What a month (2):

Had an exam in stochastic processes. It's amazing how you can take a simple problem as the drunk-person problem(*) and make it into something complicated as markov chain(**), Martingale(***) and finally stochastic intergral(****). I enjoyed the lecturer Prof. Adler quite a lot (he also thought me about probability, where he explained me the Poisson distribution using Wombats). Viva Adler! However, the course was quite unformal (understatement), as we replaced the order of limits, and did other forbidden things (the thing in math that you shouldn't do without proving it's ok to do).

I currently write an exam for my course (computer security), which I hope they'll solve fair and square.

In the Linux front: ladypine took much of the effort of handling Haifux's scheduling, etc. However, she is currently in OLS, so I had to do some things alone. She left a very good scripting environment for re-building our site, but it took me several months to understand how it operates.
It seems that the Israeli public is more and more aware to Linux and FSOS as an alternative, even though many still complain on it's lack of userfriendliness. A nice quote which I heard about it in the last couple of weeks was that - "Linux is userfriendly, but it chooses it friends carefully". I partially agree, but I am aware that most of it (espeically for the end-user) is very friendly nowadays.

Research front: my advisor took part of his sabatical in Paris (ENS), and now that he returns I have three different researchs to show him. The problem is that he also put a lot of effort in other research topics, so he doesn't really have time to sit with me... I have 3 papers at him, waiting for comments (two to be sent to Journal of Cryptology, and one was sent to Asiacript. it was rejected from CRYPTO 2004).
What to do with a fellow researcher who quote your results while abusing them? calling them in the wrong title (rectangular instead of rectangle, etc.)?

Real Life: BUSY!

(*) - a drunken person is put on a line which he moves right and left with equal and same probability (1/2). His movement is consdered symetric random walk. (**) - similar to above but with countable number of states, and each state has probability to move to other states. The probability is independet with the past. (***) - a sequence of random variables X1,...,Xn,... s.t. E[Xn+1|Xn,Xn-1,...X1]=Xn. This is the case in (*), as the expected place of the drunken given that in step n he was at Xn is the same place (as with probability 1/2 he is at Xn +1, and with the same probability is at Xn -1). (****) - just like regular calculus, but with additional difficulty - an integral over a brownian motion - you don't really want to know ... do you?
