@foone @whitequark usb is 3.3v fake differential signaling I don't see the problem? You don't need level shifters

@mwk @nazokiyoubinbou the catgirl knows what its labor is worth, because it knows what its labor isn't.It knows what its labor isn't worth because it's been underpaid in the past. By subtracting what its labor isn't worth from what it needs to survive, it obtains a difference, or deviation.

@gabrielesvelto If those are just connected by hub, it's not too interesting.But if they actually have like 10+ XHCI's... Where do I send the check?

Looking to replace the default Android calculator app with something F/OSS that can do base conversions, display bits in a value, etc. Any suggestions?

@ignaloidas I use it on desktop, was not aware they had a mobile version.

@ignaloidas Says "not compatible with your phone", no obvious reason why.

Yes, this is exactly what it looks like. RJ45 probe fixture -> ThunderScope -> ngscopeclient -> eye measurements and protocol decodes -> Wireshark.At >80% of real time, and we're closing in on the last few bottlenecks rapidly.

Can somebody explain why MLC/TLC/QLC flash is apparently slower to write than SLC?it seems to me that if you're PAM4/PAM8/PAM16-ing the same amount of data across less bitcells you should get *higher* write speed. Why is MLC not double the write throughput of SLC?

@jpm I'm not talking about erasing, I'm talking about writing. My understanding is a lot of modern SSDs have a fairly small write buffer of fast SLC bitcells and when it fills up write speeds drop as subsequent writes commit directly to the TLC/QLC array.What I don't understand is why it's not the other way around. I thought SLC was something you used when you wanted the highest longevity and reliability *at the expense of* speed and density.

@jpm also why would multi level bitcells take longer to erase? You're erasing the entire page regardless of what was there.

@jpm yeah but don't most FTLs implement log structuring where you write until the block fills up to avoid write amplification?

I would expect reads to have similar results with caveats: the higher BER will mean more frequent error correction operations, so depending on how slow the FEC is you might not have e.g. MLC reading at twice the speed of SLC.But I would still expect a net performance *and* density gain at the expense of BER and endurance.

Calibrating and testing my shiny new PCIe card ThunderScope prototype.It's soooo smooth. I'll never get tired of having many-megapoint waveforms refreshing at a steady 60 FPS.

Random thought of the day: if someone wanted an EV *fast* charger at/near home, how much would the power company charge for all of the necessary infrastructure?Like, putting a megawatt supercharger on a random residential block that's currently only wired with like 7200V single phase.I feel like you'd probably have to run a new medium voltage line all the way out to the nearest substation. Judging by what I was quoted to run fiber a shorter distance you're talking >$100K just for the cable plant, plus whatever additional transformers, reclosers, etc. would be required for the project.

Steps to greatly advance the state of the art in any relatively obscure field:1) Find a bunch of autistic nerds whose special interests broadly overlap with said field2) Put them in contact and let them share ideas or, better yet, lab space3) Buy them whatever they ask for4) Wait and see what they come up with. Excitement guaranteed, you just have no idea exactly what kind.

@acsawdey @niconiconi we do have https://ultraethernet.org/ though
