If you measure electoral college bias by comparing the vote shares in the electoral college tipping point state against those nationwide, the last 3 presidential elections with a Republican EC bias were 2016, 2000, and I think 1992. Had the numbers written down somewhere...

The same amount of money is available for transit construction projects ($2.6 billion) as in the Obama days. But under the Trump @FTA_DOT it takes local transit agencies more than twice as long to receive their funds. That's costly for them. usa.streetsblog.org/2019/07/…

There's been a bunch of discussion of "10x engineers" lately, triggered by a thread of nonsensical tweets from a VC. I think there is a reality that there are some skills that make some engineers much more productive at certain tasks than other engineers.

I don't know if the variation between people is variation in learning the design and details of the system, or variation in the underlying skill of mapping concrete examples to the system design.
2
I can explain that this skill exists, suggest that experience working through problems (both alone and with others) and learning the details of the system may help develop it.
1
As much as I can teach people how a system works, and walk through how specific examples move through the system, I'm not sure how to teach the skill of thinking through how a particular example is handled by a system.
1
And it seems like there's a huge amount of variation between engineers in how good they are at doing that or at least in how quickly they learn to do that when exposed to a new software system.
1
In other words, fixing a bug quickly often involves (a) having a mental model of what should have happened (through the software system) in the testcase and (b) observing (perhaps by testing variants of the testcase) in which part of the system things likely went wrong.

2
For example, I think one of the key skills for fixing bugs is being able to map specific examples (e.g., testcases for bugs) to a software design that you're familiar with. Being able to do this well makes fixing bugs much easier.

FWIW, I buy whatever is cheap ($50ish) and has good reviews on Amazon, in whatever color is rare and cheap (price often varies by color, and having a strange color is great at baggage claim). I get 5-10 years out of the resulting bags and am happy with my strategy.

And for some reason this is one of the states we rely on to pick the presidential nominees of the major parties...

Faregates in the city (or major stations), with no faregates elsewhere, is a pattern I've seen elsewhere. DLR in London. I think some of the more rural stations in Japan (although there most stations have faregates). Pretty sure another major one or two I can't recall now.
