That makes sense. It's probably less "doing crazy convolution calculations on how sampled ambient noise changes as the helicopter gets close to a pole", and more "rotten wood vibrates slower"
Is this just a proxy measurement for wealth?

A food insecure developing country might be overtly reliant on staple carbs like rice and grains. Easy access to protein sources like meat could also just mean easy access to excess calories, regardless of whether a carb heavy diet would otherwise be more predictive of obesity.

Did you literally just make that up and try to pass it off as an authoritative fact?
For those of you who read this and immediately started wondering what crazy stuff this guy believes, it's "Evolution is a hoax"
If it would be better for the society, then the society should be incentivising it, or at least making the calculation sensible. Hence the discussion
I had always assumed they were doing it completely mathematically though. Like collating spectrometry readings to know what elements were present where and figuring out the temperature for blackbody emission or something, or even just linearly transforming the raw data from the spectrum the telescope can receive to the visible spectrum.

Kinda disappointing if it's really just a paint by numbers Photoshop to look nice

+1 to IC being decades behind.

I think the average programmer would be horrified if they really knew the state of modern chip design. SWEs already know how bad most software is, but imagine an entire industry of tens of thousands of people writing code (HDL/TCL), who often don't even think what they do is programming, that has evolved over the last 50 years with minimal interaction with the rest of the software engineering world.

Verilog is a nightmare. The tools are buggy. Everyone has Stockholm syndrome. Version control is considered state-of-the-art and you're lucky if your org uses it.

I've seen a lot of HDL code in my career, and there's a huge number of well respected senior engineers who think having any form of hierarchy, abstraction, or even for-loops is very advanced design practice.

The only good part is the bar is so low it's easy to standout and climb. I think the industry is in a position where it would be surprisingly easy for a startup of seasoned SWEs with a decent understanding of how to write optimized hardware to churn out competitive chips with 10x the velocity of the big players like Nvidia/AMD/Intel

I propose Betteridge's law of internet comments:

Any question at the start of a reply can be answered with, "No, that's obviously not what they said, let's try to keep the drama to a minimum please."

Darn, and here I thought he solved massively distributed quantum entanglement based networking in a one sentence throw away line on an internet forum
But it was never free speech that denied them their rights. The entire point of free speech is that it protects the rights of marginalized groups and enables them to advocate for changes in society.

Racists never needed the protections of free speech to argue for denying people their rights because those views already had widespread societal acceptance.

Now that explicit racism is no longer the norm, organisations like the Klan need to rely on free speech protections, but thats only evidence of how unacceptable their beliefs have become.

These earnest arguments that limiting speech will help protect people are terrifying.

Protesters should make a parabolic reflector with the focus about 50ft out. Pretty sure cops would stop using these things instantly
