I recognize this problem, it was one of the first programming tasks we had back in uni (not to fix code, but to make that star triangle/"christmas tree" from scratch in Java). Very difficult to believe people with degrees can't solve it... It is a classic interview question. This is becau...

Are you using Apache? Have you tried adding more child processes?

You've made me curious, can we see the code?

A* is an extension of Dijkstra's algorithm. Basically, Dijkstra is the same as A* except it doesn't have the heuristic part.

A* is of course weird here because you don't need the heuristic part for anything in this case, but this could totally be done by modifying Dijkstra's algorithm. You'd iterate through the neighbouring nodes while keeping track of the step count so you can stop searching at max steps. After running t...

Been playing 7 Days to Die, too. A bit rough around the edges but still a lot of fun. Pretty hyped for alpha 7.

Why not update the gold when the player buys stuff? Your example doesn't really require polling for anything. I already did this. I even put the update query on top of everything, but for some reason in PHP it just can't :? (although in some part I found it working without I even know why lol) Of c...

At the end, $gap is a string, not an array. That's why you're getting one letter at a time.

Check your blocking function, that's where you're overwriting $gap.
