Let’s see how high Meshtastic can fly.

OK, the big experiment has begun. A ham radio group has funded the scanning of 4,000 manuals from the Great Manuals Plus Haul. Now, the experiment is - will people kick on a special link in the blog entry to help fund the other 20 PALLETS of manuals?

I built myself one of these today for some /p action when it gets warmer again. Nice and simple λ 1/4 antenna. The plan is to use it with an ADX-S qrp TRX which yet has to be delivered from china.

The trolley problem: your imagination versus the even sadder reality. (Just got this from a friend who also collects trolley problem variants.)

Above: how you imagine the trolley problem: an image with you at the switch

Below: How it’s actually going to be: you on the rails with many people, and the person with the switch being paid by the person on the other track

Katherine Johnson passed away in 2020, at the age of 101. Editorial cartoonist Steve Breen’s lovely tribute perfectly captured Johnson’s contributions to the US space program.

Steve Breen's editorial cartoon for the San Diego Union-Tribune shows Johnson working at a blackboard. The equations she writes out in chalk become a stairway that an astronaut in a spacesuit follows to the Moon.

Amateur radio is the hobby of "Not sure if that antenna will work? Just try it. You might be surprised!"

I've seen people load up all kinds of crazy things for antennas, including the chain link backstop on a baseball field, aluminum patio chairs, and those wire cages you put around tomato plants. I saw a guy load up an incandescent light bulb on WSPR and was heard halfway across the country.

Stop agonizing about it, and just try it!

So, der Umzug bedeutet nun also tatsächlich eine Konstante im Leben weniger als geplant:
Mein angeblich so flexibler und familienfreundlicher Arbeitgeber hat „kein gutes Bauchgefühl“ wenn ich weiter weg ins HomeOffice wechsle und wird mich dann nicht weiter beschäftigen.
Wenn ihr also positive Erfahrungen gemacht habt mit einem Arbeitgeber der Entwickler in Teilzeit (60-70%) im HomeOffice beschäftigt dann freue ich mich über eine Empfehlung. Evtl werden wir ja Kollegen?

I did it! I made an epicycle clock!

I think Mastodon people should use the "like" button more.

People are told not to like because liking doesn't broadcast posts like boosting does, and the site needs boosts. And replies are preferred because they're deeper engagement or something.

But, on some level, we want people to keep using Mastodon. If someone posts something and followers like it, they know stuff is getting seen here and they'll want to keep using the site. I just don't see what's gained by holding back on the likes

RT @NigelWitham

Mowing became fashionable during the Industrial Revolution when it was how the wealthy showed off they didn't need to grow their own food.

250 years on and manicured lawns are so embedded in our culture that despite the adverse impacts many can't envision any alternatives.
