The postgres query optimizer will try to minimize the number of pages read from disk (and the number of intermediate pages written to disk). Benchmarking the query optimizer by mak…

A government's primary purpose is to act on behalf of its constituents, and if these daytrippers are substantially detrimental to Amsterdam's livability, they should be discouraged…

Fly postgres is not managed postgres, it's cli sugar over a normal fly app, which the [docs]( https://fly.io/docs/postgres/ ) make quite clear. Their docs also make clear that if y…

I would substantially nuance most of what you say. I really like vim and use it almost exclusively, but it is not necessarily the "only" way, or even necessarily the "best" way to …

Space is not quantized, so yes, the electron has infinite possible locations. There are, however, places the electron cannot be, depending on its energy. See, the electron's energy…

I personally really like using Rust, but I don't think it's necessarily better than go. There are some areas where Rust will definitely be better or more ergonomic, such as bare-me…

Let's do a little calculation. For an upper bound, let's say you press your full weight onto it and the coffee grounds' resistance is not the limiting factor. That's maybe 90kg, ti…

It depends. For operations or aggregates on a single field, it improves cache locality, whereas if operations act on all, or most, fields of the struct, it hurts cache locality. Th…

The quote "Efficiency with algorithms, performance with data structures"[1] is very applicable imo. [1] https://isocpp.org/blog/2014/12/efficiency-with-algorithms-p...

Matrix math in python is a bit clunkier, because matrices are not native to the language. That said, numpy, the standard for matrix math in python, is quite nice. Its documentation…

K-9 Mail really is the grandfather of powerful E-mail apps, but I have switched to Spark a few years back when it became available for Android and never looked back. It's just a br…

I just use two or three drops of water from a pipette, which for some whisky really opens up the flavors. Most of the improvement for me comes in the form of mouth feel (it gets a …
