Google and NASA recently were in the news regarding their shared Quantum
computer. They said that certain operations
yielded a speedup of 100 million times what a classical computer can do.
To put this into perspective. With 1 billion dollars you could buy 100 of
these D-Wave computers which cost 10 million a pop. And those 100 would then
have a distributed speedup of 10 billion times that of 1 classical computer.
All that it leaves to question is .. what algorithms are capable of being
run at that speed? If it's Shor's algorithm I think we can kiss our crypto
safety goodbye. An SSH or TLS session would then be decipherable as it is
an RSA Hybrid.
What was the "black-budget" of the USA again?

Reggae
December 11th, 2015
I purchased the album "Legacy - an acoustic tribute to Peter Tosh", which is
performed mostly by his son, Andrew, I suspect. Because I don't have many
Wailers songs this will be a good addition to my music collection. Reggae
music is wide-spread in spectrum but this goes to the root. Happy listening.

Thinking of getting a third Internet Link
December 7th, 2015
I'm thinking of getting this cable Internet thing in the New Year. The german
Telekom is slow in rolling out their VDSL in town so I'm thinking of going
with RegioNet which is the citys own Internet company. Thinking of 50 Mbit/s.

Trying to run letsencrypt beta
December 5th, 2015
Well I tried to get the free https certificate with letsencrypt tonight:
19 ./letsencrypt-auto certonly --manual --email letsencrypt99@centroid.eu \
--agree-tos -d centroid.eu
id.eu --agree-tos -d centroid.eu <
Updating letsencrypt and virtual environment dependencies.......
Running with virtualenv: sudo /home/pjpxx/.local/share/letsencrypt/bin/letsencrypt\
certonly --manual --email letsencrypt99@centroid.eu --agree-tos -d centroid.eu
We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:
#1) Respect the privacy of others.
#2) Think before you type.
#3) With great power comes great responsibility.
Password:
Ugh no! I will not run this as root. This utility will need a fix for that
before I run this again. Too bad!

Anonymity
December 3rd, 2015
In this article from heise
online (german), politicians cry out about anonymity. In this case they're
right IMO. However I see the problem different. Right now the "end-user" is
given a dynamic IP address which is to "guarantee" them their anonymity. Yet
the provider knows who they are, and google as well as other large networks
who can correlate big data or logins to match someone. Also an end-user today
must use IMAP or POP3 or webmail to a server on the internet to fetch their
mail. Pretend it were different. Pretend everyone was given a static IP.
Everyone now theoretically knows who this person is. Google would not care
because they already knew anyhow, but you may see its market share go down
because they don't guard a secret anymore. Also people would be able to
get their mail via SMTP instead of IMAP/POP3 meaning mail is not stored on a
3rd party server. This is positive. A person with a static IP can run any
services they like and become a server in this sense. This means that someone
can have friends using their computer too, but if any of those friends betray
the trust and invite a police visit, the friendship may be endangered. Who
has taken the blame for things their friends did? I for one did once. But
that was the last time. If you're a known troll for something your friends
did from your computer it'd be very hard to repair that reputation, but that's
the idea behind fixing this anonymity. So let's all be open and have static
IP's is my idea.

What happens when...
December 1st, 2015
I tried to make two zones on two DNSSEC enabled nameservers. One being
io.solarscale.de which is delphinusdnsd and the other americas.centroid.eu,
which is BIND. I was interested how the servers would behave with one signed
zone and one unsigned zone. And the result was staggering. There was almost
no difference between the BIND and the delphinusdnsd. Both however reply
with the DO bit set on the unsigned zone, which is possibly wrong. The
signed zone is swshell.de and the unsigned zone is black.solarscale.de. Well
it was worth the experiment and my code was forgiving.

23 days until the December Solstice
November 29th, 2015
It's 23 more days until we enter winter in the northern hemisphere. The
southern hemisphere enters summer such it is properly called the "december"
solstice and not winter solstice. There is probably other names but I'm
going to stick to december solstice. Its date is december 22, 2015.

10 Years
November 29th, 2015
Today is the 10 year anniversary of delphinusdnsd. DNS to me has always been
appealing, from vanity domain names on IRC to managing DNS as a hostmaster
(system administrator). I wanted a deep understanding of DNS further than
just being a hostmaster so I decided to keep working on this. At first it
was just a stupid little turnkey program, but I got to like it so much that
I continued to put my efforts into it. I'm doing DNSSEC with it now. That's
a major feature. I plan to release the first major release in january 2016
which drifts off the new years date. Oh well, cheers!

10 years Delphinusdnsd in 9 days
November 20th, 2015
It's here in 9 days. The anniversary when I can prove when I checked in the
sources to the then-called wildcarddnsd. 10 years! And my server is like an
arrogant little child still! Nothing like bind which is probably 17 years
old now.

Keeper of the Isis Light
November 18th, 2015
I read this book in grade nine. Also the sequel to it "the guardian of isis". These
have nothing to do with ISIS that we hear about in the news today. These books
were very well written IMO and were good science fiction. Something to dream
about.
