Varför finns det stöd för att skriva ryska med svenskt tangentbord i Linux? men inte med finskt, norskt o.s.v.

Detta kan man välja i raspi-config:

Re: A beep that works in Raspbian Stretch

Thanks!

An alternative to above is after

Code: Select all

sudo apt install sox

Code: Select all

raspi-beep2 () { play -n -c 2 synth $2 sin $1 2> /dev/null; }

Code: Select all

raspi-beep2 440 .7 ; raspi-beep2 880 .5
It is slightly louder. The first alternative is built-in.

It is possible to control Minecraft PI Edition using the built-in Scratch 1.4, see this project:
