Average price of a list of search results on eBay

This is particularly useful when you want to know the going rate of an item you're planning to sell, i.e. in conjunction with the "Sold items" filter.

$x("//ul[contains(@class,'srp-results')]//div//span[contains(@class,'s-card__price')]").slice(0,22).map(x => Number(x.innerText.slice(1))).reduce((x,y) => x + y)/22

NB: 22 is the number of items I want to take and average. Adjust as needed to match the number of items that match your search (or limit the number of items you want to take the average of).

1. Create your LXC (Host: PVE 8.3, LXC: Debian 12). For hardware I went with 4 cores, 8GB RAM, 32GB storage.
2. In LXC: Create non-root user: adduser foo
3. Add to sudo: usermod -aG sudo foo
4. Set up SSH (see Arch wiki)
5. Install Docker: https://docs.docker.com/engine/install/debian/
6. Setup non-root Docker management: https://docs.docker.com/engine/install/linux-postinstall/
7. Follow step 2 here. [Archive Link]
   Note: Probably don't need to add group 44 (video) as Jellyfin (or more accurately, ffmpeg) uses the render group only (104).

This script allows you to analyse the ViewingActivity.csv file included in your Netflix data and outputs a list of shows watched by a particular profile ordered by frequency (i.e. number of times viewed and number of episodes viewed).

Usage

You will first need to request your Netflix data, download it and extract the zip file. You can do this by going to Account -> Security -> Personal information access

You will also need to install xsv or a similar tool.

Adjust the grep and awk expressions as appropriate. The grep expression will exclude lines where those strings are found (e.g. exclude teasers/trailers). The awk expression is necessary for specifying a cutoff for the show title to allow grouping of shows, e.g. Stranger Things: Stranger Things 2: Chapter One: MADMAX (Episode 1) will be transformed to Stranger Things to allow accurate counting of each shows views.

Migrate a Proxmox VM from SeaBIOS to OVMF (UEFI)

• Under the VM's Hardware tab, change BIOS from Default (SeaBIOS) to OVMF (UEFI) in the Proxmox web UI
• Click Add at the top and select EFI Disk. Select a location and click OK.
• Boot the VM using Boot Repair Disk. Alternatively, boot any live CD and install the Boot Repair tool. Instructions for Ubuntu here: https://help.ubuntu.com/community/Boot-Repair
• Use Gparted or your favourite partitioning tool to create an EFI partition. Note: You may need to resize your disk and adjust your partition layout.
• Run the Boot Repair tool and choose the recommended option. Follow the instructions

NB: This works on a disk partitioned using MBR.

Mount SMB share as non-root user with write permissions

sudo mount -t cifs -o "uid=$local_user,username=$smb_user,addr=$host" //$host/$share $mount_path

For errors:

• mount: $mount_path: cannot mount //$host/$share read-only
• mount: $mount_path: bad option; for several filesystems (e.g. nfs, cifs) you might need a /sbin/mount. helper program.
