Energiewende in Danger

June 10th, 2016

Germany's transition to green energy is in danger from shifting policies in government. One argument is that they think that we're overproducing electricity, so I have an idea. We could create hydrogen with excess electricity and sell it to Iceland via ships. The ships sail back via Norway (empty) and fill up with natural gas and then return to Germany. It's a sort of triangle trade (without slaves), but with substances that require high pressure. Also we could use hydrogen locally until there is no more need to export it to Iceland. Think about it! Makes perfect sense.

Here is some links:

Why I prefer BIND over unbound currently

June 10th, 2016

I have set up a BIND nameserver on my gateway at home. I also have set up BIND nameservers on io.solarscale.de and omega.virgostar.net. The three talk to each other with the use of secret keys (TSIG queries). AFAIK unbound cannot do this as I googled once and saw a question by Jan-Piet Mens (an author of DNS books) ask about that feature on unbound and the reply was negative. So it will have to be BIND, even though they are about to change their license to a Mozilla license as compared to a BSD license. That announcement was made at RIPE 72 in Copenhagen. OpenBSD which was represented by Peter Hessler said they were against that, and it brings back memories of the ipf/pf spat. However OpenBSD decided to go with unbound/nsd a few years back already so there is likely no change.

Brexit, I'd like UK to stay

June 4th, 2016

There is really not much to talk about here other than the worry that we're all gonna lose out if the UK splits. What would happen to the UK if they decided to take their own path? What would happen to us?

Realistically seen the UK fits to Europe like jeans to a human. What would they do without the benefit of having a large continental body right next to them? I guess there is Canada and Australia and New Zealand. But those are far away. Ie. if the commonwealth gets put into a political union more than it already is... would that work? And would the commonwealth be willing to enter a loose-knit union strewn all over the globe?

I think for those people in the UK that want to see change, they should strive for that change within the EU. It might be beneficial for all of us. Won't you stay, (a little bit longer)?

Gotthard Base Tunnel

June 4th, 2016

This link(german) talks a little about the Gotthard Base Tunnel. I guess Switzerland is not in the EU but they have positioned themselves to transit goods via this tunnel between Italy and the rest of the EU. This is a great deal for them and I'm a little jealous they can take all the glory. Surely there must be benefits for us, ie. cleaner air from the Alps because Lorry drivers should take a train now. That remains to be smelled and tasted. I don't think I'll notice a diff. However a lot of Europeans quality of life may get better minutely due to this tunnel. Another great tunnel would be the Finland-Estonia tunnel if it ever makes the drawing board and political acceptance.

Moved delphinusdnsd

May 26th, 2016

I have moved my in-production delphinusdnsd back as a hidden master. It will only do AXFR's now to the slaves. What's replacing the authoritative end on omega.virgostar.net is a BIND nameserver, which will also do recursion eventually (with TSIG key).

In other DNS news my domain name swshell.de is still on the denic nameservers and I don't know why it's not removed, the domain is expired.

Still other DNS news is that delphinusdnsd has a problem with the database. It goes into an infinite loop under some condition while querying the database. I did a tcpdump at the same time and it doesn't appear to be outside traffic causing this. I'll be stripping the berkeley db eventually I suspect and replacing it with something homegrown.

Instead of Toronto, Ireland?

May 20th, 2016

I'm weighing the option of going with an Irish AWS instance instead of a Toronto Digital Ocean instance. Difference is that I'll be able to run OpenBSD on AWS. Tomorrow americas.centroid.eu will expire. Days later the domain name swshell.de that is hosted on there will expire too. Then I'll do clean-up of the authoritative domain names (removing glue records etc). I'm still undecided on the Ireland thing, we'll see.

5 days left for americas.centroid.eu

May 16th, 2016

Americas.centroid.eu I'M letting expire. It's my vps jail in panama. It expires in 5 days. What I'm doing is I'm renting another vps in toronto from digital ocean. It will be a DNS recursive server at first. Along with io.solarscale.de I'm going to make them recursive with TSIG security so that my home network uses them. Since I regularily download from a server at 151 Front in Toronto I know that I get about 1.1 MBit/s on that route. That's enough for a DNS server, which uses a lot less. Only problem is that there may be passive dns spies along the route. Hmm oh well, more money to the north americans I guess.

Ordered books

May 15th, 2016

I have ordered the following books:

Construction of Attack-Resilient and Efficient Overlay Topologies for Large-Scale P2P-based IPTV Infrastructures - Mathias Fischer
P2P Networking and Applications - John Buford et al.
P2P-basierte Gruppenkommunication in drahtlosen Ad-hoc-Netzen - Peter Baumung

If you'd guess what would I do with these and other purchases of books? Perhaps something with SIP and P2P perhaps?
