ssh X forwarding on your server

If you have an ubuntu/debian server running and want to run X apps through ssh -X you should "apt-get install xauth" for this to work.

tortoise SVN

In some cases tortoise svn (windows svn client) can't do checkouts of your repository and the following message is displayed:

"Not authorized to open root of edit operation"

Adding the following line to your svnserve.conf solved the problem for me:

"anon-access=none"

convert int to a separate bytes

def intToBytes(self,n, bytecount):
""" returns the binary of integer n, using count number of digits """
str = ""

i=bytecount-1
#8 bit mask
mask = ~(sys.maxint^(pow(2,8)-1))
while i >= 0:
str = str + chr((n>>(i*8))&mask)
i-=1

return str

convert bytes to an integer in python

ran into a situation where i had to convert some bytes to an integer value in python. This func does the trick. The mask is only used to have a counter of the same length counting backwards (hence the negation).
def bytesToInt ( self, bytes ):
""" convert certain amount of bytes to an integer """
size=0
i=0

mask = sys.maxint&(len(bytes)-1)
while i < len(bytes):
size = size|ord(bytes[i])<<((~i)&mask)*8
i+=1

return size
