Particularly odd since the Swedish calendar has had a lot of leap-day shenanigans, including a one-time Feb 30th. https://en.wikipedia.org/wiki/List_of_non-standard_dates#Feb...

Payroll software at work had a one-off planned maintenance day today, presumably to avoid worrying about any bugs.

I see. A tricky design constraint; if you _indicate_ it's from the second-chance pool it might not get a fair shake but if you don't it'll look old and unpopular and might not get a fair shake. Maybe for something like that

It's not about credit; this thread shows that I submitted it. It's about saying I did something at a time when I was asleep.

I posted this more than 6 hours ago, no matter what the timestamp says. This has happened to me before [0] and I still wish the time weren't rewritten. https://news.ycombinator.com/item?id=29529099

I do the NYT crossword every day (current streak = 1079), and I loved to solve a rubik's cube as a kid. This game is absolutely incredible. In about 10 minutes I've done a bunch of 3x3s and a 4x4 to see how it works with black sq

Well since there are no margins you have to make up for it in no volume.

If you're talking about renormalization, let me say that as a working physicist, this critique is misguided. In a Wilsonian picture there are no infinities. Lattice field theory, for example, has none. After my first two QFT classes

Some states used to have at-large seats in addition to districts. But the court basically killed that in the 60s. There might be a clever legislative solution that would still be in the bounds of the 'one person, one vote' requi

You might find vim-anywhere what you need. Roughly speaking, in almost any text-entry field you can hit a hotkey, get a temporary macvim buffer, and when you wq the contents are pasted where you came from. https://github.com&#x2

Stating the conserved quantity (baryon number = 1) makes it correct in a precise, meaningful way, even if it's not the whole story. Most people don't have the background to understand the subtleties of interacting quantum field t

The number of valence quarks is 3. Or, put in a more rigorous way, the baryon number of a proton is 1.

I explained roughly speaking why this is called gravitational without actually involving an experimental use of background gravity or gravitons in this comment some months ago: https://news.ycombinator.com/item?id=35444056

Many. Just to give an example, the very first Nobel in physics was awarded to Röntgen, who discovered 'A new kind of Ray' (which only later named x-rays and were shown to be photons with a different wavelength). He noticed a det

Just appending 0s to change scale is true in any base. If you'd grown up in base 12 you'd write that 100 one-hundred-forty-fourths is one and that there's nothing particularly simple about A As (84 in your natural numerals),

'Every' modifies the meaning. It's just as sensible and correct to say 'every second number is even' and 'every second number is odd'.

I meant young as maxnoe suggests but you’re right obviously, a better less ambiguous thing to say is that they are from a time/place when/where no other stars have yet had the opportunity to die.

In astronomy 'metal' is shorthand for 'all elements except hydrogen and helium' [0]. This is a convenient shorthand because big bang nucleosynthesis [1] produces only minuscule amounts of lithium and even less heavier e

I think you're making an error---according to GR the singularities in black hole cores are in time, not locations in space, as confusing as that is, and as much as colloquial language suggests it. Every geodesic that crosses the horizo

Time reversal symmetry is probably the most subtle of the discrete symmetries. Suppose you have a video that follows the moon and the Earth from some distance but that no other celestial bodies are visible, for simplicity. If you reversed t

General relativity doesn't say anything useful about electromagnetism or baryonic matter either; I'm not sure you can lay an absence of an explanation of dark matter at its feet. For dark energy of course is much harder to say...

If you want to faithfully capture real-time quantum effects your program’s memory and runtime scales exponentially with the number of particles. A quantum simulation scales polynomially.

I of course agree with most of what you say. The thing that impresses me about this whole ruliad business is that it seems to operationalize computational version Tegmark's mathematical universe hypothesis: all sets of mathematical ax
