  • The puzzling part is fun, because you are constantly learning new ways to use your body. See how to balance, how to move around, etc. I have found that dancing gives a similar learning challenge. Especially the more free-form dances like salsa and bachata. It’s fun learning new moves every week during the lesson, and then try to see if you can put them to practise during a party.

    And don’t worry about beeing to stiff. If you can balance around boulders, you can get your body to move around for dancing too. Just takes some practise. I currently do both, and feel like I lack dexterity more for the climbing than for the dancing.

    And unlike most of the hand-friendly options mentioned already, you do have to use your hands and arms a lot. Just not in a way that puts any stress on them.



  • Point 1 has to be chosen when the cat is young. Forcing an outside cat to suddenly only be inside often doesn’t work.

    I adopted a 7-year-old cat from the shelter, and after a week of having to be inside all the time, he got more and more frustrated. After a week and a half, he escaped during the night. In the morning, while I was panicking, he came strolling in as if nothing was wrong.

    Since he apparently comes back, I allowed him outside from then on. Since that moment, his behaviour inside has improved a lot. No more random play attacks on my ankles and hands, and generally much calmer.

    He has also come back home with mice several times. He always eats them. So I think he is very used to living outside. Maybe been a stray, or a farm cat.

    Forcing him to be inside would feel cruel.






  • You can look up what the acronym AESA means without unstanding it.

    Take two speakers that are next to each other. If they emit a tone of the same frequency, the sound will “add up” and be louder in some directions, and cancel out to some degree in others.

    A phased array radar uses the same concept, but now on electro magnectic waves, instead of sound waves. And with much more than just 2 emitters. By carefully choosing the phase of the signal in each emitter, itnis possible to both choose a single direction that receives the strongest signal, and to tighten the spread around that direction (creating a pencil beam). This is what the dish is for in standard radars.

    If these phases can be fully controlled electronically, you can steer where you are looking, and swap between wide and narrow search beams in an instant. However, that is not a trivial thing to produce. So cheaper phased array radars use mechanical systems, or partial electronic steering (example: only horizontal steering).










  • There is a subtle, but important, difference between letting people know your product exists or improved, and brainwashing people into buying your product.

    Is a grocery saleman at the local saturday market allowed to shout about the sale he is doing on strawberries? Because that is also marketing.

    I fully agree that the average advertisement you see on youtube is pure cancer. But what about an advertisement for an emergency fund for a disaster?

    What about a sponsored video of a game?

    Where do you draw the line?
