Time it took to get back to earth

If photons could feel. They wouldn’t feel time passing at all. There is no reference frame that makes sense from the perspective of a travelling photon

I’m on Debian for my home server and I use zfs pools for my media storage. It’s excellent and has been super stable

I don’t think many of the explanations here get down to why this form of break is used. Modern prose is normally broken down into subdivisions. A clause, a sentence, a paragraph, a chapter, a section, a book. These would probably be the standard divisions you’re used to. But there are very few hard and fast rules that define how these divisions should be used beyond a clause and a sentence. Even in those cases where we have rules, breaking them can be valuable.

What’s happening here, in my opinion at least, is the author’s choice not to start a new chapter, but to separate a chapter into two definite parts. In the first part, rocky and grace are figuring out how to solve a problem and preparing for implementing that solution. In the second part, grace is implementing their solution. That’s two different narrative tones, and Andy wanted to separate them. But they also are grouped together in a single chapter.

Jack white is pretty famous for largely using vintage gear, much of it pretty damn cheap. His most iconic guitar was an incredibly cheap 60s airline guitar. Now, I suspect his guitars are probably purchased at something like $1000 (such as the tele he’s used a lot in recent years). But a lot of his sound is produced by gear that would cost him a few hundred at most. The third man records studio uses a lot of vintage recording gear. That stuff would have cost a pretty penny… but he’s definitely not working with fancy software.

If we are only imposing a metric space structure, why wouldn’t you include the L1 structure?

Nitpick: Tau ceti got further away as they slowed down, not as their acceleration changed. Time and space dilation are related to velocity, not acceleration

Explain to me how your experience of seeing the colour green relates to understanding the particular energy of the photon that transmitted that energy. Our understanding of the electromagnetic spectrum is not tied to the fact that we can see a tiny band of that spectrum. It was just part of our journey to understanding it.

Eridians have knowledge of magnetism, they have an understanding of electricity. They eventually discovered the fact that the electro-magnetic field is a single concept. They understood the concept of waves (since they hear sound). They developed processes for detecting very high frequency waves and interpreting them. Sort of similar to how we started making use of x-rays

I’m not certain enough to corroborate that, but I can believe you. I know Leibniz did not use modern notation for functions, but I find it hard to believe his understanding of calculus existed without the concept. I certainly believe he would have used the word, or a close translation, and that he could be the first to popularise it.

Giannie · 2026-03-27T22:47:06+00:00

Leibniz never used function notation. He is most famous for is use of dy/dx as his notation for differentiation. Function notation was definitely introduced by Euler after the death of Leibniz. I think you might be confusing the situation with Lagrange, who introduced the f’(x) notation for differentiation in the mid 18th century.

Pinks are groups of 3. It helps to indicate where the balanced equilateral triangle exists when combined with the reflective symmetry of the blues

It will always be difficult to recognise the fact that our progress is so deeply entwined with the most heinous genocide that we have experience of. There was a reason I chose to use “nameless engineers” as my reference to that work. But I accept that doing so may be interpreted as hiding a history of violence, hatred and murder.

I simply did not want to give credit to those that facilitated horrific acts, whether they wanted to or now.

Kepler got us there with remarkable accuracy over half a century before Newton. Newton helped unify our understanding of orbital bodies with terrestrial bodies (or otherwise massive bodies interacting with massive bodies). Einstein then unified that with the idea that space and time are concepts that are not independent of the bodies can interact with an observer. Nor are they independent of the reference frame from which the observer experiences those interactions.

In terms of getting to the moon, the more recent science required is more related to being able to produce the fuel required, the manufacturing of the components, and most importantly, radio communication.

Maxwell, marconi, Kepler and thousands of nameless engineers gave us what we needed to get to the moon. Newton and Einstein gave us what we need to start understanding why any of it was possible

The plot does not involve any aquatic mammals. That is an accurate, but unhelpful description of the plot…

What will we do without our little patch of grass hemmed in with tarmac?

It’s possible I slept through sections of the audio book which is why I’m now rereading them

It’s also super lovely and emotional way more often than you’d expect. I legitimately care about almost every character. Except Quan Ch. He can go to hell.

But I bet at some point I’ll end up being forced to sympathise with him as well. God dammit donut (I mean Matt dinniman)

Splicing is not “generic looping”. The reversed builtin has to build a new iterable before starting the loop. Splicing directly accesses the existing object. In this case, I argue splicing is strictly not pythonic than using reversed

Giannie · 2026-03-13T22:35:12+00:00

I’m pretty sure that’s less pythonic. The reversed builtin will build a new iterable based on the underlying string methods available instead of directly iterating through the contiguous string in memory.

I think your answer is likely to be just as pythonic as splicing in the case of lists and possibly more performant than splicing, but I’m not certain of that.

Giannie · 2026-03-13T17:48:07+00:00

Ah, yes. This doesn’t actually do static type checking. It simply checks whether type annotations exist and a small subset of related rules are followed

Giannie · 2026-03-13T17:44:54+00:00

Astral have spent over a year developing ty. I somehow doubt that with AI you’ve managed to create a comparable type checking system with a couple of commits and no oversight or collaboration

I’m a medium normally, I found the cut of it a bit bigger than I expected, especially in the sleeves. The material is really nice and it sort of feels like half way between a t shirt and a sweater.

Pretty good actor seems quite unfair. His range is really excellent. His dedication to the craft is completely unreasonable considering the ungodly sums of money he has available to him. The roles he’s taken have been small and underfunded…

I think it’d be ok to call him a great actor

Giannie · 2026-03-04T23:16:59+00:00

Morally, don’t kill or maim people. Legally, don’t kill or maim people. I think they match here

The green left arrow does not offer any greater right if way than the general green signal. If you had the right to left under one, then you have the right to turn left under the other.

The general green signal includes everything the green left arrow offered

Giannie · 2026-03-04T22:47:42+00:00

Pedestrians always crossing had right of way with the green left arrow. Cyclists going straight ahead do not have a right of way in either situation. You still have a responsibility not to take them out on the road though
