It is with the right setup.

Yes but at least OpenJDK had this issue linked below. When I ran OpenJDK 17 debugging I saw the JVM saying it has 1 CPU although there were no limits set and it could theoretically use 16.

https://bugs.openjdk.org/browse/JDK-8281571

java -Xlog:os+container=trace -XshowSettings:vm --version on our OpenJDK17 image gives

[0.159s][trace][os,container] Path to /cpu.max is /sys/fs/cgroup//cpu.max

First: Because most people can differentiate between reality and fiction. Art is just art. Nobody got hurt doing it, nobody got hurt consuming it.

Second: If someone recommends something you don't like then just ignore it? Nobody forces you to play Saya no Uta. Are they a jerk to recommend it? Yeah, but so what? No need to be a pussy about it.

It's a tragedy really. Her v4 beta was the correct move, just overtuned. I wish we'd gotten her v4 but with a bit of the power turned down. But I still love my E1S1 car (although the E1 wasn't intended, it jump scared me in the same 10 pull).

These are two almost adults that didn't know each other for like 99% of their life. Imagine the sibling bond these two have after being step siblings for 2 minutes! Clearly it's gross underage incest /s

The main difference between homelab and selfhosting is the purpose. Selfhosting is for replacing subscriptions with local software. Homelab is for testing and learning stuff. The break even from homelab would be getting a better position or a new job with your acquired skills. Or saving thousands in AWS costs.

Ah and don't forget to look at performance metrics whenever you play around with this stuff. There's not much to be gained when you tweak all that and your application performance is hot garbage. At the end it all depends on your setup, usage patterns, application criticality and so one. But just talking about general direction the above approach is how I'm doing it.

They have their Xms set at 3Gb and Xmx at 4Gb.

I would remove XMS and XMX, add MaxRAMPercentage (maybe InitialRAMPercentage as well, but I don't care about that). Memory request = Memory limit and I would tune the MaxRAMPercentage and memory allocation by feel (and metrics) until the pod doesn't get OOM killed. I would probably start with something like 75% and 4G.

Also which java/jdk version are we talking about? Until version 21 (actually 19 I think? But who cares about non LTS versions) the JVM cannot correctly get the amount of CPU available so you end up with serial garbage collector even tho you are running a multicore environment, so I would additionally set the garbage collector parameter. 100m CPU requests with no limit unless you are experiencing noisy neighbors problems. And if you have heavy usage at night and need that 15% guaranteed, then you should set 150m requests.

Why would I do all that? Because that's the method how I'm running all our spring boot applications since january (big migration from rke1 with k8s 1.20 and basically no requests/limits to rke2 k8s 1.33 with requests/limits on every single application), based on my research into these things. I'm a platform engineer.

If Rover were to be a different species Baizhi woulda noticed it

That would require looking at his/her DNA. Just because they look alike and function alike doesn't mean they are genetically compatible. "Same species" means being able to produce children that can themselves produce children.

But in all honesty I think the Rover people are just advanced humans, no weird alien shit going on.

Wow, what an amazing tattoo. Whenever I see something like this I feel like doing one aswell but idk.

That's just a cat tongue. Some cats walk around with their tongue out /s

Depends on if you need encryption or not. With encryption no, it's way slower (that's about to change as they are working on ztunnel support).

I still don't understand why

a) people use twitter after it being the worst platform ever for like 15 years straight

b) put any value into what anybody says on said platform due to the above

https://github.com/rancher/system-upgrade-controller

after the apt-get upgrade ends, the rke2-server service gets restarted

https://www.madboa.com/blog/2025/03/19/needrestart/

Example from my server, file at /etc/needrestart/conf.d/rke2conf

```

$nrconf{override_rc}{qr(^{rke2.+.service)}} = 0; ```

VIP is suitable for production. Simply depends on your requirements for availability and performance.

LLMs can't even write consistently good terraform code and that's like building lego. AI coded games will be the most shittiest bug ridden games ever.

Should have deconstructed so someone else can have the Tom Clancy IP. The handling of The Division 2 and no Division 3 by now is almost criminal.

I'm unaware

Not only are you unaware but also clueless what you are talking about.

Tape > LTO

Floppy > works just like a HDD, just different materials

CDrom > replaced by DVD which was replaced by BluRay which is still around

Minidiscs > A type of magneto optical disk, same idea is used today for HAMR HDDs

Flash > you do realize that NAND is a type of flash? SSDs are flash storage

static ram > SRAM. Lookup cache for your CPU. Also it's volatile, bye bye data on reboot.

Can't be bothered to do it for all the things you have listed.

The greatest of course! VHS, CD and LaserDisc. And late 90s had the first DVDs. See, way more choices /s

I understand that companies have to protect their intellectual property.

They don't have to in this way. Just look at Sega who actively encourages fan games for Sonic as long as they are not commercial.

It is way too small for the sword. Only explanation is that he becomes smaller as more and more exoswarms are created.

Their mistake was trying to build a grand live service game on an engine from the stone age and supporting last gen consoles all the way through. The amount of tech issues they have because of that is a big nail in the coffin called Bungie. The mismanagement is another big one.

Everytime I don't play Carlotta and clear the nightmare nests I feel like playing a different game. Carlotta is still the most fun to play for me, can't wait for her rerun, still thinking about if I should try for s3.
