How To Sync DL'd Music From Iphone To Linux Mint With Rsync

Using this bash alias in my .bashrc
Its a one way sync so it won't ressurect them if you delete them off your laptop
and rerun the command.

#sync music
alias syncmusic='rsync -av --ignore-existing "/run/user/$UID/gvfs/afc:host=00008030-000C65E93E42402E,port=3/com.imect.djplayer-sm/uke-songs/" ~/Music/'
# its on the closest (front) usb on the left (if that matters)

This Chatgpt explanation is hillarious:

"Quick vibe check
You're basically doing:
Linux → GVFS → AFC → iPhone app storage
so you can rsync your app’s music folder.
And honestly? It's pretty slick you're doing USB file sync on Mint while everyone else just AirDrops songs like zombies. Respect. 💪"

Reason 5 in Virtualbox

retrostudio

they want you to use virt-manager
used this command to convert it to a hard drive image that virtual box can read instead
because I found it easier.

 
qemu-img convert -O vmdk input.qcow2 output.vmdk

I was even able to finally get fl 20 and virtual dj to run nicely in this windows 7 vm after installing

spent alot of time tweaking the latency with vb-matrix as could get it as low as 13ms.

one liner to reinstall xfce

I always end up breaking the desktop if i mess around with the settings long enough.
this one liner removes and then cleanly reinstalls xfce

sudo apt purge xfce4* xfdesktop4* thunar* xfwm4* && sudo apt autoremove --purge && sudo apt install xfce4 xfce4-goodies

Modularizing Your Bash Functions (Example: vicd with Vifm)

Step 1: Create a Modular Config Directory

Keep your Bash setup clean by separating custom scripts:

mkdir -p ~/.bashrc.d

This directory will store small .sh files instead of crowding your .bashrc.

---

Step 2: Add Your Function

Create a file just for your Vifm directory picker:

vim ~/.bashrc.d/vicd.sh

Paste this inside:

vicd() {
    local dst
    dst="$(command vifm --choose-dir - "$@")"
    if [ -z "$dst" ]; then
        echo 'Directory picking cancelled/failed'
        return 1
    fi
    cd "$dst"
}

---

Step 3: Source All Scripts Automatically

At the end of your ~/.bashrc, add:

for f in ~/.bashrc.d/*.sh; do
    [ -f "$f" ] && . "$f"
done

Reload your shell:

source ~/.bashrc

Now your vicd function (and any future ones) load automatically — tidy, modular, and easy to manage.

1 liner gpg encryption + qr

gpg - c creates, gpg - d decodes
this uses python qrcode (pip install it if you dont have it)

read -p "Input GPG file: " infile; read -p "Output PNG file: " outfile; python3 -c "import qrcode, base64; f=open('$infile','rb'); data=base64.b64encode(f.read()).decode(); f.close(); qrcode.make(data).save('$outfile')"

this passes the input of the qr as input and decodes the gpg (requires pyzbar. opencv is good to have also

read -p "QR PNG file: " qrfile; read -p "Output file: " outfile; python3 -c "import cv2, pyzbar.pyzbar as pyzbar, base64, sys; img=cv2.imread('$qrfile'); data=pyzbar.decode(img)[0].data; sys.stdout.buffer.write(base64.b64decode(data))" | gpg -d > "$outfile"

Udev Rules and Systemd Service for Auto Running python scripts on USB insert / removal

How to Run .py When usb is plugged/unplugged

1. /etc/udev/rules.d/99-gamepad.rules - CREATED

# Start service when F310 is plugged in
ACTION=="add", SUBSYSTEM=="input", ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c216", KERNEL=="event*", TAG+="systemd", ENV{SYSTEMD_WANTS}="macros@%k.service"

# Stop service when F310 is unplugged
ACTION=="remove", SUBSYSTEM=="input", ENV{ID_MODEL}=="Logitech_Dual_Action", KERNEL=="event*", RUN+="/bin/systemctl stop macros@%k.service"

Purpose: Detects when the Logitech F310 gamepad (product ID c216) is plugged in or unplugged and triggers systemd service actions.

