TLS for centroid.eu blog, when?

September 14th, 2016

I'm going to restructure the website and the blog probably after the OpenBSD 6.1 release. Apparently there is a program in that release that manages certificates from "let's encrypt". Since I'd want my whole website encrypted I'd have to use let's encrypt several times to fully encrypt my website which contains the domains virgostar.net, solarscale.de and centroid.eu. So if you think the obfuscation is good enough, don't let it fool you, it was made for a defense against bots (that don't know javascript) not to thwart spying eyes. I'd run the same blog software only inside TLS with let's encrypt. Props have to be given to Edward Snowden for his whistleblowing which caused organizations like "let's encrypt" to form in the first place. Encryption should be free!


One more panic chronicle entry

September 9th, 2016

I woke up today to a panic'ed router/gateway. What a way to start the day. backtrace here. Why am I not sending these to OpenBSD anymore? dunno. I remembered there was a reason once.


I had photographed Vega and Constellation Hercules

August 30th, 2016

This picture is from June 27th, 2010 so a little over 6 years ago. My dad and I were on the Peterstirn which is outside of Schweinfurt (the city that I live in). This article is in relevance to the last article and I wanted to show it again. I have made a cut-off from the original RAW Photo and I want to show you this. Feel free to open the photo in another tab to make it it's original size.

As you can see this area of the sky (at least in june) is visible. You just gotta know what to look for. If you can find Vega you can find constellation Lyra and from there the area that's circled which is part of Hercules. Inside the circle somewhere lies the star system that emanates an 11 GHz signal.

Update. I have added the label to a star I think is called Ras Alhague in the constellation Ophiuchus. Constellation Hercules goes further up from here but I don't have that in my photo.


The whereabouts of HD164595 in Hercules

August 30th, 2016

Slashdot made me aware of this story of a SETI signal that was observed, last year by a russian SETI installation.

I have plotted the rough area of HD164595 it's somewhere in the circle but what's important is the relative near-ness to the star Vega. It's in the constellation Hercules, and should be visible this summer with Telescopes. As far as aliens reacting to broadcasts from Earth they have just now recieved signals from 1920's because they are 95 light years away. However they might have been reacting to carbon in our atmosphere due to the start of the industrial revolution in the 1800's. Meaning the aliens have telescopes. It is hypothesized that they are a Kardashev scale I civilization if they are directing this towards only us, so they are more advanced than us.

May they keep the signal going with the strength of Hercules :-).


OpenBSD 6.0 Poster arrived

August 24th, 2016

I have hung up this poster where the 5.8 poster was. I notice it's somewhat crooked.

This puts my office into a darker hue. Which suits the onclosing winter season.


Ordered a Banana Pi R1 Routerboard + Case

August 22nd, 2016

I ordered this at roughly 100 EUR. The powersupply says it can deliver 2 Amps at 5V meaning 10 watts. If this is true and if OpenBSD runs on this I'm going to replace my i386 firewall that currently sucks 20 watts. I'll just have to try it out I guess. If I don't get OpenBSD on it there is probably a chance to run another UBO on it, or I could donate it to a developer. Will have to see.


Delphinusdnsd: Next week selfathon

August 22nd, 2016

I'm going on holiday for a week next week. I'm going to solely program on delphinusdnsd to get it in a state where I would be in a better position with it. On the menu is dd-convert.c to replace the ruby script. If I get time beyond that I'll work on making the dns keys rolloverable. Oh well good luck to myself.


Eleven Reasons to be excited about the future of Technology

August 19th, 2016

Slashdot wrote this. I'd like to add my own opinion whether I'm excited or not.

  1. Self-Driving Cars - worry me. A car is a weapon when misused.
  2. Clean Energy - we're not there yet and will we ever be?
  3. Virtual and Augmented Reality - used to excite me, but the devices are locked down to only work on proprietary systems. Who wants to go pokemon go hunting anyhow? Do we really need this in our lives?
  4. Drones and flying cars - hmm. cool. When I still lived in .ca this would be cool to make the "suburbs" 700 km northwards, here in .eu it doesn't really matter since everything is settled land.
  5. Artificial Intelligence - would be cool to have it answer my VOIP phone and weed out voip spammers. Could it weed out my e-mail spam?
  6. Pocket Supercomputers for Everyone - with choice of OS or programability?
  7. Cryptocurrencies and Blockchains - I don't even know what that is
  8. High-Quality Online Education - This is cool, however "da man" knows what you're currently being taught. Playing hooky?
  9. Better food through science - if it's tastier why not?
  10. Computerized Medicine - if I swallow a "smart" pill that releases its dosis at the right moment that could be beneficial. Similarily nano-robots could be inserted into the blood stream, if that's possible I want virtual reality to watch it go..
  11. A new space age - yeah yeah.. where are our torus space stations that were in stanley kubrick's 2001 A Space Odyssey? Missions to Jupiter? HAL 9000's? oh we actually got the HAL, it's called Watson
Think I'm a bit pessimistic today.


The Panic Chronicles

August 19th, 2016

I have started the "panic chronicles" a blog-like bug report on what can go wrong on OpenBSD. As I find bugs I'm sure to write them here.



My all-prime angled triangles

August 16th, 2016

I thought about this tonight and figured it out with the help of a small shell script. There is only 6 possible of this kind of triangle in the universe. I have listed them in a picture below.

They look like shards. And are different sizes, the ratio of sizes I didn't mind because I got the images from an online triangle calculator.
