I recommend ignoring transducers unless you know you really need push-based iteration, which probably isn't the case. Generators are generally a superior approach otherwise.

Why should the majority have to bother with ‘radically new’ when ‘same old’ is still chugging along with superlinear growth?

Medium lets writers opt-in to a paywall. It is not the default, but does come with some perks for authors.

What GOFAI technique got even close to 80% of the way? Maybe pathfinding, if I'm being particularly generous?

I've been a proponent of radix sort since long before I'd heard of this package, but I think you've completely missed my point.

Sure, I think the point of measuring CPU speed is not to say that it suffices for a fast boot, but to say that whatever it takes to boot, the CPU should not be a limiting factor. When I think of all the things necessary to booting; discover

Even ‘perf stat libreoffice ./somedocument.odt’ give an IPC of almost 2, and that's hardly a well-tuned computational workload. > And mostly software doesn't utilize multiple cores well. Most software sucks, that's th

That was my point, yes. Being unnormalized is a good thing. IEEE does the same thing for their decimals. > (In fairness, for small integers, the operators over normalized values are closed — they always return normalized values) Normally

10⁹ ops/s is an incredible underestimate; CPUs tend to have an IPC around 4, and at least two cores, even on mobile. Which means at 3GHz, you should have closer to 10¹¹ ops/s. The real question is not whether a computer can boot i

This is true, but hardly important. Multiple representations hurt because they waste space, not because they're transiently evil. If you're scared of normalizing before comparisons, or somesuch, nothing stops you normalizing aroun

No, most numbers have only a single representation. A tenth have two, a hundredth have three, etc.

That's not what the quote means, really. They have best-in-class performance on both single- and multi-threaded workloads. It is just saying that the allocator supports a deferred_free callback, which is zero-overhead in the fast path

There are a lot of ways to write the same story; Mimalloc has a few innovations of its own, has good benchmarks to justify them, and the paper is a very good read. In particular, Mimalloc works to increase data locality, by using per-‘page’

Unless I've understood you poorly, this is confused. The issue with CMOV is primarily that it's a three operand instruction. If it was a two-instruction operation, it would just be arithmetic, and nobody would care. A minor, secon

A Lua REPL is hardly worse than a Lisp one. > something like `eval` which is not compilation thus inferior I honestly don't know what that means. Turning text into code is compilation; there is no difference between the two in tha

The point my first comment made is that you don't need to analyse a query at runtime, you just need to provide functions. I will agree again that Lisp makes REPLs easier to write than does C++, but a CL with Lua syntax could still, jus

I'm not sure if I'm missing something, or if this is meant to be allegorical for some other, more difficult problem, but the argument here seems very strange. For sure, C++'s string handling is an awful sight, but the jump to

Generally, precision is pulled on-demand, as it is needed. If you compare two values as x < y, x and y will be evaluated to higher and higher precision until the answer is unambiguous. This can be an issue if the values are equal, since

Could you be more specific? What are you doing on a RISC-V board where emulated popcnt loses more than 10-20% of your performance?

What's the rush? The instructions can be emulated in the meantime at a passable speed.

I'd recommend a Gameboy Advance SP, because the older, non-backlit, screens were genuinely poor under some non-ideal lighting situations, and you still get support for older generation games. But a standard Gameboy Advance or even Game
