And my job here, as well as in Siberia, have nothing to do with computer chess... I try to watch what happens in the computer chess world, but now too busy to write a new chess program. Maybe if I'll have some time, I'll finish my own tablebase generator - prototype works well, but needs some polishing (also, it's written in C++, and I heavy use some C++ features - e.g. templates). Because now RAM is much cheaper than it was when SJE wrote his generators, I try to use RAM instead of disk, so program runs faster than SJE's, and resulting files are much smaller than SJE's (there is compatibility mode). Also I want to experiment with compression routines written by my friend - he estimates that SJE's files are compressed 5-7 times, depending on the "chunk" size. Of course, decompression take some time, but (1) processors becomes faster much faster than disk I/O becomes faster, and (2) if program keeps cache of blocks that were read from disk, than that cache can be 5-7 times larger, so there will be much less I/O, and I hope that resulting access time will be only slightly longer. If I'll finish it :-(, I'll make sources public. Eugene
