Proxmox on Laptop, Network Setup
  • 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.

  • Proxmox on Laptop, Network Setup
  • I would do everything in VMs, mostly Linux and probably one Windows. Proxmox would be only for managing VMs. I want everything in VMs because it's more flexible for partitioning storage and i can have both Linux and Windows runing at the same time (which can't be done with dualboot). I am student of computer science so i use it for programming, both for college and side projects. Sometimes there are a lot of programs i have so OS kind of gets bloated, not so much from performance standpoint but just mental overhead of having 10, 20, 30 programs and having to keep in mind what program needs what dependencies, env variables, etc.. so i want to kind of group them to VMs and CTs.

  • Proxmox on Laptop, Network Setup

    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 ```

    pitching an idea
  • Sure, they are not perfectly stable, there is always inflation (sometimes more, sometimes less).

    But its not as volatile as crypto. In last 24h difference between monero high an low is ~2% (which isnt terrible by itself but on a longer period its larger difference) and regular currency effectively has almost no volatility in 24h period.

    Acording to google 1 year inflation was ~3.4% for dollar. (so probably diff hig low is just a bit higher) Difference between monero 1 year low an high was greater than 20%. So monero is something like 6 times more volatile. (and i am not talking about inflation, but volatility)

    So its not exactly the same situation regarding stability.

  • But that only guarantees safe one way transaction. If that is all you want thats ok.

    But for safer transaction you want something like smart contracts. So you can actualy know you are gonna get what you buy for example.

    Without some kind of smart contracts you are actualy relying on exchanges (so in reality it isn't really trustless).

    Does monero have some kind of smart contract mechanism? In which case I am talking nonsense😂.

  • pitching an idea
  • Ok yeah, sure.

    But just being currency isn't enough for currency to be stable. So i dont see how that should affect its stability. The major reason why regular currency is stable is because it is already widely used.

  • pitching an idea
  • 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).

  • pitching an idea
  • 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.

  • QR code image gallery
  • 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).

  • QR code image gallery

    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.

  • Would there be a way to 3D print plastic part of a battery and just fill it with standard battery types (cylindrical batteries) and make them swapable? Because as far as i know there isn't really any electronics in batteries, just different voltages based on number of batteries in series and different mounting mechanism. It just seems like a silly vendor lock-in.

  • This benchmark seems irrelevant

    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?

    Tuning the Linux kernel with AI, according to ByteDance
  • 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.

  • Gaming VM and over-provisioning cores?
  • 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).
