Goodbye, World (Celebrating the life of Dennis Ritchie)

October 13th, 2011

I saw a similar posting on Slashdot...

int
main(void)
{
	printf("Goodbye, World.\n");
	exit(0);
}
I bought the book "The ANSI C Programming Language" (second edition) three times in my life. One is in the hands of a stranger who I gave this book at the GTABUG BSD Usergroup meet in Toronto. But this article is not about the book but rather the author of this book who recently died. Rest in Peace Dennis Ritchie, and may everyone who was touched by your wonderful creations celebrate your life! Mourn death, but celebrate life. Thanks for making me understand (somewhat)!

Photos from EuroBSDCon 2011

October 10th, 2011

I got back home earlier today from the hotel in Maarssen. Here is some photos that I made of people and the venue. Enjoy. Email me if you are in these photos and want them removed.

Photos from EuroBSDCon 2011.

Unfortunately many photos turned out blurry and distorted, I decided not to put those ones up. Maybe I need a new camera.

My Business Card

October 4th, 2011

I got 100 business cards made for EuroBSDCon. I got the idea at BSDCon 2000 where I got at least 10 or so cards from 10 people. Here is how mine looks like:

I'm getting on a train tomorrow so this should be the last blog entry before October 10th. I'm not going to have guaranteed 'net but if I do I have an OTP skey system set up that allows me to reach an account on my DSL.

I miss you!

October 2nd, 2011

The blackbird (Turdus merula) here has disappeared. I can't see them any more and someone told me they had a mass dying. Some virus perhaps. Here is a picture I took of a blackbird in Schweinfurt a few years ago during winter feeding on my parents porch. They were cheerful birds always singing very loud and getting on someones nerve while I was programming. But now that it's all silent, I kinda miss the dang things. May you have better fares in the place you are now!

Weird BIND9 observance

September 29th, 2011

Ever since I put in IXFR support in Wildcarddnsd I have been watching the logs and I have a very weird problem. Basically all zones except one DON'T get pulled. What's weird about this is that I'd expect either all zones get pulled on a regular basis or none like all but one are doing right now. When I restarted bind9 on goldflipper.net it pulled a zone update for centroid.eu and ever since has been pulling it on a regular basis. The SOA is the same on both goldflipper.net and uranus.centroid.eu:

$ dig +short soa centroid.eu @uranus.centroid.eu
uranus.centroid.eu. pjp.centroid.eu. 1316729113 3600 1800 1209600 86400
$ dig +short soa centroid.eu @ipv4.goldflipper.net
uranus.centroid.eu. pjp.centroid.eu. 1316729113 3600 1800 1209600 86400
Below is roughly an 80 line log of wildcarddnsd AXFR operations to show you what I mean.

Bye Bye seti@home, Hello Rosetta@home

September 28th, 2011

I've been doing seti@home on and off before it was a BOINC task. However I'm getting weary of waiting for news of SETI discoveries. It's time to do something new. Out goes seti@home and in goes Rosetta@home. Rosetta@home is similar to Docking@home which I also participate in. It's really time to dedicate my computer to humans instead of aliens, we're in greater need (in our ignorance). If you're interested in what my BOINC stats are, here they are. I'm in spot 142,597 out of 2.2 million and dropping by 19 daily. That's OK though I'm not complaining.

Wildcarddnsd Handbook

September 28th, 2011

I've created a small Handbook for the design and implementation of the Wildcarddnsd program. It may be interesting to some and you could learn something from it. I'm thinking of one day making this into a magicpoint presentation for speaking somewhere.

Well the AXFR code is in the wild now (:P). Here is a commit message that should be very informative on what was changed.

Going to EuroBSDCon for sure

September 18th, 2011

Well I just paid the registration including 1 tutorial. I'll be attending the "Building the network you need with PF, the OpenBSD packet filter" tutorial by Peter N. M. Hansteen. I'm hoping to pick up some nifty tricks and get more familiar with the packet filter in general. Then I'll also attend the conference and social event. I enter Amsterdam on the 5th of October and then take the train to Maarssen on the 6th. On the 7th is the tutorial and 8th and 9th are the conference, on the 10th I'm going back to Germany by train and on the 11th I go back to work. Well I wish I could say see you there, but what the hell. See you there.
