. If I lived in the city, I'd likely have neither and would be bound to my city block (parking isn't cheap there).
