Yes, you are correct, vacuum tube amps have higher levels of distortion (and noise in most cases) compared to solid state amps. For vacuum tube amps the characteristic curve of distortion is a quadratic function called the second harmonic (frequency double the original sound and an overtone factor produced by most musical instruments - eg. a stradivarius - that gives depth and richness to sound). Solid state amps on the other hand produce tertiary and quintic harmonics that are not as pleasing to hear (which is why they try to reduce distortion for solid state amps to zero).
Slightly dated but eye opening article. Researchers estimate that by age 23 nearly one in three Americans will have been arrested. The number of Americans with criminal records today is larger than the entire U.S. population in 1900.
Living in the bay area these numbers were eye opening to me. Maybe YC isn't the right place for this discussion, but as a tech worker I'm wondering how we as a community can bring about any change to help disenfranchised youth.
As someone who works in the semiconductor industry, one of the most exciting things happening right now is the development and emergence of persistent/storage class memory (PCM/RRAM/3DXP/NVDIMMs). The implications of a persistent alternative to DRAM is immense and besides fundamentally changing compute/memory/networking/storage architectures it will also change programming models and SW stacks as we know them today. This is a topic I feel doesn't get enough visibility here, especially given that support for such technologies has already started getting baked in to Linux and Windows.
>>There’s also a wide body of research that’s found that decreasing latency has a roughly linear effect on revenue over a pretty wide range of latencies and businesses.
