Schengen has independent of the EU status. Eg. you can move freely from Germany to Switzerland (without obligatory border check) but not between Germany and EU-member Cyprus (there is the obligatory border check).
> but its rarely gb at the same time. Thats the point. Its a dumping ground for stuff thats not used very often.
But it has to be GB to actually make a difference. If your swap is not full of GB of data, then obviously you don't need it (or it just becomes a reserve when you are in an OOM situation - but this is where you don't want to be with swap avaible either)
> What if I don't have no more free DIMM slots but I already have 1 TiB NVMe and I am fine with my workload being finished slightly (or even noticeably) slower as opposed to not being able to do at all?
Then you obviously have a workload where having swap make sense (and you could even add swap on the fly in such a case). But that is not typical at all.
> Given that the author works at a large company, that has millions of machines, and where any swap change has cost implications in the tens of millions pounds, I suspect the article is based on data, rather than vibes.
Yes, but the author is most likely optimizing for a metric that I don't care so much in my per personal computer while dismissing metrics that I care about.
> It was always the case. but then a TB of disk isn't that expensive anymore.
But swapping out GB of RAM is expensive in terms of latency.
> Swapping 32GB of memory in and out of an NVMe SSD is much faster than swapping 1GB out of a spinning disk so I really don't get that argument.
This is true, but it still takes time. What kind of workload do you have where you swap out 32GB of RAM? If you are in this situation you almost certainly need to buy these additional 32GB of RAM.
This reads like something from the 90s. Buy whatever you think you need as swap as "more RAM" and call it a day. I'm running my desktop Linux without swap since maybe 20 years, and I never had any of this "pathological behaviour at near-OOM" afterwards.
And I have time to think about better problems than "You can achieve better swap behaviour under memory pressure and prevent thrashing by utilising memory.low and friends in cgroup v2."
The core problem with swap is that nowadays you need gigabytes of swap to actually make a difference (when you have 32GB of RAM, 1GB of swap is 1/32 of a difference). And you certainly don't want to system to swap in and out gigabytes of memory.
What I wrote was a bit unclear: They want to avoid that you buy a low cost ticket and resell it to somebody else a day before the flight (because you either cannot make it or because you want to make money).
The "your username/password is wrong" message came in a timely manner. So someone transformed "some unforeseen error" into a clear but wrong error message.
And this caused a lot of extra trouble on top of the incident.
> That said, getting there strikes me as pretty challenging. Automatically detecting a down state is difficult and any detection is inevitably both error-prone and only works for things people have thought of to check for. The more complex the systems in question, the greater the odds of things going haywire. At Meta's scale, that is likely to be nearly a daily event.
Well, in principle, the frontend just has to distinguish between HTTP status 500 (something broken in the backend, not the fault of the user) and some HTTP status code 4xx (the user did something wrong).
The EU is showning these banners on their own websites. So not even the EU is capable of creating a website without banners (because - even the EU - wants analytics and other bullshit).
> And you clearly want to carry 3000+ EUR in your pocket than paying by card? Europe is safe, but I will definitely not walk around with that much cash on my person.
I'd also rather pay the Macbook by card due to practicality, but I don't understand your second sentence. Why would you walk around with a Macbook worth 3k but not with 3k in cash? Nobody knows that you have 3k in cash with you, whereas everybody can see you walking out of the Apple Store with the Macbook.
> Oh absolutely, you'd never want to run such a program. However, it's existence is a useful mathematical trick.
This was the beginning of the thread: If you have a non-constructive proof that P=NP, it still means you cannot solve all NP problems quickly until someone actually finds a program to do so.
yet 95% of the prison inmates are male. There are obvious differences on the extreme ends of the spectrum between males and females and the nobel price only considers extremes to begin with.
