In the north sea, north of Germany, there lies not far from Norway the
Norwegian Trench. It is as deep as 700 meters. This is the only point
where the north sea is 700 meters so it makes sense that the norwegian
trench is the intended place for these "power" spheres that are pumped
storage facilities, as the Fraunhofer Institute for Wind Energy and
Energy Systems Engineering has envisioned. So I looked a little at this.
I tilted my head a little and thought, that would make an incredible
underwater replenishing station for submarines. If enough power spheres are
made it won't be immediately noticeable that they would repurpose some to be
hydrogen storage containers. Hydrogen? What for? Well if you haven't
heard by now Type 212 submarines of the German Navy use hydrogen to get their
power. And did Norway have the same subs? Well yes. They just ordered a
batch of four from Germany last month. So there is the operators of the
replenishing facility. Only problem is: Can Type 212 subs dive to 700 meters?
And I checked on wikipedia and the answer is, yes. So perhaps there is a
military mandate as well as the economic mandate for these power spheres.
I gotta admit I really used my imagination to the fullest here, and used
wikipedia to back up hypotheses. Would be something right? If there was a
submarine base just off Bergen? BTW Bergen is strategic, in all my games
of the submarine simulation "Red Storm Rising" as a youth it was the Soviets
that would capture Bergen first and a submarine had to stop the landing
crafts. It was usually that the Soviets succeeded in taking most of Norway
and Germany, so if that's in simulations it must have been a fear. Red Storm
Rising was a game that probably had navy advisors as common knowledge would
have never been enough to make that game as real as it is.

I know I have a lot of these but I really need one over in Canada. It's
a $10/mo digital ocean VPS in Toronto. I hope it sees use.

The car I intend to buy
March 5th, 2017
I've not had a car since 1993, so close to 25 years. Back then I had a 1987
Dodge Shadow (turbo). And after moving to a metropolitan area of 4 million or
so inhabitants (rough estimate), I preferred taking the subway, bus, or even
go about by bicycle. Since I've been working at a job in the VOIP industry for
close to 7 years now, I've saved up my money. And I'm finally wanting to
spend that money again. First I wanted to invest it into a business, but that
is harder than you think. I'd rather get a car now and i've set my eyes on an
electric car. Particularily the
Renault Zoe. I've fallen in love with that little car, even though I
haven't driven it yet. Should be interesting taking my first ride in it.
With the car I'm going to get a few other gadgets. For example a cell phone.
Yep I haven't had a cellphone for close to 15 years now. I'll need it to
call emergency services when my car has problems. Also I do want to persue
astronomy more and perhaps get a Newton or such scope. With a car I can put
it all in the trunk and drive to locations where it's dark enough. I don't
know what it is but it seems I've been granted a new stage in life from a very
skimpish lifestyle to being normal. I'm just soaking it in, and spending the
money I aquired over the years. Should be good.

When I fell into the EU's lap, or, what's wrong with you?
March 5th, 2017
When I left West Germany as a child to live in Canada for a decade and a half,
I left not knowing about the EU. I retained a german passport however and
returned to now-united Germany in 2002. In fact in 2002 I don't remember
using the DM anymore and it was the Euro. The EU was big in population.
Real big. Bigger than the USA, and I had to get to terms with that, that
I'm now living in a 500 lbs Gorilla superstate.
Sooner or later I began to like what the EU allowed me to do. I took on
trips to France and the Netherlands in the next decade, without needing to
go to customs or money exchanges, and it was a great feeling. It was like
something directed me into place that I was a European now and not just a
German citizen.
I also considered taking a train to London via the Channel Tunnel right from
home and considered the route on bahn.de. Unfortunately with Brexit I'll have
to delay that London trip a little bit. I don't feel comfortable with customs
at all. We should live in a borderless world. Really! And we should become
world citizens. But it will have to be European as a first step.
Don't get me wrong. I too have had my share of hard times being unemployed
for 7 years at a length, in Europe. It may seem sometimes that Europe is not
able to compete with itself for jobs. But at the same time we're getting
richer as a community so the money goes somewhere. I'd say look not at
globalization as the culprit but the un-equal structures that evolved before
states united into the EU.
We have to make the EU great. And not again. Because we were never great.
We're in our infancy and the six founding members of the EU, of which Germany
(West) is a part of, needn't try to break up this once in a lifetime
opportunity. We are the core, we should set the examples for the rest of the
EU.
In the past I have seen an unseen hand of the Internet try to downgrade the
EU. Try to sever our bonds from far. With me that doesn't work however I
see much to be desired for when it comes to the number of crisis situtations
that we have to endure. I'd like to see us become closer tied in the future.
That means not just internal affaires being handled in the EU but also that
we have an arm of external affaires and handle those. Only then can the EU
defend itself.
Germany is having an election year this year and I do intend to vote for a
pro-EU and pro-solidarity party. Have a nice day.

