I wonder if there's a difference between various types of self employment where some are on net less stressful than others. In my cousin's case as a co-founder, there may still have been a lot of pressure from other team members, which is only marginally better than having a boss. Also, if there are effective strategies one can employ to limit issues that can have a negative impact in a self employed context, then further studies to elucidate such would be incredibly valuable.
In theory the hardware probably could do what you're describing if someone wanted to hack the FPGA internals themselves. I'd love to hear if you ever have any success getting things running better.
The one thing to keep in mind (my experience is with the E200 though the E310 hardware architecture seems pretty similar from what I can see) is that the sampling rate is somewhat CPU bound by the onboard CPU. In spite of having a GigE interface, your sample rate will be limited to somewhere on the order of 110 MB/s which will give you a combined (Rx and Tx) sample rate of under 15 mega samples per second. I have heard of some people try to overclock these to boost the sample rate a bit. If that is all you need I could definitely recommend it though.
There's plenty of non-binary schemes used in modern digital systems though. Modern NAND flash is one instance, for example QLC SSD drives store 16 distinct levels per storage cell (allowing each to encode the equivalent of 4-bits of data). Another example is 64-QAM, a modulation scheme used in a variety of places, including 802.11n Wi-Fi and Digital Terrestrial television (among others), which forms symbols out of two out of phase sinusoids, each of which can take up to 8 amplitude levels.
And even electronic computers haven't always been binary, one of the early Soviet computers was ternary, relying on 3 digits rather than the more familiar 2, to do all of its core computing functions.
I was wishing for something like this recently so I'm genuinely pleased to know this exists.
I remember an interview with one neurologist who stated humanity has for centuries compared the functioning of the brain to the most complex technology devised yet. First it was compared to mechanical devices, then pipes and steam, then electrical circuits, then electronics and now finally computers. But he pointed out, the brain works like none of these things so we have to be aware of the limitations of our models.
Now let's take a much more reasonable speed like 10% the speed of light. Assuming the 100 protons per cubic meter figure above, each square metre of ship now only needs to dissipate 2.27 mW of energy. 10% the speed of light is enough time to reach Alpha Centauri within a single lifetime (42 years). And fast enough to visit every part of the galaxy in less than a million years. We could even imagine generational ships travelling at 1% the speed of light (now the energy dissipation demands are 2.25 μW per square metre of ship surface). That's still under 10 million years to colonise the entire galaxy.
If intelligent life is abundant in the galaxy then I don't think the speed of spaceships at least offers a fundamentally insurmountable technical challenge for that life to spread everywhere.
First, the warm and fuzzy feeling you get by confirming your chosen world view doesn't take very much work. Just a couple minutes on Google.
Second, for many, the mere suggestion that there is a need to learn a new skill connected with research will likely be interpreted as an attack on their intelligence.
So the real question we have to be asking is how we can motivate people to even want to uncover truth even when it leads to discomfort. The answer is obvious for those who have already arrived there but not for those who haven't.
I used to be a huge Ruby fan but having exposure to Python where this isn't an issue, life is just easier.
