Some of the hardware sold under their name is/was quite ok.
I'm not sure who designed and created that stuff, though.

I'm laughing and close to crying, though I'm not sure whether from parallels to my work I get reminded of or from finding it hilarious.
I suppose it's a bit from both.
Thank you for that story I wasn't aware of! Considering the mentioned hardware and software I suppose it's around 30 years old?

Apparently lobbying is running deep in Germany...
We'll get to a cleaner world - hopefully, eventually.

Especially because the tax cuts will be pocketed by petrol corporations at least in part instead of making gas guzzling cheaper. Who doesn't want to increase big petrol profits at the expense of the community (because eventually the people need to pay for the tax cuts one way or another...).
Short-term your proposal makes sense - and a lot more than what seems to be done in Germany.
Long-term the only available and viable solution is making electric vehicles more attractive (by subsidizing them, the electricity to operate them and/or punishing the purchase of ICE cars).

When looking at new cars it's easy to make a case for EV.
When buying used it's a different thing, especially if the car is more than a few years old.
A few year old combustion engine cars are lot cheaper than comparable electric ones.
And a lot of years old EVs often have batteries with serious degradation, because battery (thermal) management was way less advanced when they were produced.
We are in trying times, but the prospect is getting better and better for EVs.

Riddle me this: where are the ultimate disposal places for nuclear waste and how much does it cost to operate them for the next tens of thousands of years - at least. Please do enlighten me about the (technically and economically) working solutions for nuclear waste. But I do agree that fossil is shit now and it was then.
And there's zero risk of radioactive contamination when using solar (or hydro or wind), statistics my ass.
Have you ever heard of the disaster at Chernobyl? And it was close more often: https://en.wikipedia.org/wiki/List_of_nuclear_power_accidents_by_country
Calling the certainty of nuclear waste and the risk of contamination vibes is as ridiculous as it can get.
Btw. there's a difference between risks that affect people once and risks that affect people for centuries.

The cost of installing solar has gone down fro quite a while (https://ourworldindata.org/grapher/solar-pv-prices) and depending on your region you can harvest around 1 kWh annually per 1 Watt peak power.
With the price per Watt being a fraction (2024: $0.26) of a Dollar and the life span of solar modules being in the decades, it really is a no-brainer whether you want to install them or not.

While they degrade over the years, they still retain close to 90% of their original power after 20 years and above 80% after 30 years.
They're basically free from maintenance.
The inverters may not last that long, but even for quite big installations at home in the range of double-digit kilowatt peak with annual electric energy procution in the double-digit MWh range, they cost only a few hundred bucks.

The biggest part (by mass) of solar panels is glass, which you are aware can be recylced until the cows come home.
Another big part is aluminum. Recylcing wise the same as glass.

And if you really want to replace them after decades, the amount of material that can't be recycled is quite small and not hazardous. Put it in the landfill.
Wind turbines are in part different as the blades typically can't be recycled afaik. At least they're in the category of non-hazardous waste as well and just like solar panels wind turbines last a very long time plus the towsers and the generators can very well be recylced/reused.
Alas they require more maintenance than solar.

The bigger challenge than finding cheap and not dangerous sources of electric energy at the moment appears to be the storage.
With more and more electric vehicles being on the street and each of them with capable batteries this can be a part of the storage solution alongside of grid-storage.

I choose renewables over fossil and nuclear any time of the day.

The amount of highly dangerous waste (e.g. fuel rods) may be small, but, well, it's highly dangerous and not only because of the immediate danger from radiation, but because it can be weaponized.

I agree and understand that converting mass to energy makes absurd amounts of energy available.

Aren't especially the fuel rods more dangerous than the uranium, that has been dug from the earth, because it's a mix of radionuclides with in parts complex decay chains?
Doesn't almost all uranium that has been dug up (according to wikipedia 99.3%) have a half-life of 4.463×109 years (before being used as fuel rod)?
Which made the level of radiation smaller than for radionuclides with shorter half-life that are in the used fuel rods, right?

The propaganda from fossil against the dangers of radiation doesn't work well as long as especially coal plants emit vast amounts of dangerous radionuclides through their chimneys.

To be fair I could stomach continuing to use nuclear plants for some more time until the transformation to way more renawables and storage for electric energy has come a longer way.
After all it's no big difference, if you add some more nuclear waste to the already quite big pile.
I'd be adamant if we were talking about starting the first nuclear reactor ever, though.
Building new nuclear reactors now seems like the wrong way given how dirt-cheap solar has become.

