Here is a math problem. Get out your old Trigonometry notes and solve the
following. A satellite (Galaxy 15 for illustration purposes) is 35,779
kilometers above the surface of the earth in Geostationary orbit. Given
that the earth has a radius of 6371 kilometers find out what the angle from
the ground to the satellite is given that someone stands at 49 degrees north.
Here is a picture:
Line ACB is perpendicular to line EC (6371 kilometers). Line EBD is
6371 kilometers + 35,779 kilometers, so 42150 kilometers. What we're looking
for solving is angle BCD.

I shoulda done this a long time ago but I finally got some money in my
paypal account and I donated 10 dollars to the FreeBSD Foundation.
I hope they can use it wisely.

I just ordered 2 books from Amazon.de. One is Pro DNS and Bind from
Ron Aitchison and the other is called "DNSSEC" I'm unsure of the author.
The latter is a compilation of RFC's and other material related to DNSSEC,
which I want to use in my implementation of wildcarddnsd. Hopefully the
books will help me understand DNSSEC better so that I can implement this
in the authoritative server side soon.

I should have done this a long time ago but I just released the file
wildcarddnsd-beta5p4.tgz to sourceforge, this has a fix that makes the
tcp and udp interaction on the server more reliable. The download is
here
and the branch for BETA_5STABLE is here. If you
get TCP requests to a running wildcarddnsd you really want to get this.
In other news, I'm delighted to say that people from Indonesia are the top
downloaders of wildcarddnsd according to the stats at sourceforge.net. Thank
you! Next are Indians and Russians in the top three. Thanks to you too. I
noticed a lot of asians are interested in wildcarddnsd, which is cool.
As for BETA_6 it will probably take until next year. BETA_6 will have
recursing and caching. It has it in -current now but it's broken somewhat
and needs a good debugging.

OpenSMTPd the OpenBSD mail daemon that is in the works, had a call for testers
on the new DNS code that the daemon is using. Due to my work with wildcarddnsd
I'm somewhat familiar with DNS and was able to make a
contribution.
Not in the form of patches which would have been nice but questioning whether
the opensmtpd dns code withstood a certain scenario. It turns out given a
second opinion that I was
"totally right". This really made me happy and the
opensmtpd is more robust as a result. This is why open source is so good
because people can read the code and spot errors before they write exploit
code to stress test an application (black box). If I had to write the exploit
code it would have taken way more time than what it took up.
