css :hover on a mobile device

There lots of java-scripts to allow an effect such as mouse over on a mobile device (that is without mouse), but there is also a very, very simple solution: to use :active instead of :hover, as in the following example:

@media screen and (max-width: 580px) {
  .tooltip:active .tooltiptext {
  visibility: visible;
  opacity: 1;
}
}

while in desktop screen you can keep
.tooltip:hover .tooltiptext {
  visibility: visible;
  opacity: 1;
}

connecting android to samba in Linux

You must add in smb.conf (in /etc/samba), at [global] section and at “allow hosts =” row, the android device IP, otherwise you won’t be able to connect it to PC samba network.

Then you can use several android apps, like X-plore (G-Play, commercial, but good) or Material File Manager (F-Droid, open source, quite spartan, but fast and reliable), to set the samba connection with your PC and view the files shared on your PC.

Provided, obviously, that PC and android device are both connected at the same local network.

speech to text in Linux con KDE connect

Per usare della potenza di Google (speech synthesizer), si può usare KDE connect e il controllo remoto che questi permette da smartphone a PC:

1.attivare KDE connect anche sul PC,
2.da smartphone aprire la app KDE connect e scegliere “impulso remoto”,
3. scegliere come tastiera “Google digitazione digitale”,
4.
Parlare nello smartphone e così si vedrà il testo apparire sul PC, nel
programma focalizzato e nel punto in cui è posizionato il cursore.

NB
Può darsi che qualche volta sbagli gli accenti, in questo caso chiudete e riaprite Google digitazione digitale.

android 9

Trovare il modo per passare a Google digitazione vocale  non è facile: occorre cliccare sulla minuscola tastierina in basso a destra:

no root uninstall system app in android

1) From smartphone enable debug USB (settings -> developer options or something similar);
2) enable MTP mode
3) istall and start adb  (adb start-server).
4) search for exact name of the apps you want to remove (i.g. Facebook is “com.facebook.katana”).
5) in (linux) terminal do this command: adb shell pm uninstall  –user 0 [appname]

It works!

As an example I made this bash file

#!/bin/sh
adb start-server
adb shell pm uninstall –user 0 com.facebook.katana
adb shell pm uninstall –user 0 com.facebook.orca
adb shell pm uninstall –user 0 com.asus.ephotoburst
adb shell pm uninstall –user 0 com.asus.task
adb shell pm uninstall –user 0 com.asus.gallery
adb shell pm uninstall –user 0 com.asus.microfilm
adb shell pm uninstall –user 0 com.asus.kidslauncher
adb shell pm uninstall –user 0 com.asus.fmradio
adb shell pm uninstall –user 0 com.asus.taskwidget
adb shell pm uninstall –user 0 com.google.android.apps.photos
adb shell pm uninstall –user 0 com.google.android.gm
adb shell pm uninstall –user 0 com.google.android.videos
adb shell pm uninstall –user 0 com.google.android.music
adb shell pm uninstall –user 0 com.google.android.talk
adb shell pm uninstall –user 0 com.google.android.youtube
adb kill-server
