KK7NIL··on NIST scientists create 'any wavelength' lasers
The velocity factor is usually 0.6-0.7, never seen it as low as 0.5.

And it's set by the dielectric, not the conducting material.

KK7NIL··on NIST scientists create 'any wavelength' lasers
No, the problem is getting a high power (hundreds of watts) and high uptime EUV source, there's no reason to think this is a step towards that at the moment.
KK7NIL··on NYC to open municipal grocery store in 2027
> If someone is stealing your only $20 out of your pocket and I stop them and you now have $20 in your pocket, I've just created conditions for commerce on the part of you taking that $20 and spending it someplace else in the market than on the thief.

Grocery stores aren't thieves, they're largely pretty terrible businesses with extremely thin margins.

But, to engage with your ridiculous bait and switch: whether I or the thief have $20 is irrelevant to the commerce as he'll presumably spend it at the market too, so even this ridiculously contrived example falls flat on its face.

> rich person bids up Tesla stock and makes Elon into a billionaire off a PE of 317 now, thin air pumped into the balloon in other words with all this money tied up in overpriced TSLA stock than empowering real work in the economy.

Here you go again with some ridiculously biased example, but I'll engage with it for your own sake: money that's invested doesn't just disappear, it goes into the pockets of employees and suppliers or gets reinvested in some other way, continuing the cycle.

> What do you believe the role of government is?

Limited.

KK7NIL··on NYC to open municipal grocery store in 2027
That post was not at all worth my time, it just cherry picked data without ever putting it together to show intentional price manipulation or monopolistic behavior (no, showing concentration isn't enough).

> They can't do anything about cartel behavior.

Incorrect, several states have passed their own antitrust laws, there's nothing that limits it to the federal government.

> The government engages in commerce all the time. If we took that argument to its logical conclusion there would be no libraries as they compete with book stores. There would be no armies as they compete with Blackrock mercenaries. No public transit as it competes with private transit. No public events as that competes with ticketmaster. No public schools. No public universities. No scientific research grants. No sheltering or feeding the poor. No treating the sick. No treating veterans. No bridges. No roads. No harbors....

I do think the government should get out of many of those, so your argument doesn't really land for me.

> No, it seems a big role in this country for government is facilitating conditions for commerce.

I don't see how the government driving out competition by running its own grocery stores, presumably at a loss, is "facilitating conditions for commerce".

KK7NIL··on NYC to open municipal grocery store in 2027
Those are pretty extraordinary claims with very little evidence.

And, even if they are true, the obvious solution would be to enforce the already existing antitrust and competition laws, not to have the government directly engage in commerce.

Both BJTs and FETs have intrinsic exponential/logarithmic behaviors (at low biases) due to charge density being given by the Fermi-Dirac distribution since electrons are fermions.

> I strongly object to anthropomorphising text transformers (e.g. "Assisted-by").

I don't think this is anthropomorphising, especially considering they also include non-LLM tools in that "Assisted-by" section.

We're well past the Turing test now, whether these things are actually sentient or not is of no pragmatic importance if we can't distinguish their output from a sentient creature, especially when it comes to programming.

KK7NIL··on Netflix Prices Went Up Again – I Bought a DVD Player Instead
Prices keep going up and bitrates down because most streaming services (except for Netflix and YouTube) have been basically break-even or money losing for years now, and the appetite for that is cooling.

Also, display resolution is not scaling like it used to. The move up from 4k to 8k is far more expensive and less worthwhile than the previous jumps.

So, I think your assumptions about the business side of streaming and the way the hardware is scaling are wrong and we will, in fact, not see physical media make a comeback.

KK7NIL··on Netflix Prices Went Up Again – I Bought a DVD Player Instead
> I think physical media might make a bit of a comeback as screen sizes increase unless streaming services up their bitrates.

The latter sure seems a lot more likely than the former, my man.

KK7NIL··on NYC families need over $125k in income to live in any borough
> why do we allow companies to do this? It should be trivial for the people of Kansas and Missouri to come together and say we won't allow a race to the bottom.

This is prisoner's dilemma 101.

Or, less cynically, cities compete in a free market where they try to compete for a limited amount of capital investment; there's nothing wrong with a city offering more attractive terms to be more business friendly, if they so wish.

KK7NIL··on Solana Drift Protocol drained of $285M via fake token and governance hijack
Seems to be very standard now a days as projects seek to do things that can't be done fully on-chain.

You'd think they'd take a step back and ask "why is this even a token then?".

KK7NIL··on A forecast of the fair market value of SpaceX's businesses
You seem to have read some sort of political opinion into my post that is not actually there.

I was just making a joke about the outrage OP is showing, I wasn't making a judgment on whether they get taxed too much or too little.

Nothing like a forced tax event to get the people rioting in the streets!

KK7NIL··on Mystery jump in oil trading ahead of Trump post draws scrutiny
There's no "proven evidence" (whatever that means) that people in the Trump administration are insider trading either, yet we can see some very suspicious ripples in the market.

Pelosi was even more obvious as we know all of her trades, their timing and her outrageous outperformance during that period.

No idea why you're getting downvoted, this is absolutely true.

The people have lost faith in both parties, we now expect our leaders to be cronies.

KK7NIL··on American Aviation Is Near Collapse
I agree, but the article does specifically mention crashes as a symptom we're already seeing:

> Fatal crashes, overstressed controllers, and endless security lines reveal a system teetering on the brink of failure.

I have not read the entire article (paywalled), but the introduction sure seems to strongly imply that we're already seeing an unusually high rate of crashes.

KK7NIL··on American aviation is near collapse?
1. Not really. If the crash rates we're seeing under the Trump administration are higher than any similar length period in the last ~10 years, we should start to worry.

2. See above.

> "Collapse" isn't within the statistical distribution though

Uh? Maybe you could explain what you mean by this a bit more.

KK7NIL··on American aviation is near collapse?
He means that anyone making an argument that aviation safety has deteriorated should be using the stats to back it up, instead of anecdotal evidence.
KK7NIL··on From Oscilloscope to Wireshark: A UDP Story (2022)
Yeah, I used to work at Tektronix, this looks like an A unit.

Also, the 50GS/s is actually more like 25GS/s as it has a Nyquist frequency of 12.5 GHz. This is because they take 2 samples at the same time, instead of 180 degrees out of phase. I wish they had made that clearer to customers, it felt misleading to some.

KK7NIL··on From Oscilloscope to Wireshark: A UDP Story (2022)
A Keysight UXR can do one quarter of that, 256GS/s, but a Tektronix 6 series is limited to 25 GS/s iirc, so you're right.
KK7NIL··on US SEC preparing to scrap quarterly reporting requirement
> What need is the 24/7 trading solving?

There's a reason the Black-Scholes model assumes market prices are continuous. The discontinuity of the market makes hedging options a lot more complex and expensive.

24/7 trading doesn't completely fix that, but it does help.

KK7NIL··on US SEC preparing to scrap quarterly reporting requirement
> it used to be raise money.

What in heavens gave you that idea? A well developed public stock market is such a new (and American thing) and it still makes up a small amount of the capital raised by businesses.

Even within large public companies, there's significant use of bank/private debt.
