  1. Are you still playing this game? if you have plumbers you can extract the gas into bottles but thats isnt fast dumping it into space is an option or you could use a carbon skimmer to turn it into polluted water or you can feed it to slickters

    Bash array

    pretty sure you'll have to pass each item/line to it at a time
  3. Just ssh forward the port to your vps
  4. unijab

    Bash array

    unset my_array declare -a my_array my_array="" format () { my_array+=("element $1") } export -f format for x in 1 2 3 4 5 6 7 8 9; do format $x done echo ${my_array[*]}
  5. Never was that true. You are confusing diff things.
  6. Is there a reason AMD gpus can't be used with VR games?
  7. If you are using Linux and lvm, lvmcache is built in.
  8. I would go with something like.... Get a couple 9400-16i hbas. Get the u.2 cables that connect to the hba Then get the u.2 to m.2 adapters. Depending on your os and motherboard... Hot plug should work. even If not it should support 8-16 m.2 nvme drives
  9. I avoid windows, so i dont use smb I use targetcli to export "luns" from my storage system to my proxmox system. I have sync=always and a ssd drive for slog. I max'd out ram on my motherboard so I dont have any l2arc configured. heres a recent fio test from within a VM with a lun passed thru.

  10. just zfs set sync=always dataset/name
  11. what ever is cheapest with the warranty period you are happy with.
  12. both chips have the same power draw limits. any gains IMO are pretty neat when you consider 32 vs 64 cores using the same power draw.
  13. optane is not NAND optane is 3d xpoint in the video; they said AMD said not to use it (reading b/t the lines..... b/c its an INTEL product)
  14. mostly mis information the chipset limitation on intel is only if you were going to use it for the drive caching shit they offered (i forgot the name) optane memory is also just an ssd (limited to pcie x2 lanes) they can run in any m.2 slot that supports nvme.
  15. no optane memory was just a marketing stunt intel pulled for launch. (imo b/c the drives were so small (16GB or 32GB) that you couldnt install a windows OS on it directly) They are just small SSDs I know many people that use them for freenas or vmware boot drives.
  16. actually they are slower in peak bandwidth compared to a handful of other top end NVME ssds. Optane has low access latency which gives them better IOPs at lower queue depths
  17. I've had luck renaming the vmdk files to dot raw and using them with proxmox.
