Pandas isn't the problem, the problem is assuming that "$LIBRARY releases the GIL so things will be fast!". It's a pennywise, pound-foolish approach to performance. Someone will write a function assuming the user is only

Because you’re using Numpy via an intermediate library like pandas and you have composite data in one column?

by weberc2 8y ago
Not everything is amenable to numpy and it's pretty easy to make performance worse by throwing numpy at every problem. For example, if your array contains Python objects that are part of an operation, you've likely just introduc

Even if your app is IO bound, Python's concurrency is painful. Because it's not statically typed, it's too easy to forget an `await` (causing your program to get a Promise[Foo] when you meant to get a Foo) or to overburden yo

You're supporting the parent's point that it's contextually dependant.

It's not possible to communicate the full nuance of any ideological group, especially not in every HN post or tweet. We need meaningful definitions even if these definitions don't 100% apply to every individual in the group. And w

Disclaimer: As mentioned elsewhere in this thread, I don't particularly like the term "SJW" for its pejorative connotations, but I'll use it since it's the established term in this thread. It's not an opinion,

by weberc2 8y ago
Earnest question--what is the non-perjorative word? "Progressive" is the closest I've found. I genuinely want to debate ideas, but I'm not sure what the most precise term is.
972.
by weberc2 8y ago
I agree that we need a better term, but I don't perceive it as being co-opted by the alt-right so much as a pejorative that gives the user an air of bad faith. I want a neutral label for people who advocate for race/gender caste s

There is a difference between making observations about different political ideologies (what the parent was doing) and advocating for the establishment of racial, gender, etc hierarchies (what "SJWs"--for lack of a better term--do

Can't speak for OP, but Social Justice (tm) is mutually incompatible with social justice. The former is roughly a movement to establish identity-based hierarchies while the latter opposes these hierarchies. So when people say they&#x27

The startup costs are fixed (they don't increase linearly with the number of loop iterations) and for such a small program, they could not reasonbly explain more than 1s of the 20s gap between C and Java. Also, I don't think it&#x

Are you opposed to all kinds of intellectual property protections or just this one domain? In particular, why should anyone put R&D into developing better varieties of crops if their innovations aren’t protected? Or perhaps improving cr

I'm not sure if you missed my distinction between far-left and moderate-left or if I'm misunderstanding something about your response. I agree that these institutions have long been left-of-center, but they used to be liberal (i

Yeah, I'm not sure that "far left" is the appropriate term, but I wanted to communicate "people to the left of moderate liberals". I'm thinking people whose "egalitarian" vision demands segregation an

Agreed, although the right-wing echo chamber is rightly marginalized (in the literal sense of the word), while the far-left are running newsrooms, universities, associations, corporations, public education, etc. I don't think the far-l

Granted, it's not a general purpose programming language, but it has a comparable learning curve. Certainy many times steeper than YAML or JSON or other markup languages.

I did some profiling too--I shaved off 10-15s by using the C xorshift implementation instead of rand.Float32() (which spends a lot of time locking a mutex).

I rewrote the Go benchmark to be a mechanical translation of C and it performs much better. C (gcc -O3): 23.8s Julia (julia 1.1.0): 32.8s Go (alt) (go 1.12): 39.3s Java (java 1.8.0_60): 44.2s

It's surprising that the optimized C is slower; it's much faster on my machine. Like 20s (optimized C) vs 1m20s (unoptimized C).

I'm 99% sure the Go version doesn't allocate any vectors; afaict, it's passing everything on the stack.
988.
by weberc2 8y ago
The Go version spends 8 seconds writing data. This is probably par for the course for most implementations.

by weberc2 8y ago
Those are copied on the stack, not heap allocated, so the GC wouldn't come into play.

by weberc2 8y ago
I modified the Go version to pass references (see my second edit) and that made up the difference (or I mistranslated).
