Burning random manufactured stuff makes dioxins. It would be astonishing if there weren't dioxins in the soil before the accident and some more after it. This being the rural United States, burn barrels for household waste were a thing

It looks like the author is changing the light color and intensity throughout the day to approximate the color of sunlight. But he has a bunch of LEDs in different spatial locations… You could make the LEDs be different colors based on loca

Also, maintaining vacuum is probably easier in larger units since the volume is increasing faster than the surface area. More gas intrudes, but there is much more space for it to intrude. The wildcard is what has to change for the thickne

I just checked out a couple videos of hydrogen filled party balloons being lit. I think it’s safe to say it could be a pants wetting experience and likely ignite paper party decorations.

That's a lot of text obscuring "we might decide to kill you, and that will be just fine". I might have even moved that up above "we might fine you".

One phase of the lifecycle only happens in humans and dogs. Once no one (or their dog) has it, then the cycle is done. The out-of-human part is three phases of larva which take a few weeks, although I didn’t see how long the phase 3 larva c

If when you coil a long cable or hose you find yourself fighting a twist as you coil… then you should learn to coil in an alternating overhand/underhand style. Google a video. Basically when grabbing the next hunk of cable you alternat

It speaks poorly of an industry if there is a market for a toll gate to mush things into a common format. It appears the plan with pricing doesn't include the weather data, just the transformation. You still need keys to the ultimate s

Neither are the upper case letters or the underscore. Those are all composed with multiple keys. Easy enough to carve one out for the new separator.

This has remained unsettled for 60 years. Perhaps we need a new choice? How about Unicode "Thin Space" 0x2009 for a legal identifier character? (HN isn't letting me put the Thin Space in there.) How about Unicode "Middle

I haven’t looked at my tail lights, but in the US most cars have used the same bulb for hazard and brake. So the bulbs are already fully illuminated. Cars meant for the rest of the world have separate yellow lights in back and you could fl

e.g. driving a couple of miles at moderate speed until there's a safer pull-off opportunity I'm fairly certain this isn't a legal option in the United States. That would be unattended self driving. It's probably a bett

Actually… kind of common in parts of Kentucky. My son in law arranged for us to buy a gallon to subdivide for gifts. Guy showed up with moonshine in the trunk. This is rural Kentucky, so you can't just have a transaction, you have to t

To elaborate, rsync chunks in fixed sizes, so inserting or deleting a few bytes makes all different chunks from that point onward. If instead you chunk based off of local content (conceptually like chunking text into sentences at periods, b

I've implemented PAT on a service. A server would only want to require PAT when it wants to see if it is dealing with a human. In the context of, say a blog, you would require PAT when someone wants to make an anonymous comment or crea

Just because it gets distorted, not that it changes the message. The solar panels installed on the White House during the Carter years were a solar hot water heater, not a photovoltaic system. Here is part of his speech from the dedication

With an atmospheric density 1/150th that of Earth, the engineering of a leaf blower might be tricky. Clearly the atmosphere can move dust, but you might hit speed of sound problems in your turbine. Someone should spend a couple years

The common RV battery for cold weather is a LiFePO4 battery. These can be used down to -20°C (-4°F), but you must not charge them below freezing, it will destroy the electrodes. The batteries integrate a heater which absorbs charging energy

Acrylic and water have virtually the same index of refraction, so if the crack forms on the wet side of the wall and wicks in water you will not detect it visually. It forms the basis of some magic tricks involving walking on or supporting

The maximum efficiency of a steam turbine is just shy of 50%, by the time you have integrated the whole plant, 23-35% is typical. (so says wikipedia) The sort of solar panels one would use in a large installation are around 23% efficient. S
