Reset Resolution of X Server after Program Crash

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.

Ein interessanter Artikel über die Dummheit und Faulheit heutiger Westweiber:

Tacheles! Wisst ihr, ich frage mich in der letzten Zeit, warum wir immer noch alle glauben, wir werden einmal 100 Jahre alt!

Ich bin froh, dass ich eine Frau habe, welche noch selber kocht, und welche diese Kunst auch noch den Kindern beibringt. Im Westen findet man das kaum noch, und in den USA wird heute schon mehr Geld für Medikamente ausgegeben als für gesundes Essen.

Bitcoins Today

The last few days I was reading a bit anout bitcoins and learned a few things about them, though i still did not read the paper. More informative than bitcoin.org are the bitcoin wiki and howtobitcoin.info.

I thought transactions are free, but they are not (only sometimes). Bitcoinfees.com describes these fees very good.

There seem to be plans to create a bitcoin fund. This will lead to a more widespread use of bitcoins. A good thing for the network.

As long as nobody gains access to more than 50% computing power. An interesting read is here. The wiki contains a list of (known) weaknesses of bitcoins.

After reading a bit I thought “let’s give it a try” and installed the standard client, bitcoin-qt. After starting it I found out that it downloads the whole blockchain, the whole history of all bitcoin transactions ever made, from the net. It showed far more than 100 weeks remaining and for every week downloaded it became slower. I thought there must be a faster way and found this forum post about a bootstrap file. I downloaded these 2.7GB (zipped) and let bitcoin-qt import it. This import was pretty fast, unfortunately still 28 weeks were remaining. I waited almost one day to see it reaching week 21 and the wallet grew to a size of about 6GB. So I gave up. This is unacceptable.

Fortunately there are other clients which do not need to download anything. Or if they do download something it is not noticable. So now I am using Electrum.

The good thing of all this is, I have now a nice bitcoin address to accept donations:

Marble Cake

I found some recipees for marble cake on the web. After filtering out the ones with ingredients not available (or difficult to organize) here in india I settled for the following recipee. I reduced the amount of maida since I don’t want a granite cake ;) and replaced butter with margarine:

Beep Off!

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!!!
blacklist pcspkr
EOF

Also just remove the kernel module to get the same effect without reboot:

rmmod pcspkr

Aaah, much better now :)
