Tip for all Colombia vacationers and expats who have a Visa Credit or Debit card. Only at the following Colombian banks you can withdraw cash for free: 1. BBVA 2. CAJA SOCIAL, 3. DAVIVIENDA. All others charge fees at the ATM. And additionally at DAVIVIENDA you have to DECLINE the exchange rate on the left side of the screen suggested. (May not be current info)

Doesn't work with PulseAudio, although Linux now uses PulseAudio by default. It wants Alsa, but it can be made to work with Jack.

SD CARD size

Raspberry Pi 4 is the only model of Raspberry Pi that can support a 128 GB SD card. But SD cards of size 64 GB require FAT32 formatting to make it bootable for Raspberry Pi. The SD cards higher than 64GB needs exFAT system, which Raspberry Pi doesn't support.

For a 128 GB SD card, you have to format the drive through exFAT or NTFS file system as both file system now supports Raspberry Pi 4. You can only have these two options left for an SD card storage larger than 32GB.

**DISPLAY HAT MINI **

(This didn't work, but I don't think it can be set up maybe as main display, or there is a way but you have to ‘build’ You must enable:

• spi: sudo raspi-config nonint do_spi 0
• Just run pip3 install displayhatmini

DISPLAY: 3.5 LCD

• https://www.youtube.com/watch?v=Fj3wq98pd20
• just copy and paste his code

rPI 3.5 inch screen

• After booting into Raspbian (or whatever) do:
• sudo rm -rf LCD-show
• git clone https://github.com/goodtft/LCD-show.git
• chmod -R 755 LCD-show
• cd LCD-show/
• sudo ./LCD35-show

To get your HDMI monitor back:

• chmod -R 755 LCD-show
• cd LCD-show/

virt-manager VMs in Tails https://tails.boum.org/doc/advanced_topics/virtualization/virt-manager/index.en.html

Note: Can't use ‘persistent’ on the first install (from the DL). Have to use that DL and boot it and then install Tails from that to another Tails USB.

• tails.boum.org
• is the official site
• (note, 32bit or 64bit. New versions do not have 32 bit (most recent 2.12 I think)

you put it on a USB, but that one won't allow Persistent. You have to use that Tails USB OS to make another Tails USB from it. ... Use ‘Tails installer’ and write tails to another USB/SSD. Now use that new USB Tails (don't use the original one) and boot it, and you can ‘configure persistent’ on that one. Should work. (Persistence is adding a storage volume which is/can be added to future boots.)

Without Persistence, Tails is such that it removes the fingerprint of the user (from browsing interface). The internet can see you use Tails perhaps but not who the user is. (It can't see browser configuraiton, screen resolution, what drivers are installed, in addition to the things most people think of ie MAC address, IP address, analytics).

Note: Persistence is NOT invisible. You can see it when you boot on that USB.

AppImages in Tails

• first, put in ‘persistent’ folder
• then, make executable

QUESTIONS

• How does Tails clear RAM?
• Other Samplerbox?

Improvements for Tails

• should ALWAYS show “pw for persist. If you have not set up Persistent, ignore this"
• 2nd pw for delete

Add languages

• https://tails.boum.org/doc/first_steps/additional_software/index.en.html
• for LibreOffice: libreoffice-l10n-lang
• for Thunderbird: thunderbird-l10n-lang
• es for Spanish

Starting point (doing it manually):.

After installing ImageMagick software sudo apt-get install imagemagick -y on a Debian-based distro, you can just use Terminal and your file manager.

Put  some image files in a folder. Open Terminal in that folder. Use 'magick convert' (which belongs to the ImageMagick software you installed) to resize, rename, and reformat the image files.

Example:

I placed 5 pngs into ~/Desktop/ImageFrom, altogether they weight 2mb. (I also have a folder desktop/ImageTo.) I open Terminal in ~/Desktop/ImageFrom and do mogrify:

mogrify -path ~/Desktop/ImageTo -format jpg -resize 1000x1000 *

This puts versions of all my pngs into my other folder, but they are now jpegs with the longest edge being 500px. They now weigh 225kb altogether.

Here ends the 'Starting point' part.