SailfishOS seems to run quite nicely, but has the limitations listed by you.
PostmarketOS seems to run a tad worse, but is fully open source.
Wouldn't it make sense to support both, because otherwise there's some danger of a chicken and egg situation:
people don't use PostmarketOS, because it doesn't work well enough. People don't support PostmarketOS, because they don't use it.
SailfishOS could pave the way for people using Linux phones and developing the need for completely open source ones after they realize the limitations of SailfishOS.
I can see that happening to me at least, because I ordered a Jolla phone with SailfishOS, which will hopefully be delivered in a few months (batch #3). I chose SailfishOS over PostmarketOS because of their Android app compatibility layer being fully aware this part isn't open source and that I will eventually trying to get rid of that situation.
The demand for having a Linux phone soon that may be able to become my daily driver was more pressing than facing the risk of getting frustrated by PostmarketOS.

https://www.iea.org/countries/germany/electricity shows a different picture regarding electrical production.
Where's your source?
Btw. you can stop addressing/blaming me; you have no idea where I reside.

[–] zergtoshi@lemmy.world 2 points 2 days ago (2 children)

Because they don't have to factor in the cost of dealing with the nuclear waste.
This is an error that's been made and still being made everywhere.

Winter nights are often stormy: wind turbines do their job.

[–] zergtoshi@lemmy.world 2 points 2 days ago (3 children)

I searched for info and there seems to be a clear trend according to https://www.iea.org/countries/germany/energy-mix which fossil is going down, nuclear having gone to 0, total energy imports going down, renawables going up.
Do you say such a transformation can be done over night?
Looking at the USA in comparison I come to the conclusion that a lot of countries are on the right path.

 

Dear selfhosters!

I come to you in the hope of help for avoiding some rookie mistakes.
I plan to migrate my very diverse hard- and software environment to a single machine.

Current mode of operation

I operate several RaspberryPis, a hardware firewall running on OpenWRT and a NUC like mini PC.
The RaspberryPis more or less are there for a single function; one runs Nextcloudpi, two run PiHoles, another one runs iSpy.
The mini PC is for the tasks that are heavier on CPU, RAM or storage space.
Maintaing this has become somwehat cumbersome and a replacement is dearly needed. My plan is to move all to a Proxmox sever.
I do have a general idea how to set up things, but as I'm brand new to Proxmox, I fear that there's a lot of mistakes to be made. I haven't read all documentation, but enough to know that it's no easy task to set up and operate Proxmox properly.
I'm aware that not having server hardware (e.g. no ECC RAM) is not the best setup, but AFAIU at least having a data centre SSD and lots of RAM is a good start.

Hardware

In the future all services are meant to run on this machine:
Case/Mainboard: AsRock Deskmeet X300
CPU: AMD Ryzen 5 5600GT
RAM: 64 GB
Storage:

  • 480 GB SSD (Intel DC S4500 Series)
  • 4 TB SSD (Team Group MP44)
  • 16 TB HDD (Seagate Exos, yeah, I know, but realized too late...)
    OS: Proxmox 8.3.1

Future mode of operation

Here's a high-level scheme of what I plan to do:

  • Install Proxmox on the Intel SSD
  • Use the 4 TB SSD as storage drive for the machines
  • Use the 16 TB HDD as storage drive for backups and additional storage (for files that mainly get read like media) for the machines
  • Migrate each physical device to a virtual machine (or create a new one to replicate the service)
  • Repurpose the mini PC as Proxmox backup server

Help!

The areas where I think reading documents can't beat experience are:

  • Do I use BTRFS or ZFS? I tend to use ZFS because of its advantages when making backups. What would you do?
  • Do I use QEMU/KVM virtual machines or LXC/LXD cointainers? Performance wise QEMU emulating the host architecture should be the way to go, right?
  • I shy away from running all services as Docker on the same machine for backup/restore purposes and rather have VMs per service. Is there anything wrong with this approach?
  • I'd love to keep NextcloudPi (because it'd make it easy to migrate settings and files) and there's an LXD container for it. Would you recommend doing a switch to Nextcloud AIO instead?
  • I've equipped the Deskmeet X300 with a WiFi card and antennas. AFAIU trying to use WLAN instead of LAN will create some trouble. Has anyone running Proxmox on a machine with WLAN insteal of LAN access successfully?
  • I'm aware that Proxmox comes with a firewall, but I don't feel very confortable using a software firewall running on the same machine that hosts the virtual machines. Is this just me being paranoid or would you recommend putting a hardware firewall between the internet access and the Proxmox server?
  • What else should I think of, but haven't talked about/asked yet?

Thank you very much for your time and your suggestions in advance!
