these are more recipes, or even just sample of CLI that works in real life. daughter machine : Model T440s Type 20AR serial PC00L2HW[1] , 8G Ram (4G Soldered) 500G sHDD, Transcend 256Go SATA III 6Gb/s MTS430S 42 mm M.2 SSD 430S SSD TS256GMTS430S (instead of 3G Sim transmitter)

Full YT to GoButton gymnastics
Prep work
Arch Linux : Install yt-dlp from /extra Ubuntu : Install youtube-dl if needed with: (Maryam's ubuntu version of yt-dl is years late, doesn't work):
sudo apt update sudo pip3 install youtube-dl
The regular line for youtube-dl, uncompressed wav format and compressed mp3 is :
$ youtube-dl -x --audio-quality 0 --audio-format wav https://youtu.be/<yt code of video as found in title> $ youtube-dl -x --audio-quality 2 --audio-format mp3 https://youtu.be/<yt code of video as found in title>
Let's make some .bashrc alias :
Add anywhere near other "alias xx="xx -xx" the following for .wav, or MP3 in the .bashrc file, using nano or gedit :
alias getwav='youtube-dl -x --audio-quality 0 --audio-format wav' alias getmp3='youtube-dl -x --audio-quality 2 --audio-format mp3'
Actual transfers
Download the sound from any YT video : Open terminal, like hit "meta" key and start typing "term" ; input the following :
cd Musique [ENTER] getwav <full youtube address of file as copypasted from the adrress bar of the browser> [ENTER]
! Don't forget about the [TAB] autocompletion trick, and the [UP ARROW] find-me-latest-commands trick !
OR, if the video is very long and you don't want to choke your hard drive and your transfer times, use mp3 compression :
getmp3 <youtube address of file> [ENTER]
You can use middle click to paste into the terminal or Shift+Crtl+V (instead of the usual Shift+V) to paste the copied address
So your IRL process is like this :
Open Firefox, go to YT, find some zique Open Terminal, move to the appropriate Musique directory by typing cd Musique [ENTER]
* in Firefox triple-click to highlight youtube address in browser address bar * in Terminal, type getw [TAB], middle click next to getwav to paste YT address, [ENTER] or * in Terminal, type getm [TAB], middle click next to getmp3 to paste YT address, [ENTER]
That's it :)
Recommend you rename the files on the PC, it's easier than on the pad (but doing so you loose the source of your file since youtube-dl save the full title and youtube code of the ripped piece in its name).
On the Pad :
1. Make sure pad and laptop are on the same wifi network (can totally be your phone's Hotspot)
2. Open VLC, go to "résaux", hit "partage via WiFi", notice the IP "http://xxx.xxx.xxx.xxx" address, it's your iPad address on the local network.
3. in Firefox, open new tab and input same IP address, or even just try "ipad.local"
4. Paste using the big fat "+" button upper right corner
5. Using the File Manager, move new files from vlc to the GoButton folder, possibly there in yet another, specific folder for better organisation
GoButton: adding new files to your show
In GoButton, hit the "edit" button upper right, then the "+" ; add your desired "HIT" (not "cue", max 92 alas) ; add using the "add" button top right.
- Adjust the starting point by long-press, then sliding the leftmost side of the frame around the visualizer at the top. Zoom with pinch movement if necessary
Example : the "Dukas" has a lot of stuff we don't want before the main theme
- Edit the name to something more readable quickly if needed
- Choose appropriate color, like "sound effect", "mood music" etc
Example : The [FADE] effects are red to stand out against the various actual sounds
- Check volume using the green [Preview] button and adjust if necessary
Example : the "Hasret Flute" is stupid loud while the "Scarlatti" is underpowered
- Adjust the "stop others" rule : for musics, use [hits & cues] with fade out time of i.e. 3 seconds unless you need differently depending on the start of the music interrupting the others. For sound effects, don't do this since you may want several effects running at the same time, including over the music.
Example : The "DRIIING" sound effect cuts everything else dry, in zero seconds, since it is meant to kill everything Example : the "Shitty weather" effect doesn't stop anything as you may want it together with other sound or music
- Adjust "loop" properties if you need the sound to last longer / to be able to cover an entire act using either [FIXED] value of repetition or [INFINITE]
Example : the "dogs" effect is looped 4 times because the source file is too short Example : The "wind" effect is looped indefinitely because you may want it over an entire act
- - Adjust the end point too if you are using the loop function !
- You can add a keyboard shortcut using the [Triggers] function, select "keyboard" and your shortcut key
Example : The [SHARP FADE] effect is linked to the [S] key, like "stop"
- Don't forget to [SAVE] your editions upper right !
- Hit [DONE] when done to go back to playback mode
When your show is ready, organised, re-listen to all of them to be sure musics are somewhat equal, and sound effects can mix & live with them nicely.
Notes
After a few minutes without using it, VLC will close the connection, this is normal.
You need to stay on the vlc share page, or the sharing thing will shut itself down.
