But ChatGPT doesn’t have a way of “knowing” that there is no such Flatpak - it’s unlikely that its training data includes someone explicitly saying that. But it’s fair to “assume” that a Linux file manager is available as a Flatpak.
(…), so it’s definitely making up stuff.
Yes, it’s an LLM
Honestly, this is not really technobabble. If you imagine a user with a poor grasp of namespaces following a few different poorly written guides, then this question seems plausible and makes sense.
The situation would be something like this: the user wants to look at the container’s “root” filesystem (maybe they even want to change files in the container by mounting the image and navigating there with a file manager, not realizing that this won’t work). So they follow a guide to mount a container image into the current namespace, and successfully mount the image.
For the file explorer, they use pcmanfm, and for some reason decided to install it through Flatpak - maybe they use an immutable distro (containers on Steam Deck?). They gave it full filesystem access (with user privileges, of course), because that makes sense for a file explorer. But they started it before mounting the container image, so it won’t see new mounts created after it was started.
So now they have the container image mounted, have successfully navigated to the directory into which they mounted it, and pcmanfm shows an empty folder. Add a slight confusion about the purpose of xdg-open (it does sound like something that opens files, right?), and you get the question you made up.
Virtual memory isn’t swap, it is a mechanism that allows the operating system to give processes a view of memory that is almost completely decoupled from real physical memory and other processes. For example some programs require their code and data to be placed at exact memory locations in order to work - virtual memory allows you to run as many of these programs as you wish, because one process’s address 0x1000 has nothing to do with another one’s 0x1000, unless they set it up as shared memory (but even the same chunk of shared memory might be mapped to different addresses in the processes that share it).
Swapping is a cool trick that you can do with virtual memory, though. Basically you store a piece of memory somewhere outside the physical memory, and then make the address invalid in virtual memory. When the process tries to access it, it will crash. The OS will be notified of the crash, see that it was due to the process trying to access swapped out memory, load the chunk back from disk (maybe to a different physical location), update the virtual memory to correctly point to this chunk, and restart the crashed process from the instruction that caused the crash. So from the point of view of the process, nothing went wrong at all, except that one instruction took a very long time to execute.
Also, isn’t it harmful to SSDs?
Swapping doesn’t do enough writes to matter, unless your system is running really low on RAM.
xfwm is XFCE’s window manager, and it’s eating almost 30% of the total system memory, so that’s the prime suspect (I’m not exactly sure how much it interacts with other apps, so it’s possible something else is forcing xfwm to use all that memory, but that is IMHO unlikely).
An ugly “fix” is to log out and log back in (yes, not much better than just rebooting), or you could try to somehow restart xfwm - running xfvm --replace in terminal might work.
Edit: there’s an issue on the Manjaro forums that might be related: https://forum.manjaro.org/t/xfwm4-memory-leak-since-4-20/173910/7
That was my deleted comment, but then I realized the article specifies they are Rome CPUs (Zen 2), while the 4000 series of EPYCs is based on Zen 4

I don’t think overheating would cause random corruptions (it should throttle down when overheating, and then shut down if the temperature gets too high even when throttled, but there should never be an incorrect result of any computation), and surely the RAM will run at the standard 2133 speed on default settings - OP says they reset the BIOS settings to default between CPU swaps.
A simple rm -rf says hello
Google Maps is US-based whether you use it in the US or anywhere else
Sure, but I don’t see how any of that disproves the current “M$ supremacy” for “normies” - the fact is that people who couldn’t care less about how their computers work will have a much easier time using Windows (and probably macOS) than any Linux distro. You don’t have to worry that some software won’t be available to you because of your choice of the OS, and if you ever have a problem it’s easy to find help.
I haven’t used Windows in a decade on my personal computers, but as long as these two things hold true, it will always be my recommended OS for people who simply don’t care - I’m not going to spend my time doing free IT support for everyone I know and then get blamed everytime something doesn’t work.
