Depends what you mean by “custom types.” Elixir supports structs, but they’re not really as rich as classes in another language, for example. If you just want to write type signatures for your functions though, this is a pretty good guide:

Maybe it does, maybe it doesn’t. Maybe somebody gave you a keyword list that they thought had unique keys and it didn’t. The point is, the two structures are not semantically equivalent, and I think it’s a mistake to conflate them in genera

The work scheduler example involves writing a work scheduler, though :). The logic is going to go somewhere, is what I’m saying.

Well yes, because not finding a key in a map is not an error typically. Map.get is the same way, as is Access. It returns nil. If you want it to be an error you can use the version that raises.

In Elixir’s standard library at least, it is pretty consistent. Functions that can fail return tagged tuples, and functions that will throw when they fail end in !.

I would recommend writing specs for your functions and using Dialyzer, too :)

The scenario is not invented per se, it’s something that really happens sometimes. Maybe the systems you interact with never return malformed data more than a few times, but the ones I work with do. Throwing an exception on a deserializatio

I disagree about not using the module-specific `get` functions. They should be used when you expect what you’re operating on to be a specific type. Sometimes I want to write a function that only operates on maps, and Map.get will throw an e

Which other ultrabooks, specifically? It’s definitely not all of them, if you’ve been reading the benchmarks.

It’s open-source, and the author has a long history of supporting his product for free as an ethical good, even while some of his collaborators have went commercial and cashed out, once even taking the project name.

If you thought a MacBook Air was going to replace a purpose-built machine learning workstation of course buying it would be a mistake, because it won’t do that. It only supports up to 16GB of RAM! But what other computer in that form factor

I believe it was tptacek who once commented half-jokingly that the ideal thing to do would be to leave the API open to uBlock Origin exclusively and kill it for everything else. The privileges required by that extension and others like it a

This is an epistemologically leaky argument. The goal of an Alzheimer’s drug is not to reduce amyloid plaques, it’s to treat Alzheimer’s. There is, as of now, no evidence that it does so. Giving people false hope of treating a horrible dise

They have failed to prove efficacy in a trial. Why believe it has a 3% chance of working? Do you think arbitrary chemicals have a 3% chance of curing some disease, even when it has yet to be shown? There’s absolutely no reason to believe th

Well past a certain scale you almost certainly have infrastructure that isn’t an iOS app.

Sure but that's nothing like deterministic destruction, where I can tell you the order that things will be deallocated just from looking at a block.

M1 Macs can already run iOS apps.

How is RC deallocation deterministic? Besides which I don't want to have to keep track of weak references, at that point I would rather just have a full ownership model: https://github.com/apple/swift/blob&#x2

Swift is currently reference counted, which is more or less GC but worse because it’s not tracing/cycle-detecting.

Absolutely, but that doesn’t mean we shouldn’t be trying to resolve problems all the same. Teams not having control over their work is inefficient.

I wouldn’t choose it because I don’t like it. I’m not going to change a housing situation I like a lot just to make it easier to work from where I live. That’s the opposite of work-life balance, to me.

Yeah, I have to work in the same room that I sleep in, and I only have one monitor and one desk.

It’s funny because I feel like I’ve been reading article after article recently about how working in offices is dumb and they can’t imagine why anyone would do it anymore unless they were zombified corporate stooges. My feeling is that work