Downloading from YT is a moving target, it's normal and expected it will stop working at some point; first thing to do is updating youtube-dl
sudo pip install -U youtube-dl
Your source of copyright-free sound effects is https://pixabay.com/sound-effects AVOID YOUTUBE when you can, pixabay also has music :)
Mount nfs
From Nautilus
nfs://192.168.xxx.xxx:0/<Share to mount>
or...
nfs://192.168.xxx.xxx:/<Share to mount>
from the 'other locations' tab in Nautilus.
From Terminal
# mount 192.168.xxx.xxx:/<share to mount> ~/<destination folder/
the -t nfs doesn't seems to be needed most of the time. Don't forget to install nfs-utils lol
Query by size
From here
du -h $(du -b * | sort -n | cut -f2-)
Scan from network
Need reportlab, hplip, python imaging library. And possibly to run hp-setup -i just to wake things up.
[jph@ThinkDMX3 ~]$ hp-scan --device='hpaio:/net/OfficeJet_7510_series?ip=<ip address without port>' --output=output.pdf
When all said and working, scan in color at 300DPI with :
hp-scan -m color --size=A4 -o /dest/of/file/NameOfFile.pdf
Boot GRUB manually when failing to locate your kernel (use tab to fill)
Check disks available: grub> ls define root system: grub> root=(hd0,msdos1) Load the kernel image: grub> linux /boot/wmlinuz root=/dev/sda1 !! This could be, not sure, use Tab to autocomplete: grub> linux /boot/wmlinuz-linux root=/dev/sda1 Locate initial ramdisk: grub> initrd /boot/initramfs-linux.img Boot the damn thing & now tell me why GRUB isn't just doing it by itself grub> boot
Retrieved from https://www.unix-ninja.com/p/Manually_booting_the_Linux_kernel_from_GRUB
Also, upon install, don't save your grub config file as grub.conf...
Cleanup pacman's cache:
paccache -r[2]
Query both battery states
upower -i $(upower -e | grep 'BAT1') | egrep 'BAT1|energy' & upower -i $(upower -e | grep 'BAT0') | egrep 'BAT0|energy'
Add it as alias in .basrc as
alias BATT="upower -i $(upower -e | grep 'BAT1') | egrep 'BAT1|energy' & upower -i $(upower -e | grep 'BAT0') | egrep 'BAT0|energy'"
Needs double quotes because of the use of single quote in the command
WebDAV to ownCloud
Syntax for Nautilus access through WebDAV towards an owncloud instance :
davs://adress.ofyour.cloud/remote.php/dav/files/nameofuser
this will prompt for a username and password and bring you to the root of the File side of things, which is useless. Your actual share is network adress / files /username, not the visibly mounted network share that ony goes to adress.ofyour.cloud/remote/dav (which shows a bunch of stuff you can't do a thing to. be sure to bookmark it the real ./files/usermane location. The system creates a username and impossible password for you, be sure to not use the generic host creds. The actual line for me is davs://tic.<myserver>.net/remote.php/dav/files/<username as generated>
Force IPV4 GPG keys renewal / finding
IF it's just "missing keys" or "invalid" or such, try :
# pacman-keys --populate archlinux
or
# pacman-key --refresh-keys
Or the caveman way :
# pacman -S archlinux-keyring
If in yay, try this :
# gpg --keyserver keys.gnupg.net --recv-keys <insert key number here>
Or this for TOR for instance :
# gpg --auto-key-locate nodefault,wkd --locate-keys torbrowser@torproject.org
If #pacman -S archlinux-keyring fails after a global $yay -Syu aborted with some gpg keys gibberish, try this:
Fight stupid GPG keys that won't update other than over an IPV6 address :
I ran into this problem on MacOS 10.13.6, and I currently suspect it's something weird with gpg deciding to use IPv6. I currently don't have a valid global IPv6 address, so all IPv6 addrs should be "no route to host", but I noticed that if I manually look up keys.gnupg.net and substitute in one of the IPv4 addresses explicitly, then the command works and I can proceed, without doing the other workaround with curl. $ gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB gpg: keyserver receive failed: No route to host $ host keys.gnupg.net keys.gnupg.net is an alias for hkps.pool.sks-keyservers.net. hkps.pool.sks-keyservers.net has address 51.38.91.189 [...] hkps.pool.sks-keyservers.net has IPv6 address 2001:67c:26b4::98:0 $ gpg --keyserver hkp://51.38.91.189 --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB gpg: key 105BD0E739499BDB: 4 signatures not checked due to missing keys gpg: key 105BD0E739499BDB: public key "Piotr Kuczynski <piotr.kuczynski@gmail.com>" imported gpg: key 3804BB82D39DC0E3: 101 signatures not checked due to missing keys gpg: key 3804BB82D39DC0E3: public key "Michal Papis (RVM signing) <mpapis@gmail.com>" imported gpg: no ultimately trusted keys found gpg: Total number processed: 2 gpg: imported: 2
