Comment Re:You will pry my Sound Blaster (Score 1) 62

They did - I mentioned that they intercut code to do sound with other processing, so sound effects had somewhat "tinny" sounds because it could only "play" a few ms of sound at a time, then let the CPU do other things, then played more sound, etc. There was no threading or specialized sound hardware to do both simultaneously.

Back in the era of the original IBM PC and its clones (I had a Sanyo MBC-550, which had upgraded graphics from the IBM and could do *8* colors at once, at 640x200, instead of just the usual 4), the PC speaker had to be pulsed directly by the CPU to make any noise. Pulse it at 440hz and you have middle A, etc. While it was making noise, the CPU couldn't do anything else. To make music or sound effects you kind of had to split up whatever sound you wanted so the CPU had a chance to "do stuff". There was a magazine for the Sanyo at the time where someone had written some assembler code (that you could call from BASIC) to make the CPU make any pitch for a specific duration. I wrote a sequencer based on that code that would call the function with .128s "pulses", leaving time to monitor for key-presses so you could change the pitch. Then I got an Amiga and everything changed!

Comment Multiple layers? (Score 0) 89

Are they already designed using multiple layers? I'm no photovoltaics expert, but with 20% efficiency per layer couldn't they combine 5 layers to achieve "100% efficiency" per window? Seems like with enough windows a building could theoretically get all of its power from solar - at least on sunny days.

Comment Wait for HDR (Score 4, Interesting) 330

Don't buy one now. High-dynamic-range television is coming, and a consortium of TV suppliers was announced at COMDEX recently. They will work together on coming up with a single standard for HDR. Netflix has also promised to deliver HDR content by year's end. It would be silly to buy a 4K panel that can only process rec-709 now when HDR is right around the corner.

We lived on a mountain in Virginia. When I was in second grade the neighbor kid and I would go hiking up the mountain, following streams and looking for waterfalls. I remember one waterfall we found, probably 70 feet high. We found a way to climb up the sides, got to the top, and found these big boulders. We'd roll the boulders off the top of the fall and listen to them crack on the rocks far below. We'd be out doing that all day long.
Later we moved to a lake and I would just disappear for the day exploring the surrounding are. This was life in the country.

Comment Gotten out of hand (Score 1) 78

I recently got two take-down requests for two videos I put up on YouTube. They were both trade-show demo reel videos that I helped produce showing post-produced results in television shows and movies from software I wrote. These videos were 20 years old, but I thought it would be good to preserve them.

Paramount wanted one taken down for a 2-second clip from a Paramount movie. Someone else wanted the other taken down because I guess they owned the copyright on the music we had bought to accompany the video.

One could argue that putting these videos up was entirely fair use but I didn't argue at all and just yanked them. Not worth it.
