For those who find it interesting, enjoy!
I really enjoy your transparency and style of communication!
Comparing it to Spez and how Reddit became prior to the migration, this is such a refreshing change
/u/Ruud is like /u/Spez but only if /u/Spez was actually cool.
It gets me every time seeing people using the product I build 🥹
You worked on Grafana? Your product is awesome, I use it in my homelab for performance metrics
Yes, I’m one of the designers 👍🏾

Poggers. Couldn‘t live wuthout it. Thank you for your work!
That’s so cool! Grafana is awesome, the whole team did a great job
Love Grafana, especially the new UI. Great work, man. :)
Grafana is one of those tools which everyone should use if they have something they maintain themselves. Superb tool.
Thank you very much.
Do you work on Loci too?
You work at Grafana?
It’s been very snappy today, nice work! Is it all under Docker Compose with the node handling Nginx and Postgres as well?
Yes.
Why did you guys roll back the UI to .7 from .10? I enjoyed some of the UI improvements, but I guess there were some bugs?
Edit: I see its back to .10 maybe I had a browser tab open from before that I never refreshed
I‘m really grateful for your and your colleagues‘ work. Thank you for letting us lemmy around here!!!
I can’t believe how fast you’ve managed to crowdsource and fix things on this instance. I haven’t seen many problems at all sharing comments and things.
Dang that’s a lot of RAM
mastodon.world has the same server but with twice the RAM :-)
What chassis? I’ve got 256GB in an R720 but only 32 cores here!
It’s a AX161 server at Hetzner
€142 is more reasonable than I expected! I’ll toss some cash to help!
How can I throw some bucks in your direction?

Edit: thank you all!
It’s on the right-hand sidebar of lemmy.world:
Awesome! I’m on mobile, so I cannot see it. Will check it out when I get to my computer.
You can view sidebar on mobile. I think it’s in the three dots, but it’s somewhere!
EDIT: On Jerboa it’s under Community Info, under the three dots. On the mobile web app for L.W. there’s a sidebar button.
Just go to lemmy.world and click sidebar.
This is awesome! As a systems engineer for my day job, I love seeing stuff like this!
Some of my usage is in this data and I like that.
pretty gauges. the instance seems to be more stable/responsive today
31.2% load it’s damn fine considering how much attention Lemmy.world has been getting lately. Server is up for 3 weeks already so I guess that’s when you upgraded it?
How much is that in beans?
At least 1
Possibly 2
Let’s not go crazy
About tree fiddy
How much is this costing you? Also who is your host? Is it on a virtual machine?
They have a dedicated server: https://lemmy.world/post/75556
It’s actually pretty funny to see him mention the growth (almost 12k users!) considering they’ve added, what, 50k or so users recently?
Whoa, cool. Thanks. Only a matter of time until it gets overloaded though. Can’t Lemmy run in a container service like Cloud Run or AWS App Runner?
Dedicated means local?
No, it means it’s got the physical machine all to itself. It’s a rented server located in a Hetzner data center.
Damn that’s a huge chunk of (what looks like) a 64 core CPU there. Impressive!
It’s cool it can aggressively cache that much. Although I am perplexed why one would have a swap file configured in this case? What does it give you here? Sorry not trying to be an elitist or anything just have no idea what advantage you get!
To be honest I tend to use swap less and less. But this was in the build that Hetzner does and I didn’t remove it.
If your application goes wild with RAM usage, a properly configured swap will make sure the underlying OS remains responsive enough to deal with it.
The OOM killer is usually triggered after it starts hitting the disk. Which means your system is unresponsive for a long time until it finally kills something.
Using something like oomd can help trigger before it hits swap but then why are you using swap in the first place?
The bigger issue is that the kernel sometimes ignores the swappiness and will evict code/data pages long before file cache even when set to 0 or 1. I’m still not sure if that was because of an Ubuntu patch or if it was an issue that’s been resolved in the years since I last saw this
I know that the RAM cache is just taking advantage of otherwise free RAM and will be dropped in favor of anything else, but it does stress me out a bit to see it “full” like that.
It would stress me even more to see a lot of RAM doing nothing, that would be a shame! ;-)
Difference between Windows and Linux. Windows would only use what it needs. Linux pre-empts more and fills the RAM for what coul dbe needed.
It used to stress the shit out of me when I switched to Linux as I’d gotten used to opening task manager and seeing 90% free RAM. On Linux I’d be seeing 10% free and panicking thinking it was a resource hog.
The Linux-way is the best way.
I use Arch btw ;)
Both OSes do pre-caching and for both the standard tools to check usage nowadays ignore pre-cached elements when counting RAM usage.
I had a feeling that ‘factoid’ may be out of date! Since I learnt it about the time of Windows XP when we were shown examples of how Linux and Windows memory management differed. It all made sense why Linux seemed to have full RAM even after a big upgrade but WinXP gave the ‘illusion’ of having lots of free RAM to use. ~ 20yrs ago!
I think we used SuSE Linux 7.3!
I still hold a savage hatred of all RPM-based distros after dealing with the hell of early 2000’s editions (Redhat, Mandrake & Suse). Though I did like SuSE KDE’s colours when it worked!
It’s free real estate!
If you had this much buffer memory what are the reasons to have swap space as well?
With my servers I’m paranoid having swap enabled will inadvertently slow stuff down. Perhaps there’s a reason to have it that I’m unaware of?
If you had this much buffer memory what are the reasons to have swap space as well?
Many programs do stuff once during startup that they never do again, sometimes creating redundant data objects that will never get accessed in the configuration its being run in. Eventually the kernel memory manager figures out that some pages are never used but it can’t just delete them. If swap is enabled it can swap them to disk instead. It frees up that RAM for something more important. It’s usually minor but every few MB helps.
