==Install / Reinstall==

Uninstall according to the Asahi Wiki "partition cheatsheet"

https://leo3418.github.io/asahi-wiki-build/partitioning-cheatsheet/

Install with the provided script at

https://alx.sh|sh

Pay attention when you must reboot after step 1 into Step 2! It's the part where you hit "enter" for shut down and must wait 30 seconds and then keep the Power Button pressed down to restart with a Prompt about choosing what to boot.

Now Ardour is a flatpak unfortunately ; there's 2 providers, Fedora and
(seeing the apple or a "macos recovery" splash at this stage is normal ; just wait for the terminal to pop up with instructions)

Local Policy Update takes time. Please wait.

Keep ignoring the patronizing apple about the security of your device. enter mac username and password as asked.

==To The Bug==

I am trying to reproduce a bug with Ardour that kills the nice sound hack from the asahi people to put the 6 speakers into a combined stereo pair thanks to speakersafetyd. I need Ardour (as a tool), and I need patch to bluetooth and internal too.

https://github.com/AsahiLinux/speakersafetyd

1. Fresh install of 39 from "welcome start setup"

Note: keyboard, possibly language, should be first step here.

2. Enable 3rd party (I need the Codecs)

3. Reboot for good measure, accepting the "critical update" request from Gnome Software

---------------------------Freshly booted, virgin, updated-------------------------------------

4. Check the wireplumber install with an eye on the arch wiki:
- No pipewire-audio to be found
- Pulseaudio is on pipewire-pulseaudio, installed by default
- Same for pipewire-alsa
- BUT not for jack, where jack-audio-connection-kit is the default
- Asahi-audio is installed and up-to-date
- Lv2-bankstown same, speakersafetyd same

--> checking out VLC ; Settings now has 2 outputs, "internal" and "macbook" ; "internal" doesn't work.
- VLC set output module to Automatic, Alsa or Pipewire, sound works

--> Install helvum for visualisation of patch: everything fine, "macbook pro j414" are 2 inputs (and 6 outputs lol)

So far so good, good sound. But we haven't touched Jack yet - not that I need Jack ; what I need is Ardour with an internal patch

--> Adding Audacity, default settings ; plays nice with VLC into Helvum ; reset VLC to default which says "default alsa output currently pipewire media server"

Let's get to Ardour8 now, from Fedora not Flatpak this time (I noticed the issue with both Flatpaks, Fedora and Flathub)

Ardour Breaks Everything as soon as it is launched ;

- Volume goes 100% unamanageabe through keyboard,
- Nice 2 inputs "macbook pro speakers" disapears, replaced with everything times 6 wired to "Build-in audio speakers"
- Must Kill everything else that was running on loop (vlc and audacity) to start Ardour in Alsa config ; can't start otherwise
--> notice helvum empty, sound settings on "dummy output"

The kill is absolute ; a reboot seems needed. This was with Ardour on Alsa (choice is alsa, pulse, jack)

- Second attempt ; ardour kills the dual input macbook speaker module but speakersafetyd seems to be running

- Restarting speakersafetyd changes nothing
- stopping in kills sound (used vlc for test ; vlc outputs 6 into the 6 speakers - I'm afraid I'm sending full-spectrum 100% signal into each one of them, at risk of damage). Stil no control over volume.

- Third attempt ; fresh boot, settings / audio / helvum all good ; last Ardour use was on Pulse ; ardour splashscreen doesn't kill nothing, goes to audio-midi setup step (with pulse preselected) without complaints. Volume keys work, Speakers work, settings on "MacBook Pro J414 Speakers" - opening a new 48khz pulse session now...

Ardour is up, with nothing in it tho. There's a stereo output to the stereo speakers
--> this is useless, Ardour doesn't see VLC, Helvum doesn't "see" the ardour input tracks
- Crashed when I manually stopped the audio engine to switch to jack, killing volume buttons and resetting all to 6 channels

- four : jack ; fails with Jack complaining it hasn't got permissions to get a real time session ; sound settings shows "dummy output" only, Ardour crashes it all - note : this is without pipewire-jack, this on default Jack-connection-kit
Later startup crashes shows other crash info like impossibility to connect to socket

- Five : install pipewire-jack now. And now it works :)

Admin: /* Full YT to GoButton gymnastics */

'''''these are more recipes, or even just sample of CLI that works in real life.'''''
daughter machine : Model T440s Type 20AR serial PC00L2HW[https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t440s/20ar/20ars32p00/pc00l2hw/parts/display/as-built] , 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)

Current machine L460. It's slower than my T420s

== 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 [https://www.lostsaloon.com/technology/how-to-sort-du-command-output-by-size-in-linux/ 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[https://wiki.archlinux.org/index.php/Pacman#Cleaning_the_package_cache]

== 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.

