Re: Java security problem

For a statically compiled application and for a buffer to overflow, there must be a reason: division by zero, missing garbage colletion or interpretation of unchecked input of network data or GUI entered data. The programmer need not be a security expert to avoid such, but he just needs discipline ...

Re: Java security problem

or b) convincing the programmer to avoid JRE. Either way closes the vector of JRE-related security issues. (Provided one does not have to use third programs depending on JRE.)

You are missing one crucial point: Sure, not using JRE closes the vector of JRE-related security issues. But it also ...

Re: Focus

By the way, right around New Year's I discovered Habit RPG. It was pretty good at forcing me to do things that I wanted to do... although staying logged on to my computer record stuff on it was a bit of a drag, and the website kept going down. You should try it. Habitrpg.com

Re: One Space and Two Space Jump

I have been reading Opening Theory Made Easy for a few days, and it uses one space and two space jumps to run away/attack a lot. Since both jumps can be cut , especially the two space jump, why would it be a good way of fleeing or attacking ? In what sort of a position would these jumps be safe ...

Re: Cats and Go

I think cats always want to take part in the activities you're interested in. If you're sitting in front of the computer a lot, they're going to come and sit on your keyboard or mousepad. If you're reading comic books, they are going to sit in the middle of the comic books. And if you happen to play ...

Re: Go Programs and counting...

It depends on the context. Sometimes you want the computer to determine the score without human interaction.

But in the standard case, I agree, the most practical solution is to let the players remove the dead stones manually, and then solve the much simpler sub-problem of flood-filling the ...

Re: Go Programs and counting...

No, it does not apply to the technical definition of stone/area scoring. It applies to the practical problem of determining who won the game at the end.

Of course you can always simplify a problem by just changing the problem statement in a way that is convenient, but in doing so, you didn't ...

Re: Go Programs and counting...

Only life-and-death dependent scoring is hard. Area scoring, stone scoring etc. are O(n), i.e., as trivial as flood-filling.

Nonsense.

Your seemingly trivial flood-filling can not remove dead stones, and it also doesn't handle seki.

Read the paper I referenced.
You're of course free to disagree ...

Re: Go Programs and counting...

Is counting a difficult problem for computer programs?
Actually, scoring a finished position is PSPACE-hard

So in general, yes, counting is a very difficult problem for computer programs, even for finished positions. But in practice, heuristics can help. Especially for bots that is not a ...

Re: No 2 Games Alike?

I'm also pretty sure no two games played on internet are exactly alike (except on purpose). The probability of that happening is still low enough ;)

Theoretically (with access to the database of a go server), it shouldn't be that hard to check :P
