Purchased last batch of books for year

October 28th, 2017

Last year I purchased 15 books in total. I matched that this year. Here is the last batch of books that I bought for 2017.

  • Artificial Intelligence: A Modern Approach, Global Edition - Russell, Stuart,Norvig, Peter
  • Astrometry for Astrophysics: Methods, Models, and Applications - van Altena, William F.
  • Fundamentals of Astrometry - Kovalevsky, Jean
I decided to buy two books on astrometry because yesterday I was sifting through ESA's Gaia mission page and downloaded data regarding the parallax of of stars that this mission constructed. It's unrelated to the books but if you were curious check here. I plan to make a small program to help me determine the closest stars in any region in the sky. Anyhow I noticed the data was cross referenced to the Hipparcos mission which ran earlier and did parallax astrometry as well. I found the 13th most distant star from earth in the constellation virgo was called Ross 128 aka HIP 57548. In the distances paper that I got the data from it is the closest star. Why I don't know but it is, I sorted the data and checked. Perhaps because the other 12 closer stars are too close? Or are well known? Anyhow to get to the bottom of some of my questions I bought these books. I'll have to have a lot of reading to do. Perhaps I can couple astrometry with artificial intelligence one day. LOL.


Delphinusdnsd: What's ahead in the next two months

October 27th, 2017

The year is coming to an end in 2 months, and I'm going to tell what there is still to do until the 1.2.0 release. I'm working on patches to make delphinusdnsd work more around the imsg functions found in OpenBSD. I'm hoping for one more week of vacation between christmas and new years and then I'm going to likely roll the 1.2.0 release. Right now we're a go for a January 1, 2018 release. Time will tell if that is manageable. Beyond the two months I don't want to speculate too much. But I'm interested in putting CAA support in for the 1.3.0 release. Also I need to do key-rollover in DNSSEC as my own zones need new keys (RSA 1024 bit strength currently).


Purchased Fundraiser Tees

October 24th, 2017

I have purchased two fundraiser t-shirts designed by a friend of mine's daughter that will ultimately rebuild a Nunavut school in Canada. Read the hyperlink to gain more information. Thanks goes to Jackie who helped finding my mails in the stores Junk mail folder. The t-shirts I have asked the store to send to my niece and nephew, also in Canada.


Finished upgrades to 6.2

October 17th, 2017

I had finished my upgrades to OpenBSD 6.2 on saturday, but i wanted to do a network wide backup as well. That was done last night. AFAICR my network doesn't have any more 6.1 or 6.0 machines.


Krack Attack, WPA2 broken?

October 16th, 2017

The rumour of the day is that WPA2 is broken. here is a writeup by arsetechnica. At home I'm mostly OK I think as I wrap my layer 3 in IPSEC as well, so if WPA2 is broken there is another layer to crack. Hopefully there will be patches though.


A 49 qubit Google Quantum Computer by end of year?

October 14th, 2017

I came across this. Google wants to achieve Quantum supremacy. I find this scary for an advertising company to wield so much power. As you know, I'M somewhat anti-advertising and don't have any banners on this blog or website. Although I still have some friends that are involved in the advertising industry. Where will it all lead us?


Donation time again

October 9th, 2017

I have donated 35 EUR to OpenBSD. Cheers!


OpenBSD 6.2 released today

October 9th, 2017

Happy Canadian Thanksgiving! Just in time for turkey dinner OpenBSD released its version 6.2. Enjoy! And don't forget to donate!


Temporarily going back to AC

October 9th, 2017

The router that I put on DC/Solar is going to be turned off by me tomorrow and put back on AC until possibly friday morning. When I bought the battery it was said to be charged but it may not have been 100% charged. I now learned that we won't have sunny weather in the forecast until friday so I'm doing this. Since I don't have a battery charger this is the best way to conserve power. Friday is supposed to be 10 hours sunshine, I'm really looking forward to it.


Switched on the Solar Router

October 7th, 2017

My dad and I finished the cabling and battery work yesterday and I switched on the Freifunk router on the DC-DC adapter at 9PM yesterday. I figured out the battery can last 7 days or so without the panel charging it. We'll see how that goes. Here is an image of the setup now.

You may recall an earlier article where the entire panel was shown from the backside. Just in case you don't I'll provide it here.

The forecast around here is not that rosy so I'm hoping for sunlight between 2PM and evening at any chance to charge the battery. We'll see. So far this project has cost around 550 EUR, but I got all the CE certified devices and there was very little custom cabling being done. What I don't have is an AC-DC battery charger, I hope I can do without with this 100 Watt panel. But who knows what the future holds. I'm very happy how this all turned out.
