Will CCC explode now? :-)

Post by Mike S. »

The next days and weeks will be hot :mrgreen: Will CCC survive this or perish in desparation and anarchy? Maybe I should quit for a while, at least for the rest of January. But I expect one 'number of postings per hour record' after the other. Smoking keyboards! :D

C U in February.

Hi Mike,

as long as members can express their views without resorting to personal abuse, it should be fine. :wink:
I must note that discussions have been very interesting and abuse free of late.

I am not going to say that Strelka did or did not cut and paste code from another program or if it does or does not pose moral issues. I just think that a little bit of data to look at is enough to let every individual come to their own conclusion. Well I am getting cold so I am going to go search for something to trow on the fire so I can stay warm.

The function that does not is good to get any conclusions, I also use it in danasah, 99% of the programs use any algorithm that is based on ideas of others, but that's not so bad.

What's the egtb? Why is permitted then use the code of other peoples? Fruit use this code.
