I wonder if Google pays attention to outside research like this, or considers itself ahead of the outside world.

Wow. Can't disagree more. Compressed audio only sounds better on crappy speakers. Maybe they are common with phones.

Thanks for the info on ΔΣ converters. It connects several things I knew about. Now I need to study up on the area of computation that clover lives in.

I was never able to sleep on my back. I usually slept face-down with me head tilted a bit. I didn't know why. I now know I had sleep apnea my whole life. I started using a cpap about 15 years ago and I can now sleep any way I want.

Many years ago (1970s) I used very expensive but very accurate HP spectrum analyzer. It would take in a signal and present the spectrum on a screen. I studied the manual and found that it used a 1-bit(!) A/D. When averaging over man

I've read that the main reason the 8087 was produced was to standardize the floating point algorithms. Software in those days had notorious FP algorithm problems. I'll try to find a reference for that.

Mechanical pencils haven't been mentioned. They follow a similar history. The Sharp electronics company was founded to make pencils in 1915. Their Ever-Sharp pencil was a big success. When I did business with them a number of years a

Sure. But I assumed one goal was to offer low-latency access to a high-latency service. I.E. Act as a cache.

A question unrelated to your programming concepts: If you only query your source when a request comes in, doesn't the first requester get old data? This is a problem I have faced before.

Interesting. When cars first appeared the public hated them and the drivers. When a person was struck down the driver was usually convicted of murder.

I got excited because I thought that I might finally understand infinity. Unfortunately I am still not there as I am not there with quantum mechanics. I have read many books on both with equal non-success.

This is often called the NASA approach since they've hired multiple companies to provide the same component many times. Then they use the best one.

My wife bought a cal king purple a few months ago and we love it. I was skeptical because it looked like memory foam but it isn't at all. I was also worried it would sag when you leaned over an edge since there was no special side su
