Re: Task force TalkChess access

I still don't get it. In a freshly created forum (such as the one at http://212.114.109.12/new ) voting in the polls does work, with the same browser. Apparently the 'update' parameter does get a value in the POST request there. But the HTML for the form looks the same; there isn't any extra "&updat...

Re: Task force TalkChess access

This is apparently a standard phpBB option: initially you are not shown any results, but there is a link "View results" under the Submit-vote button, which would display the page again with an extra view=viewpoll argument to the URL. Which forces showing of the results. Perhaps this can be disabled ...

Re: On the ownership of TakChess

The hosting is not the problem. The domain name is. Hosting in a different domain is already accomplished.

Re: Task force TalkChess access

Ah, some progress! I tried to print the body of the POST request (var_export($_POST)) as debug output on the page, but since the POST request itself doesn't result in anything being shown when the PHP voting code is not exectuted, this did not work. Then I found an alternative method to detect if th...

Re: Distinguish rook and bishop move efficiently

BIG DISCOVERY EMANUELS ROOK / BISHOP DETECTION STRATEGY bool is_rook_move_emanuel(int from, int to) { return 0x1010101010101fe & 1ULL << (from ^ to); } Over twice as fast as the previously suggested methods!! Emanuel does it again!! That is a LOAD (of the constant 1ull), a LOAD of the 'magic number...

Re: Task force TalkChess access

Well, perhaps someone else is still willing to help debugging this? I have figured out now (in FireFox, opening the 'developer panel' with F12, and selecting 'network', so that it shows me what the browser sends to the server), that pressing the 'Submit vote' button in the poll at http://212.114.109...

Re: On the ownership of TakChess

From - That would sound reasonable if Ed wasn't firmly in Quentin's camp... And - No, I was referring to an e-mail Ed sent me when we were discussing how to fix the forum. Ed said my plan to test on another server, directing all traffic there, could not be attempted without Quentin's permission, be...

Re: On the ownership of TakChess

Well, nothing was agreed by me, as there wasn't anything to agree on yet. It is not clear to me: does the database and the experimental newsite also contain the user data (email, password ...)? Because in that case it would be a pretty big violation, at least under EU law: user data must not be mad...

Re: Task force TalkChess access

Well, Ed's fake news is doing a lot of damage. In fact Quentin has no objection at all against the TalkChess poll function getting fixed. And it makes absolutely no sense that he should. BTW, looking at the code I noticed there is a variable $update, which is used in conjuction with $s_can_vote to d...

Re: On the ownership of TakChess

Well, nothing was agreed by me, as there wasn't anything to agree on yet. YOU wrote to Quentin: In principle we will try to solve the problem so everything we remain the same Assuming you meant "will" where you wrote "we", I took this to refer to a permanent move, not to running experiments on a moc...
