This reads like someone proficient in signal processing is explaining the core concepts to another person who is already proficient in signal processing.
Exactly right! As somebody who’s spent a great deal of time with the discrete Fourier transform, I thought, “this article reads like it was written specifically for me.” I/Q modulation is new to me though.
The data and PD communication are both working (that was the majority challenge on the EE side, shown in his video). So it would depend on the capability of his solution to let the phone work in host mode, thus being able to provide power to the adapter.
Though I'm also not sure how the MFi situation is with those generations of iPhones, and what restrictions Apple has built in to the OS. I haven't worked with MFi for a while, and I don't know for sure if MFi chips are even required anymore for that generation of lightning devices, or whether the author has incorporated one.
EDIT: I just saw this on his website:
> Any other accessory that requires power from the phone is not compatible.
So no, USB-C to headphone adapters won't work, they need power.
The fact that they do product recalls should bias you in favour of them. Other brands simply don't do them at all, and the reason is not because nothing ever goes wrong with them.
There absolutely is; formally speaking, statements can be categorised into normative, saying how things should be, and positive, saying how things are. A politically neutral AI would avoid making any explicit or implicit normative statements.
This presumes that the AI has access to objective reality. Instead, the AI has access to subjective reports filed by fallible humans, about the state of the world. Even if we could concede that an AI might observe the world on its own terms, the language it might use to describe the world as it perceives it would be subjectively defined by humans.
AI simply not openly and proudly declaring itself MechaHitler while spreading White Supremacist lies and Racist ideology would be one small step in the right direction.
Seriously. Is _that_ what it means to have a conservative government? Because I thought it meant they would keep their hands off the market. This is straight from the PDF though:
"Led by the Department of Commerce (DOC) through the National Institute of Standards and Technology (NIST), revise the NIST AI Risk Management Framework to eliminate references to misinformation, Diversity, Equity, and Inclusion, and climate change."
Isn't that why we have government? We have judges to make the final say on right and wrong and what the punishments are for transgressions, legislatures to make laws and allocate money based on the needs of the constituents, and an executive function to carry out the will of the stakeholders.
Clearly there are terrible governments but if it's not government tackling these issues then there will be limited control by the people and it will simply be those with the most money define the landscape.
Does the individual consumer have any agency in which AI services he chooses to consume?
As I understood the original premises of the US gov, it was to be constitutionally limited in scope. Now I know that ship has sailed a long time ago, but I don't think it follows that we have a gov. to centrally plan AI content as right or wrong.
AVB and TSN are relatively new addition to Ethernet, and specifically designed for realtime AV use. Traditional Ethernet is not really intended for tight real-time use.
There is audio distribution real-time and nuclear reactor (or avionics, medical, etc) real-time. I assume the people doing (or certifying) the latter will want better guarantees.
The usual terminology is hard, firm and soft realtime. In hard realtime, missing a deadline is a total failure and to be avoided at all cost, i.e. your reactor melts down, you car runs over someone, stuff like that. Firm realtime means that a missed deadline will not be a total catastrophic failure but it will make the result useless. E.g. when your printer control system mistimes the "fire ink now" in the printer, and the ink lands not on the page but somewhere else. Soft realtime means that your result will gradually degrade with missed deadlines, but not be totally useless.
Audio is usually soft realtime, sometimes, e.g. when doing studio recordings, firm realtime.
It should be noted these distinctions don't correlate with timing; you can have a hard realtime system that needs some network packets at 50ms±10ms intervals, and a soft realtime system that needs packets at 500µs±5µs.
Some audio setups are run quite "close to the metal", both because it needs less buffering, but also the lower human threshold for noticing latency seems to be around 10ms. And having audio not get out of phase with multiple sources/sinks gets added on top of that.
Correct. If you imagine having a dam overflow, the release valves are a hard realtime system. If the dam overflows for more than a few minutes, damage will occur, so the release valves need to be opened within, say, overflow plus 5mins. A generous deadline for any computer, but still a deadline that needs to be kept at all cost.
I don't understand how people can propose these ridiculous schemes with a straight face. I suspect it is because "climate change" is a good source of grant money right now, so you have to get creative to come up with a new approach.
On the other hand, if you're in climate science, what are you supposed to do? The science is pretty clear right now, what we lack is political action.
Yet when climate scientists stop using the carefully-weighed language of academia to demand actual, effective and efficient action now, they get scolded as activists, emotional, non-objective, etc...
This is just to say I can understand that people just want to contribute within their realm of possibilities.