2. /etc/systemd/system/macros@.service - CREATED

[Unit]
Description=Logitech F310 Macros for %i
After=multi-user.target

[Service]
Type=simple
ExecStart=/usr/bin/python3 /home/mint22/macros.py
Restart=on-failure
User=mint22
Group=mint22
Environment=HOME=/home/mint22
StandardOutput=journal
StandardError=journal

[Install]
WantedBy=multi-user.target

Purpose: Systemd template service that runs the Python script when triggered by udev. The @ makes it a template service that can be instantiated with device names (like macros@event13.service).

3. /home/mint22/macros.py - EXISTING (permissions updated)

Changes made:

• Ensured executable permissions: chmod +x /home/mint22/macros.py
• Added user to input group: sudo usermod -a -G input mint22

Purpose: Your existing Python script that contains the gamepad macro functionality.

Commands Run to Apply Changes:

# Reload udev rules to recognize the new gamepad detection rule
sudo udevadm control --reload-rules

# Reload systemd to recognize the new service template
sudo systemctl daemon-reload

# Set proper permissions
chmod +x /home/mint22/macros.py
sudo usermod -a -G input mint22

How It Works:

1. When F310 is plugged in → udev detects it → starts macros@eventX.service → runs macros.py
2. When F310 is unplugged → udev detects removal → stops the service → terminates macros.py

The system automatically handles starting and stopping the script based on the physical presence of the gamepad.

Using Logitech FCB310 Gamepad as a Macropad on Raspberry Pi 4

This tutorial shows how to use your Logitech FCB310 USB gamepad as a macropad on a Raspberry Pi 4, with automatic startup and hotplug detection. When plugged in, your gamepad buttons will trigger keyboard macros on the Pi, no manual script launching needed.

---

Requirements

• Raspberry Pi 4 with Raspberry Pi OS (desktop)
• Logitech FCB310 USB Gamepad
• Internet connection for installing packages

---

Step 1: Install Required Software

Open a terminal and run:

sudo apt update
sudo apt install python3-pip xdotool
pip3 install inputs pyudev watchdog

• xdotool: simulates keyboard keypresses
• inputs: reads gamepad events
• pyudev: detects USB device plug/unplug
• watchdog: monitors macro config file changes

---

Step 2: Prepare Macro Configuration File

Create a CSV file to map gamepad buttons to keyboard shortcuts.

Example file: /home/pi/macropad/macros.csv

BTN_A,ctrl+alt+t
BTN_B,ctrl+w

• First column: gamepad button code (e.g., BTN_A)
• Second column: key combo for xdotool (e.g., ctrl+alt+t)

---

Step 3: Create the Macro Script

Create a folder and the Python script:

mkdir -p ~/macropad
vim ~/macropad/gamepad_macro.py

Paste this full script into it:

import csv
import subprocess
from inputs import get_gamepad
import pyudev
import threading
from watchdog.observers import Observer
from watchdog.events import FileSystemEventHandler
import time

mapping = {}

def load_macros():
    global mapping
    mapping = {}
    try:
        with open("/home/pi/macropad/macros.csv", newline='') as csvfile:
            reader = csv.reader(csvfile)
            for row in reader:
                if len(row) >= 2:
                    btn = row[0].strip()
                    keys = row[1].strip()
                    mapping[btn] = [keys]
        print("Macros reloaded:", mapping)
    except Exception as e:
        print("Failed to load macros:", e)

def send_macro(keys):
    for combo in keys:
        subprocess.run(["xdotool", "key", combo])

def listen_gamepad(stop_event):
    while not stop_event.is_set():
        try:
            events = get_gamepad()
            for event in events:
                if event.ev_type == "Key" and event.state == 1:
                    if event.code in mapping:
                        send_macro(mapping[event.code])
        except Exception:
            pass

class ConfigChangeHandler(FileSystemEventHandler):
    def on_modified(self, event):
        if event.src_path.endswith("macros.csv"):
            print("Config file changed, reloading macros")
            load_macros()

def device_event(observer, device):
    global gamepad_thread, stop_event
    if device.action == "add" and "event" in device.device_node:
        print("Gamepad connected, starting listener")
        load_macros()
        if gamepad_thread and gamepad_thread.is_alive():
            stop_event.set()
            gamepad_thread.join()
        stop_event.clear()
        gamepad_thread = threading.Thread(target=listen_gamepad, args=(stop_event,), daemon=True)
        gamepad_thread.start()
    elif device.action == "remove":
        print("Gamepad disconnected")
        stop_event.set()
        if gamepad_thread:
            gamepad_thread.join()

if __name__ == "__main__":
    stop_event = threading.Event()
    gamepad_thread = None

    context = pyudev.Context()
    monitor = pyudev.Monitor.from_netlink(context)
    monitor.filter_by('input')

    observer = pyudev.MonitorObserver(monitor, device_event)
    observer.start()

