Pandas can be pretty fast, but DuckDB and Polars are both faster than Pandas. DuckDB supports vectorized and parallelized operations on Pandas dataframes, while Polars is written in Rust. I feel though the killer is that inner loop where da

I like both Python and Ruby and aesthetically Ruby is better and I can see why people are happier writing on Ruby. But to me happiness comes from achieving the ends — eg training a model, deploying code that impacts millions of people. I’ve

I’ve written Python for 18 years now and I’m certainly not unaware of its warts but its sheer usefulness and productivity makes it worth it. I see languages as a means to an end — some means fit people’s brains better — but at the end of th

It’s a hypothetical premium. Fares for the same route can differ between carriers depending on airport, time of travel etc. even among mainstream carriers. I would pay more not to fly Southwest.

Southwest is not a budget carrier -- they were never that cheap. But I would pay a premium not to fly Southwest. If there was Delta flight that was a $100 more than an equivalent Southwest flight, I would take the Delta flight. That's

I really dislike Southwest's boarding system. I set a check in timer and I still get group C -- after being bit twice, I decided to never fly Southwest again. SWA veterans tell me I need to be A-list but it's a chicken and egg sce

It would, but it would be super inefficient and slow. For smooth functions, gradient information gives more information about the search terrain. The more exact your gradient information, the higher quality your iterations become. On the ot

ML Models are usually used in the context of prediction, Y = F(X,θ), where X = inputs, θ = weights, F = model. There's typically no explicit feedback look (only historical data), no time-variation (you can add using lags however), and

I wonder if that would limit you to the very simplest of math. LaTeX notation lets you type math without the ambiguity of parsing text. And you can render a lot of it in Unicode (See Unicodeit.net). I would not want to type math in markdow
