Below is a script that can be used to convert all files in the directory to AV1
#!/bin/bash set -e find * -type f -iname '*.mkv' | grep -v av1 | while read -r mkv; do file=${mkv%.*} av1="${file}-av1.mkv" if [ -f "${av1}" ]; then echo "${av1} already there" # echo "${file} -> ${av1}" else echo "converting ${file} --> ${av1}" ffmpeg -i "${mkv}" -c:v libsvtav1 -crf 35 "${av1}" < /dev/null && echo "${av1}" >> completed.
Make required directories mkdir -p /userdata/mergerfs/VERSION_NUMBER && cd /userdata/mergerfs/VERSION_NUMBER
Download newest static mergerfs build, current built now can be found HERE
extract tar -xvzf FLIE_NAME.tgz
cd ../ && ln -s VERSION_NUMBER current
Create disk labels so we know what to add to the script, replace LABEL_NAME and /dev/sda1 with your disk info e2label LABEL_NAME /dev/sda1. Thankfully batocera mounts disks by label in the /media/ folder
Create script to mount nano mergerfs.
To disable sleep run the following commands
for f in $(ls -l /dev/disk/by-id/ | grep ata-ST | rev | cut -d'/' -f1 | rev | sed 's/9//g' | sed 's/1//g' | sort | uniq); do /opt/openseachest/openSeaChest-v23.03.1-linux-x86_64-portable/openSeaChest_PowerControl -d "/dev/${f}" --powerBalanceFeature disable; done

With my 16 port unifi PoE switch dieing I needed something cheap, while browsing eBay I found a HP 5500 and was able to make offer of $90 shipped.
Reading all docs I figured it was a procurve which has a Cisco like CLI, but man I was way wrong. Thankfully I was able to find a manual HERE. Took some time to learn, but it just works for my needs.
After updating gitea I was unable to create a repo in an organization as an owner. To fix this I had to run the following in mysql
mysql
update team set can_create_org_repo = 1 where lower_name = "owners" and can_create_org_repo = 0;
It should show at least one item was updating and now it will work as inteneded.
First we need to find the iGPU type
lspci | grep VGA
This should return something like 00:02.0 VGA compatible controller: Intel Corporation Device 4e55 (rev 01)
Add the following to /etc/modprobe.d/i915.conf, replace 4e55 with your type
options i915 enable_guc=3 options i915 force_probe=4e55 Now to we need to rebuild the initramfs to add the above
update-initramfs -u
Install the required firmware files
You need to enable the non-free source
apt install -y firmware-misc-nonfree intel-media-va-driver-non-free
Run the following in powershell
Test-NetConnection -ComputerName HOSTNAME -Port PORT
Something like the following will be the output. TcpTestSucceeded is the output you should be concerned with.
ComputerName : google.com RemoteAddress : 142.250.191.142 RemotePort : 80 InterfaceAlias : Wi-Fi SourceAddress : 192.168.1.5 TcpTestSucceeded : True
I don’t like IPv6 since all it does is cause issues, here is how to disable it for APT, you could do it system wide as well if you wanted
echo 'Acquire::ForceIPv4 "true";' | sudo tee /etc/apt/apt.conf.d/99force-ipv4
How to install stuff with apt, but exclude some items, all you need to do is add a - to the end of the package for example
apt install -t bullseye-backports cockpit cockpit-networkmanager-
Looks like the config recommendation for native ping causes issue with sudo
Changing this
[Service] CapabilityBoundingSet=CAP_NET_RAW AmbientCapabilities=CAP_NET_RAW to this
[Service] AmbientCapabilities=CAP_NET_RAW and it fixes the issues
A few fun tips for Proxmox
How to migrate VM to new host not in cluster Create NFS share on a system
Add NFS share as backup endpoint on new and old server
Run a backup of the system you want to migrate, I shut the VM down, but it’s no needed
On new host go to the NFS storage in the GUI and go to backups
You will see the backed up data
After upgrading to Windows 11 there’s a few things I can’t handle. One is the new taskbar and the other is the right click menu. To fix them you can do the following.
