> Is funding scientific studies where the answers are already known an effective way to change government and social policy?

A lot of the science had to be re-done because there were methodological issues in the original research, and no one was really sure whether or not the data was faked. I think it was Rick Doblin who discovered that one of the folks in either Leary's or Pahnke's studies actually ran away during the study, but because the researcher never reported this as a possible adverse event it opened up other questions about the validity of the data. It turned out the original data was basically accurate, but it wasn't necessarily a given.
We'll want to filter our air, yes. This means replacing filters, etc, which factors into the maintenance costs.
Agree. On the other hand there should be a long term appetite from large capacity hard drive from datacentres. The flow of data being captured isn’t reducing.
What's your Energy Returned on Energy Invested (EROEI) on that?

Specifically, this means if you took the gasoline you made from this and put it into an efficient generator how much electricity would you get out of it vs how much electricity you put into it to make it in the first place? This would be very useful in comparing this technology to biodiesel as a method of carbon sequestration for example. Biodiesel has other problems too such as using arable land and depleting topsoil. This comparison would make a nice slide in your deck.

Hehe it’s cherrypicked. Or cherry picking!

> The term is based on the perceived process of harvesting fruit, such as cherries. The picker would be expected to only select the ripest and healthiest fruits. An observer who only sees the selected fruit may thus wrongly conclude that most, or even all, of the tree's fruit is in a likewise good condition. This can also give a false impression of the quality of the fruit (since it is only a sample and is not a representative sample).

Switches between keeping the args for the function's full duration, or returning a closure (async or not) that doesn't hold onto them.

Here's the problem in terms of normal OS threads:

fn f<'a>(r: &'a i32) -> i32 { ... *r ... }

// oh no, I can't do this:
let i = 42;
thread::spawn(|| f(&i));

Here's the workaround:

fn f<'a>(r: &'a i32) -> impl FnOnce() -> i32 {
let i = *r;
|| ... i ...
}

// now I can do this:
let i = 42;
thread::spawn(f(&i));

In this case, and the analogous lightweight threads case you're describing, and the "implicit await" post I originally linked, the workaround forces the caller to change its syntax. From `|| f(&i)` to `f(&i)`, or from `async { f(&i) }` to `f(&i)`, or from `future { f(&i) }` to `f(&i)`.

But in async/await as currently proposed and implemented, the transformation goes from this...

async fn f<'a>(r: &'a i32) -> i32 { ... *r ... }

// oh no, I can't do this:
let i = 42;
task::spawn(f(&i));

...to this:

fn f<'a>(r: &'a i32) -> impl Future<Output = i32> {
let i = *r;
async { ... i ... }
}

// now I can do this:
let i = 42;
thread::spawn(f(&i));

You can imagine someone originally writing the first version, when all their callers just immediately `await` so it's okay if the reference sticks around. But then another caller wants to write something like the above, so they make the transformation above.

Under today's futures, all the other call sites keep working (`f(&i).await`) and the new use case starts working. Under our proposals, that transformation would break everyone just using the `f(&i)` syntax, so it probably wouldn't happen, and instead the new caller would have to write this:

thread::spawn(async move {
// move `i` in here, or worse, stuff it in an Arc, even though it's only needed for setup!
let my_i = i;
f(&my_i)
});

If you're storing A, B, and A+B, and then the file holding block A is deleted, what happens? You can't immediately remove A, because then you lose the redundancy for B. You'd need to somehow find a _new_ pair for B, C (maybe of another block in the same situation, where D is supposed to be deleted?), and write B+C, then delete A, A+B, D, C+D.

Pretty fiddly.

Rob,

I haven't seen anyone else ask this question, but I currently craft my own biodiesel and was wondering if the maker / private owner market would be able get access to buy fuel from this process?

I understand there might be tweaking of engine combustion profiles to make that happen, but I think this is exciting and would love to support by buying some of this amazing fuel without waiting for it at a gas pump...
Well, according to some statistics yes...

And there it is.

While I'm sure a study conducted by the "Institute on Faith & Giving" and published by a Moonie paper is objective it misses quite a bit by assuming that donating to charity is the only measure of empathy or generosity.

https://www.philanthropy.com/article/America-s-Generosity-Di...

Take a look a the states that rank towards the bottom of the list (mostly New England) and those that rank at the top (e.g. Alabama). Or take a look at how empathy is framed as a McCain vs Obama thing. What's missing from that sort of narrative is that Obama pushed government welfare where McCain fought it, that Massachusetts will have far more mature safety nets than Alabama. Supporting universal access to health care is no less empathetic than donating to a religious charity, the only difference is in who you trust to dole out the resources.

As a fellow gopher, I agree, Go isn't trying to compete with C/C++ on performance, it's trying to give you safety and ease of use of high level language.

I think the point about concurrency typifies this, channels aren't as fast as mutexs and semaphores, but it makes sharing code with co workers easier to reason about.

If you're in a domain where performance is still king, Go isn't trying to find a place there.

Here's a good rule of thumb: if you are a mentally competent adult and are forced to do something, this something is not in YOUR best interests.

A propos: the "herd immunity" line of argumentation is totally red herring, since the Western rate of immunization is way above of what is needed for herd immunity to be effective (defined as driving pathogen reproduction rate below one - note that reproduction rate is NOT the same as infection rate). So is the "recklessness" line of argumentation, since the chances of actually getting infected and suffering serious consequences of that are rather small. It's way more reckless to cross a street once a day.

We should have the "Say No to Totalitarians" day. A free society can tolerate some amount of foolishness - both because not doing so implies reduction of humans to livestock, and because fools sometimes turn out to be right.
> This proposal does raise another question: why not just green threads, and remove the concept of async functions entirely?

