That last isn't defined explicitly. It's an emergent property from the constraint that the solution must be unique. Any blue circle (or any linear group of them) that is not in line-of-sight with a numbered circle would have no c

Yes. Any deduction that you could reach from that fact could also be reached from other constraints on the board. Here's an example illustration, from the top-left corner of a board: y B R x R _ _ _ _ If x is red, then y is

That's what the hint button is for. If you start adding any automated processing like that, then you're only a couple more processes away from the game just solving itself without you. The elegance of this implementation is that

This approach is effective, but is stateful and iterative. There's elegance and quite likely reduced computational load in a functional approach that can give the wave height value with only the inputs of the coordinates and time. Th

It's discontinuous if the value is undefined at the origin. That happens here because the denominator of (x + t) yields a division by zero. A nonzero slope would give a kink in the curve, but not a discontinuity. One approach to av

It's possible with a regex. Here's one spectacularly awful way: enumerate through all the permutations of 3 out of 4 character classes. Assume the classes are A, B, C, and D just to simplify the syntax here: (.*A.*B.*C.*)|

If you're accessing objects that deeply, something is breaking the Law of Demeter about locality of reference and looseness of coupling. It's a syntactic convenience, but it leads to questionable patterns. Do you really want to s

I understand the concerns, but the same "have you tried implementing" concern applies there too. This is premature optimization, until you do it both ways and profile it and see if the runtime difference matters. Cache locality

Why are we storing in an array at all? Why keep that last vestige of rectangular representation? How about storing the map directly in cubic coordinates? The storage structure would be a dictionary with a three-value tuple as the key. It

Why do we delete the largest arc? I couldn't understand the elegance of the spiral until seeing that that had been done. Deleting that largest arc breaks the self-similarity. Without it, the topmost scale becomes an S curve and does

Shareware involved two different ideas: the method of distribution, and the trial to paid purchase model. Shareware was genius in encouraging users to copy programs around to each other in the primitive days of computer connectivity. But t

The actual answer to your question is that the Atari 2600's fundamental limitation is sprites per scanline, not per screen. It can draw lots of objects by reusing sprites across many scanlines, but can't draw many objects that ne

Yup. Estimation inflation syndrome is a thing. One of my previous jobs suffered from that all the time, on database sizing. How much space does the client need for this trading app? DBA figures 1k transactions per day at 1kb/record

There's a disconnect in the show's treatment of parts of the characters' lives, which accounts for the divisive polarity of opinions on it. The show manages to be both pro-intellectual and anti-intellectual in different area

This is correct. I think I may have fat-fingered a downvote on you.

There's some no-true-Scotsman going on there. If one defines anywhere with more poverty than the US as not western, then by definition the US will have the most poverty of western societies.

The thing is, layout is content. Even right here on HN. One comment being a reply to another is indicated visually with a level of indentation. That's semantic meaning. A comment saying "I disagree" carries vastly differ

Here's my favorite, from the Atari 2600. The graphics chip has two "missile" objects that act like simple sprites that are only one bit wide. They are each enabled or disabled by writing 1 or 0 to a certain bit of a certain

It's competitive. The price is $879, for those who missed it deep in the article. There are many places where 45 days worth of rent at that price will get you worse environs than a train.

Regulatory capture. Interests concerned with protecting ISPs' monopolistic profits have more government influence than interests concerned with the good of the consumer.

Usenet is the closest thing we've got to that. Although it lacks any voting or ranking system to filter content. Whether that's a bug or feature is debatable.

Sorry but gotta jump in to set this straight. Amit programmed Solar Realms Elite. His brother Mehul did Barren Realms Elite. SRE came first, then later BRE was the more popular one thanks to the inter-BBS play.
