We are talking about addresses, not counters. An inherently hierarchical one at that. If you don’t use the bits you are actually wasting them.

Bullshit.

I have a 64-bit computer, it can address up to 18.4 exabytes, but my computer only has 32GB, so I will never use the vast majority that address space. Am I “wasting” it?

All the 128 bits are used in IPv6. ;)

Yes they are all “used” but you don’t need them. We are not using 2^128 ip addresses in the world. In your own terminology: you are using 4 registers for a 2 register problem. That is much more wasteful in terms of hardware than using 40 bits to represent an ip address and wasting 24 bits.

you are wasting 24 bits of a 64-bit register

You’re not “wasting” them if you just don’t need the extra bits, Are you wasting a 32-bit integer if your program only ever counts up to 1000000?

Even so when you do start to need them, you can gradually make the other bits available in the form of more octets. Like you can just define it as a.b.c.d.e = 0.a.b.c.d.e = 0.0.a.b.c.d.e = 0.0.0.a.b.c.d.e

Recall that IPv6 came out just a year before the Nintendo 64

If you’re worried about wasting registers it makes even less sense to switch from a 32-bit addressing space to a 128-bit one in one go.

Anyway, your explanation is a perfect example of “second system effect” at work. You get all caught up in the mistakes of the first system, in casu the lack of addressing bits, and then you go all out to correct those mistakes for your second system, giving it all the bits humanity could ever need before the heat death of the universe, while ignoring the real world implications of your choices. And now you are surprised that nobody wants to use your 128-bit abomination.

Hmm, I can’t say that I’ve ever noticed this. I have a 3950x 16-core CPU and I often do video re-encoding with ffmpeg on all cores, and occasionally compile software on all cores too. I don’t notice it in the GUI’s responsiveness at all.

Are you absolutely sure it’s not I/O related? A compile is usually doing a lot of random IO as well. What kind of drive are you running this on? Is it the same drive as your home directory is on?

Way back when I still had a much weaker 4-core CPU I had issues with window and mouse lagging when running certain heavy jobs as well, and it turned out that using ionice helped me a lot more than using nice.

I also remember that fairly recently there was a KDE/plasma stutter bug due to it reading from ~/.cache constantly. Brodie Robertson talked about it: https://www.youtube.com/watch?v=sCoioLCT5_o

IPv6 = second system effect. It’s way too complicated for what was needed and this complexity hinders its adoption. We don’t need 100 ip addresses for every atom on the earth’s surface and we never will.

They should have just added an octet to IPv4 and be done with it.

At 17:00 everyone’s got a beer on their desk and by 18:00 the doors are locked and the lights are out. One Thursday a month the table is used for beer pong after work and we play card games like Exploding Kittens.

I’d rather go home at 17:00 and do all those things with my real friends, or you know, spend some quality time with my partner.

You don’t even have to NAT the fuck out of your network. NAT is usually only needed in one place: where your internal network meets the outside world, and it provides a clean separation between the two as well, which I like.

For most internal networks there really are no advantages to moving to IPv6 other than bragging rights.

The more I think about it, the more I find IPv6 a huge overly complicated mistake. For the issue they wanted to solve, worldwide public IP shortage, they could have just added an octet to IPv4 to multiply the number of available addresses with 256 and called it a day. Not every square cm of the planet needs a public IP.

It’s when you have to set static routes and such.

For example I have a couple of locations tied together with a Wireguard site-to-site VPN, each with several subnets. I had to write wg config files and set static routes with hardcoded subnets and IP addresses. Writing the wg config files and getting it working was already a bit daunting with IPv4, because I was also wrapping my head around wireguard concepts at the same time. It would have been so much worse to debug with IPv6 unreadable subnet names.

Network ACLs and firewall rules are another thing where you have to work with raw IPv6 addresses. For example: let’s say you have a Samba share or proxy server that you only want to be accessible from one specific subnet, you have to use IPv6 addresses. You can’t solve that with DNS names.

Anyway my point is: the idea that you can simply avoid IPv6’s complexity by using DNS names is just wrong.

You do need to know it when you’re working with subnets and routing tables.

