Not only had the WTC previously been bombed, it was the same group who did it! Their goal to destroy that particular symbol of American commerce wasn't exactly secret. The success of the plan is what's shocking. The visual symbol

The article describes strategies to help when developing in weird languages. But they're helpful ideas for other contexts, too. When working with external systems or unfamiliar configuration formats, the same forces are at play. For i

What's nice about an ADT is that you can actually prove you didn't mess up the tag union. The trust you get from that is a force enabler.

I don't think I agree that we need three different things to handle them. We already have a general mechanism to convert an Option<T> to a T and panic on None, a method which shall not be named. So we just need get and get_unch

But in real code you never want unwrap, so why provide sugar for it?

I've come to believe ergonomics is a siren song here, mostly because recently I've been considering panics as forbidden as memory unsafety is... it's never okay for your embedded system or web server to panic, so don't a

Yes, Wrapping and Saturating very neatly provide behavior you might want in some context. I use them a lot in embedded contexts. Since indexing is nearly always fallible, it should be fallible!

No, I'd rather it not compile!

> Also it's worth noting that arithmetic is only checked against overflow when building in debug mode by default. Yes, the default behavior in release mode is even worse!

> Crucially, by grepping for `unwrap` and `expect` you can find the panics very easily. I write Rust code up and down the stack, and this is the thing that ticks me off more than anything else. You can get most of them looking for this s

In Rust code, if you're not able to locally reason that an array index is valid, it should be written with .get() and the None case handled appropriately. It's impossible to claim there's "no actual memory safety issue&q

I'd agree that often with new features and subsytems recent LWN articles are the best documentation around.

I've never seen an EDI implementation that required nothing custom. The claim is oft-repeated but based on little substance.

It's really amusing how people addicted to rich text assume plain text suffers the same limitations.

"my responses in red" assumes a lot about the visual abilities of the reader. I'm sure there's a better way to express this idea.

The comment you're replying to describes how they wish the world would be, after recognizing the reality of the world as it is. Tipping should be illegal. Tipping is necessary currently most places. Both can be true.

Yubikeys can be stolen... I take it from the GP's description the access is sensitive enough to require more assurance than that.

That being said, if instead of "use our custom app you've never seen to record a video" it's "just talk to a person with some standard video chat" then maybe it makes things a whole lot easier? But I don'

A simple workaround for the implementation is to redirect you to a URL with the code hashed as a query parameter.

Yes and misusing simple allegories and therefore misunderstanding the situation is very common.

Well this isn't exactly a currently-standing fence, so the metaphor falls down. It's more like someone coming upon their neighbor complaining about a mutual neighbor and their fence and offering them advice for the next confrontat
