Readit NewsI assumed they were switching to Rust, but that doesn't seem to be the case.
Similar technology exists for Rust, but it is much less advanced than SPARK is (https://github.com/xldenis/creusot)
"Welp, back to C because AMD's performance is overtaking ours."
> As you can see from the source files, that required adding many specifications (around 400 preconditions and 500 postconditions) and ghost code (around 150 loop invariants, 400 assertions, 300 ghost entities), and the daily proof takes 1.5 hours on a Linux server with 36 cores.
So 40 units with only a few hundred pre/post conditions and invariants seems to take an enormous amount of compute time to verify.
I expect that the verifier has already been fairly well optimized since Spark has been around awhile. Is this the case?
For verification in general, is the expense of verification in this case because of the model needed to verify Ada? For instance, perhaps a language that makes different choices might have a model checker that could scale better.
This has important implications for scaling formal methods to more software.
I don't think so. The SPARK subset has been chosen to aid verification. The problem of proof is inherently computationally hard, and the most gains you can expect will come from advances in solver technology, both algorithmic and in terms of scaling to multiple cores or GPU eventually.
Just my opinion :) But I work at AdaCore (not on SPARK) so have some familiarity with the subject.

So you have a workflow similar to cargo in Rust:
* Install package manager * Let package manager install toolchains * ??? * Profit
And frankly I'm sick of being lumped in to large generalizations of America that simply don't apply to me or millions of other people living here.
The media (including social media, and the internet) largely consists of the most divisive and stereotyped parts of life. America doesn't consist solely of highways and single family communities. There isn't just one "American lifestyle."
My first few times in the US were in NYC, where I found a way of life that is very close to what I know as a Parisian. Imagine my surprise discovering basically any other city in the US.
You might not be part of that population, but the US problem goes way beyond a problem of perception, and there are numbers to confirm it.
I'm not advocating for staying home; I'm advocating for less driving. It may not make as much of a difference in the E.U., but if we're aiming to be carbon neutral, less driving will be necessary, or, at least, extremely helpful in achieving that goal.
I guess what I'm getting at is that if people drive less, they'll realize that their car-centered lifestyles don't work anymore, and will have to find alternatives. Let's hope that's easier than what I envision :)
I'm pretty sure a large part of the reason why Americans are so lonely compared to the rest of the world is that the suburban bedroom community model physically divides us and makes it much more difficult to get to know one's neighbors. By the time you get home from work at 6:30 in the evening, it's time to cook dinner, and, once you're done cleaning up, there's not much time for anything aside from watching a bit of TV before you go to bed.
And then the weekend rolls around, and your time is dominated by catching up on all the housework and errands you didn't have time to do during the week because of your long commute. So you're not really getting to know your neighbors then, either.
I can indeed see a world where working from home might in the short term infuse some life in local life, from neighbors to associations etc.. So maybe it's actually a positive change!
That is maybe a bubble around the internet. Ime most programmers in my environment rarely use and certainly aren't dependent on it. They do also not only do code monkey-esque web programming so maybe this is sampling bias though it should be enough to refute this point.
