See https://www.aircela.com/ and many other e-fuel startups, that one makes a very pretty image of a "personal fuel synthesizer" which makes about a gallon of gas a day which is about what my wife and I use.

Cool! They have the numbers, too. Their system needs electricity for electrolysis, 75kWh per gallon of fuel. Compare to 0.24-0.87 kWh/mi for electric cars.

It's cool that they released the software as open source!

local CO2 emissions. This has not affected pumping of oil, and since we aren't even able to store much oil, that means it's getting burned. That makes it clear the global effect must be very close to zero. And for CO2, only global matters.

You're essentially arguing that reducing demand won't reduce supply. It may not do so immediately, but certainly over time it will.

For example, there are oil fields that are unexploited because they would not be profitable. If demand rose, prices would rise and new wells would be opened. The reverse is also true.

This is great news for WASM, and looks like the Microsoft team really put in a lot of effort!

I wish there were a somewhat acceptable, though controversial, way for us to distinguish between good and evil like how success is defined by disposable wealth. You can argue that society does not see it that, but there is no absolute way to denying it.

Are you sure?

Aside: I keep hearing of "AI bot" detection, but how does such a detector know that the script (if I may use this term instead of bot) uses ML (or some similar technique that falls under the AI umbrella) and why is that worse than (or noteworthy relative to) one that doesn't in the context of blocking?
two_handfuls · a month ago
It's not that it uses ML, it's that it is operated by an AI company. It so happens that those companies are hostile and are ignoring robots.txt and sending requests way faster than would be polite.

I’ve always been surprised that we don’t have a really widely supported construct in programming that is like a for loop, but with no dependency allowed between iterations. It would be convenient for stuff like multi-core parallelism… and also for stuff like out of order execution!

Not sure how “break” would be interpreted in this context. Maybe it should make the program crash, or it could be equivalent to “continue” (in the programming model, all of the iterations would be happening in parallel anyway).

I vaguely feel like “for” would actually have been the best English word for this construct, if we stripped out the existing programming context. I mean, if somebody post gives you instructions like:

For each postcard, sign your name and put it in an envelope

You don’t expect there to be any non-trivial dependencies between iterations, right? Although, we don’t often give each other complex programs in English, so maybe the opportunity for non-trivial dependencies just doesn’t really arise anyway…

In math, usually when you encounter “for,” it is being applied to a whole set of things without any loop dependency implied (for all x in X, x has some property). But maybe that’s just an artifact of there being less of a procedural bias in math…

They're not in the language proper, but "parallel for" is a common construct. I've seen it in C# and Rust, but I'm sure other languages have it too.

It may be a good idea to use a framework with explicitly stateless "tasks" and an orchestrator (parallel, distributed, or both). This is what Spark, Tensorflow, Beam and others do. Those will have a "parallel for" as well, but now in addition to threads you can use remote computers as well with a configuration change.

Interesting, but I fail to see how it can work exactly. If there's a function awaiting something, how is the function called then? Will it look like calling any function, but it might not return immediately? But then there's also examples of calling aio.delay(1000) which does return immediately. I think my question is ultimately, what's the return type of a function containing an await?
two_handfuls · 2 months ago
Well I'm not the author so I can only guess the answer to your ultimate question: if a function contains an await and returns a string, my guess is that the return type would be "string".

After all, that's what "colorless" implies to me: it's possible to take a non-async function and make it async without having to change its callers. This suggests we don't change its return type.

One neat thing I see this has is colorless async: https://fubark.github.io/cyber/#colorless-async. However this is a work in progress as their async isn't multithreaded yet.
