noise

Replaced motherboard; speakers; put in an additional fan; but this did not stop the static noise. This was done by inhouse tech. support from Sony. If i turn my speakers mute; the sound is still there! Can't hear it through headphones. I was told it is feedback noise! Now I'm suppose to send my $2,000.00 computer through the mail to get fixed? I'm terrified it'll come back in terrible condition during the travel time? Help?

Simplex noise vs Perlin noise

as seen on Stack Overflow - Search for 'Stack Overflow'
I would like to know why Perlin noise is still so popular today after Simplex came out. Simplex noise was made by Ken Perlin himself and it was suppose to take over his old algorithm which was slow for higher dimensions and with better quality (no visible artifacts). Simplex noise came out in 2001… >>> More
