Won't pass code review till you can use dependency injection to pass a + operator mock for testing.

The memory comment certainly raises questions. Tagging pointers on 64bit ARM does allow some new techniques for compactness but it'd be hard to claim this overcomes the doubled pointer size. Does anyone have data on how memory use was

Couchbase may have involved the creators of Apache CouchDB but they are only lightly related these days (mostly some remnants of replication and map-reduce concepts). Both have move some distance since then so it's best to assume that

I'm pretty sure this doesn't measure what it claims. It's a mostly sequential flow with very little meaningful concurrent work going on. I would imagine a for loop would put all of those to shame. I'm not sure why anyone

This. Behavior is much better these days but dirty schedulers and ports are still the first places to consider putting C code. Only when you know you've got a solid implementation should you upgrade it to a NIF. A short note on how har

Good point. I guess I find it like a hybrid where you don't benefit from the cooperative side and don't achieve true preemption. I think either end would be better than keeping the middle ground.

As far as I understand, you can make an actor reentrant which frees the thread. It's definitely a leaky concern compared to Erlang's process implementation.

That's an interesting point. One of the nice things about immutable structures is that old things can never point at new things. (Some might exploit laziness to allow some sort of loop but I'd count that thunk as a mutable structu

That's not quite what I meant. By text parsing, I mean sending a big string to the DOM like: elem.innerHTML = "<p>Example. Please parse me.</p>"; That's going to take more time than carefully co

I never said it was necessary. I am mainly pointing out that there are similarities in the mental model of the original comment and the virtual dom. Of course there are many ways to get results. The virtual dom seems quite nice since it avo

I think it's a valid view if you consider that the rendering is one-shot. All input → entire document. There is no concept of update during a server side page rendering, which is quite similar to how the mental model for libraries like

I think the iPhone 4 is from 2011 so roughly 4+ years old. With safari though, I'd also be interested in knowing the iOS version.

These come to mind: rebar3 (Erlang), mix (Elixir), composer (PHP), elm-package (via elm-stuff/exact-dependencies.json).

Display technology also varies quite a bit. Some cheaper devices tend to saturate certain hues like redness. It could very well look a bit more orange on one display and look completely yellow on another.

Not sure why this got down voted. It's easy to see that points can be selected between two others that are parents in some cases. With mid-points, it usually mixes a fractional part like taking a midpoint 1/2 and then moving the u

Fair enough. Getting a usable API that works reliably here is tricky though. I've often fallen back to a sort of indirection like "move this card right after that one" ... this only works if you can calculate that right away

I think it relates to the idea that "Object Oriented" meant message passing (methods) between entities (objects). Not the meaning that was derived over time as programming languages borrowed select ideas from Smalltalk and then co

If you can sort fractions and call a function to get something between two points, then that's the entirety of the complexity. The "library" is about a hundred lines in JS and less in Erlang. The logic, which I have written i

Yes. This is very similar if you consider the path on the b-tree with the alphabet L, R. It doesn't follow traditional lexical sorting though since RRL (5/2) comes before RR (3/1). This is handy though. Consider having someth

Sure, you'd need a library but the problem with integral sorting is that operations must be totally ordered. This starts showing limits under stress of heavy collaboration. There is more than one way to solve this but most solutions ei

I'll wrap up a new version of the library that's independent of what I have it hooked up to and upload it to npm and hex.pm respectively. When I first wrote it, I started with midpoints but it doesn't take long to see that it

Growth is one, the average term will be smaller. The real reason to pick this is that the tree is a b-tree so you can pick terms above and bellow, so you can end up with simpler terms, not just more complex ones.

You can get much farther by storing a fraction. Still, a midpoint is not the most effective point to chose. One solution I've explored is in the form of fractions generated by the Stern-Brocot tree. The continued fraction representatio

They started with a version of ejabberd of some sort and migrated to more custom components over time IIRC. I can't find the link right now. (Keep in mind that ejabberd is written in Erlang.)

Yet composability is exactly what makes it easier for humans to reason about. It's the small surface of a composable part that fits into more immediate representations in our mind. Whether or not it's natural mapping functions to

The syntactical building blocks might be similar but the execution model differs. While you could obviously achieve any sort of term evaluation with a metainterpreter, the TRS in Mathematica offers a rather smart rewriting system. It can ea

Flow offers some interesting control over things like optional types (nullable) and intelligent understanding of type tests in conditionals or calls to libraries like invariant. I've had these sorts of features catch quite a few bugs i
