The only violator I found in these exercises is the one that uses mutexes. The suggested answer involves `val.lock().unwrap()`, which is (anecdotally) common in real Rust code. An error result of a mutex unlock implies that another thread panicked while holding the lock[0], so propagating that panic is likely the right answer in this case.

I was being sarcastic. The study is very flawed at its core very much like saying blowing your nose may be temporarily effective but has been shown to eventually lead to sinus infections as our statistical models show in our mind-numbing study. The participants in said activity are already susceptible to a negative outcome.
I have to agree with you that the approach taken by the researcher is not the best one.

However... the cure that they propose is so simple and low-cost, and its effects are supposedly so rapid, that it is almost stupid to not try it.

Part of me agrees with the monetary aspect, but history and current events have shown that the medical community still doesn't even have solid footing for a lot of 'simple' type issues. Nutrition seems to be a relatively new area of study, as evidenced by the seemingly routine changes in 'official' dietary recommendations. I do think the medical profession is working to incorporate nutrition into their concepts of treatment, but it's going to take a lot of time.

The long term risk here is startups building around the startup scene and therefore becoming dependent upon the startup ecosystem itself. This kind of circularity and economic incest made the dot.com crash a lot worse than it might have been and it could happen again.

There are definite advantages to just doing what you do. I like classic markdown syntax more. Things like #foo instead of = foo =.

But I particularly like some of the ways vimwiki functions.

I like that I can type project_notes and hit <return> and it opens up a new project_notes.wiki, and then I can hit <backspace> to go back to the previous wiki.

There are more normal mode keybindings that you might find yourself using. Sometimes I remove unwanted wikis by <leader>wd, which will delete the wiki you are currently viewing (it's nice in that you can see the content then quickly delete). Renaming, too.

Maybe I can sum it up to just say I prefer the navigation and handling of new/unwanted files with vimwiki?

I tried to find the data but I could not, but I wonder, what did blender sales look like 15 years after their invention? 40 years? I picked blender because it is a useful appliance that it seems most people have one of today, and some people have had the same one for 30+ years (like my parents).

My point is, I wonder if this is just the typical performance of an appliance -- at first there is a lot of innovation and sales growth, and then it slows down as there just aren't that many new features to add and everyone has one.
I guess we'll have to find out in the coming years.

Exactly, you cannot have infinite growth. Consumerism and planned obsolescence depend on ever expanding growth.

Why can't we just have...enough? Why don't we create things that last decades instead of years? We can scale down, consume less, pollute less. We could have fewer factories that produce higher quality products. We could pay people more. We could have a minimum income so we'd get more art and entertainment instead of useless plastic shit.

It's not possible because our current heavily capitalistic world view is ingrained so deeply in the minds of everyone in high income countries.

This is a typical meta response defending the scientific framework rather than looking at the actual content. Sarcasm sometimes jars attention which was my intent. The study is doing more harm than good by reversing an effective therapy simply because it is assuming a negative correlation when the symptom (therapy) itself is indicative of the initial state of the individual tending to the more negative outcome which taints the study entirely.

I think the main issue here is that they're competing with phones and the main differentiating factor is size, I can't think of anything I'm comfortable doing on my phone but not on my tablet. Most people would rather use one device than two. Android phones have long been available in larger sizes, iOS ones have since the latest update. Perhaps a natural result of larger phones is fewer tablet purchases.
I heard similar opinions in 1998. I think it probably has less to do with the state of the industry & more to do with the state of the career of the observer.

So when the train is coming up on something like a car stuck on the track, you're right, the train isn't going to stop in time. What it can do, though, is slow down to the maximum extent possible, to give people in the car time to get a %^^&$# clue and get out of the car. The car's history, but the people might live. That's kind of a big deal.

Sun kinks are where the rail expands in the heat far enough that it can't take the stress in compression, and bends off to the side. The ties keep it in gauge, but there's suddenly a curve off to the side and back where there wasn't one before. That curve was not engineered for the track speed limit on that segment; it wasn't engineered at all.

Pull-aparts are where the steel contracts in the cold beyond the tensile strength of the steel to hold, and you get a gap in the rail. These can be (sometimes) detected electrically, by continuity. But how big a gap is it? Where is it, exactly? (Yes, you could figure it out with a time-domain reflectometer.) Can a train safely pass it? At what speed? Well, you need someone to go there and look at it to find out.

