I mean, it's on their own lawn, I think, so I guess the only people who could be bothered by it are the people who live there.

I don't think your title is grammatically correct. «very» starts with a consonant and therefore should be «Does it not pierce thy very heart?».

Does the OOM killer actually work for anyone? In every linux system I've used, if I run out of memory, the system simply freezes.

The massic heat capacity of water is 4184 J⋅kg⁻¹⋅K⁻¹. To heat one 1 Liter (1 kg) of water from 30ºC to 100ºC it would take 4184×(100-30) = 2.929e5 J. We want 4 liters however, so we multiply that by 4 and get 2.929e5 J × 4 = 1,172e6 J To then turn that heated water into vapor it would require some more energy. The vaporization enthalpy of water is 4,066e4 J⋅mol⁻¹, and has a molar density of 1,80153e-2 kg⋅mol⁻¹(so 4 liters (4 kg) of water in moles would be 4 / 1,80153e-2 = 2,22033e2 mol), which means that to vaporize the four liters of water we would need 2,22033e2 × 4,066e4 = 9,028e6 J (I think I might have made a mistake here somewhere, because I don't think it would only need 8 times more energy to completely vaporize the water, compared to the amount of energy required to heat it, but I can't find the problem). So the total energy to heat and vaporize 30 ºC water would be 9,028e6 + 1,172e6 = 1.020e7 J

Let's take a 55x40x23 cm suitcase. And let's assume a solar irradiance of 1000 W⋅m⁻² (which is what this site says is a normal solar irradiance to be expected on a clear day on the equator). Let's assume three faces are exposed to the sun and all equally so (three faces receive 1000 W⋅m⁻² while the other three receive none, which would not happen since on a rectangular cuboid, like a suitcase, you can't have all three faces facing directly towards the sun). The box would be receiving (0.55×0.40+0.40×0.23+0.55×0.23)×1000 = 438.5 W, which means that over one hour (3600 s), it would receive 438.5×(3600) = 1,5786e6 J, which is less than the required 1.020e7 J (by almost an order of magnitude), so it wouldn't be possible to heat and vaporize 4 liters of water in an hour.

What am I missing?

How will this offline translator affect Firefox's memory usage? The article mentioned that it currently only supports 9 languages. If I choose a source language will it be able to translate to all other 8 languages? Why didn't they use existing open-source software like Apertium (or did they?)?

He just so happens to be dead now.

The way you wrote it makes it sound like you were somehow involved in his demise. :D

Tate is a programmer?

They are classical elements, but it would have been funny if the movie had bromine and bismuth folk or something like that instead.

I like that the way you wrote it, it makes it sound like the adults need supervision from the kids.

Apple I think relies heavily on the BSD project (I think they might be even using the same kernel?) and Google on Linux. There's also probably a lot of open-source software they use behind the scenes or which aren't as big.

Closed licenses are arguably better for certain left projects

What about licenses that restrict the software from being used in a certain way? I think I've heard of at least one open-source license that disallows the software from being used in the military industry.

The ones surrounding popular open-source projects are often quite active.