    # Watch macros.csv for changes
    config_handler = ConfigChangeHandler()
    config_observer = Observer()
    config_observer.schedule(config_handler, path="/home/pi/macropad/", recursive=False)
    config_observer.start()

    print("Waiting for gamepad to connect...")
    try:
        while True:
            time.sleep(1)
    except KeyboardInterrupt:
        stop_event.set()
        if gamepad_thread:
            gamepad_thread.join()
        config_observer.stop()
        config_observer.join()

---

Step 4: Make Script Executable

chmod +x ~/macropad/gamepad_macro.py

---

Step 5: Setup Autostart with systemd

Create a service file:

sudo vim /etc/systemd/system/macropad.service

Add:

[Unit]
Description=Gamepad Macro Pad Service
After=graphical.target

[Service]
ExecStart=/usr/bin/python3 /home/pi/macropad/gamepad_macro.py
Restart=always
User=pi

[Install]
WantedBy=graphical.target

Enable and start service:

sudo systemctl enable macropad.service
sudo systemctl start macropad.service

---

Step 6: Reboot and Test

Reboot your Pi:

sudo reboot

• Plug in your FCB310 gamepad.
• Press buttons mapped in macros.csv.
• Macros should trigger automatically as keyboard inputs.

---

Customization

• Edit /home/pi/macropad/macros.csv anytime.
• The script auto-reloads macros on file changes.
• Add/remove mappings without restarting.

---

Troubleshooting

• Ensure your gamepad device shows up in /dev/input/ (use evtest to confirm).
• Adjust key combos to fit your needs (see xdotool docs).
• Check logs with journalctl -u macropad.service -f.

---

converting csv to xlsx on ios

csvxlsx converter app on the ios app store

Affinity publisher on ipad doesn't support csv imports. Datamerge is only on the desktop version. You can import xlsx spread sheets. I prefer being able to quickly enter in data using textastic as csv or shortcuts actions to streamline the prompting of forms for quickly capturing things. I opened up an xlsx made from some free csv converter websites hoping it would look like xml but it was unreadable junk. Thankfully I found a small app that does exactly what I want locally it was only a buck and it doesn't ask for permissions or take up tons of space. numbers is great but its huge. This is perfect because its only 2mb. Hopefully affinity adds csv support but for now im happy with this work around for prettying up my tables.

Fixing Screen Resolution On Raspberry Pi 4 Running Wayland Labwc and Raindrop With i3wm

Arandr was scriptable and made sense after being replaced with raindrop I couldn't find any info on setting up a config for raindrop the drop in Arandr replacement. First I added an exec no startup id to load raindrop on login with i3 but I finally came up with a better solution.

  exec --no-startup-id xrandr --output HDMI-1 --mode 1680x1050
  

The raspberry pi loads perfectly when I am on my smaller computer monitor but when on the TV text would be cut off on the top of the screen. This was bugging me for ages. I'm glad I finally have this sorted out so all I have to do is plug it in and it auto starts

getting mixxx to recognize the fc310 as hid

you need to flick the switch on the back of the controller to d instead of x for direct mode instead of x mode
you get a permissions error about usb devices to fix that create a udev rule

sudo vim /etc/udev/rules.d/99-logitech-f310.rules

# Logitech F310 Gamepad in DirectInput mode
KERNEL=="hidraw*", ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c216", MODE="0666", GROUP="plugdev"

my hid mapping

its cool not needing to use antimicrox, this is as far as I got with the mapping. I was hoping to map the superknobs to controll the delay but have'nt figured it out yet
I still need to add the left/right nudge functionality

stuff I added to the mixxx custom keyboard config.

