[2013-06-28] python tell

Maybe you think that both examples would produce the same output, but the tell of the filehandler will give you a wrong output in the first version. This version is a bit faster but in this case also a bit inaccurate.

infh = open("bigfile")
print infh.tell()
for line in infh:
    # ...
    print infh.tell()
    line = infh.readline()
infh = open("bigfile")
print infh.tell()
line = infh.readline()         
while len(line) > 0:
    # ...
    print infh.tell()
    line = infh.readline()

[2013-06-28] xmacro on Ubuntu

Install it with:

sudo apt-get install xmacro

Record the macro:

xmacrorec2 > yourfile.txt

Now record your keystrokes and mouse movements, to end it just hit Esc.

To play it back, just run it using the text file like so:

xmacroplay "$DISPLAY" < yourfile.txt

Tip: In my case this wasn't enough because the replay was too fast. I just opend the txt file with an text editor and added some of these Lines:

Delay 1

Now it works like a charm :)

[2013-03-22] China nutzt Ubuntu

So cool das auch sein mag, aber wenn China jetzt Ubuntu as Standard nehmen, dann wird die USA viel Geld in die Hand nehmen um im Cyberwar diese Rechner anzugreifen. Je nach dem wer Tronjaner für solche Systeme baut, verkauft diese dann auch an Staaten die damit Ihrer Bevölkerung auflauern. Das wars dann mit der Zuversicht, mit Linux vom Staatstrojaner sicher zu sein :(
