That is not how trackers work. Most trackers simply operate by relative gas expansion. The sun heats one side of the horitontal tube/bag more than the other due to position, and that causes the tracker to push the panel in the right direction. No motor, no eye, almost no moving parts. Not at all over engineered

You make this sound simple. You are glossing over a lot of detail that requires non-programming skill. Especially given he is clearly trying to avoid a management role, why eould you even suggest this? At a minimum, he needs to understand the business and managerial and risk mitigation functions he will need to play, in order to determine whether he has the skills required and desire to play those roles.

I do not follow your comment. I do not know what it means to charge different portions of a battery at the same time in parallel. Either they are connected cells into a single battery, or they aren't. If they are connected, then there is only one battery and your comment doesn't make sense to me. I think gp is correct that we are talking higher current.

Because they last 200k miles with minimal maintenance? I own a 2004 3-series with 160k miles on it, and it is the cheapest car when converted to $/yr I have ever owned. I have learned that the crap you are spewing is all manufactured perception, and likely the new iteration of "buy American" (which is really "buy union", since "foreign cars" are just built in the southern U.S. by nonunion factories).

that's all great, but accepts the premise that it detected anything. i could have a program that emails myself every day reporting an ebola outbreak and eventually i would have completely destroyed both the WHO's announcement speed and these clowns. of course, that is absurd, because the number of false positives is huge. and this is absurd for the same reason. there is zero information about false positive rates, and without that this "news" is saying absolutely nothing. the journalists, as usual, are complete fucking idiots who can't process basic logic, and as a result it seems like they are pretty much reprinting the press release from the group that developed the system (who should, and probably does, know better).

No conspiracy required. A bill that very few people know about and far fewer would actually have affect their vote pattern or donations has very little chance of going anywhere. Every bill is an opportunity for riders and house-senate conference shenanigans, so I am pretty sure things are working correctly when this goes nowhere.
