This is nonsense. The probabilistic theory suggested might apply well to the examples they gave of Broadway plays and world leaders in power, which both have natural limits on their timespans, but it's not at all obvious that applies well to guessing the length of human civilisation. Crucially that is not well informed by its length so far; neither of the threats they quoted earlier (nuclear annihilation and catastrophic global warming) have been a potential factor for more than 0.1% of the 200,000 year figure they're using as our lifespan as a species so far.

And they ask in what way we are different to Neanderthals or Homo erectus in terms of longevity; well neither of them ever came even slightly close to wiping themselves out with nuclear weapons, or developing space travel to allow them to survive global catastrophes. Comparing their longevity might be useful to predict how long we would survive from tens of thousands of years ago when our ancestors lived in caves in Africa, but it's utterly different to trying to predict the longevity of the civilisation we have now.
Probably most productive to read the Doomsday Argument[0] Wikipedia article to see something similar argued.

Skipping over all the usual analogies and theoretical theoretical side this article provides a simple discussion of the problem domain of monads and how they provide an elegant solution. It does this using common problems like callback-hell and null-check hell, and using code in an imperative language making it straight forward to recognize patterns in code the reader has likely seen.

Easy to follow, this type of presentation is really impressive and is what allowed the motivation for monads to finally ever seem useful and practical.

I wish items like this were presented more often than the usual backwards, theoretical presentation which doesn't really help a reader much.
I think his argument is wrong and the fallacy comes when making the hypothesis the is a "50 percent chance that it was somewhere in the middle portion of the wall's timeline". It seems like a relatively reasonable assumption in that context but it is actually very arbitrary.

Imagine applying his reasoning to any building that has just been completed. Say we visit it the following day, make the 50% hypothesis and then conclude the building has a 50% chance of falling within 8 hours to 3 days. Obviously the conclusion is wrong as vastly more than 50% of buildings last longer than 3 days. We see in this case that postulating that there is a 50% chance that we visited the building somewhere in the middle portion of the building's timeline was completely unreasonable - we know from experience that buildings tend to last years.

So basically his estimation of when humans go extinct derives from a guess that may or may not be correct and in any case seems very arbitrary.
That is not the only variable...

Yes, from the title I assumed exactly that. I spent several minutes reading the paper till I realized that different students received different tests which made this much less interesting.
Right - they statically link which means that you typically don't have to worry about shared object dependencies when moving the binary around. You just have big binaries. If you use cgo (integration with C-code and C based libraries) then you are back to *.so versioning problems.
These are neat but it's a bit odd to call heapsort and mergesort bizarre. Sure if you just think about them as operating on arrays they would seem strange, but if you think about them more abstractly they make complete sense.
From that wikipedia page:

> "Because it can be applied to completely arbitrary distributions provided they have a known finite mean and variance, the inequality generally gives a poor bound compared to what might be deduced if more aspects are known about the distribution involved."

In the situations cited in the article, we are dealing with both an unknown mean and an unknown variance and therefore an unknowable distribution. So while Chebyshev is "weaker" than a Gaussian distribution, it's still a distribution.
What was the percentage of Jewish applicants passing these examinations despite all these efforts?
Ha interesting. OK taking this a bit too seriously -- it seems like there should be a better reward than that.

Suppose you actually know all the answers on the test, and you know you know them. You have two choices:

1) Mark them all correctly

2) Mark them all incorrectly, based on your knowledge of the correct answers

There's no incentive for doing #2, because you get an A either way. But if they offered a better reward, like being able to skip the next test with an automatic A, then #2 would look appealing.

Another way of looking at it: instead of imagining you're at a random time in humanity, imagine you're a random human. The number of humans on earth has been increasing exponentially, so if you pick one at random they are most likely going to be from the last two centuries. This skews the results by making it more likely that the prediction is being made at this particular point in time (or a bit later if the population continues growing), which means that it is a non-uniform sample.
Well. If you just want to confirm the order you should be calling methods, you should be able to figure out how to use any of those APIs based on Swift examples.

If anything, Swift examples are more necessary because there's tricky things you can do with closures, manp, flatMap, etc.

ObjC is very straightforward.
I ran into this recently. Almost the exact same usecase, although I had canceled line items, instead of posts.

There is one usecase where this works, though.

class Post < ActiveRecord::Base
default_scope { include(:author) }
end

In my case, the parent model depended on the child-model to be present when running a few methods (calculating the total for line items), so I decided to do this for eager loading.
Wow. That's truly pinpointing it! "Between 5k and 8m years from now." If you're willing to accept "between 100 and 10b years from now", it's not-quantitatively-but-qualitatively equivalent to any living human but even better odds, I'd put them at 99.9%.

IIUC, SiFive is selling the ready-made "hard IP" [1], that means a compiled netlist that has been laid out at a slightly-abstract-but-almost-mask level.

All this is manual work done on top of a netlist generated using the open-source Rocket chip generator [2,3] (SiFive people contribute to the upstream repository).

Let's make a Wordpress analogy: SiFive is a big contributor to Wordpress and does most of the work upstream. At the same time they sell you preconfigured server images for your blog with Wordpress, nginx, varnish and postfix almost ready to go (few settings like IP, hostname and WP theme are still missing).

