323··on Overhead of Python asyncio tasks
Waste allows scale, that's a general civilizational rule.

You wouldn't be able to write your comment if the browser were written in extremely efficient assembly code because it wouldn't exist.

NASA and every big organization also has a lot of waste, but only that way you can get to the moon.

323··on Overhead of Python asyncio tasks
It makes concurrent programming much simpler than using threads.

Very few locking and care is needed with asyncio, as opposed to using threads. Race conditions are basically not a thing if you write reasonably idiomatic code.

It might be (or not) faster than using threads, but that's not the main benefit in my view - this easiness of use is.

Or you can get payed to do your activism. There are groups paying for activism on all sides. Just go and find it for your side.

We are a long way away from worrying about this.

323··on Pandas 2.0 and the Arrow revolution

   prices.loc['2023-01'] *= 1
You can always do df.to_pandas() ... prices.loc['2023-01'] *= 1 ... from_pandas() :)

More seriously, you are right, this is a tough one to do in polars. Polars seems to want to work with whole columns at a time, it doesn't give you write access to row sets.

That's not very reassuring. Privilege escalation on Windows is a well studied subject:

> consider also overhauling the API besides the internals

This never happens. Angular does not become React, React gets created instead. CoffeScript does not become TypeScript, etc.

There is too much baggage and backward compatibility that prevents such radical transformations.

Instead a new thing is created.

323··on Pandas 2.0 and the Arrow revolution
Polars is more verbose, but simpler. It's core operations "fit the brain". I've used pandas for years, but I still have to regularly google basic indexing stuff.

No, the media negated it because all the notable scientists and publications (Nature, Lancet, ..) said it was a crazy conspiracy theory.

WebGL is very low-level. And there is no good Flash-like editor where you work with shapes and animations and which compiles and outputs to WebGL.

This article is omitting a lot of facts, like the multiple times Russia tried to implement coups in Moldova to bring Russian-aligned people to power.

> we used 2048 A100-80GB for a period of approximately 5 months

Do we know how much total energy a human consumes from birth to 20 yo? Something like 2000 calories integrated over 20 years. How does it compare to the GPUs above?

Wolfram Alpha:

- human - 17 MW/h ((2000 calories per day) over 20 years in MWh)

- GPUs - 3000 MW/h ((2048 * 400) W over 5 months in MWh)

We still have the edge.

LOL, I'm being downvoted, I wonder way. Some don't like the question.

The directors which decided to rely on Russia got millions in bonuses. Just like the ones which pivot now to China will.

Classic incentive duration mismatch. Short term bonuses vs long term profits.

It's complicated, first there is not just one H5N1 virus, there is a family of them.

I bet 50% mortality will really focus the mind of the anti-lockdowners.

Don't worry, surely there are some virologists in some lab mapping right now exactly what mutations would make it very transmissible between mammals. So that we are ready and prepared, of course.

323··on Our reality may be a sum of all possible realities
Why wouldn't summing all possibilities be the simpler solution?

Thing about Monte Carlo simulations - it's simpler to just try all possibilities than to figure out what is the formula of the correct result.

Neural networks also work like that - you randomly do things and propagate errors with simple rules instead of figuring out the complex formula that would give you the answer.

There seems to be a lot of power in summing up all the things.

If our universe is a computation, our practical experience seems to suggest that a Monte Carlo like simulation of it would be more efficient than a closed-form formula.

323··on Shimano’s three-pulley rear derailleur could revolutionise drivetrain design
But you still don't see them on very pricey bikes ($15k+). So they are very expensive, without being premium, which is a weird place to be.
323··on Usage-based pricing isn't always best
Why not offer two types of pricing, a flat (expensive) one and a usage-after-the-fact (cheap) one.

Like in Electricity markets - you can either get market pricing (cheaper, but very volatile) or fixed price.

> amazed with hub gears

I've never seen hub gears on light or even medium weight hybrid/city ALU bikes. Which suggests there is a problem with hub gears. Maybe they are heavier, or more expensive, or harder to maintain, but they are not popular.

323··on New headless Chrome has been released and has a near-perfect browser fingerprint
People are paying $500 for bots used to buy the latest Nike/Adidas/... limited edition sneakers. Or videocards a few years ago (for crypto mining).

It's a whole industry.

> If we consider a user base of ~175 users, and a minimum bot price of 200 euros (175 users x 200 euros), then the bot developers made at least 35K euros (~$37K USD) in initial bot sales.
