I suppose ultimately the thing to test is application performance, (assuming you don't care too much about disk space). Because it depends on the access pattern. If reading and writing contiguously, then large record sizes (even if una

I know what you're getting at, I wondered the same thing, but my results were the opposite of what I expected for compression. I enabled lz4 compression and set recordsize for database datasets to 16k to match innoDB... turns out even

I find it useful to frame performance of pure software in two fairly distinct categories: 1. Efficiency, which I define as minimising losses i.e not writing things inefficiently, avoiding artificial complexity, bloat and keeping code simp

Wow, that doesn't sound like a terrible idea! Which is honestly surprising in this area where it feels like privacy, anonymity and human verification are incompatible with each other. I am trying to minimise my time wasted by websites,

Good catch, I misread that. Clock frequency is ultimately dependent on the longest path of propagation, so it does depend on the circuit, or CPU. I'd be interested to know from any experts whether there is potential for fundamentally h

Presumably everything in the chain, every junction, would also need to be a pure super conductor? Anything else would be susceptible to instantly melting or vaporising. So unless someone comes up with super conducting welding I guess that w

No, I'm suggesting that even with the worst possible fiscal punishment (even when it causes bankruptcy) it's still not enough, for two reasons: 1. If the damage done is so severe that it's impossible or impractical to reverse

Yes but that's only in terms of resolution, the interface is flat, i.e you don't explicitly ask for usr/sbin over usr/bin. The differences only become a problem with naming conflicts and misconfigured $PATHs.

Yeah, it's a strange thing for so many people in the right positions to have such a high degree of confidence in the problem and solution, have studies to back it up, and yet be essentially powerless in the face of cultural inertia and

I know what you mean, yet another tragedy of the commons. In the UK at least they are less common, I think it's partly a cultural thing, but I suspect road size and layout is also a significant factor, which negatively affects the prac

lol, a compression wall! sounds good, but is it?

by tomxor 3y ago
Walls have purpose beyond neatly cut lawns. This wall would work well at road field boundaries where a couple feet makes less practical difference than the large saving in materials.

Yup, the current dominating factor is resistance, not the Landauer limit. Biological systems supposedly operate at about one order of magnitude above the Landauer limit [0], i.e this is completely practical and has been happening before w

Kind of agree. The only strategy I could find was to not play pieces that make compatible future pieces less likely, mainly by trying to keep the surface as flat as possible, as soon as it gets real spikey you are not really making progress
