While the comments here are almost universally negative, this actually isn't that bad of an idea. Not just because of the freedom aspect, though I'm generally fairly principled about that--I'm more concerned about security an

Pedantic aside: I guess you mean non-associative multiplication? That is, ax(bxc) versus (axb)xc. Since rounding happens at different times, they can give different results. Floating point multiplication is indeed non-commutative as well, b

Cool game! A few notes: I think your choice of license may be incompatible with the GitHub terms of service--there's an implied right to fork by using GitHub, but your license states no derivatives are allowed. IANAL, but something to

Weird. I got to 80k in Firefox, and stopped because it was pretty slow and not getting faster--not really challenging at all. I tried again in Chrome and its a lot faster, and does get faster throughout the game as well. More fun and challe

With Python's evaluation/assignment order, both parts of a complex assignment happen at once--which is the source of the weird behavior in the article (A[0] is assigned to before the subscript of A[A[0] - 1] is evaluated).

Tiny bug report: after clicking on the levels and going back to level 0, all of the buttons on the sides disappear.

The first--the latter isn't in order (expr3 is "evaluated" before expr2, which in this case means assignment).

Shouldn't that 16 be a 256? 4 squares with 4 orientations each = 4^4 = 256. But yeah, definitely pretty doable with a brute-force memoized search. I imagine a lot of state space could be pruned by doing some analysis of when squares ca

Seems like a lot of this speculation could be replaced by a few benchmarks to see whether the phone actually got slower... but I guess that would take more time than looking at a Google trends graph.

Looks fairly similar to PPSPP: https://datatracker.ietf.org/doc/draft-ietf-ppsp-peer-protoc... Both look pretty cool, I'd like to see some more traction in this area.

As a general rule, when anybody refers to a problem being NP-hard or whatever, they're talking about a generalized version of the problem, with at least one "size" variable--the time complexity has to be polynomial/expon

OK, so it's fixed now. Tested in Firefox, Chrome, and Safari. As soon as rawgit refreshes its copy, the new version will be live.

Ah, yes, I had forgotten that I didn't test in anything other than Firefox. I'm very much not a web developer--working with JS is really quite a pain, and I had to use as much ES6 magic as possible to make it tolerable. Looking no

Huh, I just made a pretty similar game a couple weeks ago. Mine is different in that it it's way less polished, starts with a randomly-initialized grid, and rows/columns that are all the same color disappear (so the goal is to mak

I guess the filter should only include titles with a colon after the "Show HN". Right now there's the story from yesterday: "Show HN vs. TechCrunch vs. Product Hunt: what's most effective to launch a product".

You can do arbitrary computations, but you only get the encrypted result. So you can't actually tell whether x == y unless you have the key.

cd is a shell built-in, not an external command. It has to be, since it changes the directory of the shell process, which can't be done by a child process. So shells do have to implement this specially.

It's pretty weird. My mom just died of cancer a little more than a week ago. I thought it would be a bad idea to read this article, as it would just pointlessly make me (more) depressed. Yet, at the end, I really just felt numb to any
