linux. how to get images from a (short) video

You can use this code:

ffmpeg -i [nameofthevideo] -r 10 -f image2 image-%3d.jpeg

where 10 after -r is the number of images per second. So you can change it, according to your needs.

linux: keep open the terminal

you can add at the end of your command ;bash
for example:
rclone sync mega:ebooks /mnt/zippati/ebooks/ebooks/ -l -v ;bash

I'm very disappointed by Midori and Epiphany: too minimalist.

libreoffice via snap: not a good idea

Discover let you install the latest LibreOffice release, but:
  • it is very much slower than a no-snap realease
  • no mysql-connectr available
Not a good idea!
So, I removed it: sudo snap remove libreoffice.

rclone and symlinks: a good news

with -l you can copy (i.g. on Mega) your symlinks (as a file with .rclonelink as extension).
When you will sync from remote, that symlink will be created in your local system as symlink.

groups in nextcloud

Nextcloud is a very interesting, open source online platform. With /e/ you have a cloud of 5 free Gb with calendar, contacts and tasks shareable between PC and smartphone.
1) First of all you should export your data (calendar, tasks, contacts) from Google; a problem arises with contacts because Google export your contacts in a vcf file without groups.
2) So you have to import your contacts from vcf google file in nextcloud and re-create groups, which this time could be saved in a vcf file with groups (as categories).
3) To see your contacts and groups you have to use DAVx5 and in account settings - > cardDAV -> group organization you have to choose as in the following image:

not [ ] groups are separated vcards
but [x] groups are per-contact categories
4) This way you will be able to see your contacts and groups in your phone app (or in whatever other app).
