There are entire subway systems built with tire-on-concrete where the trains ride precisely the same routes down to the millimeter. Montreal’s is a famous one. These systems are not as efficient as rail, but they are quieter and gentler than the typical subway.
Do you have any opinions on the use of frequency-domain/harmonics-based SPICE for high-frequency (relative to the transition frequency of the power and their pre-amp devices involved) fixed-frequency converters, particularly the resonant kinds?
At some point the gate signals become digital pre-distortion for the pre-amps ("gate drivers") and come out of a wave table like synthesizer, and sure, system-level behavior still matters...
For me the issue would be that they mandate the user traffic to be vlan tagged but their modem only exports 1000BASE-T so it's physically impossible for me to get the full gigabit of Internet they sold me.
They most probably sold you 'up to 1 Gb' bandwidth, not just '1 Gb'. Overhead is about the same in these cases. Your losses are negligible. It's more painful having 4-5 (on worst time periods/peers) or 6-7 (on best) of the 'up to 10 Gb' (clearly sold as such) fiber access I have.
Legally they are physically unable to provide the gigabit they claim I could get.
That's the problem here.
Sure, due to the shared medium nature they do not promise to always have even particularly close to a full gigabit available for me, but that's documented according to the 3 residential internet SLA thresholds the BNetzA (Germany's FCC; except they also regulate power and gas grid) defines and that a provider has to cough up numbers in an info sheet at the time of sale.
The issue is that if they are physically incapable of delivering the up-to they sell and it's not due to the unpredictable nature of e.g. radio reception strength or POTS wiring quality (ADSL), this very quickly very strongly reeks of fraud.
Even just a little bit is fraud, just as systematically under-delivering e.g. gasoline would be. Think if you bought that in cans and they say they're e.g. 5 gallon (or 20 liter) each, and at nominal temperature, none of the cans you can actually find for sale end up having the full quantity, always being at least an ounce (~30ml) short.
By law the demarcation is a passive one; the provider is not allowed to mandate you operate ANY of their active hardware. If they want to sell you internet only via e.g. RJ45 Ethernet they better consider asking your landlord to rent them space and power and Cat.5(+) wiring access to put a switch/router, because by law they can't dump that on you the residential apartment renting customer.
You may either rent/buy a device from your ISP, or you may bring your own, at your discretion. ISPs are required to accept all devices, of course if your device kills the network segment, they will kill your connectivity. But they can't refuse to let you connect.
You get taken to court and sentenced to pay the damages? Same thing that happens with the TV cable that runs through the whole street. Or the cars parked openly along the road. If you damage it, you pay for it.
Controlling your hardware without consent that they legally can't ask for would be illegal hacking.
They do however have the right to mandate certain configuration parameters just how they are allowed to mandate you connect something that isn't a noise generator to e.g. a cable TV outlet. Well, being able to limit you to connect devices that conform to some spec.
Ok, `io_uring` (like NVMe but for IO commands from application to kernel) and DBSP (high-grade framework for differential (as in, based on Delta streams/diffs not full updates) compression of "incremental view maintenance", it can keep materialized views synchronously up-to-date with a cost proportional to just the diff (for most typical ones; certain queries can of course be doing things at an intermediate stage that blow up and collapse again right after)).
At least notably; not sure about the MVCC `BEGIN CONCURRENT`'s practical relevance though; I am just already familiar enough with the other two big ones to chime in without having to dive into what Turso does about them...
> Ok, `io_uring` (like NVMe but for IO commands from application to kernel)
Are there benchmarks comparing turso with io_uring to sqlite (with other config the same)?
io_uring has the potential to be faster but its not garunteed. It might be the same, it might be slower, depending on how you use it. People bragging about the technology instead of the result of using the technology is a bit of a red flag.
I have about 1500 lines in my VSCode settings.json dedicated to custom syntax highlighting and text decorations (this could be trimmed, some is from before the days of semantic highlighting), but regardless, the amount of differentiation I can achieve with this is simply not possible on a light background. I've tried! (Solarized light is a nice theme though)
