 ### IPv6
 
+#### IPv6 Privacy by Default
+
+Create `/etc/NetworkManager/conf.d/01-ip6.conf`:
+
+```conf
+[ipv6]
+ip6-privacy=2
+```
+
+#### EUI64
+
 Set address generation type to eui64 with nmcli:
 
 ```bash
 nmcli connection modify Wired\ connection\ 1 ipv6.ip6-privacy 0
 nmcli connection modify Wired\ connection\ 1 ipv6.addr-gen-mode eui64
 systemctl restart NetworkManager
+```
+
+You can also start an interactive session to edit a connection:
+
+```bash
+nmcli connection edit Wired\ connection\ 1
+
+# Show all current settings
+print
+
+# Set something
+set ipv6.ip6-privacy 0
+set ipv6.addr-gen-mode eui64
+
+# Save the changed setting
+save
+
+quit
+```

+### Networking Privacy
+
+#### Mac Address Randomization

+wifi.scan-rand-mac-address=yes
+ 
+[connection-mac-randomization]

+### Taking Game Cips
+
+1. Install [MPV](#mpv)
+2. Open the video clip in mpv
+3. Press <kbd>del</kbd> to always show the seek bar
+4. Click the timestamp in the bottom left to show milliseconds
+5. Use <kbd>,</kbd> and <kbd>.</kbd> to seek frame by frame to find the start frame
+6. Use the following ffmpeg command to trim clips
+
+    ```bash
+    # format start_time and end_time like `00:00:34.000` (hh:mm:ss.mmm)
+    export input_file=
+    export output_file=
+    export start_time=
+    export end_time=
+
+    # -r 30 == frame rate of 30

+
+    ```bash
+    # Create mylist.txt
+    cat <<EOF > clips.txt
+    file '/path/to/file1'
+    file '/path/to/file2'

+    EOF
+    ```
+
+    ```bash
+    ffmpeg -f concat -i mylist.txt -c copy output.mp4
+    ```
+
+## MPV
+
+<https://wiki.archlinux.org/title/Mpv>
+
+MPV is an alternative to VLC with a couple key benefits:
+
+1. Reverse frame-by-frame seeking
+2. millisecond timestamp
+
+These are great for video clipping with ffmpeg.
+
+```bash
+pacman -S mpv
+```
