Why Lisp? 3 years ago

Not sure about Common Lisp, but Julia (which is a Lisp in all ways except surface syntax) definitely does.

Whenever a cheaper Uber would come to my city, I'd drop them within a second.

Isn't the stickiness that drivers will only switch if customers use it, and customers will only switch if drivers use it?

As an aside, Julia's MacroTools.jl defines pre- and post- code walking in four lines:

    walk(x, inner, outer) = outer(x)
    walk(x::Expr, inner, outer) = outer(Expr(x.head, map(inner, x.args)...))

    postwalk(f, x) = walk(x, x -> postwalk(f, x), f)
    prewalk(f, x)  = walk(f(x), x -> prewalk(f, x), identity)
It's dead simple and obvious in retrospect, but I don't think I would have ever thought of that! I've always wondered if there's a lineage to this set of definitions. Does anyone know?

In 1973, professor Sir James Lighthill was asked by the UK Parliament to evaluate the state of AI research in the United Kingdom. His report, now called the Lighthill report, criticized the utter failure of AI to achieve its "grandiose objectives." He concluded that nothing being done in AI couldn't be done in other sciences. He specifically mentioned the problem of "combinatorial explosion" or "intractability", which implied that many of AI's most successful algorithms would grind to a halt on real world problems and were only suitable for solving "toy" versions.[15]

The report led to the complete dismantling of AI research in England.[15] AI research continued in only a few universities (Edinburgh, Essex and Sussex).

"Karl Marx was right, socialism works, it is just that he had the wrong species"

It seems that what Marx called socialism is basically communism.

By 1888, Marxists employed socialism in place of communism as the latter had come to be considered an old-fashioned synonym for socialism. It was not until after the Bolshevik Revolution that socialism was appropriated by Vladimir Lenin to mean a stage between capitalism and communism.

Is there any forecast of where the equilibrium happen? Say, if you're in a 1000-people closed society where cryptocurrency is the only thing used to buy stuff, what's the economic calculation for the long-term energy consumption? Seems like there should be papers about that...

From the link:

The CEO sold his previous company's data before founding DDG. His previous company (Names DB) was a surveillance capitalist service designed to coerce naive users to submit sensitive information about their friends.

Is that a fair statement? Can someone provide more context?

Anticipating major industry collapse, the Carrier Alliances showed remarkable discipline in aligning supply with demand as early as February; removing trade capacity from the seas by halting vessels and shipments. By doing so, the erosion of ocean rates was kept to a minimum. Basing their reaction on potential worst case scenarios, shipping carriers artificially created under-capacity. This made available space come at a premium and therefore significantly raised the cost of container shipping, stabilizing revenues for carriers.

If I'm reading this right, container shipping is an oligopoly similar to OPEC and they all banded together to reduce supply enough to raise prices, while in a competitive environment prices would have gone down due to reduced demand?

What do you mean, "map values"? There is

    [sin(x) for x in vec]
    map(sin, vec)
    sin.(vec)
which are roughly equivalent? Is that what you're referring to?

Wouldn't that (similarity matters) be very useful information to encode in the NN though? Kinda like how you can do non-convolutional deep-learning on images, but it takes exponentially more training data than convolutional deep-learning does.

while around 3/4 x faster than CPU rendering

My understanding is that for neural networks, the speedup is much more than 4x. Does anyone know why there's such a difference?

Yeah, 40 new words / day is very manageable. I used my own word lists instead of Anki, but same concept. 1000 words is enough for basic interactions (1 month) and 3000 words is generally good enough for conversation that doesn't get into the vocabulary long tail (just 3 months!) In an immersion context + some grammar textbook, it makes language learning much faster than is generally assumed.

Most people that feel they need a language class, but those are terrible for learning vocabulary. Vocab learning is best done solo.

"why don't you work 65% less and chill?" most people would look at you funny. It's not a choice. I have rent, etc.

I see what you're saying, but at the same time, at what annual revenue level do humans actually start "chilling" more and work less? 500 thousand? I'd be curious to see statistics.

Where I live (Canadian city), a lot of parents are working less, through a variety of arrangements (stay-at-home mom, consulting, part-time work, parental leave). Some of them have pretty low incomes. Society doesn't make it exactly easy, but it's certainly possible, it's just not yet the mainstream option. Social safety nets obviously help.

Wikipedia has this nice chart: https://upload.wikimedia.org/wikipedia/commons/3/3b/Heures_t... . Some countries have seen impressive reductions.

Anyway, I definitely agree with that:

A solution that relies exclusively on choice fails the smell test.

Wealth inequality, etc...
