link, rather than embed images in odb file

Today I followed this way: link rather than embed the images, so that the odb file can remain of small size.
1. in edit view add a text box in your form and
2. convert it (replace with) to a image control
3. in normal view double click on the new box and select the image, which will not embedded, but linked.

with mysql

If you use a mysql database you can set the field as varchar (at least 150 char) and insert the location, such as http://localhost/your-path/yourfile.jpg.
Then you can add this field as data in the text box (as above).

avoid blur in sddm screen and lock screen

1) login screen

SDDM Breeze 5.13.0 main.qml has:

Code: Select all
        WallpaperFader {
            visible: config.type == “image”
            anchors.fill: parent
            state: loginScreenRoot.uiVisible ? “on” : “off”
            source: wallpaper
            mainStack: mainStack
            footer: footer
            clock: clock
        }

Changing

Code: Select all
visible: config.type == “image”

to

Code: Select all
visible: false

Image

Testing – no blur at here.

2) lock screen

 You have to change LockScreenUi.qml in /usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/lockscreen as well, adding the same row:

visible: false

in  WallPaperFader

videochiamate (whatsapp e simli) su linux

Sconsigliatissimo whatdesk (via snap): non fa video né audio chiamate; fa le stesse cose di whatsappweb, solo consumando molto più spazio e memoria.

Un po’ meglio Franz, anche come appimage, che però fa videochiamate solo con Skype, non con Whatsapp o Icq (anche lì: fa lo stesso delle corrispondenti pagine web).

programmare (schedule) un evento

Si può usare, in Linux, crontab. Così:

1. Create uno script. Ad esempio, se volete che vi sia ricordato di bere:

#!/bin/sh

kdeconnect-cli –ping-msg “ricordati di bere!” -d d30fdc9ed6e2bf56
play /mnt/musica/avviso.wav &&
zenity –info –display=:0.0
    –text=”Time is $(date +%Hh%M)nnricordati di bere.”
    –title=”drink time”

2. creare un evento crontab
    a. in un terminale digitale crontab -e
    b. digitare, ad esempio in nano, 30 8-11,15-18 * * * /path/to/script

Per vedere se il sistema ha salvato correttamente il proprio file di cron, digitare il seguente comando: 
crontab -l
 

3. Per avere anche sullo smartphone l’avviso dovete avere kdeconnect
 
Fatto!