> > > It's not going anywhere it didn't go before, and it has no business going 1 MPH faster or slower past any given point on the track than it did the last time!

> > Slower trains ahead of it.

> God, I hope the people working on self-driving cars don't make the mistake of overlooking something that obvious.

Of course. But responding to it in a way that is optimal for the train is not simple. You have to take into account the speed of the previous train, the grade, the characteristics of your own train, and maybe even the weather.

Look, that can all be programmed. But it's not nearly as brain-dead simple as you make it sound.
I agree, and I appreciate the analogy. Like a blender, people know what a tablet does, what it is good for, and how to compare models. They also know what a tablet doesn't do - they're certainly not the desktop/laptop replacement they were supposed to be - and at this point, that's fine. A blender isn't going to cook a steak, an iPad isn't going to run Visual Studio.

It's probably mostly replacements and upgrades at this point, that graph is the graph of a maturing market.

> ride a bike to work.

LOL, in a rural location that you suggested to lower rent? Work is likely to be at least a 20 minute commute by car, more than 15 miles each way for sure. ( the US average commute time is 25.4 minutes) Also, biking to and from work would reduce the time you are able to spend on your altruism even further.

>How about instead of paying for an internet connection you go to a library or hang out at a coffeeshop when you need to use it. Or go in with a neighbor to get it cheaper.

Because no one is going to hire a remote freelancer without an internet connection? are you even serious? this is laughable.

>sell the house

right cutting your expenses is much easier when youre not paying rent, youre right just be homeless! then you can help all the animals you want!

>as far as the student loans go, consolidate them and pay the minimum for as long as you need to.

right, still left with a student loan payment at the end of that, so this doesnt offer any solutions at all.

> luxury of owning and operating a car and move to a region/neighborhood that has much cheaper rent (or take roommates gasp!)

So where do you have in mind? you must have something really specific in mind because i cant think of a single area with very low cost of living and very high bikeable/walkable streets - please enlighten us as to the perfect place to live.

>I don't remember me or anyone else ever saying that in this thread.

right, but youre giving advice that says "you dont need basic income to be altruistic, you can just work remotely and live somewhere cheap, then work less and use your free time to be altruistic"

Wherein the 'working remotely' applies only to a very niche set of jobs (which all universally require an internet connection and specific set of skills)

Sorry man, your hypothetical solution is plainly not realistic.

In order to help save the lives of animals thats what this person should do?

They should:

Move to a low cost of living area

Work at most half as much as you do now (and have a job that is somehow OK with that)

sell your car

sell your house

consolidate all loans

get a remote freelance job

get rid of your internet connection and only use the library

cut all your costs by 10x

bike to work

oh right, also:

dont have a spouse

dont have children

work in a remote-friendly industry

desire to perform remote-friendly altruistic work

dont save for retirement

dont get sick

dont get injured

but yeah man, this sounds totally doable for anyone who wants to support a cause, this sounds like the type of society anyone would want to live in; way worse than providing people with a basic income enabling the entire country to pursue their altruism
> If you're black, I think you wouldn't give a damn about using the word in a technical setting that makes sense.

Being offended by words without regard to context, meaning, or idea being communicated isn't really a race-specific thing, its a thing a certain subset of the population independent of race, gender, etc., does.

People in that group who are black or concerned with the black experience in America are likely to be offended by "slave" in any context (except, perhaps, an actual disapproving reference to the historical practice of slavery.)

People who are not in that group, even if they are black or concerned with the black experience in America, are unlikely to be concerned by the use of "slave" in this context.

(Since apparently we need to disclose this in this discussion, I am black. I am actually offended by people making a deal about things like this without reference to context and meaning, because it distracts from and trivializes actual racism, which remains a real and significant problem.)
I wonder if there are any libraries or tools for making simple 3D visualizations of data. Something like a 3-dimensional Conky.
OpenVZ is very unfairly left out of this history. It gave Linux Solaris-style containers in the mid-2000s, is still used in production in many ISPs and private clouds, and is still security-wise superior to cgroups, LXC, and Docker. Its security is good enough for public VPS vendor multi-tenancy.

For whatever reason OpenVZ was never merged and we got cgroups instead. If things had gone differently we'd already have safe multi-tenant container hosting.
