One place where a (doubly, perhaps) linked list might be suitable is when you have a list that wants to provide the following features: 1. Multiple independent (not necessarily concurrent, but not coordinated) mutators. 2. Insertion and rem

If s.index() returned nil, the "if" would test false and the s[i] would not be reached. The problem is that it returns non-nil, but the _limit_ is broken in this case: using s.endIndex as a limit means you can get non-nil but bogu

Well, "the grid" is not literally like "roads"; they have all sorts of difference in practice in terms of who interacts with them and in what ways... So equating them in some way is absolutely an analogy.

Ah, I misunderstood your comment. You meant "those retail customers who have fixed rates", but I read it as "retail customers, who have fixed rates".

The thing is, in the US the "sectioned off area of a bigger room" model of housing has been legislated and regulated out of existence. Similar for the other option the very poor (read: serfs) had in the Russia of the period Crime

Inheritances are not taxable (for the recipient), but IRS data shows similar patterns. What it really comes down to is that the upper tail of the "reliable income" distributions is thin enough that a large fraction of the people w

This is a very reasonable thing to fear. The concept of "уравниловка" in Russian exists precisely because the government tried to do just that in many cases. Making everyone the same (in terms of equality of outcomes) is a lot e

Medicare is reasonably cheap (assuming you paid Medicare taxes for at least 7.5 years; if you did not, it's at least $471/month). To be clear, "relatively cheap" is "at least $148.50/month; more if you have mo

In your analogy, where the grid corresponds to roads and railways, the equivalent of the supermarket or farm is a wholesale electricity provider or power plant, right? In Massachusetts you can absolutely comparison shop for specific power p

Not everyone agrees that disinformation should be curbed. And the reason many people, including the authors of the US Constitution, don't agree, is that they feel the risk of false positives is far too high. That is _because_ I have

That third link points to a survey by a bank that had 69% of respondents saying they had less than $1000 "in a savings account" in 2019. That's not the same thing as "in savings". "In savings" would incl

The US, which is what I have seen data for, is nowhere close to 100%. It's at ~75% per https://www.bloomberg.com/graphics/covid-vaccine-tracker-glo... Now some states _are_ close to 100%. Some are close to 60%.

While there was some pre-production, I disagree that vaccine supply is the only binding constraint we have going on. And the lack of sane regulatory approvals and sane distribution setups has been heartrending. If you look at https:/

Yes, if your app is a high performance server app, measure in that environment. But user-facing apps (the sort people run on laptops, say) have async I/O as table stakes, really. It's not even about throughput or CPU cycles: it&#

That's all fair, and your hypothesis is pretty much spot-on in terms of what happened. The huge productivity boost was basically key to the success of the project. I'm not sure whether the argument now comes down to "it woul