Making another reply because this is completely unrelated...

Rust already tried that. The problem is that Rust has a hard requirement as a systems language to support, at least, native I/O APIs, and the green threads implementation added a pervasive cost to that support because all standard library I/O had to go through the same machinery just in case it was happening in a green thread.

That overhead made green threads themselves basically no faster than native threads, so they were dropped before 1.0 to make room for a new solution to come along eventually. Futures and async is that solution, and it turns out to be much lighter weight than green threads ever could have been anyway- no allocating stacks, no switching stacks, no interferering with normal I/O.

The syntax could have been different, but the implementation is far better this way.
> We already give you a fine if you don't wear a seat-belt, smoke indoors, have glass containers in public places, and so on. You may disagree with all these regulations on some libertarian(ish) ground, but then we have a fundamental disagreement about when your freedom infringes on my right to be safe, and your right to be a burden on the state.

Whether or not one is fined for not wearing a seat-belt, smoking indoors, having glass containers in public, etc. is irrelevant. I honestly couldn't care less.

You are wildly confused about the purpose of deposit insurance and how bank runs happens. Banks are in the business of maturity transformation, ie accepting deposits from people who can withdraw them at any time and lending them out to people who will only repay it in a fixed schedule. It doesn’t matter how high quality and safe your loans are, if too many people start pulling money out of your bank you have a bank run on your hands because you have mostly illiquid loans on your books, not hard cash with which to pay out your depositors.

PS: Banning companies from raising cash by selling off assets makes them LESS safe and robust to failure, not more. Do I really need to spell out why?

In fact, it is _primarily_ used as a point of entropy for tracking, and does almost nothing to prevent tracking, so all-in-all it's a huge net negative. And because it's mostly turned off, turning it on to be tracked less actually causes you to be tracked more.
I might have an inkling of what this comment is saying, but I'm not sure. As written it almost sounds like the description of a ponzi scheme or a more pedantic means of saying "they lend out the money given to them by depositors" ... anyone around who could clarify this a bit?
> The new APFS filesystem is insanely fast, especially when combined with VSCode's ripgrep-based text search.

I think this must be due to the NVMe drives they use in MacBook Pros. APFS has some performance overhead that makes it slightly slower than HFS+ (but I do think you get other improvements, when copying files etc.).

I maintain my position at the time: weeding is almost never just weeding. You're there monitoring a lot of different aspects of your plants' health and progress; you need to do that whether you're weeding or not, so you might as well be weeding.

> Whatever money I'll spend on these, I -still- have to spend on something else. I only spend a tiny fraction of my disposable income.

This seems like a strange measure to me. No judgment on how you choose to spend your money - I've certainly spent money on things I later regret, and I've also spent large sums on relatively frivolous things which I don't particularly regret. There's always an opportunity cost though - I could have spent the money on something else, I could have saved more, I could have given more to charity. Over time I try not to repeat the expenditures I regret and focus more on the ones that I don't.
Counter to your counterpoint: APL did take usability into account. Dr Iverson got annoyed with how inconsistent and hard to read normal math notation was, and how many problems that caused in its usability, and invented Iverson notation to fix that - a tool to be usable by people writing on blackboards to show other people mathematical ideas.

Years later, it was used at IBM to describe what the IBM 360 computer would do. After that, it got turned into APL\360 around 1962 (i.e there weren't all that many programming languages to be familiar with, then). The book "APL\360 An Interactive Guide" by L. Gilman, 1970, has a foreword which says:

APL is clearly gaining acceptance at this time as a computer programming language. This acceptance is not hard to understand. APL is one of the most concise, consistent, and powerful programming languages ever devised. (UX is important!)

and

From a pedagogical standpoint APL has a number of advantages. The material can be taught and used in small pieces. A student can be trying his hand on simple operations after five minutes of instruction. What he doesn't know won't hurt him (a statement that cannot be made about most other languages). If he tries something illegal such as division by zero or adding a number and a letter, he gets an understandable error message and is free to try something else. Nothing the user can do will cause the system to crash. (Usability!)

and

It is indubitably true that a "clever" programmer can use these advanced operators in such a way as to produce an "opaque" program, that is, one so compact and concise as to be nearly impossible for anyone else to understand. Whatever else may be said about such programs, which are questionable in many contexts anyway, they should not be used in demonstrations of APL. Experienced programmers who have seen APL demonstrated in terms of the fantastic cleverness angle sometimes criticize the language as being hard to understand, when their criticism more properly should have been directed at the demonstrator. Such misplaced cleverness is not to be
found in this book. All operators are thoroughly covered, but there is no attempt to show off the ingenuity of the authors in writing ingeniously condensed programs.

Regen braking doesn’t use waste heat. It converts mechanical energy back to electrical.
You seem to be right about the forcing of water being much higher [1], but CO2 has a nasty property as opposed to water: it stays in the atmosphere for much longer and contributes to warming for much longer than the water does. If temperatures get really bad in future, we can limit burning fuels and all the excess water will fall back down to oceans in few years. CO2 won't do such thing as fast. So even if we can't decrease forcing due to aviation burning fuel, it makes sense to make aviation use CO2 neutral fuels to keep the concentration of CO2 low.

Sorry if I was misunderstood. glup's reply to my comment nailed it.

He started in DOI as a seasonal post-doc for USFW at a GS-5. My point is merely that the work he was doing then, much less at the end of his career, was both much more specialized and much more intrinsically valuable than a sysad working on this project. And I say that as a recovering sysadmin who's overqualified for this role.
