I can't speak to the quarters but you absolutely can snap windows to the left and right halves in MacOS.

i do quarters all the time. it used to be with third party apps. iu think its native now

I've heard people say this but it really only makes sense if you don't think about it for more than 10 or 20 seconds.

Prediction markets by definition always resolve to one side being completely wiped out and losing everything. Stocks going to zero happens pretty seldomly, in prediction markets it's guaranteed to happen every single time.


Prediction markets are not binary options. They are closer to a liquid equity option market (and most equity option markets aren't liquid at all). That means you can trade into and out of positions at any time and for different prices depending on where the market is. You can even do time spreads where you can't lose it all no matter what happens. Maybe your 10 or 20 seconds of thinking wasn't as perfect as you think since you don't seem to understand how prediction markets actually work.

That's only true if you leave your money in...which you don't have to do.

You can play prediction markets by betting on a swing. E.g. I made a few hundred dollars betting on Harris in 2024 when Trump was at ~65% odds and then selling before the election when it was closer to 50%.


> can play prediction markets by betting on a swing

The outcomes are still capped. In that respect, it's more like a derivative market than the stock market. You can trade in and out of options. But the value in the system is tightly defined and, after fees, a net negative-sum game.


There are no fees on Polymarket. Not sure about others.

"Currently, small fees apply to Crypto and Sports markets.

More critically, Polymarket doesn't pay interest on deposits. (Kalshi does.)

Thanks for the correction! I have to admit it was a while since I last looked into this and I shouldn't have been so confident.

There is a fee implicit in the market spread. It's formed out of the time value of money w.r.t. the cost of NOT trading as well as the adverse selection faced by those with standing offers.

Increased insider trading will increase spreads.


Then explain why the average prediction market has a smaller spread than the average equity option market.


In that case you limit your upside as well as an insider, and have to deal with liquidity and slippage coming and going.

So options markets then?

It's the only thing that works at scale.

If you want to support them you're more than welcome to message them and ask for their Venmo, or reach out to their agent (if they have one) or them directly and ask who to make the check out to. That just doesn't work at scale.


Because Blockbuster Video played a pivotal role in early-1900s segregation in the United States?

I think it's much more likely it's just a reference to extremely popular and economically successful movies but happy to be proven wrong.


The movie term derives from a different piece of slang, a WWII term for a large bomb that could destroy an entire block.

Before movies bombing was a bad thing, a successful movie was "exploding" like a blockbuster bomb.


Yeah I heard it describes a movie where the line to get into the theater went around the block.

edit: ah, but wiki disagrees <https://en.wikipedia.org/wiki/Blockbuster_(entertainment)>


It is possible for ATC to be understaffed as a profession, LGA to be understaffed as an airport, individual controllers to be overworked, and for it to be 100% reasonable to have a single controller at LGA in the middle of the night.

"Staffing shortage" doesn't mean "you can fit more people in the tower."

You can't think of any scenario having one controller makes sense?


In general, I can. In LaGuardia? Aside from right after 9/11 and during COVID-19 when almost all commercial travel stopped, I cannot.

I don't think people saying this stuff quite understand how busy LGA is even at night. I'd even go as far as to say that three minimum on duty with two in the tower at all times (for a ground/air split), would be the bare minimum for any hour or situation at LGA.


It does quiet down eventually. There's no scheduled departures 22:55-5:45 and only a handful of arrivals 23:59-6:45.

However, arrivals stay pretty heavy right up until 23:59 even on schedule and if you've got a lot of delayed flights (not exactly uncommon at LGA) - you may still have a lot of departures going out in the 23:00 hour.

I would not be surprised to learn that they're staffed to an appropriate level for what the schedule says is supposed to be operating at that time, but a very inadequate level for what actually winds up operating at that time on many days.

Initial analysis suggests they were running about 75% of full capacity in flight ops in the 15min prior to the accident. I doubt they were staffed to 75% of the daytime peak.


When the airport is closed, in case there was an emergency that needed to reroute. One person on then makes sense?

La Guardia appears to handle 400 flights a day, 22 an hour. I see 6 moving planes right now (https://www.flightradar24.com/airport/lga); hopefully they have more than one person on?


400 flights a day is 16-17 per hour and those are going to be mostly during the day. As someone else points out there is a ~6 hour stretch overnight with no scheduled departures. That's somewhat common even at large hubs.

I don't want to blow your mind but if the airport closes there aren't going to be any controllers in the tower.


I accounted for 'closed' hours. Hence 22/h. The incident in question was close to closing time, but there were 2 issues, one a declared emergency.

