An aqaintance in NYC made a picture of the star sky and I was dying to
know what
constellation
it was he made a picture of. So after checking
a few constellations it didn't match I left it. Today I took a look at
my astronomy calendar and there was this constellation that I was looking
for. It's called the
Winter Triangle/Hexagon
and has the stars
Sirius
and
Aldebaran
in it, my aqaintance only got half of it but I was able to
reconstruct it with the gimp picture editor. Then I was able to match
the
Gemini constellation
, that was real cool. Looking through the program
Xephem, it pointed out that there was another star between
Betelgeuse and
Aldebaran called
Bellatrix,
see if you can make it out. It's visible.
Also the star labelled
Pollux is at the
end of the line not the star
immediately next to the label, that's
Castor. Anyhow
this is the original picture
and this
here is the
edited picture.
PS: researching a bit further I found the centroid of the Winter Triangle
called Monoceros constellation
. According to William Herschel it is "one of the most beautiful sights in
the heavens".
PSS: I was having so much fun, I mapped most of the
star sky
in the image, except of course Orions belt which should be straight
forward. Here is
another one with
one frame deleted and the rest merged.

Hackepedia, making hyperlinks
January 8th, 2010
I've written a script to cross reference more articles in my
hackepedia
backups. Here is the script, don't use it unless you understand it.
#!/bin/bash
cat /dev/null > list
for i in *.html; do
echo $i >> list
done
for i in *.html ; do
echo working on file $i
awk '
BEGIN { while (getline < "list") list[$0] = $0; }
{ for (i = 1; i <= NF; i++) {
for (j in list) {
keyword=sprintf("%s.html", $i);
if (keyword != ARGV[ARGC - 1] && j == keyword) {
save = i;
$i = sprintf("<a href=\"%s\">%s</a>", j, $save);
}
}
}
print;
}' $i > new/$i
done

Congratulations Wikipedia
January 7th, 2010
On November 13th or so of last year I donated five euros to
Wikipedia.
Well the
fundraiser
is over. They raised over 8 million dollars from more than
230,000 doners. The average donation was about 35 dollars which I'll have to
keep in mind for next years donation as someone picked up my tab so to speak.
So, congratulations Wikipedia, you're the best!

New Project: cryologd
January 6th, 2010
For the last few days I've been hacking away at a new program. Well, three
actually. It's called cryologd and can be found at sourceforge,
here (don't worry I didn't
style that page, sourceforge, did).
So what's it do? It encrypts log files and doesn't write the private key
(needed for decryption) to disk. This is good if your filesystem is subject
to snooping. It uses routines I wrote for natally (and improves on them)
which is good because every project I write I do it to build on top of them.
Let me give you an example. cryologd and natally encrypt their communications.
But at some ISP they don't encrypt and all their credit cards can be read
through the wire. I can now get a job perhaps implementing the crypto at the
ISP, it's easier on me because I've already written this. Anyhow I wish
about the job, but you never know.

2009, a look back
December 23rd, 2009
I saw a lot of people already writing about this year so I'm going to sum up
a few things that I did technically this year.
Jan 3rd, became user of sixxs.net, PJP4-SIXXS handle.
Jan 16th, first article of this blog, with a more technical side than before.
Feb 1st, first sixxs IPv6 tunnel to my static IP which I also obtained then.
May 21st, OpenBSD patch sent to OpenBSD, system/6149
Jun 8th, first initial commit of natally, natally.sourceforge.net.
Jun 9th, transfer of centroid.eu from intergenia to joker.com, who doesn't yet
support v6 glue to .eu domains.
Jun 14th, 30 day trial of QNX, nice that they have pf(4).
Nov 17th, purchase of vmware workstation 7.
Nov 17+ change from redhat linux to ubuntu on uranus.centroid.eu
Nov 17+ purchase of windows 7 HE.
And that was some of the highlights this year. Natally works for me somewhat
today and there was a few bugfixes to wildcarddnsd as well. I also purchased
2 GB of RAM, 1 250 GB harddrive and 1 DVD drive, all not exceeding 180 euros.
My grandmother also died this year leaving me with an inheritance of a bit of
money, but not much. I may purchase a new computer in 2010.

Solstice approaching fast
December 12th, 2009
The Solstice is here in
nine days (on the 21st). What is this? It's when the sun is at it's lowest
point (at high noon) in the northern hemisphere, also called the winter
solstice. Because our earth is tilted and the tilt in winter favours the
southern hemisphere it is the summer solstice there.