Annoying warning keeps showing up at boot -> bring the PC to the nearest computer-literate person, and they’ll fix it. Good luck doing the same if you use Linux.
Obviously you need some redundancy in case the script gets corrupted. 5000 repetitions seems reasonable for such a high quality work
Yeah, stock Google voice recognition also works offline if you download the language model beforehand.
Indeed, try switching your smartphone to airplane mode and see how far your voice commands get you.
Did that (or rather disabled mobile data and WiFi, because airplane mode would still keep the WiFi on), and then I dictated this sentence after the parentheses. So Google’s voice input works offline just fine.
Or do they mean something like a smart assistant? In that case fair, but it’s not like it will work with text input either.
It is true, however, that Google Translate doesn’t do offline voice translation even if the language you’re trying to translate from is downloaded for system-wide voice recognition.
Don’t be ridiculous - this is a lab environment, they can faithfully recreate the suffering as long as the ethics committee doesn’t get notified.
That’s a reasonable per-core size, and it doesn’t make much sense to add all the cores up if your goal is to fit your data within L2 (like in the article)

That’s more of a storage thing, RAM does a lot smaller transfers - for example a DDR5 memory has two independent 32bit (4 byte) channels with a minimum of 16 transfers in a single “operation”, so it does 64 bytes at once (or more). And CPUs don’t waste memory bandwidth than transferring more than absolutely necessary, as memory is often the bottleneck even without writing full pages.
The page size is relevant for memory protection (where the CPU will stop the program execution and give control back to the operating system if said program tries to do something it’s not allowed to do with the memory) and virtual memory (which is part of the same thing, but they are two theoretically independent concepts). The operating system needs to make a table describing what memory the program has what kind of access to, and with bigger pages the table can be much smaller (at the cost of wasting space if the program needs only a little bit of memory of a given kind).
There’s no inherent guarantee that a router has a firewall configured properly, or has it enabled.
If it’s not an enterprise router (where you sometimes start with a blank configuration), it most definitely does have a firewall blocking incoming traffic by default.
In the deployments you’re seeing, are ISPs handing out /120 blocks to each router?
/120 is not enough for IPv6 to reasonably work. It kinda requires the smallest block to be /64, otherwise half the cool stuff about IPv6 breaks. So you should get something between /48 and /64 (the recommendation for ISPs is /56 for residential users so they can subdivide their network to 256 other networks, and /48 as default commercial allocation).
Does that require the ISP to have access to alter your home router, or do customers configure the DHCP themselves (which seems unlikely to scale)?
There is DHCPv6, but it’s not really an important part of a network like DHCP for v4 networks. IIRC Android doesn’t even support it. IPv6 uses Router Advertisement (RA) to tell devices what prefix they’re in (and a few things that were originally DHCP options, like the preferred DNS servers), and the devices then pick their own address using the SLAAC mechanism (originally it was derived from the MAC address, but nowadays should be a random number). RA supports “multilayer” networks where each following router further subdivides the prefix it got.
If you want a static address (for example for a server), you can either configure it manually on the device (using tokenized addresses, i.e. “static local part with dynamic prefix”), or use a DHCPv6 server to assign the address (in which case the RA responses from your router need to indicate that there is a DHCPv6 server on the network).
Also, you talked about the fc00::/7 (or its locally managed half, fd00::/8) prefix as a proof that NAT is used with IPv6, but… There’s absolutely nothing stopping you from having both a globally routable address and a local only address at the same time. IPv6 already requires you to have at least two addresses when you connect to any network - a link local address and whatever other address you get assigned (btw IPv4 never prevented you from doing the same thing, it just wasn’t directly encouraged and wasn’t widely used, and DHCP didn’t support handing out multiple addresses unlike RA).
You can even get a security “improvement” over the claimed scenario with NAT with this - if you don’t assign a global address to a node, then not only will it be unreachable from the internet, it will also be unable to connect to the internet itself while being reachable from your network without any issues. “Air gapping” (I know, I know… but people use this term for “no internet” now) for folks afraid of firewalls!
