Even if they were, flying in restricted airspace is not against the rules when talking to ATC.

Not sure anything is enhancing. Approaches have… always been documented? What has greater range - VORs? I haven’t seen any. I think it’s reducing everything to MON that’s it.

Don’t many CRE buildings do exactly this, and have been for years? As a notable example, Goldman building built in NYC over 10 years ago: https://chenected.aiche.org/2014/08/goldman-sachs-new-deep-f...

CTO of an HFT firm here. My opinion: repo (and probably author’s comments) are LLM-generated. That said, many questions and techniques touched upon are real. So even though I certainly would not use any of these verbatim (as I wouldn’t do w

It does not. If this was the case, round trip wire to wire latency below 1.0-1.2 microseconds in software would’ve been impossible. But it clearly is possible - see benchmarks by Solarflare, Exablaze, and others.

Is it a coincidence it’s 42 megawatts and not 41 or 43?

They were most definitely IFR. Not because of the weather but because IFR is required above certain altitude 18,000 ft in the U.S. and typically lower in Europe (depends on a country). Jets including small private jets are almost always on

Russian propaganda does not say that. Putin himself said on multiple occasions that any theories of staging moon landings are silly. Don’t have a reference at the moment but I have seen several Putin’s interviews to that effect. Russian pro

One does not need a lot of bandwidth to trade successfully. In fact, a limited number of signals agreed upon ahead of time is enough. E.g. signal “A” could mean “buy 10 contracts”, signal “B” - “sell 100 contracts”, etc. And you can of cour

Respect and courtesy are nice but I think the reason this style is so effective is different. It makes the counterparty believe that you are collecting the paper trail to file a lawsuit. And behaving like you are preparing to file a lawsu

And I know a business owner who is shopping for a new house after getting a PPP “loan”. Sure, PPP money is supposed to be used for payroll. No problem, one can indeed use PPP money for payroll 100%. But then use the business revenue, 90% o

Why do we pay taxes then if the government can just borrow that money?

So, what if a business was successful, not impacted by covid, and wasn’t planning to lay off any employees anyway? Say, technology consulting company with 100 employees. Took out a PPP “loan”, which will be promptly forgiven since they kee

Comments about storage costs are nice theory but don’t tell me those storage costs went up 50 dollars a barrel to cause CLK0 to go from +10 to -40 within something like 30 minutes. It was all forced liquidation by brokers like IB and people

Strategic Petroleum Reserve uses salt caverns to store crude oil and has the capacity of 797 million barrels [1], which is equivalent to roughly 500-700 larger tankers. Both construction cost and carry cost per barrel are, of course, much l

Would creating, say, online marketplace to help people lose desired amount of money with certainty - for example, via some sort of specially crafted financial instrument - violate any applicable rules & regs? Idea for the next YC bat

I hope one day we stop comparing rail to cars on passenger-mile basis - like infrastructure costs per passenger-mile. These are apples and oranges. There is zero similarities between riding on modern trains and driving. I’ve taken hundreds

This is great but what jurisdiction does SEC have over Ukrainian entity? Sounds a bit like robo-callers with gozilian in fines issued and near zero collected.
