Sipeed teased a similar hack using some (undisclosed) USB-wifi chip, though I don't take them seriously as none can get their hands on the chips they tend to use.
Many cheap USB 3 Wifi 5/6 dongles out there, based on RTL8852BU and such. Just one QFN IC and XO. Their "firmware" seems to be a binary blob loaded over USB. I'm skeptical that these "testmodes" can be figured out with just bruteforcing, wonder if they load custom firmware for compliance testing or just leave those routines hanging around in release firmware too.
Closed binaries aren't much of a deterrent these days, we might see more such "discoveries" for a lot of devices.
On a technical note, not much I can find about the signal quality. Phase noise, images, DC Offset, etc. Have to get my hands on one, ESP32-S31 seems promising.
Liberals and progressives don't agree on most things related to (free) trade, but agree on not "bullying" allies for no reason and little profit.
As I mostly deal with single channel applications, I get to use double superhet and avoid runtime calibration. Not an option here, Zero-IF has too much in the Pros column for multichannel.
I have very little experience with MIMO / phased-arrays, this application likely doesn't need ultra high SFDR.
Neat way to reduce cost and pin-count? But I think the typical FPGA clock tree has poor jitter performance. Not using the internal PLL(s) might help with spurs but the clock buffers are unavoidable.
The documentation mentions it's likely further degraded by noise from switching regulators. Oh the joys of hunting RF noise sources.
Right now you have all the cons anyway, with none of the pros. A stitched-up database that has no laws attached to prevent its misuse. Just like with gun control, law enforcement could've made their job easier decades ago.
My city in South India could be an outlier but I see green EV number plates everywhere. Would love to see a state-wise breakdown for sale share.
The cheaper variants now have enough range to relieve (urban) range anxiety, wasn't the case a year or two ago. My own model that's 4 years old, the new variant now has 2.5x range, faster charging and much better features. All that for the same price, and without any of the subsidies that used to exist.
These things take time, this is a low-margin business that isn't drowning in VC money.
Even if the battery craps out after 5 years (extremely unlikely), it's a wash. That's before considering the fuel savings. Battery degradation is a bit of a meme, we aren't even 10 years into mass adoption of EVs for this to be a common experience.
Payment processor being down is payment processor being down.
Using a different, smaller cloud provider doesn't improve reliability (likely makes it worse) if the architecture itself wrong.
It's outright banned (commercial) in most of EU. In most countries it was left unregulated for a long time but most of them are choosing to ban all commercial forms of it. Besides US, most major countries have banned it.
Now many people do ignore these laws and most governments do little to enforce them unless they make the news for some reason. Banning commercial forms of it just ensures abuse and issues go unreported. It's the paternalistic part of feminism that's been leading the charge for modern bans, with both liberal and conservative roots.
I would say many asian parents care very little about the partner, as long as they get their grandkids. A mix of that and "what would society think".
Ofc the bigger perception issue here is many services going out at the same time, but why would (most) providers care if their annual downtime does or doesn't coincide with others? Their overall reliability is no better or worse had only their service gone down.
All of this can change ofc if this becomes a regular thing, the absolute hours of downtime does matter.