Ditch the Computers for Elections!
March 4th, 2017
It's too bad what I'm about to say. But computers of today are not secure
enough for todays election (!!!). A white hat hacker in the Netherlands
agrees and has facts why. His story is at soylentnews.org. Computers these days are a
joke and I'll give you another example. I bought a computer in 1997. It was
the cheapest of its kind for $850, and they really skimped on the parts. That
same computer would be worth $1,240 today with inflation. But we can buy PC's
for $300 so they really got a lot cheaper and/or skimped on the parts (and
polluted rivers in China). We know they skimp on the parts because computers
have not become inherently safer. In fact they are faster but brain damaged.
So it's to no surprise that security software often slow computers down.
(Why is that?!) It's because security requires processing in order to make
smart decisions! I'll give you one example. The ISN of a TCP session in
OpenBSD uses the cryptographic routine called arc4random(). Do your homework
why this is important (see /usr/src/sys/netinet/tcp_subr.c - function
tcp_set_iss_tsm(), an RFC 1948 is quoted in the comments). So while computers
have gotten 4 times as cheap over 20 years, they haven't changed in design.
This is too bad, this must change! In fact I'd expect a computer to cost
more than $1,240 if it were anything more than crap!

My first SIP ALG program
February 26th, 2017
ALG is a VOIP term and means Application Layer Gateway. I have created in the
last week a SIP ALG program that I call rtptrack. It makes sure that outbound
(inbound untested) calls work on the t-online.de network. The router I use
is OpenBSD with the pf filtering system (which is supreme!).
The reason that t-online.de did not work with its existing setup was that they
don't utilize an "rtphelper" algorithm which helps RTP punch a hole into a
firewall. Sipgate.de and the VOIP company I work for do this and their setup
just works (tm). RTPtrack should make Telekom work too. Finally something
there works!
The download is here
for a limited time.

Networking Plans for future Computers in my Home
February 24th, 2017
I'm hoping to replace everything (everything!) in my house with 10 gbit
Ethernet equipment by/at the year 2020. For those equipments with many
ports I have planned to get a high-end NUC or so and a switch that does
VLAN'ing. My personal preferences for such a switch is 8+ ports and 22 watts
power consumption or so. I've seen some switches that do 40 watts and that's
too much for me. The cables will have to get upgraded too as they are cat5e
standard, and I believe 10gigE requires cat 6 or 7. At least the countup of
all of this is gonna be easy. These are my dreams for 2020 anyhow. There
is 3 years to go, and I know I'll get cravings to get new equipment in between
that. I hope I can stay disciplined enough.

ZeroPager.de domain about to expire
February 21st, 2017
I registered this one either last year or the year before as a test domain.
It served its function well. I'm letting it expire.

Jobless despite Certification
February 21st, 2017
Golem.de (a news portal I read) reports that
a 36 year old IT pro with system admin certifications and 10 years experience
can't find work. Hear, hear! I believe it as I'm unofficially looking as
well. Problem is that the golem article talks about 3000 such sysadmins also
can't find work. It makes you wonder what is going on here?
We get Linux certified and can't use our
skills? There is 50,000 job postings for IT jobs, why do 3000 people have to
be out of work? The industry has not adjusted to what people are being trained
on. Give us Linux jobs! Give us UN*X jobs! Also I would like to have the
government probe into workplaces that are just faking job postings. To gain
information for statistical purposes and advertising. If that is the case
it should be highly illegal.
