and breathing flux is a far larger concern than leaded solder. Physically getting them somewhere (eating while soldering, not washing hands, etc) is still a problem.

This. Just to expand on what you said a bit (since this is aimed at soldering newbies)...

The fumes from leaded solder don't themselves contain lead. The iron isn't hot enough to vaporize the metal itself. The fumes are from the flux, and breathing those can be problematic.

The immediate health risk in using leaded solder is all about touch and ingestion. Handling the solder gets lead on your fingers. That in and of itself is not a health risk unless you have a wound. But then if you touch food or mucous membranes (pick your nose, put your finger in your mouth, rub your eyes, etc.), you can get lead in your system. Not much, but once there, it doesn't leave, so accumulates over time.

You can mitigate those risks by wearing gloves, washing your hands immediately after you're done, and being rigorous about not eating or drinking at the bench and not touching other parts of your body. Non of that helps with the environmental problems of using lead, of course.

Both lead and lead free solder use the same chemical flux in their core. So you have the same problem with leaded flux cored solder. With the additional problem of lead.

I've never seen a coffee mug, or glass drinking vessel wear out. They always end up broken first.

using 'roof solar is expensive, therefor solar is expensive" is borderline disingenuous. It's well established that roof solar is freqently not cost effective.

Which has little relation to installing 100 acres worth. and, its likely the ROI will get even higher as we build more solar fields, and more HV transmission lines.

they do take it at a single place and time though! 12:00.00, then 12:00.033, then 12:00.066, then 12:00.1....

I'll go out on a limb and say that's their argument if it goes to court. maybe it's only 5fps instead of 30. It's still the kind of BS the courts need to stop allowing.

for games its more often .net BinarySerializer.

A lot of unity games does it, especially the 'legacy' serializer

I've not done unity3d dev- but yea, all I've seen from it are games using XML, or BinarySerializer. sometimes its compressed.

A lot of older stuff just dumped structs in general

like apache parquet?

they said they didn't change the behavior for range requests. So, it'll still be the basic no compression. (eg, server side decompression)

afaik, ZFS will read an entire Record at a time- and that's the same granularity as its compression.

Everybody is focused on the tubes... What about the diffuser with pyramid shaped lenses? the highly directional light projects a beam (flourescent lights are known for awfully harsh shadows) through the thin, lightweight 24x24" or 24x48" lens(diffuser). as the light is projected down a minimum of 8 feet the tiny deflection from sound hitting the diffuser is amplified. Then, at an interface of light and shadow on the floor, the moving projection becomes a brightness signal that has audio encoded in it. they could use a lens and a photodiode. Didn't exactly have 5000fps cameras falling off trees 40 years ago.