Likely, the problem was with truck 1 wishing to get to the emergency quickly. There was at least one queued landing hence the go-around demand after the crash.

It doesn't blow my mind, but at a major air hub like LGA I'm surprised there isn't a controller on site for callout?


You can't think of any scenario having one controller makes sense?

At one of the nation's busiest airports? Where there are two intersecting runways, both potentially with departing and arriving aircraft? Nope.

But, sure, a single-runway regional airport can probably get by with a single controller.


You're 100% right, a "Trump-friendly" administrator has been "installed" so we can't trust the FAA's conclusions. The last guy quit so this guy is definitely going to lie.

Planes landing at a rate of one every 30-40 minutes isn't exactly "overworked."

I don’t have time to check flight logs but I personally landed at LGA coming from MDW on Sunday. And I also know people who got diverted within the hour coming back to LGA that night. 30-40 minutes doesn’t seem accurate. That aside, if you’ve ever done operational staffing, you’d know that you should probably have at least one redundancy. When there is any chance of emergency or two events happening simultaneously, you should have more than one person.

One last meta point. We live in the wealthiest country in the history of the world, and the highest air travel prices (some part is a function of longer distances I know). We should expect that we have ample coverage, if not over-coverage, at all times for one of our major metropolitan airports. Pay them.


Almost every night there are 6-7 hours with zero or near-zero scheduled departures and very few scheduled arrivals.

The controller shortage has nothing to do with pay, controllers make a lot of money.


Ten hours a day, six days a week, and forced resignation at fifty six. I doubt it pays good enough with the amount of burnout a job like that brings.

My point was more that when this occurred, it wasn’t dead.

12am-5am is very quiet, at about 1 per hour. But the accident happened during the 10pm-12am time slot, which is not as busy as other times of day, but can still have workload spikes as evidenced by this situation.

ATC should never work alone at any of the "Core 30" airports. https://www.aspm.faa.gov/aspmhelp/index/Core_30.html


In this case there were two arrivals within 4 minutes of each other and two departures, in addition to the emergency plane that had just aborted takeoff.

Which is a completely reasonable amount of traffic for one controller to handle. This wasn't the controller's fault. The firetruck received a clearance, had that clearance revoked, and either didn't hear the revocation or ignored it.

If you have ever spent time listening to LiveATC you will realize that like everyone, "tunnel ear" is a real thing - if United 1002 has received the clearance/instructions they expect, read them back, and are proceeding it can be moderately difficult to get their attention again, even with perfect verbiage.

The controller was not guilty of malfeasance, but clearing the trucks onto the runway with an airliner on short final was a mistake, no matter whatever else one could say about it.

What is the contingency/continuity plan if the single controller becomes incapacitated while on duty with no warning to pilots?

Same as if the radios stopped working or otherwise communication fails. Execute the planned procedures (which vary).

Often Approach will take over the "tower" and operate in crippled mode (no clearances to cross active runways, you must go down to the end kind of thing).

Some airports are uncontrolled at various times and would revert to that. Some airlines would require the pilot execute a missed approach and deviate to a towered airport, others may allow them to land.


> the controller in question was working both ground and air control simultaneously due to staffing shortages

How many planes land at LGA in the middle the night?

One controller overnight is completely reasonable.


Approximately one per minute in the 15 minute span proceeding this crash, including one that had an emergency takeoff rejection and was being maneuvered along with the emergency support vehicles that were being sent to attend to it

>> One controller overnight is completely reasonable

So if said controller has a medical episode?


That risk is managed through medical certification. The real problem with understaffing is that one person can't handle all that work.

"Funny" enough if this controller had had a medical emergency (or just bad sushi) and been off the radios, this wouldn't have happened because the fire truck would not have received clearance to cross the runway and wouldn't have. Or at least would have crossed like the airport was uncontrolled, been much more careful and announced itself, and likely have seen the landing aircraft.

And if an aircraft needs to land due to an emergency? It’s amazing things work as well as they do, the system relies on only one thing going wrong at a time. This accident was an example of multiple things going wrong at the same time.

Every accident is an example of multiple things going wrong at the same time.[0]

I'm going to pretend to know exactly what would happen in that precise scenario but I'm confident most commercial pilots get enough training to be able to handle it.

>> Every accident is an example of multiple things going wrong at the same time.

You are defeating your own argument :-) Its exactly because every accident is an example of multiple things going wrong at the same time...that you need...multiple layers of control and safety to catch it through each hole of the cheese.

Like...another controller?


One of the things you learn as a pilot is how to recognize that you need to go into emergency mode if you will. Call it high-alert if you want.

