This is because there isn’t a job shortage. It’s offshoring. The company I (thankfully willingly) left 2 years ago has shifted all of their software hiring to Europe. And since I left has had multiple US focused layoffs. All while the Euro listings keep popping up. And I get it, the cost of living is much lower and the skill set is equivalent. So yea, get your bank. But, this is companies exploiting Europe/Asia, rather than it being something Europe/Asia is immune to.
Yea, it’s the combo of the chiller and cooling tower is analogous to a swamp cooler. The cooling tower provides the evaporative cooling. The difference is that rather than directly cooling the environment around the cooling tower, the chiller allows indirect cooling of the DC via heat exchange. And isolated chiller providing heat exchange is why humidity inside the DC isn’t impacted by the evaporative cooling. And sure, humidity is different between hot and cold isles. That is just a function of temperature and relative humidity. But, no moisture is exchanged into the DC to cool the DC.
Edit: Turns out I’m a bit misinformed. Apparently in dry environments that can deal with the added moisture, DCs are built that indeed use simple direct evaporative cooling.
Practically all even semi-modern DCs are built for servers themselves to be air cooled. The air itself is cooled via a heat exchanger with a separate and isolated chiller and cooling tower. The isolated chiller is essentially the swamp cooler, but it’s isolated from the servers.
There are cases where servers are directly liquid cooled, but it’s mostly just the recent Nvidia GPUs and niche things like high-frequency-trading and crypto ASICs.
All this said… For the longest time I water cooled my home lab’s compute server because I thought it was necessary to reduce noise. But, with proper airflow and a good tower cooler, you can get basically just as quiet. All without the maintenance and risk of water, pumps, tubing, etc.
If you’re considering video transcoding, I’d give Intel a look. Quicksync is pretty well supported across all of the media platforms. I do think Jellyfin is on a much more modern ffmpeg than Plex, and it actually supports AMD. But, I don’t have any experience with that… Only Nvidia and Intel. You really don’t need a powerful CPU either. I’ve got my Plex server on a little i5 NUC, and it can do 4k transcodes no problem.
You really don’t need an AIO with a 5600X. Just grab a reasonably sized tower cooler and call it a day. There’s less to fail, and less risk of water damage if it fails catastrophically. I’ve found thermalright to be exceptionally good for how well priced they are. Not as quiet as Noctua, but damn near the same cooling performance.
Another thing to consider is that a 5600X doesn’t have built in graphics. I think you’d need to jump up to AM5/7600X for that.
A coworker of mine built an LLM powered FUSE filesystem as a very tongue-in-check response to the concept of letting AI do everything. It let the LLM generate responses to listing files in directories and reading contents of the files.
Honestly, I don’t mind them adding ads. They’ve got a business to support. But, calling them “quests” and treating them as “rewards” for their users is just so tone-deaf and disingenuous. Likewise, if I’ve boosted even a single server, I shouldn’t see this crap anywhere, let alone on the server I’ve boosted.
After repeated failures to pass a test, I do not think it is unreasonable for the business to stop paying for your attempts at a certification. Either directly via training sessions and testing fees, or indirectly via your working hours.
In the US, salaried engineers are exempt from overtime pay regulations. He is telling them to work 20 extra hours, with no extra pay.
Commentary from someone quite trusted in the historical gun community and who’s actually shot multiple Welrods/VP9s: https://www.youtube.com/shorts/POubd0SoCQ8
It’s not a VP9. Even at the very start of the video, on the first shot before the shooter even manually cycles the gun, gas is ejected backwards out of the action rather than forward out of the suppressor.
In general, on bare-metal, I mount below /mnt. For a long time, I just mounted in from pre-setup host mounts. But, I use Kubernetes, and you can directly specify a NFS mount. So, I eventually migrated everything to that as I made other updates. I don’t think it’s horrible to mount from the host, but if docker-compose supports directly defining an NFS volume, that’s one less thing to set up if you need to re-provision your docker host.
