Electricity for 2020

January 23rd, 2021

Good news, electricity is down. Bad news, daytime electricity is up and thus I have to pay extra money to the electric company.

Year	Night	Day	Total
2013	6941	1276	8217
2014	6906	1323	8229
2015	10151	1452	11603
2016	9643	1420	11063
2017	9788	1485	11273
2018	8546	1655	10201
2019	9064	1412	10476
2020	8578	1529	10107

Next year I'll draw a pretty graph, I may be in a different apartment too, which will have reduced heating costs (1 room less). I'll have to see if I find anything nice.

Here is a photo of me 1997

January 21st, 2021

An ex-girlfriend sent me this:

Thanks to Stacy for this! I was pretty slim back then. It was shortly before I entered the IT industry and got fat.

Three days compiling definitely paid off

January 14th, 2021

I have compiled iridium browser on my raspberry pi 4B. It worked! I'm in heaven! I wonder why these ports aren't found in openbsd-snapshot packages but the 3 days compile time could be a major factor why not.

Why does EU need a broadband satellite constellation?

January 14th, 2021

This I don't understand. Why does EU needs this? We're coming off as copycats and the fear of this for me is that it will be abused to decouple from the ONE Internet that we have now. This can't be happening. We're better off cooperating with American companies to give us broadband than doing our own and focus on some other things such as search engines and stuff. Or how about that 5G network? Is it even going to happen still?

Raspberry Pi 4B (8 GB) OpenBSD dmesg

On Christmas I got a Raspberry Pi, it's been running a few weeks now. I thought I'd share the dmesg:

Things I can part from (Schweinfurt schools)

January 12th, 2021

A woman of the Abendrealschule in Nuremberg is looking for computer netbooks or laptops for her students and asked an organisation that I'm a member of to provide old equipment. I live in Schweinfurt which is some ways away and we probably have a similar situation here, where there is students that only have a smartphone and no access to homeschooling equipment such as a netbook or a tablet computer. I'm offering my old equipment to a Schweinfurt school if it is needed.

I have 2 netbooks (one is 9 years old, the other is 6 years old) that I can part from, in case someone needs a used netbook for home schooling. The netbooks would need a bit of a cleaning (removal of stickers would require some cleaning of the exposed gooy surface with something such as "goo-off"). Both would need windows which I don't have any licenses for right now. As far as I know the built-in cameras all work and all other components do too. Both have 4 GB RAM minimally, one has a two core AMD 1000 MHz cpu and the other a 4 core Pentium cpu (1600 MHz?). They both have spinning harddrives.

If you can get cheap windows licenses I can even install windows on them for your child. Let me know if your child needs one of these.

Landing on polar Mars, the benefits and drawbacks

January 10th, 2021

In this article I talked about a mission to phobos instead of mars. But that has the ultimate drawback of too little gravity. Astronauts doing the trip will need to work out and replenish their bone marrow and muscles. So landing on Phobos is not a good idea, we need Mars' gravity.

However, I'm more a proponent of having humans land in a polar region of Mars the first time AND use the concept of Avatars being stationed around the equatorial region. This means command and control is in the "white" region and robots running around near the equator. But why? Because the cold may kill any bacterial life that we don't want returning to Earth. But it would also be damn cold for humans so we'd need nuclear generators most likely. I imagine the first human marstronauts will be inside their habitat controlling the robots 2000+ kilometers away, and then working on their own health with gym equipment. A trip out of these modules would be infrequent.

You'll thank me for this brainstorm when no martian virii make it to earth after the voyage home.

Happy New Year 2021

January 1st, 2021

I think it's gonna be a good year. New years propositions are that I want to get a job. I also have started 3 projects already last year. I'm giving freifunk a shot again. I hope it won't rob too much of my time. Also I have committed time to attempting to make my G5 run OpenBSD 64-bit. I committed 12 months for that so we'll see. And then there is my DNS server which may take a backseat to the other projects, meaning, that it may not be done everything by years end, but most likely next year some time. We'll see how it all unfolds. So 2021 is like the other years with recycled content. Old to the new :-).
