tridentboy··on If the moon were only 1 pixel: A tediously accurate solar system model (2014)
First set gamma as being 1/sqrt(1-v^2/c^2), with "c" being the speed of light. The factor for time dilation and distance contraction in special relativity is gamma and 1/gamma respectively.

That means that when you get to speeds equal to c, your time runs infinitely slower and the distances are infinitely shorter. So if your clock is infinitely slower, so every travel at "c" speeds means that no time passes for you. And if your distances are infinitely shorter, all travels at "c" speeds cover any distance as immediate. So you could reach every point of the universe as if it was immediately closer and in no time at all.

So in the frame of reference of the photon, the moment it is created it has already reached its destination, be it wherever it is on the universe.

Of course we can never reach "c" as beings with mass, but we can get closer to that. So for example if you get to 99.99999999999999% of the speed of light, you could travel a distance of 54,794,520 ly and only one year would pass to you, while 54,794,520 years would pass on earth.

tridentboy··on Bay 12 Games has made $7M from the Steam release of Dwarf Fortress
The thing is that this is the first time they got this kind of money. And it was unexpected, since Dwarf Fortress sold their 8 month objective by the second week. So they weren't in a position of knowing who and how to call that someone.
tridentboy··on Euler’s 243-Year-Old ‘Impossible’ Puzzle Gets a Quantum Solution
You've missed the fact that there are two attributes, rank and regiment. So it's something like this for a 3x3:

1A - 2B - 3C

2C - 3A - 1B

3B - 1C - 2A

tridentboy··on The Math of Card Shuffling (2018)
Well, it seems that his point still stands. Overhand shuffle is terrible for actually shuffling a deck of cards.
tridentboy··on Show HN: SHA-256 Animation
I'm sorry, could you please elaborate? I was always under the assumption that hash functions have to be deterministic, and thus, that "every input has a unique output" was a correct statement.

AFAIK the contrary is invalid, so that "not every output is the result of one and only one input".

tridentboy··on Tell HN: C Experts Panel – Ask us anything about C
Know it's not exactly related to what you do. But do you have some recommendations of books/online classes to learn C?
tridentboy··on Why Are Some Societies More Entrepreneurial than Others?
There is a big difference in the intervention made by US in east asian countries, and the interventions made by superpowers in other countries.

I'm not saying that South Korea and Japan didn't make good use of this intervention, but while the intervention in those countries was more akin to a financing/investment, which was in line with US' Marshall Plan during the Cold War.

In other countries such as those from Africa/South America, it was direct exploration of people and resources without really giving something back.

tridentboy··on Using Python to Get Free Chicken Sandwiches
I don't think "these days" really apply to this situation. People have always tried to take advantage of flaws in any system.
tridentboy··on Nearly Half of Game Developers Want to Unionize
Statistically speaking 4000 is a good enough number. I mean, election polls in the US usually use less than that for a population of 300 million and they're usually close to the real number.