(quick edit) I don’t think docker compose reads and re-reads compose files. They’re read when you invoke docker compose but that’s it. So…
If you’re simply invoking docker compose to interact with things, then I’d say store the compose files where ever makes the most sense for your process. Maybe think about setting up a specific directory on your NFS share and mount that to your docker host(s). I would also consider version controlling your compose files. If you’re concerned about secrets, store them in encrypted env files. Something like SOPS can help with this.
As long as the user invoking docker compose can read the compose files, you’re good. When it comes to mounting data into containers from NFS… yes permissions will matter and it might be a pain as it depends on how flexible the container you’re using is in terms of user and filesystem permissions.
Docker’s documentation for supported backing filesystems for container filesystems.
In general, you should be considering your container root filesystems as completely ephemeral. But, you will generally want low latency and local. If you move most of your data to NFS, you can hopefully just keep a minimal local disk for images/containers.
As for your data volumes, it’s likely going to be very application specific. I’ve got Postgres databases running off remote NFS, that are totally happy. I don’t fully understand why Plex struggles to run it’s Database/Config dir from NFS. Disappointingly, I generally have to host it on a filesystem and disk local to my docker host.
In general, container root filesystems and the images backing them will not function on NFS. When deploying containers, you should be mounting data volumes into the containers rather than storing things on the container root filesystems. Hopefully you are already doing that, otherwise you’re going to need to manually copy data out of the containers. Personally, if all you’re talking about is 32 gigs max, I would just stop all of the containers, copy everything to the new NFS locations, and then re-create the containers to point at the new NFS locations.
All this said though, some applications really don’t like their data stored on NFS. I know Plex really doesn’t function well when it’s database is on NFS. But, the Plex media directories are fine to host from NFS.

Yea, I don’t think this is necessarily a horrible idea. It’s just that this doesn’t really provide any extra security, but even the first line of this blog is talking about security. This will absolutely provide privacy via pretty good traffic obfuscation, but you still need good security configuration of the exposed service.
If I understand this correctly, you’re still forwarding it a port from one network to another. It’s just in this case, instead of a port on the internet, it’s a port on the TOR network. Which is still just as open, but also a massive calling card for anyone trolling around the TOR network for things to hack.
This isn’t about social platforms or using the newest-hottest tech. It’s about following industry standard practices. You act like source control is such a pain in the ass and that it’s some huge burden. And that I just don’t understand. Getting started with git is so simple, and setting up an account with a repo host is a one time thing. I find it hard to believe that you don’t already have ssh keys set up too. What I find more controversial and concerning is your ho-hum opinion on automated testing, and your belief that “most software doesn’t do it”. You’re writing software that you expect people to not only run on their infra, but also expose to the public internet. Not only that, but it also needs to protect the traffic between the server on public infra and client on private infra. There is a much higher expectation of good practices being in place. And it is clear that you are willingly disregarding basic industry standard practices.
Github and Gitlab are free, and both even allow private repos for free at this point. Git is practically one of the first tools I install on a dev machine. Likewise, git is the defacto means of package management in golang. It’s so built in that module names are repo URLs.
I work at an Infrastructure Cloud company. I design and implement API and Database schemas, I plan out backend workflows and then implement the code to perform the incremental steps of each workflow. That’s lots of code, and a little openapi and other documentation. I dig into bugs or other incidents. That’s spent deep in Linux and Kubernetes environments. I hopefully build monitors or dashboards for better visibility into issues. That’s spent clicking around observability tooling, and then exporting things I want to keep into our gitops repo. Occasionally, I’ll update our internal WebUI for a new feature that needs to be exposed to internal users. That’s react and CSS coding. Our external facing UI and API is handled by a dedicated team.
When it comes to learning, Id say find a problem you have and try to build something to improve that problem. Building a home lab is a great way to give yourself lots of problems. Ultimately, it’s about being goal oriented in a way where your goal isn’t just “finish this class”.
