If i mostly use CTs/LXCs the impact should be minimal (in theory), maybe even better if i dont have everything powerd up.

That's interesting, haven't considered that. Although I would want to run most things in CTs/LXCs and not full VMs for performance reasons. And Proxmox has more DIY feel which i kind of like. If I fail with Proxmox, might give QubesOS a try.

I am trying to install and setup proxmox on laptop and use it as daily driver. I want to make network setup that can use both ethernet and WiFi, whichever is available and i want VMs to be able to access LAN because some things dont work otherwise (like NDI). I have writen config file that makes 2 bridges and every VM would have 2 interfaces. I havent installed Proxmox yet because i dont want to mess things up (it wouldn't be first time :) ). My question is does this config look ok and are there some recomendations.

/etc/network/interfaces

auto lo
iface lo inet loopback

# Ethernet interface
auto eth0
iface eth0 inet manual

# WiFi interface
auto wlan0
iface wlan0 inet manual

# Ethernet bridge
auto vmbr0
iface vmbr0 inet dhcp
    bridge_ports eth0
    bridge_stp off
    bridge_fd 0

# WiFi bridge
auto vmbr1
iface vmbr1 inet dhcp
    bridge_ports wlan0
    bridge_stp off
    bridge_fd 0

I think he meant relative cost (including time)

I dont understand what service you would give or get from that.

Something like filecoin, you can provide storage or buy storage without need for some external exchange. Because it is basically "baked in" the crypto (or should be, i am not completely sure it works that way).

[-] RealBot@lemmy.world 1 points 7 months ago

Probably best way to have stable crypto is to have the crypto inherently provide some kind of service, something like filecoin. In that case value of crypto would be closely tied to memory/storage price.

Yeah, I was thinking it would be hard to store that amount of data in QR code even if image quality was reduced.

My cousin had an idea to make (print) an album but wanted to do it with QR codes because it would be cheaper to print (only black and white printing is required).

Is there some app that takes multiple images and generates QR code, and of course that it can also do reverse so you can scan QR code and view images.

QR code should contain images, not link to images.

It specifies which employers are cover with the WARN act, not employees. It either covers whole company (all employees in company) or no one at company at all.

The benchmark with 1B rows in this blogpost seems irrelevant for comparing performance of different programming languages.

It seems like the execution time of a program would be dominated by loading data from the file. And a lot of people posted solution with specs of cpu but not specs of disk (hdd, ssd, raid) although that seems more relevant.

Why would they compare languages and solutions in this way?

[-] RealBot@lemmy.world 1 points 8 months ago

In a lot of balkan languages this is similar to how you would say girl friend (we spell it frendica) so it's kind of interesting

..ahh, you gotta love that head bashing. It definitely helps if you're masochist.😂

[-] RealBot@lemmy.world 1 points 10 months ago

True, but algorithms they used in this article are just a "level" higher than primitive statistics methods and even that is not mainstream in kernel parameter (and similar things) optimisation. So it might be some time before we see more advanced methods used for this stuff.

You definitely shouldn't overprovision cores (logical cores, 16 in your case), especially for gamming VM. Because you are not going to get more performance, you are only going to increase overhead of context switching. One way to "pin" VM to half of cores is to give your VM 8 vCPU and increase vCPU units value (default is 1000). vCPU units determines VM priority in case of more work than CPU can handle.

https://forum.proxmox.com/threads/cpu-units.1047/

Basicaly if you have 2 VMs with default value of 1000 and CPU can't handle everything, proxmox will give both VMs equal cpu time (50/50).

But if for example you give first VM 3000 vCPU units, then under heavy load CPU time will be divided 75/25.

Time on CPU will be proportional to given vCPU units (under load).

So if you want to "pin" VM to 8 logical cores, then give VM 8 vCPUs and increase vCPU units (depending how big of priority you want).
