Rocket Scientists, why can't this be done?

October 24th, 2011

I was wondering why humans insert rockets in a circular orbit around the earth first and then gun the engines to "escape". First a picture of how it's done currently.

I envision space craft going directly up into the sun toward L1 Lagrange. Basically it's ascending straight up, followed by a coast and then possibly ION engines backed by possible lasers (for energy) from the ground, in order to stay at this Lagrange point.

Basically up there it's like an eagles nest in the mountains. You experience day at all times, see the earth lit all times, and are able to move between other lagrange points with little to no chemical energy. Also accessing the moon from there should be no problem.

German Trojan, some thoughts

October 19th, 2011

This story is circulating. I noticed that the programs being spied on are programs that use encryption and that's probably what the police are out to get at, encryption keys or seeing what someone is doing what they can't see by simply wiretapping the line. I noticed they are interested in skype (which uses encryption). What it comes down to is that there is a frustration out there that the cops want to see through the encryption of end-users that they suspect for whatever reasons. In a way this is a nicer way of peeking through encryption than installing X amounts of supercomputers to crack the encryption used, it's likely also cheaper. The underlying problem of creating a police state is real though. So where do you find a median? We can't turn encryption off as some countries dictate because organized crime will get to us before the cops can protect us, and the losses will be huge. We can't install supercomputers because they suck up too much energy and cost too much. So what can the cops do to track criminals? It's not so easy, why don't you send me your thoughts? Lastly we don't want to put the cops in a position where they can surveil anyone or everyone without a court order.

Did you know you could get BSD Certified?

October 16th, 2011

At EuroBSDCon I met and spoke a bit with Dru Lavigne. She does the BSD Certifications at most major BSD events. All in all a good thing if you live in a place where certifications are important. If I go to EuroBSDCon next year I'll try to do the certification myself. The website is here at bsdcertification.org . I also made a photo of Dru but it turned out very blurred so I can't share that, sorry.

The FreeBSD German Documentation Project

October 15th, 2011

At EuroBSDCon I had the pleasure to speak to Benedict Reuschling who is involved in the german documentation project. They are always looking for more people able to translate from english to german. Here is their website.

Als ich auf EuroBSDCon war hatte ich die Ehre mit Benedict Reuschling zu reden der bei dem FreeBSD Deutschen Dokumentations Projekt arbeitet. Sie suchen immer mehr Leute die Englisch zu Deutsch übersetzen können Hier ist die Webseite des Projektes.

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.

I sent an email to the BIND-users mail list but I think it got stopped by the mail administrator or got dumped to /dev/null.

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.
