Trains are good, realize there's basically 5 levels of train (with last 3 leaving from the major train stations):
- Metro
- RER (faster than metro)
- Transilien (Ile-de-France region's trains)
- trains from other regions that go to paris
- national trains (Intercités, TGV)
- buy bread from a bakery that has a line (locals) out the door at 7:30am on a Sunday
- many fantastic day trips outside Paris. Versailles likely *mobbed*; alternatives: Fontainebleau (palace+forest), Chantilly (chateau & Musée Condé), or towns like Chartres or (further) Troyes
- walk around old parts of the city (e.g., the Marais (e.g., rue des Rosiers) & Place des Vosges, rue Mouffetard)
- if you're there in July/August, see less popular attractions, e.g., Saint-Denis Cathedral (a bit out of the way), church of Saint-Germain-des-Pres (renovations??)
Do the police have a non emergency number for that sort of thing? I've observed people calling such a number for that... and the police towed the car away 15 minutes later.
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...
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.
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.
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.
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.
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.
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.
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.
