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 making the shared buffers large enough to hold all the data the

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 from going there. Or, to put it in more financial

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 you run postgres in a single-in

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 do things. If the vim grammar clicks for

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 is quantized, meaning it can only have a predetermined

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-metal or low level systems programming tasks, but ma

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, times the acceleration of gravity, for abo

Elderly people also use bikes and often transition to electric bikes or sometimes tricycles if needed. As other people have commented, public transportation in The Netherlands is also quite decent, so that also sees much use by the elderly.

The problem of dangerous interactions between drivers and cyclists is much smaller here in the Netherlands, mainly due to two reasons. The first reason is the infrastructure, both visible and invisible. Separated bicycle lanes are commonpla

Years ago I stumbled onto competitive Tetris because the YouTube algorithm pushed the Jonas vs Joseph match on me. I didn't expect it to be exciting, but it was actually captivating and I've followed CTWC (very) passively ever sin

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. The exact same tradeoff differentiates OLTP (transactional&#x2

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 is, imo, miles ahead of matlab's and the APIs are a bi

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 breeze to use. Sure, I have some gripes with it, but I re

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 bit more viscous and smooth) and in the nose. Anything more

I find the interface of GitHub (and therefore gitea) much more usable than gitlab's. Gitea is also easier and lighter to self-host than gitlab. Gitlab's CI offering is awesome though and really makes it stand out among software fo

First things first, I think companies should be up-front with their customers. That means not marketing non-AI solutions as AI. However, lots of companies do not sell AI, they sell a service. And as long as that service is good, it should n

I think the point here is that your MVP should behave like the actual product in the eyes of the customer, but you do not have to actually build the functionality. By providing a lot of the service manually, you can get your initial custome
