    Yes, I do have severe deuteranomaly. Diagnosed when I was 6 years old.

    I’ve read quite a lot about this, there are many cases where red/green blind people have exhibited above average night vision.

    I was also very good at spotting camouflage, since the patterns were designed to fool people with normal colour vision. The only time my colour blindness was a disadvantage was in a contest between regiments, I had to direct artillery fire as fast as possible and the targets were big red boxes in front of the treeline.

    Our lieutenant lost his shit when he realized that he had a colour blind forward observer. We still won the contest, my squad handled the measurements impeccably and I verified them on the map. There was discussion of transfering me to other duties after this, but when I asked “Sir, how many big red box targets are there are in real war?” they quickly dropped the issue.

    During my military service I also discovered that I had exceptional night vision. I never stumbled in the dark forest and I could even read maps when others couldn’t see shit. I didn’t pay much attention to this quirk, but my commanding officer realized this and put it to good use. The following overnight recon patrols on foot and skis felt endless.


  • My older daughter looked exactly the like her mother at the same age when she was 3-6 years old. When I compare their childhood photos it would be hard to tell which is which, if not for the hideous fashion of the 80’s being a a clear tell for mother.

    After the age of 7 my daughter quickly grew into her own look, but when she makes certain faces the resemblance is still striking.





  • I live in the Nordics and my house is prrimarily heated by a geothermal heat pump. The temperature here has been between -20C and -30C for the last week, the pump can easily keep the room temperatures at +19C until the outside temperatures drop under -25C, after that the electric resistor kicks in to provide assistance.

    The secondary heat source is the giant baking oven, which i heat every other day if gets this cold. The fully heated oven alone raises the room temperatures by 5-6C, which helps a lot to take the load of the heating pump and keeps the electric bill smaller.

    I have been planning to install air/air-water heat pumps to both floors, they would be a good backup during these cold spells and would also provide cooling during the summer. And if I install a smart control system, I can have the air units do extra heating/cooling automatically when the electricity is cheap.

    I just haven’t had the time to do the research where it would be best to install them and the prices rose steeply after Russia attacked Ukraine. So I’ll wait for a while before I’ll get those.


  • It’s getting harder every year.

    I remember well the constant fear of nuclear war in the 1980’s.

    I remember the wonder we felt when the Berlin Wall fell and Soviet Union collapsed. A hope of a tomorrow free of fear.

    I remember the dreadful recession of the early 1990’s and the steep economical rise that followed it.

    I remember the amazing advancements in technology and the standard of living in the late 1990’s. And at the same time, it felt like the world was coming to it’s senses.

    I was 21 in the year 2000. The world was full of promise, technological advancements were just pouring in, old mortal enemies were finding common ground and it seemed that we were slowly heading towards a Star Trek - like post scarcity utopia.

    This age of hope eneded by the finance crisis of 2007-2008. Russia tried the waters with the war in Georgia. The general atmosphere of the world turned towards gloom again. And the downward spiral just seems to keeps going and going…

    Yet I continue the work I started when I chose teaching as my profession in those golden years of hope. The kids are very different today, any class from 20 years ago would be a piece of cake compared with the problems they have now. But if a change for the better is to come, it will come from the kids. My generation is hopelessly lost in consumer greed and watching mindless “reality” shows that they somehow feel more important than real life.

    I alone cannot be the change we need, but I CAN educate a few hundred kids and with good luck, maybe a dozen or few of them will have a some effect for a better future.


  • I have a a working box camera from 1930’s. Or it would work, if I could still find film for it at a semi-decent price.

    My Sansui 1000X - receiver amp is in daily use and was made in 1971, it’s in near mint condition in every way. I did a complete internal cleanup and replaced a few electrolytic capasitors just to be sure to avoid any problems in the future. I believe the unit may well outlive me. I love the silverface-teak cabinet aesthetics. It’s paired with a Lenco - L75 turntable from the early 70’s and AR-7x speakers from the same decade, together they sound pretty much perfect to my ears.

    And I also have my great-aunt’s windable table clock. It’s ~100-120 years old, but still works if only I remembered to wind it every other day.

    I remember reading some scientic article that examined what would happen if we eradicated the mosquitos entirely.

    Surprisingly, they came to the conclusion that they’d just be gone and we would be a lot happier without the nuisance and the diseases they spread.

    No other species is dependent on mosquitos as a food source, they could easily find enough to eat with them gone. Mosquitos apparently serve no known vital purpose in their ecosystems, although it was mentioned that males of some species have some little value as secondary pollinators.







  • I bought a 2 gen iPod Nano 8GB in 2007 and I have used this amazing device almost daily ever since. The original battery somehow still managed to hold a 5-6h charge last spring, but after the summer it can only do 2-3h of continous playback. I already ordered a replacement battery.

    The jogwheel can be easily operated through your pocket fabric which makes it far superior to touchscreens.

    I intend to keep using it as long as I can and I’ve already picked up a few spare ones in case it breaks beyond repair.


  • More often than you’d think.

    When I lived alone while studying, I usually kept only a tiny kitchen worklight on. My friends were always baffled by this when they came to visit.

    Once my co-worker asked to borrow my favourite sunglasses. When she put them on, she was still for a moment and then went “MY DEAR GOD, HOW CAN YOU SEE ANYTHING WITH THESE ON?”

    The only sunglasses that make sunny days outside enjoyable for me. And yes, they are very dark.
