+==== Leading zeros v bc ====
+"bc" zahazuje 0 na zacatku desetinnych cisel, protoze americani maji vseobecne s cislama problem (a neexistuje ani zadny prepinac ktery by to zapnul)
+<code>echo "5*0.1" | bc
+.5
+</code>
+Nastesti co nedokaze basic calculator, dokaze sed... Fix do .bashrc:
+<code>alias bc="bc | sed -e 's/^\./0./g' -e 's/^-\./-0./g'"</code>
 ==== TODO ====
+===== Upgrade Ascii -> Beowulf =====
+==== Strange behavior of touchpad and broken scrolling ====
+X11 migrated from evdev to libinput. Lets go back to the working method...
+<code bash>
+apt-get purge xserver-xorg-input-libinput
+apt-get install xserver-xorg-input-evdev
+</code>
+==== Release.pgp unsupported binary format ====
+When apt-get update says ^^, it means that just some junk is left in /var/lib/apt/lists ...
+<code bash>
+# rm -rfv /var/lib/apt/lists/*
+</code>
+==== ALSA ====
+Well, audio output gets fucked up completely, since "alsa" command is not provided anymore by any package...
+<code bash>
+apt-get purge alsa* pulseaudio* # Na trisky nehled
+shutdown -r now
+apt-get install alsa-utils libasound2 libasound2-data volumeicon-alsa
+shutdown -r now
+</code>
+So "aplay -l", note proper device you want to use and disable the other ones in /etc/modprobe.d/alsafucked.conf
+<code>
+options snd-hda-intel index=HUGE_INTEGER_DEFINITELY_NOT_0,0
+</code>
+Restart again... a v "alsamixer" nastav co je potreba. Restart again and it works (or GOTO 1)
