I got another APC-650 BackUPS. This is the second of this model, I'm quite
happy with it. This is connected to my monitor, workstation and voip phone.
According to the OpenBSD upd driver it gives me 22 minutes to shutdown the
system and do a phone call that I'M unavailable and do other emergency
procedures. The UPS in the hallway on the DSL modem has about the same
charge.
hw.sensors.upd0.percent0=100.00% (RemainingCapacity), OK
hw.sensors.upd0.percent1=100.00% (FullChargeCapacity), OK
hw.sensors.upd0.timedelta0=1357.000000 secs (RunTimeToEmpty), OK
That's the output from a sysctl hw. I still have to put on the AP which
switches the voip phone or it's all for naught so I'm hoping to be getting
about >20 minutes still.

Equinox in 4 days
March 16th, 2019
Equinox is upon us again
in four days. From then on the nights should be shorter than the days. It
also marks the official start of spring in the northern hemisphere and start
of autumn in the southern hemisphere.

The difference between wrong and accurate timing
March 12th, 2019
In Germany everyone is a taxpayer. We have a general sales tax, so even if
you buy a snickers bar you're a tax payer. Just it's hidden from you, but
it doesn't matter how they apply it, what my article is about is time.
DCF77 is a signal that is sent out by a public institution paid for by tax
payers. It is an important piece of infrastructure for Germany and I remember
clearly from grade five in 1986 when people had the first digital watches that
made use of this signal. In fact a lot of things in Germany depend on it.
When I cycled from Frankfurt to an undisclosed location 90 km up river along
the Main river I passed the transmitting towers of Mainflingen which is the
location where DCF77 is sent from, there is several atomic clocks that make
this signal accurate at the time of send. I approached a company making
radio clocks for computers that use the DCF77 signal, and low and behold they
don't sell to individuals, only corporate firms.
So to sum up. They, are a company that
leans on a signal, paid for by tax payers (ie. everyone) to make income yet
they don't sell back to the tax payer. Funny that. And all their contacts
of resellers sell only to corporate customers as well. They also lean on
Galileo signals paid for by europeans, and GPS paid for by americans for
other products, but I'm only concerned with the DCF77 products right now.
It's rather ridiculous that I have to jump through hoops to get accurate time,
ie. SDR or bettering NTP, when all it could have been is a simple order through
a friggen web interface.

CryptoBook USB
March 12th, 2019
So, four years ago I made cryptobook, which is a USB stick based encryption and
decryption tool. It works on basis of one time pads, which when the algorithm
creating the random numbers is secure, are secure.
cryptobook.tar.7z
For the cryptobook you'll require a recent vmware fusion for it to work. The
OS on the cryptobook is OpenBSD 5.8 so it is 4 years old. Have a lot of fun!
Back four years ago I made a manual as well explaining how cryptobook is made.
But it's in german. Anyhow here it is in
pdf format. Please be aware that you can just encrypt little things with
cryptobook although it uses a 4GB pad max. The pad gets shared among your
family or co-workers and then you can encrype AES keys for example and
securely transfer those per USB stick. USB sticks cost 5 EUR in 2015 for a
8GB stick. Today you can get a 16-32 GB stick for that, but I'd stick with
8 GB.

I am against upload filters (article 13)
March 12th, 2019
There is a big stir in europe about article 13. While I don't understand the
specifics, it leads one to think that the EU wants us to be consumers and not
upload to platforms such as youtube at all. This can't be! What we need is
a search engine that is customizable so that everyone can find what they want
to see. Put restraints on just what a community wants is not really a good
idea, because people inside communities want different things. The german
wikipedia is protesting article 13 by shutting down on March 21st. I think
that's a drastic wrong. Don't fight a wrong with another wrong!
So what
I have done is I copied 416,000 articles from wikipedia and put them on a
private vps. With 50 GB SSD space that's all the compressed 5 GB dump plus
the import could handle. So roughly spoken the german wikipedia needs around
128-150 GB of space, that's a good to know. I'm also glad I know the process
of copying wikipedia now, and the ImportDump.php program in wikimedia has a
memory leak unfortunately I had to restart it with a new offset half way
through.

Crimped three patch cables
March 6th, 2019
A fourth patch cable I threw out for being bad. But I basically checked what
these patch cables go for (cat 5e, RJ45) and the are between 1 and 8 EUR. So
I've bought myself lunch with this.
There is order now in my cabinet. One thing I'd need is a labeller, but that
will be in due time. I can't justify it for 3 ports.

I have a job interview tomorrow
March 6th, 2019
Finally an opportunity to make some money again. I have been lightly
searching since last summer. In the meanwhile I did several projects
the powerpc64 project, getting a closer look at windows server and some
time invested in delphinusdnsds (which seems to get better with time).
I didn't secure a grant this year and I'm not trying again (that was
prototype fund). Also the electric car didn't work out in 2018. Maybe
in 2019, if I get paying work, I'll get a colocation at an ISP, other
than that I'm considering rebuilding mail at vultr.com VPS's. That work
should be done by November. So that's where I am job and projects wise.

New delphinusdnsd in production
February 22nd, 2019
I have put on a snapshot of last night on into production on
omega.virgostar.net. I'm hoping it's alright I tested it to
the best of my ability. Fixes are: an ENT reply with dnssec
option on (see. ent.dtschland.eu), and it has a new database
that I put together by February 16th. Since then I just fixed
a few bugs and hope it's bugfree by now.
;; ANSWER SECTION:
version.bind. 3600 CH TXT "delphinusdnsd-20190222"
That is a version reply of omega's delphinusdnsd indicating it is
from today. The query string was: @omega.virgostar.net version.bind ch txt