You need to recognize when something is out of the ordinary and treat it as an emergency (perhaps not a literal pan-pan/mayday emergency) sooner rather than later, and do things that may end up to have been unnecessary (like executing a go-around because emergency vehicles were on the move).

One controller on two frequencies is another example - that works fine in normal situations, but during an emergency response, perhaps the channels should be mixed; giving the pilots in the air a chance to hear the incorrect clearance onto their runway.

After all, an active runway is really more of an "air" control thing than a ground one.


An empty tower at La Guardia with a bunch of airplanes in the air not getting a reply to their calls is Die Hard 2 stuff. Spare me the Pete Hegseth school of ATC...

I have absolutely no idea what you're talking about. The GP is literally about a lone controller in the tower having a medical episode and what would happen after that.

The pilots would execute untowered approach procedures, a small airport with little to no traffic and VFR flight you may self-announce on frequency, a larger airport you go back to approach, etc.

Each of those flights should have an alternate and be prepared (have enough fuel) to divert. If there is a fuel emergency then self-announcing is likely appropriate as the plane is coming down anyway, but that is multiple things going wrong.

A big part of it is what category of airport it is, and plane. General aviation almost always goes to self-announce (which includes some business jets perhaps, they often land at untowered airports) but not category 135 air travel or whatever it is.

I can’t find a way to read this other than

“If we remove regulation and safety controls, things will be safer because everyone will be more careful.”


You should try harder, because I'm not making any comment on regulation whatsoever. There are procedures that every controller and pilot knows for how to handle loss of radio contact.

Am I misunderstanding the implication in your comment that things would have been safer had there been no ATC at all?

Because the parties involved would be more careful if there were no ATC?


And we know how well that works: https://youtu.be/AWM0l8_F_X0?t=411

Can a single human being reliably and robustly maintain a safety-critical system alone under any circumstances, ever?

Ever?


I design and conduct space missions, and I'm an experienced professional pilot. The answer to your question is "never."

Any system that requires perfect performance from any one human will fail.


There are millions of people who are self employed in an industry where they could be maimed or killed if they screw up who manage to make it to retirement.

I think the better question is how you get a system in which people are only responsible for any one facet to get the same performance out of people that a painter can get out of himself when he's setting up his own ladder that he personally has to climb on.


I don't think the GPs point is about personal safety of workers, but rather critical safety systems that rely on one person with no backups. Like an ATC tower for a busy airport staffed by a single person on an overnight shift.

A painter who does a bad job setting up a ladder is going to have a bad time, a lone ATC operator having a heart attack potentially puts multiple large aircraft full of people in danger...


The goal should always be to reduce the human dependency - where reasonable which is where all the argument is, because of the cost/benefit analysis.

Mandatory scaffolding for roofing contractors would save some amount of deaths/injuries (and the related expenses) but add expenses to each job.

Some roofing firms refuse to operate without scaffolding; you pay for it or you find someone else.


Normally? Zero. LGA has a curfew from midnight to six AM, April 5-December 31.

In practice? It depends. Delays have a tendency to cascade in the air travel system and the Port Authority can curtail or cancel the curfew at their discretion. How frequently do exceptions to normal ops have to happen for it to be unreasonable to use "normal ops traffic" as a justification for scheduling a single controller? Ultimately, controllers have to control the traffic that they get, not the traffic that they want/expect to get, and a system that is overly optimized becomes brittle and unable to deal with exceptions to the norm.


For a major airport the answer is always no. LGA is in the 20 top busiest airports in the nation serving it's largest metro area.

If LGA was a small regional airport, sure one controller or maybe even no controls overnight could be appropriate. But LGA is not a small regional airport.


> One controller overnight is completely reasonable.

How many fatal accidents are reasonable in your opinion?


Looking at the things he needs to juggle at the same time, is it really reasonable? Any standard we are referring here? Sure such cases are rare but that's why we have redundancies for critical positions.

> One controller overnight is completely reasonable.

Do you really think it's appropriate to have zero margin for handling unusually high ATC workloads? Because we just saw what happens when you have zero margin for handling unusually high ATC workloads: people start dying.


Yes, it's complicated. There's almost 1,000 generals and officers spread across the US military. They (and the tens of thousands of people directly supporting them) spend a lot of time on these things.

Sometimes "draw the rest of the owl" makes sense when you've got 20,000 people actively drawing owls all day every day.


I'm generally sympathetic to the argument that there are a lot of experts doing expert things who know better about these things than some idiot sitting at his computer i.e. me.

But in this particular case, we're in the middle of a war where the owl didn't get drawn and the enemy has successfully launched thousands of drones and missiles at our forces and our allies, causing enough damage to severely disrupt the world economy.
