Yesterday I stumbled upon a post about free whatsapp softwares. So I thought I give it a try. After some initial troubles and a lot of startpaging I finally got it running.
Today I wanted to dissect a PDF file. Running pdf2ps quickly showed some big lumps of binary data. Looking a bit closer I found out that it is run through the filters ASCII85Decode and LZWDecode. After failing to decode this myself I searched again on the net and found the following blog entry:
So just run the following commands:
qpdf --stream-data=uncompress original.pdf decoded.pdf
pdftops decoded.pdf decoded.ps
Today I played Warzone 2100. In the second mission in the beta camp I gave orders to build defenses, factories and other things. Then I loaded the transporter and started it to get to the missions map. But then the program crashed and left the X server in a pretty low resolution.
Now how do I reset the resolution?
Easy, the following line does the trick:
xrandr -s 1920x1080
You may have to choose the proper resolution for your monitor. Just entering
xrandr without any options shows the available resolutions.
Linux’ beep is much too loud. This is very annoying. I haven’t found a way to turn down the sound. But here is a way to completely switch the beep off (at least on debian):
cat > /etc/modprobe.d/pcspkr-blacklist.conf << EOF
# beep off you beep beep beep!!!
Also just remove the kernel module to get the same effect without reboot:
Aaah, much better now
