Saves $40/mo for as little as they have to do at my bit of the street.
You might want to check on if they have a "per bag" rate (probably unadvertised). My parents switched after they found out about it and save quite a bit every month.

The point that confuses me is: the energy on the outside lens surface can't light a fire, but the energy produced by the glass can. What work was done on the outside energy? It was redirected inside the lens, but how is that work? Doesn't work in thermodynamics reduce to the lifting of a mass in a gravitational field? How is the lens doing any work, in that sense?
There is (approximately) the same amount of energy on both sides of the lens (presumably a small loss into the lens itself). If you measure that energy directly off of the lens on both sides there won't be much difference (you can touch both sides of the lens without getting burnt), but because the direction of the energy has changed, the density of the energy at the focal point is higher than at the lens. So, there is more energy per square mm at the focal point, and presumably less energy per square mm in the area around the focused light than in the ambient area unaffected by the lens shadow (I wonder if that is measurable).

The healthiest diet is what your body needs, and what your body needs depends on your individual body chemistry, your environment, your lifestyle, and probably a half a dozen other factors.
You seem to be implying that we can never know anything about diet because each specific case differs from the general case. That seems to be a fairly pessimistic attitude regarding the ability of experimental science to tease out commonalities and processes in human biology.

it also leaves millions directly controlled by the government — such as pupils in government schools [nytimes.com] — without choices at all.
...
and parents, rather than the Federal government, be allowed to control the children's nutrition
You realize that the existence of school lunch standards does not preclude the parent from packing a lunch for their children, right? The school lunch program is not shoving food down the kids' throats. If you want your kid to have whole fat, white milk, then pack it for them.
I do agree that the standards are wrong in places, maybe in lots of places, but the existence of those standards doesn't take away parental choice and responsibility.

That should give officers incentive to ensure their cameras are in working order.
And encourage miscreants to find ways to remotely disable the camera.
I actually agree with your statement, missing camera footage should be treated as destroyed evidence (which, as I understand it, is treated as if it would support the other side). But there is potential for abuse on the other side, also.

And as in real life, the only way to deal with those people is to physically remove them from the conversation. That is, have a moderator whose job it is to delete the posts and evict the poster, even if it is a throwaway account.
Threading helps, too. It is a huge pain to try to follow a conversation on an unthreaded comment system.

I would actually like it if all commenting interfaces gave up, and we fixed netnews,
I agree with this, I would very much like to be able to use a preferred, threaded client with offline capabilities.

We need thinkers who can define requirements precisely, designers who can describe processes to produce those results, and then turn the design (UML. Warnier-Orr, Flowchart, etc.) over to a generator
We already do this, that generator is called a compiler. By the time you have specified a design to the same detail as an engineer specifies a bridge you have already written all the code. Engineers specify a design down to every individual bolt. Software specifications do not design down the individual line of code. This is the difference between engineering and programming: in engineering when a design is completed then the object still has to be built, in programming when the design is completed then the program is done.

Old programmers never die, they just hit account block limit.
