I haven't drank all my coffee yet this morning, but are you saying that throwing a segfault can be a good thing? Either you unwrap the Option, or you have to remember to do an manual null check. The second option is more verbose.
452.
by cultus 8y ago
If you know something can't be null, then don't use an option. Simple as that. For example, a SQL library can return a non-nullable column of String as just a String, not an Option[String]. Thus, you actually get a solid distinc

The way Clojure handles nulls is ideal for a dynamically typed language. In Clojure, a nil is a perfectly valid object, and it is also a sequence (it's the empty list equivalent). That means that most standard library functions have no

A simple, safe way of tracking nulls like option is "CS theory going off the deep end?" Implicitly allowing all code to return nothing, and manually trying to remember what can return null and what can't, and checking that va

P-values are not good measures for reliability, because they absolutely are not the same thing as the chance that a result is wrong. This confusion, and ignorance of the prior probability of hypotheses is the reason why replication rates ar

So now you are saying that climatology is literally pseudoscience.

by cultus 8y ago
No, you aren't just disputing the consensus. You are claiming that climatologists "shut critics and skeptics" out of the field, so we shouldn't listen to them. Yes, they do shut out pseudoscience, as do other legitimate

You're really veering off into conspiracy theory territory here. It's clear you haven't the faintest how climate models or any geophysics works. Don't mistake a facility for computers for expertise in all science. I actu

That's uhh, not true. At any rate, shouldn't we be listing to the climatologists on this matter, because their specialty is, you know, climate?

Yeah, Go has some really fantastic aspects around tooling and a good concurrency story, but it's otherwise such a huge step backwards. I can't fathom the reason for not having generics. It's such a simple, completely common-s

Did you write type-unstable code? That brings Julia performance down and memory usage up, since things often get inferred to be Any. So, a vector of what you think are doubles could be turned into a boxed vector of Any. It will slow things

Well, it's a probability of the output given the fixed, fitted model parameters. This is the likelihood. This is not the probability of getting that output, since we don't know what the parameters should really be. See the inver

Yes, they wouldn't be normalized so you can't interpret it as a probability. Softmax is the function that normalizes it. However, even that you can't interpret as a probability of some outcome, because you do not take into ac

I am a former racer (cat 2). Every ounce does not count in amateur bike races, because such differences are dwarfed by differences in fitness. Significant figures. Aero drag matters a lot, and most of that is from the rider. Races sometimes

The vast majority of energy on a bike goes to aero drag, and most of that is the rider. Are you in a more aero position on the Merida? That would fully account for it. The difference in weight is not capable of causing much difference on fl

On a road bike, you will get a pinch flat from running tires that low, where the tube gets cut between the rim and the ground. Recommended pressure always varies. With wider tires, you typically must run them lower, since a too-high pressur

Stiffness in a tire is bad. That's why more expensive tires are suppler. Energy lost due to rolling resistance on a paved road is primarily viscous dissipation due to flex of the tire. If the tire is a stiffer material, this dissipates

by cultus 8y ago
Too high pressure actually decreases efficiency. While you have less deformation of the rubber, it causes the bike to bounce over irregularities more. The energy from this bouncing is lost. On rougher roads, often pressures below 90 PSI are