This situation slightly reminds me of the interview process at some tech companies. Over the past year, I have interviewed on-site at 10 different companies. Two of those companies had one interview where the questions were extremely difficult and uncommon. When I told my friends those questions, many also thought the questions were bad interview questions.

It is important in any selection mechanism, like interviews, that we have a fair and consistent method of selecting applicants. Yet the questions need to be varied enough so that candidates cannot cheat by hearing the questions ahead of time.

> But statically typed languages really shine for maintenance and refactoring.

Possibly, I've not been able to find any research related to the impact of the typing discipline on maintenance.

All there is out there are studies on defect count of large code base projects. And those showed only marginal differences, certain dynamic languages like Clojure even beat out all others.

So at least in terms of maintening quality over time, dynamic languages seem to hold up to static languages.

What I've been trying to get data on is productivity over time. I know dynamic languages are more productive at the beginning, but do static languages get more productive over time is a good question. I still feel probably not, I think it's still just all a big feeling, but I've got no data on it.

Sorry, I was not saying that the article applied Chebyshev's inequality. It's not related at all. But it's an example of a result where you do not have to assume that your distribution is a member of a particular family of distributions. The result being applied here is really really general: it says that 95% of the probability mass occurs before the point at which 95% of the probability mass has occurred by. This is tautological. Like saying that 50% of people are below the median - it's true without making any assumptions about people (except that there are finite numbers of them).
I bought a Chromebook two years ago thinking I could wipe out Chrome OS completely and install Ubuntu to use as my primary machine. But I actually was only able to "sort of" install linux using crouton. It was cool but kind of annoying, you had to press all these crazy button combinations to boot up in developer mode and then enter shell commands to bring up Ubuntu. Pretty neat, but I was left with so little storage space I wasn't able to install Android studio so I couldn't use it as my primary laptop. Sadly, I don't think chromebooks make for very good primary machines. However, I wrote this comment using a chromebook, so I obviously dig them even if they have a ways to go.
I find this a specious argument.

Firstly, you should be considering the effect and not the object. The Berlin Wall was just a wall. It was geo-politics that bought down the wall. That's what was being predicted.

These changes tend to happen on human timelines. So arguing that an 8-year old geo-political setup may change in the next 24 years would make sense. That's basically saying in the next generation or two. You can throw the statistics out.

The effects that could wipe out humanity is a relatively specific list. And they definitely don't occur in human timeframes. You can work probabilities off that list. You'll come up with a completely different answer.
It's almost as if we don't live in a meritocracy, but rather a self-selecting good old boys club.

"But as Gott points out, our Neanderthal ancestors were around for only 300,000 years, while Homo erectus survived for about 1.6 million. They were smarter than the animals around them, but from a longevity standpoint they were completely unremarkable. Why should we be any different? Why should we be special?"

Circular argument. Competition with us was a factor in neanderthals extinction.
Alternative conclusion (not sure if the reasoning is correct) is that people will reach longevity relatively soon so new people won't be born anymore.

Anyway, it's really fascinating if you think about this. We're living in possibly the most unique and interesting century in the 200k year history of mankind - and even in the 4B years history of life - what are the chances of that? We're near the peak rate of technological progress.

What we consider normal, constant technological and societal progress is unique in the big picture, it can't continue forever and will stabilize in a few thousands years. After that, there will be long periods of stability and little change. The year 738,842 won't be dramatically different from 1,738,938.

Thanks for putting this to words. Now that you mention it, it is incredibly annoying, though the content was really interesting. I looked for an 'x' button on the banners more than once but then gave up and continued plowing through.

What is interesting is that I didn't get anywhere near the thought of commenting on this (or opening the chrome debugger or something to turn it off manually). So it's interesting that such visual noise can be a low-level annoyance without becoming a conscious thought. (Until your comment.)

I grew up in the 90s and wondered why every single Russian person I knew was Jewish. The wikipedia link is interesting. [1]

One non-Jewish person claimed there was no anti-Semitism. Everyone wanted to escape the Soviet Union and people just resented Russian jews because it was easier for them to leave. So I thought maybe anti-Semitism is so engrained that they didn't even notice it. Kind of like how some white Americans don't believe racism exists.

I have to work, but I don't know where would I fit. I am 41 and damaged mentally with this burn out or whatever this is. Any chance of getting a low stress job or am I too old and screwed?

Why isn't Apple Pay taking off?
This is all true. The way I think about it is this would be just like any other 51% attack, except that the motivation is specifically to compete by killing the former network. But game theoretically, it's still an attack, not a valid way to achieve consensus. So, as you say, the correct response is for the original network to hard fork.

To be clear, I'm not saying 2X is itself an attack (IMO, awfully close to crossing the line, though). I'm assuming that in your scenario, some mining faction is spending part of its compute on running 2X, and part on explicitly 51% attacking the original network.

That's certainly a metric that Bitcoin advocates would have been happy with, say, 5 years ago. Then they were agitating for major retailers to accept it as the obvious coming thing.

The fact that new major merchants are not joining and old merchants are going to the trouble of taking it out is a sign that earlier vision was flawed.
