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"

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.

came across this 5mb app on the hunt for a parametric modeller for cad stuff. you can import text files extrude them, set the background green and key them out in lumafusion to add cool 3d animated text. This is my basic script:

extrude {

metallicity 0.9
text words
}

a 6.99$ cad vectorizing app that seems promising for local offline use, 15mb. its nice to see something thats a one time payment instead of subscription.

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.

| BASE (Baseline Table) | OpenType table for baseline alignment across scripts (e.g., roman, ideographic, hanging). |
| JSTF (Justification Table) | OpenType table that supports script-specific justification (e.g., Arabic kashida). |
| Unicode | The universal character encoding standard covering nearly all scripts and symbols. |
| Blackletter | A Gothic script style (Textura, Fraktur) with medieval calligraphic texture. |
| Transitional Serif | Serif style between old-style and modern (e.g., Baskerville), moderate contrast. |
| Old‑style Serif | Serif faces with diagonal stress and bracketed serifs; inspired by Renaissance writing. |
| Didone / Modern Serif | High-contrast serif fonts with vertical stress and fine hairlines (e.g., Bodoni). |
| Display Typeface | Highly stylized fonts for headlines or large sizes, often too decorative for body text. |
| Text Typeface | Fonts optimized for body text and readability at small sizes. |
| Geometric Sans‑Serif | Sans fonts based on simple geometric shapes (e.g., Futura). |
| Humanist Sans‑Serif | Sans faces with calligraphic influence and subtle stroke contrast. |
| Neo‑Grotesque Sans‑Serif | Neutral, modern sans-serifs (e.g., Helvetica, Univers). |
| Script Typeface | Typefaces that mimic cursive handwriting or calligraphy. |

| Stylistic Set (ssXX) | Predefined alternate glyph sets that can be turned on manually. |
| Oldstyle Figures (onum) | Numerals with varied heights and alignments for flowing text. |
| Lining Figures (lnum) | Numerals aligned to cap height, consistent with uppercase letters. |
| Proportional Figures (pnum) | Numbers with variable widths designed for visual harmony. |
| Tabular Figures (tnum) | Monospaced numerals for tables and aligned columns. |
| Discretionary Ligatures (dlig) | Decorative ligatures applied optionally for stylistic effect. |

| Swash Capitals | Highly decorative uppercase glyphs, often with flourishing strokes. |
| Initial/Final Forms (init / fina) | Contextual forms used at the beginning or end of words (common in Arabic). |
| Split Diacritics | Diacritics positioned separately from base glyphs (e.g., Vietnamese). |
| Glyph Coverage | The set of Unicode blocks and scripts supported by a font. |
| Script Tag | An OpenType label identifying the script for a set of features (e.g., “latn”). |
| Feature Tag | A four-letter code defining OpenType features (e.g., kern, liga). |
| Lookup Table | A GSUB/GPOS structure defining specific substitutions or positioning rules. |
| Coverage Table | Specifies which glyphs are affected by a lookup in GSUB/GPOS. |
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.

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..

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.
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.

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:
gpgconf --kill gpg-agent
I downloaded FreeCad as an app image I want to create a desktop shortcut but I needed an Icon
./freecad.AppImage --appimage-extract
csvtool col 4 vertagogo.csv | tail -n +2 | awk -F: '{
min=$1;
sec=$2;
total += min * 60 + sec;
} END {
h = int(total / 3600);
m = int((total % 3600) / 60);
s = total % 60;
if (h > 0) {
printf "Total Duration: %d hour%s %d minute%s %d second%s\n",
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.
this shell script makes an html table out of a simple 2 col csv
#!/bin/sh
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
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
