The article described the type of situation this arises in: when you want to use arbitrary data as keys of a map, for example when grouping a collection of objects by one of their properties. Any implementation of a hash/map/dictionary should support this process, whether or not it coerces the types of its keys.
The problem with the engine in question is that it makes a hash change its behavior when all keys are integers.
I feel like an alien reading an article like this.
The idea of "showing off" with vacations, weekend events or even professional accomplishments seems preposterous to me. How is this socially acceptable is beyond my comprehension.
Likewise, I'm probably only interested in knowing where 10 or so people spent their vacation, and even then, only when the narrative is directed at me or a small number of friends. I can't understand how a public parade of general info and photos can be anything other than utterly shallow and boring.
I feel alien reading this too and I have ~500 friends on Facebook.
I don't see people doing anything like this. Maybe I'm selective but really next-to no friends share their consumption. I think the share-your-sunsets-and-dives-into-waterfalls is the movie version of Facebook. We wind up sharing cats, snark and sad moments.
I feel this, 32M with kids. FB usage by actual friends that I cared about fell to zero and my feed was full of shallow experiential grandstanding.
Deleted my FB account but copped a hiding from the silent majority for being 'hard to get in touch with' and feel a bit guilty about this but overall life is better without FB or any other form of social media.
True experientialism is being there in the moment, not standing outside carefully curating the moment for others to gawk at.
Text is consistently better in Safari in subtle ways.
It's one of the reasons why I still use it, even though it keeps getting worse with every release (crashing tabs, DNS resolution issues and that dreadful new inspector to name a few). Such a shame, it used to be a great browser.
