Centroid.EU Blog(this blog is mostly encrypted - adults only)

I couldn't deliver to gmail anymore today. I think my parents spammed some
day. Or someone with my identity from another server? After I had installed
an spf record in the DNS system (TXT RR spf1) gmail would take my mail on
again. This is what my SPF record looks like from the dns query program dig:
;; ANSWER SECTION:
centroid.eu. 84994 IN TXT \
"v=spf1 ip4:126.96.36.199 ip4:188.8.131.52 ip4:184.108.40.206 ip6:2a01:4f8:d13:1980::/64 ~all"
Any other than these IPv4 and IPv6 networks will get a softfail from now on.
Probably a 4XX reply and no mail delivered. It's funny that gmail requires
spf records now?

Not long after the YACC file was finished I have given the configuration file
options that were only in the command line before. So I have moved these
over. Here a small excerpt from the commit log message:
-b option == bind IP;
-i option == interface "lo0";
-n option == fork 2;
-p option == port 10034;
-l option == log;
This took me one hours to program approximately. The yacc configuration is

Yesterday before going to bed I committed my YACC parser for wildcarddnsd.
Wildcarddnsd is my authoritative DNS Server that I programmed, it had a
sloppy C based parse program before that. The YACC parser is great, I took
parts from OpenSMTPD project and have thus added their license to the top of
it (with my name added of course). The YACC parsing was mostly done by
myself and the lex & yacc O'Reilly book that I had for at least a decade now.
It should be noted that it took me 1 year almost to write this YACC file, I
didn't work hard on it, but the logic of YACC did stall me at times.
So what's next for wildcarddnsd? I hope to be committing more YACC in the
following months before the 0.9 BETA (should be in november). What we need
is a way to put commandline options into the configfile, which is really
simple now. Thanks for reading! :-) I'm pretty happy.

I have ordered my new computer today, this computer I'll call mercury.
- Intel Xeon E3-1275v3 CPU
- 4 x 8GB Kingston RAM
- ASUS Z87-WS motherboard
- SSD Intel 530 180 GB
- Bluray DVD LG
- Thermaltake 630W PS
- Extra CPU cooler
- Fractal Design 3000 towercase
- Mouse and Keyboard
It came to 1429 euros, which I had budgetted above.

A new 0-day vulnerability is making the rounds
The vulnerability works on both clients (Mozilla Firefox for instance) and
servers (mail, web or anything that uses SSL/TLS with heartbeats). I saw
some strangeness in my OpenBSD laptop on console as I was shutting it down,
but luckily I have sandboxed the firefox to another user so it appeared to me
like a permission denied error. It's possible someone wanted to read my
$HOME/.ssh/id_rsa* files, this is why I implemented the running as another
user in the first place.
So as mitigation I have applied patches to my OpenBSD workstations. Also I
have turned off opensmtpd on my panama VPS which does a backup MX function.
Until I have that fixed (possibly with help of the hoster) it won't be turned
on again. All other versions of OpenSSL that I use are not affected.

In nature there is always threats. I recently watched a documentary this
weekend about the
Great Dusky Swift which hides and sleeps behind waterfalls. This is a
natural safe haven for the bird species, pretty ingenious.
In the mid 1990's I played a online BBS game called tradewars, where players
trade, steal, and destroy each other. It was ANSI based and I even later
attempted at creating a helper program for this at
twh.centroid.eu, the helper sucks but
what my favourite strategy was in that game was to check if a robot planet
named ferrengal was cutting off the entrance to a tunnel sector. If yes then
I'd shoot a photon torpedo into ferrengal to stun it and quickly move past it
into this tunnel. Here I could build my home planets and have a safe haven
to sleep. It was much like the Great Dusky Swift of south america chosing to
sleep behind a waterfall.
I wonder what the future holds, are wormholes possible? And if so can one
create a wormhole that is a sock? ie. it has no end? If that were possible
then hiding in such a stretch of space-time would be like putting on a cloak.
Spaceships that may come from other galaxies to study us may hide inside these
"socks" and not worry about being seen at all. It is almost like hiding
behind a waterfall... :-) in space.

I turned the heat off here at home, so I'm hoping the weather doesn't get
cold again. Last year I spent over 8000 KWh's and 80% for heating. Not ideal
but perhaps the price in electricity will drop with all these "green" wind
turbines and solar panels. Next year I'll spend less money on electricity
as I'll heat my home a little less, it was too warm occasionally in my
apartment last year.
In other news the local nuclear power plant Grafenrheinfeld has announced that
it will shut its operation in May 2015. The reason they are saying this is
that it is unable to compete on the energy market and it's not worth it any
more. I think this is good news. I've been against this nuclear power
plant almost since it began operation,

Although belated I'd like to make you aware that we surpassed the blogs 5th
Anniversary on January 16th, 2014. Although the articles are missing until
May 2009, they were once there. I had expired these but kept their article
The blog was always like a public diary to me. I just am not important enough
to write about cool topics that are/aren't directly mine. Oh well. The
history of centroid.eu is longer than even this though, but this is the
longest I had centroid.eu in one piece. It expired once even before that,
but before that I was going through some hard times and the seriousness of the
blog wasn't there. Now it's pretty serious stuff IMO. I like writing in this
blog and I hope to be writing for another 5 years in 2019! See you then!
