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!
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

The OpenBSDStore is in England. So ahead of Brexit I decided to buy three
posters from OpenBSD 5.8+ days. These will decorate my apartment soon.

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.

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.

I'm very happy of this. Here is the NSD log where the test zone was
pulled with the right key:

I'm very happy of this. Now I'm gonna try to take it easy for the rest of the
week. Happy February + March!

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

It's worked for five years. See here. I haven't changed much in the last little while to cause
any problems. So it's gmail who have updated some policy. I complained to
them, and hoping to get this straightened out.

It seems to me that the SPD is a puppet of a coalition partner. They keep
saying "may we?" and one really wonders what they are doing in government.
My statement to you: Make up your minds, because the outcome will determine
your votes next election. Meanwhile we have a real lack in fairness in this
social fabric in Germany. What are you gonna do, SPD?! And if it all fails
why are you still a coalition partner, in government?!

I spent monday to friday working on this, today I did a bit of regress work
to test records, I haven't found a bug since yesterday afternoon/evening.
The memory footprint of delphinusdnsd has been drastically reduced by order
of thousands. To give you some eye candy:
beta$ dddctl configtest -c
Records = 266094 , OK
beta$ ps auxwww|grep delphinusdnsd
_ddd 3694 0.0 0.0 1140 1164 ?? Ip 9:50PM 0:00.01 \
delphinusdnsd: unix controlling socket (delphinusdnsd)
root 88773 0.0 0.0 1108 1292 ?? Ssp 9:50PM 0:00.94 \
delphinusdnsd: master (delphinusdnsd)
_ddd 9236 0.0 1.4 467124 475856 ?? Sp 9:50PM 0:04.26 \
beta$ time dddctl configtest -c
Records = 266094 , OK
0m02.83s real 0m01.84s user 0m00.48s system
To explain this I have created a zone of A records from /usr/share/dict/words
which are 250K or so, on top of the 30K words I had in a zone. Before the
30K words too 13GB virtual memory, now 266093 records take up 467124K or 456M
virtual memory. I think it's super personally. Thanks to Otto at OpenBSD who
made me realise I need to change my database as the OS won't give me any more.
This is better anyhow. I have been thinking on how to apply my dns server
with this new db and I'm thinking of creating an updateable DNS server that
stores PAGEs from RAM of a computer. Because it is so fast I think it would
make wonderful project. Here in regards to its speed:
beta$ dddctl query -@192.168.177.2 antidisestablishmentarianism.words2

Before you grab a snapshot for this new database daemon give it a week for
bugs to be found and ironed out. But I checked it against current centroid.eu
zone and it seems to be OK. Anyhow remember the license says "AS IS", so it's
your fault if you use it now. This database will be in the 1.4 release which
will likely be in december.

The last two days I've been working on new database on delphinusdnsd. The
code needs to be adjusted and every file possibly will get touched. I may
be able to commit it on friday or next week, depending how long it takes.
The new database is not much unlike what I have written in the previous
article (fixed up for technicalities such as the _ENTRY's and TAILQ_HEAD's).
What I wrote previous article was without guidance of manual pages.
