A pretty straightforward solution is to have all your extensible options, etc., but also provide a few static objects with all options set to a working default. Use those objects for the hello world, or change the options you need to change

> So what you'll have to do is tell your teammates to not use nulls, and instead make proper use of option etc, and then you're back to avoiding NREs by conventions, not by the compiler helping you out. Am I incorrect in this?

In C#, null is just one possible value of the regular type Foo. The compiler cannot tell whether you have started returning null where you previously only returned non-null values, nor can it tell whether you've handled those null valu

In F# you'd normally use a type provider for this kind of work, but for the sake of exercise: type Chapter = Map<int, string> type Book = Map<int, Chapter> type Bible = Map<string, Book> le

Personally - this is a question of individual preference, though - I do not mind the OS boot time itself very much (to a degree). Whether the system takes ten seconds or two minutes from reset/power-on to the login screen does not mak

Pretty disappointing that it relies so much on comments. You can write an arbitrary 'polyglot' program in any N languages that have incompatible comment delimiters: just write the same program in each language and wrap it in the c

I am a layman to devops. By "ephemeral container data" do you mean temporary files created by the service, temporary files created by the OS / other applications, or something else?

You only need _one_ power user to disable the lock-in mechanism or to discover the security holes. After that, every user benefits even if they themselves cannot do such things. Of course open source projects also suffer from bugs and incom

That's true, but I would argue it's counterbalanced by modern apps being (for the most part) always online. While we have more control over what data they can access, there are far worse things they can do with the data we do choo

GNU seems to agree with you, since they categorised the right to redistribute on its own as freedoms 2 (original) and 3 (modified). Of course, they also "consider [all non-free software] equally unethical", so from their point of

I never quite got why GNU decided to consider the freedom to access the source code and the freedom to modify it as a single bullet point. To me, they're fundamentally distinct concepts, and furthermore the former is VASTLY more import

items.First()?.Data I think this one doesn't do anything because .First() will throw on an empty collection. The rest of your samples look fine to me though.

Ah, but you always have another choice. You can always surrender. Now, sure, you might be unwilling to surrender, and willing to risk a global nuclear war, over a direct invasion of your homeland. But what about, say, a covert invasion of a

Nitpick: everything you say is probably correct, but such performant C programming is also the very opposite of a "minimalistic and terse style". Which one is more minimalistic, 'new Foo' or a collection of various custo

Slight aside: please don't abuse the Elvis operator like that (by using it on every single nullable reference), it could easily grow into a widespread anti-pattern that makes debugging harder. My rule of thumb is that ?. is OK to use w

Yes, I was referring to the subject at hand - human achievement / technology / innovation - not making a universal statement about everything that may have limits. But I can see how my post could read that way. I'll make that

This is some of the shallowest, most misleading insight I've ever read. "Human achievement will probably reach a limit at some point" is effectively an empty statement. Even if you could take its truth for granted, it is comp

VSCode uses comments for every line in its settings.json file. I guess they figured it may not be correct JSON, but since they aren't sending those particular JSON files anywhere it doesn't matter?
