Hard to achieve memory efficiency in Kubernetes clusters?

Hard to achieve memory efficiency in Kubernetes clusters? - Lemmy.World

When setting resources on Kubernetes pods, I’m finding it very difficult to achieve good memory efficiency. I’m using the “no CPU limits, set memory=limits” philosophy that I hear heavily recommended on the internet. The problem is, that many pods will have random memory spikes. In order for them not to be OOM Killed, you have to set the memory requests for them above their highest spike, which means most of the time they’re only using like 25% or so of their memory allocation. I’ve been trying to optimize this one cluster, and on average I’m only getting 33% of the total memory requested for all the pods in the cluster actually being used. Whenever I try decreasing some pod’s memory requests, I eventually get OOMs. I was hoping I could reach closer to 50%, considering that this particular cluster has a stable workload. I’m sure that I could optimize it a bit better, but not by much. Is this a shared experience in Kubernetes? That you ultimately have to sacrifice a lot of memory efficiency.

Would you host apps in Kubernetes even if they don't make full use of it, just to use a consistent set of devops tools?

Would you host apps in Kubernetes even if they don't make full use of it, just to use a consistent set of devops tools? - Lemmy.World

Hi all, I’m on a team right now that is converting a lot of apps that are running on ec2 over to eks, and we’re starting with apps that make the most sense for eks. Apps like LGTM stack which have lots of distributed components, Airflow, etc. We’re setting up flux and renovate which really streamlines maintenance, and I like it so much that I’m wondering about converting apps that aren’t particularly well suited for kubernetes over to eks just to use the same toolset. We have some apps on ec2 that are essentially just a single docker container, they can be run in parallel but they don’t have to talk to each other. Some of these apps don’t require many resources, so the $70 / month control plane cost of EKS is significant, which I imagine is the biggest reason we wouldn’t convert over. Just curious what thoughts are on this.

How to make sauces less potent so you can douse your food in them?

How to make sauces less potent so you can douse your food in them? - Lemmy.World

I love food that is doused in sauce. Especially Mexican food (like tacos or burritos) and Asian food (like stir fries) where everything is drenched. The problem is, that a lot of the base ingredients in sauces are pretty potent. Like soy sauce or most hot sauces, if you “drenched” your food in it, it’d be too strong. So what’s the secret? Do you basically just add a bunch of water to it?

Anyone automate anything with smart thermostats and outdoor temp?

Anyone automate anything with smart thermostats and outdoor temp? - Lemmy.World

I have a pretty simple smart thermostat without many fancy features. Every Spring and Fall I tell myself I should set up some kind of system where if the outdoor weather is good enough, maybe I dial back the heating / cooling, maybe send myself a text to open windows, etc. Small example: I normally keep my house at 72 in the summer, but if it’s up to 76 or so outside, it’d be nice if the thermostat turned off the cooling. I could manually turn it back on if I have guests over, etc. I’m sure some of this logic would be easy to code myself, but wanted to check out what anyone else is doing first. Using home assistant.

What external services do you use for your selfhosting setup?

What external services do you use for your selfhosting setup? - Lemmy.World

I mean anything that is not hosted in your house. For example, dynamic dns, some type of ddos protection, off-site backups, external oauth provider, etc.

I’ve reported the SNAP to Canonical and emailed KDE security.

It looks like this exact same thing happened a year and a half ago (just search “snap exodus scam”).

My dad just got scammed a lot of money by downloading this fake Exodus cryptocurrency wallet from the Discover app. I really can’t blame him too much, it looks legit and usually you don’t think of getting scammed in the official Discover app.

[Bass] Ideas for playing in public without amplification?

[Bass] Ideas for playing in public without amplification? - Lemmy.World

Hi /c/guitars, I’m a bassist (there’s not really a good community for bassists on Lemmy yet), and something I’ve been wanting to do for a while now is do an acoustic-y jam at a public park with friends. The problem is, most cities draw the line at amplification. It’s a bit annoying because an unamplified drum set can be crazy loud and that’s okay, but a slightly amplified bass will get you in trouble. The way I think of it, I have 3 options (1) Unamplified acoustic bass. The problem is, these are just not that loud. (2) Secretly amplified acoustic bass? Hear me out. I was thinking if I got a small battery powered amp, and hid it in a backpack, and only had it slightly on, it might not get noticed. I would only need a slight boost (3) Get a really cheap double bass? I’ve always wanted a double bass, but those things are crazy expensive. There are technically ones for like $1k or under, but everyone says to stay away because they are pieces of crap. Maybe that’s what I’m looking for though? I don’t think I’d want to bring a nice $6000 upright bass to a public park… Anyway, just curious what thoughts anyone has, especially anyone who has done this before in a big city.