To fix the taskbar is using ExplorerPatcher. It might flag as a virus FYI. USE AT YOUR OWN RISK
To fix the right click menu open cmd and run reg add HKCU\Software\Classes\CLSID\{86ca1aa0-34aa-4e8b-a509-50c905bae2a2}\InprocServer32 /ve /d "" /f
By default Windows 11 requires a Microsoft Account to install. To bypass this do the following:
Hit Shift + F10
Type oobe\bypassnro and hit enter
The computer will reboot
By default mergerfs appears to try and mount before ZFS is mounted which causes the mergerfs filesytem to fail. To fix this we just need to add x-systemd.requires=zfs-mount.service to the /etc/fstab entry
For example my /etc/fstab entry is below:
/hdd*/mergerfs /data fuse.mergerfs splice_read,threads=4,allow_other,cache.readdir=true,cache.files=off,fsname=mergerfs,use_ino,dropcacheonclose=true,link_cow=true,category.create=mfs,cache.entry=120,cache.attr=120,x-systemd.requires=zfs-mount.service 0 0
Below is how to replace the battery on the Opple remote. It’s not as easy as it is with the others, but it’s still pretty simple. You can use a spudger or a flat head screw driver
First remove the middle key with the spudger, if you push down on one of the sides it makes it easier to lift the other
Now remove the screw from the middle.
Now remove the top button.
To use Grafana Bearer tokens you need to be able to inject headers which you can’t do in the OSS version of Screenly. To get around this you can just run a NGiNX proxy on the host and reverse proxy to the Grafana server and use NGiNX to inject the required headers.
I HAVEN’T TESTED THIS YET ON SCREENLY OSE, BUT SINCE IT’S JUST RUNNING ON RAPSBERRY PI OS THERE SHOULDN’T BE AN ISSUE, I WILL BE TESTING EVENTUALLY
How to share more than one calendar via link.
First share the calendar like you usually would to get a public link. Then you can combine the keys like below:
These two are the individual calendars
https://next.my.domain/apps/calendar/p/hjfu37fhcneydyxh
https://next.my.domain/apps/calendar/p/2u487fiuwf22fe98
You just take the part after the last / (slash) and add a - (dash) between more than one like below
https://next.my.domain/apps/calendar/p/hjfu37fhcneydyxh-2u487fiuwf22fe98
This link will show all calendars. Just split any calendars you want to share with the - (dash)
Only copy specific file extentions in folder
rsync -a --include '*/' --include '*.mp3' --exclude '*' source/ target/
Speed up rsync over SSH without needed to change any configs. arcfour is faster, but no longer enabled by default meanwhile aes128-ctr is
rsync -avhP -e "ssh -c aes128-ctr" /src/ user@ip:/dst/
rsync ssh with non standard port
rsync -avhP -e "ssh -p number" /src/ user@ip:/dst/
rsync ssh with non standard port and show full progress
I based this post on HERE
Just for reference, the things I did to make it work:
git clone https://github.com/tailscale/tailscale-android.git
nano tailscale-android/cmd/tailscale/backend.go
change:
func (b *backend) Start(notify func(n ipn.Notify)) error { b.backend.SetNotifyCallback(notify) return b.backend.Start(ipn.Options{ StateKey: "ipn-android", }) } to:
func (b *backend) Start(notify func(n ipn.Notify)) error { b.backend.SetNotifyCallback(notify) prefs := ipn.NewPrefs() prefs.ControlURL = "https://myheadscale.domain.com" opts := ipn.Options{ StateKey: "ipn-android", UpdatePrefs: prefs, } return b.backend.Start(opts) } nano Dockerfile
Add the below to the file:
Install resolvconf
sudo apt install resolvconf
Edit the base file with what you want to always be in the file
sudo nano /etc/resolvconf/resolv.conf.d/base
Have resolvconf rebuild the base
sudo resolvconf -u
Show logs from when systemd service last restarted. (This needs systemd > v232)
journalctl _SYSTEMD_INVOCATION_ID=$(systemctl show -p InvocationID --value SERVICE_NAME.service) | head -n15
NFS Mount with NFS and /etc/fstab
From all of my reading over the years it’s always been said to add _netdev to the /etc/fstab mount, but that never worked for me. After more reading it appears that was for SystemV which is dead. I figured it out after much Googleing.
