Ooops.
Caution at below 27 °C (80 F)? Always? Why is there no “OK” zone?

Okay, let’s roll with that Why should there be… holes? in the middle of the wing all over the place? And why should Russia(?) not be able to fix that?
So what are we actually looking at? What does the tape actually do?
Eheran@lemmy.worldto Not The Onion@lemmy.world•Elon Musk's robotaxi will have a human driver for 'safety' reasonsEnglish79·18 days agoHyperloop was a raging success - it stopped funding of railway. I believe he even admitted that this was behind it to begin with.

Eheran@lemmy.worldto homeassistant@lemmy.world•Long-term feedback: SONOFF SNZB-02D humidity/temperature sensorEnglish6·19 days agoHow did you check the accuracy of the humidity sensor? All of the cheap ones tend to drift/fail fairly quickly, especially if there is condensation (high humidity). This includes initially highly accurate sensors like BME280.
Huh, not some crypto bullshit or what not scam? That is my absolute default expectation today of anyone messaging me.

Why should anyone switch away from VGA, works just fine? No need for USB, PS2 etc. work just fine.
Eheran@lemmy.worldto Selfhosted@lemmy.world•Plex now want to SELL your personal dataEnglish3·1 month agoWow. But now I had to look it up, the German “ARD Mediathek” has over 200’000 files, a playtime of 100’000 hours.

Eheran@lemmy.worldto Technology@lemmy.world•Penn Engineers Discover a New Class of Materials That Passively Harvest Water from AirEnglish13·1 month agoPeople were able to (and at some places did) cut down every tree WELL before they had power tools and even saws. Just with axes. The comparison is laughable.
No, massive air moving structures can not be cheap. Neither building nor operating them.
Eheran@lemmy.worldto Technology@lemmy.world•Penn Engineers Discover a New Class of Materials That Passively Harvest Water from AirEnglish12·1 month agoNobody will remove water from ambient air in relevant amounts. Roughly 0.5 % of air is water vapor, a total of something like 10’000 km³ liquid water. This is replaced (residence time) about once every 10 days, so roughly 1’000 km³ daily.
Say we extract 10 km³ (10’000’000 m³) daily, enough for roughly 10 million people (including all industry, zero recycling of the water etc.). By that time you deal with 1 % of earths atmosphere every day. May I remind everyone how absurdly costly in any conceivable way that would be? You would rather lay a few pipes and purify sea water at a tiny(!) fraction of the cost.

They lose their coercivity far sooner. The higher the magnetization, the more sensitive it is. So N52 is more temperature sensitive than N45 (but both start to suffer around 80 °C). You also get alloys that are more tolerant and get specifications like 44H that can be used up to 120 °C or 35SH up to 150 °C.
Eheran@lemmy.worldto Technology@lemmy.world•The most powerful laser in the US recently produced 2 quadrillion watts of powerEnglish31·2 months agoYou multiply seconds with seconds per hour and somehow get “per hour” as the final result? But even ignoring that error, what is W/h supposed to be? Rate of change of power?
Also, it is a small k for kilo and you don’t write it as 4.31018[unit]. Just 4.310^18 [unit]. Or 4.3E18 [unit].
Graduation is the peak of life…? In what metric is that supposed to be the case? Number of graduations per year?
