Well, their Discord server is right on their front page, so he's pretty easy to find.

Ah ok I didn't realise that. I only use discord for non work related stuff and never with my real identity. That makes sense though. I still view it as a gaming thing somehow.

Also not SCPI (Standard Commands for Programmable Instrumentation), widely used to control lab instruments and pronounced similarly ("skippy").

Oil futures are infamously not cash settled, which is why they went negative during COVID.

People just don't like the "both sides are the same" clownery anymore. It's not true and will never be true.

So are you asserting that Nancy Pelosi wasn't insider trading when her party was in power?

I think he is asserting she never created a policy, tweeted or manufactured a war for her insider trading: it was purely opportunistic.

Yes I am asserting that, there is no proven evidence she was. Congressional stock trading is legal.

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.

Trump is out here running crypto rug pull grifts as the president to enrich himself and his family while holding office. This hand wringing about Nancy Pelosi is just slopulism. She just invested in SF tech companies and they happened to do well.

You’re complaining about the buffet while the titanic is going down.

Sounds like it's working as designed!

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

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

1. It's not a rigorously defined term.

2. "System collapse" would be unexplored territory, so how would statistical analysis be able to infer when it occurs?

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.

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.

This is a common kind of "data or nothing" fallacy. Data doesn't reliably capture evidence for the thesis "TSA agents and aviation workers are burning out and ICE is going to make it worse". The part that data is good for hasn't happened yet over a long enough timeline to reflect properly.

If the argument is "deadly accidents are up over the past decade", then yes, of course, we must point to data.

If the argument is, "the aviation industry might be on the verge of a steep decline in availability and/or safety due to recent political/financial problems", then what do you mean "show the data"? That doesn't make sense. It's a concern based on observation, which is fine if it's not presented as a fact.

And if it turns out that a specific accident is due to said forces - what, we don't address those forces, because "data"?

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.

+1 but this is The Atlantic so having a reasonable expectation would keep you sane.

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.

Looks like max 50GS/s per their site. That also looks reasonable with the screenshot they have in the article showing 1ns / div horiz. But clarity on the data would be lovely. =)

Actually I take it back: For the series 6B spec page... Real-time: 50 GS/s (2 channels), 25 GS/s (4 channels), 12.5 GS/s (> 4 channels) Interpolated: 2.5 TS/s

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.

If you are an absolute nutcase, you could characterize a set of line stretchers and a multiplexer on a high end VNA then offset the inputs of the 4 channels on that UXR with them, take a capture and finally rebuild a 1TSamp/s signal out of the 4 results.

You have to have the 240V model of the scope to run all four channels at full rate (110GHz) though.

The older Tektronix TDS540 series did this, but at much lower rates as was common in those days though. Internally there are differential feeds from the very beautiful hybrid ceramic input boards to 4 DACs, with some clever switching so that a single input can be sampled by all 4 DACs with a suitable offset to create 4x the sample rate when running with all 4 inputs.

The calibration procedure on the scope fiddles with the time alignment to get the different DACs correctly offset so that the combined signal is correct.

The hybrid ceramic input boards in their metal cases are a thing of beauty, fragile (don't ask how I know), but beautiful.

Yup, a lot of scopes actually did this internally and some still do. It's part of why some scopes lose half their BW when you go from 2 ports to 4 ports (some go the other direction and run multiple ports on one very fast ADC), they split the digitizers. It's just very very difficult to keep it working external to the box mainly because of line drift.

Take that Nyquist ;)

> 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.

> 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.
