Yes, that's what I did and what I reffered to in my post (I forgot that it gave you C(2) and not just C(1), it's been a couple of months since I worked on this). There are still visual artifacts, they're just smaller. Even Perlin's paper on this showed a picture of the artifacts that the 5th degree polynomial still generates.

I've implemented 3D perlin noise recently and was surprised that the lighting was always off on the created model around the grid lattice (the model itself was continuous there, just the light was not correct). After a delightful couple of days debugging it, I finally learned that Perlin noise's derivative is not continuous around grid lattice, which makes normals not continous there (as normals are orthogonal to a tangent, and tangent is based on derivative). It's possible to improve it by cleverly changing Perlin's wavelet function, which makes the noise C(1) (derivative is continuous, second derivative is not) - this makes the visual artifacts smaller, but they don't go away.

It's actually pretty hard. The most expected scenario after pumping hundreds of billions into a cleptocracy would be for most of that money to get stolen with little to show for it. Not to build a machine that stopped Russia. What Ukraine authorities managed to do, given the country's state (the coruption is truly mindboggling), is remarkable.

Public transport in communist Poland was horrible because it was severely underfunded. Remember that Poland bankrupted in the 1981 (when the West put sanctions on the country after the Jaruzelski's "coup", and sanctions kiled the economy) the whole decade was kind of surreal in terms of state's lack of funds and decrease of living standards.

In my country studies are free, which means humanities (like "world literature") are full of young people who had no idea what to do with themselves, so they chose a major in something vaguely interesting and not very demanding, mostly so that they get to extend their youth by a couple of years (as parents will often support them while they get their degree, which means not having to work).

Due to population distribution, you're most likely to be born in a poor country. And, in those countries, you're way better off being born in 2026 than in 1970s (to be able to watch when the Internet was starting). Chances are, if you were born in China, India, Nigeria, Malasya etc. you wouldn't even hear about the Internet anyway.

No, not boycotts.

The influencial youtubers I think of actually can shape political debate and thus policy - what they say, if it gains enough popularity, sometimes seeps into the political agenda of the ruling party (which is always looking to "score points" with the voters and has its ears to the ground listening which issues and points people are currently responding to). It's basically like being a columnist of an influential newspaper, except you don't need to have the right connections to become one.

Legally, you can do a lot more than ignoring. If you have any talent for it, becoming an activist (say a youtuber) rallying people against whatever you believe is bad, can be pretty powerful. A single person (again, with some talent for public speaking etc.) has a real chance of making meaningful change this way.

SF Bay Area (land) has population density of a third of New York metro area or an eight of Tokyo metro area. The population density does not justify a world class public transit system. Not to mention there's a large body of water in the middle, which precludes building a lot of connections.

but if I created a lovable comic character and someone offered me a dumptruck full of money

would like to think I have integrity, and I think I do to some extent (there are certain types of companies I will not work for e.g. casinos)

What if a casino offered you a dumptruck full of money?

Voxel Space (2017) 2 months ago

Voxel below topmost were not „ignored completely”. They were absolutely rendered in e.g. steep cliffs.

How much would it cost to build out batteries which cover entire continent's electricy needs for say three weeks (as there can be 2-3 week lulls of no wind and no sun in Europe in the winter)? Cause that sounds like a lot of batteries. Not to mention, if a freak 4 week lull occurs, we'll go back to Middle Ages for a week.

Typical salary for a senior dev is around 20-30k PLN per month, which translates to $65k-$100k per year (gross). Also, a lot of devs do a little bit of tax avoidance that is currently not persecuted, which allows them to pay total taxes below 20% on that amount. So, your take-home pay is $50k-$80k.

I'd say it's a country that builds a ton of infrastructure, at the expense of living standards of common people. The money from infra has to come from anywhere, and an all-powerful central government can just redirect the stream from consumer spending into building out infrastructure. Whether Chinese are happy about it, you'd have to ask them.

Aren't there health insurance plans with a high deducible (say $10k) that are quite affordable? In your early retirement, you can cover catastrophic health failures with them, and pay for everything else out of pocket.

No, it isn't. No LLM platform ever will be. No platform or vendor of any kind ever will be, if we are being honest. One cannot set up a business where another company becomes critical to your operations.

Most of companies in the world have done that with Windows, though.
