Crystal’s syntax is similar to Ruby’s, but AFAIK the similarity more-or-less ends there.

You’re right, of course: even Guido seems to have been moved off working on CPython and onto some tangentially-related AI technology. However, Faster CPython was supposed be a 4-year project, delivering a 1.5x speedup each year. AFAIK they

PyPy is a fantastic achievement and deserves far more support than it gets. Microsoft’s “Faster CPython” team tried to make Python 5x faster but only achieved ~1.5x in four years - meanwhile PyPy has been running at over 5x faster for dec

Fundamentally, CPUs use 0-based addresses. That's unavoidable. We can't choose to switch to 1-based indexing - either we use 0-based everywhere, or a mixture of 0-based and 1-based. Given the prevalence of off-by-one errors, I thi

The reason many languages prefer `length` to `count`, I think, is that the former is clearly a noun and the latter could be a verb. `length` feels like a simple property of a container whereas `count` could be an algorithm. `countof` remove

Yeah, you could argue that choosing C is just choosing a particular subset of C++. The main difference from choosing a different subset, e.g. “Google C++” (i.e. writing C++ according to the Google style guide), is that the compiler enforces

There’s also CimGUI. I know the underlying C++ library is well-regarded - I’m curious to hear people’s experiences using the C wrapper. https://github.com/cimgui/cimgui

AFAICT Python basically is a [statically-]typed language nowadays. Most people are using MyPy or an alternative typechecker, and the community frowns on those who aren’t.

Mruby isn’t aimed at embedded systems, it’s “lightweight Ruby” intended to be embedded within a lower-level application. The language it’s most similar to is Lua. My gut feeling comparing the two is that mRuby is a better (or at least less

How alike actually are Ruby and Crystal? I’ve heard the similarity is only skin-deep: similar syntax but quite different semantics. In other words, isn’t describing Crystal as “Ruby with types” similar to describing C++ as “JavaScript with

Unladen Swallow got a lot of hype but was only a very small project. IIRC the only people working on it were two interns. V8 was a much higher priority - Google hired many of the world’s best VM engineers to develop it.

True. Choosing between the two languages usually comes down to their library ecosystems - or more bluntly, to Rails on one hand vs NumPy on the other. Nonetheless, it's still common for people to talk about the relative performance of

If valid `data` can be zero, an empty string, or anything else “falsy”, then your version won’t handle those values correctly. It treats them the same as `None`, i.e. not found.
