Life in Ireland
12th November 2004

Life is hard in Ireland, it's far more expensive than it was in Israel, we get by but we are cutting a lot of corners and are way down in our life standards (smaller apartment, far less restaurants) and it rains here almost everyday. In Israel it rained "almost" every day, every day (in the winter) it would almost rain, but wouldn't.

At least I'm working on the Linux Kernel and am allowed and expected to release my work to the wide public, it is available at http://hamilton.ie/net/, I'm currently working to improve the patches, after that I need to port it to 2.6.9 (or whatever it will be at the time) and submit it to the LKML for the criticism.

I'm also trying to gather my will and do some free software work, I've got a good word from a user of AutoFW so I decided to look at it again and rewrite it in C, but now I need to access netlink directly (in Python I just run 'ip monitor link addr' and parse the output), I started to use libnl but I found that it doesn't support address types and doesn't support firewall netlink so I first need to get it to know these. Lots of work.

There was also a sign of life on the websec mailing lists which reminds me that there are some overdue issues with it.

Learning Chinese
12th November 2004

I've started to learn Chinese thanks to a friend from Singapore, I've learned a few sentences, wrote them in Abiword and printed it so I can learn it offline.

I've learned to write my name in Chinese, it is written 巴湖 which is pronounced Ba-Hu, which is close but not exact, but then most languages won't be able to say my name correctly anyway.

It was a lot of pain to get chinese working, I installed tons of packages, I tried uim first but couldn't get it to work so I switched to scim. It now works pretty well, but sometimes my system gets confused in what input state it is. I can now write English, Hebrew and Chinese on my Linux machine.

I now need to find a program to teach me the alphabet, I found several programs for Gnome but they either don't work, crash or don't compile. I will turn my attention to KDE and otherwise now.

Update: She left back home and I'm left with no teacher. Bummer.

FlexiFW
23rd November 2004

I've been distracted from AutoFW and libnl by an old idea of mine for firewall implementation, a project which is currently nameless is now working on my machine. Thanks to <whomever> in the netfilter team that thought to create the QUEUE target and libipq, it now works in user mode under the temporary name of umfw (user-mode firewall).

The first stage was to create a simple interpreter firewall, the second stage was to create a compiled firewall (compile the firewall to C and then compile to object code), the next stage is to make it work in the kernel as a target for a netfilter rule and a shared object for netfilter to be able to add this rule. Third stage is now in progress.