Admin:

Following the [https://wiki.archlinux.org/title/Installation_guide guide] is mostly ok ; A word on something I completely forgot about :

==Read The FINE Manual==

(Assuming you have a thumbdrive ready and working)

* Use F12 on Fatitude to get to the Choose Your Boot Media at startup
* Load correct keymap :

# loadkeys fr-latin1

* Network interface probably gonna be wlan0 ; in doubt, do '''ip link'''

* Use [https://wiki.archlinux.org/title/Iwd#iwctl iwctl] to connect to the wireless network
[iwd]# station wlan0 scan
[iwd]# station device get-networks
[iwd]# station device connect SSID
[iwd]# exit
# ping archlinux.org

# timedatectl

* Check [https://wiki.archlinux.org/title/Installation_guide#Partition_the_disks partitions] architecture :

# fdisk -l

* Only format your root partition to install a fresh system on it. Add swap if you have swap:

# mkfs.btrfs -f /dev/sda6 (the -f option is to override former btrfs subvolumes)
# mkswap /dev/sda8

* Mount the filesystems you're going to use on the /mnt folder of your live system:

# mount --mkdir /dev/sda2 /mnt/boot/efi
# mount --mkdir /dev/sda7 /mnt/home
# mount /dev/sda6 /mnt/
# swapon /dev/swap_partition

* Now start reading '''Yes, but'''

==Yes, but==
- '''Yes, there's probably no need to partition''' if ''there's no need to!'' (esp EFI) You'll run into a permissions nightmare on your /home, but that's better than loosing data :

When the /home partition is mounted to /mnt/home at 'pacstrap' time, just '''chmod -r 777''' the entire contents of the previous /home folder ;
when you make your new user, be sure to give it another name.

- '''Only format your system / partition''' (or root partition) with ''makefs.<type of filesystem> -f'' is enough for a fresh re-install.

- It's ok to mount the EFI partition to /boot/efi and not simply /boot so as to not fill that small partition with everything in /boot, especially numerous kernels

On my fresh install, the EFI partition is 260MB which is a factory default - and my /boot partition is already 268MB ;
ergo, it wouldn't fit, with just 4 kernels + the windows stub

Restoring your system to a snapshot does not.

Following the [https://wiki.archlinux.org/title/Installation_guide guide] is mostly ok ; A word on something I completely forgot about :

==READ THE Fine MANUAL==

(Assuming you have a thumbdrive ready and working)

* Use F12 on Fatitude to get to the Choose Your Boot Media at startup
* Load correct keymap :

# loadkeys fr-latin1

* Network interface probably gonna be wlan0 ; in doubt, do '''ip link'''

* Use [https://wiki.archlinux.org/title/Iwd#iwctl iwctl] to connect to the wireless network
[iwd]# station wlan0 scan
[iwd]# station device get-networks
[iwd]# station device connect SSID
[iwd]# exit
# ping archlinux.org

# timedatectl

* Check [https://wiki.archlinux.org/title/Installation_guide#Partition_the_disks partitions] architecture :

# fdisk -l

* Only format your root partition to install a fresh system on it. Add swap if you have swap:

# mkfs.btrfs -f /dev/sda6 (the -f option is to override former btrfs subvolumes)
# mkswap /dev/sda8

* Mount the filesystems you're going to use on the /mnt folder of your live system:

# mount --mkdir /dev/sda2 /mnt/boot/efi
# mount --mkdir /dev/sda7 /mnt/home
# mount /dev/sda6 /mnt/
# swapon /dev/swap_partition

* Now start reading '''Yes, but'''

==Yes, but==
- '''Yes, there's probably no need to partition''' if ''there's no need to!'' (esp EFI) You'll run into a permissions nightmare on your /home, but that's better than loosing data :

When the /home partition is mounted to /mnt/home at 'pacstrap' time, just '''chmod -r 777''' the entire contents of the previous /home folder ;
when you make your new user, be sure to give it another name.

- '''Only format your system / partition''' (or root partition) with ''makefs.<type of filesystem> -f'' is enough for a fresh re-install.

- It's ok to mount the EFI partition to /boot/efi and not simply /boot so as to not fill that small partition with everything in /boot, especially numerous kernels

On my fresh install, the EFI partition is 260MB which is a factory default - and my /boot partition is already 268MB ;
ergo, it wouldn't fit, with just 4 kernels + the windows stub

==Default install through pacstrap needs a lot more stuff, you'll probably want==

Admin: /* ==READ THE Fine MANUAL */

Following the [https://wiki.archlinux.org/title/Installation_guide guide] is mostly ok ; A word on something I completely forgot about :

When you use a graphical installer, it will both assist in creating / deleting / reorganizing partitions, then at formatting them or not,
then in assigning their roles as "root", "home", or "swap" and so on ; I never realized those where completely independent actions, and that you
can partition or not, format or not, and, ''assign partitions'' with [https://wiki.archlinux.org/title/Installation_guide#Fstab fstab] later on independently.

====READ THE Fine MANUAL==

(Assuming you have a thumbdrive ready and working)

* Use F12 on Fatitude to get to the Choose Your Boot Media at startup