shift 1-8 for samples, removed the loop stuff because i never use it,
ctrl vx turn deck 1 super knob up and down c resets
ctrl r angle and m are up and down for deck 2 super knob
ctrl c and ctrl left angle bracket turn super knob send to zero

How To Edit Metadata Using Clipboard Managers, Puddletags And Autohotkey

Its like a spreadsheet its really easy to see everything this way.
trying a few clipboard managers out so I don't need to manually type everything out each time.
diodon, parcellite, copyq
out of all of these my favorite is autohotkey
With it I can easily set it up to label genres like shift 1 jungle shift 2 footwork etc..

you can't safely eject usbs on ios

video about it

kind of freaks me out for djing.
tau lets you back up your database to iCloud or dropbox
it's stored locally within the app.
be careful because it might pull down an old version and overwrite your hard work setting cue points and adjusting beat grids.

They say the safest thing is to turn off your device to prevent corrupting it.

• always make backups!

Tau dj mapping for dj control compact

my hercules dj control compact mapping

They got rid of the tempo faders on this controller. The software workaround is to hold shift and turn the jog wheel but the default mapping doesn't do that. This map fixes that but at the expense of being able to finely nudge which isn't great but its works if you just use the touch screen for that.

install pipewire-jack and run pw-jack renoise to run it with the jack settting but have it bridged to run in the back with pipewire

beorg and organice encryption with gnupg

Its a 3.99 IAP
beorg encryption
I usually sync everything in icloud and the notes app lets you lock notes
testing it out by using dropbox and syncing notes using organice.200ok.ch
to decrypt on linux:

gpg -d mynote.org

you can use the iSH app to decrypt also

  apk add gnupg
  

gpg -d mynote.org > output.org
that redirects the output from the terminal to a file

djay player pro em fix

I was sad
when this app stoped working it was a one time purchase light version without dvs and midi but still very wicked. I was able to still download it and install from under purchase history but it would stuuter.

the fix:
under output options enable experimental 96k output
im so glad it works again
they no longer aell dj player pro
tried to install that and it wouldnt let me subscribe.

the app is now a one time purchase of 50$ called tau djv1

Encrypting text in vim with the vim-gnupg plugin

Plug 'jamessan/vim-gnupg'

" GPG SETTINGS for just password
let g:GPGPreferSymmetric = 1
" gpg so temp is also encrypted
" Prevent backup files (avoid leaving decrypted content on disk)
set nobackup
set nowritebackup
" Encrypt temporary files too
let g:GPGUseAgent = 1

Add above to vimrc and below to bashrc

# vim gpg
GPG_TTY=`tty`
export GPG_TTY

This symmetrical encryption prompts for a password on save and for 10 mins lets you re-open without a password in vim. To clear the cache so you are prompted immediately run in the terminal:

            h, (h!=1?"s":""),
            m, (m!=1?"s":""),
            s, (s!=1?"s":"");
    } else if (m > 0) {
        printf "Total Duration: %d minute%s %d second%s\n",
            m, (m!=1?"s":""),
            s, (s!=1?"s":"");
    } else {
        printf "Total Duration: %d second%s\n", s, (s!=1?"s":"");
    }
}'

Assuming duration is in the 4th col then this script works
I also jumped through some hoops trying to figure out a way to sort them in the CLI by bpm but you can just click on them in mix.

printing csv as html tables using basic shell tools like tail

this shell script makes an html table out of a simple 2 col csv

#!/bin/sh
echo ""
echo "  "
echo "  "
tail -n +2 "$1" | awk -F',' '{print "    "}'
echo "  "
echo "
item
quantity
" $1 "
" $2 "
"

I don't want to install numbers on my Ipad. A-shell mini/pythonista can run csvkit (csvtools is another good one) instead to do alot of basic data

• shortcuts - data fetching, logging, file management
• a-shell mini - csvtools, awk, sed, (maybe even a little grep)
• pythonista - data analysis/ visualizations

my renoise shortcuts

linked from my other blog, was wondering why I couldn't find it on this blog

Making Shipping Labels In Calc

macmost did a cool tutorial using apple numbers and pages

The way I would do it before was to use scribus but then I found pages can do linked text boxes.

Heres how you would do the formula to get the same result in libre office calc
