Hi! This is my blog. It's for work, but I just write about whatever happens to interest me.

Hi. This is my company blog which I use to write about pretty much what ever happens to interest me.

Well, upon a closer look, one notices that the chessboard coloring is not necessary for the problem statement. It's kind of a hint actually as you could equally well just consider a blank 8x8 board and realize that this coloring arugment works. I just feel the problem is unreasonably difficult that way.

The coloring is kind of additional structure that is applied on the object you are working with. And I think this idea of "applying structure" is a very generic. You can solve similar combinatorial arrangement problems that way, but it goes beyond that.

I think that a nice, classic (and significantly more advanced) example is showing that plane and punctured plane (a plane with one missing point) are topologically different. The fundamental (homotopy) groups of these spaces are different, and hence the spaces cannot be continuously deformed to each other.

Somehow the spirit is the same, I feel. In this topology proof it's not a grid you are working with, but a topological space. And the structure you apply is not a coloring, but something quite abstract (a homotopy group). The idea in both cases is similar, though: You apply structure and this structure reveals something that's not easy to see directly.

The magic part is figuring out the structure that produces the data you need.

Hey HN, I run this newsletter on my site. Hope you like this week's post!

This is pretty cool, actually

Hi HN,

I'm Matias. I run a small business (ByteSauna) with a blog on the site. I try my best to serve well thought out content. Here's this weeks post.

Hope you enjoy it!

This is such a great site.

I wonder what the author would have suggested as an alternative at the time.

I'm a simple man: I see Dracula mentioned, I upvote.

I wrote essentially the same post yesterday. The interest in crypto is directly proportional to the BTC/USD rate. I don't see real innovation compared to 2016 when very few people talked about this stuff. The single thing that has changed is the price.

Isn't it funny that even though we are more productive than ever, at least in terms of GDP, we just seem to be getting busier.

Either this question would have to phrased in a precise mathematical form, or its hopelessly in the realm of metaphysics, where you can't get anywhere beyond speculation. Without precise formulation, it's impossible to be sure that we are even talking about the same thing.

It's not unheard of that a seemingly metaphysical question can be made testable with some ingenuity. Local realism is a great example: Local realism used to be subject to metaphysical debate, but since the 60's the Bell inequalities demonstrate a contradiction between practically testable predictions of the quantum theory and local realism. These days empirically measured Bell inequality violations are standard stuff that appear in physics journals (see e.g. [1]).

Unless we get something we can measure, the simulation theory has no better basis than the existence of an invisible pink unicorn whose job is to produce the quantum effects by disturbing our lab equipment.

Shameless plug: I recently built this.

It is SIMPLE for sure, essentially just an app for syncing files in real time between a bunch of users. If this could work for you, great! If not, I'd be glad to hear your feedback.

I think this is really difficult thing to explain to someone with zero background in technology. I did my best with this post, let me know if you have improvement suggestions or other comments. :)

I'll definitely consider making one! For now I'll keep on fixing some issues here and there :)

Hey thanks :)

Thanks! Mine is 144 ;D

Yeah, people are divided over this. Some people (me example) like this random element. Some don't.

This is a format I thought about a long time ago. No idea if it makes any sense, but decided to give it a shot and put it out there anyway. Making it was also a good few hour exercise.

Maybe there would be room for something like this these days when you are overwhelmed by information all the time.

I wrote a blog post about this: http://www.appsketch.xyz/p/3
