People don't scan linearly; they recognise the pagination controls as a block. It's much quicker to jump to the end of the pagination block to find the "next" link than to scan through all of the numbers to find the curr

Seems I might be outdated, and ES6 does define an order.

by ajanuary 11y ago
JavaScript doesn't guarantee the order of keys. [edit] Also, the API makes less sense because JavaScript isn't statically typed so you can make up the result object on the fly. match('^(?<user>\w+)@(?<host>[

My understanding is that they were both, depending on context.

The advantage of foo/bar/baz is the cultural understanding that the contents isn't important. It's prevalence in programming is because programming languages have strict rules about where tokens are needed. We can't

Java defines the scope of a local variable to be "the rest of the block in which the declaration appears". The variable declaration is 'hoisted' to the top of the scope, which is defined as where the variable declaration
158.
by ajanuary 11y ago
I've never liked the phrase 'variable hoisting'. It implies the compiler actively moves the variable declaration. What's actually happening is lexical scoping - a variable declaration is associated with a lexical scope.

The website does a really poor job of emphasising that it's using asymmetric cryptography and some sort of challenge/response protocol, and how that is really where the improvement over the status quo is. It's _not_ just send

I don't know that "semantic" is what you mean here. Semantics in HTML is about exposing the meaning of content through the DOM. Adding data-binding via attributes doesn't change that at all. <label>Name <i

Temporary plaintext passwords are rare; I don't think I've ever seen one. If you've got as far as temporary plaintext passwords, I'd argue it's a better UX to provide a simple link instead of forcing them to copy an

When implemented correctly, password reset links a) Work once. If you click on a password reset link and it says it's already been used, you know something is up, v.s. someone using the plaintext password to log in before you and you a

It wasn't the case here, but Oracle effectively treats empty string and null as the same value.

Ruby (and most languages) evaluates the arguments before passing them through to the function. So it first evaluates server.accept, which blocks until a new connection, then passes the return value through to Thread.new which spawns the new

The "/" is automatically added after you type the month, so you're never left with "0515". Try out the demo [1] and it should be a bit clearer. [1] https://s3.amazonaws.com/gabe-cc-form/ind

It breaks down as soon as you reach a single layer of nesting. (a + b) / ((c + d) * e) would be (with pure whitespace) a+b / c+d * e you'd probably end up mix-and-matching a+b / (c+d * e)

iOS doesn't expose the necessary APIs to be able to filter calls.

If you attacked that formulation with the normal assumptions for logic problems, the answer would be the same. If you break the assumption that you can trust all logical statements in the problem, regardless of their origin, then you could

by ajanuary 11y ago
I'm not convinced the fact one label "challenges" the other should change how you attack the problem. I think you have to be able to apply the same reasoning to the following problem: James says he is shorter than Alex.

by ajanuary 11y ago
With logic problems the assumption is that logical information is always relevant to the solution, no matter what the source of the information is. It's interesting to have that assumption challenged though. https://www.yout

I've been pretty vague which probably isn't very helpful so I'll try to be a bit more precise: for a mutable implementation it's quadratic in the number of times render is called over the lifetime of the component; for a

by ajanuary 11y ago
That doesn't help reduce the computational complexity in this instance. After appending, the lists are different, so it renders the component, which starts iterating the children and checking each one in turn to see if it's change

by ajanuary 11y ago
Yup, there is a bunch of things you can do to reduce the constants, but even with chunking the computational complexity is the same. In this case, it's not hard to reduce the constants to a point where the complexity doesn't reall

by ajanuary 11y ago
It still needs to compare them, it will just do a reference comparison rather than a deep comparison on the fields. So again, it will be (a lot) quicker, but the complexity is still the same.

by ajanuary 11y ago
How does ImmutableJS work? If it was turned into a straight list of immutable records, each comparison would be quicker but the complexity would remain the same. You'd have to something like turn it into a tree to reduce the complexity

It's called at different times so will return different values, which is important.