Unless you have anything but a flat network structure with everything in one subnet, working with IPV6 is a giant PITA.

It’s a documentary.

Yeah god forbid people have some interesting discussion on this platform, right?

The post doesn’t answer the questions, it’s why I asked.

It says:

All running on a krun microVM with FEX and full TSO support 💪

I was not expecting Party Animals to run! That’s a DX11 game, running with the classic WineD3D on our OpenGL 4.6 driver!

Now I know some of these words, but it does not answer my question.

So how does that work given that most Steam games are x86/x64 and the M2 is an ARM processor? Does it emulate an x86 CPU? Isn’t that slow, given that it’s an entirely different architecture, or is there some kind of secret sauce?

I ran it perfectly on a 33MHz 486 with 4mb RAM for a long time. Even Doom II with some of its heavier maps ran fine.

“Perfectly” would mean it ran at 35fps, the maximum framerate DOS Doom is capped at. In the standard Doom benchmark, a dx33 gets about half that: 18fps average in demo3 of the shareware version with the window size reduced 1 step. Demo3 runs on E1M7, which isn’t the heaviest map, so heavier maps would bog the dx33 down even more.

I’m sure you found that acceptable at the time, and that you look back on it with slightly rose-tinted glasses of nostalgia, but a dx2/66 and preferably even better definitely gave you a much better experience, which was my point.

If anyone can enlighten me, This is pretty much why you can find DooM on almost any platform BECAUSE of its Linux code port roots?

I mean yeah. Doom was extremely popular and had a huge cultural impact in the 90s. It was also the first game of that magnitude of which the source was freely released. So naturally people tried to port it to everything, and “but can it run Doom?” became a meme on its own.

It also helps that the system requirements are very modest by today’s standards.

It ran like absolute ass on 386 hardware though, and it required at least 4MB of RAM which was also not so common for 386 computers. Source: I had a 386 at the time, couldn’t play Doom until I got a Pentium a few years later.

Even on lower clocked 486 hardware it wasn’t that great. IIRC, it needed about a 486 DX2/66 to really start to shine.

What has Rocky done?

Also, I 100% understand not liking Oracle as a company, but anyone can use OEL freely without ever having to deal with Oracle the company, and it’s a damn good RHEL substitute.

Without knowing what was being hosted, the only surefire way would be pulling a complete disk image with cat or dd.

That’s not surefire, unless you’re doing it offline. If the data is in motion (like a database that’s being updated), you will end up with an inconsistent or corrupt backup.

Surefire in that case would be something like an lvm snapshot.

If you wanted to stay on a similar system, RHEL 9 would be a good option or one of its “as similar as possible” like AlmaLinux.

No love for Rocky?

Also Oracle Linux is still free, and fully compatible with RHEL.

How the fuck am I supposed to know that Network Manager won’t support DNS over TLS

Read the documentation? Use google?

The very first hit when you google “dns over tls tumbleweed” provides the answer: https://dev.to/archerallstars/using-dns-over-tls-on-opensuse-linux-in-4-easy-steps-enable-cloud-firewall-for-free-today-2job

A more generic query “dns over tls linux” gives this, which works just the same: https://medium.com/@jawadalkassim/enable-dns-over-tls-in-linux-using-systemd-b03e44448c1c

Both google searches return several more hits that basically say the same thing.

Even the NetworkManager reference manual refers you to systemd-resolved as the solution: https://www.networkmanager.dev/docs/api/latest/settings-connection.html

I don’t use NetworkManager, I’ve never even used Tumbleweed and I found the answer in all of 10 minutes. Of course that doesn’t help if you’re so clueless that you didn’t even know that you were using DNS-over-TLS, or that DoT is a very recent development that differs significantly from regular DNS and that it requires a DNS resolver that supports it.

when every other operating system does?

Like Windows 10? (Hint: it doesn’t)

You use Arch. Mr skillful

Who cares what I use. When I’m messing with something I don’t understand, I at least read the documentation first instead of complaining on the internet and calling the whole community toxic and, I quote, “Butthurt Linux gobblers” when you get the slightest bit of pushback.
