Rails are indeed one of the cheapest, best scaling, and most reliable ways to move goods no doubt, but it also has a last mile problem.
Just wanted to point out the solution isn’t as easy as “rails all things”. Trucks still do offer some situational advantages, and will still have their place in logistics.
For Python, VS Code and Jupyter Lab. I used Sublime Text 3 previously but have found VS Code to be easier to set up and better supported over time. I do miss how fast and lightweight Sublime is this compared to VS Code though so I still use ST4 as a general text editor.
For Excel VBA (ugh), pretty much have to use the built in one as there doesn’t seem to be any alternative.
Oh yeah. This is quite fun, though once you hit level 4/5 some problems require fairly advanced algorithms / mathematics. One of the problems I gave up on solving on my own required knowledge of Polyas enumeration theorem to solve. Fortunately or unfortunately you can find some answers online, otherwise I would’ve never even known such a theorem existed.
For the tougher problems, expect a lot of graph theory / combinatorics, which I guess is the nature of Googles challenges as a search engine.
You weren’t kidding when you said it’s “very hidden”. It didn’t even occur to me that the greyed out “Community…” text was a search box. No borders, and the text formatting does not attract attention at all.
I think even a slightly contrasting background would / magnifying glass glyph would better indicate you can search there.
Fair response. It’s likely due to the lack of rail infrastructure why this delivery was “across the country”. Rails are typically much cheaper per ton-mile than trucks. If a rail alternative existed, I’m fairly certain the economics would have forced the use of trains.
However, I’d say the self driving part is still be a benefit that would improve truck utilization rate.
