Re: A fabulous thing about Winboard

On the original point of "Who the hell can read that PGN", or what program can, I can tell you mine cant. I don't even know if it's in the PGN spec as i never read the PGN spec. My code which is now in 4 of my apps, OpeningTree on iOS and Android and Pulsar Chess on iOS and Android, was written for ...

I've gotten lucky with a few of my Uber eats drivers like the one today that i rate marriageable :) Still it doesn't cost 24.95 for delivery but then again most of them are not keepers.

Re: A fabulous thing about Winboard

In C++ all you have to do is: try { something_that_might_crash(); } catch (...) { // friendly, diagnostic error message goes here. You can get a lot more clever if you know what the likely exceptions are. } There are two schools of thoughts on try catches and to be honest i've joined the latter sch...

Re: A fabulous thing about Winboard

Lots of programs would just crash on bad input. That's lazy. Having written PGN parsing code the process i went through was something like i have 2-3 weeks to write the PGN code or some time and tried to test it on common file types i expect to be loaded. This included PGN from Chessbase, Internet ...

Re: A fabulous thing about Winboard

Sometimes old code bases get out dated or hard to maintain. Winboard is lucky that from what i know of the authors, it's probably well written, and it's been maintained both past and present. The more time an author has over the years to update certain types of code, for example the PGN parsing, eng...

Pulsar Chess on Android 4.2 released

Fixes a major bug in Pulsar making moves introduced about 3 weeks ago that could cause it to put an extra rook on the board. This had to do with how castle rights were set. If this was a work outfit there would be a retrospective on this by now :) This marks the third bug in castling i've fixed sinc...

Re: Komodo 13 released

All Komodo are much below Stockfish right now. Around 60 elo at very least in TCEC condition. That's what i thought. So is komodo trying to hold down the elo of its standard engine just to give time for mcts to catch up with it? Komodo can be nice for analysis. I tend to use stockfish as that is de...

Re: Authors of chess engines getting crushed by their creations

I"ve always had a firm respect for the break throughs on the computer science level in chess since I first became familiar with the scene in late 1998 on ICC's channel 64 for chess programmers. Back then Bob was online running Crafty(C), Diepeveen was running Diep, Bruce Moreland was running Feret w...

Re: Authors of chess engines getting crushed by their creations

Creation is too strong a word. The creative person is the one who first did something. The later ones follow a recipe. Bob Hyatt, the Crafty author, was a pioneer of parallel computing. Myself when i started Pulsar didn't have much claim to fame i was not following a recipes. But I wanted to do som...

Re: Authors of chess engines getting crushed by their creations

Not sure this is "news". In the early 80's, I might win one out of 100 games against Cray Blitz, yet our ratings were pretty equal in terms of USCF. 5 years later, that was zero out of 100. Been that way all the way through current Crafty. It is really easy to develop an engine that beats you trivi...
